Abstract

The invention discloses an automobile exhaust waste heat efficient energy recovery device and a design method. Based on the thermoelectric power generation technology, the heat pipe technology and the heat conduction fins are combined and applied to a cold and heat source of the energy recovery device, and efficient recovery of automobile exhaust waste heat and rapid cooling of cooling water are achieved. In the design process, material selection and structural design are mainly carried out on the overall structure of the thermoelectric power generation device and key components including a thermoelectric power generation assembly, a heat exchanger, a heat pipe and a cooling water tank in the thermoelectric power generation device, and heat, electricity and structure coupling simulation and optimization are carried out on the device. The overall effective output power and thermoelectric conversion efficiency of the thermoelectric power generation assembly are improved to the maximum extent, and efficient energy recovery of automobile exhaust waste heat is achieved.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery from automobile exhaust exhaust, in particular to a high-efficiency energy recovery device and design method for waste heat from automobile exhaust. Background technique [0002] At present, the thermoelectric effect can be divided into Seebeck, Peltier and Thomson effects. Thermoelectric power generation is based on the Seebeck effect of thermoelectric power generation materials. When there is a difference in temperature between the two ends of the thermoelectric material, an electromotive force will be formed at both ends of the material and a current will be generated. , to realize the direct conversion of thermal energy into electrical energy. The thermoelectric conversion efficiency of a conventional thermoelectric generator is less than 10%, and in the existing automobile exhaust waste heat energy device, a flat-plate type thermoelectric power generation device is generally used,...
