Combined heat-dissipation electricity-resistant aluminum alloy solar frame

According to the scheme, the combined heat dissipation electricity-resistant aluminum alloy solar frame comprises four frame pieces, the two ends of each frame piece in the length direction are each provided with a sliding groove, a sliding block is arranged in each sliding groove, and each sliding block is provided with a threaded hole; the four connecting pieces are arranged between every two adjacent frame pieces, and the frame pieces and the connecting pieces are fixed through cooperation of stainless steel screws and the threaded holes of the sliding blocks; magnet sheets are arranged at the two ends of the covering part respectively, the covering part is matched with the stainless steel screws to cover the joint of the connecting part and the two adjacent frame parts, and the covering part at least can cover the sliding grooves; the heat conduction pads are respectively arranged inside and on the outer wall of each frame piece; the heat dissipation blocks are sequentially spliced outside the covering pa
