After sinking a complete data center, Microsoft is now also experimenting with immersing a server rack as a cooling method.
This is done by placing the server in a bath that is filled with coolant. This non-conductive fluid based on fluorine and carbon boils at 50 degrees Celsius.
The heat generated by the components is very efficiently transferred to the liquid, which boils and releases its heat when condensing.
This ensures a closed system, in which the condensed liquid drips back into the container.

This method is cost effective, because the servers can be placed closer together, which saves space. In addition, much less energy is required than for a 2-phase cooling system based on water.
There is no need for a pump to move the liquid through the tank, and the condenser does not need a cooler.

Traditionally, data centers are cooled with air, but an enormous amount of water is needed to cool this air.
Eliminating this water consumption significantly reduces the impact of a data center on the environment, according to the vice president of Microsoft's data center development group, Christian Belady.

Not the first time I heard of an immersive computer. But its definitely a very rare type of computer cooling. So its really awesome whenever I hear about it. 3M has been making plenty of Fluorinert (https://en.wikipedia.org/wiki/Fluorinert) for this process. But its quite expensive. I'm not sure its very clear when, or how it could be cost-effective.

Still, I welcome the experimentation!
