Description

  The present invention relates to a folding heat sink that is preferably used in a floor heating system. More specifically, the present invention relates to a foldable heat sink that can be easily packed, transported, and laid, and that can prevent damage to fluid piping.

  Conventionally, various heating technologies have been proposed and put into practical use for the purpose of improving the comfort of living spaces in structures such as cold seasons in cold regions and houses in cold regions. Most of them are floor heating systems that are placed on the floor of the living space. As an example of the floor heating system, a foamed synthetic resin plate or a wooden plate is used as a base, and a heat medium pipe is embedded in a groove carved on one surface thereof, and these surfaces are made of aluminum. The thing provided with the heat sink of the structure coat | covered with flexible thin plates (soaking plate), such as foil, is mentioned. In this system, the floor surface is warmed by the heat medium flowing through the heat medium pipe disposed in the heat radiating plate of the floor heating system, and the room is heated by the radiant heat from the floor surface.

  The heat radiating plate is spread over a heating place such as a floor surface of a living room, and is usually large. Therefore, the means of carrying the heat sink in a folded state to the laying site and deploying at the laying site is adopted.

In conventional folding heat sinks, the upper surfaces of adjacent substrates are connected by a heat equalizing plate at the location where the upper surfaces of the adjacent substrates are folded in a direction approaching the upper surface (hereinafter referred to as “valley folding”). The bottom surfaces are made discontinuous to enable valley folding. At this time, there is an advantage that the heat equalizing plates attached to the upper surfaces of the adjacent bases are brought into close contact with each other and folded so that the packaging is stable and the heat radiating plate is not damaged during transportation. (Patent Document 1)
JP 2007-93029 A

  However, in the conventional foldable heat sink, when the valley is folded, the top surfaces of the adjacent bases connected to each other are folded so that the valleys are folded in one direction. Further valley folding was not possible in a direction substantially perpendicular to the direction. Therefore, when the heat sink is valley-folded in one direction, it is necessary to perform folding (hereinafter referred to as “mountain folding”) so that the lower surface and the lower surface are brought close to each other in a direction substantially orthogonal to that direction. . As a result, the conventional foldable heat sink has a problem that even if it is possible to fold the heat sink in a compact manner, it is difficult to deploy it alone at the laying site. In addition, since the fluid piping is partially exposed, there is a risk of damage to the fluid piping, and it is troublesome to stretch the heat equalizing plate after the heat sink is deployed.

  Then, this invention makes it a subject to provide the folding-type heat sink which can be easily packed, conveyed, and laid, and can prevent damage to piping for fluid.

In the heat radiating plate 10, the small base 7 is disposed between the first connecting plate 8 a and the second connecting plate 8 b, thereby forming a gap 20 as shown by the hatched portion. When laying the heat sink 10, a member different from the member constituting the heat sink 10 is disposed in the gap 20. This other member is not particularly limited. For example, when a member made of the same material (for example, wood or resin) as Kokonita 9a or Kokonita 9b is used, a nail is used when constructing the flooring from above the radiator plate 10. Easy to install. Further, when not considering hitting a nail, it is preferable to use a heat insulating member (for example, beaded polystyrene foam) because of good thermal efficiency.

When the flooring 51 is constructed, the flow long 51 is fixed by a nail 52, and the nail 52 is struck every other length (303 mm) in the width direction of one flooring. At this time, since the nail 52 penetrates the heat radiating plate 10, if the nail 52 is hit from above the place where the fluid pipe 5 is disposed, the fluid pipe 5 may be damaged and the heat medium flowing through the fluid pipe 5 may leak. There is. Therefore, when constructing the flooring 51 from above the heat radiating plate 10, it is necessary to avoid hitting the nail 52 at the place where the fluid pipe 5 is embedded, and the nail 52 is positioned along the small joist 9a. I will hit it. However, the pipe traverse part 11 exists on the extended line of the small joists 9a, and it is necessary not to hit the nail 52 in the pipe traverse part 11.

Pipe traversing portions 11 are provided on the lower end surface 12a side of the connecting plate 8b and the upper end surface 12b side of the second connecting plate 8b, respectively. As described above, the width t of the first connecting plate 8a is 303 × n ₁ ± 20 mm (n ₁ is a natural number), and the total length s of the width of the small base 7 and the width of the second connecting plate 8b is Since it is 303 × n ₂ ± 20 mm (n ₂ is a natural number), the lower end surface 13b side of the first connecting plate 8a, the upper end surface 13a side of the first connecting plate 8a, and the upper end surface 12b of the second connecting plate 8b.

By folding the valley at the valley fold 6b, it is folded as shown in FIG. Since the heat sink 10 is folded in this way, the length in the B direction of the small base 7 is the base 3a that is sandwiched between the base 3b and the base 3e that are connected to both ends of the small base 7 when folded. It is preferable that the total thickness of the base 3c, the base 3d, and the base 3f is longer.
