With the rapid development of the information industry all over the world and the emergence cloud computing, the demand for the storage device is becoming greater. Therefore, the industry of heat emission products will be the key of development, especially the heat emission with low power consumption and high efficiency. The famous manufacturer in Taiwan released the super green fan. The super green fan becomes one of the most advanced devices in the related field, because it is designed with the goal of high efficiency, low power consumption, low vibration, low noise and long service life.

The new device integrates five innovative technologies. Apart from the characteristics of low power consumption and low vibration, the device uses smaller output ripple to reduce the vibration, making the service life long. Moreover, the inner rotor motor construction is applied in this device, fixing the fan outside of the axis. Therefore, the burden of the fan will be decreased, which will make the noise low. The special design of the super green fan shows the high performance of the motor, which not only lengthens the service life of the device, but also extends the life circle of the system.

In order to produce the high quality heat emission fan, the design of the fan palms must be improved accordingly. According to the accurate estimation of fluid dynamics theory, the area of fan palms is expanded, while the volume of the motor is reduced. Moreover, the integration of the closed motor and inside compression plate optimizes the heat emission efficiency. This design not only provides the system more pressure and air to meet the heat emission demand of the computer, but also cut off the disturbance. In order to improve the heat emission efficiency, the heat can be transmitted by the metal shell of the motor. This design can lengthen the life of bearing and fan palms. People will not worry about their computers when they are working twenty four hours a day with the new heat emission device. With the concept of environmental protection, the heat emission fan with high efficiency and low power consumption will be more popular in the future. More researches need to be taken to pursuing the innovation of the products. The related integrated circuit is 2SK2993.
