DESCRIPTION OF THE INVENTION

The invention relates to heat engineering, namely to the appliance, and can be used for hot water and space heating for any purpose.

Heating the heat transfer fluid is known (see. Patent RU 2094711, F 24 J 3/00, 27.10.1997 g) containing a liquid chamber provided with supply and discharge pipes of the latter, and a rotor mounted in a chamber fixed to a shaft of perforated discs. The cell further mounted a pair of fixed perforated disk, each of which between the latter to form a gap for passage of fluid set corresponding rotor disk.

The disadvantage of this device is the complexity of the design because of the large number of disks.

It is known to heat the fluid device (see. Application RU 2002113432, F 24 J 3/00, 20.11.2003 city), taken as a prototype. The device consists of a cylindrical body, the stator having a channel inlet opening, outlet opening of the channel, a cylindrical cavity with a gap, and inserted into the rotor cavity formed of multiple disks mounted on a shaft and installed in the stator-housing rotatable by a motor. Disks on the cylindrical surface a plurality of recesses, and peripherally drives in their end faces has a plurality of holes arranged circumferentially and out into the space between the discs intervals.

Disadvantages of the prototype are the following. The chaotic arrangement of through-holes and non-through leads to a lack of control of fluid flow vortex, the possibility of mutual cancellation, which reduces the efficiency of the heating fluid.

The proposed invention solves the problem: reducing energy consumption, increasing the life of the product.

The present invention is directed to the achievement of the technical result is to increase the efficiency teplovyrabotki, improving the mechanical reliability of the device while simplifying design.

Said technical result is achieved in that the device for heating fluid, consisting of a stationary cylindrical body, which is the structure of the actual body and is rigidly associated cap and having an input channel opening outlet passage opening cylindrical cavity within which with clearance is mounted rotatably mounted on the shaft disk with blind holes located on the periphery of its ends on the circumference and the recesses formed on the cylindrical surface of the disc, new is the fact that the inlet channel opening is formed on the center of the lid coaxially with the shaft, and an output channel opening is formed in the cylindrical wall of the housing at an angle in the direction of rotation of the disk, the ends of the disc and the opposing surfaces of the body and the lid are made blind holes having a cylindrical surface with no chamfers and rounding and arranged circumferentially in the form of radial rows, each row of holes on the disc is finished groove in the form of semicircle of identical blind holes, the device is provided with a mechanical seal relative to the housing, disposed in a chamber having an outlet in a cylindrical cavity of the body, symmetrically outlet relative to the device axis an opening connected via a further hydraulic channel with the chamber face seal disc of cylindrical surfaces are the disc mounted in a cylindrical cavity with a minimum gap.

The minimum clearance is made equal to 0.3-1.0 mm.

To ensure the vaporization process, the output is set with the throttle hole having a much smaller size than the outlet opening of the channel.

Placing the input channel on the shaft center of the hole allows, firstly, to maximize the path of the fluid under pressure and the action of increasing centrifugal force from the shaft to the outlet opening, thereby to increase the fluid friction area of ​​the disc surface and a housing with a lid, and therefore increase the effectiveness of heating the liquid.

Secondly, with this arrangement, the input and output apertures there channels effect "forcing" the liquid, which allows the presence of the centrifugal forces in the region to maintain a gap between the cylindrical wall of the housing and the cylindrical drive surface pressure of 0.1-0.5 MPa (depending on diameter disc) required for the emergence in the areas of blind holes cavitation processes that work together with the forces of friction leads to a significant increase in thermal performance.

Thirdly, the introduction of fluid into the device at the center of the shaft, i.e. in the zone of the greatest dilution of the coolant acting on the centrifugal force provided by fluid pumping through the device without increasing the pressure at the inlet.

Placing output channel openings on the cylindrical wall of the housing at an angle with the direction of disk rotation can remove the heated liquid through a channel having a lower hydraulic resistance, which reduces power consumption and hence improves the efficiency of heat generation. Placing the ends of the disc and the opposing surfaces of the body and cover in the form of blind holes radial rows spaced circumferentially stimulating effect allows fluid friction between the rotating disk and the fixed body and the cover, and when executed in a cylindrical surface shape with 1.5 mm recess ( depending on the size of the disc-body and hence, depending on power), also allows to create a zone of cavitation these holes, resulting in the release of a large amount of heat. Moreover, the imposition on the edge chamfers and rounding holes invalid because it dramatically reduces the efficiency of heat and there is no point in fact, because the operation of the device after a certain period of use due to the artificially created friction within its processes and cavitation occurs blunting of edges.

An important role for promoting cavitation processes and friction, and consequently to increase teplovyrabotki has the value of the gap between housing and cover plate. When the gap of more than 1.0 mm the effect of heat drops sharply as the pressure inevitably falls inside the unit, the friction processes are less intense, and the process of cavitation disappears altogether. Therefore, the most preferred is 0.5 mm gap. Performing zaaora less than 0.5 mm requires design complexity, greater precision fabrication of hull and rotating parts. This is unacceptable reduced consumption of liquid pumped through the device.

