9HV DC Fans for Industrial Use
The 9HV series features high static pressure, high-speed, and long-life DC axial fans. Emphasizing a "compact size, high air pressure, and powerful cooling" design philosophy, these fans are widely deployed in high-thermal-resistance and high-reliability environments—such as those found in motorsports, industrial machinery, new energy systems, and server infrastructure.
I. Motorsports Application Case Studies
Engine Bay Cooling (GT / Rally Racing)
Scenario: During full-speed track driving, engine and/or turbo temperatures exceed 120°C; stock fans lack sufficient static pressure, leading to airflow blockage within the radiator core.
Solution: Two to three 9HV fans are connected in parallel to blow directly onto the radiator core. Their 1100 Pa static pressure is capable of penetrating high-density radiator fins, while PWM control allows for variable speed adjustment (60%–100%) based on coolant temperature.
Results: Coolant temperature stabilizes between 85°C and 95°C; turbo intake air temperature drops by 8°C to 12°C; horsepower increases by 3% to 5%; and the system operates fault-free throughout continuous 24-hour endurance races.
Electric Racing Battery / Motor Cooling (FE / EV Conversions)
Scenario: The electric motor generates peak power exceeding 200 kW, and the battery pack undergoes discharge currents exceeding 500 A; the enclosed compartment features high airflow resistance.
Solution: A 9HV fan is installed in series with the liquid-cooling radiator; its 1000 Pa static pressure effectively overcomes the flow resistance of the liquid-cooling plate. Additionally, a cluster of smaller 9HV fans is positioned alongside the battery pack to ensure temperature uniformity among individual battery cells, keeping the temperature differential below 2°C.
Forced Cooling for Braking Systems (Track Days / Drifting)
Scenario: Following continuous heavy braking, brake disc temperatures exceed 600°C, resulting in significant brake fade (thermal degradation).
Solution: A lightweight 9HV fan is mounted within the brake duct assembly to blow directly onto the brake disc and caliper. Its 2300 Pa static pressure allows airflow to penetrate the narrow gaps between the brake pads and disc, and—when combined with the air duct—significantly enhances cooling efficiency.
Results: Brake temperatures drop by 150°C to 200°C; the system prevents thermal fade during 10 consecutive laps of heavy braking; and brake pad lifespan is extended by over 30%.
