Problems solved by technology

However, limited by the manufacturing process of the thermoelectric power generation module and the existing thermoelectric power generation technology, the hot end of the thermoelectric power generation module has a certain safe working temperature. This temperature is not only related to the optimal working temperature of the thermoelectric power generation material, but also related to the The melting point of solder, etc.
The maximum temperature of the hot end of the thermoelect

Abstract

The invention discloses an automobile exhaust waste heat thermoelectric generator device adopting phase change materials. The automobile exhaust waste heat thermoelectric generator device comprises a heat conductor, which is fixedly attached to an exhaust pipe. A heat thermoelectric generator is fixedly disposed on the heat conductor, and the heat end of the heat thermoelectric generator is attached to the outer surface of the heat conductor, and the cold end of the heat thermoelectric generator is provided with a radiator. The side of inner part of the heat conductor close to the heat thermoelectric generator is provided with a phase change material accommodation cavity, in which are disposed phase change materials in a filled manner. By disposing the phase change materials on the output end of the heat conductor, the temperature of the heat end of the heat thermoelectric generator adopting the phase change materials is kept in a stable range, and therefore the performance of the heat thermoelectric generator and the stability of the output voltage are greatly improved, and the service lifetime of the heat thermoelectric generator is prolonged to a certain extent.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to an automobile exhaust waste heat thermoelectric power generation device using phase change materials. Background technique [0002] With the continuous increase of the number of automobiles, the energy consumed by vehicles is increasing day by day, and the energy saving of vehicles has attracted more and more attention. In this situation, the research and application of thermoelectric power generation technology in the utilization of waste heat from automobile exhaust continues to develop. Thermoelectric power generation is a new and environmentally friendly power generation method. Its principle is: according to the Seebeck effect, the temperature difference between the two ends of the semiconductor device connected into a galvanic pair is maintained, and a thermoelectric electromotive force will be generated in this semiconductor device. [0003] W...
