Why turn on the industrial fan to dissipate heat, but it has no effect? Why is the cooling effect of my industrial fan so poor? If you want to avoid the above problems, you need to pay attention to the following three points when purchasing industrial cooling fans.
1. Speed
The speed of the fan refers to the speed of rotation of the fan, which is usually measured by the number of rotations in one minute, that is, the RPM marked on the fan. The higher the RPM, the faster the fan speed and the better the cooling performance of the fan. However, it should also be noted that the greater the speed of the fan, the noise and vibration will increase accordingly. Suzhou Santian Precision Mould Manufacturing Co., Ltd. recommends that you choose a low-speed fan that meets the heat dissipation requirements when purchasing the fan.
If you don’t mind the noise and vibration, you should pay attention to whether the bearing of the fan is safe and can withstand the high-speed rotation of the fan when purchasing an industrial fan, so as to prevent the fan bearing from breaking at high speed, which is very dangerous!
2. Number of blades
The industrial fan rotates the blades to make the air flow, thereby generating wind and achieving the purpose of heat dissipation. The amount of air volume generated also has a certain relationship with the number of industrial fan blades. Generally speaking, it is best when the number of industrial fan blades is 3, and the air volume generated at this time is the largest. The 5-blade industrial fan on the market does not generate as much air as the 3-blade industrial fan, but the noise emitted is much smaller. Suzhou Santian Precision Mould Manufacturing Co., Ltd. recommends that you buy a three-blade industrial fan, and do not choose to buy an even-numbered industrial fan, because this does not meet the balance principle of rotational dynamics, and it is easy to cause blade collision and damage.
3. Air volume and pressure
The air volume and air pressure of an industrial fan refer to the speed of air flow and the resistance to air supply it can produce. The measurement of air volume and pressure requires professional tools, so we can generally only use the data provided by the manufacturer as a reference.
The unit of air volume is m³ / s. When the value is larger, it means that the air volume of the industrial fan is larger, then the air absorbs more heat, and the heat dissipation effect is more obvious.
Wind pressure is the most difficult to judge. Generally, manufacturers rarely write wind pressure on product data, which can only be experienced by the purchaser.
Suzhou Santian Precision Mould Manufacturing Co., Ltd. recommends that you can pay attention to these two data when purchasing industrial cooling fans. If not, you can ask the manufacturer. If the manufacturer does not know, you may try it yourself and make a decision. Don’t be deceived!
