CDU liquid cooling chiller for data center and servers

Data center Liquid Cooling Chiller 用于数据中心/服务器冷却

For Servers Cooling/Rack Cooling

CDU will become the mainstream thermal solution in the data center. In general, cooling systems with radiators, fans, air conditioning units, etc. are considered insufficient for CPUs over 300W. To continue normal operation of the 300-1000W high-power CPU and improve computing and processing efficiency, it is necessary to properly handle the heat through the CDU.

High cooling performance is not the only advantage of the CDU: Compared with air-cooled units, its major advantage is that it consumes less power and has less loss of liquid cooling media.

Reduce the energy consumption of refrigeration systems

Use liquid cooling plate heat exchange to cool the main heat source inside the server and reduce the use of air cooling systems.

Liquid-cooled CDU provides coolant circulation for cold plates that are in direct contact with server heating components.

The coolant distribution unit of our LNEYA can be said to be a liquid-to-liquid type, which greatly reduces the ratio of high loss of coolant in the past, and has high safety and reliability.

Working principle

Indirect contact liquid cooling system: heat is exchanged with the coolant inside the server in the heat exchanger outside the server through an intermediary fluid (such as fluorinated liquid), and then the intermediary fluid is transferred to the external cooling system.

Cooling water enters the unit and exchanges heat with the thermal conductivity medium, taking away the heat of the thermal conductivity medium and reaching the predetermined temperature for use. It can automatically adjust frequency conversion according to system pressure, temperature, and flow rate.

Using liquid cooling heat exchange to cool the main heat source and reduce the use of air-cooled systems. By using liquid cooling equipment to provide cooling liquid circulation for heating elements, the air heat exchange process is saved, and a large amount of energy consumption in refrigeration systems is saved.
