Flexible thermoelectricity generator and manufacturing method thereof

Abstract

The invention relates to a flexible thermoelectricity generator and a manufacturing method thereof. The flexible thermoelectricity generator and the manufacturing method thereof comprise a flexible connector. A plurality of N type thermoelectric material bodies and P type thermoelectric material bodies are arranged inside the flexible connector. One ends of the N type thermoelectric material bodies are electrically connected with one ends of the P type thermoelectric material bodies adjacent to one sides of the N type thermoelectric material bodies through a first conductive connecting layer, and the other ends of the N type thermoelectric material bodies are electrically connected with the other ends of the P type thermoelectric material bodies adjacent to the other sides of the N type thermoelectric material bodies through a second conductive connecting layer. The N type thermoelectric material bodies and the P type thermoelectric material bodies are connected in series through the first conductive connecting layer and the second conductive connecting layer to form thermoelectric material bodies, and flexible insulation protection bodies are filled in the thermoelectric material bodies. A first insulation protection layer and a second insulation protection layer cover the flexible connector. The flexible thermoelectricity generator and the manufacturing method thereof have the advantages of being compact in structure, simple and convenient in process, low in manufacture cost, high in generating efficiency and safe and reliable, and greatly expanding application range of thermoelectricity generators. In addition, the flexible thermoelectricity generator can be bent moderately.

Description

technical field [0001] The invention relates to a thermoelectric generator, in particular to a flexible thermoelectric generator and a manufacturing method thereof, belonging to the technical field of thermoelectric generators. Background technique [0002] Due to the growing miniaturization trend of portable electronic products, the research and development of miniaturized power supplies are promoted. As a self-sufficient energy source, thermoelectric generators can directly convert heat energy into electrical energy according to the Seebeck effect, and can maintain a practically unlimited effective life at a suitable temperature, which makes it a high-tech in the energy field. One of the hot spots of international research. [0003] A thermoelectric generator generally consists of three parts: a heat source, a heat sink, and a thermopile. A thermopile is a series of thermoelectric pairs connected in series that convert heat energy into electricity (Figure 2). A thermoel...