Radial rows of blind holes on the drive end at the edge of the end grooves in the form of semicircles, that allows to intensify the processes of friction and cavitation on the edges of the disc. Deepening the groove is made in accordance with the deepening of blind holes. After passing the cooled zone semicircles its direction changed by 90 °, and the processes of cavitation and friction occur between the cylindrical surface of the housing and the cylindrical surface in the disc placed on the surface of blind holes, which are identical to the openings at the end.

A supplemental channel for circulating the working fluid connecting hole symmetrical output channel opening, with a camera for installation of the mechanical seal, plays an important role. Firstly, the liquid circulates through it in order to provide cooling (washing) seal. Secondly, the liquid moves along the contour in the direction from the high pressure region (cylindrical part of the housing) to the dilution region (chamber for compacting, as close to the shaft), and then moves between the drive end and the housing being subjected to the same influences of frictional forces and cavitation that on the opposite side of the disc. At the same time there is a significant pressure equalization on both sides of the rotating disk, which favorably affects the operational and mechanical properties of the device. The efficiency of heat increases as involving two circuit passing coolant, ensures maximum device load.

At minimum, this refinement outlet for a liquid heating apparatus can be operated in a steam generator mode. Completion is set to throttle output with a hole having a much smaller size than the outlet opening of the channel. By reducing the flow of the pumped fluid will inevitably begin the process of vaporization.

Technical solutions with the features distinguishing the claimed solution from the prototype, and not clearly known from the prior art do not follow. This suggests that the claimed solution is new and inventive.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a device for heating fluid circuit in Figure 2 - arrangement of blind holes and grooves on the disc in Figure 3 - a schematic of the throttle 4 - view A in Fig. 1.

DEVICE FOR HEATING FLUID

Device for heating liquids comprising a cylindrical housing 1 rigidly connected with it the cover 2, opening 3 of the input channel, output channel opening 4 and a cylindrical drive cavity 5. Inside the cavity 6, a cylindrical body and a cover rotatably with a minimum gap of 0.5 mm shaft 7, the shaft is fixed in the bearing support and the sleeve through the resilient member 8 is connected to the motor 9. The clearance of 0.5 mm is in the range 0.3-1.0 mm. Since achieve high manufacturing accuracy is not always possible, the possible slight misalignment disk, resulting in the periphery of the disc gap can be formed between it and the housing or between the lid and about 0.3 mm, which is taken as the lower limit of the selected range 0 3-1,0 mm. Input channel hole 3 holds the middle cover 2 coaxially with the shaft 5 and an output channel opening is formed in the cylindrical wall of the housing 1 at an angle in the direction of rotation of the disk 6. At the ends the disc and opposing surfaces of the housing 1 and cover 2 are blind holes 10 having a shape cylindrical surface without chamfers and rounding and arranged circumferentially in the form of radial rows, each row of holes on the disc 6 is completed in a groove 11 semicircular. The holes on the cylindrical surface of a disk identical blind holes 10. All the blind holes 10 and slots 11 are formed with a diameter and a depth selected in the range of 1-5 mm. Symmetrical opening 4 output channel with respect to the axis of the device is a hole 12 which is connected via an additional channel with a hydraulic chamber 13 of the mechanical seal 14. The opening 4 channel output can be installed throttle 15 required to form the vaporization process. The hole in the inductor 15 has a much smaller size than the opening 4 of the output channel.

Device operates as follows

Through Hole 3 input channel under pressure from the lid 2 on the center shaft 7 is fed liquid. After filling the device with liquid turns the motor 9. By coupling with the elastic member 8 is transmitted to the rotation shaft 7. The rotation rate of 3000 rev / min. Disc 6 mounted on the shaft 7 rotates at the same speed. The coolant, which is attached to the inlet pressure under the action of centrifugal force moves the disk between the end cap 6 and 2. The zones of blind holes 10 having high friction effect and cavitation field that causes the heating fluid. Upon reaching the cylindrical surface of the housing direction of flow is changed by 90 °. Here, the liquid is subjected to cavitation and heating due to friction heat blind holes located on the cylindrical surface of the disc 6 and the slots 11 in the form of semicircles at the ends of the disk. Then partially heated fluid tends to channel outlet opening 4, opening 12 in the partially connected to the chamber 13 of the mechanical seal 14. After passing the mechanical seal chamber, directs the coolant through the gap between the housing 1 and the disk 6, incurring cavitation impact and friction effects described above. The total flow of the heated liquid from the opening area 4 output channel, that is, from the high pressure zone is supplied to the heating system or hot water.

The relationship between the consumption of electricity and thermal energy released by the device above the unit, which makes advantageous use of the present invention.
