  In addition, in the present invention, the plate-like fin and the heat collecting tube may be integrally formed by welding, but preferably, the plate-like fin and the heat collecting tube are formed of an aluminum extruded shape. (Claim 10).

  With this configuration, it is possible to easily produce a heat collection panel having high thermal conductivity and high dimensional accuracy.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail based on an accompanying drawing. Here, the case where a part of solar power generation heat collecting composite panel which concerns on this invention is applied, for example to a solar heat collector is demonstrated.

  As shown in FIG. 1, a photovoltaic power generation and heat collecting composite panel 1 (hereinafter referred to as a composite panel 1) according to the present invention includes a solar cell module 2 and a plurality of (drawing) juxtaposed on the back side of the solar cell module 2. Then, the heat collecting panel 10 is shown), and the header tube 3 connected to the end of the heat collecting tube 12 constituting the heat collecting panel 10 is provided. In addition, the terminal box 2a for converting the light energy which the solar cell module 2 received from sunlight into electricity is arrange | positioned at the back surface side of the solar cell module 2. FIG. The surface of the solar cell module 2 is covered with windproof glass as necessary. When windproof glass is attached, the heat collection effect can be improved.

  As shown in FIGS. 5 to 7, the heat collecting panel 10 includes a plate-like fin 11 joined to the back surface of the solar cell module 2 and a longitudinal direction of the plate-like fin 11 on the non-joint surface side of the plate-like fin 11. The heat collecting pipes 12 whose both ends protrude outward from the plate-like fins 11 are integrally formed. In this case, the heat collecting tube 12 is formed integrally with the plate-like fin 11 via a rib 13 that stands at the center of the surface of the plate-like fin 11. The plate-like fins 11, the heat collecting tubes 12 and the ribs 13 are integrally formed of an extruded shape made of an aluminum alloy. After being extruded, both end portions in the longitudinal direction of the plate-like fins 11 and the ribs 13 are formed. By cutting off, both ends of the heat collecting tube 12 protrude outward from the plate-like fins 11.

  In addition, as shown in FIG. 6, the uneven | corrugated | grooved part 12a along the circumferential direction is formed in the internal peripheral surface of the heat collecting tube 12. As shown in FIG. Thus, by forming the uneven part 12a along the circumferential direction on the inner peripheral surface of the heat collecting tube 12, the contact area between the heat medium flowing in the heat collecting tube 12 and the heat collecting tube 12 is increased, thereby improving the heat transfer efficiency. Can do.

  In addition, the standing piece 11a which protrudes toward the non-joining side is provided in the both-sides edge along the longitudinal direction of the plate-shaped fin 11. FIG. In this case, the thickness of the plate-like fin 11 is 0.8 to 2.0 mm. The reason is that if it is thinner than 0.8 mm, extrusion molding becomes difficult, and if it is thicker than 2.0 mm, the workability is lowered and the bending rigidity may be larger than that of the solar cell module 2. .

  The bending rigidity of the plate-like fins 11 of the heat collecting panel 10 formed as described above is set equal to or lower than that of the solar cell module 2.

  If the bending rigidity of the plate-like fins 11 is designed to be low, the bending process of the heat collecting panel 10 described later can be easily performed. Further, when the plate-like fins 11 are bonded to the solar cell module 2, the bent ends are pressed, and the pressing force is applied to the solar cell module 2 at that time. If the bending rigidity of the plate-like fin 11 is designed to be equal to or lower than that of the solar cell module 2, both ends of the plate-like fin 11 are pressed with a small force that does not cause deformation of the solar cell module 2. It becomes possible to join the plate-shaped fin 11 and the solar cell module 2.

  In addition, by designing the bending rigidity of the plate-like fins 11 to be small, the curvature of the plate-like fins 11 during bending of the heat collecting panel 10 is further increased, and the degree of adhesion between the plate-like fins 11 and the solar cell module 2 is increased. It becomes possible to increase.

  Further, between the solar cell module 2 and the plate-like fins 11, a sheet-like contact member 20 made of a highly heat conductive material is interposed. In this case, for the contact member 20, for example, ethylene / propylene / diene / methylene rubber (EPDM), chloroprene rubber, aluminum foil, or the like can be used. In addition, when EPDM is used for the contact member 20, an insulating effect can be enhanced between the solar cell module 2 and the plate-like fins 11 of the heat collection panel 10.

  In this case, as shown in FIG. 6, an adhesive layer 21 is formed on the surface of the contact member 20, and the connection between the contact member 20, the solar cell module 2, and the plate-like fins 11 is strengthened. . In this case, the heat collecting panel 10 can be easily replaced by forming the adhesive with a peelable soft adhesive. In addition, although the case where the adhesive layer 21 was formed on the surface of the adhesion member 20 was described here, the solar cell module 2 and the heat collection panel 10 may be joined with the adhesion member 20 having no adhesive. Good. In this way, by joining the solar cell module 2 and the heat collection panel 10 with the adhesive member 20 having no adhesive, the heat collection panel 10 can be easily replaced.

