Description

  The present invention relates to a heat exchange panel used for floor heating, radiant cooling and heating, and more particularly to a heat exchange panel in which a heat transfer tube for circulating a heat medium is disposed on a plate-like substrate.

  Conventionally, as this type of heat exchange panel, a floor heating panel 100 used in a warm water circulation type floor heating apparatus shown in FIGS. 12A and 12B is known (for example, Patent Document 1).

  12A is a cross-sectional view of the floor heating panel 100, and FIG. 12B is a plan view. As shown in FIG. 12 (A), the floor heating panel 100 includes a plate-like base material 101 in which a pipe groove 102 extending linearly is formed, a heat transfer member 103 fitted in the pipe groove 102, and A heat equalizing plate 104 and a pipe 105 are provided on the plate. The heat transfer member 103 holds the pipe 105 and conducts heat from the pipe 105, has a flat plate portion at both ends, and has a reverse Ω (omega) shape having a recess at the center. Yes. Thus, by providing the heat transfer member 103, the heat from the pipe 105 can be efficiently transferred to the floor.

  When the floor heating panel 100 is installed on the floor surface, as shown in FIG. 12B, a base material 101 on which a straight pipe groove 102 is formed and a base material on which a pipe groove 107 having a bent shape is formed. 106 and the pipe 105 are arranged after that.

JP 2009-52778 A (pages 6-9, FIGS. 2, 8)

  However, in the method of disposing the heat transfer member (103) in the piping groove (pipe groove 107) as in the prior art shown in FIGS. 12A and 12B, it is difficult to process the heat transfer member having a bent shape. Therefore, there was a problem that a heat transfer member could not be provided in the bent portion of the heat transfer tube.

  That is, when a press-molded product is used as the heat transfer member, many types of heat transfer members are required to correspond to the shape of each part of the bent portion, and a die corresponding to each shape is required for the processing. This necessitates increased manufacturing equipment costs and higher manufacturing costs. In addition, using a metal foil that can be easily bent as a heat transfer member and bonding the metal foil to the piping groove, it is very difficult to cut and bond the metal foil to the curved piping groove. Therefore, the cost of assembling and manufacturing becomes high.

  Therefore, in the conventional product, the heat transfer member is provided only in the portion where the heat transfer tube extends linearly, and the heat transfer member is not provided in the bent portion of the heat transfer tube. For example, specifically, a heat transfer member is not provided in the X portion indicated by the alternate long and short dash line circle in FIG. As a result, the heat transfer performance in the bent portion of the heat transfer tube is low, the panel surface temperature of the portion is low, and the surface temperature difference as the whole floor heating panel is large.

  In particular, when a plurality of floor heating panels are used in combination in a single room, a decrease in heat transfer performance at the bent portion of the heat transfer tube is an important problem in terms of comfort. In other words, when a plurality of floor heating panels are installed in combination, a peripheral edge portion of each floor heating panel may be arranged at the center of the room. Since the bent part of the heat transfer tube may be arranged at the peripheral edge part of each floor heating panel, when the multiple floor heating panels are combined, the bent part of the heat transfer tube is not only in the peripheral part of the room but also in the central part. Will be placed. As described above, since the heat transfer member cannot be disposed in the bent portion of the heat transfer tube, the surface temperature of the panel becomes lower than other portions. Thus, if there is a portion having a low panel surface temperature in the central portion of the room, the comfort of heating is impaired.

  The present invention has been made in view of the above circumstances, and its object is to easily process parts and assemble a panel, have high heat transfer performance in a bent portion of a heat transfer tube, and be uniform throughout the panel. An object of the present invention is to provide a heat exchange panel that can perform heating or cooling efficiently and efficiently.

  The heat exchange panel of the present invention includes a flat substrate, a piping groove formed on the surface of the substrate and having a bent portion in the extending direction, and a heat transfer tube disposed therein, and at least the surface of the substrate In the heat exchange panel having a heat equalizing member attached to the heat exchanger, a heat transfer member connected to the heat equalizing member is provided in the bent portion.

  According to the heat exchange panel of the present invention, since the heat transfer member connected to the heat equalizing member is provided in the bent portion of the piping groove, heat transfer of the heat transfer tube in the bent portion can be promoted. As a result, the heat transfer performance equivalent to that of the straight line portion can be ensured even in the bent portion of the heat transfer tube, so that the temperature difference on the panel surface can be reduced and uniform and highly efficient heating or cooling can be achieved.

  In addition, since the heat transfer member is formed with a plurality of separation portions except for at least a part of each connection portion, the heat transfer member can be easily bent according to the bending shape of the piping groove, and can easily be formed in the piping groove. Can be inset. Therefore, the assembly work efficiency of the heat exchange panel can be improved.

  Still further, according to the heat exchange panel of the present invention, the heat transfer member can be easily bent corresponding to each of the different bent portions, so that parts can be shared, Parts can be processed without the need for a mold.

  Hereinafter, a heat exchange panel according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view schematically showing a schematic structure of a heat exchange panel 1 according to the first embodiment of the present invention.

  The heat exchange panel 1 is a floor heating panel laid on the floor of a house. As shown in FIG. 1, the heat exchange panel 1 is laid under a floor finishing material 11 (so-called flooring material), and the heat transfer tubes 3 are arranged in a predetermined pattern on the upper surface of a rectangular flat substrate 2. It arrange | positions, and the soaking | uniform-heating member 7 is adhere | attached so that it may be covered.

