Abstract: A cooling system for a data center includes: at least one liquid-cooling heat exchanger disposed above each of the integrated circuit boards to dissipate heat from a first heat source disposed on the integrated circuit board through an internal circulation coolant in the liquid-cooling heat exchanger; a liquid-cooling distributing device comprising a first pipeline in communication with the liquid-cooling heat exchanger, a second pipeline in communication with a first cooling tower, and a heat exchanger configured to cool the internal circulation coolant from the liquid-cooling heat exchanger to a first temperature through an external circulation coolant from the first cooling tower; and the first cooling tower configured to cool the external circulation coolant supplied via the second pipeline to the second temperature, wherein the first temperature is higher than the second temperature. As a result, energy consumption can be reduced and chip-level cooling can be achieved.

Abstract: A refrigeration system is provided. The refrigeration system includes: an indoor heat exchange module configured for refrigerant to absorb heat; and outdoor heat exchange modules configured for the refrigerant to dissipate heat. The outdoor heat exchange module includes a compression device, an evaporative condenser and a liquid supplement device. The outdoor heat exchange modules are switchable between a standby mode and an active mode; some of the outdoor heat exchange modules are in the active mode, and the others are in the standby mode; in the standby mode, the outdoor heat exchange module is disconnected from the indoor heat exchange module; when the outdoor heat exchange module is switched to the active mode, it is connected to the indoor heat exchange module, the compression device starts up, and the liquid supplement device supplies cooling liquid to the evaporative condenser during an startup process of the compression device.
