Resumen de: WO2026051698A1
The present application provides a thermal management system for dissipating heat from a battery pack, and an energy storage device. In the thermal management system, an output end of a compressor is in communication with a condenser and is connected to an evaporator, and is also directly connected to an input end of the evaporator by means of a bypass branch. The input end of the evaporator can selectively receive a low-temperature refrigerant from the condenser and a high-temperature gaseous refrigerant from the compressor, and the two are mixed in the evaporator, so that the low-temperature refrigerant is heated by the high-temperature gaseous refrigerant. Thus, in a low-temperature environment, the degree of superheat of a refrigerant flowing out of the evaporator can be effectively increased, preventing liquid refrigerant from being drawn into the condenser under low-temperature conditions, and eliminating the risk of drawing in air together with liquid in the condenser, thereby increasing the reliability of operation of the condenser in a low-temperature state.
