Description

  The present invention relates to a heat dissipation panel for cooling and heating, and more particularly, for example, a heat dissipation panel laid as a floor heating base for flooring, wherein hot water is circulated in a heat insulating material formed by arranging a plurality of foamed resin bases. The present invention relates to a heat-dissipating panel for cooling and heating in which a water pipe as a road is embedded and can be folded into a mountain fold and a valley fold in units of a base.

  For example, in the construction of floor heating, as a foundation for floor finishing materials such as flooring, a water pipe as a hot water circulation path is embedded on the front side of a heat insulating material made of a thin plate-like foamed resin molded body, and a heat radiating sheet for heat diffusion is used. A heat dissipating panel is used which is made by adhering, circulating hot water supplied from a boiler to a water pipe, and supplying heat of the hot water to the room side. In such a heat dissipation panel, the heat insulating material is constituted by a plurality of bases, and is folded into mountain folds and valley folds in units of bases, thereby facilitating transportation before construction and carrying-in to a construction site.

  The folding structure of the heat radiating panel is such that the fold line between adjacent bases passes through the water pipe in a diagonal direction, and the water pipe is installed in the diagonal direction opposite to the water pipe at the end of the base that forms the fold line. The groove is engraved, and when folded, the bent part of the water pipe is housed in the housing groove to prevent the water pipe from being pulled, or part of the water pipe is straight along the folding line. For example, a structure is proposed in which a straight line portion of a water pipe is prevented from being pulled by being slightly twisted when folded.

In the heat dissipation panel as described above, the bases are connected to each other by routing the water pipes, but in order to reinforce the connection between the bases, in the folding line of the valley fold, the heat dissipation sheet on the front side is connected to the adjacent bases. In the folding and mountain folding line, a sheet-like reinforcing hinge attached to the back side of the heat insulating material is bridged to the adjacent base.

Is done.

  As shown in FIG. 6, the water pipe (2) is inserted into a continuous groove (11) formed in the surface of the heat insulating material (1). As the water flow pipe (2), a resin pipe such as a crosslinked polyethylene pipe, a polybutene pipe, a polypropylene pipe, or a polyethylene pipe is used. Generally, a crosslinked polyethylene pipe or a polybutene pipe is used. The size of the water pipe (2) is such that the outer diameter is usually 4 to 10 mm, preferably 5 to 8 mm, and the inner diameter is usually 4 in order to reduce the pressure loss of the flowing hot water and maintain the average temperature at a higher temperature. -7 mm, preferably 5-6 mm.

  Further, as shown in FIG. 5, a header (9) which is a fluid branching block is used at the edge of the heat insulating material (1), for example, at the lower edge of the lower left corner, using a notch provided in one base. ) Is attached. The header (9) distributes the hot water supplied from a heat source device such as a water heater or a boiler device that produces hot water by gas combustion or electric power to the water pipes (2) (each circulation path) of each system. It is a flow path assembly device for collecting and collecting hot water for collecting hot water circulated in the water pipe (2) and returning it to the heat source device. Said water pipe (2) is connected with the header (9), and is comprised so that the circulation path of 2-8 systems may be comprised according to the magnitude | size of a panel. In addition, each circulation path is provided with the predetermined pattern which circulates through the substantially whole surface of a panel by the combination of the linear part and curved part of a water flow pipe (3).

  The heat radiating sheet (3) (see FIG. 6) is a sheet for transmitting the heat of the hot water of the water flow pipe (2) to the flooring side. The foamed resin molded body and joists constituting each base (1a, 1b,...) It sticks on the front side of the shaped member (5) with an adhesive or a pressure-sensitive adhesive. As the heat dissipation sheet (3), a flexible film or sheet having a thickness of usually 10 μm to 200 μm, preferably 30 μm to 100 μm and excellent in thermal conductivity, such as aluminum foil, tin foil, copper foil, stainless steel A metal foil such as a foil, a metal woven or non-woven fabric, a resin film or a resin sheet, or a laminated sheet obtained by combining these is used.

  In the panel of the present invention, the bases (1a, 1b,...) Are connected by routing the water pipes (3) embedded in the grooves (11) of the heat insulating material (1). 1a, 1b,..., That is, foldable into a mountain fold and a valley fold in the fold line (6) between the bases. The panel illustrated in FIG. 5 has six folding lines (1a, 1b,...) Connected in a row in the length direction of the panel to form a heat insulating material (1), and five folding lines parallel to the panel width. According to (6), it is configured to be folded into ninety-nine folds.

