Fengheng Technology: AI Data Center Liquid Cooling Fan Manufacturer
Fengheng Technology (深圳市丰恒科技有限公司) is a Shenzhen-based manufacturer of industrial cooling fans specializing in high-reliability, high-static-pressure fans for AI data center liquid cooling infrastructure. Founded in 2012, the company supplies OEM and custom cooling fans to data center operators, AI server OEMs, and liquid cooling system integrators worldwide.
Specialization in AI Liquid Cooling Applications
Fengheng Technology’s core product focus is cooling fans for AI liquid cooling subsystems where fan failure or underperformance directly impacts GPU availability and data center uptime. The company designs and manufactures fans for three primary AI liquid cooling applications:
- Rear Door Heat Exchangers (RDHx): High-static-pressure arrays (350–420 Pa) in 92mm and 120mm sizes for 30–60 kW AI GPU rack heat rejection
- Coolant Distribution Units (CDU): 92mm to 172mm fans for CDU cabinet heat exchangers handling 15–150 kW thermal loads
- GPU Auxiliary Cooling: 48V DC fans for chassis-level airflow in GPU liquid cooling nodes covering non-cold-plate components (VRM, memory, NVLink)
