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...

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...

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...

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...

Is the service life of the DC fan affected by the environment?
Nov 09 , 2021
In daily life, in order to extend the service life of DC fans and reduce the cost of equipment loss, we will regularly inspect and maintain the DC fans in mechanical equipment. However, as the seasons change, the surrounding ambient temperature will change accordingly. In spring and autumn, the temperature is suitable, the winter is bitterly cold, and the summer is scorching, so is the service lif...
