Abstract
Cold plates, permanently plumbed into card cage, cool circuit boards that are equipped with personality plates to improve thermal transfer. The personality plates have a contoured surface that is the complement of the circuit board's landscape. The personality plate made of heat transmissive material therefore contacts each heat generating component, regardless of its height. The opposite surface of the personality plate is flat, and, when installed with the circuit board in the card cage, lies parallel to the surfaces of the cold plate. A card ejector applies force on the entire board bringing the flat surfaces into intimate contact for excellent heat transfer. The assembly of circuit board and personality plates is augmented by interposing thermal interface material at each contact surface and fastening this assembly into a unit.
