What's Immersion Cooling?
Also known as liquid submersion cooling. It is the practice of
submerging computer components (or full servers) in a thermally,
but not electrically, conductive liquid (dielectric coolant)
allowing higher heat transfer performance than air and many other
benefits.
Why many large data centers have already moved or are considering
the move to immersion cooling?
| 1. Up to 25% increase in power efficiency |
| 2. Up to 80% cost reduction |
| 3. Up to 60% hashrate increase |
| 4. 50%+ equipment lifespan. |
Introduction of Two-phase Liquid Cooling:
The cooling liquid undergoes a phase change in the process of
circulating heat dissipation. The cooling liquid takes away the
heat from the server and then undergoes a phase change
gasification. The gaseous cooling liquid is condensed by the
condenser and becomes liquid again and returns to the liquid
cooling tank; the cooling liquid can use 3M electronics The boiling
point of the coolant FC-72 and FC-72 is above 50℃.
In this case, the temperature of the water in the condensing coil
does not need to be too low. The use of a dry cooler can meet the
heat exchange requirements and take away the heat.
The two-phase liquid cooling has a high heat transfer efficiency
due to the phase change of the electronic cooling liquid.
The disadvantage is that during this phase change, the electronic
fluorinated liquid will escape during the vaporization process, so
there is a certain degree of tightness of the container. However,
it should not be too sealed to prevent the cooling system from
being interrupted and the cylinder explosion event, so certain
safety facilities need to be set up.
