Rack Level Liquid-Liquid Cooling Solution

Heat Exchange Capacity: 50kW, 80kW

Overviews

A compact, cabinet-based liquid-liquid cooling system, designed for small-scale or distributed liquid cooling scenarios (2+ liquid cooling cabinets). It uses dual liquid circuits (primary: cooling water; secondary: 25% ethylene glycol) for heat exchange, with 50kW-80kW cooling capacity and supports 19/21-inch standard racks.
Key CDU components (sensors, pumps) adopt redundant designs; it features small size, no major room modification, and easy expansion by single cabinet. Ideal for small-medium data centers, space-constrained edge computing facilities, and cold-plate liquid cooling scenarios needing flexible capacity increase.

Application Scenarios

Small and medium-sized data centers, suitable for small-scale or distributed deployment of liquid-cooled computing scenarios (applicable to 2+ liquid cooling racks or above).

Edge computing facilities in space-constrained environments that require high-performance liquid cooling for edge computing.

Cold plate liquid-cooled computing application scenarios requiring flexible expansion, allowing capacity increase with a single rack as the minimum unit.

Product Features

Multi-Scenario Compatibility: Available in two size specifications (19-inch and 21-inch) to adapt to different application scenarios.

High Heat Density Deployment: The standard rack supports a power density ranging from 50kW to 200kW.

High Redundancy Design: Key components of the CDU (e.g., sensors, pumps) adopt redundant designs to maximize operational safety.
