Many home appliances need heat dissipation during use, so cooling fans are usually installed to achieve the purpose of heat dissipation. In the process of using home appliance industry cooling fan, fan bearings play a decisive role in the service life, noise and reliability of cooling fans. According to the fan bearing, it can be divided into oil bearing exhaust fan and ball bearing exhaust fan. The price of oil bearing fans is relatively low, but oil bearings are dragging friction. In long-term use, the lubricating oil is used faster, so the bearings are more likely to be broken, and there will be loud noises in the middle and late stages. The ball bearing belongs to the rolling friction, which has the characteristics of high efficiency, low heat generation, small friction coefficient and small damage. Therefore, the service life is generally longer. With the development of the home appliance industry, oil bearing fans have been unable to meet its heat dissipation requirements, so ball bearing fans have gradually become the mainstream of home appliance industry cooling fan today.

 

During the production and processing of cooling fan bearings, the key stages of quality include the production and manufacture of bearing steel balls, the use of refined oil, cleaning during processing, the application of aerospace-grade stainless steel plates, and high-precision assembly lines. Since the bearing has a great influence on the cooling fan, it is particularly important to control the quality of the bearing.

 

In addition, high-quality bearings and fake and inferior bearings do not look very different in appearance, but their technological content cannot be compared. The significant technical differences in the production process of the two bearings can be reflected through the analysis and comparison of the bearing preload characteristics. Preloading refers to the entire process of fixing the balls into the bearing sleeve, which stipulates that the balls are inseparable from the surface of the bearing sleeve, and there is no play. Whereas in inferior bearing manufacture, the left and right bearing sleeves are directly aligned before preloading. There is no doubt that there will be some deviation between the steel ball specification and the bearing sleeve specification, so after preloading the bracket bearing, there will always be 5-10 gaps between the ball and the bearing sleeve, which greatly increases the degree of embrittlement damage, Reduced bearing life. In the same overall process, when high-quality bearings are produced and manufactured, the relative spacing between the left and right bearing sleeves during preloading is 5 microns, so that the bearing sleeves will firmly lock the balls after being stressed, thereby reducing the clearance to zero. In this way, during the operation of the fan, the balls are not easy to vibrate, thereby minimizing the damage and ensuring the stable and long-term high-speed operation of the cooling fan.

The cooling fan blade is an important part of the cooling fan, which affects the performance and parameters of the cooling fan. These fan blades are usually made of plastic or metal materials, and generally consist of a plurality of fan blades. When the fan is running, the blades create airflow, which helps cool objects. Next, let's take a deeper look at the fan blades of cooling fans from three aspects.

1. The role of fan blades

The role of the cooling fan blade is to help the radiator to send heat to the environment, so that the device can be kept in an appropriate temperature range. The cooling fan consists of a motor and a set of fan blades. When the motor is running, the fan blades will rotate to remove heat from the radiator. This helps protect devices from overheating damage and maintains them in proper working order.

2. The material of the fan blade

Cooling fan blades are usually made of lightweight heat-resistant materials, such as plastic, aluminum alloy cellulose board, etc. These materials conduct heat efficiently and can be rotated at high speeds without damage while in operation. In addition, they have good insulating properties and can prevent electrical short circuits. Fan blades made of plastic are light, wear-resistant, and corrosion-resistant, and are usually used in household appliance cooling fans.

3. Performance of fan blade

The performance of cooling fan blades depends on factors such as the material, size and shape of the blades. Generally speaking, the more complex the shape of the fan blade, the better the heat dissipation performance. In addition, the size of the fan blade will also affect the heat dissipation performance. Generally speaking, the larger the fan blades, the better the cooling effect, but this also means that the fan will be larger, heavier, and will take up more space. Therefore, when selecting a cooling fan, various factors need to be considered in order to select a cooling fan with the most suitable number of blades according to actual needs.

Want to know what makes an air-cooled refrigerator special? Don't worry, today we're going to focus on a component that can't be ignored: the cooling fan. In fact, cooling fans play a crucial role in air-cooled refrigerators, and they have some compelling special designs and features, so let's take a look.

First of all, the location of the cooling fan deserves attention. They are usually located on the back of the refrigerator and are closely connected to the condenser. The choice of this location is not accidental, as it is able to effectively expel the generated heat, ensuring that the inside of the refrigerator maintains the proper temperature. This design improves the cooling effect while avoiding problems caused by overheating.

Secondly, the design and materials used in the cooling fan are also very special. They usually consist of efficient fan blades and a main air lead. Just like Chungfo's design and production of blades capable of low noise output high air volume, these fan blades are specifically designed to produce a strong airflow to provide sufficient cooling effect. The selection of materials takes into account the impact of long-term operation and low temperature environment on the fan, so that it can work in difficult conditions for more than five years without trouble.

Finally, the cooling fan also has intelligent control and adjustable functions. Some modern air coolers are equipped with intelligent control systems that can automatically adjust according to the temperature and load in the refrigerator. This means that the cooling fan can automatically start and stop as needed to work more efficiently. This feature helps to save energy and extend the life of the fan. The PCB board of the cooling fan produced by us is almost assembled by a professional technical team of workers, so when the customer requires the fan to have a self-starting function, TC temperature control function, RD alarm signal and so on, we can meet. And our company has many models of cooling fans are used in the refrigerator, such as D09232 this model of DC fan is the classic model of refrigerator application, most of the well-known refrigerator factories will use.

In general, the cooling fan in the air-cooled refrigerator has many special features. From the selection of their location, to the choice of design and materials, to the application of intelligent control and adjustable functions, these fans make an important contribution to the performance and effectiveness of the refrigerator.

We can provide professional customization of cooling fans according to customer needs. If you have this need, please feel free to contact us.

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.

The importance of air density for cooling fans

The air density is the key factor affecting the cooling performance of the cooling fan. Under different environmental conditions (such as temperature, altitude and climate), the air density will change, which will affect the heat dissipation effect. As a professional cooling fan manufacturer, our products cover 110V AC cooling fan and 220V AC cooling fan. We are both a professional 110 v ac cooling fan factory and a reliable 220 v ac cooling fan factory , committed to providing high-quality cooling solutions in various air density environments.

Influence of air density on cooling effect of cooling fan

High-density air (cold air) environment: In an environment with higher air density, such as a low temperature environment, the air contains more molecules per unit volume, making the air able to carry more heat, so the heat dissipation effect is better.

Low-density air (hot air) environments: At higher temperatures or at high altitudes, the air is less dense, reducing its heat transfer capacity. In this environment, the efficiency of the cooling fan will be reduced, especially for 220V AC cooling fans, and the performance in low-density air is an important design consideration.
