Customized high-reliability fan systems for data centers,5G base stations and other heat dissipation needs. The axial fan for server cabinets adopts redundant design and supports N+1 backup to ensure 24-hour uninterrupted operation; the waterproof and dustproof centrifugal fan for base stations reaches IP65 protection level and works stably in a wide temperature range from - 40℃ to 70℃. The innovatively developed heat pipe coupled cooling fan controls the CPU temperature below 65℃ through phase change heat transfer technology. The innovatively developed heat pipe coupled cooling fan controls the CPU temperature below 65℃ through phase change heat transfer technology,which is applied to edge computing equipment and blockchain miners to ensure that the PUE value of the data center is lower than 1.3.
