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 buckling of a fluid pipe.

  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.

Several techniques have been disclosed so far for making the heat sink foldable without buckling the fluid piping. For example, in Patent Document 1, a plurality of narrow and long plate-like bodies engraved with an embedded groove for a fluid tube are combined into a square shape, and the fluid tube is embedded in the embedded groove. In a heatsink that can be folded with a plurality of contact parts where the heat dissipation sheet is attached to the whole and the backside material is attached to all or part of the backside, and the ends of adjacent plate-like bodies contact each other. The fluid tube outlet opening at one plate end and the fluid tube inlet opening at the other plate end are provided so as not to oppose each other, and this portion is used as a fluid tube crossover portion to expand and contract. Disclosed is a technique that enables a heat sink to be bent by disposing a crossover member having a property. Patent Document 2 discloses a technique that enables a heat sink to be bent in a form in which a crossover member having elasticity is not provided at a fluid tube transition portion shown in Patent Document 1. Furthermore, in Patent Document 3, a folding floor heating panel that can be folded by folding a panel plate by 180 ° along the joint, and connecting a plurality of panel plates, is oblique to the surface of the panel plate. The hot water tube housing groove is formed on the panel plate, the housing groove is linearly continuous with the housing groove of the adjacent panel plate, and the hot water tube housing groove of the panel plate is adjacent to each panel plate. At the boundary with the panel plate, a tube reversal containing main groove branched from the straight hot water tube receiving groove via the circular portion is formed, and in the adjacent panel plate, with respect to the tube reversing containing main groove A technique is disclosed in which the floor heating panel can be folded by forming the tube reversal accommodation sub-groove in the opposite direction.

  However, in the conventional techniques disclosed in Patent Documents 1 to 3, when the heat sink is folded (hereinafter referred to as “valley fold”) in which the upper surface and the upper surface are aligned in the horizontal direction (or vertical direction). After that, it was not possible to further fold in the vertical direction (or horizontal direction). Therefore, when the heat sink is valley-folded in the horizontal direction (or vertical direction), it is necessary to perform folding (hereinafter referred to as “mountain folding”) in which the lower surface and the lower surface are combined in the vertical direction (or horizontal direction). . As a result, in the conventional foldable heat sink as disclosed in Patent Documents 1 to 3, the folded heat sink can be folded compactly without buckling the fluid piping. There was a problem when deploying at the laying site. Specifically, since the heat sink that has been folded in a mountain is folded in such a manner that the surface on the upper side becomes the surface when laying, there is a problem that it is difficult to deploy it alone at the laying site. . Moreover, when mountain-folding at the connection part of adjacent bases, although the lower surfaces of the adjacent bases are normally connected with the tape which has adhesiveness, the problem that this tape is easy to peel off and bases separate. Has occurred.

  Therefore, an object of the present invention is to provide a foldable heat sink that can be easily packed, transported, and laid, and that can prevent buckling of a fluid pipe.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The present invention is a foldable structure in which a plurality of bases (3) each having a plurality of plate-like bodies (2) with grooves (1) carved on one side are connected via a foldable connecting part (4). And at least one pipe communication part (6a) and the pipe among the pipe communication parts (6) in which the fluid pipe (5) is embedded in the groove and the fluid pipe intersects the connection part. In the boundary line (8) on the extension line of the communication part, an expansion / contraction means (7a) capable of separating adjacent bases is provided, and an expansion / contraction tracking means (7b) is provided in the vicinity of the pipe communication part provided with the expansion / contraction means. The problem is solved by providing a foldable heat sink (10) characterized in that it is provided.

