Micro Cooling Fan device methods are there?

"Micro Cooling Fan" means a method to solve the pump system and method of the same working conditions, working conditions illustrated fan unit is still the method now widely used. Fan P-Q curve showing the relationship between the energy and performance of the fan flow to the unit volume of gas supplied; "dota2雷竞技预测 " line P-Q performance curve showing the relationship between gas flow required per unit volume of the piping system and the flow of energy, which is curves of two different concepts. However, "dota2雷竞技预测 " fan unit, the two curves and interrelated, mutual restraint, the device is mass-balance conditions that result fan and piping; also a fan and piping energy balance results.
