Abstract
The invention relates to an electric automobile integrated type thermal management system based on a phase change material. The system comprises a battery integrated thermal management mechanism, a gearbox integrated thermal management mechanism, a motor integrated thermal management mechanism, a heat pump air-conditioning mechanism and a phase change material heat exchange mechanism. When the temperature of the outside world is in the normal working temperature range from 0 DEG C to 30 DEG C and a battery pack of an electric automobile works, generated heat is stored in a low-temperature phase change material heat exchanger, and under the condition of the temperature from 0 DEG C to -10 DEG C, the stored heat of the low-temperature phase change material heat exchanger is used for heatingthe battery pack of the electric automobile; heat generated when a gearbox works is stored in a high-temperature phase change material heat exchanger; heat generated when a motor and a circuit modulework is stored in the high-temperature phase change material heat exchanger; and under the condition of the temperature from 0 DEG C to -10 DEG C, the stored heat of the high-temperature phase changematerial heat exchanger is transmitted to the low-temperature phase change material heat exchanger through cooling liquid in the phase change material heat exchange mechanism so as to be used for heating the battery pack of the electric automobile.
Description
technical field [0001] The invention belongs to the technical field of thermal management systems for automobiles, and in particular relates to an integrated thermal management system for pure electric vehicles and hybrid vehicles based on phase change materials for batteries, motors, gearboxes and air conditioners. Background technique [0002] As environmental protection and energy issues become increasingly severe, electric vehicles, as a zero-emission, pollution-concentrated environmentally friendly means of transportation, are regarded as a substitute for traditional vehicles. [0003] During the driving process of electric vehicles, the battery pack will frequently perform charging and discharging activities, and the energy loss in this process is mainly converted into heat. Therefore, it is necessary to effectively dissipate heat from the battery pack, otherwise it will cause the battery pack to overheat, affect battery life and even cause safety hazards such as fire ...
