220V Cooling Fan Design considerations must

"220V Cooling Fan" Considering the aerodynamic, streamlined airflow factors and aircraft design aesthetic factors. Ray fan made of cast aluminum and chrome or nickel-plated brass, has a tapered fuselage, tail tapers gradually shrink to the tip. In its pointy tail wing also with balance, making it very similar to the real rocket. In addition, "220V Cooling Fan" is also designed with two or three helical blades cast aluminum, used to simulate the front propeller aircraft appearance, in order to highlight this fan of aviation style. "220V Cooling Fan" represents the second half of the sweeping aerodynamic design trends booming throughout Europe and the United States on the 20th century fan market. This extensive use of design trends propeller-shaped motor casing and bullet-shaped blade, affecting many manufacturers of home fans, and continues to this day.
