Rack-mounted / liquid-to-liquid
Rack-mounted Liquid-to-Liquid CDU
The rack-mounted liquid-to-liquid CDU is a core liquid cooling device designed specifically for high power density cabinets in data centers. It consists of modules such as the heat dissipation module, pump drive module, voltage stabilization module, control module and power supply module. Through heat exchange via the plate heat exchanger, cooled liquid is sent to the heat source to absorb heat, and the heat-carrying liquid then re-enters the plate heat exchanger for heat exchange treatment.

Reference conditions & selection notes
- The source does not unambiguously attach a model-specific rating matrix to this 4U product. The large CDU-900LF3S/D through CDU-1800LF3S/D table is preserved with the room-level CDU; slide 4 contains a separate, inconsistently labeled reference table.
