Fluorinated liquid is a chemical solvent that is colorless and transparent. Perfluorinated liquid has good chemical inertness, electrical insulation properties, thermal conductivity, and unique low surface tension. It is widely used in semiconductor manufacturing plants as a thermal conduction medium. Initially, it was a circuit board cleaning fluid, and its insulating and non flammable inert characteristics were applied to data center liquid cooling, making it the most widely used immersion coolant currently. It has good chemical inertness and does not corrode electronic components when in contact. After use, it does not require specific cleaning steps, making it widely used as an electronic testing fluid. Meanwhile, due to its excellent thermal conductivity, it is also used as a stable coolant.

Liquid cooled server refers to a type of server in which liquid is injected into the server and the heat is dissipated through cold and hot exchange. There are two types of servers based on their physical form: cold plate liquid cooled servers and fully submerged liquid cooled servers.
Cold plate liquid cooling technology utilizes working fluid as an intermediate medium for heat transfer, transferring heat from the hot zone to a distant location for further cooling. In this technology, the working liquid is separated from the cooled object, and the working liquid does not directly contact electronic devices. Instead, the heat of the cooled object is transferred to the refrigerant through efficient heat conduction components such as liquid cooling plates. Therefore, cold plate liquid cooling technology is also known as indirect liquid cooling technology. This technology directly directs the coolant to the heat source, and due to the higher specific heat of liquid than air, the heat dissipation speed is much faster than that of air. Therefore, the refrigeration efficiency is much higher than that of air cooling. The heat transferred per unit volume, or heat dissipation efficiency, is up to 1000 times higher, which can effectively solve the heat dissipation problem of high-density servers, reduce the energy consumption of the cooling system, and reduce noise.
Immersion liquid cooled server, in the immersion liquid phase change cooling system, the server motherboard, CPU, memory and other high heat generating components are completely immersed in the refrigerant. In the working state, each heating component will generate heat, causing the refrigerant temperature to rise. When the temperature of the refrigerant rises to the boiling point corresponding to the system pressure, the refrigerant undergoes a phase change from liquid to gas, and heat is transferred by absorbing heat through vaporization. This technology of cooling by absorbing heat through the refrigerant is called phase change liquid cooling technology. Immersion phase change liquid cooling technology utilizes liquid phase change to directly remove heat, reducing the thermal resistance of the heat transfer process. Compared with cold plate liquid cooling, immersion liquid cooling technology has higher heat transfer efficiency and is the most energy-efficient and efficient emerging refrigeration mode among liquid cooling.
