Holder and containment feature for multi-chip baseboard
A system and apparatus are provided for containing leakage in a cooling system, thereby preventing the leakage from contacting sensitive electronic devices. A containment tray is configured to cover the surface of one or more cold plates and the electronic devices beneath. The containment tray includes an access port in the base of the containment tray for each cold plate. Hydraulic fitting connections on each cold plate pass up through the access ports and are connected to a coolant supply system. The containment tray is clamped to the cold plates with the gaskets creating a seal between the cold plate and the containment tray. Thus, the containment tray is positioned to collect leakage from the coolant supply system connected to an above the cold plates and electronic devices beneath.
