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°C to 70°C. The innovatively developed heat pipe coupled cooling fan controls the CPU temperature below 65°C through phase change heat transfer technology. The innovatively developed heat pipe coupled cooling fan controls the CPU temperature below 65°C 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.
