This document discusses a new patented design for the thinnest slim fan that is only 2.5mm thick and can operate at 10000rpm, making it suitable for use in small electronic devices like smartphones, tablets, and LED light bulbs. It has a simple structure with few components and uses a sintered bearing and embedded insertion molding of the bearing and housing. This new fan design improves reliability, reduces costs, and eliminates vibration compared to existing slim fan technologies. The target market for this new 2.5mm fan includes high-end smartphones, tablets, notebooks, and LED lighting with a total addressable market of over 2.5 billion units annually.
