Professional manufacturing and production of radiator cooling fans, condenser fans and fan motors, etc.

Is automotive cooling fan tested before shipment?

Yes, automotive cooling fan is fully tested before shipment. Tongchi Auto Air Conditioner Manufacturing Co., Ltd is a quality-oriented manufacturer with great achievements in quality control. Before we tapped into the global markets, we paid less attention to the ex-factory inspection, which results in the high rejection rate of the product. Now, since we have conducted detailed quality assurance rules and set up criteria for ex-factory product quality, the pass rate of the product has increased remarkably. Customers can rest assured about the product quality by remotely reviewing our QC process.

Many of our low-demand customers often go to the electronics market or the so-called wholesale department to buy cooling fans.

Automobile radiator fan factory is a cooling fan manufacturer integrating Ru0026D, production and sales.
Recently, we dealt with a case of changing the installation method of the cooling fan, which has a great impact on the cooling fan.

During normal use of any electronic product, due to the effect of current, there will be varying degrees of temperature rise inside the device, and when the temperature rise of the device exceeds a certain range, its life will be attenuated to varying degrees (for a long time, The safety of equipment operation will also be reduced).
Car cooling fan working position and its principle: cooling fan working principle 1.

The comprehensive laboratory of the automobile radiator fan factory has introduced new equipment-the thermal shock test box.
The commonly used cooling fan voltage is generally 12V, but some customers' products, such as temperature-controlled cooling fans, set a lower voltage for the cooling fan at low temperatures.
When we choose a cooling fan, especially for certain voltages that are not very stable or have several different voltage gears for speed adjustment, we need to understand the voltage range of the cooling fan, such as a cooling fan that works with a 12V DC voltage.
