Solar energy and wind energy multi-energy complementary micro self-energy supply device based on MTEG and TENG

Abstract

The invention provides a solar energy and wind energy multi-energy complementary micro self-energy supply device based on an MTEG and a TENG. The MTEG structure on the top and the TENG structure at the bottom are coupled. The micro self-energy supply device is characterized in that the MTEG structure on the top comprises a micro thermoelectric power generation device and a phase change heat storage device arranged at the upper part of the micro thermoelectric power generation device, and a top vacuum cavity and a bottom vacuum cavity are arranged at two ends of a thermocouple composed of a P-type micro thermoelectric arm and an N-type micro thermoelectric arm respectively; the thin film flapper type TENG structure at the bottom is of a transversely arranged hollow columnar structure, a flapper thin film is connected with a middle thin copper sheet so that the thin film flapper type TENG structure serves as a dielectric thin film of a frictional nanometer power generation structure to generate voltage, and the other end of the middle thin copper sheet is fixedly connected with a conducting vertical frame as a circuit load fixed between metal electrodes. The vacuum cavity can effectively avoid heat loss caused by ambient air and the upper part of a substrate, and the temperature difference between nodes at cold and hot ends is improved; and simultaneously, the flapper thin film is accelerated to swing through flowing air to improve the power generation efficiency, so that the device is simple in structure and high in practicability.
