With the progress of the times and the rapid development of the electronic industry, the equipment cooling and cooling system is becoming more and more severe. The rise of the cooling fan industry is also an inevitable trend. DC cooling fans have become an indispensable part of electrical machinery. Today, DC fans on the market are There are more and more brand products, and there are more and more manufacturers, but at the same time, there are also poor quality products, which makes people worry. Let me discuss the ordering standards of DC cooling fans with you, and solve the problem for everyone. :

Standard 1: "Brand" Generally, we will choose branded products, not because of how good the branded products are, but because good brands are the guarantee of product quality, because they have their own credibility and are worth relying on. It is also a guarantee for consumers.

Standard 2: The DC cooling fan products produced by all businesses in "Bearing" are divided into two major bearings. 1, Ball bearing. 2, Oil bearing. Ball bearing features: long life, low noise, oil bearing features: cheap.

Criterion 3: "Performance" start-up test, touch it with your hand, feel its vibration amplitude, garbage-level products generally have a large vibration amplitude and are extremely irregular. Moreover, the temperature of the axis will gradually increase, and the abnormal sound will be loud.

Standard 4: "Noise" The size of the noise is also one of the factors that determine the quality of the product. When the size of the DC fan is the same and the voltage is the same, the greater the noise, the worse the quality.

The above is the ordering standard for DC cooling fans. The brand merchants professionally develop DC/AC/supercharger/support fans, which are trustworthy.

Car fan model classification:

Car fans are mainly used to cool the car water tank. All cars now use water-cooled + air-cooled designs. When the temperature of the water tank is too high, the fan will automatically turn on and use the principle of air flow to dissipate heat to the water tank to prevent the engine temperature from being too high. The other is the luxury type, which is generally composed of two small fans. The luxury car fan heats the water tank and the air conditioning box is in front of the water tank. The fan work to drive the air flow helps to reduce the water temperature, but the water temperature is not as low as possible, and the engine temperature is too low.

Car fan purchase tips:

When you are purchasing this product, you need to select the type of car fan blades according to the conditions of the head space and the heat dissipation of the engine, determine the wind speed, and the outer diameter of the fan, and then make a selection.

Next, you need to calculate the performance curves of similar fans according to the fan similarity theory, so as to determine the regional matching points of the fans and the system, and then calculate the fan efficiency of the corresponding matching points. Of course, there are certain methods for car fan selection. , and experiments show that in general, the lowest point of noise corresponds to the highest point of efficiency.

Finally, the specifications and parameters of the cooling fan are determined according to the model and space. At the same time, cooperate with the technicians of the car fan manufacturer to design the fan performance and style most suitable for the car itself. The above are some tips for car fan purchase, I hope to help you, and if you want to know more about car fans or adopt a lot of car fans, you can pay attention to our company "Jingxin Technology (Huizhou) Co., Ltd. company".
