At present, there are many people who do not understand the cooling fan in the purchase, often fall into the misconceptions of the industry selection, obviously a penny a penny, they spend a large price but it is difficult to buy the right cooling fan, then you must have fallen into the industry misconceptions. If you want to pick the right or even value for money cooling fan, you must first understand the industry, understand the product, and then see how we pick the cooling fan. Now YCCFAN cooling fan manufacturer to tell you what we need to pay attention to when picking cooling air. First of all, many people will think that domestic products can not do as foreign cooling fans to eliminate static electricity

What we can do is to prevent and safely use the product, so that the product can maintain the best condition and reduce the natural loss of the product, if it is used improperly, the life of the cooling fan will naturally be shortened or even damage to it, so the daily care, use and maintenance has become a point of concern. So after buying a cooling fan, how should we use and maintain it? 1, when the cooling fan in operation, do not let the cooling fan fan blades locked for too long, which will produce high heat loss or even directly burn

DC cooling fan is an important heat dissipation device in modern industry, which is widely used for its simple structure, easy installation, good heat dissipation, long service life and other characteristics. So what is the structure and principle of DC cooling fan, and how to buy it and how to install it? DC cooling fan main structure and principle: DC cooling fan mainly consists of motor rotor, stator, fan blade and other auxiliary components combined, there are many semiconductor components in the control circuit, today's technology has been able to put multiple semiconductor components in one or more IC, there are many manufacturers will be specially designed A variety of models of control motors

Cooling fans can be divided into two main categories: AC cooling fans and DC cooling fans. And mainly used in computer equipment, household appliances, automotive equipment, mechanical equipment and other fields for its ventilation and heat dissipation. Among them, AC cooling fans are 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 devices. In addition to these, let's look at the main differences between AC cooling fans and DC cooling fans. 1, AC / DC cooling fan operating principle (1), the principle of DC cooling fan operation is based on the amperage determination
