1. A system for cooling an electronics enclosure, comprising:a chassis assembly including:
an alignment frame supporting respective first and second circuit boards separated by a first cavity, each of the first and second circuit boards being connected to and arranged perpendicularly to the alignment frame; and
a planar base frame arranged generally perpendicularly to the alignment frame and including a support surface supporting the first and second circuit boards, the planar base frame including an elongated slot formed therein, the elongated slot defined by an open aperture passing perpendicularly through the planar base frame; and
a cold plate assembly including:
a base unit, the base unit including a planar support surface; and
a planar first cold plate member connected to perpendicularly extend away from the support surface of and conductively cooled by the base unit, the planar support surface supporting the first cold plate member, wherein the chassis assembly and the cold plate assembly are configured for slidable engagement with the planar base frame and the planar support surface being generally parallel so that when the chassis assembly and the cold plate assembly are slidably engaged, the first cold plate member is slidably displaced perpendicularly through the elongated slot and through the planar base frame and is received in the first cavity such that the first cold plate member is in direct contact with both the first and second circuit boards and the planar base frame is seated on the planar support surface.
