STS Defence was tasked with undertaking a feasibility study into removal of wild heat from a cabinet containing mission-critical equipment aboard a UK submarine using a supply of chilled water without increasing the ambient temperature within the compartment.
The study concluded that the level of heat removal was possible and proposed a cabinet design would provide the required temperature control using the boat’s chilled water supply with a bespoke heat exchange and fan matrix.
STS Defence was then contracted to design, manufacture and test a single 34U aluminium cabinet solution which met IP54 standards and incorporated both red and black components, associated cable loom management and power supplies as well as a unique automatic transfer switch connected to the boat’s primary and secondary supplies to provide uninterrupted power to the equipment.
Extensive EMC and environmental testing was undertaken which culminated in a successful demonstration where cool air was driven by forced convection through the equipment. The uninterrupted power operations to essential components was also successfully demonstrated.
This was a complex, challenging technical requirement resulting in an equipment enclosure that was designed and built to meet military maritime environments in above and below surface platforms.
