In Need of Cooling Fans? Here’s How to Get One

Choosing the right cooling fans is a difficult task. The users have to juggle between so many factors only to end up purchasing a wrong equipment. It is a daunting as some people end up considering factors, which do not determine the performance of the fan.

These simple steps will guide you on how to evaluate this equipment:

Conduct thermal analysis; since you want to install cooling fans, it is important to establish the amount of heat generated by the components within that particular environment. What is the approximate cubic feet per minute of the surrounding air that should be moved during the cooling process?

This may involve a critical analysis of various components within the unit. This may include the surface, fluids, etc. During the thermal analysis, it is important to put more emphasis on the worst-case scenarios.

Determine the overall system impedance; this refers to the total pressure drop in system.  As the air goes in and out of the system, it will tend to lose some pressure. Controlling the impedance of the system is a crucial factor and it can be determined by the number of intake and exhaust valves, length of the systems and its complexity.

Evaluate the performance curve; all characteristics of the cooling curves is represented graphically forming the performance curve. Normally, the manufacturer develops these curves for different conditions such as fans speed, volume or system static pressure.

At some point within the curves, there’s the intersection point. This is the operating point of the fan. To ensure that the fan meets the performance requirements, it is important that the proposed operating point meets the fan’s performance curve.

The design of the fan; broadly, there are the axially and centrifugally oriented cooling fans. The axial fans create aerodynamic lift. They are small, light and cheap however; the fans produce a lot of noise and noise vibrations.

On the other hand, the centrifugal cooling fans produce high air pressure and they can be used in very hostile operating conditions.

Having said all these, considering the right design, size and weight are also an important factors to consider. It should be one, which can be integrated in the existing system easily. It can be a challenging process at first. Thus, you can always request for assistance just to be sure that you have the right equipment.
