The Influence of DCDC conversion module Fan Vortex on Heat Dissipation(1)


AC-DC power module

The influence of power supply heating is important in terms of conversion compliance, circuit board layout and cooling mode. In DCDC conversion module or electronic system, air cooling is usually used as the cooling mode. Therefore, heat sinks and axial fans are widely used.

Because the working principle of the axial flow fan is to drive the blades connected with it to rotate Weifang at the given speed of the motor through the operation of the motor, so as to generate a positive pressure difference between the front and back of the blades, and drive the air around the blades to move along the fixed direction of the motor shaft. Therefore, the axial fan has the characteristics of low head and large flow.

●High quality and reliable. Module power supply generally adopts fully automatic production, and is equipped with high-tech production technology, so the quality is stable and reliable.
Wide range of uses: The modular power supply can be widely used in various fields of social production and life such as aerospace, locomotives and ships, military weapons, power generation and distribution, post and telecommunications, metallurgy and mining, automatic control, household appliances, instrumentation and scientific research experiments. In particular, it plays an irreplaceable and important role in the field of high reliability and high technology.

Usually, when people choose axial fans, they only consider the above characteristics, ignoring a series of effects caused by the rotation of axial fan blades on the forced flow of air. In fact, the fluid passing through the axial fan does not move in the single direction of the motor axis, and there is also a velocity component on the fan blade section perpendicular to the motor axis. Therefore, Baidu Keyword, the fluid driven by the axial flow fan is actually a moving fluid that rotates forward with the motor shaft as the axis.
