Immersion cooling
Immersion cooling is a type of liquid cooling used to moderate data center equipment temperature by submerging it in a cooling fluid. Server immersion cooling helps to dissipate heat and keep components like CPUs performing optimally. Immersion cooling systems prove to be more efficient than traditional data center cooling methods (like computer room air conditioning, or CRAC) due to the increased thermal conductivity of most liquids compared to air.
Example of an Immersion CoolingDataCenter
Given that 1-1.5% of global electricity consumption is attributed to data centers, companies have been striving to innovate and discover a liquid cooling solution capable of reducing this energy demand. One potential solution is dielectric fluid immersion cooling, which has the potential to enhance CPU density in data centers while minimizing energy consumption.
Dielectric liquid cooling involves the use of a thermally conductive but non-electrically conductive fluid that does not interfere with the functionality of electrical components such as servers. Examples of dielectric fluids encompass mineral oil hydrocarbons, synthetic fluorocarbons, and silicone fluids.

- Immersion Cooling vs. Liquid Cooling In essence, immersion cooling is a specific type of liquid cooling technique explored within a broader category. Other liquid cooling methods include direct-to-chip (DTC), rear-door server rack cooling, waterborne data center cooling, and evaporative cooling.
- Immersion Cooling vs. Server Rack Water Cooling In immersion cooling, entire data center components are submerged directly into a specially designed tank. In contrast, water-cooled server racks resemble traditional rack-mount servers but are equipped with waterblocks and tubing that circulate fluid to aid in heat dissipation.
- How Does Immersion Cooling Work? At its core, the process of cooling data center components through liquid immersion entails immersing them in a dielectric fluid. The specifics of the process vary considerably depending on whether a two-phase or single-phase immersion cooling system is employed.
