Cross Flow Fans, also known as tangential or tangential flow fans, are specialized air-moving devices designed for various applications requiring uniform airflow across a wide area. They utilize a unique impeller design to produce airflow perpendicular to the fan’s axis, making them suitable for applications with limited space constraints.

1.Product Features:

  • Cross Flow Impeller Design:

Features a cylindrical or tubular impeller with curved blades that generate airflow perpendicular to the fan’s axis, creating a wide and uniform airflow pattern across the length of the impeller.

  • Compact Size:

Space-saving design allows for installation in tight spaces or applications with limited clearance, making them suitable for use in compact electronic devices, appliances, and equipment.

  • Uniform Airflow Distribution:

Provides uniform airflow distribution across the entire length of the impeller, making them ideal for applications requiring even cooling, heating, or air circulation.

  • Low Noise Operation:

Engineered for quiet operation, making them suitable for noise-sensitive environments such as residential, commercial, and medical settings.

  • Directional Control:

Allows for flexible airflow direction control by adjusting the orientation of the fan, providing versatility in meeting specific application requirements.

2.Application Scenarios:

  • Electronics Cooling:

Ideal for cooling electronics and electrical components in devices and equipment such as refrigerators, air conditioners, ovens, heaters, and electronic enclosures.

  • HVAC Systems:

Suitable for use in heating, ventilation, and air conditioning systems to provide supplemental air circulation and optimize indoor air quality.

  • Automotive Applications:

Employed in automotive HVAC systems for cabin ventilation, defrosting, and heating, providing uniform airflow distribution across the vehicle interior.

  • Appliance Cooling:

Utilized in household appliances such as clothes dryers, dishwashers, and microwave ovens for cooling and ventilation purposes.