The shape of the groove provided varies depending on the place where the plate-like body is disposed. Further, the “base having a plurality of plate-like bodies” is a member formed by connecting at least a plurality of the plate-like bodies, and not only the plate-like bodies but also plate-like bodies and other plate-like bodies. It may be connected in a form in which small joists or small joists are arranged between the two.
The “connecting portion” means a boundary line between bases connected by some connecting means among the boundary lines between adjacent bases when the heat sink is laid. As a connecting means, for example, a method of connecting the upper surfaces of adjacent bases by pasting a continuous metal soaking plate, or a method of connecting the lower surfaces of adjacent bases by sticking an adhesive tape And so on. Further, the “bendable connecting portion” means, for example, a connecting portion that allows a valley fold by connecting the upper surface of an adjacent substrate and not connecting the lower surface by the connecting means, or the lower surface of an adjacent substrate. Means a connecting part that enables mountain folding by not connecting the top surfaces.
The phrase “fluid pipe intersects with the connecting portion” means that the fluid pipe is buried across the connecting portion. That is, the “pipe communication portion” means a portion of the boundary line between adjacent bases where the fluid pipe straddles.
"At least one or more pipe communication parts and a boundary line on an extension line of the pipe communication parts are provided with expansion / contraction means capable of separating adjacent bases" means that at least one of the plurality of existing pipe communication parts It means that a single pipe communication part and a means capable of bringing adjacent bases into contact with each other via a boundary line on an extension line of the pipe communication part and pulling them apart are provided. As a specific configuration example of the “extension / contraction means”, for example, a configuration composed of a plurality of bases that are not connected to each other on the upper surface and the lower surface but are connected only by a fluid pipe. By adopting such a configuration, the adjacent substrates can be brought into contact with each other or can be separated without being completely separated (the distance between adjacent substrates can be increased), so that the distance between adjacent substrates can be expanded and contracted. be able to. Furthermore, “an expansion / contraction follower is provided in the vicinity of the pipe communication portion provided with the expansion / contraction means” means that the distance between adjacent bases via the pipe communication portion is extended or reduced in the vicinity of the pipe communication portion provided with the expansion / contraction means. On the other hand, it means that the fluid piping is provided with means that can follow. As a specific configuration example of the “extension / contraction follower”, for example, a configuration including a groove cut larger than a pipe diameter of the fluid pipe and a fluid pipe that can move flexibly in the groove is given. be able to. By adopting such a configuration, when the bases connected by the fluid pipes are in contact with each other, the fluid pipes are embedded in a direction nearly parallel to the boundary line between the bases, and the bases are connected. When separating them from each other, the fluid piping can flexibly move in a direction perpendicular to the boundary line, so that the fluid piping can follow the expansion and contraction of the distance between the substrates.

  According to the foldable heat sink according to the present invention, when the expansion / contraction means capable of separating the bases on the horizontal boundary line is provided, the valley can be further folded in the vertical direction after being folded in the horizontal direction. Is possible. When the expansion / contraction means is provided on the boundary line in the vertical direction, it is possible to further fold in the horizontal direction after the vertical fold. That is, according to the present invention, it is possible to provide a foldable heat sink that can be folded only by valley folding and can be folded into a state where it can be easily deployed at the laying site. Further, according to the folding heat sink of the present invention, the piping communication portion is provided with a buckling prevention means, and the pipe communication portion provided with the expansion / contraction means is provided with expansion / contraction follow-up means. The fluid pipe can be easily folded without applying an extra force. Furthermore, since all the bases are each connected to any other base, the bases are not completely separated. Therefore, according to the present invention, it is possible to provide a foldable heat sink that can be easily packed, transported, and laid and that can prevent buckling of the fluid piping.

  Such an operation and gain of the present invention will be made clear from the best mode for carrying out the invention described below.

  The present invention will be described below based on the embodiments shown in the drawings. However, what is described below is an example of the embodiments of the present invention, and the present invention is not limited to the following descriptions unless it exceeds the gist. is not.

  FIG. 1 is a top view schematically showing a folding heat sink according to the present invention. In FIG. 1, some symbols are omitted in order to prevent the diagram from becoming complicated.

