Raspberry Pi Zero 2 W Active Cooling

The Raspberry Pi Zero 2 W Active Cooling project manages thermal output in compact computing setups by combining passive and active cooling elements integrated via a custom printed circuit board (BE_SecureFrame.brd). The Raspberry Pi Zero 2 W generates thermal energy during intensive computational and graphical processes, which can lead to thermal throttling and reduced processing performance. To mitigate this, passive heat sinks are mounted directly to the main processor to absorb and dissipate initial heat. Simultaneously, a dedicated cooling fan provides forced-air convection to continually clear warmed air away from the board. Electrical power and control for the fan are routed through a custom-designed PCB featuring a JST connector, ensuring a secure, low-profile connection that integrates neatly with the single-board computer's footprint. Design files for the custom PCB are prepared and modified using Autodesk Eagle, allowing undergraduate engineering students to understand how custom hardware shields and breakout boards interface physically and electrically with compact computing hardware. By combining a physical frame for secure mounting, heat sinks for conduction, a fan for forced convection, and a custom PCB for power distribution, the system maintains optimal operating temperatures without requiring bulky aftermarket enclosures.
