Tip: Using Axial fans in Celsius 3D

Axial fans are designed to displace a large volume of air and are therefore, suitable for low-pressure systems. These fans produce high turbulence, resulting in higher noise levels. The air flow in these fans is parallel to the axis of the fan.

To add an axial fan:

1. Choose Parts > Create Axial Fan.

The Axial Fan dialog box displays.

In this dialog box, specify the settings for the fan’s construction and cooling.

2. In the Construction area, enter fan parameters in the following fields:
   • Name: Name of the fan
   • Overall Size: Overall size of the fan
   • Fan Diameter: Diameter of the fan
   • Hub Diameter: Hub diameter of the fan
   • Thickness: Thickness of the fan

3. In the Cooling area:

• Select an appropriate flow rate option from the Flow Rate Option dropdown list box. The available options are Fixed or Curve.

 Fan curve determines the relationship between the fan flow rate and the staticpressure. As the fan flow rate increases, the pressure decreases.

 a. If you select a Fixed flow rate, you must specify Fan Flow Rate in the corresponding field. Fan flow rate is a function of the rotating speed calculated using m^3/s. The default value is 0.0094.

 b. If you select the Curve flow rate option, you need to select Fan Curve from the corresponding dropdown list box.

• In the Heat Dissipated field, specify the amount of heat dissipated by the The default is 0.

4. Click OK.

After the fan is successfully added, it appears under the Parts node as shown below:
