DC Fans

DC fans are becoming increasingly popular in many applications as they offer advantages in size, weight and power consumption over traditional double multiple fan systems. DC fans have been found to be most suitable for cooling smaller electronic devices such as mobile phone, notebook computers, and other portable devices. As an alternative to AC or shaded pole motors, DC fans have the advantages of low cost and high efficiency, as well as the ability to be designed smaller.

The OD4020-12HS is a size 40mm x 20mm DC fan which is used in a variety of applications requiring a reliable cooling solution in a confined space. It is provided with a 12V nominal voltage, a 0.291A current, a 3596±10% RPM rotating speed, and an airflow of 8.8M3/hr. It is also designed with a durability to achieve up to 50,000 hours service life. This fan is most suitable for applications with multiple cooling requirements, such as communication and medical equipment, and other small electronics.

The working principle behind the OD4020-12HS is the basic operation of a DC fan: an electric motor moves an impeller that produces airflow. Specifically, electrons from the power source are sent to the fan motor, then the fan motor rotates the impeller within the fan, which then produces an airflow, thereby cooling the system. The speed of the motor affects the airflow, as a faster motor will result in an increased airflow. This fan is also designed with a thermistor to detect changes in temperate, which helps to provide a greater cooling capacity.

Overall, the OD4020-12HS is a size 40mm x 20mm DC fan which is suitable for multiple cooling requirements. Provided with a 0.291A current, 3596±10% RPM rotating speed, and an airflow of 8.8M3/hr, this fan is designed with a durability to achieve up to 50,000 hours service life. The working principle behind this fan is the basic operation of a DC fan involving an electric motor that moves an impeller that produces airflow. This fan is designed with a thermistor to detect changes in temperature and to provide a greater cooling capacity.
