5A to 5C are flowcharts showing a method of manufacturing a solar composite module having both power generation and heat exchange functions according to an embodiment of the present invention. Referring first to FIG. 5A, the manufacturing method of this embodiment includes the following steps. First, a stacked structure 100a is provided. The stacked structure 100a includes a front plate 110, a first adhesive layer 121a, a photoelectric conversion layer 130, a second adhesive layer 121b, a back plate 140, a third adhesive layer 121c, and a heat exchange layer. 150, a fourth adhesive layer 121d and a thermal conductive sheet 160. The first adhesive layer 121a, the second adhesive layer 121b, the third adhesive layer 121c, and the fourth adhesive layer 121d are, for example, hot melt adhesive films. In this step, the first adhesive layer 121a, the second adhesive layer 121b, the third adhesive layer 121c, and the fourth adhesive layer 121d are not bonded to the film layer connected thereto. In addition, the detailed structure of the front plate 110, the photoelectric conversion layer 130, the back plate 140, the heat exchange layer 150, and the heat conductive sheet 160 can be referred to the above, and will not be repeated herein.

Next, layering the stack structure 100a to make the An adhesive layer 121a, a second adhesive layer 121b, a third adhesive layer 121c, and a fourth adhesive layer 121d are bonded to the film layer connected thereto. The steps of performing the lamination process are as shown in FIGS. 5B to 5C. It should be noted that, since the heat transfer tube 152 of the heat exchange layer 150 protrudes from the heat conducting plate 151 (as shown in FIG. 3B), in order to apply the average force to the stacked structure 100a in the layer pressing process, in the present embodiment, The laminating process may further include providing a pressing plate 250 (as shown in FIGS. 6A and 6B) and covering the thermal plate 160 of the stacked structure 100a with the heat transfer tube 152 of the heat exchange layer 150. The pressure plate 250 has a groove 251 corresponding to the shape of the heat pipe 152, and the heat pipe 152 is received in the groove 251, and the bottom of the groove 251 is in contact with the heat pipe 152, for example, so that the average pressure can be applied during the layer pressing process. Forced on the stack structure 100a.

The steps of the layering process will be described in detail below. First, as shown in FIG. 5B, the stacked structure 100a covered with the press plate 250 is placed in the laminating machine 200. In another embodiment, the stack structure 100a may be placed first after the laminator 200, and then the platen 250 is covered. The laminating machine 200 includes a base 210, an upper cover 220 and a film 230. The upper cover 220 is disposed on the base 210 and forms a closed chamber 240 with the base 210. The film 230 is located in the sealed chamber 240 and separates the sealed chamber 240 into a film. The first space 241 and the second space 242 on both sides of the 230, wherein the first space 241 is located between the film 230 and the base 210, the stack structure 100a is disposed in the first space 241, and the front plate 110 of the stack structure 100a faces the base 210 . After the stacked structure 100a is placed, the first space 241 and the second space 242 are subjected to a vacuuming process, and the baking process is simultaneously performed. The base 210 of the present embodiment is, for example, a heating plate, and the stack structure 100a is heated by the base 210 during the baking process. In the present embodiment, the evacuation process, for example, causes the pressure of the first space 241 and the second space 242 to be lower than 133 Pa (Pa), for example, between 50 and 100 Pa.

Next, as shown in FIG. 5C, after the first space 241 and the second space 242 are evacuated to a predetermined pressure, the second space 242 is vacuumed to fill the second space 242 with gas. In this embodiment, the film 230 is, for example, a film having ductility. When the second space 242 is vacuumed, the air pressure pushes the film 230 down to the stacked structure 100a to closely bond the stacked structure 100a. Moreover, since the first adhesive layer 121a, the second adhesive layer 121b, the third adhesive layer 121c, and the fourth adhesive layer 121d are melted into a liquid state by the simultaneous baking process, when the film 230 is pressed against the stacked structure 100a, The bubbles in the first adhesive layer 121a, the second adhesive layer 121b, the third adhesive layer 121c, and the fourth adhesive layer 121d may be excluded, so that the other film layers 110, 130, 140, 150, 160 of the stacked structure 100a are more closely stacked. When the first adhesive layer 121a, the second adhesive layer 121b, the third adhesive layer 121c, and the fourth adhesive layer 121d which are melted into a liquid state are solidified, the first adhesive layer 120a for adhering the bonded film layer as shown in FIG. 1 is formed. The second adhesive layer 120b, the third adhesive layer 120c, and the fourth adhesive layer 120d, and the stacked structure 100a, which is not bonded to each other, also becomes a stacked structure 100 in which the respective film layers are bonded as shown in FIG.

Since the manufacturing method of the present embodiment produces the stacked structure 100 including the photoelectric conversion layer 130 and the heat exchange layer 150 in the same layer press process, the process time can be shortened to improve the production efficiency. In addition, since the baking process is performed in the lamination process, the bubbles in the first adhesive layer 121a, the second adhesive layer 121b, the third adhesive layer 121c, and the fourth adhesive layer 121d can be eliminated, so that the stacked structure 100 after the fabrication is completed. The layers of the layers can be more closely stacked to provide better heat transfer efficiency, thereby increasing the heat exchange efficiency of the heat exchange layer 150.

In the manufacturing method of the embodiment, after the layering process is completed, the cover plate 170 (shown in FIG. 1) is further provided to cover the heat conducting sheet 160 and combined with the stacked structure 100. In addition, the manufacturing method of the embodiment can be further included. The combined cover plate 170 and the stacked structure 100 are fixed in the casing 180 (as shown in FIG. 4 ) and cover the transparent cover 190 . The case 180 has an opening 181, and the front plate 110 of the stack structure 100 faces the opening 181, the transparent cover 190 covers the opening 181, and a gap 191 is formed between the transparent cover 190 and the front plate 110.

In summary, in the manufacturing method of the solar composite module having the power generation and heat exchange function of the present invention, since the stack structure including the photoelectric conversion layer and the heat exchange layer can be manufactured in the same layer pressing process, the shortening can be shortened Process time to improve production efficiency, but also to make the bonding between the layers more tight, to increase the heat transfer efficiency, thereby improving the heat exchange efficiency of the heat exchange layer. In addition, the solar composite module of the present invention having both power generation and heat exchange can improve the heat exchange efficiency of the heat exchange layer because the number of layers is small and the heat conduction path to the heat exchange layer is short.

While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention.
