DESCRIPTION OF THE INVENTION

The invention relates to a modular system for the heating device, in particular operating on liquid fuel a water or air heating device in a vehicle as an additional heating device or a heating device with the engine off.

Heating device, in particular an additional heating device and / or a heating device with heater, should be arranged so that they can be used in various structural and spatial terms. Accordingly, the heating device of this type have a very compact design in relation to shape and size. Also, preferably, the connectivity of the heating device and its function are flexible, in order to harmonize with the existing heating devices and special conditions of installation of the customer's wishes. Furthermore, the heating device must have a large capacity and a high efficiency.

Individual approval of the heating device with the relevant installation conditions are very difficult and expensive. As a compromise, you can consider the possibility of creating different models with different shapes and sizes, and the next one or the other is more or less suitable for the respective installation conditions. However, the manufacture of various embodiments and is relatively expensive.

The basis of the invention is to provide a heating apparatus of various embodiments inexpensively.

This problem is solved according to the invention by a modular system with features of claim 1.

The invention is based on the general idea to create a modular system for the block principle to the embodiments of the heating device, which does not change the basic module to which various attachments may be attached modules and various air supply modules which can be combined in different ways with each other. Thus, it is possible to mount several, but at least two different embodiments of the heating device. Since different variants of the heating device based on the same basic module which contains essential and, in particular, in the development of expensive components, such as the combustion chamber and the heat exchanger can significantly reduce the cost of creating variants. With the modular system according to the invention can produce at least two basic types of heating devices. The first main type comprises a first air supplying unit which is mounted on the main module position in the axial direction is substantially coincident with the main module. Moreover, for generating a first basic type is first mounted module which is configured relatively flat and has a slot through which the established state of the primary module provides access to inputs from the outside of the heat exchanger through which the supply (inlet and outlet) of the heat exchanger of the heat exchange medium. Thus, a compact overall construction with a low height. In particular, the axial length of the first principal type greater than its height. This elongated main type of heating device is suitable, in particular, to provide an additional heating device, which can be installed in a standard automobile.

The second main type of heating device is formed by the fact that the main unit have the second air supply module and a second module is mounted. The second module is mounted in a module mounted on the main state completely surrounds the heat exchanger inlets and quasi mentioned above conclude it in himself. The second air supply module mounted on the main unit able to perform in the axial direction substantially coinciding with the base model, and attached to it a second half unit. Accordingly, the second basic type has a greater height than the first main type mentioned above. Due to this, it is preferably an axial length considerably shorter than that of the above first type. In particular, the second basic type of its height greater than its axial length. In accordance with this second type can be formed particularly compact and is therefore particularly suitable for implementation as a heating device with heater, which can be installed in the engine compartment and in the future.

Components of the modular system according to the invention are preferably selected so that the first air supply module, a first embodiment in which the air supply module contains a blower which sucks in fresh air and / or pumps to the combustion chamber, the air delivery unit is provided and a second embodiment, wherein the air supply unit is adapted for connection to an external fan. In this way, for each of the main types of options can be a heating device, which either contain within itself the necessary supply of fresh air fan, or are capable of connection to an external, separate location of the fan. These options provide additional coordination with the existing spatial conditions.

In particular the modification in the first embodiment, the fan air supply unit may be positioned so that the prescribed condition on the main unit of the fan rotation axis extending substantially perpendicular to the longitudinal axis of the main module. This ensures a relatively elongated design created for the heating device.

and an embodiment is possible in which the fan according to the first embodiment of the air supply unit is disposed so that the module mounted on the main axis of fan rotation state extends substantially parallel to the longitudinal axis of the main module. In this embodiment, the second air supply module is considerably higher than the first air supply module and can be based on the location of the fan is made relatively flat, i.e. length of the second air supply module in the axial direction of the main unit is less, in particular considerably less, than measured at right angles to his height and width.

Another degree of integration can be achieved due to the fact that the second hinged module has a fuel pump and / or pump for the heat exchange medium. Thus, along with the integration of the control unit, respectively, placing the control device, the hinged second module adds extra features.

