Amidst the rapid advancements in AI computing power, high-power power supplies, and energy storage systems, traditional air cooling and cold-plate liquid cooling methods are increasingly struggling to meet the heat dissipation demands of ultra-high-power-density load testing. Leveraging the inherent advantage of comprehensive direct-contact cooling, immersion liquid-cooled dummy loads have emerged as the industry's preferred solution for high-efficiency and reliable thermal management.
Unlike cold-plate liquid cooling—which provides only indirect cooling to core components and still necessitates auxiliary air cooling—immersion liquid cooling involves fully submerging the load units within a dielectric cooling fluid. This method rapidly dissipates heat through either sensible heat transfer or latent heat of phase change, thereby eliminating localized hot spots and ensuring temperature uniformity with a deviation of less than ±2°C. This technology achieves a power density exceeding 200 kW per cabinet, features lower thermal resistance, and boasts a Power Usage Effectiveness (PUE) as low as 1.04. It reduces energy consumption by over 40% compared to traditional solutions and also facilitates the recovery and reuse of waste heat.
Furthermore, this solution eliminates the need for cooling fans and complex piping, resulting in a more compact cabinet footprint, quieter operation, and enhanced overall reliability. Our company specializes in the R&D and manufacturing of immersion liquid-cooled dummy loads, backed by extensive experience in the successful implementation of large-scale projects. Our products offer customizable specifications—including power capacity, voltage, and control modes—to meet specific client requirements. We provide customers with stable, efficient, and energy-saving one-stop load testing solutions, thereby enabling safer, more efficient, and greener testing environments for high-power equipment.
