COOLING FAN DECIBEL RATINGS CHART PDF

The air flow resistance becomes the pressure energy that increases the static pressure within the device. This situation is very similar to the role of impedance in the flow of electrical current: when impedance is low, the current flow is large, and when impedance is high, the current flow is low. Capable of generating a large air flow, axial fans are suited for applications requiring ventilation cooling where the entire space inside the equipment must be cooled. Since air flows along the axis of rotation, the structure is kept compact. The propellers (fan blades) located in the circular flow path between the cylindrical hub and casing are used to force-feed air in order to generate air flow in the direction of the axis of rotation. Overheat protection is also discussed through the use of low-speed alarms, stall alarms, and thermal protectors. The following explains the structure of axial fans, centrifugal blowers and cross flow fans, as well as air flow-static pressure characteristics. The features of cooling fans differ according to their air-blowing system. In order to avoid these problems, the appropriate cooling unit for these systems must be selected. Cooling fans and blowers are essential to applications in the presence of heat. Overheated equipment can lead to many problems, including failure, shorter product life, early deterioration of parts, malfunction, and other safety risks.