  On the other hand, both end portions of the heat collecting tube 12 in the longitudinal direction are connected to the header tube 3. In this case, the header pipe 3 is formed by closing a lid member 3b made of aluminum alloy, for example, by brazing or the like, at both ends of a square tube body 3a formed of an extruded shape made of aluminum alloy. The header tube 3 and the heat collecting tube 12 are fixed by welding or the like by inserting the end portion of the heat collecting tube 12 into a through hole (not shown) provided in one side wall of the header tube 3 formed in this way. Yes.

  One of the pair of header tubes 3 to which the heat collecting tubes 12 of the plurality of heat collecting panels 10 are connected as described above is provided with the heat medium inlet 4, and the other is the heat medium outlet. 5 is provided.

  In addition, the exposed surfaces of the plate-like fins 11 and the heat collecting tubes 12 of the heat collecting panel 10 juxtaposed to the solar cell module 2 are covered with a heat insulating material 30. In this case, the heat insulating material 30 is formed of, for example, a rectangular plate member made of polyurethane foam, and the heat collecting tube 12 and the rib 13 of the heat collecting panel 10 can be accommodated on the inner surface of the heat insulating material 30. A concave groove 31 and a rectangular concave portion 32 that can accommodate the terminal box 2a are formed (see FIG. 8).

  By covering the exposed surfaces of the plate fins 11 and the heat collecting tubes 12 with the heat insulating material by the heat insulating material 30 formed as described above, the solar thermal energy obtained through the solar cell module 2 is dissipated from the heat collecting tube 12. Can be prevented, and heat collection efficiency can be improved.

  Note that reinforcing angle members 40 for reinforcing the heat insulating material 30 are disposed at two locations outside the heat insulating material 30.

  In order to join the heat collecting panel 10 formed as described above to the solar cell module 2, the following procedure is performed.

  First, before attaching the heat collection panel 10 to the solar cell module 2, the plate-like fins 11, the ribs 13, and the heat collection tubes 12 constituting the heat collection panel 10 are joined to each other in the longitudinal direction of the heat collection tubes 12, that is, solar cells. Bending in a direction away from the module side (bending process). In this case, as a method of bending the heat collecting panel 10, for example, there are methods such as a roll bender or four-point bending.

  The roll bender is a method in which three rolls are arranged in a triangular shape, and the rolls are continuously bent by rotating and rolling the heat collection panel 10 passing between the rolls. On the other hand, the four-point bending method is a method in which four fulcrums are first provided and pressed on the front and back of the plate-like fin 11 and both ends in the length direction are bent toward the heat collecting tube to bend.

  In order to join the heat collecting panel 10 bent as described above to the solar cell module 2, as shown in FIG. 9A, the adhesion member 20 is interposed between the solar cell module 2 and the heat collecting panel 10. As shown in FIG. 9B, the heat collecting panel 10 is pressed against the back surface of the solar cell module 2 via the adhesion member 20 (bonding step). Then, first, the central protrusion in the longitudinal direction of the plate-like fins 11 of the heat collecting panel 10 comes into contact with the back surface of the solar cell module 2 via the contact member 20, and the plate-like fins 11 are pressed by pressing the heat collecting panel 10. Gradually abutting against the back surface of the solar cell module 2 along the end in the longitudinal direction, the air existing between the two is extracted to the outside, and the gap between them is eliminated. In addition, when using aluminum foil for the adhesion | attachment member 20, in order to eliminate a clearance gap reliably, it is better to use what formed innumerable wrinkles on aluminum foil.

  As described above, by joining the solar cell module 2 and the plate-like fins 11 of the heat collection panel 10 with the adhesion member 20 interposed therebetween, the adhesion between the solar cell module 2 and the heat collection panel 10 is improved. In addition, the solar thermal energy obtained by receiving light by the solar cell module 2 can be efficiently transferred to the heat collecting tube 12 of the heat collecting panel 10, and the heat exchange efficiency can be improved.

  In addition, by setting the bending rigidity of the plate-like fins 11 to be lower than that of the solar cell module 2, deformation of the solar cell module 2 due to the joining of the heat collecting panel 10 can be suppressed.

  The composite panel 1 configured as described above is used by being attached in an inclined manner by a pedestal (not shown) installed on the roof of a building, for example. For example, as shown in FIG. 1, a supply pump P and an open / close valve Va are provided in a heat medium inflow pipe 6 having one end connected to the inlet 4 of the header pipe 3 on the inclined lower side, and the other end is connected to the heat medium. Connect to source 7. In addition, an on-off valve Vb is provided in the heat medium outlet pipe 8 having one end connected to the outlet part 5 of the header pipe 3 on the inclined upper side, and the other end is connected to the temperature control part 9 so that the hot water using solar heat is provided. It can be used as an oven or air conditioning system. In this case, the supply pump P and the on-off valves Va and Vb may be electrically connected to a controller (not shown) to control supply / stop of the heat medium and supply amount based on a signal from the controller.

  In this case, water can generally be used as the heat medium. As a heat medium other than water, for example, an antifreeze such as ethylene glycol, propylene glycol, or ethyl alcohol, an aqueous lithium bromide solution that absorbs water vapor in a vacuum, or the like can be used.