  In addition, although not shown in figure, the panel of this invention may arrange two board | substrates, and the heat insulating material (1) may be comprised, In that case, it can be folded into a mountain fold or a valley fold in a fold line (6). Configured. In the panel of the present invention, the heat insulating material (1) may be configured by arranging two bases in the width direction and a plurality of bases in the length direction. In that case, in the length direction of the panel, Only the two bases on the one end side (two bases arranged in the width direction of the panel) are connected in the width direction of the panel, and the other bases arranged in the length direction of the panel are the two bases. Are connected to the base of each panel in the length direction of each panel. Thus, when folding, the bases arranged in the length direction of the panel are folded into ninety-nine folds for each row, and then the two bases at the end of the panel are folded into the ninety-nine folds. The two base laminates can be stacked into one.

  Moreover, in the panel of this invention, in order to strengthen the connection between the base | substrates (1a, 1b ...) in a fold line (6), as shown in FIG.6 (b), said heat radiating sheet (3) Is attached to the front side of the heat insulating material (1) in a state of being stretched over a folding line (6) folded in a valley fold. Furthermore, as shown to Fig.6 (a), with respect to the folding line (6) folded in a mountain fold, from metal foil, a woven fabric, a nonwoven fabric, a resin film or a resin sheet, or the lamination sheet which combined these, etc. The tape-like reinforcing hinge (4) formed is stuck in a state of being stretched over the back side of the heat insulating material (1).

  As shown in FIG. 5, in the folding line (6), the water pipe (2) is laid across the folding line (6). The part of the water pipe (2) that crosses the folding line is, for example, A skewed portion that is obliquely extended from the base (1a) toward the folding line (6) at an angle that is not orthogonal, a slight parallel portion that follows the folding line (6), and the other from the folding line (6) to the other It consists of the above-mentioned skewed part and the other skewed part extended at substantially the same angle to the base (1b). When the panel is folded by the folding line (6), the parallel structure of the water pipe (2) is slightly twisted when the panel is folded along the folding line (6). It is possible to prevent the occurrence of buckling in the skew portion and the parallel portion.

  Moreover, as shown in FIG.1 and FIG.2, the edge part which mutually adjoins two bases (1a) and (1b) which comprises the site | part which the water pipe (2) of the fold line (6) folded at least in a mountain fold crosses. Is provided with a notch (17) that forms a water pipe accommodation hole (7) in the expanded state of the heat insulating material (1). As shown in FIG. 1, the notches (17) of the bases (1a) and (1b) are, for example, when three water pipes (2) (only the center is indicated by a chain line) crosses the folding line (6). The three recesses having a shape obtained by obliquely cutting the elongated hole in the length portion thereof are configured to be continuous.

  That is, the notches (17) of the bases (1a) and (1b) are respectively connected to the three water pipes (2) when the bases (1a) and (1b) are viewed in a plan view when the panel is unfolded. It is made into the shape which comprises the water pipe accommodation hole (7) which each groove | channel (11) of the base | substrate (1a) and (1b) to accommodate leads, and a water pipe accommodation hole (7) is made of one base | substrate (1a). A width corresponding to the outer diameter of the water pipe (2) with both ends being semicircular and extending from the edge constituting the fold line (6) to the edge constituting the fold line (6) of the other base (1b) The three elongated holes are continuously arranged in parallel in a state of obliquely intersecting the folding line (6), and these are divided by the folding line (6).

  In the panel of this invention, the groove | channel (11) which accommodates a water flow pipe (2) is provided in the front side of the heat insulating material (1), and when there is no above-mentioned notch (17), it is a mountain fold. When folded, the water pipe (2) crossing the fold line (6) is pushed outward by the thickness portion of the base of the groove (11) in the fold line and a tensile force is applied to the water pipe (2). Problems such as detachment from (11) and deformation of the water pipe (2) occur. On the other hand, when the notch (17) is provided at the edge of the base (1a, 1b,...), For example, three notches are inserted into the notch (17) when folded into a mountain fold. Since the water pipe (2) is accommodated, these water pipes (2) are not pushed out, and the tensile force applied to the water pipe (2) can be reduced. In order to reduce the manufacturing cost by standardizing the shape of the base, the notch (17) as described above usually constitutes each folding line (6) that is folded into a mountain fold and a valley fold and passes through the folding line. It is provided at the edge of each base (1a, 1b,...) Where the water pipe (2) intersects.

