Introduction of New Products Launched in 2024
Open Loop Direct Liquid Cooling Module
Sunon’s Open-Loop Direct Liquid Cooling Module is designed for the dual-core Intel Eagle Stream (socket LGA 4677) platform, effectively enhancing cooling performance in server systems. To meet the evolving needs of data centers, Sunon provides customizable AI x HPC liquid-cooling design services, tailoring solutions based on cooling configurations and server density. With its compact size and high integration capability, this liquid-cooling module ensures superior thermal performance, high TPU efficiency, and exceptional reliability for next-generation server infrastructures.
Self-Circulated Phase Change Liquid-Cooling Technology
Sunon’s self-circulated phase-change liquid cooling technology leverages pressure and density differences created during phase transitions to generate fluid convection. This allows heat generated by CPUs, GPUs, and DCUs to be efficiently transferred vertically to the radiator. A high-efficiency cooling fan then rapidly cools the high-temperature liquid, condenses the vapor back into liquid form, and circulates it back to the starting point—all without the need for a water pump. This innovative pump-free system enhances reliability, serviceability, and energy efficiency while significantly reducing costs, noise, and vibration, making it an ideal solution for high-performance AI workstations.
Air-Assisted Liquid-Cooling Server Sidecars
Sunon’s Air-Assisted Liquid-Cooling (AALC) server sidecar integrates air-cooling and liquid-cooling technologies, featuring a direct liquid-cooling unit, heat rejection unit (HRU), fan wall, and reservoir and pumping unit (RPU). AALC rapidly transfers heat from CPUs and GPUs via cold plates to the hot side of the system. The heated liquid is then directed through rack manifolds or pipelines to the RPU beneath the hot side. Inside the RPU, a high-performance water pump drives the liquid through the cooling waterway near the HRU and fan wall for forced cooling. Once cooled, the liquid is recirculated back to the cold plates on CPUs and GPUs via manifolds or pipelines, ensuring a fast and efficient cooling cycle. Sunon’s AALC solution delivers top-tier thermal performance, with a Thermal Design Power (TDP) of 60 to 80 kW, making it ideal for high-performance computing (HPC), supercomputing, generative AI, and other compute-intensive applications.
2M Energy-Saving Large Industrial Wall-Mounted Fan
Sunon’s Energy-Saving Large Industrial Wall-Mounted Fan is a fixed-directional fan designed specifically for factories with limited floor space or insufficient ceiling height. Its flexible installation options allow users to mount it wherever needed, ensuring precise cooling and ventilation for specific areas. With its large 2-meter blades, the airflow can reach up to 36 meters—equivalent to one-third the length of a football field. Equipped with a BLDC motor, this fan delivers outstanding energy efficiency, powerful airflow, and quiet operation, making it the ideal ventilation solution for crowded workspaces.
