How to Determine the Quality of the Cooling Fan
Aug 11 , 2021
Cooling Fans mainly include axial flow fans and centrifugal fans, and axial fans are divided into DC axial fans and AC axial fans. With the increasing use of cooling fans, more and more fans appear on the market. However, the quality of these fans varies from good to bad. If you want to buy a good fan, you must know how to distinguish the fake and inferior of the fan. So how to judge the fake and ...

What should be considered when choosing a DC fan？
Sep 01 , 2021
As we all know, DC fans are the key cooling equipment for modern industrial machinery. It consists of stator, rotor and commutator. The basic structure is generally composed of a motor, bearings, blades, housing, power plugs and wires. According to different power supply methods, there are two types of motors: DC motors and AC motors. So do you know what to consider when choosing a DC fan? Speed o...

Why the blades of an axial fan are odd and not even？
Sep 08 , 2021
First of all, many people find that the structure of the cooling axial fan blades is composed of odd numbers such as 3, 5, 7, 9 and 11. However, many consumers are not very familiar with it, and are curious, whether this is just a design coincidence or another mystery Where? As we all know, the actual heat dissipation effect of a cooling fan largely depends on the design of the blade pitch and the...

Components of the Cooling Fan
Sep 16 , 2021
Cooling fans have a wide range of applications, and there are many types of relative cooling fans, such as axial cooling fans, centrifugal cooling fans, and cross flow cooling fans. But its composition and structure are similar. For example, an axial fan is mainly composed of four parts: the rotor, the stator, the motor, and the outer frame. 1. Rotor part: The rotor part of the cooling fan is comp...

What is the difference between centrifugal, axial and cross flow fan blades?
Sep 26 , 2021
1. Centrifugal fan Centrifugal blower fan is based on the principle of converting kinetic energy into potential energy, using a high speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from the axial direction, changes to...

Does the DC cooling fan have an impedance protection function?
Oct 19 , 2021
DC cooling fan is an important cooling equipment for modern industrial machinery. Its basic structure is generally composed of motors, bearings, blades, housing (including fixing holes), power plugs and wires. The motor is the core of the DC cooling fan. It is generally composed of a stator and a rotor. The stationary part of the motor is called the stator, and the part that rotates when it is run...
