Copper-Core 3.5 Inch Display Cooling Shell

A dedicated cooling shell for 3.5-inch fifth-gen displays, built around a central copper thermal core for maximum heat transfer efficiency. The ABS outer shell provides protection, electromagnetic shielding (via inherent dielectric properties), and ease of handling. Dimensions are calibrated for typical 3.5-inch display footprints, with tolerances held to ±1–3 cm to accommodate minor manufacturing variances across OEM modules. Package contains one silver ABS shell, one copper heatsink, and three soft-compression gaskets — all pre-sorted and labelled for quick identification during build. Fan integration follows standard 4-pin PWM conventions, with reinforced mounting posts capable of securing fans up to 40 mm square. Radiator compatibility covers standard 12×12 mm to 30×30 mm finned units, with provision for up to five in parallel configuration. The power button is tactically placed for thumb access and wired to a 2.54 mm pitch header — compatible with common SBC GPIO pinouts. Importantly, the display can be installed and operated without the upper cover, and radiator mounting remains fully functional in that state. Field-proven in automotive diagnostics tools, handheld medical UIs, and compact broadcast monitors — where display longevity depends on controlled thermal cycling rather than peak performance alone.
