[Do you know about heat dissipation] Why does the heat dissipation fan fail?

With the needs of machinery and equipment, cooling fans are applied in many fields. Generally, the normal heat removal of the fan can ensure the operation of the machine. Otherwise, various failures will occur, such as the shutdown of machinery and equipment. Therefore, in order to reduce the occurrence of failures, we must understand the cause of the failure and deal with it in time. Then why does the cooling fan fail? First, the cooling fan design reasons: the cooling fan engineer improper design, in the design did not take into account the coordination of parts, poor dynamic characteristics, resulting in vibration or noise when the machine is running. The structure is unreasonable, the use of steel is not appropriate, resulting in stress concentration, the fuselage material is prone to crack

[Do you know about heat dissipation] How to extend the service life of the cooling fan?

As the name suggests, the cooling fan is mainly used for heat dissipation and cooling of various equipment. It is mainly used in industry. The general industrial environment is more complicated, so it is often necessary to do some treatment on the cooling fan to avoid corrosion. This is also to extend The life of the equipment reduces costs. What is the main work? 1, cooling fan surface treatment cooling fan surface protection treatment, usually using galvanized, chrome plating, chemical plating and other methods. These methods are effective in many environments, but for rotating parts, you need to choose carefully, because the base material and coating are two kinds of materials, the coefficient of linear expansion

[Do you know about heat dissipation] What is the difference between DC fan and AC fan

With the increasing market demand for fans, it has also been applied in various occasions and industries. Although DC fans and AC fans can be seen everywhere in life, many people are not very clear about the characteristics of these fans, so the following is a brief introduction to the differences between these fans. First, the power supply is different. DC fans work by direct current, while AC fans run by alternating current. Second, the working principle is different: the principle of the DC fan is to convert electrical energy into mechanical energy through DC voltage and electromagnetic induction to drive the blades to rotate quickly, relying on the coil and IC to continuously switch, and the induction magnetic ring drives the blades

[Do you know about heat dissipation] Whether the environment will affect the service life of DC fans

In daily life, I believe that most people in order to extend the service life of the DC fan to reduce the cost of equipment loss will be on the mechanical equipment in the DC fan to do regular inspection and maintenance, then does anyone know whether the surrounding temperature will affect the fan. Due to the influence of its material and bearing, the DC fan is indeed affected by the environment and working pressure. If the DC fan operates in a high-temperature operating environment, it will accelerate the evaporation of the lubricating liquid in the oily bearing, causing conflicts due to the expansion of the equipment, and the coil resistance It also increases and falls into a vicious circle of heat and heat, which will speed up the electronics

[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.
