Abstract: The technology of this application relates to a heat exchange system. The heat exchange system includes a multi-way valve, an air duct, and at least one heat exchanger disposed in the air duct. The heat exchange is provided with an air channel through which air passes, a water inlet and a water outlet of the at least one heat exchanger communicate with the multi-way valve through a water pipe group, a refrigerant inlet of the at least one heat exchanger communicates with a refrigerant outlet of the at least one heat exchanger through a refrigerant pipe group, and an electronic expansion valve is disposed on the refrigerant pipe group. The multi-way valve is further configured to communicate with a heat exchange unit, and when heat exchange is performed on the heat exchange unit, the multi-way valve makes the heat exchange unit, the multi-way valve, the water pipe group, and the heat exchanger be in one circulation loop.

Abstract: Embodiments of this application disclose a vehicle thermal management system and method. The system includes a refrigeration cycle system, a coolant cycle system, and a control device, where the coolant cycle system includes a coolant cycle frontend radiator, a power assembly heat dissipation system, a battery pack heat dissipation system, a primary path water pump, a bypass water pump, and a valve bank system. In the system, the refrigeration cycle system is connected to the primary path water pump. Furthermore, in the system, the power assembly heat dissipation system and the battery pack heat dissipation system share the refrigeration cycle system and the coolant cycle frontend radiator by using the primary path water pump, the bypass water pump, and a combination of the valve bank system.
