As data centers continue to support increasingly demanding workloads such as artificial intelligence (AI), machine learning, cloud computing, big data analytics, and high-performance computing (HPC), traditional air-cooling systems are reaching their operational limits. Modern processors and high thermal design power (TDP) chips generate significant amounts of heat, requiring more advanced and efficient cooling technologies.
Delta Two Phase Immersion Cooling is an innovative thermal management solution specifically designed to address the cooling challenges of next-generation data centers. By utilizing advanced liquid immersion cooling technology, Delta delivers exceptional cooling performance, significantly lower energy consumption, and improved operational efficiency compared to traditional air-cooling systems.
The solution directly immerses servers, electronic components, and IT equipment into a specially engineered non-conductive coolant. Heat generated by the equipment causes the coolant to change phase from liquid to vapor, efficiently removing thermal energy through the natural phase-change process. This innovative mechanism eliminates multiple heat exchange stages commonly found in conventional cooling systems, resulting in superior heat transfer efficiency and substantial energy savings.
How Two Phase Immersion Cooling Works
Unlike conventional air-cooling methods that rely on fans, air circulation, and multiple cooling stages, Delta’s Two Phase Immersion Cooling technology directly cools the heat source.
The cooling process includes:
- Electronic components are fully immersed in a non-conductive dielectric coolant.
- Heat generated by processors and IT equipment causes the coolant to boil.
- The coolant absorbs heat and changes from liquid to vapor.
- Vapor rises and condenses on a cooling surface.
- The condensed coolant returns to the tank for continuous cooling.
This highly efficient cycle continuously removes heat while maintaining optimal operating temperatures for critical IT equipment.
