Immersion Liquid Cooling (Single-phase)

In the heat exchange process, based on whether the coolant undergoes a phase change, it can be categorized into two types: single-phase immersion cooling and phase-change immersion cooling. Servers orother IT components are submerged in a heat-conducting medium or coolant: the coolant remains in liquid form and does not boil or freeze. After coming into contact with the heated components, the coolant transfers heat to the cooling circuit through a heat exchanger. This technology, known as single-phase immersion cooling, achieves 100% liquid cooling and offers superior energy-saving performance. Typically, maintenance requirements for single-phase immersion cooling solutions are much lower, and any adjustments are easier to access and maintain.
