Description

  The present disclosure relates to a heat dissipation sheet disposed in an underfloor space of a building.

  In buildings, it is conceivable to provide a heat dissipation sheet in the underfloor space and to heat the floor or the room by radiant heat, conductive heat through members constituting the floor, or heat of warmed underfloor space air. Since the heat-radiating sheet mainly uses radiant heat, it is desirable that the heat-radiating sheet be efficiently disposed over the entire floor. However, if the heat-radiating sheet has a size that covers the entire floor, handling during transportation or installation becomes difficult.

  Therefore, it is considered that the heat dissipating sheet is configured to be foldable (see Patent Document 1). In the heat dissipating sheet, two long mat plates provided with a hot water pipe are foldable in the longitudinal direction or at a central portion in the longitudinal direction, and the hot water pipes of the mat plates are connected to each other. The heat-radiating sheet can be transported to the installation position in a folded state, so that handling during transportation or installation can be facilitated.

Furthermore, in order to make it easy to grasp each configuration, FIG. FIG. 6 shows how the heat dissipation sheet 10 is changed from the folded state Sf to the arranged state Sp in four stages and arranged in the vertical direction, and in order to avoid complication, each configuration is simplified and shown.

  The heat-radiating sheet 10 of Example 1 which concerns on one Embodiment of the heat-radiating sheet which concerns on this indication is demonstrated using FIGS. 1-6. The heat-radiating sheet 10 is used to warm the room and the floor by using the space under the floor of the building, and in the first embodiment, the floor heating system used for a building such as a unit building is configured.

  The floor heating system is configured by connecting a heat pump as a heat source to a plurality of heat dissipation sheets 10 provided in the first floor lower floor space, the second floor lower floor space (space between upper and lower floors), and the like. In the floor heating system, the heat medium which the heat pump absorbs the heat energy in the air is circulated with each heat dissipation sheet 10 to radiate heat toward the periphery of the place where each heat dissipation sheet 10 is installed, and provided Warm the floor and the like above the floor space below. Each heat-radiating sheet 10 can be efficiently used for the released heat by being disposed in the underfloor space with a heat insulating material interposed. The floor heating system has a controller for setting a desired operation such as temperature setting, and the controller is appropriately provided in a living room space or the like above the underfloor space provided with each heat radiation sheet 10.

  As shown in FIGS. 1 and 2, the heat dissipation sheet 10 is configured by connecting a plurality of strip portions 11. The strip-like parts 11 are generally in the form of a long rectangular plate in a front view, and are provided side by side in the short direction Ds (width direction). The strip-like portion 11 is formed of a plate material capable of fixing the heating pipe 12 on the surface 11 a, and is preferably formed of a lightweight heat insulating material. In the first embodiment, the strip-shaped portions 11 are formed of plastic cardboard, and seven pieces are arranged in the short direction Ds (hereinafter, also referred to as an arrangement state Sp). In the following, when describing each strip-shaped part 11 individually, 1 to 7 will be added to the end of the code | symbol sequentially from a left view of FIG.

  The heating pipe 12 is a pipe through which the heat medium supplied from the heat pump passes, and is provided around the surface 11 a so as to extend over the entire surface 11 a of each strip 11. In the first embodiment, each heating pipe 12 is formed of cross-linked polyethylene so that it reciprocates twice in the longitudinal direction Dl between one end side and the other end side in the longitudinal direction Dl of the corresponding strip-shaped portion 11 It is folded back in a U-shape. For this reason, in each heating pipe 12, both end edges 12 a serving as the inlet and outlet of the heat medium are positioned on one end side in one of the lengthwise direction Dl of the strip-like portion 11. In the arrangement state Sp, each strip-shaped portion 11 is positioned such that the inlet / outlet (both ends 12a) of the heating pipe 12 is opposite to the adjacent strip-shaped portion 11 in the longitudinal direction D1, that is, the inlet / outlet is one end The direction is set to be alternately located on the other end side.

  The heat dissipation member 13 is provided at least on the surface 11 a of each strip 11 (see FIG. 3). Each heat radiating member 13 efficiently radiates the heat of the heating pipe 12 and is provided to cover the entire surface 11 a from above the heating pipe 12. The heat radiating member 13 is a black thin film member made of an aluminum material in the first embodiment.

