Description
Technical field
The present invention relates to server cooling field more particularly to a kind of novel closed-type phase-change type liquid cooled server systems.
Background technique
The method of server radiating generally uses air cooling way to cool down to server.And it is all made of in air cooling way indirectly
Contact cooling mode, therefore in the cooling system of diabatic process complexity, big, convective heat transfer resistance that there are thermal contact resistances greatly,
And the problem that thermal resistance summation is big, and then cause heat exchange efficiency lower；Between the height temperature-heat-source that also guarantee heat transfer process simultaneously
The larger temperature difference, it is therefore desirable to lower outdoor low-temperature heat source guides the heat transfer process to carry out.But it for data center, only leans on
Air cooling way oneself be insufficient for requirement of the server to heat dissipation performance of high heat flux density.
Another method of server radiating is liquid cooling mode, i.e., using working fluid as the matchmaker of intermediate heat transmission
It is situated between, heat is transmitted to by hot-zone and is cooled down again at a distance.Liquid cooling mode is liquid unlike the indirect refrigeration of air cooling way
Phase refrigerant is directly directed to heat source, and more much larger than the specific heat capacity of air additionally, due to liquid, radiating rate is also far longer than air, because
The refrigerating efficiency of this liquid cooling mode compares heat that per unit volume is transmitted with air cooling way i.e. much higher than air cooling way heat dissipation
Radiating efficiency is improved up to 3300 times.
Liquid cooling system has the characteristics that balanced heating element heat and low noise work.Since the specific heat capacity of liquid is big,
Therefore a large amount of heat can be absorbed and temperature is kept significantly not change, therefore in liquid cooling system heating element temperature
It can be well controlled, burst operation will not cause heating element internal temperature moment significantly to change.
Evaporation is cooling from the thermal principle, is that latent heat of vaporization when being boiled using liquid phase refrigerant takes away heat.Due to liquid
The latent heat of vaporization it is very big, therefore transpiration-cooled cooling effect is more significant, therefore is applied in liquid cooling system.In liquid cooling system
In system, the gas phase refrigerant after the gasification of liquid phase refrigerant need to be condensed via condenser, and making it again becomes liquid liquid phase refrigerant.
In immersion liquid cooling system, refrigerant boiling generates bulk gas, is gathered in system.When gas reaches a certain amount of
When, if being vented not in time, pressure in sealing space can be made to sharply increase, so that sealing space has explosion danger.
