The invention discloses a photovoltaic temperature difference combined power generation device based on a micro heat pipe plate and W-shaped fins, and the device comprises the micro heat pipe plate which is internally provided with a plurality of groups of micro channels. The outer wall surfaces of the upper and lower sides of the micro heat pipe plate are respectively a thermoelectric power generation unit hot end and a thermoelectric power generation unit cold end. The hot end and the cold end of the thermoelectric power generation unit are respectively adhered to the photovoltaic cell paneland the heat dissipation unit. The inner wall surfaces of the upper side and the lower side of the micro heat pipe plate are connected through a temperature difference power generation unit. The photovoltaic cell panel and the temperature difference power generation unit are respectively connected with the double-input DC-DC converter to collect and store electric energy generated by photovoltaictemperature difference. Harmful heat generated in the power generation process of the solar cell panel can be efficiently utilized, and photovoltaic temperature difference combined power generation is achieved.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and specifically relates to a photovoltaic temperature difference combined power generation device based on micro heat pipe plates and W-shaped fins Background technique [0002] Solar photovoltaic power generation technology is a direct power generation method that uses photovoltaic cells to absorb solar radiant energy and convert it into electrical energy. Due to its simple power generation process, no fuel consumption, no noise and pollution, photovoltaic power generation technology has now been obtained. Wide range of applications. However, only 10%-20% of the solar radiation energy absorbed by solar cells can be converted into electrical energy. After the battery receives solar radiation for a long time, most of the remaining unused energy will continue to accumulate in the form of heat, making its The photoelectric conversion efficiency decreases due to the increasing temper...

AI Technical Summary

Problems solved by technology

If this temperature is used as the heat source of the thermoelectric battery, the temperature difference will be too small, resulting in unsatisfactory power generation efficiency of the thermoelectric battery, and at the same time, the output quality and service life of electric energy will be correspondingly reduced

[0004] It can be seen from the current situation that there is no device with a high comprehensive performance index for solar photovoltaic thermoelectric power generation, so it is particularly important to further study and improve related technologies