  As shown in FIG. 1, a foldable heat sink 10 (hereinafter simply referred to as “heat sink 10”) according to the present invention has a plurality of plate-like bodies 2, 2,. 2 (see FIG. 2) (hereinafter referred to as “base 3a”, “base 3b”, “base 3c”, and “base 3d”, respectively, when it is necessary to distinguish). , A plurality of connecting portions 4, 4, 4 (hereinafter referred to as “connecting portion 4 a”, “connecting portion 4 b”, and “connecting portion 4 c”, respectively, when it is necessary to distinguish). Has been. Further, a header 70 is provided, and in the groove 1, a fluid pipe 5 is embedded to circulate a fluid that exits the header 70 and returns to the header 70, and the fluid pipe 5 intersects the connecting portions 4, 4, 4. Pipe communication portions 6, 6,. The pipe communication portions 6, 6,... Are provided with means for preventing buckling of the fluid pipe 5. The means for preventing buckling of the fluid pipe 5 in the pipe communication portion 6 is not particularly limited, and examples thereof include a means for embedding the fluid pipe 5 along the pipe communication portion 6 for a certain distance. By doing so, when the bases adjacent to each other are bent through the pipe communication part 6, the fluid pipe 5 embedded along the pipe communication part 6 is twisted in the bending direction of the base to prevent buckling. it can. On the other hand, expansion / contraction means 7a is provided on the pipe communication portion 6a and the boundary line 8 on the extension line of the pipe communication portion 6a, and expansion / contraction follower means 7b is provided in the vicinity of the pipe communication portion 6a. With this configuration, the base 3a and the base 3b, and the base 3c and the base 3d can be brought into contact with or separated from each other. Details of the expansion / contraction means 7a and the expansion / contraction follow-up means 7b will be described later.

  FIG. 2 is a top view schematically showing the base 3a in order to easily show the configuration of the bases 3, 3,... 2, components having the same configuration as in FIG. 1 are denoted by the same reference numerals as those used in FIG. 1, and description thereof will be omitted as appropriate.

  As shown in FIG. 2, the base 3a is composed of a plurality of plate-like bodies 2, 2,..., Small joists 9a, 9a,. The plate-like bodies 2, 2,... Have plate-like bodies 2a, 2a,... Having the curved portion of the groove 1 and plate-like bodies 2b, 2b,. . The plate-like bodies 2a, 2a,... And the plate-like bodies 2b, 2b,... Can be manufactured with an integral mold or the like, but the plate-like bodies 2a, 2a,. ,... Are manufactured using separate molds and the like, and then the base 3a can be easily manufactured by combining them.

  FIG. 3 is a top view in which small joists and grooves are omitted in order to show how the bases 3, 3,... 3, components having the same configuration as in FIG. 1 are denoted by the same reference numerals as those used in FIG. 1, and description thereof will be omitted as appropriate.

  As shown in FIG. 3, the base 3a and the base 3c are connected at a connecting portion 4a, the base 3a and the base 3b are connected at a connecting portion 4b, and the base 3c and the base 3d are connected at a connecting portion 4c. The connection part 4b and the connection part 4c will not be specifically limited if it is a form in which valley folding is possible. In order to enable valley folding in the connecting part 4b and the connecting part 4c, for example, in the connecting part 4b, the upper surfaces of the base 3a and the base 3b are connected by a continuous metal (eg, aluminum foil) soaking plate. By not connecting the lower surface, the base 3a and the base 3b can be valley-folded in the connecting portion 4b. Also in the connecting portion 4c, the base 3c and the base 3d can be folded at the connecting portion 4c by connecting the base 3c and the base 3d by the same means as the connecting portion 4b.

(Extension / contraction means 7a)
On the other hand, the connecting part 4a is provided with a pipe communication part 6a, and the boundary line 8 on the extension line of the pipe communication part 6a and the pipe communication part 6a is provided with the expansion / contraction means 7a as described above. Yes. FIG. 4 is a diagram schematically showing the expansion / contraction means 7a. FIG. 4A shows a state in which the base 3a and the base 3b, and the base 3c and the base 3d are in contact with each other (hereinafter sometimes referred to as a “contracted state”), and FIG. , The base 3a and the base 3b, and the base 3c and the base 3d are separated (hereinafter, referred to as “extended state”).

