Embodiment 1

[0061] This embodiment 1 is to prepare CoSb with coating structure 3 Base-filled skutterudite devices. The nominal composition of the P-type material is CeFe 4 Sb 12 , the nominal composition of N-type material is Yb 0.3 co 4 Sb 12 , where CeFe 4 Sb 12 As core material P, Yb 0.3 co 4 Sb 12 As the outer cladding material N. In this example, a circular sintering mold is taken as an example, and the inner diameter of the mold is 10mm. First put the mold annular lower ram 14 and the mold lower ram 15 in the outer mold cover 13, and put the insulating material 5 between the mold annular lower ram 14 and the mold lower ram 15, and form the insulating material 5 Put a mold lower pressure head 15 into the cavity equally, adjust the position of the mold annular lower pressure head 14, the mold lower pressure head 15 and the insulating material 5 in the outer mold casing 13, so that the height of the insulating material 5 is higher than the outer mold casing 13, In the cavit...

Embodiment 2

[0063] This embodiment is to prepare a thermoelectric device with a two-stage structure and a wrapping structure. The nominal composition of the P-type material is FeNbSb-based and CeFe 4 Sb 12 The base P-type thermoelectric material, the nominal composition of the N-type material is ZrNiSn base and Yb 0.3 co 4 Sb 12 , where ZrNiSn base and Yb 0.3 co 4 Sb 12 As external cladding materials N, FeNbSb-based and CeFe 4 Sb 12 The base P-type thermoelectric material is used as the core material P. In this example, the circular sintering mold is taken as an example, first use such as figure 1 The molds shown were sintered separately, such as Figure 4 The structures shown are P-type and N-type components with electrodes. First put the mold annular lower ram 14 and the mold lower ram 15 in the outer mold cover 13, and put the insulating material 5 between the mold annular lower ram 14 and the mold lower ram 15, and form the insulating material 5 Put a mold lower pressure h...

Abstract

The invention relates to a thermoelectric component device with a wrapping body structure, comprising: a first thermoelectric material; and a second thermoelectric material that wraps the first thermoelectric material; wherein the first thermoelectric material is one of a P-type thermoelectric material or an N-type thermoelectric material, and the second thermoelectric material is the other of theP-type thermoelectric material or the N-type thermoelectric material, and the sublimation stability or oxidation resistance of the second thermoelectric material at a high temperature in the range ofoperating temperature thereof is greater than that of the first thermoelectric material.

Description

technical field [0001] The invention relates to a thermoelectric component with a cladding structure, belonging to the field of thermoelectric materials and devices. Background technique [0002] Thermoelectric power generation is a power generation technology that uses the Seebeck effect of semiconductor thermoelectric materials to directly convert heat energy into electrical energy. The thermoelectric power generation system has compact structure, reliable performance and good mobility. Since there are no moving parts, it runs without noise, wear and leakage. It is an environmentally friendly green energy technology and is suitable for recycling with low energy density. Recycling of waste heat and industrial waste heat and space applications have broad application prospects. [0003] CoSb 3 Cobalt, Half-Heusler, MnSi, Mg 2 Si, PbTe, Zn 4 Sb 3 , Clathrate, Bi 2 Te 3 The compound has relatively good thermoelectric properties and is a thermoelectric material with appli...
