[0020] A heat-conducting layer 9 is installed on the side of the hollow frame 1 near the photovoltaic panel 6, and a second heat-conducting pipe 10 is fixedly installed on the side of the heat-conducting layer 9. The second heat-conducting pipe 10 is built into the cavity of the central frame, and a through groove 8 is provided on the side of the second heat-conducting pipe 10. An air outlet 11 is opened on the side of the hollow frame 1, and the air outlet 11 is connected to the second heat-conducting pipe 10. A fixing groove 12 is provided on the top of the hollow frame 1. The heat-conducting layer 9 and the first heat-conducting pipe 7 are designed so that the heat-conducting layer 9 is in close contact with the photovoltaic panel 6. Through the heat transfer of the first heat-conducting pipe 7 and the second heat-conducting pipe 10, a high-temperature heat collection area will be formed in the cavity area of ​​the hollow frame 11.

[0022] The heat dissipation assembly includes a heat transfer plate 15, which is disposed on the top of the limiting frame 5. The top of the heat transfer plate 15 is in close contact with the photovoltaic panel 6. A vertical fin assembly 16 is fixedly installed on the bottom of the heat transfer plate 15, and a horizontal fin assembly 17 is fixedly installed on the bottom of the heat transfer plate 15.

[0023] A connecting base plate 18 is fixedly connected to the sides of the vertical fin group 16 and the horizontal fin group 17. The bottom of the connecting base plate 18 has a snap-fit ​​groove 19, which is inserted into the snap-fit ​​post 14.

This heat is transferred to the hollow frame that is tightly connected to it through heat conduction. On frame 1, the heat-conducting layer 9 is in close contact with the photovoltaic panel 6. Through the heat transfer via the first heat-conducting pipe 7 and the second heat-conducting pipe 10, a high-temperature heat collection area is formed in the cavity near the heat-conducting layer 9 of the hollow frame 1. The heat transfer plate 15 is in contact with the photovoltaic panel 6, and the heat is quickly dispersed to the horizontal fin group 17 and the vertical fin group 16, which will generate a lower-temperature heat dissipation area in the cavity. A temperature difference is formed between the heat dissipation area and the heat collection area. Air circulates in the ventilation hole 3, the inner cavity of the hollow frame 1 and the air outlet 11, generating convection, which greatly improves the heat dissipation efficiency of the heat dissipation fins, effectively reduces the operating temperature of the photovoltaic module, improves the power generation efficiency, and extends the service life of the module.
