At Computex 2017, at the stand of Gigabyte Technology, those who wished could admire the working 2U computer shelf full of liquid. This is one of the rare yet effective methods of liquid cooling of computing systems. It is not new, but for a number of reasons has not yet become widespread. Unlike traditional systems of liquid cooling, the immersion method is not afraid of leaks, since it is already completely filled with a coolant . However, working with optical communication channels,
for example, in submerged systems requires completely sealed connections, which have not yet been standardized.
In development Gigabyte for cooling of a board with accessories the "dry" liquid Novec of the company 3M is used. Of course - it's a dielectric that does not pass current. 3M has been producing Novec for a long time in different versions. For example, for automatic fire extinguishing systems. The liquid "boils" when heated above 45 degrees Celsius and quickly removes heat from the components. Later, the gas creates a pressure and again returns to the liquid
medium as a condensate.
According to the developers, for servers with full immersion in case of heat dissipation when using Novec fluid, the complex consumption of the system can be reduced by 97%. Previously, similar systems were presented by IBM and also using this liquid from 3M, but its performance indicators were slightly lower - up to 90% of consumption reduction. For comparison, dipping servers into oil (natural dielectric), with which experiments with full pouring of components began, demonstrated a decrease in
consumption at the level of 50-60%. Related Products :
