The SI-38 is an ultra slim embedded system designed specifically for digital signage applications. Packing a fusion processor with discrete class graphics and multiple display outputs, its 25 mm thick chassis is nevertheless slender enough to disappear into the tightest spaces behind displays. The system is built around a die-cast aluminum thermal frame that serves simultaneously as the entire system’s structural backbone for thermal conduit, airflow divider, HDD rail, EMI shield and mounting bracket. To ensure long-term reliability with a minimum acoustic footprint, the cooling airflow is segregated from the electronics to keep contaminants out.
