Custom PC with 3 functions in 3U high

Issue

Noise reduction and improved heat dissipation. The integration of an air-water exchanger into a waterproof marine bay requires reducing the size of computers and improving the airflow inside the bay.

Bringing modularity to a very compact computer to fulfil different needs.

ECRIN Systems's solution

Evolution of a monolithic calculator in 4U 19 ” format to a 2U rack solution + 1U rack. The 2U rack integrates all the functions of a high-end PC, the 1U rack can hold different types of video converters and is also used as a tunnel for the rack ventilation.

Both racks are mechanically interfaced to finally offer a “LRU calculator” in 3U 19″ rack format.
