2. Description of the Related Art Conventionally, floor heating technology for heating from the floor of a house has been proposed and put into practical use for the purpose of improving the livability of a house in a cold region and the livability of a house in a warm region in a cold season. . For example, in single-family homes, a method of incorporating a floor heating radiator plate (also called a panel) on the upper surface (or upper side) of the underlaying plywood laid between the large pulley and the floorboard or on the large pulley is adopted. In multi-family dwellings such as condominiums, a method of laying a floor heating radiator directly on the upper surface of the slab floor or on a sub-plywood laid on the upper surface of the slab floor is adopted. .

A radiating plate (panel) for floor heating is disclosed in, for example, JP-A-60-223922 and JP-A-3-17521.
No. 6, JP-A-4-80596, JP-A-8-2
As described in Japanese Patent No. 61485, a groove or a space is formed on one surface of a plate made of a soft foam or a hard foam, and a flexible tube for a heat medium ( Hereinafter, there is proposed a structure in which a “tube for fluid” is buried, and the surface thereof is covered with a soaking material such as aluminum foil.

In these conventionally known heat radiating plates (panels), a fluid tube is embedded in a narrow and long plate-like body, and in a groove or space formed along the length direction of the plate-like body. It was common to do. When laying a heat sink having such a structure, in many cases, a method of assembling a heat sink in a wide area in advance in a factory and carrying it to a laying site and laying it is adopted. However, according to this conventional method, there is a drawback in that the heat radiation plate assembled in a wide width, when folded, causes the fluid tube to buckle or to be damaged by friction with the groove formed in the plate-like body.

[0005] The buckling of the heat medium tube or the scratching due to friction with the groove formed in the plate-like body is caused by the fact that the fluid tube is placed adjacent to one of the narrow and long plate-like bodies. We focused on the fact that it frequently occurred at the end of the plate that was in communication with the other plate, and as a result of examining ways to resolve these drawbacks, we found that the heat sink had a structure that allowed the end of the plate to be attached and removed. (Japanese Patent Application No. 8-240255). However, as a result of further study, the heat sink with the previously proposed structure could solve the above-mentioned disadvantages, but still had the disadvantage that the number of plate-like bodies was large and the manufacturing and laying operations were complicated. I understand.

[0006]

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
The foldable heat-dissipating member according to the present invention is constituted by a plurality of long and narrow plate-like bodies. After the construction, the heat-dissipating heat-dissipating panel (panel) having a wide width and a long shape is almost square, a wall surface, and a ceiling. Used for forming plates, screens and the like. Further, when a refrigerant is allowed to pass through the fluid tube of the radiator plate instead of the heat medium, it is also used as a cooling radiator plate.

The material of the plate is selected from wood flooring, wood board, plywood, particle board, fiber board, synthetic resin board and the like. Among them, wood materials such as wood flooring, wood board, plywood, and particle board are preferable. In the case of a synthetic resin plate, it is preferable to select from among hard foamed resin flat plates having closed cells and excellent rigidity. Specific examples of the flat plate made of a hard foamed resin include expanded polystyrene, a mixture of expanded polystyrene and expanded polyethylene, expanded polypropylene, hard polyurethane, expanded hard rubber, and the like, but are not limited thereto. The expansion ratio of the synthetic resin plate is
It can be selected in the range of 1.2 to 50 times.

[0012] The thickness of the plate-like body is minimized to the same thickness as the diameter of the fluid tube, and the maximum can be selected within the range of the diameter of the fluid tube plus 25 mm. If the thickness of the plate-like body is more than the diameter of the fluid tube plus 25 mm or more, the member becomes too thick, and the heat transfer from the heat medium tube to the facing material side deteriorates, which is not preferable. The length of the plate is 60-4
You can choose from a range of 00 cm. The width of the plate is 10
You can choose from a range of ~ 100 cm. If the width exceeds 100 cm, the workability of folding, packing, storage, transportation, etc. is inferior.If the width is less than 10 cm, a large number of members are required to obtain a constant width, and the work when folding is complicated. However, it is not preferable because a U-shaped groove for changing the direction of the fluid tube cannot be formed. It is preferable that the plurality of plate-like bodies have the same dimensions in thickness, length, and width.

[0013] On one surface of the heat dissipating member constituted by a plurality of plate-like bodies, an embedding groove of a fluid tube is engraved. The surface on which the buried groove is carved may be either the front side or the back side. The buried grooves are formed as straight grooves, U-shaped grooves and L-shaped grooves. The straight groove is a groove engraved on one surface of the plate-like body along the length direction, and the U-shaped groove is provided at one or both ends in the length direction of the plate-like body, and has a planar shape. A groove for turning a fluid tube by drawing a U-shape or a modified U-shape.

The L-shaped groove is provided at one or both ends in the longitudinal direction of the plate-like body, one of which is connected to the linear groove, and the other is opened at the end wall surface (side wall surface) in the width direction of the plate-like body. Draw a L-shaped or deformed L-shape,
A groove for bridging the fluid tube from one plate-shaped body (A) to another adjacent plate-shaped body (B). The opening in the width direction end wall surface of one plate-shaped body (A) is provided so as to face the opening in the width direction end wall surface of another adjacent plate-shaped body (B). When the L-shaped groove is bent at a right angle, the fluid tube buckles. Therefore, it is preferable to set the bending angle to 90 degrees or more, or to bend the bent portion by forming an arc.

[0015] A deep groove is formed in the opening on the end wall surface in the width direction of one plate-shaped body (A) and / or the other plate-shaped body (B) so as to be connected to this opening. As will be described later, when the foldable heat radiation member according to the present invention is placed on a flat surface, the deep groove is exposed (excess) to a gap provided between adjacent plate-like bodies. It has a function of storing and concealing the tube for installation (see below, FIG. 5). A tongue groove and a tongue and groove are provided on the remaining part of the width direction end wall surface (side wall surface) of the plate-like body, and the structure is such that the two are fitted together during construction. It can also be done.

