[Heat Dissipation Know No] Noise Parameters of Micro Cooling Fan

As the name implies, the miniature cooling fan is a small and mini cooling fan. It is applied in a small space. With the development of science and technology, the more convenient the equipment we require, the better. Therefore, the application of the miniature cooling fan will become more and more extensive. Today, let's discuss the noise factors of the miniature cooling fan. We all know that the noise of the miniature cooling fan is relatively smaller than that of the large size. So what factors are related?

[know no] micro heat dissipation fan noise causes and solutions?

1. What are the main factors related to noise? The noise of the micro fan is related to friction and air flow. The higher the speed and the greater the air volume, the greater the noise caused, and the vibration of the micro fan itself is also a factor that cannot be ignored. Of course, the high quality micro fan's own vibration will be very small, but the first two are difficult to overcome.

[Do you know about heat dissipation] What you should know about heat dissipation fans

As we all know, there are many industries in the market that use cooling fans, ranging from electronic products to refrigerator cabinets and cooling fans to ensure that the product temperature is controlled within a controllable range and extend the service life of the product. The cooling fan market is large, the competition among the cooling fan manufacturers is fierce, and the functions of the cooling fan models of different manufacturers are also different.

[Know about Heat Dissipation] Talking about DC DC Heat Dissipation Fan

DC DC fan input is DC, the general DC voltage is: 3V, 12V,24V,32V,48V,5V,60V,25.5V,42V,18V,15V. The operation principle is based on Ampere's right-hand rule. When the conductor passes current, a magnetic field will be generated around it. If the conductor is placed in another fixed magnet, suction or repulsion will be generated, causing the object to move. Inside the fan blade of the DC fan, a rubber magnetic strip that has been filled with magnetism before is attached. Around the silicon steel sheet, two sets of coils are wound on the axis part, and a Hall induction component is used as a synchronous detection device to control a set of circuits, which makes the two sets of coils wound on the axis work in turn. The silicon steel sheet produces different magnetic poles, which generate attraction and repulsion with the rubber magnet. When the suction repulsion is greater than the static friction of the fan, the fan blades naturally rotate. Because the Hall induction component provides the synchronization signal, the fan blade can continue to operate. As for its direction of operation, it can be determined according to Flemming's right-hand rule.

[Know about Heat Dissipation] Causes and Treatment Measures of Noise Generated by Cooling Fans

During the use of the cooling fan, there must be sound, but the noise generated by different fans is also different. There are large and small. How are these sounds generated and how to deal with them? 1. Due to the vortex generated by the blade will also produce noise During the operation of the fan, the back of the moving wing will produce eddy currents, which will not only reduce the efficiency of the fan, but also generate noise. During the operation of the fan, the back of the moving wing will produce eddy currents, which will not only reduce the efficiency of the fan, but also generate noise. In order to reduce this phenomenon, the installation angle of the blade should not be too large, and the bending of the fan blade should be smooth, and the sudden change should not be too large.

[Heat dissipation knowledge] Classification of cooling fans and application of their working principles

Consistent wind direction drains to the outside of the chassis. Cooling fan The working principle is realized by energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Classification 1. Axial fan: The blades of the axial fan push the air to flow in the same direction as the shaft. The impeller and propeller of an axial fan are somewhat similar. When it is working, most of the airflow flows parallel to the shaft, in other words, along the axis. 2. Centrifugal fan: When the centrifugal fan works, the blades push the air to flow in a direction perpendicular to the shaft (ie radial). The air intake is along the axis, while the air outlet is perpendicular to the axis.
