Automotive Low Voltage Electric Fan
Brushless electric fans for auxiliary cooling in new-energy commercial vehicles and traditional internal combustion engine (ICE) vehicles
Saiensi specializes in the R&D and manufacturing of automotive low voltage electric fans. With a CNAS-certified laboratory, an 80% in-house production rate, and rigorous control over materials, cost, delivery, and quality, the company produces electronic cooling fans engineered for both new energy commercial vehicles and conventional fuel vehicles. These fans, typically operating at 12V or 24V, are motor-driven and electronically controlled to adjust rotational speed, providing reliable cooling support for engines and air-conditioning systems.
- Conventional vehicles: Installed at the front of the engine compartment, working with the radiator or coolant tank to assist engine cooling.
- Battery pack cooling: Mounted within the battery system, integrating waterproof fans and liquid cooling for efficient heat dissipation.
- Drive motor cooling: Positioned near the motor housing or coolant channels to maintain stable motor temperatures.
- Power electronics cooling: Supports air or liquid cooling combinations to protect critical electronic components.