To ensure at a particularly compact design of sufficient power, but also acceptable values ​​radiation a modification of performing the combustion chamber, so that it acts in the axial direction in the zone of the first connection point, through which the corresponding air supply module can be connected to the main unit, and when attached to main air supply unit module included in it, while the air supply unit has a corresponding recess. In this way the combustion chamber in the axial direction is longer than its surrounding coil. Increased structural length of the combustion chamber provides a combustion with less release of harmful substances, while the heat exchanger is arranged appropriately selects from the combustion chamber maximum heating power. Located in the air supply unit is preferably disposed inside the recess the fresh air supply channel, thereby to axially protruding combustion zone is provided sufficient cooling.

Another preferred embodiment is provided when the pin fitting incandescent bulb projects axially into a first zone and at the point of connection established in the main air supply module into it, and the air inside the module comprises fresh air channel corresponding recess. Thus, in this arrangement the pin fitting incandescent bulb is inside the fresh air supply duct and thus in an area with a relative excess pressure, so that the glow plug nozzle holder should not perform additional sealing function and can therefore be made relatively low.

Further important features and advantages of the invention follow from the dependent claims, the drawings and detailed description of the invention corresponding to drawings.

It is understood that already mentioned and to be subsequently described features can be used not only in the respective given combination but also in other combinations or alone without departing from the scope of this invention.

Below is a detailed description of a preferred embodiment of the invention shown in the drawings, which schematically shows:

4 - heating apparatus according to the second basic type in the second embodiment,
a perspective projection

As shown in Figure 1, the modular system 1 has the main unit 2, 3 includes a combustion chamber surrounded by a heat exchanger 4 which is at the same time the main unit casing 2. The heat exchanger 4 by means of two bushings 5 ​​(input and output) may be connected to the heating contour. As the heat exchange medium used is preferably a liquid, in particular water. Insertion of the heat exchanger 5, in this case made in the form of nozzles extending opening; however, you can perform inputs and 5 of the heat exchanger in the form of input ports into which you can insert the appropriate fittings.

Combustion chamber 3 is substantially cylindrical, according to this heat exchanger 4 at least in a cylindrical shape, so that the main unit 2 has a longitudinal axis 6.

At one axial end side 7 of the main unit 2 is installed with the possibility of fixing the base plate 8 which serves to set the combustion chamber 3 in heat exchanger 4. In addition, this support plate 9 is fixed fitting pin 10 with the ignition plug. Furthermore, from this base plate 8 moves in the axial direction of the combustion chamber portion 11 3. Fuel supply line is indicated at 13. In addition, mounting the seal 12 is necessary.

Fittings 5 ​​inputs respectively of the basic module 2 of the heat exchanger 4 are parallel to each other and to extend from the longitudinal side 14 of the main unit 2. This longitudinal side 14 extends substantially in a plane parallel to the longitudinal axis 6.

Furthermore, the modular system 1 has several, in this case three hinged module 15a, 15b and 15c, each of which serves as a housing for the heating device of the undepicted controller. In this case the heating device is a control device is already integrated can be mounted in these modules. It is also possible to set an appropriate heating device controller on the main unit 2, and then close it when installing the relevant module half.

At the same time the first hinged unit 15a is made relatively flat so that it does not appear in the installed state of the input nozzles 5 of the basic module 2; Conversely, opening fittings 5 ​​in favor of the first set 15a mounted module. This first plate is hinged 15a extractor module 16, which is facing the main unit 2 forms the inner side of the slot above the heating device control. Furthermore, the first module 15a is mounted to enter each heat exchanger 5 a slot 35 which in the mounted state surrounds three sides of the corresponding heat exchanger 5. By entering this heat exchange inlets 5 are easily accessible from the outside when the implement mounted first module 15a.

