Description of the invention: [Technical field of the invention] The present invention relates to a fan capable of improving wind pressure and flow characteristics, in particular, the _-subtractive amplification unit will be placed in the field, and the signal is transmitted to the -micro control unit. After the _ micro-control solution, the fan is turned to increase the wind pressure and flow. [Prior Art] Due to the rapid advancement of technology, various electronic products have been given more functions to enhance the use value. Due to the increased functionality, it is necessary to add more components or parts to the system of Silicon Valley. In the system, the above components or parts not only increase the density, but also increase the heat density. Therefore, heat sinks are needed to help them dissipate heat. Generally, a cooling fan is preferred because of the scale flow generated by the heat sink. The way the heat inside the system is taken away to achieve heat release. When the fan generates fluid to flow into the system, the flow path is blocked by too many components or parts, and the heat dissipation effect is greatly reduced. Therefore, it is necessary to increase the flow rate and wind pressure of the residual fan, and the general practice is Two kinds: one is to increase the fan speed; the other is to change the fan blade structure, but the disadvantage of increasing the fan speed will cause electrical consumption (such as: miscellaneous power), resulting in more resources waste. In addition, please refer to Figure 1 for the fan characteristic curve. The figure shows that the fan is used in systems with fewer components or parts, and the density is sparse. When the fan turns the temple, the fluid is flowing. The fluid in the path of its flow will encounter the surface of the internal parts of the system, its impedance will limit the free flow of fluid, and thus the loss of the money, and the loss of air volume is 200826829 is the system impedance curve βΐ (System Impedance Curve) And the internal parts or components of the system are small and the density is sparse, and the system impedance curve βι is low. The wind lion is the TKAir Volume Curve. The intersection point of the two is The system operates the operating point PKGperatingPonint), and its week_ is the operating area Q. In the operating area Q, it is the operating performance that the fan can exhibit in a system with a sparse density. Please also refer to Fig. 2, which is a fan that is used to increase the speed and current of the fan. (4) Depending on the towel, it is a __like wind wire used in a large number of components or parts, and a system with high density. When the fan rotates, the fluid flows in the path of its flow, and it will encounter the internal parts of the system. Its impedance will restrict the free flow of the fluid, which will cause the loss of wind pressure. The loss of air volume is The system impedance curve BUSystem Impedance Curve), while the internal parts or components of the system are high in density, the system impedance curve B1 is higher, and the fan structure is measured by the wind tunnel. The curve is the fan characteristic curve T1 (Air ν〇1· The intersection of the two is the system operating point pi (〇perating her, and the surrounding area is the operating area Q, which is the operating efficiency of the fan in the operating area Q) to dissipate the heat inside the system. It is necessary to improve the shortcomings of the prior art. [Summary of the Invention] The main purpose of the invention is to provide a fan, which is to be transmitted after the amplification process is performed. The control signal is sent to the driving circuit unit to the micro control unit, and the driving circuit unit is controlled according to the control signal to rotate the fan to achieve heat dissipation and energy saving.
