DC fans are commonly used in applications that require cooling, such as computers and other types of electronic equipment. They are also used for air circulation in HVAC systems and for ventilation in industrial settings. The F412R-05LB is a type of DC fan that is popular in many applications. In this article, we will discuss the application field and working principle of the F412R-05LB.

Applications

The F412R-05LB is suitable for applications in which a small form factor is desirable, such as in mobile or embedded applications. It can also be used for cooling electronic components, such as CPUs, GPUs, and memory modules. This fan can also be used in heating, ventilation, and air conditioning (HVAC) systems, where air circulation is required for temperature control. In industrial settings, it can be used for ventilation and for cooling of high-power equipment.

Design

The F412R-05LB has a low-profile design, with a 40mm x 40mm x 10mm frame. It has an impeller with seven blades made of PBT-GF plastic and has an operating temperature range of -10°C to 70°C. The fan has a speed of 5000 rpm and an airflow of 6.84 CFM. The fan needs a 5V DC voltage to operate and can draw up to 0.2A when operating at full speed. The fan does not have a protection system, so it must be used in an environment where it can be monitored.

Working Principle

The F412R-05LB is a type of DC centrifugal fan, which is driven by an electric motor. When the fan is powered, the motor spins the impeller which creates a pressure differential between the inlet and outlet of the fan. This pressure differential causes air to be drawn into the fan and expelled out of the fan. The fan blades are designed to optimize the airflow, and the speed of the fan can be controlled by adjusting the voltage. By increasing the voltage, the fan can be made to spin faster, thus increasing the airflow.

Conclusion

In conclusion, the F412R-05LB is a popular type of DC fan that is suitable for cooling, ventilation, and air circulation in a range of applications. Its small form factor makes it a good choice for mobile or embedded applications, and its speed can be adjusted using voltage control. This fan does not have a protection system, so it needs to be used in an environment where it can be monitored.
