1. First of all, we need to remove the cooling fan. We can fix the small cooling fan with one hand, and the larger cooling fan can be fixed with both hands. However, this operation is very dangerous. If you are not a professional, you should not test it like this. After disassembly, the vibration of the fan has been significantly improved. It can be considered whether the installation angle and installation method of the cooling fan are correct.

2. Remove the cooling fan, and carefully check whether the rack and fan blades vibrate. If there is vibration, it may be the cause of bearing damage. In this case the fan is no longer usable and needs to be replaced. Here we recommend double ball bearing exhaust fans for longer life and greater durability.

3. If the above two situations are not true, we can clean the dust and impurities of the fan and air duct. In addition, you can also consider whether there is a quality problem with the cooling fan.

When the cabinet is running, it will generate a lot of heat. If it is not dissipated in time, it will cause the equipment to overheat and burn down or cause some wires to short-circuit. So when we install the cabinet, we usually install one or more cooling fans on the cabinet. Especially for cabinets with high efficiency and long service life, this can improve the cooling capacity of the cabinet. So how to install and choose the cabinet cooling fan? Please read on.

一、Fan installation

1. First of all, we need to determine the installation direction of the fan. The direction of the fan installation depends on whether your cabinet needs to take in the air or discharge the hot air in the cabinet to the outside. Generally speaking, the positive pressure in the cabinet should be maintained, so the air should be introduced into the cabinet. Because if the fan exhausts air outside the cabinet, it will cause negative pressure inside the cabinet, and the outside air will directly enter through the gaps in the cabinet door. This unfiltered air enters the cabinet directly, causing dust to build up inside the cabinet over time. However, the air entering the cabinet needs to be filtered by filter cotton, which can filter out the dust in the air, so as to avoid the failure caused by dust accumulation in the cabinet. Therefore, when installing the cooling fan of the cabinet, the positive pressure is better than the negative pressure, that is, the air intake into the cabinet is better.

2. We also need to clarify the opening position of the fan. When installing the fan, the positions of its air inlet and outlet also need to be carefully considered. Because hot air is less dense than cold air, the air flow in the cabinet will be from bottom to top. Therefore, under normal circumstances, the lower part of the front door or the side panel of the cabinet is used as the air inlet, and the upper part is used as the exhaust port. However, when the hotspots of some devices are on the top or side or the front door, the cabinet cannot open holes for fans. At this time, it is necessary to open a hole on the top, and the installation direction of the fan is to exhaust the air outside the cabinet, not to enter the cabinet.

二、Fan selection

1. Air volume. If the space in the cabinet is relatively large, we'd better choose a cooling fan with a larger air volume. Because the higher the speed, the greater the air volume of the fan, so we can choose a high rpm exhaust fan.

2. Power consumption. The greater the power consumption, the shorter the fan bearing life, so if the fan has met the customer's requirements in other aspects, try to choose a cooling fan with low power consumption.

3. Noise. The cooling fan tends to generate a lot of noise when it rotates at high speed. Therefore, you need to pay attention to the performance of the cooling fan when choosing to avoid excess performance and reduce unnecessary noise.

As cars become more and more common in life, cooling fans are also widely used in different cars. These automotive cooling fans need to be maintained after a period of time, which is conducive to long-term use and prolong the service life of the fans. The next content is to introduce some car cooling fan maintenance methods.

1. First of all, open the cooling fan shell, then open the cooling fan, and then turn off the power supply. Blow with an air gun at 3 cm away from the cooling fan. After blowing the dust off the surface, wipe the remaining dirt above the fan blades with industrial alcohol. From the front of the device to the back, it needs to be cleaned and then rotated repeatedly until it is clean.

2. There are many factors affecting the wind speed of the automobile cooling fan, among which the most important factor is the bearing of the cooling fan.

Ball bearings: Long-term oxidation and accumulation of dirt and dust of the bearings of ball bearing exhaust fans will increase the friction resistance of the bearings and gradually reduce the fan speed.

Oil-bearing: With the longer the use time of the cooling fan of oil-bearing, the oil in the bearing gradually decreases, resulting in the speed of the cooling fan becoming slower.

The bearings of the cooling fans rotate repeatedly when they are used, which will shorten the life of the fans as well as produce wear. So we need to maintain the bearings of the automobile cooling fan in different ways according to the characteristics of different bearings.

3. The intake network port of the automobile cooling fan should be kept clean to prevent airflow obstruction. The intake network port can be cleaned with a soft brush or compressed air.

In recent years, LED lighting has become an increasingly popular choice in residential and commercial lighting applications. However, like any technology, it is important to address potential issues such as overheating. This is the function of the cooling fan.

