Abstract

The present invention proposes a photovoltaic module junction box, which includes: a box body, which defines an accommodation space; The bus bars of the panel are electrically connected in the accommodating space; the diodes are electrically connected between the second ends of the adjacent contact rails, wherein the diodes are located outside the box body. The invention also relates to a photovoltaic module having the junction box. By using the technical solution of the present invention, the diode with large heat generation is placed outside the junction box, thereby improving the heat dissipation of the diode and greatly improving the heat dissipation performance of the junction box.

Description

technical field [0001] The invention relates to a junction box of a photovoltaic module and a photovoltaic module with the junction box of the photovoltaic module. Background technique [0002] In the prior art, for the photovoltaic module, the diode is placed in the box body of the junction box of the photovoltaic module (hereinafter referred to as the junction box). However, the heat emitted by the diode is very large when it is working. For example, the bypass diode generally uses a silicon rectifier diode or Schottky diode packaged in a cylindrical shape, but due to the characteristics of the diode package, the current it can carry is about 10A and the heat is relatively large during operation. This generally requires the junction box to be relatively large in order to provide sufficient heat dissipation. In addition, if the heat dissipation performance of the junction box is not good, it will directly lead to the performance degradation of the junction box, and even c...
