Photovoltaic module and diode heat dissipation method

The invention relates to a photovoltaic module. The photovoltaic module comprises a diode and a heat dissipation device, the heat dissipation device is attached to one side of the cathode layer of the diode; a channel with a preset pattern is arranged in the heat dissipation device, a liquid medium is arranged in the channel, and the liquid medium is used for taking away heat generated by the diode during flowing. According to the embodiment of the invention, the heat generated by the diode can be dissipated when the liquid medium in the heat dissipation device circularly flows through the arrangement of the heat dissipation device, so that the temperature of the diode is reduced, the reliable work of the diode is ensured, and the service life of the diode is prolonged. 本公开是关于一种光伏模块，包括二极管和散热器件；所述散热器件贴合到所述二极管的阴极层一侧；所述散热器件内设置有预设图案的通道，所述通道内设置有液体媒介，所述液体媒介用于在流动时带走所述二极管产生的热量。本实施例通过设置散热器件，可以使散热器件内的液体媒介循环流动时将二极管所产生的热量散发，从而降低二极管的温度，保证二极管可靠工作，有利于延长二极管的寿命。
