With the continuous development and progress of science and technology, in electronic products, cooling fans use forced convection to dissipate heat. Due to its own shunt function, the air can be cooled at a certain speed. By realizing the heat exchange between the air and the radiator, the heat dissipation effect can be achieved. Automobile cooling fans are also used in automobile installations. Generally, the correct automobile cooling fans are beneficial to better exert the heat dissipation performance of automobile engines and prevent malfunctions. Do you know how to install a car cooling fan? Let's take a look together.
Installation method of car cooling fan:
1. When installing the car cooling fan, there should 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 the 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-sided flange surface (single-side flange installation), and the installation adopts through bolts (on both sides of flange installation). When installing both sides of the flange, please fix the shell so that it does not change.
The reason why the fan blades of the cooling fan are singular
The motor cooling fan is generally not used alone, and will be used together with the radiator. It consists of motor, bearing, blade, shell (including fixing hole), power plug and wire.
This is mainly because in order to maintain the running balance of the cooling fan and minimize the influence of resonance, a single blade is the best choice, and it is difficult to achieve a symmetric point balance of the double blade in the mold. So for cooling fans, it is not a good thing to be in pairs.
The motor is the core of the cooling fan, which is generally composed of a stator and a rotor.
In the selection of the cooling fan fan, we often compare the air pressure and air volume. During 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, that is, air pressure.
Wind pressure is an important indicator to measure the performance of a cooling fan. The wind pressure mainly depends on the shape, area, height and speed of the fan blades. The faster the speed, the larger the fan blades. The higher the wind pressure, the radiator with the air duct design can better maintain the wind pressure of the fan.
I believe that after the above introduction, everyone has an understanding of the installation method of the car cooling fan and the reason why the fan blades of the cooling fan are singular. If you have any questions, please go to Ruiapple for consultation.