  The base material 2 is made of a foamed synthetic resin such as foamed polystyrene, and functions as a heat insulating material that holds the heat transfer tube 3 and prevents heat conduction from the heat transfer tube 3 toward the bottom of the floor. Further, the base material 2 is composed of a plurality of rectangular plate-like bodies, and between each plate-like body of the base material 2, wooden small joists 6 are parallel to each other at a predetermined pitch (for example, 303 mm). Has been placed.

  On the upper surface of the substrate 2, piping grooves 8 for fitting the heat transfer tubes 3 are formed in a predetermined arrangement pattern. The piping groove 8 includes a portion that is arranged in parallel at a predetermined pitch (for example, 75.75 mm) and extends linearly, and a bent portion 8a that curves in the extending direction such as a U-turn portion.

  A heat transfer member 4 that transfers the heat of the heat transfer tube 3 to the heat equalizing member 7 is provided in the linear portion of the pipe groove 8. The heat transfer member 4 has a shape extending linearly. Further, a heat transfer member 5 to be described later is disposed in the bent portion 8 a of the pipe groove 8.

  The heat transfer tube 3 is a heating source of the heat exchange panel 1 and circulates hot water as a heat medium in the tube. Here, a heat source machine (not shown) for supplying hot water is connected to the heat transfer tube 3 via a pipe (not shown). Examples of the hot water heat source include a combustion type water heater and a heat pump type water heater.

  As described above, the heat transfer tube 3 is disposed in the piping groove 8 formed in a predetermined pattern, and a portion that extends in a straight line and a curved portion (corresponding to the bent portion 8a of the piping groove 8) And has a continuous flow path. Further, a plurality of heat transfer tubes 3 (for example, four) are provided, and the hot water branched by a header (not shown) is configured to flow in parallel in the tubes of the heat transfer tubes 3. In addition, the arrangement | positioning shape of the heat exchanger tube 3 shown in FIG. 1 shows the example typically. In the actual product, the arrangement shape of the heat transfer tubes 3 is designed in consideration of the folding of the heat exchange panel 1, the temperature distribution, and the like, and various patterns can be adopted.

  FIG. 2 is a partial enlarged cross-sectional view for explaining the schematic structure of the heat exchange panel 1, and shows a cross section with respect to the extending direction of the piping groove 8 (and the heat transfer tube 3).

  As shown in FIG. 2, the heat exchange panel 1 is laid on a floor base material 12 such as a house. As described above, the floor finishing material 11 is laid on the upper surface of the heat exchange panel 1. Here, the small joists 6 are for fixing the heat exchange panel 1. The small radish 6 is fixed to the floor base material 12 using screws or the like (not shown), and the floor finishing material 11 is fixed to the small radish 6.

  The cross section of the piping groove 8 formed on the upper surface of the base material 2 is substantially U-shaped as shown in FIG. In addition, the cross-sectional shape of the piping groove 8 is not limited to this, For example, a square-shaped recessed groove, the shape which narrowed the width | variety of the inlet part, etc. may be sufficient. Then, the heat transfer member 4 (or a heat transfer member 5 described later) is fitted into the pipe groove 8.

  The heat transfer member 4 conducts heat from the heat transfer tube 3 and transfers it to the heat equalizing member 7, and is a part formed from a metal having good heat conductivity such as aluminum, for example. The heat transfer member 4 is in contact with the outer surface of the heat transfer tube 3 and is connected to the heat equalizing member 7. Thereby, heat transfer from the heat transfer tube 3 is promoted, and the heat passing rate of the heat exchange panel 1 can be improved.

  The heat transfer tube 3 is disposed on the heat transfer member 4 in the pipe groove 8 in which the heat transfer member 4 is fitted. As described above, the heat transfer tube 3 circulates hot water and serves as a heat radiation source for the heat exchange panel 1. The size of the heat transfer tube 3 is, for example, about 4 to 13 mm in inner diameter. The material of the heat transfer tube 3 is, for example, a synthetic resin such as crosslinked polyethylene. Since the synthetic resin pipe has flexibility, the piping work is easy. In addition, the synthetic resin pipe is particularly suitable for the case where the assembly of the pipe is completed and the panel integrated with the pipe is folded and transported. As the heat transfer tube 3, a metal tube such as a copper tube or an aluminum tube may be used. A metal tube is advantageous in terms of heat transfer performance because of its high thermal conductivity.

  On the pipe groove 8 in which the heat transfer tube 3 is fitted, a heat equalizing member 7 is stuck so as to cover the entire upper surface of the base material 2. The heat equalizing member 7 conducts heat from the heat transfer tube 3 and uniformly heats the surface of the heat exchange panel, and is, for example, a metal foil such as aluminum. The soaking member 7 also functions as a connecting member for connecting a plurality of plate-like bodies and small joists 6 constituting the substrate 2.

  The soaking member 7 is a rectangular sheet material in which an adhesive is applied to one surface in advance, and the thickness thereof is, for example, 0.04 mm. The entire upper surface of the heat exchange panel 1 is covered by arranging a plurality of the rectangular sheet materials and bonding them together. Thus, the heat exchange panel 1 can be easily assembled by using a plurality of sheet materials. Since the soaking member 7 is very thin as described above, there is no problem in the dimensions of the product even if there is an overlapping portion between adjacent sheet materials. Moreover, it replaces with the method of comprising the soaking | uniform-heating member 7 using several sheets of material, the soaking | uniform-heating member 7 is comprised from one sheet material, and the whole upper surface of the heat exchange panel 1 is formed with the one sheet material. It is good also as covering.