  In the present invention, in order to prevent the above-mentioned reinforcing hinge (4) from being damaged due to the folding of the panel, as shown in FIG. 4, the water pipe (2) of the folding line (6) (see FIG. 1) folded into a mountain fold. ) On the thickness portions (side end surfaces of the bases) of the two adjacent bases (for example, the base (1a) and the base (1b)) that cross each other, the bases (1a), (1b) The front side corner of the base plate has a structure that is retracted in a direction away from the folding line (6), and in the folded state, a depression (8A) is formed in the connecting portion of the bases (1a) and (1b) (see FIG. 4 (a)). A receding portion (8a) (see FIG. 4 (b)) is provided.

  Similarly, in order to prevent damage to the heat-dissipating sheet (3) due to panel folding, as shown in FIG. 3, the part of the folding line (6) (see FIG. 1) folded by the valley fold crosses the water pipe (2). The two bases (for example, the base (1a) and the base (1b)) adjacent to each other in the thickness portions (side end surfaces of the base) are on the back side of the bases (1a) and (1b). The corner portion has a structure that retreats away from the folding line (6), and in the folded state, a depression (8B) (see FIG. 3 (a)) is formed in the connecting portion of the bases (1a) and (1b). A receding portion (8b) (see FIG. 3 (b)) is provided.

  Specifically, as shown in FIG. 4 (a), when folded into a mountain fold at the fold line (6), the edge of the base (1a) constituting the water pipe accommodation hole (7) on the fold line (6) The thickness portion of the portion is provided with a receding portion (8a) having a structure in which corners on the back side of the base (reinforcing side of the reinforcing hinge (4)) are receded to the inside of the base. Also in the thickness part of the edge of the base (1b) constituting the water pipe accommodation hole (7), the corner of the base back side (reinforcement hinge (4) adhering side) is retreated to the inside of the base. A receding part (8a) is provided. Thereby, as shown in FIG.4 (b), when it folds in a mountain fold with a fold line (6), a base | substrate (1a) and a base | substrate (1b) overlap on the back side, A base | substrate (1a) and (1b) A recess (8A) is formed by each retreating portion (8a). Therefore, when the panel is folded into a mountain fold along the folding line (6), the bent portion (protruding portion) (4c) of the reinforcing hinge (4) protruding toward the water pipe receiving hole (7) is accommodated in the recess (8A). It is possible to prevent competition between the water pipe (2) and the reinforcing hinge (4).

  On the other hand, as shown in FIG. 3 (a), when the folding line (6) is folded into a valley fold, the edge of the base (1a) constituting the water pipe accommodation hole (7) on the folding line (6) The thickness portion is provided with a receding portion (8b) having a structure in which the corner portion on the base surface side (the heat-dissipating sheet (3) adhering side) is receded to the inside of the base material. 7) Also in the thickness portion of the edge of the base (1b) constituting the base, there is a receding portion (8b) having a structure in which corners on the base surface side (the heat radiation sheet (3) sticking side) are receded to the inside of the base. Provided. Thereby, as shown in FIG.3 (b), when it folds in a valley fold with a fold line (6), a base | substrate (1a) and a base | substrate (1b) overlap on the front side, and a base | substrate (1a) and (1b) A recess (8B) is formed by each receding portion (8b). Therefore, when the panel is folded into a valley fold in the fold line (6), the bent portion (protruding portion) of the heat radiating sheet (3) that protrudes to the bent portion side (water conduit containing hole (7) side) of the water conduit (2) ) (3c) can be accommodated in the recess (8B), and competition between the water pipe (2) and the heat radiation sheet (3) can be prevented.

  In order to reduce the manufacturing cost by standardizing the shape of the substrate, the thicknesses of the substrates (1a) and (1b) are usually set to the retreat portion (8b) and Both receding portions (8a) on the back side of the base are provided. Then, the water pipe is formed by the protrusion (80) of the base (1a) and the protrusion (80) of the base (1b) which are formed relative to the above-described thickness portion by the receding portions (8a) and (8b). (2) is restrained from the left and right to suppress the movement. FIGS. 3 and 4 show a portion for restraining one water pipe (2) from the left and right in the water pipe housing hole (7) in FIG. 1 constituted by a notch (17) for convenience of explanation. It is. Further, as the structure of the retreating portions (8a) and (8b) described above, in addition to those formed in steps as shown in the drawing, those formed on inclined surfaces or curved surfaces with chamfered corners may be mentioned. I can do it.