In contrast, the outboard modules 15b and 15c form two different variants of the second coupler module 15b, 15c, which in relation to their height are markedly different from the first coupler module 15a, in particular the two hinged module 15b and 15c are made non-planar. In the assembled state two hinged module 15b and 15c overlap undepicted device along with the heating unit 5 and outputs the control main unit 2. In this case these five inputs connected with respective inlets inside 17, which are formed on the respective second wall-mounted module 15b and 15c. To provide easy assembly to be joined with each other inputs 5 and 17 are designed as plug connections, which ensure a tight connection due to the simple process pushed on.

To form the first embodiment in the second module 15b is integrated the implement pump 18 to the heat exchange medium and which is commonly called water pump. When mounting this second coupler module 15b corresponding to the inlet 5 of the heat exchanger 4 is preferably connected via a plug connection to a corresponding input, the output of the pump 18, respectively.

To form the second embodiment shown here the second hinged module 15c has a fuel pump 19 at its upper side, which is provided with a fuel supply to the burner undepicted. By mounting the fuel pump 19, accordingly the water pump 18 mounted in a corresponding second module 15b, 15c are formed easily installed modular units that provide a compact design of the heating device.

Furthermore, the modular system 1 according to the invention has several, in this case three modules 20a, 20b and 20c of the air flow, each of which has an input 22 for fresh air and an outlet 21 for the exhaust gases. Furthermore, each of the air supply module contains within the channel for exhaust gases, which in the mounted state leads coming from the heat exchanger 4, the cooled exhaust gases to the leading outwards input for the exhaust gases, which in this case forms an outlet 21 for the exhaust gases of the corresponding air supply module . Input 22 for fresh air to the embodiments 20a and 20b formed as facing outwardly inlet for fresh air, while at 20c embodiment, it passes inside the module 20c of the air supply and receives fresh air, for example, from another location associated heating apparatus, for example via the corresponding the second hinged unit 15b, 15c.

For these modules, the air supply is provided with at least two different variants. Accordingly, the modules 20a and 20b form a first module 20a, 20b respectively supply air whose cross section (transverse to the longitudinal axis 6) is substantially coincident with the cross section of the main unit 2. In contrast, the embodiment 20c forms a second feed unit 20c air, whose cross section substantially corresponds to the cross section of the basic module plus a cross-section of a mounted second modules 15b or 15c.

The first air supply module 20a is made relatively flat, i.e. its axial length in this case is much smaller than its width and its height. This special module is the first air supply 20a is made to attach to the outside, is not illustrated fan that creates a flow of air required for the respective heating devices.

In contrast, another first air supply module 20b, and 20c and the second air supply module is provided with a fan 23, which contains, for example, a centrifugal compressor 24 and the fan 25 and the motor.

The fan 23 is set to the first expedient unit 20b feeding air so that its axis of rotation 26 extends substantially perpendicularly to the longitudinal axis 6. In contrast, in the second air supply module 20c expedient fan 23 is set so that its rotation axis 26 extends substantially parallel to the longitudinal axis 6. Accordingly, the first air supply module 20b is provided cubic or spherical shape, wherein a length, width and height are approximately equal. In contrast, in the second air supply module 20c may exercise extremely flat design, in which the length in the axial direction is significantly smaller than the width and height. The motor fan 25 may protrude from the second air supply module 20c corresponding to the hinged second module 15b, and 15c, respectively, in the installed state to enter the corresponding formed in the respective wall-mounted second unit 15b, the cutout 15c. This cutout is indicated in the second position of the implement module 15b 36.

Opposite the main unit 2 axial end side of the air supply modules 20 can be closed with the appropriate cover 27a, 27b and 27c. Moreover, for covering the fan 23 provided with a first air supply module 20b provides 32 additional cover.

