Abstract

A semiconductor air conditioner system of an electric automobile comprises an air blower, an air filter and a semiconductor refrigerating and heating device. One end of the air filter, one end of the air blower and one end of the semiconductor refrigerating and heating device are sequentially connected. The other end of the air filter is connected with a system air inlet. The other end of the semiconductor refrigerating and heating device is connected with a system air outlet. The semiconductor refrigerating and heating device comprises a semiconductor module and an air dividing shell which is arranged on the leeward side of the semiconductor module. The semiconductor air conditioner system is simple and compact in structure and small in occupied space, and the whole automobile installing and arranging are facilitated. The semiconductor air conditioner system can be used for refrigerating and heating of the low-speed electric automobile, and the cost is much lower than the cost of a traditional automobile air conditioner system.

Description

technical field [0001] The invention relates to a technology in the field of electric vehicles, in particular to a semiconductor air-conditioning system for electric vehicles based on the thermoelectric effect. Background technique [0002] At present, electric vehicles usually use heat pump air conditioners to realize operations such as cooling, heating, dehumidification and defogging in the vehicle. The cost of this air-conditioning system is expensive, and it is not suitable for low-end low-speed electric vehicles. [0003] The cooling and heating of semiconductor air conditioners rely on the Peltier effect of electrified semiconductors. P-type semiconductors and N-type semiconductors are connected in series. After connecting to direct current, temperature differences and heat transfer will occur at the joints. If the current direction at the joint is N→P, heat will be absorbed and the temperature will drop, which is the cold end. If the current direction at the joint is...