  Moreover, in the thickness part of a base | substrate (1a, 1b ...), the magnitude | size of each retreat part (8a), (8b) is the thickness of a base | substrate (1a, 1b ...), the thickness of a thermal radiation sheet | seat (3). According to the thickness of the reinforcing hinge (4) and the outer diameter of the water pipe (2), the bent portion (3c) of the heat radiation sheet (3) can be sufficiently accommodated in the recess (8B) and the recess (8A). In addition, the bent portion (4c) of the reinforcing hinge (4) can be sufficiently accommodated, and the water pipe (2) can be securely fixed by the left and right protrusions (80).

  Specifically, the width of each receding portion (8a), (8b) along the thickness direction of the base (1a, 1b,...) Is 12 to 35% of the thickness of the base (1a, 1b,...). Designed to a size equivalent to In other words, as shown in FIGS. 3 and 4, in the thickness portion of the edge portion of the base (1a, 1b,...), The protrusions (80) excluding the receding portions (8a) and (8b). ) Thickness (t) to the total thickness of the substrate is set to 25-75%. Further, the depths of the retracted portions (8a) and (8b) along the direction toward the inside of the base (1a, 1b,...) (The method of separating from the folding line (6)) are the depths of the bases (1a, 1b,.・) Designed to have a size corresponding to 10% or more of the thickness.

  The reason why the thickness (t) of the protrusion (80) is defined within the above range is as follows. That is, when the thickness (t) of the protrusion (80) is less than 25% of the total thickness of the base (1a, 1b,...), The force for pressing the water pipe (2) is insufficient, There exists a tendency for a water pipe (2) to float up, and there exists a possibility that a projection part (80) may be damaged by contact with a water pipe (2) by folding and unfolding operation of a panel. On the other hand, when the thickness (t) of the protrusion (80) exceeds 75% of the total thickness of the base (1a, 1b,...), The recess formed by the receding portions (8a), (8b). The widths (8A) and (8B) (the width along the thickness direction of the base) are so narrow that the bent portion (3c) of the heat dissipation sheet (3) and the bent portion (4c) of the reinforcing hinge (4) are formed. It becomes difficult to accommodate.

  Furthermore, even when the depth of the receding parts (8a) and (8b) is less than 10% of the thickness of the base (1a, 1b,...), The panel protrudes into the water pipe receiving hole (7) when folded. The bending allowances of the bent portion (3c) of the heat-dissipating sheet (3) and the bent portion (4c) of the reinforcing hinge (4) cannot be accommodated in the recesses (8B) and (8A). ) And (4c) are easily damaged.

  As described above, in the panel of the present invention, two bases (for example, two bases) constituting the folding pipe (2) of each folding line (6) that is folded into a mountain fold and a valley fold of the heat insulating material (1) (for example, Retracted portions (8b) and (8a) having a structure in which the corners on the base surface side and the back surface side are retreated with respect to the thickness portions of the adjacent edges of 1a) and (1b) are folded. In the meantime, depressions (8B) and (8A) are formed in the connecting portions of the bases (1a) and (1b) (portions crossed by the water pipe (2)). Therefore, when folded into a valley fold, as shown in FIG. 3 (b), the bending of the heat dissipation sheet (3) protruding to the bent portion side of the water pipe (2) (water pipe housing hole (7) side) The portion (3c) can be accommodated in the recess (8B), and when folded into a mountain fold, as shown in FIG. 4 (b), a reinforcing hinge (7) protruding toward the water pipe accommodating hole (7) side The bent portion (4c) of 4) can be accommodated in the recess (8A).

  As a result, according to the present invention, it is possible to reduce the competition between the water pipe (2) crossing the folding line (6), the heat radiating sheet (3), and the reinforcing hinge (4), and these heat radiating sheets (3 ) And the reinforcing hinge (4) can be prevented from being damaged. Therefore, the heat-radiation panel for cooling and heating according to the present invention is easier to handle during transportation and construction. The panel of the present invention can also be applied for cooling by circulating cold water through the water pipe (2).
