Data Centre Liquid Cooling (Liquid & Liquid series)CDU
PRODUCT DETAIL
The cooling capacity distribution controller is a CDU liquid cooling control unit that can be installed in a 19-inch standard server cabinet. Through liquid-liquid exchange, the system can provide a safe, reliable, and clean liquid cooling circulation system control for liquid-cooled server.
Deployment &Connection
Designed as a 6Urack-mount unit, the CDU installs side-by-side withservers.lt connects to the supply/return liquidports of CPU/GPU cold plates via quick-connectfittings and short-distance pipelines.
Liquid &Liquid CDU
·Rack Integration: Designed for direct installation within server racks to achieve compact, close-proximity cooling.
·Localized Heat Dissipation: Efficiently manages coolant distribution and heat exchange for single or a few cabinets, targeting local hotspots.
·Flexible Expansion: Modular design allows flexible deployment and scaling to meet demand, suitable for high thermaldensity areas.
Manifold
·Connects CDUs to server cold plates, distributes low-temperature coolant, and collectshiah-temperature coolant.
·Balances flow to prevent local overheating and supports hot-swapping to reduce maintenance costs.
·Adapts to liquid cooling needs of multiple power architectures, helping optimize cabinet PUE and improving heat dissipation reliabilit.

Liquid-Cooled Rear Door
·Active Heat Dissipation: Equipped with fans or pumps, forcing airflow through the heat exchanger to more efficienthremove server heat.
·High-Density Eficiency: Handles ultra-high-density cabinets, delivering exceptional cooling performance while maintain.ing stable data center temperature.
·Precise Control: Adiusts fan or pump speed based on load for finer cooling management and energy savings.
Water Pump
·Drives power for the entire full liquid cooling system, circulating the coolant.
·Works with water manifolds to regulate flow, ensuring uniform heat dissipation forend equipment.

·Collaborates with the water tank to supplement pressure and vent air, maintainingsystem stability.
Water Tank
·Stores sufficient coolant to balance liquid volume across multiple rear doors.
·Absorbs flow fluctuations caused by simultaneous water demand from multiple cabinets, ensuring stable coolant supplyto each cabinet.
·Absorbs flow fluctuations caused by simultaneous water demand from multiple cabinets, ensuring stable coolant supplyto each cabinet.
·Balances system pressure to prevent sudden pressure drops caused by insufficient chiler supply.
Dry Cooler
·Cools the hot water discharged from servers through air convection, dissipatingheat to the outdoors to complete heat exchange.
·Requires no water consumption, suitable for water-scarce areas, and avoids watelconsumption and scale issues assocated with traditional coolina towers.
·Stabilizes the temperature of the primary-side coolant, supplving low-temperatureliquid for subsequent cycles to ensure system heat dissipation efficiency.

Refrigeration Module
·Precise Temperature Control: liguid cooling chillers precisely control water temperature and fow to ensure equipmenttemperature remains within the optimal range at all times.
·Eneray Saving & Consumption Reduction: The liguid cooling system reduces significant power consumption required foair cooling, delivering higher cooling efficiency compared to traditional cooling methods.
·High -Density Deployment: As high-density Al applications expand, traditional air cooling solutions fail to meet heat dissipation demands, High-efficiency chillers support efficient heat exchange.
