Abstract

The invention discloses a cooling device for a dish-type solar concentrated photovoltaic battery panel, which belongs to the technical field of cooling of the concentrated photovoltaic battery panel. The present invention aims to solve the problem that the existing concentrating photovoltaic panel cooling technology is difficult to meet the temperature control requirements, and the heat conduction performance is poor, thereby reducing the solar power generation efficiency. The heat dissipation plate of the present invention is a hollow heat dissipation plate, and the fixed bracket is a hollow support. A heat pipe is arranged in each fixed support. The upper end of the heat pipe communicates with the heat dissipation plate. Metal foam is sintered in the cavity between the heat pipe and the fixed bracket, the metal foam is filled with solid-liquid phase change material, the upper opening of the fixed bracket is sealed with a seal, and a layer of heat pipe liquid-absorbing core is arranged on the inner wall of the heat pipe. The invention is used for the heat dissipation of dish-type solar concentrating photovoltaic panels.

Description

technical field [0001] The invention relates to a cooling device for a concentrating photovoltaic cell panel, in particular to a cooling device for a dish-type solar concentrating photovoltaic cell panel, and belongs to the technical field of concentrating photovoltaic cell panel cooling. Background technique [0002] With the reduction of the world's petrochemical energy reserves and the increasingly serious environmental pollution problems, solar energy as a clean and sustainable use has been widely used, so it can be predicted that the proportion of solar power generation in the energy structure is increasing. The highest efficiency of solar power generation can reach 31%. As the power generation process progresses, the solar power generation device will continue to release heat, causing its temperature to become higher and higher, and the increase in temperature will lead to a decrease in its power generation efficiency. Excessive temperature may even burn out the battery...
