Detailed Introduction to the Selection and Use of Heat Dissipating Fans

For non-professionals to choose cooling fans, we must confirm the following parameters. (Professionals can directly choose the model parameters they need.)

1. Fan size: length, width and thickness. Taiwan's three giant conventional sizes are 280 x 280 x 80 mm, 225 x 225 x 80 mm, 220 x 60 mm, 200 x 200 x 60 mm, 180 x 180 x 60 mm, 172 x 51 mm, 172 x 150 x 55 mm, 172 x 150 x 51 mm, 150 x 150 x 51 mm, 150 x 38 mm, 135 x 135 x 38 mm, 120 x 120 x 38 mm (25), 110 x 110 x 110 x 2 5 mm, 92 x 38 mm (25), 80 x 80 x 80 mm (30 x 60 mm).

2. Fan Voltage: AC 110V 220V 380V; DC 5V, 12V, 24V, 48V; If you have special voltage requirements, please specify that Taiwanese Three Giants will customize for you.

3. Fan bearings: oil bearing and double ball bearing. Difference: Life is different; theoretical life of oil bearing is about 30,000 hours, theoretical life of ball bearing is about 50,000 hours, and the price of ball bearing is more expensive than oil bearing.

4. Fan speed: General fan speed is divided into three specifications: high, middle and low. The higher the speed, the larger the air volume, the greater the static pressure, the greater the noise, the greater the current and power, and vice versa.

5. Fan interface: dividing lead and inserting terminal. It is necessary to confirm which interface to choose, and if it is a lead, it is necessary to specify the length of the lead. Generally, the default length is 30cm without special explanation.

6. Fan Certification: Are there any environmental requirements and need relevant certification? If necessary, specify before purchasing.

7. Fan accessories: Whether to match the mesh; mesh is iron mesh, plastic monolithic mesh, plastic triad mesh, or filter mesh group.
