Immersion cooling Technology is one of the most effective cooling methods for data centers & crypto mining 

WHAT IS LIQUID IMMERSION COOLING

In liquid immersion cooling, electronic components are immersed into a tank of dielectric liquid. Those liquids are much better heat conductors than air, water, or oil. The high temperature of the components causes the liquid to boil and drag heat to the surface.

Immersion cooling is an IT cooling practice by which IT components and other electronics, including complete servers, are submerged in a thermally conductive dielectric liquid or coolant. Heat is removed from the system by circulating liquid into direct contact with hot components, then through cool heat exchangers. Fluids suitable for immersion cooling have very good insulating properties to ensure that they can safely come into contact with energized electronic components.

The IT in an immersion tank is placed vertically within the dielectric liquid. The parts that generate heat are completely immersed in the liquid solution and the characteristics of the different fluids are making the hot liquid rise to the surface, extracting the heat from the components by dragging.

Why do we need immersion cooling

Immersion refrigeration is establishing itself in the market as an excellent alternative to solve the following challenges for the actual Market Pain Problems:

  • High OPEX & CAPEX costs 
  • High technical requirements
  • Impossibility of reaching high densities with current methods
  • Needs of many edge data centers
  • the market is expected to be driven by the growing need for green and energy-efficient alternatives to existing cooling infrastructure
  • NET ZERO path with current systems is very expensive and difficult to achieve the objectives set for the next few years.

How immersion cooling works

In immersion cooling there are two types of systems:

Single-phase 

Two-phase

What is single phase immersion cooling

In Single-Phase servers are installed in an immersion cooling with dielectric fluid. The liquid remains passive during the cooling process. This system requires circulation of the dielectric liquids by pumps or by natural convection flow. 

The liquid temperature maintains the IT and the rest equipment in a comfortable range of temperature always controllable for the tank and the technical requirements.

In terms of density can support depending on what type of liquid are you using, it can be enough to fill a dip tank without problem with values from 50 kW to 200 kW.

What is Two phase immersion cooling

In Two-Phase applications the fluid make changes phase. The boiling point of the fluid is chosen and the bubbling causes a stage change from fluid to gas, which gives two-stage drenching cooling. The vapor generated should be condensed back into the liquid form heat exchanger. Once condensed the two-phase coolant drips back into the primary cooling tank.

The temperatures of the coolant fluctuate between evaporation and cooling taking the equipment temperature with the liquid evaporation. 

Two-Phase can support extreme rack density up to 250kW per rack more than Single-Phase and the liquid is designed to evaporate when it comes to hot components.

At TEIMMERS we're capable of applying both types of liquid immersion cooling systems.

We must be aware that both technologies can be used in different industries and there is not one better than the other, but rather they are systems that can be implemented with traditional ones based on air cooling.
