Description

[Detailed Description of the Invention] The present invention relates to a so-called floor heating panel that heats a room from the floor by flowing a heat medium such as hot water through circular pipes arranged in a meandering manner on the floor.

In general, in addition to its original heat dissipation performance as a heating device, floor heating panels must also have the floor load strength as a structural material because they are used on the floor. It must also function as a heat insulating layer to prevent heat leakage.However, highly durable heat insulating materials have relatively high thermal conductivity, making them insufficient as a heat insulating layer; conversely, materials with excellent heat insulating performance have low compressive strength. It has the characteristic of being inferior.

In view of these issues, the present invention provides a floor heating panel that has excellent heat insulation properties and improved strength against floor loads.

Conventionally, as this type of floor heating panel, those shown in FIGS. 1 and 2 have been proposed.

That is, the cross-sectional shape is bent into an L-shape in advance to form a heat dissipation plate 1 consisting of a long side 2, a flat part 4, and a short side 5, and a plurality of through holes 3 are provided in the long side 2 at predetermined intervals. , and the flat parts 4 of these heat sinks are arranged one after another so that they are lined up in the same direction as shown in FIG. This is a heating panel formed by joining shaped bends 7 and filling a space 8 formed by the flat part 4 and the long side part 2 with a heat insulating material.

In such a structure, the heat exchanger tube 6 inserted into the through hole 3 is expanded mechanically or hydraulically, and the heat sink 1 is expanded.
Excellent heat dissipation ability can be obtained by making the heat dissipation plate in close contact with the heat dissipation plate and by forming the heat dissipation plate from a metal with excellent thermal conductivity such as copper or aluminum.

In addition, in this configuration, since the long side part 2 of the heat sink is formed perpendicular to the floor surface, the long side part also serves as a structure that supports the floor load, and has superior compressive strength compared to conventional floor heating panels. It is something that has.

However, although this conventional floor heating panel had excellent durability against the load C on the long side opposing portion, the strength against the load on the short side was relatively low.

This is because the ends of the short sides sink into the heat insulating layer, and this was particularly noticeable when the heat insulating material was soft.

This invention was made to eliminate the above-mentioned drawbacks, and one embodiment of this invention will be described above with reference to FIGS. 3 and 4.

In the present invention, as shown in FIG. 3, the long side 2 of the heat dissipation plate 1 is bent in a stepped manner from the flat part 4 to the short side 5 at a height B that is approximately equal to the thickness A of the heat dissipation plate. A portion 9 is provided, and this long side portion 2 is formed by 2a and 2b.

When combining these, the short side 5 of the adjacent heat sink
The heat exchange element 10 is constructed by arranging the flat portions of the heat sinks so that they are aligned in the same direction so that they are in contact with the long side portions 2b.

Note that FIG. 4 shows the above heat exchange element in cross section taken along line IVIV in FIG. Supports loads.

In this way, in the present invention, since the load on the short side is supported by the adjacent long side, the compressive strength can be dramatically improved compared to conventional floor heating panels.

Therefore, no heat insulating material (filling material) is required at all in the space formed by the long sides and the flat part, or even an extremely soft heat insulating material is sufficient for strength.

Furthermore, if this space is defined as an air layer, air convection within the panel,
Radiation heat transfer occurs and heat dissipation characteristics can be improved.

However, in this case, it is necessary to take measures such as laying floor panels on insulation boards to reduce heat leakage to the underfloor area.

Note that FIG. 4 shows an embodiment in which a soft heat insulating material 11 is filled inside the panel, and by using the soft heat insulating material, it is possible to reduce the weight and cost of the panel.

In other words, soft insulation materials are generally cheaper and lighter.

In addition, the improved load strength eliminates the need for reinforcing plates, which were always included in conventional floor heating panels.

Furthermore, although floor heating has excellent features such as comfort and safety, its widespread use has been slow due to concerns about the floor load strength and price, but this invention can solve these problems. It is something that
