How to choose fan for electric cabinet?

Electric cabinet fans can blow cold air into the cabinet to regulate the temperature of electronic equipment. By generating a slight overpressure, they can prevent dust from entering the cabinet.

Usually, these fans are installed on the doors or side walls of the cabinet and integrated into the ventilation grid. There are also some models that can be installed on the top of the cabinet. They are equipped with filters to prevent dust from entering the electrical cabinet.

The selection basis of this fan is:

1. Air Displacement

2. Cabinet power supply voltage

3. The effectiveness of the filter

Why choose spiral fan?

A spiral fan (or axial fan) is composed of a propeller whose engine rotates on its shaft. The propeller pushes the air flow parallel to its axis of rotation.

The spiral fan can provide high air flow, but the pressure between the upstream and downstream has hardly increased. Due to the low overpressure, their use is limited to short circuits caused by low pressure drops.

Axial fans usually have 2 to 60 blades. Its efficiency is 40% to 90%.

Such fans are generally used for air circulation in large rooms, through-wall ventilation and duct ventilation in rooms.

Compared with centrifugal fans, spiral fans occupy less space, lower cost and lower noise.
