Problems solved by technology

On the one hand, experienced assembly increases the production cost. On the other hand, when the operator is not skilled, it is difficult to control the torque during assembly, which will easily lead to the breakage of the ceramic substrate or thermoelectric material grains in the thermoelectric device, reducing the quality of the thermoelectric component. Thermoelectric performance and production efficiency

Abstract

The invention relates to the technical field of thermoelectric assemblies, and provides a thermoelectric device and cooling fin integrated thermoelectric assembly, which comprises a first ceramic substrate, a second ceramic substrate and thermoelectric material crystal grains, a first flow deflector is welded on the first ceramic substrate, a second flow deflector is welded on the second ceramic substrate, one end of the thermoelectric material crystal grain is welded on the first flow deflector, and the other end of the thermoelectric material crystal grain is welded on the second flow deflector; at least one of the first ceramic substrate and the second ceramic substrate is a ceramic substrate with fins, and the ceramic substrate with the fins comprises a ceramic base and radiating fins which are integrally formed. The conversion efficiency of the thermoelectric assembly can be improved, the production cost of the thermoelectric assembly is reduced, and the production efficiency of the thermoelectric assembly is improved.

Description

technical field [0001] The invention relates to the technical field of thermoelectric components, in particular to a thermoelectric component in which a thermoelectric device and a cooling fin are integrated. Background technique [0002] At present, in the thermoelectric device industry, traditional thermoelectric components are component structures in which thermoelectric devices and heat sinks are independently manufactured and then assembled together. Such as figure 1 As shown, the traditional thermoelectric device is formed by welding thermoelectric material grains 3 and two thin ceramic substrates, that is, the first ceramic substrate 1 and the second ceramic substrate 2, and the heat sink 9 is made of aluminum or copper material. become. [0003] When used, thermoelectric devices must be bonded to metal heat sinks with thermal grease, thermal pads, phase change materials, graphite sheets, and fasteners. This creates an interface between the thermoelectric device an...
