The invention provides a thermal management system and a thermal management method. The heat management system comprises a motor management system, an air conditioner management system and a battery management system. The motor management system comprises a motor, and a first heat exchanger and a second heat exchanger which are connected with the motor; the first heat exchanger is a cooling liquid-oil heat exchanger, and the second heat exchanger is a refrigerant-oil heat exchanger; the motor management system is connected with the air conditioner management system and the battery management system through a refrigerant path and a cooling liquid path. The cooling liquid-oil heat exchanger and the refrigerant-oil heat exchanger are arranged on the motor at the same time, so that the cooling efficiency of the motor at a high temperature and the heat recovery efficiency of the motor at a low temperature are improved.
本申请提供一种热管理系统及热管理方法。热管理系统包括电机管理系统、空调管理系统以及电池管理系统;电机管理系统包括电机及与电机连接的第一热交换器及第二热交换器;第一热交换器为冷却液‑油热交换器,第二热交换器为冷媒‑油热交换器;电机管理系统与空调管理系统以及电池管理系统通过冷媒路及冷却液路连接。本申请在电机上同时设置冷却液‑油热交换器及冷媒‑油热交换器,提高了高温时电机的冷却效率与低温时电机的热回收效率。
