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...

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...

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 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...

What are the causes of fan noise?
Nov 17 , 2021
The following analysis of the causes of fan noise: Fan discrete noise (rotating noise): It is related to the rotation of the impeller. In particular, the noise of high flow exhaust fan is particularly prominent under the condition of high speed and low load. Discrete noise is caused by the interaction between the asymmetric structure around the blade and the circumferential uneven flow field forme...

What is the EC fan?
Nov 29 , 2021
The voltage used in electronic products is divided into direct current (DC) and alternating current (AC).Our usual household appliances, such as electric lights, air conditioners, refrigerators, etc., are AC power supply, while we use DC power supply with batteries (such as mobile phones, flashlights, clocks, etc.).In principle, the efficiency of DC cooling fan is higher than that of AC cooling f...
