In a second variant, the above-described heating system further comprises a first diffusing element disposed at one place in the first row of cavities in such a manner that the fluid that rushes in the first direction after striking against the first supporting element hits it first and the second diffusing An element located in one place in the second row of cavities so that the fluid that rushes in the second direction after striking against the first supporting element hits it first. In the third embodiment, the above-described heating system further comprises two guide channels that are located in those diametrically opposite corner areas where there are no flow pipes and which connect the upper and lower plates and have a predetermined width and length in the first and second directions. The technical result of the invention is the creation of a heating system in which the heating fluid is distributed uniformly.

DESCRIPTION OF THE INVENTION

The present invention relates to a heating system in which plate-shaped heating panels are used. In particular, the present invention relates to a heating system using plate heating panels having cavities between the upper and lower plates, and the heating process itself is performed by the flow of heating fluid through said cavities.

Traditionally used in homes, the heating system has a design that uses pipes laid in a layer of foam concrete, placed on a concrete floor. A heating fluid, for example hot water, is supplied through said pipes for heating purposes. However, it is expected to increase the use of prefabricated heating systems comprising plate heating panels that can be connected to each other and within which there is a cavity through which the fluid flows. Compared with the pipe structure, the panel structure is easier to manufacture and repair, while it provides better heat output, since there is no loss of heat through the concrete.

US Pat. No. 5,088,166 for this design with heating panels describes a plate-shaped heating element comprising spacers that are disposed between the upper and lower plates and which resist the forces acting on this heating element when it is used to heat the floor. These spacers are arranged in a particularly preferred manner.

However, according to the results of the model tests performed by the present author, it has been found that after the flow of the heating fluid has been given a certain direction, said fluid is distributed unevenly in this heating element. This is the result of the fact that the cavities between the spacers are connected to each other in one specific direction throughout the heating element.

In addition, fluid connections (hereinafter flow pipes) are provided at diametrically opposite corners of the heating element through which the heating fluid is supplied to and removed from each of said heating elements. However, in the other two corners (i.e., at the corners where these nozzles are not present), the flow rate of the heating fluid decreases.

Consequently, the heating fluid does not flow freely through the corners, where there are no flow pipes, and thus the temperature of these zones is reduced. In the heating element, bubbles can form due to turbulence in the corners, and then a smooth flow of the heating fluid can not be ensured. The result of these problems is that the heat spreads non-uniformly and the heat output decreases.

SUMMARY OF THE INVENTION

One object of the present invention is to provide plate-like heating panels in which the supplied heating fluid is distributed uniformly.

It is another object of the present invention to provide plate heating panels in which the flow rate of the heating fluid in those corners where there are no flow nozzles is increased to thereby prevent the fluid from accumulating at these corners.

It is another object of the present invention to provide a heating system using a coupling device for connecting heating panels and their cavities so that the heating fluid can flow sequentially through said panels.

To achieve the above objects, the present invention provides a heating system including heating panels, each of which includes a substantially rectangular upper and lower plate mounted opposite one another to form cavities therebetween, supporting elements that are designed to connect the top and bottom plates and each of Which has a predetermined area and is located at a distance from adjacent support elements, and two flow nozzles installed at two diametrically opposite corners of the upper and lower plates and connecting elements intended for connecting the flow pipes of adjacent heating panels to ensure a continuous flow of heating fluid through the heating Panel. Said supporting elements are uniformly arranged in a first direction parallel to the long side of the upper and lower plates and in a second direction parallel to the short side of said plates thereby forming the first and second rows of cavities corresponding to said first and second directions and the heating system comprises at least At least one scattering element located in one place in the first and second rows of cavities opposite the corresponding flow nozzle and carrying out the dissipation of the heating fluid.

Preferably, the supporting elements are evenly spaced along the central axis of the flow nozzles at a predetermined distance from them and include a first support element closest to one of said nozzles. The scattering element is located where the heating fluid is dissipated by the first supporting element.

