Solar photovoltaic-temperature difference automatic temperature control joint power generation unit

Abstract

The invention relates to a solar photovoltaic-temperature difference automatic temperature control joint power generation unit; and a solar photovoltaic power generation system serves as main energy, and semi-conductor temperature difference power generation serves as the important auxiliary means of battery temperature feedback and control. A semi-conductor temperature difference power generation module generates power by utilizing the temperature difference between the back side of a solar cell and the ambient temperature, and transmits the power into a control system to regulate a fan in a radiator as automatic feedback. A controller can automatically judge whether the temperature of a cooling medium of a solar panel is too high or not, and determine whether to start an additional strong radiating fan in a chimney-type cooler or not. The chimney-type cooler achieves the purpose of reducing the temperature of the cooling medium by utilizing a chimney effect, a cooling effect is in inverse proportion with the temperature, so that the roles of automatically feedback and regulation are played. According to the unit, semi-conductor temperature difference power generation and solar photovoltaic power generation technologies are effectively integrated, low-grade heat when the solar cell generates power is fully utilized and converted into radiating energy, so that a great role of improving the efficiency of the solar photovoltaic cell is played.
