A multi-mode heat management system for an electric vehicle comprises a vehicle cabin external heat exchanger used for exchanging heat with the external environment of a vehicle cabin, a vehicle cabin internal heat exchanger used for exchanging heat with the internal environment of the vehicle cabin, a battery heat exchanger used for exchanging heat with a battery and a pipeline allowing a heat exchange medium to flow. The pipeline is connected with a compressor, a gas-liquid separator and a bubble pump, two ends of the battery heat exchanger are respectively connected with the bubble pump, the system further comprises a temperature sensor and a controller, and the controller can receive the temperature measured by the temperature sensor, compare the temperature with a threshold temperature and respectively control the on-off states of a plurality of electromagnetic valves. And the system is switched to multiple modes. The heat exchanger in the automobile cabin and the battery heat exchanger can work in a matched mode according to specific conditions, heat waste is reduced, the air lift pump can drive the heat exchange medium to flow in the battery heat exchanger, energy consumption of the compressor is reduced, the energy utilization rate is increased, the size of a heat management system is reduced, and the endurance mileage of the electric automobile is increased.

    一种用于电动汽车的多模式热管理系统,包括用于与车舱外部环境进行换热的车舱外换热器、用于与车舱内部环境进行换热的车舱内换热器、用于与电池进行换热的电池换热器、以及供换热介质流动的管路,管路上连接有压缩机、气液分离器和气泡泵,电池换热器的两端分别与气泡泵连接,该系统还包括温度传感器和控制器,控制器能够接收温度传感器测量的温度并与阈值温度进行对比并分别控制多个电磁阀的通断状态,使系统切换至多种模式。使车舱内换热器和电池换热器能够根据具体情况配合工作,减少了热量的浪费,并且气泡泵能够能够带动换热介质在电池换热器内流动,减少压缩机的能量消耗,提升能量利用率,减少热管理系统的体积,提升电动汽车的续航里程。
