Data Centre Liquid Cooling (Air & Liquid series)CDU
PRODUCT DETAIL
Air-liquid collaborative CDU of HEEALARX Data centre liquid cooling system: A rack-level hybrid cooling solution for high-density computing.Seamlessly fits standard 19-inch server racks, enabling quick deployment of high-power servers with no major retrofits to existing data center infrastructure.This integrated air-liquid cooling control unit delivers stable, efficient thermal management, ensuring low PUE and reliable operation for modern high-density computing environments.
Coolant Preparation & Delivery
The CDU(Coolant Distribution Unit) cools the coolantfo the set temperature (typically 20-30°C)viaits internal heat exchanger. Powered by thewater pump,the low-temperature coolant isdelivered to each server through dedicated pipelines.
Air&Liquid CDU
·Integrates circulation pumps, fans, heat exchangers, and other core parts to provide an independent air-liquid collaborative coolindsystem forieauipment
·Coolant absorbs heat from the equipment and is cooled by the heat exchanger through air cooling before recirculating, ensuringhigh-efficiency heat dissipation.
·Suitable for computer room upgrades, laboratories, and other scenarios. Features fiexible deployment and convenient operation & maintenance.

Liquid-Cooled Door
·Cabinet-Level Air-liauid Conversion: Uparade the liauid-cooled door to the main heat exchanger of the Air-liguid Cou, directhutilizing the cold air in the computer room for coolant circulation, achieving full heat capture of 30kW per cabinet.
·Passive Air-Liauid Heat Exchange: As the heat exchanae terminal of the CDU, it passivly uses the air flow in the computer room forcooling, enabling near-zero eneray consumption free cooling, sianificantly reducing PUE and noise.
·Integrated Thermal Management: As theexchanger of the CDU.it achieveszero heat leakage in the cabinet, supportsmixed deployment of air-cooled and iquid-cooled servers, and is compatible with GPU server upgrades in existing computer rooms.
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.
