Note: Customized products for other working conditions are available.
(1)High-power density datacenters: In scenarios such as high-performance computing (HPC), cloud computing, and Al training, the server density is relatively high, generating a huge amount of heat. The wind liquid CDU can quickly remove heat through liquid cooling technology, ensuring that the operating temperature of the equipment remains within a safe range.
(2)Prefabricated and modular data centers: In prefabricated or modular deployments, space is limited and thermal loads are concentrated. The compact design and efficient cooling capacity of the wind-liquid CDU make it an ideal choice.
(3)Green energy and energy-saving upgrades: As enterprises place greater emphasis on environmental protection and energy conservation, wind liquid CDU helps data centers achieve low-carbon operation goals by reducing power consumption and enhancing cooling efficiency.
(4)Applied to micro and space-constrained data centers: Modular design ADAPTS to heterogeneous computer room layouts, no infrastructure modification is required, and it supports rapid deployment beside racks.
