If the temperature is too high, it will also affect the life of the solar cell
In view of the fact that the peak of solar radiation is around noon, and the solar cells are working at the maximum power generation, and this time coincides with the period when the sun's thermal radiation is the strongest, and the heating effect on the solar panels and the surrounding environment is extremely strong, so The high temperature environment of solar panels greatly reduces the power generation efficiency, which is not conducive to the synchronization of peak power generation and power generation, wastes solar energy resources in a limited period of time, and greatly weakens the power generation of solar cells within their service life

The invention discloses an efficient and natural cyclic back radiator for a photovoltaic battery panel. The efficient and natural cyclic back radiator comprises a box body mounted on the backside of the photovoltaic battery panel, wherein the box body is internally provided with a separation board and is divided into a heat absorbing chamber close to the backside of the photovoltaic battery panel and a heat dissipation chamber far away from the backside of the photovoltaic battery panel by the separation board; the heat of the photovoltaic battery panel is directly taken away by the box body as an air cooling radiator, or a heat conduction working medium is added in the box body, the heat of the photovoltaic battery panel is absorbed by the heat conduction working medium and is circularly transmitted to the heat dissipation chamber for heat dissipation. The efficient and natural cyclic back radiator comprises a cooling box, a detachable seal structure in the cooling box, an insulation thermal circulating structure and an external heat absorption and dissipation structure; and the temperature of a backboard of the photovoltaic battery panel can be effectively reduced through the heat absorption and dissipation and circular flow of the heat conduction working medium, so that the solar battery panel can efficiently and safely work at the temperature as low as possible and with a long service life.
Description
technical field [0001] The invention relates to a heat dissipation device for a photovoltaic battery panel, in particular to a high-efficiency natural circulation back heat dissipation device for a photovoltaic battery panel. Background technique [0002] Photovoltaic solar panel is a special device for photovoltaic power generation. After manufacture, in addition to the main power generation function, the service life requirement is more than 20 years. The ideal operating temperature of solar cells is 25 degrees Celsius, and the power of the panels decreases as the temperature increases. However, it can be used normally if the temperature does not exceed 45 degrees Celsius. If the temperature is too high, it will also affect the life of the solar cell. In view of the fact that the peak of solar radiation is around noon, and the solar cells are working at the maximum power generation, and this time coincides with the period when the sun's thermal radiation is the strongest...
