How to judge the cooling performance of the cooling fan?
Nov 03 , 2021
Cooling fan can be selected from the main parameters such as bearing, airflow, pressure, size, motor and so on. What are the specific factors that will affect the performance of the cooling fan? How do we judge whether it is a high performance cooling fan? 1. Related to the bearing used by the cooling fan The most commonly used bearings for cooling fans are sleeve bearings and ball bearings. Sleev...

What are the main reasons for the noise sources of fans?
Oct 26 , 2021
Noise is a kind of noise that makes people feel noisy and boring, and its degree sometimes varies with people's mood. But continuous noise will also pollute the surroundings. The causes of noise generated by general cooling fans can be divided as follows: 1. Noise caused by blade rotation When the blade rotates, it will generate friction or impact with the air. High rpm exhaust fan, the faster the...

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...

How to choose a good cooling fan?
Oct 11 , 2021
With the continuous improvement of people's living and economic level in China, DC cooling fans are more and more widely used in our lives, which is also the main reason for many DC cooling fans suppliers. So, among so many suppliers, how do we choose a good cooling fan? 1. Choose from the appearance: From the outer surface, it should be thicker overall, with pure color (especially black), and the...

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...

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...

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...

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...

Cooling Fan - What are the relevant parameters
Aug 25 , 2021
Airflow The airflow of cooling fan refers to the total airflow of air discharged or absorbed by the cooling fan per minute. If calculated in cubic meters, it's the CMM. The airflow unit often used by cooling fans is CFM (about 0.028 m3 / min). Large air volume fan, airflow is the most important index to measure the cooling capacity of cooling fans. Obviously, the larger the airflow, the highe...
