A valve device has a first switching state in which the first heat exchanger is disposed in the first circuit and the second heat exchanger is disposed in the second circuit and a second switching state in which the first heat exchanger is disposed in the second circuit and the second heat exchanger is disposed in the first circuit.

A heat management system and an electric vehicle. The heat management system may be configured in the electric vehicle. A plurality of heat management requirements are generated under different conditions such as different operating conditions (such as driving and a charging request) of the electric vehicle, a current ambient temperature of the electric vehicle, a temperature of a battery pack, or a heat status (that is, a heat value) of a power assembly. Therefore, the heat management system can select different circulation manners of a coolant for different heat management requirements. The heat management system adjusts opening or closing of each valve port in the multi-path direction control valve assembly to select different circulation manners of the coolant, to reduce energy consumption and costs generated when the heat management system performs heat management on the power assembly and the battery pack.
