Photovoltaic combiner box

The utility model relates to the technical field of photovoltaic equipment, in particular to a photovoltaic combiner box, which comprises a box body, two heat dissipation boxes, a box door, a convex plate, two heat dissipation assemblies and two damping assemblies, the two heat dissipation boxes are symmetrically arranged on two sides of the box body, the inside of each heat dissipation box is communicated with the inside of the box body, and the convex plate is arranged on the box door. The convex plate is arranged in the heat dissipation boxes, the two ends of the convex plate are fixedly connected with the inner walls of the two heat dissipation boxes respectively, the box door is hinged to the outer wall of the box body, the heat dissipation assembly is arranged on the convex plate, and the two damping assemblies are arranged at the bottoms of the two heat dissipation boxes respectively. The heat dissipation box has the advantages that the heat dissipation assembly and the two heat dissipation boxes are m
