The cooling fan can be divided into two categories from the power supply mode: AC cooling fan and DC cooling fan. It is mainly used for ventilation and heat dissipation in computer equipment, household appliances, automotive equipment, mechanical equipment and other fields. The AC cooling fan is mainly used in industrial machinery and equipment, medical equipment and other large equipment; Dc cooling fans are generally used in computer electronics, household appliances and other small equipment. In addition to these, let's look at the main differences between AC cooling fans and DC cooling fans.

What is a brushless cooling fan motor?

The brushless DC cooling fan motor is composed of a motor body and a driver, and is a typical mechatronic product. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as the commutatorless motor. As early as when the motor was born in the last century, the practical motor produced was a brushless form, that is, an AC squirrel cage asynchronous motor, which was widely used. However, asynchronous motors have many insurmountable defects, so that the development of motor technology is slow. Transistors were born in the middle of this century, so a brushless DC cooling fan motor that uses transistor commutation circuits instead of brushes and commutators came into being. 

DC cooling fan is an important cooling device in modern industry, which is widely used because of its simple structure, easy installation, good heat dissipation effect and long service life. So what is the structure and principle of DC cooling fan, and how to buy and install it reasonably?

The concept of air volume is relatively easy to understand, refers to the volume flow per unit time, the simplest way to calculate is Q=vA, v is the fluid speed, A is the area of flow. The unit of air volume in the cooling fan is usually...

On the introduction of cooling fan air volume and wind pressure, the Internet has long been a search of a large number, is also a commonplace problem, but in the circle can make this problem clear really is very few...
