Liquid cooling racks serve as the core terminal heat dissipation carrier for high-density computing scenarios. Developed to address the thermal bottlenecks of high-power computing hardware, they replace conventional air-cooled racks and deliver high-efficiency heat transfer via cold plate liquid cooling technology. The equipment is connected upstream to the Coolant Distribution Unit (CDU) and the facility chilled water system, and downstream to computing servers, acting as the fundamental building block for constructing an end-to-end liquid cooling thermal management system, and delivering a stable, efficient and secure thermal bearing solution for high-density computing clusters.
