With the continuous development and application of science and technology, more and more electronic devices are applied to medical devices. This also makes these electronic devices more diverse and strict in their environmental requirements. Temperature is one of the most important factors. Temperature has a great impact on any electronic equipment.At high temperatures, almost all parts of the equipment are affected. Therefore, a good cooling fan for medical equipment is extremely important for ventilation and cooling of medical equipment and ensuring the service life of the equipment.

        During our normal use of medical equipment at ordinary times, due to the action of electric current, the interior of medical equipment will heat up to different degrees. If the temperature is beyond the safe range under normal circumstances, install a cooling fan or 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 safety of the equipment. We can often see in movies that when the electronic equipment is used beyond the load, it will burn or even explode, so there is no doubt about the role of the cooling fan on the electronic equipment. Therefore, during the maintenance and repair of medical equipment, the condition of the heat dissipation equipment should also be checked, so as to prevent the circuit components from overheating due to abnormal operation of the heat dissipation equipment.

        With the continuous development of electronic assembly technology, the volume of electronic equipment is becoming smaller and smaller, the system is becoming more and more complicated, and the high heat density has become an irresistible development trend. In order to adapt to the development trend of the times, the cooling fans are also constantly innovating, and new cooling methods are emerging one after another in line with the pace of the times.

        From imaging equipment to surgical instruments, powerful medical equipment in the 21st century is impressive, which is also largely due to the improvement of microprocessor computing power. However, for thermal engineers, these improvements have also paid a corresponding price. The power of the equipment is getting larger and smaller, and the appearance of the equipment is getting smaller and smaller, which also makes our cooling fan work in smaller and smaller space with more and more power, which is also a difficult problem we will face.
