How to design dust-proof cooling fans?
Jan 11 , 2022
The characteristics of the cooling fan itself are different from other products. Brushless cooling fan actively stirs the air and accelerates the airflow, so it also sucks in dust. There are two main aspects of inhaling dust. One is sucked into the bearing and the other is sucked into the rotor and stator. Inhalation of dust more or less affects the cooling fan, causing the fan to slow down and ev...

If the positive and negative poles are reversed, will the cooling fan burn out?
Jan 18 , 2022
DC cooling fan has two positive and negative power lines. When installing the cooling fan, if the positive and negative lines are connected reversely by wrong operation, will the cooling fan burn out? Whether the axial cooling fan is burnt out or not is mainly related to the IC Design of the cooling fan. In general, the drive IC with double wire winding method has internal protection design. If th...

How to choose the cabinet cooling fan?
Jan 26 , 2022
1. When purchasing cabinet cooling fans, first confirm the size of the cabinet, select the appropriate fan model and appearance for installation, and then determine the parameters such as voltage, airflow, speed, current, noise and other parameters. 2. Cooling fan voltage, which can be divided into DC voltage 5v, 12v, 24v and 48V; AC voltage 110V, 220v, 380v. If the wrong voltage is connected, the...

Where is the cooling fan used?
Feb 23 , 2022
Cooling fans, as the name suggests, are used for ventilation and heat dissipation. It is widely used in various industries and fields, because in many electronic equipment and machinery, if there is no cooling device installed in the equipment, the working temperature may be too high, which may cause the performance of the equipment to decline, or even be damaged. For normal and efficient operatio...

Why the speed of DC cooling fan slows down?
Mar 26 , 2022
Why the speed of DC cooling fan slows down? The speed of the cooling fan is determined by voltage, fan blade angle, diameter, number of fan blades, bearings, etc. So what is the reason why the cooling fan slows down? The speed of the cooling fan is mainly determined by the structure and components of the fan itself, the bearing friction and the wind resistance of the inclination angle of the fan b...

What are the anti-corrosion measures for industrial cooling fans?
Sep 09 , 2022
The production of industrial equipment is inseparable from the accessories industrial cooling fan. The main function of the fan is to dissipate heat, cool and remove dust for various sizes of equipment. The general production environment of industrial equipment is relatively harsh. In order not to shorten the service life of the industrial cooling fan, some treatment will be done for the fan. The ...

What factors will affect the air volume of the cooling fan?
Oct 21 , 2022
Air volume refers to the total volume of air discharged or incorporated by the cooling fan per minute. If it is calculated in cubic feet, the unit of air volume is CFM. In cubic meters, that's CMM. The air volume unit often used by cooling fans is CFM. Air volume is the most important indicator to measure the heat dissipation capability of heat dissipation fans. Obviously, the greater the air volu...
