Description

[Detailed explanation of the invention] <Industrial application> This invention heats the interior of houses in cold regions by placing each side edge on an adjacent joist and fixing the floor finishing material on top of it. This invention relates to a heat dissipation unit for floor heating that heats the floor with hot water obtained using exhaust heat from a heater.

<Conventional technology> Such a heat dissipation unit for floor heating was disclosed in Japanese Patent Application Laid-Open No. 1983-
No. 124879 discloses a method in which a thin metal plate, for example a thin copper plate, is provided with an Ω-shaped cross-sectional groove protruding from the lower surface in the longitudinal direction of the metal plate, and a metal hot water pipe is inserted into the Ω-shaped cross-sectional groove. It is maintained through.

The thin copper plates used are approximately 0.2 to 0.3 mm thick, the width is slightly larger than the spacing between the joists, and is usually around 40 cm, and the length can reach approximately 3.6 mm.

<Problems to be solved by the invention> In the above conventional example, both sides of the thin metal plate are fixed on adjacent joists, and the spacing between the joists is adjusted to prevent the temperature of the hot water flowing through the pipe from decreasing. The bottom surface is covered with a board, and an insulating material such as glass wool is loaded between the thin metal plate, but it is very time-consuming to install, and during use, moisture in the space where the glass wool is loaded condenses, causing the glass wool to deteriorate. As a result, the glass wool becomes flattened and loses its insulating properties, and loses its ability to keep the hot water flowing through the pipes warm.

Furthermore, the thin metal plate through which the hot water pipe is held is large and bends easily, making it difficult to handle.

<Means for solving the problem> Therefore, in the heat dissipation unit for floor heating of the present invention, a hard foam layer is bonded to the bottom surface of the thin metal plate, leaving both sides of the plate, and at least one side of the hard foam layer is bonded to the bottom surface of the thin metal plate. It is characterized by having a compressible elastic layer attached.

<Function> The thin metal plate that holds the water pipe through it has a hard foam layer bonded to its lower surface, leaving both sides intact, so it is reinforced by this hard foam layer and does not bend easily.

Furthermore, construction can be carried out by compressing the soft foam layers attached to both sides of the hard foam layer and inserting them between the joists from above.

<Example> In the illustrated example, 1 is a thin copper plate, 2 is two Ω-shaped cross-sectional grooves that bulge out from the lower surface parallel to the side edges at a distance of about 15 cm from each side edge to be placed on the joists, and 3 is the above-mentioned groove. A copper hot water pipe is shown penetrated and held in each Ω-shaped cross-sectional groove 2.

Each hot water pipe 3 is fixed in the Ω-shaped cross-sectional groove 2 by brazing so that its upper surface is flush with the upper surface of the thin copper plate 1, and the tape 4 is attached to both sides of each Ω-shaped cross-sectional groove. ', 2' and the top surface of the hot water pipe 3, and is pasted along the hot water pipe.

The tape 4 may be an aluminum foil adhesive tape or a paper adhesive tape. In the case of aluminum foil adhesive tape, for example, 40 cm long aluminum foil tape is applied discontinuously in the longitudinal direction of the thin copper plate as shown in Figure 1.
Paste at a distance of 10 cm. In addition, in the case of paper adhesive tape, it may be applied in series in the longitudinal direction of the thin copper plate.

It is preferable that each end of the hot water pipe 3 protrudes a little from the front and rear ends of the thin copper plate 1 to facilitate connecting U-shaped pipes so that adjacent pipes form a meandering or other flow path.

In order to prevent the temperature of the hot water flowing through the hot water pipe 3 from decreasing,
A hard foam layer 5 is placed on the bottom surface of the thin copper plate 1, leaving both sides intact.
In this embodiment, a compressible elastic layer 6 is attached to each side of the rigid foam layer 5. For example, the hard foam layer 5 is a flame-retardant hard urethane foam with a foaming ratio of about 50 times, and the compressible elastic layer 6 is a foaming ratio of about 50 times.
It may be made of soft urethane foam that is 100 times stronger or more, or natural or synthetic rubber.If it is not flame retardant, it should be coated with fire retardant paint or mixed with a flame retardant treatment.

The hard foam layer 5 is formed to have a groove on its upper surface into which the Ω-shaped cross-sectional groove 2 can be fitted, and the Ω-shaped cross-sectional groove is fitted into the groove and bonded to the lower surface of the thin metal plate 1 by adhesive. Alternatively, the lower surface of the thin metal plate may be made a part of a foam mold, and the thin metal plate may be directly foam-molded and bonded to the lower surface of the plate.

This hard foam layer 5 also has the role of reinforcing the thin copper plate 1, so that the thin copper plate does not bend or bend, making it extremely easy to handle.

Then, for construction, the compressible elastic layers 6, 6 attached to both sides of the hard foam layer 5 are compressed as shown in FIG. Both sides 1' of the thin copper plate 1,
1' is fixed by nailing onto the joist, and the floor board 8 is placed on top of it. Even if there is some dimensional variation in the spacing between the joists 7, 7, the compressible elastic layer 6 allows the joists 7, 7 to be fitted without any problem.

In this way, the construction is extremely easy because it is possible to close the space between the bottom surfaces of the joists with a board and do not fill it with a heat insulating material such as glass wool.

Incidentally, if necessary, glass wool 8 or the like may be filled between the joists and under the unit.

If glass wool is not filled, hard foam layer 5
The thickness is about 20 to 30 mm, and when filled, it is about 10 to 15 mm.

Further, the compressible elastic layer 6 does not need to be attached to both sides of the hard foam layer 5, and may be attached only to one side.

<Effects of the Invention> According to the present invention, it is possible to provide a heat dissipation unit for floor heating that is reinforced with a hard foam layer, has heat insulation properties, and is easy to handle and install.
