Thermoelectric power generation device

Abstract

The invention discloses a thermoelectric power generation device, comprising a furnace and two heat transfer plates, wherein the heat transfer plates comprise a heating part and a heat transfer part,two heat transfer parts abutting each other form a heating group, and further comprises a thermoelectric power generation sheet with one side abutting on a corresponding heat transfer part; a coolingelement that abuts against a side of the thermoelectric power generating sheet opposite to the heat transfer portion; Press plate; and a controller. The two platens on both sides of the heating groupare fixed by a first fastener and a second fastener, wherein the first fastener is in line contact with the through hole, and the second fastener is located on the outside of the heat transfer plate and the cooling element and is not in contact with the heat transfer plate and the cooling element. The second fastener of the present application is not in contact with the heat transfer plate and thecooling element. The first fastener can effectively reduce the heat transfer compared with the existing surface contact in the form of line contact with the through hole, and the influence on the heat transfer part and the cooling element can be reduced as much as possible, so that the heat transfer of the first fastener is not affected.

Description

technical field [0001] The invention relates to the field of power generation, in particular to thermoelectric power generation equipment. Background technique [0002] With the development of science and technology, various illuminators and portable electronic products are becoming more and more abundant, and people are more and more dependent on them. However, these illuminators and Power supplies for electronic products often render them unusable because they cannot be replenished with electrical energy. [0003] The Seebeck effect refers to the thermoelectric phenomenon in which the voltage difference between two substances is caused by the temperature difference between two different electrical conductors or semiconductors. The thermoelectric power generation sheet uses the Seebeck effect to convert heat energy into electrical energy. In order to generate electric energy in the field and other places, a biomass fuel thermoelectric generator can be designed by using thi...

Problems solved by technology

In this structural form, the fastener and the heat transfer plate are in surface contact with a large contact area, and a large amount of heat energy will be conducted to the cooling element through the fastener, which will not only waste heat energy, but also reduce the cooling efficiency of the cooling element, thereby reducing the temperature difference power generation efficiency
