Thermoelectric generator and thermoelectric device convenient for free expansion of power parameter

Abstract

The invention discloses a thermoelectric generator and a thermoelectric device convenient for free expansion of power parameters. The thermoelectric device comprises a main body and four groups of external output terminals, wherein the main body comprises a thermoelectric module, an anode inner lead, a cathode inner lead, the anode inner lead and the cathode inner lead extend at the periphery of the thermoelectric module; the four groups of external output terminals are arranged around the main body; an anode output terminal electrically connected with the anode inner lead and a cathode output terminal connected with the cathode inner lead are arranged on each lateral side of the main body; and each output terminal comprises a pin part extending at the exterior of the main body and a wiring body formed on the pin part. According to the thermoelectric generator and a thermoelectric device, the complete standardization production of the thermoelectric module is realized, the output parameter diversification of the thermoelectric generator is realized, and desired output parameters can be customized and changed according to requirements of clients rapidly.

Description

technical field [0001] The invention belongs to the field of thermoelectric device packaging, and in particular relates to a thermoelectric generator and a thermoelectric device which facilitate the free expansion of power parameters. Background technique [0002] Thermoelectric devices refer to a type of electronic components that can directly realize the mutual conversion of electric energy and thermal energy. Its core is a thermoelectric module composed of multiple groups of P and N-type thermoelectric materials connected in series and parallel. [0003] The application of thermoelectric devices has a history of more than 100 years. In the early days, it was mainly used to detect temperature. Later, with the development of high-performance thermoelectric materials, it was widely used in electronic temperature control, waste heat power generation and other fields, such as: boiler or Recycling of waste heat from automobile exhaust, utilization of solar and geothermal resour...
