The performance of an electronic cooling fan is related to the overall heat dissipation level of the electrical appliances used, and its function is very important. Nowadays, cooling fans are widely used, ranging from electronic products to refrigerator cabinets, electronic cooling fans are needed to ensure that the product temperature is controlled in a controllable range to prolong the service life.
The market for DC cooling fans is large, and there is fierce competition among cooling fan manufacturers. Different manufacturers have different cooling fan models and functions. Consumers will inevitably have a headache when buying cooling fans and do not know which one to choose. Therefore, it is particularly necessary to choose an efficient dc cooling fan.
When purchasing a DC cooling fan, we should focus on the following performance and indicators of the fan:
Generally speaking, the higher the power of the cooling fan is, and the stronger the wind is, the better the heat dissipation effect will be. But our choice of cooling fan does not mean that the power needs to be greater as much as possible, we need to combine the material and working principle of the dc cooling fans to make a comprehensive comparison.
It is also necessary to choose according to the actual use. High-power cooling fans consume more energy. If you don't need too strong cooling effect, you can choose a lower power.
The speed of the cooling fan is the same as the power, the bigger the better. The speed of the dc cooling fan is also a factor that determines the air volume of the cooling fan.
Of course, if the fan rotates faster, the noise and vibration will definitely be greater. Therefore, when the air volume is sufficient for the cooling conditions of the product, it is better to choose a low-speed dc cooling fan like a micro cooling fan as much as possible.
Generally, there are two main materials for cooling fans on the market: plastic and aluminum. The general material of the dc cooling fan is plastic, while the aluminum fan is an ac fan. The heat dissipation effect of the ac fan is lower than that of the dc cooling fan, and the air volume is small.
The noise problem of the cooling fan is neither big nor small, and the average user will not care much. However, many dc cooling fans of poor quality will produce a lot of noise due to bearing wear or other reasons after being used for a period of time, which will not only affect the service life of the fan, but also make people feel irritable. Therefore, it is recommended that consumers should choose a large manufacturer to purchase the cooling fan to ensure quality.
