Abstract: A refrigerant pump and a data center cooling system. The data center cooling system includes a refrigerant connected between a condenser and an evaporator. The refrigerant includes a housing, a partition plate, and a pump head. The housing is provided with a liquid inlet and a liquid outlet. The partition plate is disposed inside the housing, and they jointly form first space and second space. A pump body includes the pump head and a motor. An inlet of the pump head is located at the bottom of the first space in a gravity direction. The motor is located in the second space. The pump head is configured to transfer refrigerant in the first space to the second space. The liquid inlet is directly connected to the condenser by using a pipeline. The first space is configured to store refrigerant of the data center cooling system.

Abstract: An energy storage system and a temperature control are provided in this application, and the energy storage system includes a main control module, a battery module, and a temperature control apparatus. The battery module includes a battery monitoring unit and a battery pack, the battery monitoring unit includes a battery management system and a DC/DC power converter, and the main control module is configured to control the temperature control apparatus to choose to transport a heat conduction medium to the battery module along at least one of a first path and a second path. The heat conduction medium along the first path reaches the battery pack after passing through the battery monitoring unit, and the heat conduction medium along the second path reaches the battery monitoring unit after passing through the battery pack.