In today's world, the importance of proper heat dissipation cannot be overemphasized. This is especially true for electronic devices, as they generate a large amount of heat during operation. To address this issue, cooling fans have become an indispensable part of many electronic devices, including LED lighting. A type of heat dissipation fan commonly used for this purpose is an axial flow fan.

The axial cooling fan is designed to move air in a specific direction, parallel to the fan shaft. This makes them very suitable for cooling electronic devices that generate heat in specific areas. By guiding the air towards the heat source, these fans can effectively dissipate heat and maintain the safe operating temperature of the equipment.

When considering purchasing axial fans, it is important to consider the axial flow fan wholesale price. It is also important to consider the specific requirements of the application, such as the voltage required for fan operation, axial cooling fan 5v, axial cooling fan 24v, axial cooling fan 110v, axial cooling fan 220v, etc.

Cooling fans are used in many places in life and are indispensable auxiliary equipment. It is widely used in traditional or modern equipment such as consumer electronics, automotive electronics, medical equipment, heaters, air conditioners, car freezers, environmental protection equipment, and refrigeration equipment. The cooling fan has a service life. If it is used improperly, cooling fan life will naturally be shortened. To avoid shortening its service life, the following are the matters needing attention when using cooling fans.

1. It is forbidden to touch the fan blades and power cord of the cooling fan at will, otherwise the shaft and power cord will be easily damaged.

2. Avoid dust, water droplets and insects from entering, which will affect the service life of the product.

3. Do not use the fan in flammable gas or any harmful environment, which can reduce damage.

4. Do not leave the cooling fan idle for too long after purchase, as it may affect the normal use of the fan.

5. When the fan is in use, do not use external force to stop the fan. If it is stopped for a long time by external force, it is easy to cause the fan to overheat or burn directly.

6. When the fan is accidentally dropped from a certain height during operation, it will have a certain impact on the balance of the cooling fan blades. If there is a problem, replace the cooling fan in time.

In general, the higher the fan speed, the greater the air volume. The cooling fan generates airflow by rotating the blades, and an increase in speed causes the blades to push more air per minute, and when more air can be pushed, the volume of air will also increase. So when customers pursue high air volume, they often choose high rpm exhaust fans.

(12038 DC fan is used as an example.)

It should be noted that although there is a positive correlation between speed and air volume, the relationship is not linear. In some cases, as the rotational speed increases, the increase in air volume may slow down. This is due to the influence of the fan's design and performance characteristics as well as hydrodynamic effects.

Hydrodynamic effects are physical phenomena and behaviors that occur when involving the movement of fluids, such as air. First of all, when the fan rotates, there will be resistance between the blade and the air, and the larger resistance will reduce the air volume, while the smaller resistance will increase the air volume. In addition, the shape and Angle of the fan blades also affect the pressure difference of the air, which in turn affects the size of the air volume.

Secondly, during the operation of the fan, the turbulence generated by the rotating blade will lead to the instability of the air flow, thus reducing the air volume. The shear layer will form higher and lower velocity airflow regions, which will also affect the distribution and size of the air volume.

In addition, the design of the import and export area, boundary layer effect and fan rotation will have an impact on the fan; And other factors of the cooling fan, such as blade design, blade number, fan diameter and motor power, will also affect the air volume.

With the development of society, our country has also become a big country of machinery and equipment. Because of the heat dissipation requirements of mechanical equipment, cooling fans have also become an indispensable part of equipment production. It is not only used in industrial equipment and electrical equipment, but also in medical equipment. Medical equipment cooling fans are different from cooling fans used in ordinary production and processing industries, and their requirements are more stringent. However, after using the equipment for a long time, it is inevitable that there will be some failures. For example, the cooling fan of medical equipment may trip and fail.

The shutdown caused by the trip of the cooling fan of medical equipment is a forced shutdown, which will not only directly stop the normal operation of the fan, but also cause a series of hazards. The hazards of cooling fan tripping: This will not only cause damage to the cooling fan components of medical equipment, but also directly lead to the scrapping of the cooling fan motor, which will bring huge losses to users. In response to this problem, what needs to be analyzed is the reason for the tripping of the cooling fan of the medical equipment, so as to provide a basis for formulating a solution.

1. The opening of the outlet damper. If the opening of the air valve at the outlet of the cooling fan of the medical equipment is small, the generated air volume cannot be discharged in time. When the wind pressure inside the device reaches a certain level, it will cause a trip. At this time, the air valve can be adjusted appropriately. If it still does not work, it is necessary to consider replacing the fan.

2. Pipeline problems. If the cooling fan of the medical equipment is equipped with a short dust removal pipe and the valve is closed, the cooling fan motor will trip due to insufficient system resistance. But the pipeline can not be set too long, which will also be unfavorable for the work of the cooling fan.

3. Electrical failure. Electrical faults can cause the fan to require too much shaft power, which can overload the motor and cause a trip when the current exceeds the rated value.
