Embodiment Construction

[0017] System solar photovoltaic-temperature difference self-feedback combined power generation device such as figure 1 , 2 The principle and structural block diagram shown include solar photovoltaic power generation system, thermoelectric power generation system, cooling system, power control system and temperature control system. The heat generated during the power generation of the photovoltaic power generation system is used as the energy source. When the cooling water passes through the back channel, the heat is taken away to the chimney radiator and dissipated. The temperature difference module 2 is evenly placed at a suitable position between the back of the photovoltaic cell and the water cooling head, and part of the thermal energy is converted into electrical energy. The power generated by the two sets of temperature difference modules 2 is taken out and supplied to the strong exhaust fan 11 after being boosted and stabilized by the temperature controller 20 to enhance...

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.

Description

Technical field [0001] The invention relates to a solar photovoltaic device, in particular to a solar photovoltaic-temperature difference automatic temperature control combined power generation device. Background technique [0002] With the consumption of non-renewable energy such as oil, coal, natural gas and the exhaustion of resources, people hope to solve the increasingly serious energy crisis caused by the exhaustion of non-renewable energy resources through the development and utilization of new energy such as solar energy. Solar photovoltaic power generation is a technology that can directly convert solar energy into electrical energy. During the process of power generation, it will not have a large adverse effect on the surrounding environment, so it is more and more favored by people. The photovoltaic cells currently used in commercialization are mainly silicon-based solar photovoltaic cells, and their output characteristics change significantly with the increase of temp...
