Fujifilm Patents Advanced Cooling System for 8K Mirrorless Cameras
Fujifilm has filed a patent for an innovative cooling system designed to tackle overheating issues in its compact mirrorless cameras, particularly during demanding 8K or high-fps recordings. The patent reveals an integrated airflow and heat dissipation system, positioning Fujifilm alongside Canon and Sony who have also explored internal cooling architectures. The system aims to maintain data rates without throttling or stopping, a common issue in hybrid cameras. The design targets CFexpress cards, known for heating up under sustained high-bitrate recording. It focuses on cooling the recording unit, featuring a finned heat sink for the controller board and a graphite/metal sheet for the card slot. Different fin orientations and spacings are used to avoid turbulence and interference between heat flows. If implemented, this design could significantly improve heat management in Fujifilm's smaller X-series cameras, enabling them to handle true long-form, high-data-rate video without the need for external fans. The patent suggests Fujifilm is preparing its compact cameras for more demanding video workloads.