The foldable heat radiating member according to the present invention comprises:
A gap is provided between the plate-like bodies adjacent to each other, and the structure is connected by a fluid tube (see FIG. 1 described later). The gap between the plate-like bodies functions to make the fluid tube into a semicircular arc so as not to buckle when the foldable heat radiation member is folded. If the gap is too large, the excess fluid tube becomes too long, so it is preferable to select the gap with a minimum width that allows the fluid tube to be formed into a semicircular arc without buckling.

The fluid tubes arranged and embedded in the grooves (straight grooves, U-shaped grooves and L-shaped grooves) have a function of passing a heat medium and a refrigerant through the inner space thereof, and are flexible. It must also be excellent in mechanical strength, heat resistance, chemical resistance, etc. Examples of tubes exhibiting such characteristics include cross-linked polyethylene tubes, polybutene tubes, polypropylene tubes, soft polyvinyl chloride tubes, nylon tubes, and the above-mentioned resin tubes in which a metal wire is embedded in the wall surface of the tube. These are cross-linked polyethylene tubes and polybutene tubes. The outer diameter of the heat medium tube varies depending on the region where the building is constructed, the type of the building, and the like, but can be selected in the range of 3 to 20 mm and the wall thickness in the range of 0.5 to 5 mm.

After the fluid tube is buried in the groove, a thin plate is attached to the buried surface so that the fluid tube does not come off from the buried groove. When the groove is engraved on the surface side of the plate-like body, the thin plate material to be stuck on the surface is a surface covering material. In addition to functioning so that the fluid tube does not fall out of the buried groove, the surface material adds rigidity to the surface of the foldable heat dissipation member, protecting the plate-like body from being crushed or deformed, It fulfills the function of improving the surface appearance of the plate.
In addition, it is preferable to attach a metal foil soaking material such as an aluminum foil between the surface of the plate and the surface covering material, and the heat equalizing material is formed by a groove formed in the surface of the plate. It is preferable to press down to the inner wall surface and stick it. When the thickness of the heat equalizing material is too small, the strength is insufficient and the material tends to be damaged. On the other hand, when the thickness is too large, the cost becomes high. A particularly preferred thickness of the soaking material is in the range of 10 to 200 μm.

Examples of the covering material include plywood, wood board, fiber board, resin board, and particle board, but are not limited to those exemplified. Depending on the type of material of the plate-shaped material, the surface covering material is selected. The surface material may be composed of one sheet or a combination of a plurality of thin small pieces. A paint may be applied to the surface of the facing material, or a grain pattern or another pattern may be printed. If the thickness of the surface material is too small, the above function cannot be exerted. If the thickness is too large, the efficiency of heat transfer from the fluid tube is reduced, and neither is preferable. The thickness of the facing material can be selected in the range of 1 to 10 mm.

When the groove is formed on the back surface of the plate-like body, the thin sheet material to be stuck on the back surface is a backing material. The backing material not only functions to prevent the fluid tube from coming off the buried groove, but also reflects heat to the surface side of the plate-like body, functions as a sound deadening layer, an impact buffer layer, and the like. Examples of the backing material include a nonwoven fabric, a rubber plate, a fiber plate, a resin plate, and a particle board. It is preferable to attach a metal foil soaking material such as an aluminum foil between the back surface of the plate and the backing material. Also in this case, it is preferable to attach a facing material to one surface of the plate-like body.

The foldable heat radiation member according to the present invention comprises:
A plurality of plate-like bodies are arranged with a gap therebetween, connected by a continuous fluid tube, and manufactured in advance at a factory. Since the fluid tube is exposed in the gap between the plurality of plate-like bodies, so as not to buckle this exposed portion, and
It can be folded so as not to damage the surface of the plate, and handling such as storage and transportation to the construction site is easy. When folding the heat-dissipating member according to the present invention, one plate-shaped body (A)
The surface of the plate-shaped body (B) adjacent to the surface of the plate-shaped body (B) is overlapped, the back surface of the plate-shaped body (C) adjacent to the back of the plate-shaped body (C) is overlapped,
The surface of the plate (D) adjacent to the surface of the plate (C) may be overlapped, and the same operation may be repeated thereafter.

Examples of the medium that can be passed through the fluid tube include water, ethylene glycol, propylene glycol, and gas as both the heat medium and the refrigerant. It is preferable that the temperature control device for the heat medium and the refrigerant be installed under the floor, outdoors, on a roof, or the like.

Hereinafter, a method of constructing a heating floor using the foldable heat radiating member according to the present invention will be described. Foldable heat-dissipating members manufactured at the factory in advance

Underground refers to the slab surface in the case of concrete buildings such as condominiums, commercial buildings, hotels, etc., and the underlying floor plywood formed on these, and in the case of detached houses, the underlying floor plywood . It is preferable to lay a nonwoven fabric or a rubber sheet on the lower ground or the base floor plywood. The predetermined position may be the entire floor of the room or a specific position on a part of the floor of the room.

When the construction is performed according to the construction method according to the present invention, first, the plate-like body (A) at the end in the width direction of the foldable heat radiating member (panel) is arranged at the end of the installation place and bonded. Fix it to the ground surface with an adhesive, double-sided adhesive tape, or nails. Next, the tongue groove and the tongue and groove provided on the width direction end wall surface of the adjacent plate-like body (B) are combined with the plate-like body (B).
And the fluid tube exposed in the gap between the plate-shaped body (A) and the plate-shaped body (B) is buried in a groove deeper than the tongue groove and tensioned. Fix it to the ground surface with an adhesive or nail.