  As shown in FIG. 2, the strip-shaped parts 11 are integrated by connecting adjacent ones in the arrangement state Sp by the connecting member 14. The connecting member 14 connects the long sides of the adjacent two strip-like parts 11, and in the first embodiment, the connecting member 14 is a tape, and both long side parts extend substantially the entire length of the long sides of the two strip-like parts 11. They are linked to each other by bridging. Each connecting member 14 has an arrangement state Sp (see FIG. 1) in which the strip-like portions 11 are arranged, and a state in which the strip-like portions 11 are folded as will be described later (hereinafter referred to as a folded state Sf (see FIG. 5) The adjacent strip-like parts 11 are connected so as to enable the transition between) and. That is, each connecting member 14 connects the both long side portions while allowing the positional relationship between the long side portions of adjacent two strip-like portions 11 and the interval to be changed between the arrangement state Sp and the folded state Sf. ing. In the first embodiment, each connecting member 14 connects the adjacent two strip-like parts 11 outside each other when the two adjacent strip-like parts 11 are folded (see FIG. 5). From these things, each connection member 14 functions as six connection locations C of the respective strip-like parts 11 arranged in the short direction Ds. In the following, when describing each connection part C individually, 1 to 6 are added to the end of the reference in order from the left side when viewing FIG. 1 from the front.

  As shown in FIG. 1 and FIG. 2, the heating pipes 12 of each strip-shaped portion 11 are connected by connection pipes 15. Each of the connection pipes 15 is for connecting the heating pipes 12 of the two adjacent strip-shaped parts 11 in the arrangement state Sp. In the first embodiment, each connection point C is formed between the seven strip-shaped parts 11. It is provided in six places to straddle. Each of the connection pipes 15 cooperates with the connected heating pipes 12 to form a single (one-stroke) path of a heat medium. In the following, when describing each of the connection pipes 15 individually, FIG. 1 is viewed from the front, and from the left side, 1 to 6 are added to the end of the reference numerals. Each connecting pipe 15 is formed of a flexible material, and has a dimension longer than the distance d between the edges 12a (outlet) of the heating pipes 12 connected in the arrangement state Sp. It has the same diameter as. In the first embodiment, each connection pipe 15 is formed of cross-linked polyethylene, and has a length dimension that meanders largely between the edges 12 a of the heating pipes 12 connected in the arrangement state Sp. Thereby, each connecting piping 15 has flexibility and a dimension longer than the interval d, even if each strip-like portion 11 is shifted between the arrangement state Sp and the folded state Sf to be described later. It is possible to absorb the twist generated at both ends by the transition, and to connect the heat medium without collapsing between the corresponding edges 12 a of the heating pipes 12. In the first embodiment, the outer diameter of the end 12 a of each heating pipe 12 is partially reduced, and it is possible to insert the corresponding connection pipe 15 so as to cover it. In addition, the piping 12 for heating and the piping 15 for connection should just be a structure which can mutually be connected, and are not limited to the structure of Example 1. FIG.

  As shown in FIGS. 4 and 5, in each of the strip-like parts 11, six connected portions C aligned in the short direction Ds are alternately arranged in the short direction Ds as viewed from the surface 11a side. As folded. Here, the mountain fold means that the two strip-like parts 11 are superimposed so that the back surfaces 11b of the two adjacent strip-like parts 11 face each other (refer to the connecting portion C2 in FIG. 4). It means that the two strip-shaped parts 11 are piled up so that the surfaces 11a of two matching strip-shaped parts 11 may face (refer the connection location C1 of FIG. 4). In each of the strip-like parts 11, in the first embodiment, the connection points C1, C3 and C5 are valley-folded, and the connection points C2, C4 and C6 are mountain-folded and folded, as shown in FIG. The state Sf is set.

  In each of the connection pipes 15, the one straddling the valley-fold connected portion C is located on the back surface 11 b side of each strip-like portion 11 and the one straddling the mountain-fold connected portion C on the surface 11 a side of each strip-shaped portion 11. It is supposed to be. Each connecting pipe 15 corresponding to the valley fold is connected to the heating pipe 12 (the end thereof) provided on the surface 11 a of the strip-like portion 11, and then the connecting member 14 of the connecting portion C straddled by itself. It extends from between the two strip-like parts 11 to the back surface 11 b side of each of the strip-like parts 11 through the holes provided in (see FIGS. 3 and 4). For this reason, connection pipes 151, 153, 155 are disposed on the back surface 11b side of each strip 11 and connection pipes 152, 154, 156 are disposed on the surface 11a of each strip 11 (FIG. 1). , See Figure 2). As a result, each connecting pipe 15 is projected to the outside of each strip 11 from both sides in the short direction Ds when each strip 11 is in the folded state Sf (see FIG. 5).

