Abstract

The invention discloses a thermoelectric power generation device based on radiation cooling and a preparation method thereof, the device takes a sheet-shaped thermoelectric power generation element as a core, the cold end of the thermoelectric power generation element is attached to the lower part of a film-shaped radiation cooling element, and all-day cooling is realized by utilizing a space cold source through radiation cooling; the hot end of the temperature difference power generation element is attached to the plate-shaped temperature conduction element, the area of the temperature conduction element is large, the temperature conduction element can be arranged on any outdoor flat object, and in the day or sunny day, the temperature conduction element is used for absorbing solar radiation, heating the temperature difference power generation element and heating the surface near the temperature conduction element at the same time. In cloudy days or at night, the temperature conduction element can absorb nearby waste heat to heat the power generation sheet, so that the two sides of the thermoelectric power generation element can form a temperature difference in all weather / all seasons, and voltage is output to a load based on the Seebeck effect.

Description

technical field [0001] The invention relates to the technical field of thermoelectric power generation, in particular to a thermoelectric power generation device based on radiation cooling and a preparation method thereof. Background technique [0002] At present, the most energy used for power generation is still non-renewable energy such as petroleum, coal, and natural gas. When these raw materials are not completely burned, it will cause environmental pollution and energy waste. In recent years, although new energy solar energy, tidal energy, and wind energy have developed well and have been put into practical application, they are all limited by time and region. For example, solar energy can only be used during the day, and tidal energy can only be used in coastal areas. If you want to realize All-day power supply and power supply for various regions need to be used with power storage devices and power grids, which will increase the cost of the entire power generation sy...
