What is the difference between a cooling fan and a silent fan

Fans are very common in our lives. There are many types of fans on the market. Different types of fans have different effects. Cooling fan and ordinary radial fan. Both fans have their own advantages, but many people do not understand. Next, Ruiapple will give you some information about the difference between a cooling fan and a silent fan.

The difference between cooling fan and silent fan

1) Axial fans, axial fans, refer to the airflow in the same direction as the axis of the fan blades (that is, the wind direction is parallel to the axis), such as electric fans, and the fans of external air conditioners are of axial flow type.

2) The cooling fan is also called a local fan, which is a kind of fan commonly used in industrial and mining enterprises. It is different from ordinary fans. Its motor and fan blades are in a cylinder, the shape is a cylinder. Used for local ventilation. Easy installation, obvious ventilation effect, safe and reliable. Air ducts can be connected to send air to designated areas.

The main differences between centrifugal fans and axial fans are:

1. The centrifugal fan changes the flow direction of the medium in the air duct, and the axial flow fan does not change the flow direction of the medium in the air duct. The installation of the former is more complicated. The former motor and the fan are generally connected by shaft, and the latter motor is generally in the fan. The former is often installed at the inlet and outlet of air conditioning units, boiler drums, induced draft fans, etc., while the latter is often installed in the middle of the duct or at the front of the duct outlet.

2. In addition, there are diagonal flow (mixed flow) fans. The wind pressure coefficient of cross flow fans is higher than that of axial flow fans, and the flow coefficient is greater than that of centrifugal fans. Increase the gap between the axial fan and the centrifugal fan. At the same time, it has the characteristics of simple and convenient installation.

There are two types of fans: axial flow and radial flow. They are named according to the airflow direction when the fan is working. When an axial fan works, the blades push air to flow along the axis, which is called a cross-flow fan; when a radial fan works, the blades push air to flow in a direction perpendicular to the axis (ie radial), so it is called a radial fan.

I believe that after the above introduction, everyone has an understanding of the difference between a cooling fan and a silent fan. If you have any questions, please go to Ruiapple for consultation.