  Next, a mode of use of the heat dissipation sheet 10 will be described. First, as shown in FIG. 5, the heat-radiating sheet 10 is in a folded state Sf in which the strip-like portions 11 are folded in a so-called folding screen shape in which mountain folds and valley folds are alternately arranged during storage or transportation. It is assumed. Here, in the heat dissipating sheet 10, when in the folded state Sf, the connection pipes 15 are protruded to both sides of the strip-shaped portions 11 and do not enter between the strip-shaped portions 11.

  At the time of installation, the heat dissipation sheet 10 is arranged in the folded state Sf at one end in the installation area to be installed. At this time, as shown in the upper part of FIG. 6, the heat dissipation sheet 10 is a connecting member of the lower strip 11 while the back surface 11b of the lower strip 11 is directed downward in the vertical direction. The long side not provided with 14 is installed toward one end. Then, in the heat dissipation sheet 10, when the even numbered strip-shaped portions 11 are connected, the back surface 11b of the uppermost strip-shaped portion 11 faces upward in the vertical direction, and the odd numbered strip-shaped portions 11 are connected. In this case, the surface 11 a of the uppermost strip 11 faces vertically upward.

  Then, as shown in the second and third stages of FIG. 6, the heat-radiating sheet 10 has the surface 11a of the uppermost strip 11 upward in the vertical direction regardless of whether it is an even number or an odd number as shown in the second and third stages of FIG. When the long side on which the connecting member 14 is not provided is pulled toward the other end of the installation area while being directed, the connected strip-like parts 11 are sequentially drawn out with the surface 11 a facing upward in the vertical direction Go. Then, as shown in the lower part of FIG. 6, when the heat dissipation sheet 10 is pulled up to the other end in the installation area, all the strip shapes are directed with the surface 11a facing upward as shown in the lower part of FIG. An arrangement state Sp in which the portions 11 are aligned in the short direction Ds is obtained. In the arrangement state Sp, the heat dissipation sheet 10 can form a large panel-shaped heat dissipation sheet by the seven strip-like portions 11 arranged in a predetermined positional relationship.

  Thus, the heat dissipation sheet 10 can be easily placed in the disposition state Sp. Since the heat-radiating sheet 10 has the connection pipes 15 protruding on both sides of the strip portions 11, it is possible to prevent the strip portions 11 from being prevented from being pulled out or being entangled in the spreading operation. In addition, since each strip-shaped portion 11 is connected by each connecting member 14, the heat-dissipating sheet 10 is pulled without performing troublesome work such as adjustment of the positional relationship such as the spacing and alignment order of each strip-shaped portion 11. The positional relationship of each strip-shaped part 11 can be made what was set only.

  The heat dissipation sheet 10 according to an embodiment of the heat dissipation sheet according to the present disclosure can obtain the following effects.

  The heat dissipation sheet 10 is connected by the connecting member 14 in a state where the plurality of strip-shaped portions 11 provided with the heating pipes 12 are arranged side by side in a predetermined positional relationship, and both heating of two adjacent strip-shaped portions 11 are performed. The connecting pipe 12 is connected by a connecting pipe 15. And the heat dissipation sheet 10 makes it possible to fold so that the two strip-like parts 11 which the connection member 14 adjoins may overlap, and the end of both the heating pipings 12 which the piping 15 for connection connects, having flexibility. The dimension is longer than the distance d of the edge 12a. For this reason, the heat dissipation sheet 10 can enable transition between the state (arrangement state Sp) and the folded state (arrangement state Sp) in which the respective strip-like portions 11 are arranged, and the respective strip-shaped portions 11 in the arrangement state Sp The positional relationship can be set. Here, when the hot water pipes (corresponding to the heating pipe 12 and the connecting pipe 15) of two mat plates (corresponding to the strip-like portion 11) are connected to each other as in the prior art, they are arranged There is nothing to define the positional relationship between the two mat plates, and it is not easy to arrange them in a predetermined positional relationship. On the other hand, since the heat dissipation sheet 10 defines the positional relationship between the two strip-like parts 11 adjacent to each other, the positional relationship of each connecting member 14 can be made predetermined only by setting it to the disposition state Sp. Can be arranged efficiently across the floor.