  Specifically, the expansion / contraction means 7a is discontinuous with a soaking plate or the like attached to the upper surface at the boundary line 8, and the lower surface is not connected, and the connecting portion 4a is adjacent only by the fluid pipe 5. The bases 3a, 3b, 3c, and 3d are connected to each other. By providing such expansion and contraction means 7a, as shown in FIG. 4 (a), in the contracted state, the difference in appearance from the conventional folding heat sink is difficult to understand, but as shown in FIG. 4 (b), It becomes possible to separate the bases that are adjacent via the boundary line 8 into an extended state. That is, the expansion / contraction means 7a can expand and contract the distance between the base 3a and the base 3b, and the base 3c and the base 3d. In the extended state, since the base 3a and the base 3c are connected by the fluid pipe 5, the base 3a, the base 3b, and the base 3c and the base 3d are not completely separated.

(Extension / contraction follower 7b)
FIG. 5 is a diagram schematically showing the expansion / contraction follower 7b. FIG. 5A shows a contracted state (a state where the base 3a and the base 3c are in contact), and FIG. 5B shows an extended state (a state where the base 3a and the base 3c are separated). Show.

  As described above, in the folding heat sink 10, the distance between the base 3a and the base 3b, and the base 3c and the base 3d can be extended and contracted by the expansion / contraction means 7a. At this time, the expansion / contraction follower 7b is required to expand / contract the pipe 5 for fluid without applying extra force in the pipe communication portion 6a.

  Specifically, the expansion / contraction follower 7b includes a groove 1a engraved larger than the pipe diameter of the fluid pipe 5 in the vicinity of the pipe communication portion 6a, a parallel groove 1b engraved along the pipe communication portion 6a, and a flexible The fluid pipe 5 is configured. By this expansion / contraction follow-up means 7b, the fluid pipe 5 can follow the expansion / contraction of the expansion / contraction means 7a. Specifically, in the contracted state, as shown in FIG. 5A, the fluid pipe 5 is embedded substantially parallel to the pipe communication portion 6 a, and the fluid pipe 5 is placed in the groove 1. Moreover, as the fluid pipe 5 is kept in the groove 1 on the base 3a and the base 3c, the fluid pipe 5 is perpendicular to the pipe communication portion 6a as it goes from the contracted state to the extended state. It moves flexibly in the near direction, and in the extended state, the state is as shown in FIG.

  However, in the present invention, the expansion / contraction follow-up means is not limited to the above form. The expansion / contraction follow-up means according to the present invention allows the bases adjacent to each other to be separated from each other through the pipe communication portion without applying excessive force, and when the bases are in contact with each other, the fluid pipes remain. Any form that fits in the groove without any problem is acceptable. For example, as shown in FIG. 7, a configuration in which the planar shape includes a substantially right-angled triangular groove 11 and a flexible fluid pipe 5 that obliquely crosses the pipe communication portion may be employed. FIG. 7A shows a state where the base 13a and the base 13c are in contact, and FIG. 7B shows a state where the base 13a and the base 13c are separated. As shown in FIG. 7, when the base plate 13a and the base plate 13c are in contact with each other, the groove 11 in the vicinity of the pipe communication portion is engraved so that the planar shape is a substantially right triangle. However, it is possible to keep the fluid pipe 5 in the groove 11 on the base 13a and the base 13c. However, in order to increase the distance when the adjacent bases are separated through the pipe communication part, a form having parallel grooves cut along the pipe communication part is preferable.

  FIG. 6 is a view schematically showing a cross section in a direction perpendicular to the longitudinal direction of the fluid pipe 5 at a portion indicated by VI-VI ′ in FIG. 5. As shown in FIG. 6, the parallel groove 1 b is in a form that is engraved across the base 3 a and the base 3 c. By adopting such a configuration, when the base 3a and the base 3c are separated, the distance between the base 3a and the base 3c can be easily earned.

