Low power concentrating photovoltaic radiator with segment staggered-step-shaped cooling fins

Abstract

The invention belongs to the technical field of solar power generation, and relates to a concentrating photovoltaic cooling component, in particular to a low power concentrating photovoltaic radiator with segment staggered-step-shaped cooling fins. The radiator comprises a staggered-step-shaped cooling fin segment array, cooling and ventilating grooves, a radiator bottom plate, a round fixing post and a concentrating photovoltaic conversion receiver mounting zone. The staggered-step-shaped cooling fin segment array is arranged on one side of the radiator bottom plate. The round fixing post and the concentrating photovoltaic conversion receiver mounting zone are arranged on the other side of the radiator bottom plate. Gaps among staggered-step-shaped cooling fin segments in the staggered-step-shaped cooling fin segment array are the cooling and ventilating grooves. By adoption of the radiator, natural wind in different directions can be utilized for dissipating heat in the cooling fins; the radiator is low in weight and extremely high in mounting efficiency, and the mounting cost is greatly lowered; and the radiator can be very conveniently maintained and replaced in the later stage by directly screwing up the radiator to a concentrating photovoltaic assembly base.

Description

technical field [0001] The invention relates to a concentrating photovoltaic heat dissipation component, in particular to a low-magnification concentrating photovoltaic strip-segment staggered heat dissipation 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 c...

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 it is difficult to dissipate the heat in the middle of the cooling fin under the action of natural wind, that is, the cooling effect is poor, which directly affects the The normal operation of the concentrated photovoltaic receiver, in addition, the installation of the existing radiator is fixed to the bottom of the concentrated photovoltaic module by multiple screws, so that it will cost a lot of manual operation during installation, and it will be repaired or replaced in the follow-up very inconvenient
