220V AC Cooling Fan design selection proposal

"220V AC Cooling Fan" scientific selection will affect the quality of the product must be fully taken into account reliability, economy and feasibility of the product. And this is why you want to understand the reasons for fans of various characteristics.
Voltage affect the price and design
Affect the cooling effect of wind, noise, price (consider hydrostatic, balance, environmental temperature, temperature control, etc.)
"220V AC Cooling Fan" size affect the price, noise (need to consider the installation to size, etc.)
Life affect the price, reliability (need to consider the design life, the environment, etc.)
"220V AC Cooling Fan" bearing the impact of price, reliability, should fully consider the actual use of the environment (to be considered high temperature, humidity, vibration, dust, dust, noise, etc.) in the design selection, if there Supplier Inter ventional fit considering various proposals will make the design simplification, but also did not like a lot of engineers can not find or design a shortage of components, thereby shortening the development cycle, reduce costs and improve reliability.