  Next, with reference to FIGS. 3A and 3B, the structure around the bent portion 8a where the heat transfer tube 3 is curved and arranged will be described in detail. FIG. 3A is a plan view showing a schematic structure around the bent portion 8a of the piping groove 8, and FIG. 3B is a partially enlarged cross-sectional view showing a cross section taken along the line AA.

  As shown in FIGS. 3A and 3B, the heat transfer member 5 is provided on the curved portion of the heat transfer tube 3, that is, the bent portion 8 a of the pipe groove 8. The heat transfer member 5 conducts heat from the heat transfer tube 3 and transfers it to the heat equalizing member 7 in the same manner as the heat transfer member 4 described above.

  As shown in FIG. 3 (B), the cross-sectional shape of the piping groove 8 is the same shape as the above-mentioned linear part also in the bending part 8a, and has substantially U shape. The heat transfer member 5 is fitted into the bent portion 8 a of the pipe groove 8. Further, the heat transfer tube 3 is fitted on the heat transfer member 5, and the heat equalizing member 7 is further bonded thereon.

  The heat transfer member 5 is a part manufactured by press-molding a metal material plate having a high thermal conductivity such as an aluminum plate, for example, and has a cross-sectional shape which will be described later. 1 mm.

  Further, the heat transfer member 5 has an insertion portion 5 a having a substantially U-shaped cross section corresponding to the shape of the piping groove 8. More specifically, in the cross-sectional shape, the vicinity of the bottom of the insertion portion 5a has a semicircular shape corresponding to the outer surface of the heat transfer tube 3, and the side surface of the insertion portion 5a is substantially equal to the radius of the heat transfer tube 3. It is represented by a straight portion having a length. And as above-mentioned, the insertion part 5a is inserted in the piping groove 8, and the concave surface of the upper surface side of the insertion part 5a, ie, the part which comprises a cross-sectional semicircle shape, is the outer surface of the heat exchanger tube 3 inserted there Touch.

  Here, it is also possible to set the outer width dimension of the insertion portion 5 a of the heat transfer member 5 to be slightly larger than the width dimension of the piping groove 8, and to provide an appropriate tightening allowance with the base material 2. Further, the inner width dimension of the insertion portion 5 a may be set slightly smaller than the diameter of the heat transfer tube 3, and an appropriate tightening allowance may be provided between the heat transfer tube 3. Thereby, since the detachment of the heat transfer member 5 and the heat transfer tube 3 can be prevented, the assembly work efficiency can be improved. Moreover, since the adhesiveness between the heat transfer member 5 and the heat transfer tube 3 is increased, the heat transfer performance is also improved.

  Moreover, it has the flat plate part 5b formed in the both-sides edge part of the insertion part 5a continuously with the insertion part 5a. The lower surface of the flat plate portion 5b, that is, the surface on the insertion portion 5a side is in contact with the base material 2, and the upper surface is bonded to the heat equalizing member 7.

  Thus, the heat transfer member 5 contacts at least a portion of the outer surface of the heat transfer tube 3 and is connected to the heat equalization member 7, so that heat from the heat transfer tube 3 is conducted through the heat transfer member 5 and is equalized. It flows to the heat member 7. Specifically, the heat transfer member 5 is in contact with the lower surface of the heat transfer tube 3, conducts heat from the lower surface of the heat transfer tube 3 to the heat equalizing member 7 on the upper surface side of the heat exchange panel 1. Tell. Thereby, also in the bending part 8a, since the heat transfer from the heat exchanger tube 3 can be accelerated | stimulated similarly to a linear part, it becomes possible to heat the surface of the heat exchange panel 1 uniformly, and a heat exchange panel. 1 can be further improved.

  Further, as shown in FIG. 3A, the heat transfer member 5 is formed with separation portions 5d and 5e. Thereby, the heat transfer member 5 can be formed as a part extending linearly and can be easily bent in accordance with the bending shape of the pipe groove 8 when being mounted on the pipe groove 8. Details will be described later.

  Here, as shown in FIG. 3B, in the bent portion 8a of the piping groove 8, the surface on the bending center direction side is the inner side surface 8b, and the surface on the outer side in the bending radial direction is the outer surface 8c. (Hereinafter, the inner side 8b side is referred to as “inner side 8b” and the outer side surface 8c side is referred to as “outer side 8c” when viewed from the center of the piping groove 8 (the central axis of the heat transfer tube 3)).

  Next, with reference to FIG. 4 (A) thru | or (C), the heat-transfer member 5 is demonstrated in detail. 4A is a plan view showing a schematic structure of the heat transfer member 5, FIG. 4B is a partially enlarged cross-sectional view showing a cross section taken along the line BB, and FIG. It is a partial expanded sectional view which shows the cross section of the connection part 5c in the separation parts 5d and 5e part.

  The heat transfer member 5 has a cross-sectional shape shown in FIG. 4B, that is, an insertion portion 5a having a substantially U shape, and a flat plate portion 5b formed continuously at both ends of the insertion portion 5a. It has a plurality of small pieces 5f that extend in a straight line in the direction perpendicular to the drawing sheet. The plurality of small pieces 5f are connected by a connecting portion 5c as shown in FIGS. 4A and 4C, and the heat transfer member 5 as a whole is linear in the direction perpendicular to the plane of FIG. 4B. Form that extends to. That is, the heat transfer member 5 is an integral part connected by the connecting portion 5c.

  The connection part 5c is comprised from the metal tape made from aluminum with which the adhesive was apply | coated to the whole surface (it has an adhesion part). A metal tape such as aluminum is preferable in terms of heat transfer performance because of its high thermal conductivity. And the heat-transfer member 5 is comprised by adhere | attaching and connecting each small piece 5f with the metal tape which connected one.

