Water-cooled phase-change cooling method and device for data center and machine room

Abstract

The invention discloses a water-cooled phase-change cooling method and device for a data center and a machine room. The water-cooled phase-change cooling device comprises an internal air-cooled heat absorption assembly, an external water-cooled heat dissipation assembly, a liquid inlet pipe and a steam exhaust pipe. The internal air-cooled heat absorption assembly is connected with the external water-cooled heat dissipation assembly through a steam exhaust pipe and a liquid inlet pipe, a liquid working medium of the internal air-cooled heat absorption assembly absorbs hot air in the data center and the machine room and then is evaporated into a steam working medium, and the steam working medium enters the external water-cooled heat dissipation assembly through the steam exhaust pipe; and the vapor-state working medium entering the external water-cooling heat dissipation assembly is condensed into a liquid-state working medium in the external water-cooling heat dissipation assembly, enters the internal air-cooling heat absorption assembly through the liquid inlet pipe under the action of gravity, and continuously exchanges heat with hot air flow in the data center and the machine room. The external water-cooling heat dissipation assembly and the internal air-cooling heat absorption assembly of the phase-change cooling device can be combined in a multi-group mode. The requirementfor the cold source quality is low, no energy loss exists in circulation, and the advantages of energy conservation and emission reduction can be better reflected.

Description

technical field [0001] The invention relates to a water-cooled phase-change cooling method and device for a data center and a machine room. Background technique [0002] While my country has become a major country in communication, the problem of energy consumption is also becoming more and more prominent. Now the energy consumption of the communication industry accounts for 20% to 30% of the entire industrial energy consumption, and due to the development of communication technology and communication business volume, the energy consumption is increasing every year. [0003] The development of the data center industry shows a trend towards large-scale, centralized, green, and rationalized layout. National requirements for data centers: By 2020, energy-saving and emission-reduction technologies will be fully applied to information and communication networks, and old communication equipment with high energy consumption will be basically eliminated; co-construction and sharing ...

Problems solved by technology

[0004] At present, the temperature control technology of data centers and computer rooms is mainly cooled by air conditioners. The structure of air conditioners is complex, and the cost and energy consumption are relatively high, especially energy consumption. The energy consumption of air conditioners is usually one-half of the input power of equipment. The energy consumption accounts for a large proportion, and the air conditioner does not work when the AC power failure of the base station
