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.