  Here, the pressure-sensitive adhesive (pressure-sensitive adhesive portion) is not limited to a high-viscosity liquid bonding agent that does not involve curing, but also includes various adhesives that involve curing such as reaction systems and solution systems. That is, any material that can easily join the metal tape and the small piece 5f may be used. For example, a hot melt adhesive may be used.

  Moreover, the thickness of the connection part 5c, ie, the thickness of a metal tape, is 0.04 mm, for example. Instead of the above-described metal tape, other types of adhesive tape members such as synthetic resin and cloth may be used as the connecting tape member constituting the connecting portion 5c.

  As shown in FIGS. 4A and 4C, the heat transfer member 5 connected by the metal tape has a separation portion 5d from the inner side 8b and an outer side 8c as regions between the small pieces 5f. Separating portions 5e are formed respectively.

  Thus, since the separation parts 5d and 5e are formed in the heat transfer member 5, as shown in FIG. 4 (A), according to the bending shape of the piping groove 8 (see FIG. 1 and the like) Can be bent easily. Specifically, the width of the separating portion 5d serving as the inner side 8b of the bending is narrowed, the flat plate portion 5b is overlapped, and the width of the separating portion 5e serving as the outer side 8c of the bending is widened. Here, as described above, since the thickness of the heat transfer member 5 is about 0.1 mm, which is very thin compared to the thickness of the base material 2 and the like, the overlap of the flat plate portion 5b on the inner side 8b is a problem in terms of product dimensions. Not.

  As described above, since the separation portions 5d and 5e are regions between the small pieces 5f, the width of the separation portions 5d and 5e can be adjusted by adjusting the separation distance of the small pieces 5f. For example, the width of the separation portions 5d and 5e is preferably about 2 to 3.5 mm. Thereby, bending can be easily performed by reducing the overlap of the flat plate portion 5b on the inner side 8b of the bending. Moreover, since the area of the flat plate part 5b used as the outer side 8c of a bending can fully be ensured, it is suitable also from the surface of heat transfer. As described above, the overlap of the flat plate portion 5b does not cause a problem in the dimensions of the product. Therefore, the small pieces 5f are arranged as close to each side as possible so as to further reduce the width of the separating portions 5d and 5e. You may comprise.

  A plurality of separation portions 5d and 5e are formed in the extending direction of the heat transfer member 5 with a predetermined arrangement interval. Here, the said arrangement | positioning space | interval is the distance between the separation parts 5d and 5e and the adjacent separation parts 5d and 5e, and is decided by the extension direction length of the small piece 5f. The predetermined arrangement interval is, for example, about 5 to 20 mm, and the length of the small piece 5f may be about 5 to 20 mm. In the present embodiment, the length in the extending direction of the small piece 5f, that is, the arrangement interval of the separating portions 5d and de is 15 mm. Thereby, the operation | work which mounts the heat-transfer member 5 to the piping groove 8 can be performed easily, and efficient heat transfer can be performed.

  In addition, the width | variety and arrangement | positioning space | interval of the separation parts 5d and 5e mentioned above do not necessarily need to be equal. For example, the arrangement intervals and widths of the separating portions 5d and 5e can be changed in a predetermined pattern by combining small pieces 5f having different lengths or by connecting them with different separation distances.

  Specifically, the heat transfer member 5 is used continuously from the bent portion 8a (see FIG. 1 and the like) of the piping groove 8 to the straight portion, and in the portion inserted into the bent portion 8a, the separating portion 5d, The width of 5e is widened, and the arrangement interval is narrowed. On the other hand, in the portion inserted into the straight portion, the width of the separation portions 5d and 5e is narrowed and the arrangement interval is widened. By adopting such a configuration, the heat transfer member 5 can be easily handled, and the assembly work efficiency can be further improved.

  In addition, as shown in FIG. 4C, in the present embodiment, the connecting portion 5c is provided at the approximate center of the cross section of the insertion portion 5a. That is, the connecting portion 5c is formed in the vicinity of the center of the curved surface having a semicircular cross section near the bottom of the insertion portion 5a having a substantially U-shaped cross section. Therefore, the separation portions 5d and 5e on the inner side 8b and the outer side 8c are formed so as to separate all the flat plate portions 5b on both sides and reach the vicinity of the bottom at the center of the insertion portion 5a.

  Thus, by providing the connection part 5c near the center of the cross section of the insertion part 5a, the heat transfer member 5 can be bent in both the left and right directions. Thereby, the assembly work efficiency of the heat exchange panel 1 can be improved.

  Moreover, the metal tape used as the connection part 5c is affixed on the concave surface of the insertion part 5a. That is, the metal tape is affixed to the radially inner surface (the upper surface in FIG. 4C) in the vicinity of the bottom of the insertion portion 5a having a semicircular cross section. Thereby, the affixing operation of the metal tape can be performed efficiently.

  Moreover, the heat-transfer member 5 can be processed as a common part having a linear shape, and can be easily bent according to various bending shapes after the processing. Therefore, a large number of molds corresponding to various bending shapes are not required, and the processing can be easily performed as a linear common part. The processing method will be described later.

  In addition, since the connection part 5c should just connect at least one part of each small piece 5f, it is good also as providing the connection part 5c in the other part different from the above-mentioned example.

  Moreover, you may form the convex shape for preventing the detachment | attachment of the heat exchanger tube 3 in the side surface at the side by which the heat exchanger tube 3 (refer FIG. 1 etc.) of the insertion part 5a is inserted. Furthermore, you may form the width | variety of the entrance part of the insertion part 5a slightly narrower than the width | variety of the heat exchanger tube 3. FIG. By these, since it can prevent that the inserted heat exchanger tube 3 remove | deviates, the assembly of the heat exchange panel 1 becomes still easier.