Preferably, the scattering element includes a first diffusing element disposed at one location in the first row of cavities such that a fluid that rushes in the first direction after striking against the first supporting member hits it primarily, and a second diffusing element located in one place In the second row of cavities, so that the fluid that rushes in the second direction after striking against the first supporting element hits it first.

Preferably, each of the supporting and scattering members is formed by two concave zones that are located in the respective zones of the upper and lower plates and which are concave so that these areas of the upper and lower plates touch each other to thereby form a corresponding supporting or scattering member.

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

1 is a top plan view of a heating system according to a preferred embodiment of the present invention, and FIG. 2 is an enlarged view of the connector element shown in FIG.

The heating system includes heating panels 2 having an internal space, i.e. cavities (not shown in the figures), through which the heating fluid flows, and connecting elements 4 intended to connect said panels 2 to a single unit, thereby creating flow-through Of the paths between these panels 2. Preferably, each heating panel 2 is made of a thermoplastic material, so that it is easier to manufacture and easier to mold than conventional designs of metal pipes. The heating panels 2 are provided with a plate-like shape, so that the heating fluid flowing inside them heats a large area of ​​the floor (or wall or ceiling).

In a preferred embodiment of the present invention, the heating panels 2 are rectangular and have long and short sides. Each panel 2 at two diametrically opposite corners is provided with two flow connection connections 6. Through the said nozzles 6, the heating medium is supplied and discharged. The heating panels 2 are arranged to form a continuous structure, and the flow nozzles 6 of the adjacent panels 2 are connected in a common area. The connecting elements 4 connect the two nozzles 6 of the adjacent heating panels 2 to each other.

As shown in FIG. 2, each connecting member 4 comprises a central connection tube 8 and two elbows 10 installed at opposite ends of this tube 8. The inner diameter of said elbows 10 is somewhat larger than the outer diameter of the connection tube 8 and the flow nozzles 6 of the heating panels 2, and During assembly, these knees 10 are put with some force onto the tube 8 and the nozzles 6 with a set distance thereon. The legs 10 are made of the same thermoplastic material as the heating panels 2, so that during the assembly of the heating system, they are connected to these panels by means of a thermal melting process in the position at which they cover the flow nozzles 6 to form a single unit therewith.

With this design of the heating system, the heating fluid supplied to its inlet passes successively through the heating panels 2 through the connecting elements 4 and is then discharged from the system through its outlet. The flow direction of the heating fluid is indicated by the dotted arrows in FIG.

In such a prefabricated heating system, it is of utmost importance that each heating panel 2 provides a smooth flow of the heating fluid, and not at the expense of the characteristics determining the thermal efficiency, and with preventing the accumulation of the heating fluid in certain areas. By fulfilling these conditions, uniform heat distribution through the panels 2 is maintained.

3 is a perspective view of a heating panel according to a first preferred embodiment of the present invention. FIG. 4 is an enlarged view of a portion of the heating panel shown in FIG. 3, and FIG. 5 is a cross-sectional view along line AA in FIG.

In the drawings, it can be seen that the heating panel 2 includes an upper plate 14 and a lower plate 16 facing one another to form internal cavities 12, supporting elements 18 having a predetermined area and spaced from each other by predetermined distances, and two flow nozzles 6.

Preferably, each support member 18 is formed by a pair of concave zones 20, namely the zones 20 constituting each of said pairs are located in the respective zones of the upper plate 14 and the lower plate 16 and are concave so that these zones of the upper 14 and lower 16 plates contact each other Thereby forming a corresponding supporting member 18.

The support elements 18 prevent deformation of the upper and lower plates 14 and 16 under the influence of external forces and lead to the formation of cavities 12 through which the heating fluid flows, namely the cavities 12 are formed between the support members 18. As a result, the heating fluid supplied through one From the two flow nozzles 6, flows through the cavities 12 between the upper and lower plates 14 and 16, thereby transferring the heat to the outside of the upper plate 14, as indicated by the dotted arrows in FIG.

The supporting elements 18 and resist the flow of the heating fluid, whereby it is evenly distributed within the heating panel 2. The flow of the heating fluid supplied to the panel 2 is greatly influenced by the dimensions of the supporting elements 18, the distance between these elements and the order of their location.