  However, in the present invention, the form of the parallel grooves is not limited to the above form. For example, a form as shown in FIG. 8 is also conceivable. FIG. 8 shows a direction perpendicular to the longitudinal direction of the fluid pipe 5 in the form in which the fluid pipe 5 is embedded in the groove 21 formed along the pipe communication portion of the adjacent base 23a and the base 23c. It is the figure which showed the cross section roughly. That is, in the present invention, as shown in FIG. 8, it is also possible to form a parallel groove by engraving the groove 21 only on one base 23c among the adjacent bases.

  As described above, in the heat radiating plate 10, the expansion / contraction means 7a and the expansion / contraction follow-up means 7b are provided, so that an extra force is not applied to the fluid pipe 5, and the base 3a, the base 3b, and The base 3c and the base 3d can be separated from each other by a certain distance. Therefore, when the heat sink 10 is folded, first, the heat sink 10 is valley-folded at the connecting portions 4b and 4c, and then the base 3a, the base 3b, the base 3c, and the base 3d by the expansion / contraction means 7a and the expansion / contraction follower 7b. Can be separated from each other by a certain distance, and the base 3a and the base 3b, and the base 3c and the base 3d can be folded at the connecting portion 4a. By doing so, it is folded in a state where the surface on the lower surface becomes the surface when laying, so that it can be easily deployed at the laying site.

  In the description so far, the form in which small joists and small joists are provided has been described. However, the presence or absence of small joists and small joists does not affect the effect obtained by the present invention. The effect of the present invention can be obtained even if the joist is not provided.

  Furthermore, although the description so far has described a form in which only one expansion / contraction means and one expansion / contraction follower are provided, the present invention is not limited to such a form. Another embodiment of the folding heat sink according to the present invention will be described below with reference to FIGS. 9 and 10.

In the heat dissipation plate 80, the base 83a and the base 83b are connected at the connecting portion 84b, the base 83b and the base 83c are connected at the connecting portion 84c, the base 83a and the base 83d are connected at the connecting portion 84a, and the connecting portion 84d. The base 83d is connected to the base 83e, and the base 83e and the base 83f are connected to each other at the connecting portion 84e. The boundary line 88a on the extension line of the connecting portion 84a and the boundary line 88b on the extension line of the connecting portion 84b (84d) are respectively provided with expansion / contraction means, and are provided on the boundary line 88a and the boundary line 88b. In the vicinity of the pipe communication portion, expansion / contraction follow-up means is provided. By setting it as this form, the distance of the board | substrates which adjoin through the boundary line 88a and the boundary line 88b can be expanded-contracted. That is, when folding the heat sink 80, it is possible to fold each other at the connecting portion 84c and the connecting portion 84e, and then to further fold at the connecting portion 84b and the connecting portion 84d, and further to the connecting wire 84a. In this case, the heat sink 80 can be folded only by valley folding. Therefore, the heat sink 80 can be folded into a form that can be easily deployed at the site of installation.

The heat radiating plate 90 is provided with a header near the center of the heat radiating plate 90, the base 93a and the base 93b are connected at the connecting portion 94b, the base 93b and the base 93c are connected at the connecting portion 94c, and the connecting portion 94a. The base 93b and the base 93e are connected to each other, the base 93d and the base 93e are connected to each other at the connecting portion 94d, and the base 93e and the base 93f are connected to each other at the connecting portion 94e. The boundary line 98a on the extension line of the connecting portion 94a and the boundary line 98b on the extension line of the connecting portion 94b (94d) are respectively provided with expansion / contraction means, and are provided on the boundary line 98a and the boundary line 98b. In the vicinity of the pipe communication portion, expansion / contraction follow-up means is provided. By setting it as this form, the distance of the board | substrates which adjoin through the boundary line 98a and the boundary line 98b can be expanded-contracted. That is, when the heat sink 90 is folded, it can be folded at the connecting portion 94c and the connecting portion 94e, and then can be further folded at the connecting portion 94b and the connecting portion 94d, and the connecting wire 94a. The heat sink 90 can be folded only by valley folding. Therefore, the heat sink 90 can be folded into a form that can be easily deployed at the site of installation.
