Tiny Cooling Fan to withstand extreme environments

Most of the "Tiny Cooling Fan" are made of glass fiber reinforced plastic, this material is not only fire-resistant, but also by the certification of UL 94V-0 specifications. This plastic material is not only light, good cost, also suitable for mass production. And more importantly, the more complex components are easily made complicated shape, it is suitable to produce such as blades that need to optimize aerodynamic parts. A larger volume of "Tiny Cooling Fan", the frame may need to use a metal material (such as aluminum) to build. But if the size of the enormous "Tiny Cooling Fan" (diameter over 310 cm or more), then even the blade itself needs to be metal to produce.
