Chiller Liquid Cooling

Introduction to chiller liquid cooling

Chiller liquid cooling uses cooling liquid to contact the heat source for cooling. Depending on the contact heat exchange methods between the coolant and the server, they are divided into immersion type, cold plate type and spray type.

Cold plate technology is an indirect contact liquid cooling. The equipment that needs to dissipate heat is fixed on the cold plate, and the liquid transfers the heat away from the equipment through the cold plate. The cold plate type has strong compatibility and is easy to maintain. It is mainly used in standardized and general high-density data centers.

The immersion technology is a direct contact liquid cooling, which completely immerses servers and other equipment that require heat dissipation in the coolant and cools them through liquid circulation. It has higher heat dissipation efficiency, low noise and lower power density, and is mainly used in ultra-high-density data centers.

The principle of chiller liquid cooling

chiller Liquid cooling works by flowing a liquid (usually water) through the heat sink of an electronic device, absorbing the heat generated by the device, and then removing the heat, thereby lowering the temperature of the device. Liquids conduct heat better than air, so liquid cooling can remove the heat generated by the device faster.

Liquid cooling systems usually consist of radiators, water pumps, water pipes, and water tanks. A chiller liquid cooling system moves liquid through a radiator, and the fins in the radiator allow the liquid to more easily absorb the heat generated by the device. The water pump then flows the liquid with the heat into the tank, where a radiator dissipates the heat to the surrounding environment. Liquid cooling systems can control the temperature of the device by adjusting water flow and water temperature.

Chiller liquid cooling technology is mainly divided into two types: direct liquid cooling and indirect liquid cooling. Direct liquid cooling refers to flowing liquid directly through the radiator of the electronic device to remove the heat. Indirect liquid cooling involves flowing a liquid through a heat exchanger, transferring heat to another liquid through the heat exchanger, and then taking the heat away. Direct liquid cooling is more efficient but requires higher maintenance costs and a more complex design.

Applications of chiller liquid cooling

chiller liquid cooling technology can be applied to various electronic devices that require heat dissipation, such as:

High-performance computing: High-performance computers need to process large amounts of data and complex computing tasks, and generate a lot of heat. Liquid cooling technology can reduce the temperature of the computer more effectively and improve the performance and stability of the computer.

Data Center: Data centers need to handle large amounts of data and network traffic, and generate a lot of heat. Liquid cooling technology can more effectively reduce the temperature of the server and improve the performance and stability of the server.

Artificial intelligence: Artificial intelligence needs to process large amounts of data and complex computing tasks, and generates a lot of heat. Liquid cooling technology can more effectively reduce the temperature of artificial intelligence equipment and improve the performance and stability of the equipment.

Gaming PC: Gaming PCs need to handle a lot of graphics and computing tasks and generate a lot of heat. Liquid cooling technology can more effectively reduce the temperature of gaming computers and improve computer performance and stability.