  In the heat-dissipating sheet 10, each strip-shaped portion 11 is in the form of a long plate, and the connecting member 14 arranges the strip-shaped portions 11 in the short direction Ds and forms mountain folds and valley folds in the short direction Ds. The strip-like parts 11 are connected so as to be folded in a so-called folding screen alternately arranged. For this reason, the heat dissipation sheet 10 can fold the plurality of strip-like parts 11 efficiently into a folded state Sf, and can be easily carried and stored. In addition, when the heat dissipation sheet 10 is pulled from the folded state Sf to the long side where the connecting member 14 is not provided while the surface 11a of the uppermost strip-shaped portion 11 is directed upward, the respective strip-shaped portions connected 11 can be drawn out one after another with the surface 11a facing upward in the vertical direction, so that all the strip-like parts 11 can be arranged Sp aligned in the short direction Ds. For this reason, the heat dissipation sheet 10 can be easily arranged in a predetermined positional relationship while spreading the plurality of strip-shaped portions 11 from the folded state Sf to the arranged state Sp.

  Furthermore, in the position where the heat dissipation sheet 10 is mountain-folded, the connection pipes 15 are provided on the surface 11 a side, and in the valley-fold position, the connection pipes 15 are provided on the back surface 11 b side. For this reason, assuming that the heat dissipation sheet 10 is in a folded state Sf in which the respective strip-shaped portions 11 are folded in a so-called folding shape, the connection pipes 15 are outside the respective strip-shaped portions 11 (the short direction Ds of And the increase in the thickness dimension (the direction in which the strip-like parts 11 are overlapped) in the folded state Sf can be suppressed. In addition, since the heat radiating sheet 10 has the connecting pipes 15 located on the outer side of the strip portions 11, the connecting pipes 15 inhibit the operation of the heat radiating sheet 10 when extending from the folded state Sf to the arranged state Sp. Also, the connection piping 15 can be prevented from being entangled.

  Since the heat-radiating sheet 10 is folded in a so-called folding-like state in which mountain folds and valley folds are alternately arranged to form a folded state Sf, even if three or more strip-like portions 11 are used, Regardless, the same configuration can be used, so that efficient folding and spreading operations can be facilitated, and handling can be facilitated as a size covering the entire floor.

  Therefore, in the heat dissipation sheet 10 of the first embodiment as a heat dissipation sheet according to the present disclosure, the entire surface of the floor can be easily disposed efficiently.

  As mentioned above, although the thermal radiation sheet 10 of this indication was demonstrated based on Example 1, it is not restricted about Example 1 about a specific structure, It deviates from the summary of the invention which concerns on each claim of a claim. Unless otherwise noted, design changes or additions are permitted.

  For example, in Example 1, seven strip-shaped parts 11 are connected and comprised. However, the number of strip-shaped parts 11 may be appropriately set including odd number or even number, and is not limited to the configuration of the first embodiment.

  Further, in Example 1, each strip-shaped portion 11 is connected to each connecting member so that each strip-shaped portion 11 can be folded in a so-called folding screen form in which mountain folds and valley folds are alternately arranged in the short direction Ds. It is connected at 14. However, as long as adjacent strip-shaped portions 11 adjacent to each other are connected by the connecting member 14 in a state of arranging in a predetermined positional relationship, the arranging method and the folding method may be appropriately set, and the configuration is not limited to the first embodiment. .

  Furthermore, in the first embodiment, so-called folding-like folding is performed to obtain a folded state Sf, and at the position where mountain folding is performed, each connecting piping 15 is provided on the surface 11a side on which heating piping 12 is provided. In the position where the connecting pipe 15 is provided on the back surface 11 b side. However, the connecting pipes 15 are not limited to the configuration of the first embodiment as long as they connect the heating pipes 12 of the adjacent strip-shaped parts 11 in a state of being arranged side by side in a predetermined positional relationship.

  In the first embodiment, each connecting member 14 connects the adjacent two strip-shaped parts 11 outside each other when the adjacent two strip-shaped parts 11 are folded. However, if each connecting member 14 connects the adjacent two strip-like parts 11 so as to enable the transition between the arrangement state Sp and the folded state Sf, they are connected inside the two strip-like parts 11 It may be connected, it may connect on both sides inside and outside, it may be other composition, and is not limited to composition of Example 1.
