Technical Field
The invention belongs to the technical field of solar power generation, and particularly relates to a solar cell backboard cooling device.
Background
In a solar power generation system, solar cells absorb solar energy to generate power, and the temperature of the cells themselves rises. The power generation efficiency of the solar cell is reduced along with the temperature rise, so that the effective temperature reduction of the solar cell can obviously improve the power generation efficiency of the solar cell. At present, a common cooling method is to fix metal ribs on a solar cell back plate, and the metal ribs absorb heat of the solar cell back plate through heat conduction so as to reduce the temperature of the solar cell. However, after the metal ribs absorb heat, the heat is not easy to dissipate in the frame of the power generation system component, so that the cooling effect is not good, and the power generation efficiency of the solar cell is further influenced. The cooler which uses the phase-change material to cool down is occasionally seen in other fields, but because the phase-change material has poor heat conductivity, if the phase-change material is directly used for cooling down on the solar cell backboard, the heat of the backboard is hard to conduct away quickly, the cooling effect of the solar cell is influenced, and therefore, the cooler which directly uses the phase-change material for cooling down in the field of solar cell power generation is not suitable.
