Ultrahigh heat density cooling system

Abstract

The invention relates to an ultrahigh heat density cooling system, which comprises air conditioning equipment, wherein the air conditioning equipment comprises two layers of cooling cycles; a refrigerating host machine and a cooling terminal are arranged separately; and the cooling terminal and cooled equipment form a totally-enclosed air circulating system. The refrigerating host machine and cooling terminal equipment are arranged separately, and the cooling terminal and cooled equipment form the totally-enclosed air circulating system, so that the air supply distance is shorter when the cooling terminal is closer to the cooled equipment, and heat and mass transfer with the outside does not exist. By adopting the ultrahigh heat density cooling system, cooling effect is remarkably enhanced, the system runs without being interfered by external factors and a machine room environment is not influenced; furthermore, the cooling terminal is separated from the refrigerating host machine, sothat vibration produced by a compressor is avoided, and noise is greatly lowered.

Description

technical field [0001] The invention relates to a cooling system, in particular to an ultra-high heat density cooling system. Background technique [0002] High-performance computers (also known as supercomputers) for scientific computing have developed from petaflops to petaflops. At the same time, Internet information service companies have successively established huge data centers. With the continuous growth of the scale of two typical supercomputing platforms, computing centers and data centers, the demand for ultra-high heat density cooling systems is becoming more and more urgent. [0003] The current cooling strategy for ultra-high heat density cabinets or blade servers is to set a special high heat density area, set a limited special area in the computer room to provide strong heat dissipation, and limit the high heat density cabinets to this area. When a dedicated high thermal density zone is identified, users can apply specific high thermal density technology in...

Problems solved by technology

[0006] In order to solve the defects in the above prior art that the cooling system is easily disturbed by external factors and will cause vibration and noise, an ultra-high-density cooling system is provided, which includes air-conditioning equipment, and the air-conditioning equipment includes two layers of cooling cycles. The first cooling cycle includes pumps, air-fluid heat exchangers, and fluid-fluid heat exchangers. The cooling cycle uses volatile working fluids to transfer heat; the second cooling cycle transfers heat from the fluid-fluid heat exchangers to the environment. A cold water system or a vapor compression system that transfers heat from a fluid-fluid heat exchanger to the environment. The cooling host and the cooling terminal of the air conditioner are arranged separately, and the cooling terminal and the rack server form a fully enclosed air cooling cycle system
