Description
Technical field
The present invention relates to server field, specifically, relate to a kind of heat dissipating method and device of server.
Background technology
At present, the server radiating mode in machine room adopts air-cooled temperature-reduction method usually.But, in large-scale data center, be only not enough to by air-cooled the cooling requirements meeting high heat flux server.The mode that traditional air-cooled pattern all adopts indirect contact to cool is carried out, it has diabatic process complexity, there is thermal contact resistance and convection heat transfer thermal resistance, thermal resistance summation is large, heat exchange efficiency is lower, between heat transfer process high/low temperature thermal source, the temperature difference is comparatively large, needs lower outdoor low-temperature heat source to guide the various disadvantages such as heat transfer process carries out.
Liquid cooling, namely utilizes working fluid as the medium of middle delivered heat, is delivered to by heat cools at a distance again by hot-zone.Because the specific heat of liquid is far longer than air, radiating rate is far super air also, and therefore refrigerating efficiency is far above wind-cooling heat dissipating mode, and liquid cooling simultaneously also can be well controlled in noise.
The maximum feature of liquid cooling heat radiation system has two: the heat of balanced CPU and low noise work.Due to the specific heat capacity super large of liquid, therefore, it is possible to absorb a large amount of heats and keep temperature that obvious change can not occur, make the temperature of the CPU being placed in liquid cooling system can obtain good control, and the operation of any burst all can not cause the temperature of CPU inside to occur significantly to change instantaneously.In addition, because the surface area of heat interchanger is very large, so, in liquid cooling system, only need slow-revving fan to carry out heat radiation to it just can play good effect.Meanwhile, liquid cooling system also has the characteristic of low noise.
At present, the cooling liquid that liquid cooling server on the market adopts is mostly water.As everyone knows, there is the water of impurity to be a kind of good conductor, once occur leak and processed in time, circuit board short circuit can be caused.Although current water-filled radiator producer ensures the complete Full-sealed no-leakage of its product, this is a kind of hidden danger all the time, and most of server producer is hung back to this technology.
If use insulating and cooling liquid body to cool server, no matter be directly cool or indirectly cool, once sealing effectiveness is bad, cooling liquid steam just can be revealed and scatter and disappear, thus causes the loss of cooling liquid and the cooling performance of liquid cooling system to decline.In addition, the cooling liquid steam of leakage can increase the chemical agent concentration in confined space, even if cooling liquid is for environment and body harmless, also can make us producing worry.
In sum, no matter be adopt water or insulating and cooling liquid body, no matter radiating mode adopts directly cooling or cooling indirectly, and sealing problem is all one very important potential safety hazard for liquid cooling server.Therefore, the leakage accident that how in time, exactly the cooling device processing sealing causes, thus prevent cooling liquid from damaging server, become the problem needing solution badly.