  Next, as a modification of the embodiment of the present invention, the heat transfer members 25, 35, 45, 55, 65 and the heat exchange panel 71 according to the second to seventh embodiments will be described in detail with reference to FIGS. Explained. In addition, in FIG. 5 thru | or FIG. 10, about the component which has the same or same operation | movement as the heat exchange panel 1 which already demonstrated 1st Embodiment, and an effect, the same code | symbol is used, The description is abbreviate | omitted, Only differences from the first embodiment will be described in detail.

  FIG. 5A is a plan view showing a schematic structure of a heat transfer member 25 according to the second embodiment of the present invention, and FIG. 5B is a partially enlarged cross-sectional view showing a cross section taken along the line DD. C) is a partial enlarged cross-sectional view showing a cross section along the line EE, that is, at the separation portions 5d and 5e.

  In the heat transfer member 25 according to the present embodiment, the connecting portion 25c is integrally formed from the same material as the insertion portion 5a and the flat plate portion 5b by press molding or the like. This is a difference from the heat transfer member 5 (see FIG. 4) according to the first embodiment described above.

  Specifically, as shown in FIG. 5 (A), the heat transfer member 25 has a cross-sectional shape shown in FIG. 5 (B) and is a part that extends linearly in the direction perpendicular to the paper surface of FIG. It is processed and formed by pressing or the like.

  Then, as shown in FIGS. 5A and 5C, the heat transfer member 5 processed by press working or the like has a cut (hereinafter referred to as “cut 5d” as appropriate) that becomes the separation portion 5d from the inner side 8b. In addition, cuts (hereinafter referred to as “cuts 5e” as appropriate) are formed from the outer side 8c to become the separation portions 5e. A plurality of the cuts 5d and 5e are formed in the extending direction of the heat transfer member 25 at a predetermined arrangement interval (for example, about 5 to 20 mm).

  As shown in FIG. 5C, the cuts 5d and 5e are formed leaving at least a portion of the connecting portion 25c. Thus, even after the cuts 5d and 5e are formed, the heat transfer member 25 is an integral part connected by the connecting part 25c without being cut apart by the cut parts 5d and 5e.

  Thus, the heat transfer member 25 according to the present embodiment can be processed as a linear integral part from the material to the completion of the part by press molding or the like. Therefore, compared to the heat transfer member 5 according to the first embodiment in which a metal tape is used for the connecting portion 5c (see FIG. 4) and a plurality of small pieces 5f (see FIG. 4) are connected with the metal tape, the processing is automated. Is easy, and can be processed more efficiently and at high speed. The processing method will be described later.

  6A is a plan view showing a schematic structure of the heat transfer member 35 according to the third embodiment, FIG. 6B is a partially enlarged cross-sectional view showing a cross section taken along the line FF, and FIG. , GG line, i.e., a partial enlarged cross-sectional view showing a cross section at the notches 5d and 5e.

  As shown in FIG. 6C, in the heat transfer member 35 according to the present embodiment, the connecting portion 35c is provided on the side surface portion that is the insertion portion 5a portion and is the inner side 8b of the bending. This is the difference from the first and second embodiments described above. In the present embodiment, as in the second embodiment, the connecting portion 35c is integrally formed from the same material as the insertion portion 5a and the flat plate portion 5b by pressing or the like.

  In the heat transfer member 35, the connecting portion 35c is provided not on the curved surface portion having a semicircular cross section in the vicinity of the bottom of the insertion portion 5a having a substantially U-shaped cross section but on the flat portion on the side surface. That is, the notch 5d on the inner side 8b is formed so as to cut substantially the entire flat plate portion 5b on the inner side 8b, and the notch 5e on the outer side 8c is formed so as to reach the inner side 8b of the insertion portion 5a.

  In this way, by leaving the connecting portion 35c on the side surface of the insertion portion 5a which is the inner side 8b of the bending, the heat transfer member 35 is in the bending direction, that is, in the horizontal direction in FIG. 6C and in the same drawing (A). Bends easily in the bending direction shown. On the other hand, with respect to the direction of insertion into the piping groove 8, that is, the vertical direction in FIG. 6C, the rigidity of the heat transfer member 35 can be secured high, and bending can be made difficult. Moreover, the malfunction that the heat-transfer member 35 will be cut | disconnected by the notches 5d and 5e part can also be prevented. As a result, the heat transfer member 35 can be easily handled, and the fitting operation into the piping groove 8 can be easily performed, so that the assembly work efficiency of the heat exchange panel 1 can be increased.

  FIG. 7A is a plan view showing a schematic structure of a heat transfer member 45 according to the fourth embodiment of the present invention, and FIG. 7B is a partially enlarged cross-sectional view showing a cross section taken along the line HH. C) is a partial enlarged cross-sectional view showing a cross section taken along line I-I, that is, the cuts 45d and 5e.

  In the heat transfer member 45 according to the present embodiment, the basic configuration is the same as that of the third embodiment described above, and the notch 45d serving as the inner side 8b of the bending is formed wider than the notch 5e on the outer side 8c. This is the difference from the heat transfer member 35 (see FIG. 6) according to the third embodiment described above.

