Planar flexible thermoelectric power generation structure

Abstract

The invention discloses a planar flexible thermoelectric power generation structure. It includes a thermal conductive layer, an insulating layer, a power generation layer and a hot end protective layer arranged in sequence from bottom to top; the thermal conductive layer, the insulating layer, the power generation layer and the hot end protective layer are all made of flexible materials, and the first flexible material and the third Two flexible materials are closely arranged to form a thermal conductive layer. The hot end protective layer is a flexible insulating strip. The thermal conductivity of the first flexible material and the flexible insulating strip is both lower than the thermal conductivity of the second flexible material. The invention increases the protection of the hot end and the heat dissipation of the cold end, improves the temperature gradient of the thermoelectric generator, and further increases the output power and output voltage; the heat conduction layer provides the temperature gradient required by the thermoelectric generator and has a supporting effect; it adopts flexible materials and is relatively Compared with rigid thermoelectric power generation devices, it is more flexible and lighter, and can better fit a flat surface; it has a simple structure and manufacturing process, can achieve mass production, and has good application prospects.

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...