After installing base plate 8 on the main unit 2 the axial end portion 3 of the combustion chamber 11 acts in the axial direction of the main unit 2. The fitting 9 with the ignition plugs 10 and the pin is located on this side opposite to the heat exchanger 4, the base plate 8. When installing the respective feed unit 20 the axial air region 11 of combustion chamber 3, 9, respectively socket plugs and the ignition pin 10 includes a corresponding air supply unit 20. For this purpose, the respective air supply unit 20 is provided with at least one corresponding groove. Due to such a structure can perform combustion chamber 3 with a length greater than the length of the respective heat exchanger 4, for example, to realize combustion with the formation of less harmful substances. The corresponding recess in the corresponding module 20 supplying air expedient is a part of the fresh air supply duct inside the module 20, the air supply. Due to this projecting portion of the combustion chamber 11 is located in a zone of relatively intense cold fresh air passage, so that a sufficient cooling of the combustion chamber portion 11. Furthermore, fitting the pin 9 and the ignition plugs 10 are in an area with relatively positive pressure, so that the holder fitting 9, ignition plugs 10 of the pin should not adequately perform additional related costs sealing function.

To install one of the modules 20, the air supply to the main unit 2 is provided first 28 compounds, which ensures bonding together the two modules 2 and 20. In addition, through this space 28 compounds made functional compound both modules 2 and 20 to each other, components, respectively. For example, the module 20 through the air supply to the combustion chamber 3 of the main unit 2 is supplied fresh air. At the outlet from the heat exchanger 4, and the exhaust gases are fed to the appropriate line for the exhaust gases in the unit 20 the supply of fresh air.

To join, ie, for fixing and for the mechanical connection and the individual functional module 15 mounted on the main unit 2, a second connection location 29. Functional compound includes, for example, hinged to the second 15b and 15c of the above connectors modules with which sealingly connected terminals 5 of the heat exchanger 4 second pin 17 mounted modules 15b and 15c.

Also, mounted between the second modules 15b and 15c and the second air supply module 20c holds the third connection 30, through which, for example, the second air supply module 20c is provided with fresh air. The first connection location 28 and the third connection 30 preferably lie in a common plane to facilitate attachment of the second air supply module 20c to the main unit 2 and the second corresponding to the hinged unit 15b respectively, 15c.

Figure 2 illustrates a first basic type of heating device 31 which can be constructed using the modular system 1 according to the invention. Thus the basic module 2 combined with the first one of the modules 20a and 20b and the air supply unit to the first half 15a. 2 shows an embodiment of a built-in fan 23, i.e. combination with the first air supply module 20b.

Shown in this case the heating device 31 is different in length elongated, compact design, the axial length greater than its width and height. This first main type of heating device is particularly suitable for installation in series as an additional heating device. Moreover, from Figure 2 it follows that the opening in the main module 5 fittings assembled, the heat exchanger 4 respectively act on the longitudinal side slots 14 through 35 mounted on the first half 15a of the module and provides it to access outside.

Figures 3 and 4 show different embodiments of the second principal type of heating devices 33, 34 respectively, which can be realized by other combinations of components, respectively, individual modules 2, 15, 20. As shown in Figure 3, to form heating devices 33 connected together the main unit 2, the second module 20c air and the second option (15c) of the second curtain 15b modules 15c. Therefore, this heating device 33 is provided with the fuel pump 19.

In contrast, for the formation of the heating device 34 according to the main module 4 is again combined with the second air supply module 20c, but in this case with the first embodiment (15b) hinged modules 15b, 15c. Accordingly, in this heating device 34 is integrated water pump 18.

The second basic type of heating device in Figures 3 and 4, characterized by its compact design, the height of which corresponds approximately to the axial length, and the height is usually greater than the width of the heating device 33, 34. In particular, the height of the heating device 33, 34 can be selected more than its axial length. Due to this design, the heating device 33, 34 occupies a particularly small volume, thereby the second main type is particularly suitable for implementation as a heating heater, which can be used in very different conditions of installation and for subsequent installation in the engine compartment of the car .

The decisive advantage of the modular system 1 according to the invention consists in that to produce different heating devices 31, 33, 34, which in this case are shown in Figures 2-4, only three different embodiments, the individual modules can be used, in particular basic module 2 for a number of different options, so that manufacturing costs, despite the great variety of options, are relatively small. This is especially true in view of the fact that as used in all variants the same main unit 2 just those integrated components, in particular heat exchanger 4 and the combustion chamber 3, which require relatively high development costs. This ensures a very large number of articles in the party, thereby rapidly amortized the development costs.
