[0019] like Figure 1 As shown, the heat dissipation structure of the photovoltaic mounting frame described in the utility model includes a water-cooled heat dissipation structure and an air-cooled heat dissipation structure. The water-cooled heat dissipation structure includes a serpentine pipe 5, a water tank 6, a circulating pump 7, a cooling rod 8, a semiconductor refrigeration sheet 9, a housing 11 and a heat dissipation fan 10. The serpentine pipe 5 is arranged in the mounting frame and is located below the photovoltaic panel. The water tank 6 is arranged at the top of the mounting frame 1. The serpentine pipe 5 and the water tank 6 are connected by the circulating pump 7 and the connecting pipe to form a water-cooled circulation pipeline. The air-cooled heat dissipation structure includes an air intake fan 12 and an air outlet 13 opened along the thickness direction on both sides of the mounting frame. The air intake fan 12 is arranged on the side of the mounting frame 1 close to the support assembly 3.

The upper front of the upper side wall of the base 2 is hinged with a mounting frame 1 through a first hinge seat, and the mounting frame 1 is used to install a photovoltaic panel 4. Two symmetrically distributed second hinge seats 14 are installed on the upper rear side wall of the base 2.
