The performance of heat dissipation fan is related to the overall heat dissipation level of the electrical appliances used. Its function is very important. Nowadays, heat dissipation fan is widely used, ranging from small electronic products to refrigerator cabinets. It is necessary to use heat dissipation fan to ensure that product temperature is controlled in a controllable range and prolong service life. The market of heat dissipation fans is large, and the competition among heat dissipation fans manufacturers is fierce. Different manufacturers have different models and functions of heat dissipation fans. Consumers have some headaches when choosing and purchasing heat dissipation fans. They don't know which one to choose. Therefore, it is particularly necessary to choose efficient heat dissipation fans.

When choosing and purchasing cooling fans, we should focus on the following performance and indicators of fans.

1. Power of Fan

Generally speaking, the higher the power of the cooling fan, the stronger the wind will naturally be and the better the cooling effect will be. But we do not choose the heat dissipation fan to say that the greater the power, the better. We need to combine the material and working principle of the fan to make a comprehensive comparison. Also according to the actual use of the choice, high-power radiation fans will naturally consume more energy, if not too strong radiation effect, can choose a relatively small power.

2. Fan Speed

The speed of the cooling fan is the same as the power. The speed of the cooling fan also determines the size of the cooling fan. Of course, if the fan's speed is greater, the noise and vibration will certainly be greater, so when the air volume is enough to heat the product, try to choose a low speed fan.

3. Material of Fan

Generally, there are two main materials of heat dissipation fans on the market: plastic and aluminium. Generally, the material of DC heat dissipation fan is plastic, while the aluminium fan is AC fan. The heat dissipation effect of AC fan is lower than that of DC fan, and the air volume is smaller.

4. Noise of Fans

The noise problem of heat dissipation fans is not too big or too small, and the general users will not care much about it. However, many heat dissipation fans with poor quality will produce great noise due to bearing wear or other reasons after using for a period of time, which will not only affect the service life of fans, but also make people upset. Therefore, consumers are advised to choose strong manufacturers to purchase heat dissipation fans to ensure quality.
