Background technique
Computer used at present depends on greatly cold air to machine cooling, but in data center, only by it is air-cooled
It is insufficient for the cooling requirements of high heat flux server.Traditional air-cooled mode be all made of the cooling mode of mediate contact into
Row, in diabatic process complexity, and there are thermal contact resistance and convective heat transfer resistances, and thermal resistance summation is big, and heat exchange efficiency is lower, heat exchange
The temperature difference is larger between process height temperature-heat-source, needs lower outdoor low-temperature heat source that heat transfer process is guided to carry out.
Therefore, in order to which the radiating requirements for meeting server generally use the mode of water cooling or liquid cooling in the prior art as clothes
Business device heat dissipation.Water cooling or liquid cooling have a two big benefits: first, water cooling or liquid cooling can be directly directed to coolant heat source, rather than
The indirect refrigeration as air-cooled；Second, compared with wind and cold, the heat that per unit volume is transmitted i.e. radiating efficiency is up to 3500
Times.
Evaporation is cooling from the thermal principle, is that latent heat of vaporization when being boiled using refrigerant takes away heat.Due to liquid
The latent heat of vaporization is more much bigger than specific heat, therefore transpiration-cooled cooling effect is more significant.
For liquid cooled server, heat, or the phase using refrigerant either are taken away using the temperature rise of refrigerant
Heat is converted to cool down server master board, before refrigerant enters every row's blade server, has been both needed to a liquid distribution,
The liquid distribution evenly distributes cold fluid to each blade server in the group.
Therefore, whether liquid separation uniformly has vital influence to the liquid cooling effect of blade server to the dispenser, if
Liquid separation is uneven, and the refrigerant of distribution is then fewer, and the intracorporal rate of gasification of the blade cavity is bigger, so that flow resistance is bigger,
Cause the refrigerant flow for being assigned to the blade smaller, to cause vicious circle.Being assigned to the less blade of refrigerant may
It can radiate bad, even result in refrigerant dryouies phenomenon, so that cpu temperature sharply increases, CPU is caused to damage.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Summary of the invention
For the problems in the relevant technologies, the present invention proposes a kind of cooling system of server, can will be through supercooling at
Cooling liquid after reason is evenly distributed in each Control device of liquid cooling, unevenly causes to service so as to avoid due to liquid separation
Device radiates bad drawback, ensure that the safety of liquid cooled server.
