Overview

A DC fan is an electronically commutated cooling device designed to help with air circulation. Among the numerous variants, the OD5020-12HHSS is an offering from the Propeller range and forms a great package for multiple applications. This article focuses on the application field and working principle of the fan.

Application Field

The OD5020-12HHSS is a great fit for high-end servers, IoT devices, and low-profile telecom systems. As a result, it has become an industry standard among electronic cooling solutions. Its slim dimensions and half-length design allow it to fit on systems where limited space is available. Furthermore, its superior air flow of up to 240L/min makes it suitable for high-airflow operation.Other application areas include electric motors, fans, lighting systems, radio frequency antenna, switches, and other electronic components. These components require highly efficient air flow to operate properly and, hence, the OD5020-12HHSS is the perfect choice for them.

Working Principle

The OD5020-12HHSS makes use of a trapezoidal motor, which helps to achieve high air flow even in limited space. It is driven by brushless DC (BLDC) technology. An external driver is used to control the speed of the motor.The trapezoidal motor consists of two moving parts, namely the drive and the stator. As the drive rotates, it induces an electromotive force in the stator, which causes it to rotate in the opposite direction. This motion creates a centrifugal force, which pushes air through the fan blades of the OD5020-12HHSS.The air flow is further enhanced by the incorporation of a double-blade design. The two blades are arranged in opposite directions, which helps to drive air in an efficient manner. Moreover, the blades are designed in a way that they can achieve higher air pressure and flow rate than conventional fans.The advanced BLDC technology further helps to achieve superior air pressure and flow efficiency. The fan motor is powered by an external driver, which is operated using a PWM signal. This signal is used to control the speed of the motor and, thereby, adjust the airflow.

Conclusion

The OD5020-12HHSS is one of the most efficient cooling solutions in the Propeller range. It is an ideal choice for high-end servers, IoT devices, and low-profile telecom systems, among other applications. The advanced trapezoidal motor and BLDC technology allow it to achieve superior air flow, air pressure, and efficiency levels.
