The cross-flow cooling fan is characterised as a cross-flow fan that can be used for localised ventilation, is very easy to install, provides significant ventilation and is safe. In addition, crossflow cooling fans can be used in the aerospace industry as an alternative to conventional fans for propulsion systems. They are characterised by their ability to be embedded in the wing, which effectively reduces the drag of the propulsion system and enhances the lift coefficient.

Cross-flow cooling fans are used in a wide range of applications, including industrial cooling, aerospace industry, cooling equipment, dry-type transformer cooling capacity increase. In industrial heat dissipation, cross-flow cooling fan is mainly applied to the large surface of cooling equipment, such as cross-flow fan, whose inlet and outlet air are perpendicular to the axis, and which consists of three parts: impeller, air duct and motor. In the aerospace industry, cross-flow cooling fans can be embedded into the interior of the wing to reduce the drag of the propulsion system and increase the lift coefficient. In cooling equipment, cross-flow cooling fans are mainly used for dry-type transformer cooling to increase capacity, which can increase the capacity by 40"50% operation, ensure the normal operation of the transformer and extend its service life.

Cross-flow cooling fans are also used in a wide range of motor designs and applications, including air purifiers, wine coolers and other equipment. For example, the cross-flow cooling fan provided by Ningbo Langwei Electric Technology adopts high-quality aluminium alloy multi-wing fan blades, which are strictly calibrated for dynamic balance, and has the advantages of light weight, low noise, low vibration, large air volume, and is not easy to corrode and rust.

Overall, cross-flow cooling fan has the characteristics of simple structure, small volume, high dynamic pressure coefficient, low noise, large air volume, smooth operation, easy installation, etc. It is widely used in industrial cooling, aviation industry, cooling equipment, dry-type transformer cooling capacity increase and other fields.
