[Do you know about heat dissipation] The role of blades for DC fans

The DC fan converts electrical energy into machinery through DC voltage and electromagnetic induction to drive the rotation of the fan blades. Therefore, the fan housing and blades are an essential whole. Most people know that these two parts are very important, so they What kind of role does it play? First, blade curvature: within a certain range, the greater the blade curvature, the greater the gas kinetic energy at the same speed, that is, the greater the air volume and wind pressure; at the same time, the greater the resistance of the blade, the greater the torque of the motor. Big. Second, the motor diameter: due to the existence of the motor and bearings, DC fan spindle in the central part of the inevitable no air flow

[Do you know about heat dissipation] How to judge the speed value of the heat dissipation fan?

Cooling fans are usually divided into the following three categories: 1 Axial flow: the direction of the airflow outlet is the same as the axis direction. 2 centrifugal: the use of centrifugal force will flow out along the blade. 3 mixed flow type: has the above two air flow modes.

[know no] how to choose dc cooling fan?

When you choose a DC fan, have you encountered any situation that you don't know how to choose? Today, I will teach you how to choose a beautiful and applicable DC fan. In fact, there are six principles for selecting DC fans: First, select the target that can achieve the smallest size. Choose the smallest size cooling fan according to the environmental requirements of our site. Second, select the goal that can achieve the least power consumption. Energy saving is a big goal for us to choose cooling fans. Third, choose the goal that can achieve the least noise. The height of the noise is always a standard for the quality of a fan. So this aspect should be carefully chosen. Fourth, the choice

[Do you know about heat dissipation] The service life factor of DC brushless fan

Generally, the working life of DC brushless fans is affected by the operating environment? working pressure. If the cooling fan works in a high-temperature working environment, it will accelerate the volatilization of the smooth liquid in the oil-immersed bearing, shrink the device, increase the friction force, increase the coil resistance, and increase the heat generation.

[Do you know about heat dissipation] How to deal with DC fan failure?

DC fans are already very common in our daily lives, such as laptops and computer hosts, which all require cooling fans, but when we use DC cooling fans, there will definitely be some failures, so when DC cooling fans have problems When, how should we solve it? 1, the use of DC fan suddenly appear noise is particularly large, sometimes even louder than the sound of the chassis power supply. Solution: This situation is often the fan lubricating oil is dry, or the fan is too dusty. We only need to separate the radiator from the fan, clean the fan, dry it, and add a little lubricating oil.

[know no] what is dc cooling fan cooling?

An important heat dissipation device of modern industrial machinery is called a DC heat dissipation fan. It has many characteristics such as good heat dissipation effect, long service life, simple structure, and convenient installation, and is widely used in mechanical heat dissipation. DC cooling fan is mainly composed of rotor, stator, fan blades and other auxiliary components, the control circuit should have many semiconductor components, now has been stored in one or more IC inside, there are many manufacturers specially designed and manufactured many models of control motor IC supply fan circuit design and use. Different models of IC control circuit is not the same, but the main purpose is

[Know about Heat Dissipation] How to Install DC Fan Accurately

Many people do not know how to install the DC fan after purchasing it. Jiangshan to Electronics will introduce how to install the DC fan. First of all, we must carefully read the operating instructions and product samples of the DC fan, and be familiar with the specifications, forms, rotation direction of the impeller and airflow in and out directions of the fan. Check again whether the parts of the fan are installed properly. Secondly, it is the protection measures before installation. When installing the fan, there must be safety devices to prevent accidents, and the wiring shall be installed by professionals. Things to pay attention to during installation: First, the air duct at the inlet and outlet of the DC fan is separately supported, and the duct is not allowed to overlap
