The characteristics of the cooling fan
in a space within the device or component, the fluid impedance, formed by smooth convection of the fluid method.
1, the system impedance is small: features must be air volume of fan, wind pressure is small.
2, system impedance, small features must be air volume of fan, wind pressure is big. Wenling chi automotive air conditioning manufacturing co. , LTD. Is specialized in raw oil bearing, ball bearing, hydraulic cooling fan
the fan performance curve is used for table not fan performance curve of it or not, such as system impedance line collocation, can accurate selection of fan
