Center of data of immersion type liquid cooling: Type selecting of cooling fluid of center of data of immersion type liquid cooling and compatibility check
As the flying development of IT, data center already became the important infrastructure that props up modern economy society. In data center domain, technology of immersion type liquid cooling because its the advantage such as efficient, energy-saving, environmental protection, make the central point that the industry pays close attention to gradually. Article general spreads out development to discuss around type selecting of cooling fluid of center of data of immersion type liquid cooling and compatibility test.
One, overview of center of data of immersion type liquid cooling
Technology of immersion type liquid cooling is one kind immerses the equipment such as the server directly in cooling fluid, through liquid heat conducts character to realize equipment to come loose hot technology. The photograph is colder than traditional wind medicinal powder hot means, immersion type liquid cooling has the following advantage:
1.Medicinal powder thermal efficiency is tall: Liquid heat conducts coefficient outclass air, can transmit quantity of heat cooling fluid from equipment quickly in, implementation is efficient medicinal powder hot.
2.Energy-saving environmental protection: Technology of immersion type liquid cooling can reduce data center specific power consumption, reduce carbon to discharge, accord with requirement of green environmental protection.
3.Noise is low: Because equipment immerses directly,be in the liquid, reduced fan to wait medicinal powder the noise of hot equipment, create a quiet working environment for data center.
2, type selecting of cooling fluid of center of data of immersion type liquid cooling
Cooling fluid is the core component of center of data of immersion type liquid cooling, its function affects data center directly medicinal powder hot effect. When choosing cooling fluid, should consider the following factor:
1.Heat conducts function: The heat of cooling fluid conducts coefficient to answer taller, in order to ensure quantity of heat can be delivered quickly.
2.Chemical stability: Cooling fluid should have good chemical stability, avoid to produce chemical reaction with equipment material, cause equipment breakdown.
3.Heat up coefficient of expansion: The hot coefficient of expansion of cooling fluid should with equipment material close, be out of shape in order to reduce the facility that because of temperature change causes.
4.Security: Cooling fluid should avirulent, harmless, ensure personnel is safe.
5.Cost: The price of cooling fluid should reasonable, reduce cost of data center operation.
Current, the cooling fluid of common center of data of immersion type liquid cooling on the market basically has the following kinds:
1.Aqueous solution: If go aqueous solution of ionic water, glycol. Aqueous solution has good heat to conduct function and chemical stability, but get pollution easily, need to change regularly.
2.Blame aqueous solution: If mineral oil, fluorine turns juice,wait. Blame aqueous solution has better chemical stability and security, but hot conductibility can be opposite poorer.
3.Mixture solution: Mix aqueous solution and blame aqueous solution by certain proportion, with give attention to two or morethings heat conducts function and chemical stability.
3, compatibility of cooling fluid of center of data of immersion type liquid cooling checks
To assure the function of cooling fluid of center of data of immersion type liquid cooling, need to undertake to its compatibility checks. Test content includes:
1.Material compatibility: Check the compatibility of cooling fluid and material of data center facility, ensure happen without chemical reaction.
2.Heat conducts function: The heat that checks cooling fluid conducts coefficient, ensure medicinal powder hot effect.
3.Stability: Check the chemical stability of cooling fluid, ensure use for a long time without the problem.
4.Security: The noxiousness that checks cooling fluid, caustic wait, ensure personnel is safe.
4, summary
Center of data of immersion type liquid cooling serves as a kind of efficient, energy-saving, environmental protection medicinal powder hot technology, in data be appreciative region has wide applied perspective. When type selecting cooling fluid, need to consider its heat integratedly to conduct the function, chemical stability, element such as security. In the meantime, undertake to cooling fluid compatibility checks, ensure its function satisfies data center requirement. As ceaseless development of the technology, center of data of immersion type liquid cooling will be in prospective data center to get the effect with region mainer and mainer play.
