Planar flexible thermoelectric power generation structure

Abstract

The invention discloses a planar flexible thermoelectric power generation structure which includes a thermal conduction layer, an insulating layer, a power generation layer and a hot-end protective layer, which are sequentially arrayed and laid from bottom to top. All of the thermal conduction layer, the insulating layer, the power generation layer and the hot-end protective layer adopt flexible materials. A first flexible material and a second flexible material are closely arrayed alternatively so that the thermal conduction layer is formed. The hot-end protective layer is a flexible insulating strip. Both of the heat conduction factors of the first flexible material and the flexible insulating strip are lower than the heat conduction factor of the second flexible material. The structure increases protection of a hot end and heat radiation of a cold end, improves the temperature gradient of a thermoelectric power generator and further improves an output power and an output voltage. The thermal conduction layer provides a temperature gradient needed by the thermoelectric power generator and has a support function; the flexible materials are adopted so that compared with a rigid thermoelectric power generation device, the power generation structure is flexible, light and convenient and capable of better fitting to the plane; and the power generation structure is simple in structure and manufacturing process and capable of realizing mass production, and has an excellent application prospect.

Description

technical field [0001] The invention relates to a thermoelectric power generation structure, in particular to a planar flexible thermoelectric power generation structure. Background technique [0002] The energy crisis is becoming more and more serious, and it is urgent to actively promote and promote the use of clean and renewable energy. As a widely distributed energy source in nature, thermal energy is generated all the time. However, the utilization of thermal energy by human beings is far from enough at present, and the utilization rate is extremely low. It is of great research value to make full use of these unused heat energy in nature and convert it into electrical energy that can be stored and directly used. [0003] Since the discovery of the Seebeck effect in 1821, with the continuous research on thermoelectric materials, thermoelectric technology has received more and more attention. Thermoelectric generators use the Seebeck effect of thermoelectric semiconduc...