  Further, when an “inhibitor” is mixed as an anticorrosive agent, the anticorrosion of a metal such as aluminum can be suppressed. In this case, inorganic inhibitors include various chromates, nitrites, silicates, polyphosphates, and the like. Organic inhibitors used for organic materials include carboxylic acids such as oleic acid, timer acid, naphthenic acid, carboxylic acid metal soaps (lanolin Ca, naphthenic acid Zn, oxidized wax Ca, Ba acid, etc.), sulfonates ( Na, Ca, Ba sulfonate), aminic acid, and esters (such as glycerin esters of higher fatty acids, sorbitan monoisostearate, sorbitan monooleate). All of these inhibitors have high adsorptive power, and prevent the occurrence of rust by forming multiple adsorption films.

  According to the composite panel 1 of the above-described embodiment, a plurality of heat collecting panels 10 in which the plate-like fins 11 and the heat collecting tubes 12 are integrally formed are joined to the back surface of the solar cell module 2 to form a solar cell. Since a plurality of heat collecting panels can be juxtaposed on the back side of the module 2, the number of components can be reduced, and the heat exchange efficiency with high design flexibility of the heat collecting tube 12 can be improved.

  In addition, the solar cell module 2 and the heat collection panel 10 are joined to each other by interposing a sheet-like adhesion member 20 made of a highly heat conductive material between the solar cell module 2 and the plate-like fins 11 of the heat collection panel 10. The adhesiveness with the panel 10 can be improved, and the solar thermal energy obtained by the solar cell module 2 receiving light can be efficiently transferred to the heat collecting tube 12.

  Further, by covering the exposed surfaces of the plate-like fins 11 and the heat collecting tubes 12 with the heat insulating material 30, it is possible to further prevent the solar thermal energy obtained through the solar cell module 2 from being radiated from the heat collecting tubes 12. it can.

  Furthermore, by forming the plate-like fins 11 and the heat collecting tubes 12 with an aluminum extruded shape, a heat collecting panel with high thermal conductivity and high dimensional accuracy can be easily produced. In addition, since the aluminum member is also excellent in recyclability, the material can be reused even after aging, and resources can be effectively used.

  In addition, although the said embodiment demonstrated the case where the uneven | corrugated | grooved part 12a along a circumferential direction was formed in the internal peripheral surface of the heat collecting tube 12, the material which has heat conductivity in the site | part which the internal peripheral surface of the heat collecting tube 12 opposes. For example, the auxiliary heat transfer plate 14 made of an aluminum thin plate may be connected. As a connection form of the auxiliary heat transfer plate 14, for example, as shown in FIG. 10 and FIG. 11, a pair of concave grooves 12b are formed in the longitudinally opposite portions of the inner peripheral surface of the heat collecting tube 12, and both concave grooves 12b are formed. The auxiliary heat transfer plate 14 may be inserted into the inside. In this case, the auxiliary heat transfer plate 14 may be inserted over the entire length of the heat collecting tube 12, or a predetermined length may be inserted from both ends of the heat collecting tube 12. Further, the heat collecting tube 12 and the auxiliary heat transfer plate 14 may be integrally formed by extrusion instead of the insertion of the auxiliary heat transfer plate 14.

  By comprising in this way, the heat transfer efficiency can be improved by increasing the contact area between the heat medium flowing in the heat collection tube 12, the heat collection tube 12, and the auxiliary heat transfer plate.

  The heat collecting panel 10 in the present invention may be a circular heat collecting tube 12A as shown in FIG. 12 (a) instead of the heat collecting tube 12, or as shown in FIG. 12 (b), for example. In addition, a pair of concave grooves 12b are formed in the longitudinally opposite portions of the inner peripheral surface of the heat collecting tube 12A, and an auxiliary heat transfer plate 14 made of a material having thermal conductivity, for example, an aluminum thin plate, is formed in both concave grooves 12b. You may insert the full length of the heat collecting tube 12A, or predetermined length of both ends. Note that the heat collection tube 12 and the auxiliary heat transfer plate 14 may be integrally formed by extrusion instead of fitting.

  In addition, although the said embodiment demonstrated the case where the contact | adherence member 20 was interposed between the solar cell module 2 and the plate-shaped fin 11 of the heat collecting panel 10, a solar cell module was not interposed. 2 and the plate-like fins 11 of the heat collecting panel 10 may be directly joined. In this case, the solar cell module 2 and the plate-like fins 11 of the heat collecting panel 10 are bonded via an adhesive or a pressure sensitive adhesive, or the solar cell module 2 and the heat collecting panel are not used without using the adhesive or pressure sensitive adhesive. Ten plate-like fins 11 may be joined.

  As a method of joining the solar cell module 2 and the plate-like fins 11 of the heat collection panel 10 without using an adhesive or a pressure-sensitive adhesive, for example, a plate shape of the solar cell module 2 and the heat collection panel 10 using an adhesive sheet. There is a method of joining the fins 11 or fixing and joining the solar cell module 2 and the plate-like fins 11 of the heat collecting panel 10 using a frame material.
