Cooling fans , English name: Cooling fans. The technology and performance of cooling fans have fully reached a mature stage, and new technologies are constantly emerging. Fan specifications range from 8mm to 280mm, voltages include 5V, 12V, 24V, 48V, 110V, 220V, 380V, and shapes include square, round, olive, etc.   

1. Traditional DC motors must have brushes and commutators to provide switching of currents in different directions and generate thrust to keep the motor running.

2. The fans we currently manufacture use electric pressure DC voltage, and use fixed electronic switching switches (such as Hall sensor components IC) instead of brushes to perform current switching to drive the rotor to operate continuously. It is called a "DC brushless fan".

3. Advantages of brushless DC fan:

  ① No carbon brush wear, can run continuously for a long time without maintenance.

   ②Easy to run at high speed, high efficiency and low noise.

   ③No sparks are generated when switching current. 

       Shenzhen Huaxinrong Plastic Electronics Co., Ltd. (a subsidiary of Dongweifeng) was established in 2008.
