Title: Innovations by Fumihiro Morikawa: A Glimpse into His Patents
Introduction
Fumihiro Morikawa, an inventive engineer based in Yonago, Japan, has made significant contributions to the field of cooling technologies through his innovative patents. With a total of four patents to his name, Morikawa has focused on enhancing the efficiency and performance of heat sink fans, which are crucial in various electronic applications.
Latest Patents
One of Morikawa's latest innovations is a sophisticated heat sink fan. This design features a fan motor equipped with blades, encased in a rectangular upper casing that securely holds the motor. The lower casing, which is fixed to the upper casing, has a bottom portion along with fin dissipating fins that are erected perpendicularly from its four side edges. What sets this invention apart is the mechanically interlocking mechanism utilized to combine the upper and lower casings. This mechanism employs a combination of pawls and receiving portions, projections with inflated portions and cavities, as well as hooks and engaging grooves. Morikawa's design also enhances the heat dissipation efficiency by integrating fin portions throughout the casing, excluding the fan motor and blades.
Furthermore, he has developed an advanced fan motor characterized by a configuration featuring a pair of ball bearings located near each end of the bearing race's inner side. To ensure the proper axial positioning of the ball bearings, Morikawa has innovatively placed a plurality of projections circumferentially around the center portion of the bearing race. Additionally, low-profile projections are strategically formed between these neighboring projections, contributing to the effective support and positioning of the ball bearings.
