Intel and Submer are collaborating on a new heatsink capable of dissipating 1000W. For the average person, such power may be out of reach, but in the world of servers, it can happen very quickly. That’s why brands are turning their attention to immersion heatsinks!
Immersion heatsinks: towards 1000W cooling capacity?
At present, tests have been successfully carried out on processors consuming 800W of power. But in the future, companies intend to make the heatsink efficient enough to handle CPUs generating 1000W of heat!
To achieve this, the Spanish company Submer is relying on the concept of forced convection heatsinks. At present, we don’t know much about this cooling system, but it takes the form of a copper cooler. The latter is enclosed in a transparent housing on which two fans appear to be mounted.
The question now is how this solution works. However, we can well imagine this assembly being totally immersed in a reservoir of non-conductive heat-transfer fluid. Demonstrations of this kind of system already exist, notably from Der8auer and Caseking. As for the fans, we imagine they will be there to force the liquid into and out of the block, hence the “forced convection” aspect.
The other advantage of this solution, according to Submer, is very low production costs. In any case, we expect to learn a little more in the next few days.
