Title: A Glimpse into the Innovations of Inventor Zhixin Li
Introduction
Zhixin Li is an esteemed inventor based in Hudson, NH, renowned for her remarkable contributions to the field of magnetic fluid technology. With a total of 17 patents to her name, she has consistently demonstrated her innovative prowess, leading to advanced solutions in various applications. Her work has not only pushed the boundaries of technology but also paved the way for practical uses in engineering and industrial sectors.
Latest Patents
Among her latest creations are two notable patents that exhibit her inventive skills. The first is the "Self-cooling ferrofluid seal." This innovative design includes a housing that features a housing case and an external pole piece integrated into the structure. The housing is equipped with multiple heat dissipating surfaces, while a magnetic circuit is formed within the housing in conjunction with the external pole piece. A notable component of this invention is a rotatable shaft, enhanced with fan blades, which is aligned coaxially within the housing. The core mechanism includes a quantity of magnetic fluid that forms a ferrofluid seal between the rotatable shaft and the external pole piece, ensuring efficient operation.
The second patent is the "Magnetic fluidic seal with improved pressure capacity." This invention comprises a magnetic assembly designed for a multistage magnetic fluid rotary seal. It involves a shaft paired with an annular permanent magnet and at least one pole piece, resulting in a radial gap between the shaft and the pole piece. The shaft and pole piece feature trapezoidal-shaped ridges in a non-contacting arrangement, thereby creating the radial gap. The flat top portion of the trapezoidal ridges faces the radial gap, while the tapered sides diverge away, enhancing the performance of the seal.