In a preferred embodiment of the present invention, the support members 18 are formed by concave zones 20 having a substantially cylindrical shape of a certain diameter and arranged at predetermined intervals both in the horizontal direction (x direction in FIG. 3) and in the vertical direction (y direction in FIG. 3). Preferably, the distances D1 and D2 between the supporting members 18, respectively, in the horizontal and vertical directions, and the diameter D of the concave zones 20 forming the said elements 18 are the same.

The central axis of each of the flow nozzles 6 through which the heating fluid is supplied and removed is located at substantially an angle of 45 ° to both the long and short sides of the upper and lower plates 14 and 16 forming an angle where there is one particular spout 6 Therefore, the heating fluid supplied through one of the nozzles 6 is distributed by the supporting elements 18, moving along the heating panel 2.

In a preferred embodiment of the present invention, in contrast to the flow nozzles 6, scatter elements are arranged to disperse the fluid. 6 and 7 show an enlarged view of a part of the heating panel shown in FIG. In order to distinguish the support elements 18 and the diffusing elements 22 and 24 from the cavities 12, these elements 18, 22 and 24 in these figures are shaded.

Preferably, each scattering element 22 and 24 is formed by two concave zones 20 in the same way as the support elements 18.

Since the support elements 18 are uniformly spaced in the horizontal and vertical directions at predetermined distances, the cavities 12 extend continuously in said horizontal and vertical directions opposite the nozzles 6.

The first diffuser element 22 is positioned opposite the flow nozzle 6 at one location in the first row of cavities which extends horizontally and whose axis is shown by line D and the second diffusing element 24 is positioned opposite said nozzle 6 at one location in the second row of cavities that extends into The vertical axis and the axis of which is shown by the line E.

In addition, the center of the first diffusing element 22 is not in line with the other supporting elements 18 in the horizontal direction, and the center of the second diffusing element 24 is not in line with the other supporting elements 18 in the vertical direction.

Therefore, the first diffuser element 22 is disposed so that the first row of cavities (line D in the drawings) does not extend directly to the flow tube 6, and the second diffusing element 24 is positioned so that the second row of cavities (line E in the drawing) To said nozzle 6, thereby dissipating the heating fluid accumulated in these cavities.

In more detail, the support elements 18 are uniformly arranged in the horizontal and vertical directions (x and y directions) of the heating panel 2, and along the central axis (the z-direction in the drawing) of the flow tube 6. Between the supporting elements 18 located along the central axis of the flow Nozzle 6, in places where the flow of the heating fluid is separated by the first supporting element 26, there are first and second diffusing elements 22 and 24 (if the first support member 26 accepts the one closest to the nozzle 6).

That is, the first diffusing element 22 is located at one point in the first row of cavities (line D in the drawing) in such a way that the fluid striking horizontally after striking against the first support member 26 hits it first. The second diffusing element 24 is located at one point in the second row of cavities (line E in the drawing) in such a way that the fluid striking vertically after striking against the first support member 26 hits it first.

The relative arrangement of the first support member 26 and the first and second diffusers 22 and 24 is described in more detail with reference to FIG. A line that is tangent to both the first supporting element 26 and the first scattering element 22 (dashed line B in the drawing) is parallel to the horizontal direction, and the line that is tangent to both the first support element 26 and the second scattering element 24 ( The dotted line C in the drawing) is parallel to the vertical direction. These two tangents intersect at a right angle at a point in the immediate vicinity of the first support member 26 and slightly offset in the direction of the flow tube 6.

7, it can be seen that due to this construction of the heating panel 2, the heating fluid within this panel flows along the central axis of the flow nozzle 6 and first hits the first supporting member 26. Consequently, the flow of said medium deviates in the horizontal and vertical directions.

