The medical equipment cooling fan has the beneficial effects of being convenient to connect and obvious in cooling effect.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cooling fan for medical equipment. Background technique [0002] China's medical equipment industry has grown from small to large, and has a considerable scale, and has maintained a relatively rapid growth rate. According to the data of the National Bureau of Statistics, by the end of 2014, China's medical equipment industry had reached 420 billion yuan, with an annual growth rate of 15%. , far higher than the annual growth rate of the international medical equipment industry of 7%. In the global market, the proportion of medical equipment and pharmaceutical consumption is about 1:1, and the proportion of medical equipment in developed countries is even higher, while the proportion of medical equipment and pharmaceutical expenses in China is about It is 0.32:1, which is much lower than the international average level. Therefore, there is still a large gap in China's medical e...

[0002] China's medical equipment industry has grown from small to large, and has a considerable scale, and has maintained a rapid growth rate. According to the data of the National Bureau of Statistics, by the end of 2014, China's medical equipment industry reached 420 billion yuan, with an annual growth rate of 15%. , which is much higher than the annual growth rate of the international medical equipment industry of 7%. In the global market, the proportion of medical equipment and pharmaceutical consumption is about 1:1, and the proportion of medical equipment in developed countries is even higher, while the proportion of medical equipment and pharmaceutical expenses in China is about It is 0.32:1, which is much lower than the international average level. Therefore, there is still a large gap in China's medical equipment industry, and there is still a large market space for the medical equipment industry. Since medical equipment is a high-end precision equipment, the internal structure is complex and there are many circuit components. Therefore, higher requirements are put forward for the heat dissipation of medical mechanical equipment. At present, the commonly used cooling fan motors for medical equipment have low cooling efficiency, large fan rotation noise, and vibration problems during fan rotation. In addition, the feedback accuracy of the motor is poor and cannot be detected in time. Fan problem, so the structure of the fan motor needs to be modified
