Abstract

The invention relates to a producing method for antimonide cobalt-based heat devices, which is characterized in that the invention first uses SPS method to produce a single pair or a plurality of pairs of hot electricity block turning 90 degrees of P-N and effectively prevents a plurality of elements of thermoelectric semiconductor from diffusing by a plasma sprayed disusing barrier thin layer on the hot electricity block, and the use of disusing barrier thin layer changes the connection between thermoelectric semiconductor and metal electrode into connection between metals to more facilitate metal electrode unit, and the application of a near-hypoeutectic Ag-Cu solder sheet not only can satisfy temperature use ranging from 500 DEG C to 600 DEG C system of high temperature end antimonide cobalt-based heat device, but also can provide a good welding material for producing other hyperthermia electric material devices, and the electrode material applies an electrode material having a similar thermal expansion coefficient with antimonide cobalt to realize heat match on a greatest degree and reduce thermal stress produced by thermal mismatch.

Description

technical field

[0001] The present invention relates to cobalt antimonide CoSb 3 The preparation method of base thermoelectric device, more precisely the present invention relates to the connection method of cobalt antimonide thermoelectric material and electrode, belongs to CoSb 3 The technical field of preparation of base thermoelectric devices. Background technique

[0002] Thermoelectric material is a functional material that directly converts thermal energy and electrical energy into each other. It uses its own Seebeck effect to directly convert thermal energy into electrical energy. With the increasing severity of global environmental pollution and energy crisis, the design and preparation of thermoelectric devices has received more and more attention from all over the world. Refrigeration and power generation devices made of thermoelectric materials are small in size, light in weight, without any mechanical transmission parts, noiseless in operation, and long in ser...
