[Do you know about heat dissipation] How to judge whether the heat dissipation fan is refurbished

The working principle of the cooling fan is realized according to energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Its circuit principle is generally divided into various forms, the use of different circuits, the performance of the fan will be different. The cooling fan has the characteristics of fast speed, large air volume, good heat dissipation effect, and convenient use. It can be used in different industries. The market size is large and there are many types. When some users buy cooling fans, they may ask whether the seller is a manufacturer. Yes, because there will be refurbished cooling fans on the market, and what manufacturers sell will not be refurbished. The performance of the refurbished cooling fan is not better than the new fan, then

[Do you know about heat dissipation] What are the technical specifications of DC fans

1. Fan test method: 1.1 current: current is measured after continuous rotation for 3 minutes. 1.2 speed is measured after continuous rotation for 3 minutes. 1.3 starting voltage is measured after continuous rotation for 3 minutes. voltage that can start fan operation 1.4 input power is measured after continuous rotation for 3 minutes. 1.5 locking current is measured after continuous rotation for 3 minutes. fan that can lock the machine, lock current Lock the machine in fresh air for 3 minutes 1.6 Air flow data and pressure data are measured according to "AMCA standard" or DIN24163 rules, the data are measured in double pressure chamber, and the pressure number on each side of the pressure chamber needs to be measured.

[Know about Heat Dissipation] Introduction of DC Brushless Heat Dissipation Fan

The structure of the DC brushless cooling fan: it can be divided into four main parts: rotor, stator, outer frame, motor (motor) and some other fragmentary parts. First, the fan rotor part: including fan blades, which are the core of generating air flow and the axis of the cooling fan. It is used to support the rolling of the balanced fan blades, the rotor magnetic ring, the permanent magnet, the key to switch the speed of the propulsion magnetic stage, the outer frame, and the fixed magnetic ring, fan stator part: including supporting springs, separating bearings to balance axes and bearings, providing high speed, low friction, long-life rotation, retaining rings, fixing nodules to rotate the entire component, motor part, production rotation direction, energy

[Do you know about heat dissipation] Improve the quality of the cooling fan from the root

All kinds of equipment will be used in industrial production. These equipment will heat up and burn under long-term working conditions. At this time, it is necessary to use cooling fans to cool down and keep the equipment in good working condition. If it cannot cool down in time, it may cause damage to internal parts and affect production work. It shows the importance of cooling fans in industrial production. So a high performance, good quality cooling fan is the pursuit of each enterprise. Then how can we improve the quality of the cooling fan from the root? 1. Equipment parts Generally, the cooling fan is mainly composed of four parts: rotor, stator, outer frame, motor (motor) and other small parts.

Our company to participate in the Chinese manufacturing network foreign trade training learning

On July 11, colleagues from the foreign trade department of our company participated in the foreign trade training exchange and study meeting held by Made in China in Longhua. At the meeting, the lecturers shared practical experience in overseas customer development. The meeting hall was full of small and medium-sized manufacturing enterprises in Shenzhen, which are committed to developing foreign trade markets. In the global environment of rising international trade protectionism, they made suggestions for Shenzhen enterprises to open up overseas markets and guided the direction of Yang Fan.

[Do you know how to correctly select a DC fan for heat dissipation?

Many people are looking for a few manufacturers when choosing DC cooling fans, and then compare the price to decide, but when choosing DC fans, you can't just look at the price. Here we will teach you how to correctly select the DC fan. 1. Listen to the noise: the same speed, the same voltage, the smaller the noise of the DC cooling fan is better, because the low noise is mainly related to the fan blades, bearings, oil products, assembly structure, etc. The better the shape design of the fan blade, the greater the air volume and the lower the noise; the higher the bearing accuracy, the smaller the friction between it and the shaft core, the more accurate the size matching, and the lower the noise of course; Noise is low, it means friction

[know no] install cooling fan cooling problems should pay attention.

There may be many people who do not know what to pay attention to when installing the cooling fan. We must be careful not to appear in the following ways, otherwise it will shorten the service life of the cooling fan. 1. Dress upside down with the fan blades facing down. If the fan blades are hung for a long time and the rotor magnetism becomes weak, the distance between the fan blades and the motor stator will become empty. The cooling fan may not rotate due to poor induction. Oil-containing fans are most prone to such problems and need some treatment from the structural design. 2. Stuck both sides of the cooling fan, or plug a screw diagonally into the screw hole of the cooling fan. These two heat dissipation methods are easy to cause the cooling fan to follow

[Do you know about heat dissipation] What should be paid attention to when using a cooling fan?

After long-term use, the cooling fan will generally have dust or impurities accumulated. Cleaning and maintenance work can prolong the service life of the fan. The following is an introduction to the matters that should be paid attention to when using the cooling fan: 1. When the fan During operation, do not lock the fan for a particularly long time. The fan will continue to stop and not rotate, resulting in high heat and burning the fan. 2. Do not leave the cooling fan vacant for more than half a year, because if it is not used for a long time, the storage environment will affect the performance of the fan. 3. Please note that the fan will hurt your fingers when running at high speed. When the cooling fan is operating at high speed, be careful not to touch the fan blades to avoid being
