Heat dissipation fans are widely used in all walks of life. However, we don't know how to purchase a batch of suitable heat dissipation fans for the company. Before purchasing heat dissipation fans, we need to know some parameters and required functions to better combine our own equipment and improve production efficiency.

1. Types of cooling fans: generally, cooling fans are divided into DC fans, AC fans, EC fans, cross flow fans, etc., which are selected according to their own product requirements.

2. Main parameters of the cooling fan: size, voltage, current, power, air volume, static pressure, noise, life, bearing system (double ball bearing, hydraulic bearing, oil bearing). These parameters are directly related to the cooling performance of the cooling fan, whether it is energy-saving, long life, and quiet.

3. Functions of the cooling fan: soft start function, locking protection function, overvoltage protection, FG speed measurement function, RD alarm function, TC temperature control function, PWM speed regulation function, waterproof function (waterproof function can be selected for outdoor, humid, dusty and other places under bad environment, and the waterproof grade gradually increases from IP54 to IP68) are all customizable functions.

4. Certification of cooling fan: UL, CE, ROHS, FCC, etc. (You can choose what certification is required according to your equipment positioning)

5. Power line of cooling fan: the wiring sequence, length, terminals, etc. shall be clearly combined with their own equipment.

Finally, I hope this explanation can help some buyers. If you want to purchase cost-effective cooling fans, just look for Yi Rongchuan. Yi Rongchuan focuses on R&D and production of various types of DC fans, AC fans, support fans, EC fans, booster fans, waterproof/dust-proof fans, DC blowers, etc. Factory direct sales, affordable prices, after-sales security, welcome to consult online.
