Abstract: A centralized cooling system for data center comprises at least one cabinet, a spray hydraulic device and a hydraulic working substance cooling equipment integrated outside the cabinet, and an outer liquid working substance tank, which are connected by a pipe, wherein the cabinet comprises an auxiliary cabinet, a server cabinet, a liquid inlet pipe, and a return pipe; wherein an inner liquid working substance tank, a main pipe and a pipe distributor are arranged inside the auxiliary cabinet; a server and a plurality of spraying mechanisms are arranged inside the server cabinet; the liquid working substance sprayed from the spraying mechanisms is returned to the outer liquid working substance tank through the return pipe, cooled down by means of the spray hydraulic device and the hydraulic circulating cooling device, and enters the inner liquid working substance tank, and the liquid working substance has no phase transition during the spraying process.

Abstract: A data center cabinet includes a cabinet body, an oil distributor and a plurality of liquid distributors. The cabinet body is sequentially mounted with a plurality of server housings from high to low. A liquid distributor is provided above each of the plurality of server housings. The present invention also relates to a gravity spray system. On the one hand, as cooling liquid oil is concentrated in an oil distributor tank disposed above, the oil automatically flows along an oil passage under gravity, and there is no need to provide pressure in the oil passage, thus reducing the power consumption of an oil pump, improving the coefficient of performance (COP) of a heat dissipation system and reducing the overall PUE of a data center. An oil quantity regulator in an oil distribution unit is used to ensure consistent flow rate distributed to each layer of server.

Abstract: A data center cabinet includes a cabinet body, an oil distribution device and a plurality of liquid distributors. The cabinet body includes a number of mounting racks. The cabinet body is sequentially mounted with a number of server housings from high to low. A server is placed in the server housing. A liquid distributor is provided above each of the server housings. The oil distribution device is connected to the liquid distributor via an oil intake device. Cooling liquid oil is pumped into the oil distribution device by a pump, the oil distribution device distributes oil flow to the liquid distributor under the pressure of the pump, and the liquid distributor sprays the cooling liquid oil to the server for cooling. The present invention also relates to a pressure spray system.