The fluid striking in the horizontal direction is again deflected up and down (see the drawing) by the first diffusing element 22, bending around it, and thus its flow moving in the horizontal direction is dissipated. The fluid that rushes vertically after striking against the first support member 26 again deviates left and right (see the drawing) by the second diffusing element 24, bending around it, and thus its flow moving in the vertical direction is dissipated. Thereafter, the fluid stream separated by the first and second diffusing elements 22 and 24 is repeatedly divided by support elements 18 disposed in the horizontal and vertical directions.

With the internal structure of the heating panel 2 described above, the flow of the heating fluid is first deflected by the first supporting element 26 and then again dissipated in the horizontal and vertical directions, respectively, by the first and second diffusing elements 22 and 24. Consequently, the heating fluid supplied through the flow tube 6, More evenly distributed inside the heating panel 2.

In addition to the first and second diffusers 22 and 24 located in the areas opposite the flow nozzles 6 as described above, the proposed heating panel 2 can also include guide channels located at those two corners where flow nozzles 6 are absent.

FIG. 8 is a top view of a heating panel according to a second preferred embodiment of the present invention, and FIG. 9 is an enlarged view of a portion of the heating panel shown in FIG. The heating panel 2 'includes first and second guide channels 28 and 30 disposed in those corner areas where flow nozzles 6 are not present.

Each guide channel 28 and 30, the first and second, is formed by two concave zones located in the respective zones of the upper plate 14 and the bottom plate 16 and recessed so that they come into contact with one another thereby forming the respective said channels 28 and 30. The first and second The second guide channels 28 and 30 are at a predetermined distance from the corners of the heating panel 2 'and have a predetermined width and length in the horizontal and vertical directions.

Preferably, said channels 28 and 30 have a width W substantially equal to the diameter D of the supporting members 18 and a length L in the horizontal and vertical directions comparable to the extent of the space occupied by the three to five supporting members 18 (i.e., the length L greater than the diameter D support elements 18 approximately six to ten times).

The first and second guide channels 28 and 30 reduce the resistance to the flow of the heating fluid in those corners of the heating panel 2 ', where they are located, thereby increasing the flow rate of this medium. These channels 28 and 30 and direct the heating fluid to the zone where it leaves the heating panel 2 '. Therefore, the heating panel 2 'including the first and second guide channels 28 and 30 prevents the heating fluid from accumulating in the corners and the occurrence of bubbles due to turbulence. This allows for a more even distribution of heat throughout the heating panel 2 '.

Preferably, the ratio of the dimensions of the long and short sides of the rectangular heating panels 2 is in the range of from 1.5: 1 to 3: 1. Such dimensions are necessary for the following reason. Since the central axes of the flow nozzles 6 are arranged at an angle of 45 ° to the respective adjacent sides of the heating panel 2, in the case that said panel 2 has a square shape, i.e. in the form of a regular square, the flow of fluid from two diagonally opposite flow nozzles 6 Of each heating panel 2 will converge approximately at the center of said panels 2. This will result in an uneven distribution of the heating fluid within the panels 2.

Referring to FIGS. 10 and 11, it should be noted that the heating panel 2 "can be in the form of a polygon, i.e., a five- or an octagon, in addition to the rectangular shape described above, which makes it easier to achieve a continuous arrangement of the heating panels 2" when assembling the heating system.

FIG. 12 shows one of the above-described heating panels 2, which has an insulation layer 32 disposed below the lower plate 16 and made, for example, of expanded polystyrene. This simplifies the process of laying the heating panels 2 on the floor of the building, apartment, etc. The insulation layer 32 and minimizes the heat loss from the heating panel 2 and compensates for the difference in height of the flow nozzles 6 with respect to the upper and lower plates 14 and 16.

The heating fluid that is supplied to the heating panels according to the present invention and having supporting and diffusing elements and guide channels is distributed more evenly, and thus a more uniform heat distribution over the entire surface of said heating panels is achieved. In addition, the heating fluid flows throughout the interior of said panels more smoothly, as a result of which the heat transfer efficiency increases.

While the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that numerous changes and / or modifications may be made to the basic concepts set forth in this application by the person skilled in the art without departing from the scope of the invention as set forth in the appended claims.