Specifically, as shown in FIG. 7A, the cut 45d has an opening that is wider than the cut 5e and is formed in a substantially V shape. Thereby, when the heat transfer member 45 is bent, it is possible to prevent the flat plate portions 5b serving as the inner side 8b of the bending from overlapping the adjacent flat plate portions 5b.
As a result, the heat transfer member can be bent more easily, and the assembly work efficiency of the heat exchange panel 1 can be further improved.

  Moreover, since the shape of the cut 45d is substantially V-shaped, it is possible to ensure a large area of the flat plate portion 5b while preventing the flat plate portion 5b from overlapping. Thereby, the fall of the heat-transfer performance of the heat-transfer member 45 can be suppressed. Note that the shape of the cut 45d is not limited to a V-shape, and if it is formed so that at least the flat plate portion 5b does not overlap, workability during bending can be improved.

  Further, as in the first and second embodiments, the connecting portion 5c (see FIG. 4) is provided near the center of the cross section of the insertion portion 5a, and the notch 5e that becomes the outer 8c is similarly formed in a substantially V shape. You may do it. Thereby, in the structure which enabled the bending to both sides, the overlap of the flat plate part 5b can be prevented, the bending process to both sides can be made easy, and work efficiency can be improved.

  FIG. 8A is a plan view showing a schematic structure of a heat transfer member 55 according to the fifth embodiment of the present invention, and FIG. 8B is a partially enlarged cross-sectional view showing a cross section taken along line JJ. C) is a partial enlarged cross-sectional view showing a cross-section at the KK line, that is, the notch 5e portion.

  As shown in FIGS. 8A to 8C, in the heat transfer member 55 according to this embodiment, the basic configuration is the same as that of the above-described third embodiment, and a flat plate is formed on the side edge portion that becomes the inner side 8b of the bending. The part 5b is not provided. This is the difference from the heat transfer member 35 (see FIG. 6) according to the third embodiment described above.

  That is, as shown in FIG. 8B, the heat transfer member 55 includes an insertion portion 5a having a substantially U-shaped cross section and an edge of the insertion portion 5a that becomes the outer side 8c of the bend when the heat transfer member 55 is bent. And a flat plate portion 5b formed continuously in the portion. Then, as shown in FIG. 8C, a cut 5e is formed from the outer side 8c to the side surface that becomes the inner side 8b of the insertion portion 5a, and the connecting portion 35c remains on the side surface that becomes the inner side 8b of the insertion portion 5a.

  With such a configuration, the heat transfer member 55 can be bent more easily, and the assembly workability of the heat exchange panel 1 can be further enhanced. Further, the material cost of the heat transfer member 55 can be reduced.

  When the heat transfer tube 3 (see FIG. 1 and the like) is arranged, the vicinity of the outside 8c of the bent portion 8a (see FIG. 1 and the like) has a long distance from the adjacent heat transfer tube 3, and the surface temperature of the heat exchange panel 1 This is a region where it tends to be low. Since the heat transfer member 55 according to the present embodiment is provided with the flat plate portion 5b only on the outer side 8c of the bending, the effect of making the surface temperature of the heat exchange panel 1 uniform can be obtained.

  FIG. 9A is a plan view showing a schematic structure of a heat transfer member 65 according to the sixth embodiment of the present invention, and FIG. 9B is a partially enlarged cross-sectional view showing a cross section taken along line LL. C) is a partial enlarged cross-sectional view showing a cross section at the line MM, that is, at the notches 5d and 5e.

  In the heat transfer member 65 according to the present embodiment, the connecting portion 65c is constituted by a connecting tape member as in the first embodiment, and the connecting portion 65c is inserted into the insertion portion as in the third to fifth embodiments. It is formed on the side surface of 5a.

  Specifically, as shown in FIGS. 9B and 9C, a small piece 5f of a heat transfer member 65 that is molded into a predetermined cross-sectional shape and cut shortly, is applied with an adhesive on one side. The heat transfer member 65 is configured by bonding and connecting each with a metal tape made of metal. That is, as shown in FIG. 9C, in the present embodiment, the connecting metal tape becomes the connecting portion 65c. In addition, the thickness of the connection part 65c is 0.04 mm, for example. In addition, the connecting portion 65c is provided on the side surface of the insertion portion 5a serving as the inner side 8b of the bending, as in the third to fifth embodiments described above.

  Even with such a configuration, the heat transfer member 65 connected and integrated by the connecting portion 65c has a form in which a plurality of separating portions 5d and 5e are formed, leaving the connecting portion 65c. As with the fifth embodiment, it can be bent easily.

  FIG. 10 is a partial enlarged cross-sectional view showing a schematic structure of a heat exchange panel 71 according to the seventh embodiment of the present invention.

  In the heat exchange panel 71 according to the present embodiment, the heat equalizing member 77 is not covered on the heat transfer tube 3. This is the difference from the heat exchange panel 1 according to the first embodiment described above (see FIG. 1 and the like).

  That is, as shown in FIG. 10, the heat equalizing member 77 is bonded to the flat plate portion 5 b of the heat transfer member 5, and the edge is bent and bonded to the insertion portion 5 a of the heat transfer member 5. In the present embodiment, the heat equalizing member 77 is bonded to the upper surfaces of the base member 2 and the heat transfer member 5 before the heat transfer tube 3 is disposed in the pipe groove 8. Thereby, the heat exchange panel 71 after sticking the soaking | uniform-heating member 77 will be in the state which the upper part of the piping groove 8 opened.

  The heat equalizing member 77 is bonded so that the peripheral edge matches the position of the piping groove 8. As another method, after applying the heat equalizing member 77 so as to cover the pipe groove 8 portion, the portion corresponding to the pipe groove 8 of the heat equalizing member 77 may be cut. Further, a perforation may be formed in advance in a portion corresponding to the piping groove 8 of the heat equalizing member 77.

