Holder and containment feature for multi-chip baseboard

An apparatus comprising:

• a chassis including a first plurality of cold plates;
• a first containment tray clamped to the first plurality of cold plates, the first containment tray including at least one first lip, at least one first access port and at least one first access chimney that provides access through the first containment tray to a cold plate from the first plurality of cold plates and access to at least one first fastener, the at least one access chimney being configured to extend higher than the at least one first lip such that the first containment tray retains fluid up to the at least one first lip when the at least one access port is sealed and the first containment tray is oriented horizontally, the first containment tray being clamped to the first plurality of cold plates using the at least one first fastener;
• and
• a first gasket adjacent to a perimeter of the at least one first access port, the first gasket being configured to create a seal between the first containment tray and the cold plate from the first plurality of cold plates.

A method for mounting a plurality of cold plates, comprising:

• clamping to a plurality of cold plates a containment tray including:
• at least one lip and at least one access port, the containment tray retaining fluid up to the lip when the at least one access port is sealed and the containment tray is oriented horizontally;
• for each access port, a gasket adjacent to a perimeter of the access port, the gasket creating a seal between the containment tray and a cold plate from the plurality of cold plates;
• and
• at least one access chimney providing access through the containment tray to a cold plate of the plurality of cold plates, each at least one access chimney providing access to a cold plate from the plurality of cold plates and extending higher than the lip when the containment tray is oriented horizontally;
• guiding the plurality of cold plates to a desired position on a baseboard using the containment tray;
• and
• attaching the plurality of cold plates to a plurality of heat-producing devices by inserting at least one fastener through the at least one access chimney and connecting a cold plate of the plurality of cold plates to a head-producing device of the plurality of heat-producing devices.
