Problems solved by technology

[0003] Affected by factors such as design, manufacturing, and environment, thermoelectric power generation still has problems such as short service life and low reliability of thermoelectric components, especially for thermoelectric generators that work under high temperature conditions.
When the temperature of the hot and cold ends of the thermoelectric device changes, due to the thermal expansion coefficient mismatch between the thermoelectric material part and the current-conducting electrode and the substrate, a large thermal stress will be generated at the joint, which will deform the substrate or cause the thermoelectric element to break. , reducing the service life and reliability of thermoelectric components

Abstract

The embodiment of the invention discloses a thermoelectric generator, which relates to the technical field of thermoelectric generation. The thermoelectric generator comprises a first base, a second base and a thermoelectric material, wherein the first base is contacted with one thermal end; the second base is contacted with one cold end; and the thermoelectric material is arranged between the first base and the second base, and has a structure with reduced thermal stress. Through the above scheme, the thermal stress of the thermoelectric material can be reduced, and the service life and the reliability of a thermoelectric generation module are improved.

Description

technical field [0001] The invention relates to the field of temperature difference power generation, in particular to a specific structure of thermoelectric material components in a thermoelectric generator. Background technique [0002] A thermoelectric generator is a generator that uses the Seebeck effect to convert thermal energy into electrical energy. The thermoelectric generator is a solid-state device with no rotating parts, small size, long life, no noise during operation, and no maintenance. Thermoelectric power generation technology is mainly used in high-tech fields such as aerospace, military, and deep-sea exploration. Its simplicity and stability can well solve the problems of power supply device amplitude, inconvenient maintenance and replacement, and noise pollution. More than 40% of the energy produced by automobile fuel is taken away by exhaust gas. If each vehicle can use the temperature difference power generation technology and make reasonable use of it...
