Publication number: 20240130086Abstract: A multimode immersion cooling system includes a first, single-phase immersion cooling mode and a second, two-phase immersion cooling mode. The system operates in a single phase mode and reserves a two-phase mode for peak energy consumption periods. A single thermal transfer fluid is used for both modes, remaining in a liquid phase in a first single-phase immersion cooling mode and vaporizing when the thermal transfer fluid temperature reaches its boiling point in a second two-phase immersion cooling mode. A heat exchanger extracts thermal energy from heated thermal transfer fluid in the single phase mode while a condenser cools vaporized thermal transfer fluid to condense the vapor during the second, two-phase immersion cooling mode. A controller determines whether the multimode immersion cooling system operates in the single-phase mode or the second two-phase mode, or both.Type: ApplicationFiled: December 22, 2023Publication date: April 18, 2024Inventors: Wai Chung LI, Chi Ho KWOK
