DC Fans: 8414N/2H Application Field and Working Principle

DC fans are a type of electronically commutated motor that utilizes solid-state circuitry to generate an alternating current from direct current. The 8414N/2H is a particularly special type of DC fan, which is designed to process airflow at a high static pressure and provide power savings in comparison to traditional AC fans. This fan is mostly used in applications where confined spaces limit the area available for air intake and where a higher static pressure is needed for efficient cooling. In this article, we will discuss the application field and working principle of 8414N/2H DC fans.

Application Field

The 8414N/2H DC fans are designed to operate in tight spaces, such as those found in small form factor PC cases or other tight spaces where air intake must be generated at a high static pressure. These fans can be used in situations where there is limited space, and in places where restricted airflow is necessary. Since they are relatively small, these fans can also be used to cool powerful CPUs that generate a lot of heat. The 8414N/2H DC fans can also be used in industrial applications, such as cooling electronic components in enclosed control boxes and cable trays, as well as cooling devices such as motor drives and switchgear. Furthermore, these fans are also suitable for use in medical device applications, including cooling x-ray machines, MRI systems, and other medical equipment.

Working Principle

When discussing the working principle of the 8414N/2H DC fans, it is important to first understand what a DC fan is. As mentioned, DC fans are a type of electronically commutated motor that uses solid state circuitry to generate an alternating current from direct current. The advantage of this type of motor over traditional AC motors is that they are more efficient and require less electricity to operate.The 8414N/2H DC fan utilizes a Brushless DC (BLDC) motor in order to generate its airflow. BLDC motors are inherently more efficient than traditional AC motors, as they use less electricity and generate less heat. The 8414N/2H fan also uses a permanent magnet rotor which eliminates the need for brushes and helps reduce power loss. The motor operates by passing a series of magnetic currents through the stator windings, which produce an alternating current in the rotor windings. The alternating current creates a rotating magnetic field, which in turn causes the rotor to turn, generating airflow. In order for the 8414N/2H DC fan to operate efficiently, it uses a unique airflow direction – exhaust airflow is generated from the sides of the fan, rather than from the top or bottom, as is the case with most other fans. This unique airflow direction helps maximize the static pressure generated by the fan and ensures that air is pushed directly onto heated components, allowing for efficient heat transfer.

Conclusion

The 8414N/2H DC fan is a special type of fan designed to generate high pressure airflow in tight spaces. This fan is predominantly used in PC cases, industrial applications, and medical device applications. The fan is powered by a Brushless DC motor which operates by passing alternating currents through the stator and rotor windings and producing a rotating magnetic field. The airflow generated by the fan is unique, as it is generated from the sides instead of from the top or bottom. This helps to maximize the static pressure generated by the fan and ensures that the heated components are effectively cooled.
