What is the system impedance commonly used in cooling fans? What is the effect of understanding the system impedance? In general, we understand the main parameters of the cooling fan only some of the cooling fan water main parameters, basically there is no said system software impedance of the term. System Software impedance is the friction resistance of cyclone separator in mechanical equipment. The smaller the frictional resistance, the higher the exhaust gas volume. As long as we measure the impedance inside the device, we can use the impedance to determine the point of action. What's the action point? The point of intersection of PQ characteristic curve and Fan System impedance curve is taken as the point of action. Only when the fan can meet the precondition of the heat dissipation of the machine and equipment, can the working position be defined according to the said method, and the Fan with high cooling performance can be selected. If the working point is determined according to the system impedance value, 1. Make the fan selection standard more definite, shorten the fan selection time 2. You can choose a fan with low noise and power consumption. 3. Improve the layout of components and components to reduce system software impedance thank you for reading.
