When the power supply is working, it will generate heat. When the heat reaches a certain amount, it will affect the normal work. In severe cases, the power supply will be damaged. Therefore, a cooling fan will be used to discharge heat in time to cool down. The power supply exists as the heart of the device, so the cooling fan The requirements are also relatively high, the following will introduce the characteristics of the power supply fan.

Under the current general trend of "energy saving and emission reduction", the development of electric vehicles is unstoppable, and with its continuous development, the demand for charging piles for electric vehicles is also increasing. The charging speed is a very important indicator of the charging pile, and the charging speed can be faster and faster, which is not only a requirement for batteries and cables, but also a very high requirement for the cooling system of the charging pile.

With the development of the times and people's pursuit of quality life, more and more families tend to choose home central air conditioners. In the inherent impression of the public, the double fan has higher cooling efficiency and better cooling and heating effect. Small heat exchange area and low heat exchange efficiency affect the effect of cooling and heating

In the process of using cooling fans in the home appliance industry, the reliability of the fan bearing system software determines the service life, noise and reliability of the heat pipe cooling fans. Generally, the cooling fan bearings in the home appliance industry can be divided into two types: oil-impregnated and ball bearing fans. The price of oil-impregnated fans is lower, but oil-impregnated bearings are drag friction and have a larger surface. In the long-term use process, the lubricating oil is used faster, so the bearing is more likely to be damaged, the noise is large in the middle and later stages, and the cycle is short. The ball bearing is a flip friction, which has the characteristics of high efficiency, low heat generation, small friction coefficient and small damage. Therefore, the service life is generally up to 40,000 hours. With the continuous expansion of heating capacity in the home appliance industry, oil-containing fans have long been unable to consider the cooling requirements of the home appliance industry. Ball fans have gradually become cooling fans in today's home appliance industry.

During the use of medical equipment, due to the action of current, the interior of the medical equipment will be heated to different degrees. Especially the control board, the normal working temperature of medical equipment is constantly rising, and the temperature exceeds the safe range. It is necessary to install a cooling fan or a cooling device 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 The safety and stability of equipment use. We can often see in movies that when the electronic equipment is overloaded, it will burn or even explode, so the role of the cooling fan on the electronic equipment is beyond doubt. Therefore, during the maintenance and repair of medical equipment, the condition of the heat dissipation equipment should also be checked, so as to avoid the failure of the circuit components due to the overheating of the circuit components due to the abnormal operation of the heat dissipation equipment.
