Cooling fans are widely used in different industries, and the application requirements of each industry are inconsistent. Outdoor communication equipment needs waterproof fans, cabinets and driverless cars need large air volume fans, and the medical industry needs ultra-quiet and long-life fans. So what should we consider when selecting?

Today small make up for everyone popular science:

1. Dimensions
The size and size of the cooling fan should be selected according to the structural design of the equipment, and other parameters should be confirmed after the size is confirmed. Generally, the fan speed with small size will be higher.
2. Bearing
The bearings of the cooling fan are divided into double ball bearings, hydraulic bearings, and oil-containing bearings. The life and noise of the three bearings are from high to low.
3. Noise
The noise of the cooling fan, generally speaking, the smaller the noise, the better, the more sought after by users, but the size of the noise is directly related to the air volume, bearings, etc., we should combine the actual environment to select the type.
4. Air volume
The air volume of the cooling fan, the greater the air volume, the greater the wind, the better the heat dissipation performance of the fan, but the noise will also increase, and the service life of the fan will also be affected to a certain extent.
5, the signal
The signal line of the cooling fan is selected, and the signal line is one of our small helpers.
1. RD alarm signal is an alarm signal when the fan stops, which enables us to deal with and repair it in time.
2. FG speed measurement signal can detect the speed of the fan when it is running in real time.
3. PWM speed control signal, the speed control signal can adjust its speed according to the different climate of the four seasons, saving power consumption and reducing noise.
4. The temperature control signal can automatically adjust its speed according to the surrounding air temperature.
