As we all know,Cooling fanThe principle of operation is based on energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Its circuit principle is generally divided into a variety of ways, the use of different circuits, the function of the fan will be different.

cooling fan, english name: Cooling fans. The technology and function of the cooling fan has completely reached a mature stage, and new technologies are constantly emerging. The standard size of electric fans ranges from 8mm to 280mm, and the voltages are 5V,12V,24V,48V,110V,220V,380V. The shapes are square, round, olive, etc.

1. Fans can be classified into several types according to the materials used, such as iron shell fans (general fans), glass fiber reinforced plastic fans, plastic fans, aluminum fans, stainless steel fans, etc.

2. Fan classification can be divided into centrifugal, axial flow, diagonal flow (mixed flow) and cross flow type according to the direction of gas flow.

(1) centrifugal fan. After the airflow enters the impeller of the fan axially, it first flows along the radial direction. This kind of fan is made according to the principle of centrifugal action, and the products include centrifugal fan, centrifugal blower and centrifugal compressor.

(2) axial flow fan. The air flow enters the impeller of the fan axially and flows in the axial direction approximately on the cylindrical surface. Such fans include axial fans, axial blowers and axial compressors.

(3) Reverse fan. Rotation of the rotor is used to vary the plenum volume for work. Common types are Roots blowers and reverse compressors.

3. The fan is divided into axial flow fan, centrifugal fan and diagonal flow (mixed flow) fan according to the flow direction after entering the impeller.

4. Fans are divided into press-in partial fans (hereinafter referred to as press-in fans) and extraction partial fans (hereinafter referred to as extraction fans) in which flameproof motors are placed outside or inside the flow channels, and flameproof motors are placed in explosion-proof sealed cavities.

5. The fan can also be divided into single-stage, double-stage or multi-stage pressurized fans in accordance with the way of pressurization. For example, 4-72 is a single-stage pressurized fan, and the high-end fan is a multi-stage pressurized fan.

6. Fans can be divided into axial flow fans, mixed flow fans, roof fans, air conditioning fans, etc. according to their usefulness.

7. Fan pressing force can be divided into low pressure fan, medium pressure fan, high pressure fan.

8. According to the outlet pressure (boost) is divided into: fan (≤ 15000 Pa), blower (1.5~350000 Pa), compressor (≥ 350000 Pa).

Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings ventilation, dust and cooling; boilers and industrial furnaces ventilation and wind; air conditioning equipment and household appliances in the cooling and ventilation; grain drying and selection; wind tunnel wind source and hovercraft inflation and push.
