The cooling fan includes a booster fan, also called a linear fan, so it is also called a linear fan, named after the fan, that is, the wind blows out in a straight line. The following is a detailed description of the supercharger fan and common cooling fan by the cooling fan manufacturer.
The cooling fan is also a linear fan. As the name suggests, this is a straight line of wind. It changes the wind direction through a turbine-shaped decentralized frame and multi-watts. The thorns are curved. After software design and simulation, the fan blows into a spiral shape to achieve a straight line direction. It is characterized by high negative pressure. It blows far, but the noise and power are higher.
The cooling fan is a conventional fan, usually with less than three or four loose frames. The wind blows into a trumpet shape, and everyone knows what shape a horn is! I will not say much here. It is characterized by the same model, low noise and low power at the same speed. The disadvantage is that the wind will not blow far.
When choosing a cooling fan, the size and design structure of the product must be considered. If the heating element is far away, try to consider using a linear cooling fan (supercharged cooling fan).
Then, the cooling fan manufacturers discuss how to choose this cooling fan for the ventilator.
1. Choose 8025, 9225, 12025 and 12038 models on common ventilator.
2. There are two power supply voltages, DC5V and DC 12V.
3. As mentioned above, it needs to be quiet, and the fan noise is very small, almost controlled at about 35 decibels.
4. The fan on the front of the ventilator must have a spherical structure and have a long service life.
5. For wide voltage fans, we usually use DC5V and DC12V voltages. DC12V voltage, we can switch to DC 18V.
6. Wide current chip design.
7. The material must be fireproof and environmentally friendly.
8. The fan must be balanced and handled correctly. If handled improperly, resonance will occur.
The cooling fan that can meet the above requirements can be used safely.
I believe that after the above introduction, everyone has an understanding of the issues that should be considered when buying a cooling fan. If you have any questions, please consult Ruiapple.
