Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a heat exchange panel used in a hot water circulation floor heating system, other heating devices, etc. (Background Art) A heat exchange panel is usually used in a heat medium circulation system, etc. A heat exchange panel performs heating by passing a heat medium such as hot water sent from a heat medium circulation device through the panel and exchanging heat.

In conventional heat exchange panels, upper and lower woven fabrics are arranged so that a space is formed between them through which a heat medium can flow through filaments sewn together, and a watertight resin layer is polymerized on the outer surface of each of these woven fabrics. A panel body was formed. The space through which the heat medium flows is formed by a flow path through which the heat medium circulates. Conventionally, when forming the flow path, a member of the same quality as the resin layer is applied to the necessary parts of the panel body, and these parts are compressed with a heat press, thereby crushing the woven fabric inside the panel and allowing the flow to flow. It formed a barrier between roads. However, the boundaries between the flow channels have been reinforced by sewing to withstand pressure against heat presses. When reinforcing this, there is a problem in that since the distance between the flow paths is quite long, a special sewing machine with deep pockets to accommodate the length is required. In addition, as the woven fabric inside the panel comes into contact with the heat medium,
A material with good heat resistance is used. Therefore, since the woven fabrics do not weld to each other, when forming the barrier between the flow channels, it is necessary to weld the outer resin layers together through the woven fabric. It was difficult to form a barrier.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a heat exchange panel in which a flow path for a heat medium is easily formed and the heat medium does not leak out of the flow path.

[Disclosure of the invention]

In order to achieve the above object, the inventors conducted extensive studies and completed this invention.

This invention creates a space in which a heat medium flows between upper and lower woven fabrics by means of filaments sewn between them.

) Q! It is a heat exchange panel in which a watertight resin layer is polymerized on the outside to form a panel body, and the periphery of the space is sealed with a peripheral sealing material, and the panel body is divided into several parts. The gist of the heat exchange panel is a heat exchange panel characterized in that a cross-section sealing material that joins cross-sections forms a flow path for a heat medium. Hereinafter, an embodiment thereof will be explained in detail based on the accompanying drawings.

As shown in FIG. 1, the inside of the panel body 1 is formed into a space 2 through which a heat medium flows. The periphery of this space 2 is sealed with a surrounding sealing material 3.

The panel main body 1 is divided into two parts, and a cross-sectional sealing material 4 having a square cross-section that joins the divided cross-sections serves as a boundary between a space 2 and a flow path for a heat medium. That is, the cross-section sealing material 4 is made of thermoplastic resin, and after the panel main body 1 is inserted into the recess, it is welded between the cross-sections so that both ends of the cross-sections remain as flow paths for the heat medium. . Both ends between the cross sections are enclosed by enclosing members 5a and 5b so as to cover the cross sections from both upper and lower sides. One enclosing member 5a is provided with an inflow nozzle 6a and an outflow nozzle 6b for the heat medium, each of which communicates with the space 2 of the panel body 1. The heat medium entering from the inflow nozzle 6a follows a flow path like an arrow and flows out from the outflow nozzle 6b. Heat exchange takes place during the circulation.

Next, another embodiment of the heat exchange panel according to the present invention will be described based on FIG. As shown in this figure, the inside of the panel body 11 is formed into a space 12 through which a heat medium flows. A peripheral sealing material 13 made of thermoplastic resin and having a U-shaped cross section is fitted around the space 12. The panel body 11 is divided into two parts, and a cross-section sealing material 14.14 made of the same shape and material as the surrounding sealing material 13 is fitted to each divided cross-section so as to leave both ends between the cross-sections. has been done. In this state, the two separate cross-sectional sealing materials 14 and 14 are butted together in the direction of the arrow,
It is hot pressed at the same time as the surrounding sealing material 13. This results in
The cross-sectional sealing material, which was originally separate, is welded and integrated by heat pressing, and the integrated cross-sectional sealing material joins the separated cross-sections of the panel body. Furthermore, this cross-section sealing material is welded to each cross-section of the panel body, thereby forming a heat medium flow path. On the other hand, the peripheral sealing material reliably seals the periphery of the space in the heat exchange panel by heat pressing. The enclosing member shown in FIG. 1 is used for enclosing both ends of the cross section. However, the shape of the enclosing member is not limited to this.

Inside the heat exchange panel, as shown in FIG. 3, upper and lower woven fabrics 7.7 are arranged so as to form a space 12 between them through which a heat medium can flow, by means of filaments 8 stitched therebetween. A watertight resin layer 9.9 is polymerized on each outer surface of these woven fabrics 7.7 to form a panel body 11. In the figure, 13 is a peripheral sealing material, and 14 is a cross-sectional sealing material. The structure of the heat exchange panel mentioned as the first example is also
It is the same as above.

If the cross-section sealing material is used to close the cross-section, the heat medium will not penetrate into other flow paths through the cross-section sealant, that is, the heat medium will not leak out of the flow path. In addition, the heat exchanger according to the present invention can easily form a flow path for the heat medium by simply joining the cross sections of the panel by a method such as welding with a cross-section sealing material, without going through the laborious work of sewing. As the cross-sectional sealing material constituting the panel, thermoplastic resin such as vinyl chloride is used, for example. However, it is not limited to this.

The cross-sectional sealing material and the surrounding sealing material may be made of different materials. Moreover, it is not particularly necessary that both be hot-pressed at the same time.

There are no particular restrictions on the divided shape of the panel body. For example, as shown in FIG. 4, the panel body 11 may be divided approximately diagonally. In the figure, 14 is a cross-sectional sealing material. Further, it may be divided into three or more pieces.

There are no particular restrictions on the shape of the cross-sectional sealing material. For example, the fifth
15. A butt structure made by interlocking machining as shown in figure + al. In the same figure [21. The same figure (as seen in BL, a member 1 having a convex portion 19 that serves as a barrier between a flat plate member 17 and a flow path.
8 and 16. It is also possible to use a piece 20 that is integrally molded into an engineering shape from the beginning as shown in FIG. 1cI. Note that the cross-section sealing materials that are separate between the panel cross-sections do not necessarily need to be integrated by welding.

〔Effect of the invention〕

As described above, in the heat exchange panel according to the present invention, the upper and lower woven fabrics are arranged so as to form a space between them through which a heat medium flows due to the filaments sewn between them, and each outer surface of these woven fabrics is watertight. A heat exchange panel in which a resin layer is polymerized to form a panel body, and the periphery of the space is sealed with a peripheral sealing material, and a cross section that joins the sections of the panel body that are divided into several parts. The sealing material is characterized by a gap that forms a flow path for the heat medium, so the gap blocks the heat medium from entering, and the heat medium leaks out of the flow path through the gap. The effect is that nothing happens. In addition, the flow path for the heat medium can be formed simply by sealing the cross sections of the panel body with the cross section sealing material, so the effect that the flow path can be formed is very simple.