  In addition, by making the soaking | uniform-heating member 77 contact the insertion part 5a of the heat-transfer member 5, heat dissipation from the heat exchanger tube 3 can be accelerated | stimulated, but without connecting the soaking | uniform-heating member 77 to the insertion part 5a. It is also possible to adopt a configuration in which only the flat plate portion 5b is adhered.

  By adopting the configuration described above, the heat exchange panel 71 to which the heat transfer tubes 3 are not assembled can be assembled in advance at the factory, and only the heat transfer tubes 3 can be arranged at the construction site. As a result, the floor heating panel of the on-site piping construction method can also promote the heat transfer of the bent portion of the heat transfer tube 3 and increase the panel surface temperature without increasing the work load on the site. it can. Of course, it is possible to perform all assembly operations including the operation of fitting the heat transfer member 5 into the base material 2 on site.

  It is also possible to cover the upper part of the heat transfer tube 3 by further attaching a metal foil such as aluminum such as a heat equalizing member 77 to the uppermost surface of the heat exchange panel 71 after the heat transfer tube 3 is disposed. is there. By doing so, the heat transfer performance of the heat exchange panel 71 can be further improved.

  Next, the manufacturing method of the heat transfer member 5 will be described in detail. First, an example of the first manufacturing method will be described with reference to FIGS. 11 (A) and 11 (B). FIG. 11 (A) is a plan view schematically showing the method for manufacturing the heat transfer member 5 according to the first embodiment of the present invention, and FIG. 11 (B) shows a cross section along the line NN. It is sectional drawing.

  First, as a processing material, for example, an aluminum rolled material (material Z) formed in a substantially strip shape having a width of about 15 mm and a thickness of about 0.1 mm is used. The material Z having a substantially strip shape is a so-called hoop material supplied by being wound in a coil shape.

  In the first step (S0), as shown in FIG. 11A, a material Z, which is a rolled aluminum material, is arranged on the upper surface of the base die 81 (die) at a predetermined interval. Here, the separation distance between the materials Z is the width dimension of the separation portions 5d and 5e of the heat transfer member 5 after completion. Further, the width dimension of the material Z is the length dimension of the small piece 5f of the heat transfer member 5 after completion, that is, the arrangement interval of the separating portions 5d and 5e. As described above, the widths and arrangement intervals of the separating portions 5d and 5e are not necessarily equal, and may be formed in a predetermined pattern according to the purpose.

  As shown in FIG. 11B, a plurality of mold grooves 81a having a substantially U-shaped cross section are formed in the base mold 81 at a predetermined interval (pitch). The predetermined pitch is substantially the same as the width of the heat transfer member 5 after completion. And as shown to the same figure (A), the linear material Z is arrange | positioned so that it may extend in the orthogonal | vertical direction with respect to the extending direction of the type | mold groove 81a. The material Z disposed on the upper surface of the base mold 81 may be temporarily fixed using, for example, an adhesive tape at the right end of the sheet. Thereby, the shift | offset | difference of the material Z at the time of press work can be prevented.

  In the second step (S01), a press die 82 (punch) is pressed from above the material Z toward the die groove 81a of the base die 81 to form a substantially U-shaped cross section as shown in FIG. The insertion portion 5a is formed (bending step). Here, the recess having a substantially U-shaped cross section serving as the insertion portion 5a is formed so as to extend in a direction perpendicular to the longitudinal direction (extending direction) of the material Z extending linearly.

  Further, the insertion portion 5a is formed in order from the right side of the drawing with respect to the material Z. As a result, when the insertion portion 5a is processed, it is allowed to draw the left side portion of the material Z into the mold groove 81a, so that processing problems such as material cracking can be prevented.

  In a 3rd process (S02), the metal tape made from aluminum which comprises the connection part 5c is affixed on the concave surface of the insertion part 5a shape | molded by the above-mentioned bending process S01 (connection process). Thereby, the materials Z arranged at a predetermined arrangement interval are connected by the metal tape. As described above, the metal tape is attached to the concave surface, that is, the upper surface of the insertion portion 5a and near the center of the cross section. For this reason, the work of attaching the metal tape can be performed efficiently.

  In the fourth step (S03), the connected material Z is cut by the cutter 83 (cutting step). Thereby, the small piece 5f is cut out from the material Z, and the heat transfer member 5 is completed. The material cutting method is press shearing using a linear cutting tool, but a rotating disk cutter or the like may be used as the cutting tool.

  In the fifth step (S04), the completed heat transfer member 5 is taken out from the base mold 81 (takeout step).

  In this way, the heat transfer member 5 can be easily processed from the aluminum rolled material having a substantially band shape. In addition, as described above, the completed heat transfer member 5 can be easily bent corresponding to various bending shapes of the piping groove 8 (see FIG. 1 and the like), so that various types of bending corresponding to different bending shapes can be performed. There is no need for a mold, and only a linear bending mold is sufficient. Therefore, manufacturing equipment costs for parts processing can be reduced.

  Note that, as indicated by the arrow Y, the material Z may be moved together with the base mold 81 from the left side to the right side of the page, and the above steps S01 to S04 may be performed continuously. By doing so, the heat-transfer member 5 can be produced efficiently. In addition, regarding each of the above-described steps S01 to S04, after all the steps are completed, the next step may be performed. That is, after processing of all the insertion portions 5a is completed in the bending process S01, the process proceeds to the next connection step S02, and after all the connections are completed, the process proceeds to the next cutting process S03 to perform cutting. .

