Power Supply
When the power supply works, it will generate heat. When the heat reaches a certain amount, it will affect the normal work. In serious cases, it will damage the power supply, so the cooling fan will be used to discharge the heat in time to cool down.

Popularization of the definition of cooling fan
2022-08-03
Cooling fans, English name: Cooling fans. The technology and performance of cooling fans have fully reached a mature stage, and new technologies are constantly emerging. The size of the fan is from 8mm to 280mm, the voltage is 5V, 12V, 24V, 48V, 110V, 220V, 380V, and the shape is square, round, olive, etc.
The popularization of the definition of DC fan
2022-07-27
Over DC voltage and electromagnetic induction, the electrical energy is converted into machinery to drive the fan blades to rotate, collectively referred to as DC fans. working principle Simply put, depending on the continuous switching of the coil and the IC, the induction magnetic ring drives the fan blade to rotate.

The popularization of the definition of cross-flow fans
2022-06-28
Cross-flow fans are small high-pressure centrifugal fans with forward-facing multi-blade impellers. The gas enters the impeller from one side of the outer edge of the rotor, and then passes through the interior of the impeller and is discharged from the other side, where the gas is subjected to the force of the blades twice in the impeller. Under the conditions of the same performance, it is small in size and low in speed. Compared with other types of low-speed fans, cross-flow fans have higher efficiency. Its axial width can be selected arbitrarily without affecting the flow state of the gas, and the gas still maintains a uniform flow over the entire width of the rotor. Its outlet section is narrow and long, suitable for installation in various flat equipment for cooling or ventilation.
2022-06-28
With the continuous development of the electronic industry, many electronic products are widely used, and the demand is also increasing. The demand for accessories required for electronic products is also increasing, such as DC cooling fans. What are the advantages of DC cooling fans that are worthy of favor and pursuit by businesses? Here, DC cooling fan manufacturers briefly introduce the advantages of DC cooling fans.
Some information about ball fans?
2022-06-28
When we use the ball fan, we must have a lot of basic information that needs to be mastered, such as its characteristics, functions and some matters needing attention in its use, etc. Most people should still not know about these. Let me give you a detailed introduction, I hope it can help you.
