"220V AC Cooling Fan" of various technologies have been quite mature, each design can only be improved with producers and improvement on this basis, if there is no major scientific discovery, driven by the short-term work in the form of fan and performance performance will not be a big change.
current, the research focused on all aspects of three directions:
1. Improved hydrodynamic design - modify, adjust or introduce new blades and frame design, and thus enhance the "220V AC Cooling Fan" Efficiency is always the demands of designers, the most fundamental way to improve;
2. extend the service life - Improved bearings, motor design, the use of new materials, the successful introduction of technology in various fields, in order to further extend the life of the fan, the design and manufacturer who racked rack their brains;
3. "220V AC Cooling Fan" to reduce operating noise - fundamental solutions to reduce friction and vibration, improve performance, and the same thing can be described as the first two, but due to the current "mute" more and more attention, some manufacturers began as a re-entered the center of the development plan, allocate research and development efforts.
