Production Method of electronic thermoelectric cooler

Abstract

The invention belongs to the technical field of refrigeration product production technology, and especially relates to a production method of an electronic thermoelectric cooler. The production methodof the electronic thermoelectric cooler comprises the following steps: S100: providing an aluminum substrate and manufacturing an alumina insulating layer on the surface of the aluminum substrate; S200: manufacturing a line layer on the alumina insulating layer; and S300: welding a plurality of refrigeration crystals on the line layer. Firstly, the alumina insulating layer is manufactured on thesurface of the aluminum substrate; then, the line lay is manufactured on the alumina insulating lay; and finally, the several refrigeration crystals are welded on the line layer. Due to the arrangement of the alumina insulating layer, the heat conduction effect can be achieved through the alumina insulating layer; and since there is almost no gap between the alumina insulating layer and the aluminum substrate and the alumina insulating layer has a higher thermal conductivity than a traditional insulating adhesive, the thermal conduction property of the aluminum substrate can be greatly improved, and the refrigeration efficiency and power density of the whole electronic thermoelectric cooler can be further improved.

Description

technical field [0001] The invention belongs to the technical field of production technology of refrigeration products, and in particular relates to a production method of an electronic refrigeration sheet. Background technique [0002] Most of the current refrigeration equipment needs to use fluoride as a refrigerant. The harm of fluoride to the atmospheric environment has long been recognized. Refrigeration equipment has penetrated into people's life and work, as well as production and scientific research. With the development of electronic refrigeration technology, it can gradually replace the refrigeration equipment with fluoride. [0003] At present, there are a large number of electronic refrigeration products on the market, but due to the limitations of electronic refrigeration devices, no mainstream products have yet been formed. In the production of electronic refrigeration devices, insulating materials with good thermal conductivity are required. Existing mater...
