Low-power concentrating photovoltaic strip-shaped stepped radiating-fin radiator

Abstract

The invention relates to a concentrating photovoltaic radiating part, in particular to a low-power concentrating photovoltaic strip-shaped stepped radiating-fin radiator, and belongs to the technical field of solar generation. The low-power concentrating photovoltaic strip-shaped stepped radiating-fin radiator comprises a stepped radiating fin segment array, radiating ventilation grooves, a radiator bottom plate, a round fixed column and a concentrating photovoltaic photoelectric conversion receiver mounting area, wherein the stepped radiating fin segment array is arranged on one face of the radiator bottom plate, and the round fixed column and the concentrating photovoltaic photoelectric conversion receiver mounting area are arranged on the other face of the radiator bottom plate; the radiating ventilation grooves are gaps among stepped radiating fin segments in the stepped radiating fin segment array. The radiator can perform internal radiating by utilizing natural wind in all different directions; the radiator is light in weight and extremely high in mounting efficiency, and the mounting cost is greatly improved; the radiator is quite convenient to maintain and replace subsequently by being directly screwed to a concentrating photovoltaic module base.

Description

technical field [0001] The invention relates to a concentrating photovoltaic heat dissipation component, in particular to a low-magnification concentrating photovoltaic strip-shaped ladder-shaped fin radiator, which belongs to the technical field of solar power generation. 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 low-magnification lens, the operating temperature on the surface of the concentrating photovoltaic cell and the receiver is too high, which affects the conversion efficiency of the concentrating photovoltaic cell chip. In order to ensure that the concentrating photovoltaic cell and the receiver The receiver can work stably in the normal temperature range. Generally, the concentrated ph...

Problems solved by technology

Due to the relatively high light energy collected by the low-magnification lens, the operating temperature on the surface of the concentrating photovoltaic cell and the receiver is too high, which affects the conversion efficiency of the concentrating photovoltaic cell chip. In order to ensure that the concentrating 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 outside air, and the heat generated by the concentrated sunlight is directly It is radiated into the external air by the radiator, but the existing concentrated 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 concentrated 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
