Abstract

The invention relates to a flexible thermoelectric conversion system and a manufacturing method of the flexible thermoelectric conversion system. The flexible thermoelectric conversion system comprises a flexible thermoelectric generator and a flexible conversion circuit. The flexible thermoelectric generator comprises a first flexible substrate and a second flexible substrate. A plurality of alternately distributed N-type thermoelectric material particle bodies and P-type thermoelectric material particle bodies are arranged between the first flexible substrate and the second flexible substrate. After being connected with the P-type thermoelectric material particle bodies in series, the N-type thermoelectric material particle bodies are electrically connected with the P-type thermoelectric material particle bodies through a first conductive connecting layer on the first flexible substrate and a second conductive connecting layer on the second flexible substrate so as to form thermoelectric material bodies between the first flexible substrate and the second flexible substrate. The thermoelectric material bodies are packaged between the first flexible substrate and the second flexible substrate through flexible insulation heat-insulation potting material bodies. The flexible conversion circuit is electrically connected with the thermoelectric material bodies. The flexible thermoelectric conversion system has the advantages of simple and convenient process, low manufacturing cost, high generating efficiency, and safety and reliability, and the application range of thermoelectric generators is expanded.

Description

Technical field [0001] The invention relates to a thermoelectric conversion system, in particular to a flexible thermoelectric conversion system and a manufacturing method thereof, and belongs to the technical field of thermoelectric conversion. Background technique [0002] Due to the increasing miniaturization trend of portable electronic products, the research and development of miniaturized power supplies have been promoted. As a self-sufficient energy source, thermoelectric generators can directly convert thermal energy into electrical energy according to the Seebeck effect, and can maintain a practically unlimited useful life at a suitable temperature. This makes it a high-tech in the energy field. One of the hot spots of international research. [0003] The thermoelectric generator is generally composed of three parts: heat source, heat sink and thermopile. A thermopile is composed of a series of thermoelectric pairs that can convert thermal energy into electrical energy (...
