Title:
CABINET IN DATA CENTRE, AND GRAVITY SPRAYING SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/133168
Kind Code:
A1
Abstract:
Provided is a cabinet in a data centre. The cabinet comprises a cabinet body, an oil distributor and a plurality of liquid distributors. A plurality of server housings are successively mounted on the cabinet body in a high to low direction. One liquid distributor is arranged above each of the server housings. The present invention further relates to a gravity spraying system. On the one hand, cooling liquid oil is gathered in an upper oil distribution tank, and due to the action of gravity, the oil automatically flows along oil passages, and the pressures are unnecessary to be set in oil paths, thus reducing the power consumption of an oil pump, improving the efficiency (COP) of a heat dissipation system, and reducing the total PUE of the data centre. On the other hand, the problem of inconsistent oil quantity distribution of gravity oil distribution paths caused by a height difference resulting from successive arrangement of servers in the cabinet from top to bottom is solved, and oil quantity regulators in oil distribution units are used to ensure that the flow distributed to the server on each layer is consistent. The present invention has a smart design and a rational structure, involves an innovative method, makes progress on a traditional large server cooling mode, and at the same time, has strong practicability and is convenient to promote.
