Abstract

The invention discloses a micro thermoelectric module and a production method thereof. The production method includes the following steps: acquiring a thermopile with a sandwich structure, wherein the thermopile comprises a first electrode layer, a second electrode layer and a staggered P-N type thermoelectric sheet array sandwiched between the first electrode layer and the second electrode layer, and processing separating grooves on the thermopile to form multiple thermoelectric units of the array. Compared with the prior art, the micro thermoelectric module and the production method thereof have the advantages that integration of thermopile manufacture and electrode connection processing can be realized only through a precise gas cutting machine, and electrode micro-processing procedures in the prior art are omitted, so that needed equipment and process cost are reduced, requirements on worker operating proficiency are low, and convenience is brought to mass production.

Description

technical field [0001] The invention relates to the field of thermoelectricity, in particular to a miniature thermoelectric module and a manufacturing method thereof. Background technique [0002] Thermoelectric devices refer to a class of electronic components that can directly convert electric energy to thermal energy. Its core is a thermoelectric module composed of multiple groups of thermoelectric materials with different carrier types connected in series and parallel. [0003] The application of thermoelectric devices has a history of more than one hundred years. In the early days, they were mainly used to detect temperature, such as thermocouples. Later, with the development of high-performance thermoelectric materials, they were used in electronic temperature control, waste heat power generation and aerospace battery packs and other fields. In the past 20 years, the miniaturization technology of thermoelectric modules has received more and more attention because of i...
