Description

technical field [0001] The invention relates to a concentrating photovoltaic heat dissipation component, in particular to a high-power concentrating photovoltaic segment-shaped heat dissipation fin cooling module, which belongs to the technical field of solar power generation and heat dissipation. Background technique [0002] The concentrated photovoltaic photoelectric conversion receiver is the core component of the concentrated photovoltaic power generation system, which is used to directly convert the light energy gathered by the lens into electrical energy. Due to the relatively high light energy collected by the high-power lens, the operating temperature on the surface of the concentrated photovoltaic cell and the receiver is very high, which affects the conversion efficiency of the concentrated photovoltaic cell chip. In order to ensure that the concentrated photovoltaic cell and the receiver The receiver can work stably in the normal temperature range. Generally, the...

Problems solved by technology

Due to the relatively high light energy collected by the high-power lens, the operating temperature on the surface of the concentrated photovoltaic cell and the receiver is very high, which affects the conversion efficiency of the concentrated photovoltaic cell chip. In order to ensure that the concentrated photovoltaic cell and the receiver The receiver can work stably in the normal temperature range. Generally, the concentrated photovoltaic photoelectric conversion receiver is directly bonded to the radiator. The lower end of the radiator is directly exposed to the external air, and the heat generated by the concentrated sunlight is directly generated by the radiator. The radiator emits into the outside air, but the existing concentrating photovoltaic radiator is heavy, and the heat dissipation effect is poor in the case of natural wind, which directly affects the normal operation of the concentrating photovoltaic receiver. In addition, the existing radiator The installation is fixed to the bottom of the concentrating photovoltaic module by multiple screws, which will cost a lot of manual operation during installation, and it is also very inconvenient for subsequent maintenance or replacement. At the same time, the process of installing multiple radiators In the middle, it is difficult to ensure the precise alignment of the radiator
