The production of industrial equipment is inseparable from the accessories industrial cooling fan. The main function of the fan is to dissipate heat, cool and remove dust for various sizes of equipment. The general production environment of industrial equipment is relatively harsh. In order not to shorten the service life of the industrial cooling fan, some treatment will be done for the fan. The following are some of the more common anti-corrosion measures for industrial cooling fans.

Appearance treatment of industrial cooling fans: The surface protection treatment of cooling fans usually adopts galvanizing, chrome plating, chemical plating and other methods. These methods are valid in many environments, but for rotating parts, you must choose carefully. Because the substrate and the coating are two kinds of materials, their linear expansion coefficients are different, which will produce different deformations in the elastic deformation of the rotating parts, which will produce a large number of micro-cracks and accelerate the formation of corrosion. Therefore, the appropriate process must be selected according to the actual use environment.

Design of industrial cooling fan: The design of cooling fan is the performance of its core technology, and also affects the service life of cooling fan. In the structural design of cooling fans, the design defects most prone to accelerated corrosion are stress concentration tendencies and interstitial environments. Sometimes the corrosion rate in the metal immersion solution is small, but the formation of gaps can cause severe crevice corrosion due to changes in the chemical and electrochemical states of the internal solution, which requires careful design.

Materials of industrial cooling fans: Different cooling fans use different materials and have different anti-corrosion effects. After selecting the cooling fan model, the strength of the parts is determined from the base surface according to the corrosion resistance of different materials in different environments, the main application environment, working strength and other factors.

Air volume refers to the total volume of air discharged or incorporated by the cooling fan per minute. If it is calculated in cubic feet, the unit of air volume is CFM. In cubic meters, that's CMM. The air volume unit often used by cooling fans is CFM.

Air volume is the most important indicator to measure the heat dissipation capability of heat dissipation fans. Obviously, the greater the air volume, the higher the heat dissipation capacity of the cooling fan. This is because air has a certain heat capacity ratio, and a larger volume of air, which means more air per unit time, carries more heat. So what factors will affect the air volume of the cooling fan?

1. Fan speed. The fan speed refers to the number of rotation times of the fan blades per minute. The unit is rpm. The fan speed is determined by the number of turns of the coil in the motor, the working voltage, the number of fan blades, the inclination Angle, the height, the diameter and the bearing system. Fast speed, that is, the fan out of the air volume is larger, in the case of not considering other factors, fast fan can better heat dissipation, but its disadvantage is also obvious, that is, will shorten the service life. Of course, it is also related to fan bearings. If it is an oil-bearing, too high speed is not necessarily a good thing, and ball bearings can achieve a higher speed.

2. Fan size. In fact, the wind speed and pressure of the same size fan are inversely proportional. The faster the wind speed, the greater the amount of wind, the smaller the wind pressure accordingly, so that the wind can not completely blow to the bottom of the radiator, so that the heat will accumulate at the bottom, so that the cooling effect is weakened. Therefore, if you need to increase the air volume and pressure of the fan at the same time, the only way is to increase the size of the fan. However, increasing the size of the fan brings with it a series of problems, such as being overweight. Therefore, we should not blindly pursue high speed, we should choose the most suitable cooling fan for their products according to the specific requirements of customers.

Cooling fans, as the name suggests, are used for ventilation and heat dissipation. It is widely used in various industries and fields, because in many electronic equipment and machinery, if there is no cooling device installed in the equipment, the working temperature may be too high, which may cause the performance of the equipment to decline, or even be damaged. For normal and efficient operation, a ventilation cooling fan is required. So where are the cooling fans commonly used in our lives?

In the field of home appliances, refrigerators, washing machines, smart toilets, air purifiers, humidifiers, dehumidifiers, etc. all need to be applied to cooling fans. These household appliances are often used, and through It is easy to generate heat when running on electric power, so it is necessary to use a cooling fan to help dissipate heat to prolong its service life.

In the field of medical treatment, during the normal use of medical equipment, under the action of current, the interior of the medical equipment will heat up to varying degrees. If the temperature exceeds the safe range under normal circumstances, install a cooling fan to ensure the normal operation of the equipment during use, which not only protects the service life of the equipment itself, but also improves the safety of the equipment.

In the field of vehicle system, automotive cooling fans are also installed on various parts of the car, and the phenomenon of converting mechanical energy into thermal energy also occurs during the driving process of the car. Therefore, the parts in the car also need to continue to be cooled, such as car seat cushions, LED headlights, etc. If there is no cooling tool, the parts of the car will naturally fail, causing the car to be sent to the maintenance department.

In addition, in addition to the above-mentioned household appliances, medical equipment and automobile fields, cooling fans are also widely used in many places, such as: office equipment (projectors, printers), power communication equipment (frequency converters, inverters, cabinets) and industrial equipment, etc.
