Abstract

The invention relates to a method for improving the heat transfer of a heat exchanger in a box type thermoelectric system of an automobile. A thermoelectric module is arranged at each of the upper end and lower end of the heat exchanger respectively; a water tank is arranged above each thermoelectric module. The method is characterized in that quartz cloth is arranged between the heat exchanger and each thermoelectric module, and clings to the surfaces of the thermoelectric modules and the heat exchanger in a flat manner, so that the temperature distribution of the thermoelectric modules becomes more uniform in the normal working process of the thermoelectric system under the condition of increasing the temperature difference between cold and hot ends, and the output power and thermoelectric conversion efficiency are increased.

Description

technical field [0001] The invention relates to the technical field of a box-type automobile exhaust thermoelectric system, in particular to a method for improving heat transfer of a heat exchanger of a thermoelectric system. Background technique [0002] With the in-depth study of automotive thermoelectric systems, it is particularly important to optimize the design of the thermoelectric conversion process, improve the energy conversion rate of the system, improve the heat transfer of the thermoelectric system, and increase the output power. The output power of the thermoelectric power generation device is affected by three aspects: the specifications and performance parameters of the modules, the specifications and structure of the module array, and the temperature difference between the two ends of the modules. The temperature difference between the two ends of the thermoelectric module is the difference between the temperature of the hot end and the temperature of the co...
