Thermodynamics and Immersion cooling

Thermodynamics and Immersion cooling

Thermodynamics is an essential part of Immersion cooling, but what is it and how does it work? Our infographic details how the process works within a Submer SmartPodX and how this contributes to a better performance than other cooling technologies such as air.

What is Thermodynamics?

Thermodynamics studies how heat, work, temperature and energy are related. The laws of Thermodynamics describe how the energy of a system is balanced in respect to its surroundings.

Thermodynamics and Immersion cooling

How is the heat captured in the immersion tank and driven away from the server heat generating components (chips)?

This infographic shows the path the heat follows through the tank to the Cooling Distribution Unit (CDU), where it is then dissipated to the outside air by means of liquid loops.

The liquid enters into the tank at low temperature and it flows upwards driven by density changes when heated by the IT components. The coolant is then collected on the top surface and cooled down inside the Cooling Distribution Unit (CDU) before being delivered to the tank.​

Our Immersion tank is designed to optimize its flow interaction with the servers and to efficiently remove heat from the chips.

The benefits of Thermodynamics and Immersion cooling

The performance of the heat flow from the chip to the surrounding medium is measured by the thermal resistance. Under CPU working conditions, SmartCoolant presents case-to-media resistances from 2 – 6 times less with respect to air.

  • Boosted performance
  • Energy savings
  • Increased life-span

As you can see, thermodynamics contributes to many of the main advantages of Immersion cooling. Want to learn more about Thermodynamics? Check out our whitepaper or our webinar!