  Moreover, it is also possible to perform processing by changing the order of the bending step S01 and the connecting step S02. That is, the material Z arranged at a predetermined interval on the upper surface of the base die 81 in the first step (S0) may be first connected with an aluminum metal tape constituting the connecting portion 5c (connecting step S02). ). After that, the press die 82 is pressed from above the material Z toward the die groove 81a of the base die 81 to form the insertion portion 5a having a substantially U-shaped cross section (bending step S01). Thereby, since a metal tape is affixed with respect to the planar material Z, the tape affixing operation | work of connection process S02 can be performed easily. The position where the metal tape to be the connecting portion 5c is attached is determined in consideration of deformation due to bending so that the connecting portion 5c is substantially at the center of the insertion portion 5a after the bending step S01.

  Next, an example of the second manufacturing method will be described as another example of the manufacturing method with reference to the form of the heat transfer member 25 shown in FIGS. The second manufacturing method is a method of integrally processing the connecting portions 25c and 35c (see FIG. 6 and the like) with the same material as the insertion portion 5a and the flat plate portion 5b as in the second to fifth embodiments. It is an example.

  First, as a processing material, for example, a hoop material of aluminum rolled material formed into a substantially strip shape having a width of about 40 mm and a thickness of about 0.1 mm is used.

  In the first step, the hoop material of the aluminum rolled material is continuously supplied to the shearing machine to form incisions 5d and 5e that are directed inward from the side edge portions of the substantially strip-shaped material (incision step). The processing method of the cuts 5d and 5e is press shear processing using a punch and a die, which is so-called press cutting processing. At this time, productivity can be improved by simultaneously processing the plurality of cuts 5d and 5e. Note that a rotating disk type cutter or the like may be used as the cutting tool.

  Next, as a second step, the material to be processed on which the cuts 5d and 5e are formed is supplied to a cutting machine and cut into a predetermined length (cutting step). The material cutting method is press shearing as in the above-described cutting step. The predetermined length is a length corresponding to the extending length of each bent portion 8a (see FIG. 1 and the like). Of course, the cutting process and the cutting process may be performed by a common processing machine.

  In the third step, the work material cut to a predetermined length is supplied to a bending machine and bent into a predetermined cross-sectional shape as shown in FIG. 5B (bending step). The bending is performed by press bending using a die (punch and die) extending linearly with a predetermined cross-sectional shape. The linear mold can be used in common for the heat transfer members 25 having different lengths. By this step, the heat transfer member 25 extending in a straight line with a predetermined cross-sectional shape is completed.

  In this manner, the heat transfer member 25 can be easily processed from the aluminum rolled material having a substantially band shape. In addition, as described above, the completed heat transfer member 25 can be easily bent in accordance with various bending shapes of the piping groove 8 (see FIG. 1 and the like), so that various types of bending shapes corresponding to different bending shapes can be obtained. There is no need for a bending mold, and only a linear bending mold is sufficient. Therefore, manufacturing equipment costs for parts processing can be reduced.

  Next, as another example of the method for manufacturing the heat transfer member 25, an example of a third manufacturing method will be described. The third manufacturing method is also a method of integrally processing the connecting portions 25c and 35c (see FIG. 6 and the like) with the same material as the insertion portion 5a and the flat plate portion 5b as in the second to fifth embodiments. It is an example.

  Also in the example of the third manufacturing method, an aluminum hoop material rolled into a substantially strip shape is used as the processing material, as in the examples of the first and second manufacturing methods described above. The width of the material is about 40 mm as in the second manufacturing method.

  In the first step, a substantially strip-shaped material is continuously supplied to a roll forming machine and formed into a predetermined cross-sectional shape as shown in FIG. 5B (roll forming step). The roll forming machine includes a plurality of mold rollers each having a different shape so as to be molded in multiple stages from a raw material to a finished product, and the mold rollers are sequentially arranged in the material feeding direction. The substantially band-shaped material supplied to the roll forming machine is gradually deformed by passing through the plurality of mold roller portions, and is continuously formed to the final shape.

  In the second step, the material to be processed having a predetermined cross-sectional shape is continuously supplied to the shearing machine, and as shown in FIG. 5 (A), it goes inward from the side edge portion of the flat plate portion 5b. Cuts 5d and 5e are formed (cut process). The processing method of the notches 5d and 5e is the same as the example of the second manufacturing method.

  Next, as a third step, the material to be processed on which the cuts 5d and 5e are formed is supplied to a cutting machine and cut into a predetermined length (cutting step). Of course, both the cutting process and the cutting process may be performed by one machine. The heat transfer member 25 is completed through the above steps.

  Thus, according to the example of the 2nd manufacturing method using roll forming, since all the processes to a final process can be performed continuously, the productivity of parts can further be raised.

  As described above, the floor heating panel has been described as an example of the embodiment of the present invention. However, the heat exchange panel of the present invention is not limited to the floor heating application, and is a panel having a heat transfer tube for circulating a heat medium. As a heat exchanger, it can be used for other purposes.

  Moreover, although hot water was demonstrated as an example as a heat medium which flows through the inside of the heat exchanger tube 3, in addition to the heat medium using sensible heat, such as hot water, cold water, and brine, the latent heat accompanying the phase change is used as the heat medium. It is also possible to use other heat medium such as a refrigerant. Even in such a case, according to the heat exchange panel of the present invention, heat transfer at the bent portion of the heat transfer tube is promoted, and uniform and highly efficient heating or cooling can be performed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this. Various modifications can be made without departing from the scope of the present invention.
