Microminiature semiconductor thermoelectric generator

Abstract

The invention discloses a microminiature semiconductor thermoelectric generator which comprises a thermoelectric power generation sheet, a heat absorption block, a heat dissipation block, a USB boosting module, a heat conduction paste, a heat preservation material and a storage battery. The thermoelectric power generation device and the USB boosting module are connected through a wire and a heat shrink tube, a heat absorption block is arranged above the thermoelectric power generation device, a heat dissipation block is arranged below the thermoelectric power generation device, the USB boosting module is connected with a storage battery, and the outer surface of the heat absorption block is coated with a heat preservation material. And the USB boosting module transmits the generated current to the storage battery and supplies the current to a small-sized electric appliance. The thermoelectric generator is small in pollution, stable in voltage, convenient to operate and free of later maintenance cost.

Description

technical field [0001] The invention relates to a small generator, in particular to a miniature semiconductor thermoelectric generator. Background technique [0002] According to the special report on energy climate change in the "2015 World Energy Outlook" issued by the International Energy Agency, it is estimated that in the next five years, the proportion of renewable energy power generation will account for 26% of the global power supply, and it is expected to increase to 33% in 2030. %. However, according to the evaluation results of authoritative organization data, the total amount of residual / waste heat in the world is huge, and 72% of the primary energy consumed will be diffused or converted into the environment. More precisely, 63% of the energy will be discharged as residual / waste heat below 100C, and its main share comes from fossil fuel power equipment such as thermal power plants, ceramic firing plants, steel plants, and automobile exhaust. Therefore, regardles...
