데이터 센터의 CDU

Data center liquid cooling solution – a full-link layout of supporting infrastructure for liquid-cooled servers. The liquid-cooled CDU distribution unit provides cooling liquid for the cold plate in the server rack, maximizing the use of the heat exchange of the liquid cooling plate to the main heat source inside the server. Cooling, reducing the use of air cooling systems, helping servers achieve greater power dissipation requirements and greater computing density in a single cabinet, further reducing PUE and assisting the high-quality development of data centers.

1. CDU in Data Center application

With its strong R&D, construction, and operation and maintenance capabilities in the field of data centers, Data has launched a new air-liquid architecture cold plate liquid-cooled CDU with a heat dissipation of up to 15kw. Relying on modular lightweight and intelligent design, the construction of edge computer rooms can be quickly completed and renovation of old computer rooms.

2. Product introduction of CDU in Data Center

CDU distribution unit liquid cooling equipment is suitable for semiconductor testing, electronic equipment constant temperature testing, cooling server supporting infrastructure, and other fluid temperature control places. It is a modular intelligent device with independent heat exchange system, power supply system and monitoring system.

3. Working principle of CDU in Data Center

The cooling water flows into the CDU distribution unit, exchanges heat with the heat transfer medium, takes away the heat of the heat transfer medium, and reaches the intended temperature. It can automatically adjust frequency according to system pressure, temperature and flow rate.

The CDU distribution unit uses liquid cooling heat exchange to cool the main heat source and reduce the use of air cooling systems. The liquid cooling equipment provides cooling fluid circulation for the heating elements, saving air heat exchange links and saving a large amount of energy consumption in the refrigeration system.

The circulation system of the CDU distribution unit adopts a fully sealed design, a magnetic drive pump, a PLC programmable controller, and a 7-inch color touch screen temperature curve display, which can be customized according to user needs.
