Abstract
The utility model relates to a modified photovoltaic module junction box. A traditional photovoltaic module junction box mainly adopts axial diodes and dissipates heat mainly by aid of air medium on connections. The modified photovoltaic module junction box comprises a junction box and a junction box cover, wherein the junction box cover matched with the junction box in size is arranged on the surface of the junction box, a connection board is arranged inside the junction box, a positive pole and a negative pole of a solar cell are externally connected to the top end of the connection board, two connection terminals are arranged at the tail end of the connection board and respectively externally connected with a positive pole and a negative pole of an accumulator through leads, a plurality of diodes are arranged between the top end and the tail end of the connection board, and radiators are arranged on the sides of the diodes. The modified photovoltaic module junction box has the advantages that the modified junction box adopts the novel surface-mounted diodes welded together with large-area high-energy radiating copper fins, all connections are fused by means of metal butt welding, the radiation effect is doubled, and the service life of the modified photovoltaic module junction box is prolonged.
