Core Insights - Apple has recently been granted a highly innovative patent focusing on a lightweight, multi-layer fan component for the MacBook Pro, which is expected to significantly reduce the laptop's weight while maintaining structural integrity, cooling performance, and electrical connections [1][3] Group 1: Patent Highlights - The patent features a unique composite base structure design that rethinks the entire fan base rather than just improving the fan blades, combining metal layers with lightweight core materials such as plastic, carbon fiber, and fiberglass [3] - This design ensures rigidity and prevents deformation during user operations, reducing the risk of fan blade contact with the fan cover, thereby minimizing noise and wear [3] - The core layer may include printed circuit boards (PCBs) for internal wiring, reducing reliance on external flexible cables and connectors, leading to a more streamlined and efficient internal structure [3] Group 2: Performance Improvements - The separate component design allows for thinner fan covers and larger blade gaps, which not only reduces friction noise but also improves airflow consistency and enhances cooling efficiency [3] - An additional metal layer increases thermal conductivity, and a customized thermal expansion coefficient helps manage heat more effectively, ensuring device stability during high-load operations [3] - The conductive pathways within the fan base reduce dependence on external cables, with installation standoffs serving as low-resistance points for power transmission, further optimizing the overall design [3]
