Abstract

The invention discloses a two-stage thermoelectric material device comprising a base and a thermoelectric device body, wherein the upper surface of the base is provided with a groove, the thermoelectric device body is disposed inside the groove and comprises a lower substrate, an upper substrate, a conductive plate, a two-stage P-type thermoelectric element, a two-stage N-type thermoelectric element and an electrode rod, and the lower substrate is symmetrically arranged with the upper substrate. By providing a threaded column, a rotating shaft, a bearing, a pressing plate, a mounting plate anda bolt, when the thermoelectric device body is mounted and fixed, the rotation of a rotary handle drives the rotation of the threaded column to drive the rotating shaft to rotate in the bearing suchthat the pressing plate moves to the left to fix the thermoelectric device body in the groove; at the same time, a telescopic rod can be used to limit the pressing plate to improve the security assurance; by using the two-stage P-type thermoelectric element and the N-type thermoelectric element to superimpose and use the thermoelectric materials of different temperature domains in parallel, physical property characteristics of different materials can be fully utilized, so as to effectively improve the power generation efficiency of the thermoelectric device.

Description

technical field [0001] The invention relates to the technical field of thermoelectric materials, in particular to a double-stage thermoelectric material device. Background technique [0002] A unit that can independently control and transform electronic and electrical instruments is often composed of several components, and sometimes refers to larger components. Thermoelectric materials are functional materials that can convert heat energy and electrical energy. Thermoelectric material devices are used Assemblies of components made of thermoelectric materials, with the increasing interest in space exploration, the progress of medical physics, and the increasingly difficult resource exploration and exploration activities on the earth, it is necessary to develop a type of power system that can supply energy by itself and does not need to be looked after. Thermoelectric power generation is especially suitable for these applications. Both natural temperature difference and indus...
