White Paper: General Guidance for Transitioning from Single-Phase to Two-Phase Liquid Cooling Solutions

The rapid expansion of artificial intelligence, high-performance computing, and cloud services is driving unprecedented levels of heat generation in modern data centers. Traditional air cooling and single-phase liquid cooling are increasingly unable to meet the demands of high-density server racks and powerful processors. Two-phase liquid cooling, which transfers heat through the phase change of the coolant, offers significantly greater thermal efficiency and the potential for substantial energy savings.

This paper reviews the key differences between single-phase and two-phase cooling, highlights the advantages of two-phase systems, and discusses critical technical challenges such as working fluid selection, boiling behavior, pressure drop management, flow configuration, and the design of quick disconnects. Practical guidance is provided for transitioning to two-phase cooling, emphasizing the importance of system integration, component compatibility, and environmental considerations. With careful planning, two-phase cooling can deliver substantial improvements in heat dissipation for demanding data center applications.
