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...

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...

How to reduction the noise of fan in design?
Nov 17 , 2021
The specific noise reduction methods of the fan are as follows: (1) Enhance the aerodynamic load of the cascade and reduce the circumferential speed For the axial cooling fan, strong forward blades are used, and the multi blade impeller is beneficial to increase the aerodynamic load of the cascade. Under the same air volume and pressure, the circumferential speed on the outer circle of the impelle...

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 ...
