The Danes chill out – installing the liquid cooling system from CoolIT at the Centre for Biological Sequence Analysis at Denmark’s Technical University
fine-tune the porous media to go from 20,000 to70,000 W/(m2
K).
It is not related to the design: it is the way we are able to transform the powder that gives our product so much efficiency.’ Te Calyos proposition, he insisted, was not just an elegant design concept, but expertise in the manufacturing process as well. Passive cooling through a

the working fluid, but it is also ‘naturally automatic’ so there is no need for control equipment either, and, because it is a completely sealed unit with no moving parts, there is no maintenance requirement either. Vuckovic pointed out that because the working fluid is a dielectric: ‘Even if someone breaks a tube, you don’t have any damage to the electronics. It is a metal pipe, which means it is

more expensive than plastic, but it is more secure.’ Te Calyos system takes
the heat to the edge of the server, and it now has three systems for rejecting heat to the environment. Its first product was a bespoke water heat exchanger, but at ISC High Performance in Frankfurt, it will be demonstrating an air heat exchanger. Tis liquid enhanced air cooling system represents an
evolution in Calyos’ thinking about the role that its technology can play. Originally, its focus was on
highly customised, high-end liquid to liquid systems and while it is continuing with this product line, it sees a potentially bigger market for an intermediary between pure air and pure liquid cooling systems. Air cooling works efficiently on processors whose power
