A cooling device for improving the power generation capacity of photovoltaic cells

Abstract

The invention discloses a cooling device for improving the power generation capacity of photovoltaic cells, which is a T-shaped radiating pipe composed of a main pipe and at least one side pipe that communicate with each other; The fins are provided with brackets for placing photovoltaic cells on the side tubes. Compared with the existing solar tracker, the cooling device for improving the power generation capacity of the photovoltaic cell of the present invention has outstanding advantages including: due to the use of the heat pipe heat transfer principle in which the two phases of the cooling medium alternately change under high vacuum conditions, the The cooling device has the characteristics of quick start of the cooling process, small temperature difference between the cooling end (main pipe) and the heating end (side pipe), so that both ends have strong heat absorption and heat dissipation capabilities, and the heat on the photovoltaic cells can be dissipated efficiently and quickly, which will effectively guarantee Photovoltaic power generation components have high conversion efficiency and long service life. After testing, the cooling device can meet the use requirements of 1000 times of light concentration, which greatly improves the power generation capacity of photovoltaic cells.

technical field [0001] The invention relates to a photovoltaic power generation device, in particular to a cooling device for improving the power generation capacity of photovoltaic cells. Background technique [0002] During the normal operation of the photovoltaic power generation module, the light energy projected onto the chip (photovoltaic cell), except partly converted into electrical energy, most of the remaining energy is converted into heat energy, which must be taken away from the chip and released to the atmosphere immediately. In order to protect the normal operation of the components, otherwise, the temperature difference between the inside and outside of the chip will decrease, which will reduce the power generation efficiency, and even the high temperature will burn out the chip and cannot continue to generate electricity.

Problems solved by technology

[0002] During the normal operation of the photovoltaic power generation module, the light energy projected onto the chip (photovoltaic cell), except partly converted into electrical energy, most of the remaining energy is converted into heat energy, which must be taken away from the chip and released to the atmosphere immediately. In order to protect the normal operation of the components, otherwise, the temperature difference between the inside and outside of the chip will decrease, which will reduce the power generation efficiency, and even the high temperature will burn the chip and cannot continue to generate electricity

The existing chip cooling methods mainly include water cooling, forced ventilation cooling and natural cooling. Water cooling requires water and power consumption; forced ventilation cooling requires power consumption, and it is difficult to achieve efficient cooling; Photovoltaic power generation components need to dissipate a large amount of heat

Therefore, the efficient heat dissipation of photovoltaic cells is one of the core issues restricting the power generation capacity of existing batteries. Under the existing heat dissipation capacity, the optimal power generation components can only meet the power generation requirements of about 500 to 600 times the light concentration. Far from meeting the needs of use
