Title: CENTRALIZED COOLING SYSTEM FOR DATA CENTER COMPUTER ROOMS
Abstract:
Disclosed in the present invention is a centralized cooling system for data center computer rooms, comprising: a hydraulic spraying apparatus and a hydraulic working medium cooling apparatus which are integrated on an outside portion of a machine cabinet, an external liquid working medium tank, and at least one machine cabinet, wherein the hydraulic spraying apparatus, the hydraulic working medium cooling apparatus, the external liquid working medium tank, and the machine cabinet are connected by means of a pipeline; the machine cabinet comprises an auxiliary machine cabinet, a server machine cabinet, a fluid inlet pipe and a backflow pipe; the auxiliary machine cabinet is provided therein with an internal liquid working medium tank, a main pipeline, and a pipeline distributor; the server machine cabinet is provided therein with a server and a plurality of spray structures, wherein a liquid working medium sprayed by a spray structure flows back to the external liquid working medium tank by means of the backflow pipe, and then enters the internal liquid working medium tank by means of the hydraulic spraying apparatus and a hydraulic circulation cooling apparatus after cooling, thus the liquid working medium does not change phases during the spraying process. The present invention has a good heat-dissipating effect, low energy consumption, simple system integration and good user experience.
