With the continuous development and progress of science and technology, in electronic products, the cooling fan adopts forced convection heat dissipation.Because of its divergent function, the air can be cooled at a certain rate.By realizing the heat exchange between the air and the radiator, the heat dissipation effect can be achieved.The motor cooling fan is generally not used alone and will be used together with the radiator.It consists of a motor, a bearing, a blade, a housing (including a fixed hole), a power plug and a wire.
This is mainly because in order to maintain the operating balance of the cooling fan and minimize the impact of resonance, the single fan blade is the best choice, and it is difficult to achieve the symmetrical point balance of the double fan blade in the mold.So it's not a good thing for cooling fans to pair off.
The motor is the core of the cooling fan, which is generally composed of stator and rotor.
In the selection of cooling fan, we often compare the air pressure and air volume.In normal ventilation, the air pressure and air volume need to overcome the resistance in the ventilation stroke of the cooling fan.The cooling fan must generate pressure to overcome the air supply resistance, the air pressure.
Wind pressure is an important index to measure the performance of cooling fan.The wind pressure mainly depends on the shape, area, height and speed of the fan blades.The faster the speed, the bigger the fan blade.The larger the wind pressure is, the radiator with air duct design can better maintain the wind pressure of the fan.
In addition, the automobile cooling fan is also used in the automobile installation, generally correct automotive cooling fan is conducive to better play the heat dissipation performance of the automobile engine, to prevent the occurrence of failure.Do you know how to install a car cooling fan?Let's get to know it together.
Installation method of automotive cooling fan:
1. When installing the automobile cooling fan, there shall be no gap between the cooling fan and the panel.If there is a gap, it will affect the cooling effect of the fan.
2. The mounting hole of the cooling fan should be larger than the diameter of the fan, so that there is enough space to install the fan.
3. When inhaling on the side of the cooling fan, the operator should try to stay away from the cooling body.
4. The rapid change of wind direction and cross-sectional area of the fan will reduce the cooling effect. Please try to avoid this situation.
5. The installation adopts single-side flange surface (single-side flange installation), and the installation adopts through bolts (both sides of the flange installation).When installing both sides of the flange, please fix the shell so that it does not change.
