High-Performance Computing (HPC) clusters generate extremely high heat densities due to continuous, parallel processing workloads. Traditional air cooling struggles to handle rack power densities beyond 30–40 kW, leading to increased energy consumption and thermal bottlenecks. Immersion cooling coolers—typically high-temperature dry coolers integrated with liquid loops—provide an efficient, scalable, and sustainable thermal management solution for HPC environments.
In immersion cooling systems, servers are fully or partially submerged in a dielectric fluid that directly absorbs heat from CPUs, GPUs, memory, and power electronics. The heated dielectric fluid transfers energy to a secondary coolant loop through a liquid-to-liquid heat exchanger. The immersion cooling cooler (dry cooler) then rejects this heat to ambient air without the need for mechanical chillers.
1. Ultra-High Heat Density Support
Immersion cooling coolers can support rack power densities exceeding 100 kW, making them ideal for GPU-accelerated HPC clusters and AI workloads.
2. Superior Energy Efficiency
High operating liquid temperatures (40–65 °C) enable year-round free cooling in most climates, significantly reducing PUE and operating costs.
3. Chiller-Free Operation
Dry coolers eliminate the need for traditional chillers, simplifying infrastructure and improving system reliability.
4. Enhanced Hardware Reliability
Uniform liquid cooling removes hot spots, reduces thermal stress, and extends the service life of HPC components.
5. Reduced Noise and Airflow Requirements
With minimal internal airflow, fan usage inside servers is drastically reduced, lowering noise and parasitic power consumption.
High-Efficiency Finned Heat Exchangers
