Abstract:
A populated printed circuit board cooling system comprising:a cold plate, formed of a heat transmissive material, with internal liquid circulating paths comprising: at least one header portion for connection to a liquid circulating source and return; and a heat absorbing portion for enclosing the internal liquid circulating paths, having at least one flat planar surface, the at least one header portion connected to a top or bottom of the heat absorbing portion, a top or bottom not connected to the at least one header portion being closed; and at least one personality plate, formed of a heat transmissive material, each having a flat side and a contoured side, wherein each contoured side conforms to a corresponding profile of a populated printed circuit board, and wherein, when the flat planar surface of the cold plate and the flat surface of the at least one personality plate are placed in contact and the side of the printed circuit board is in contact with the contoured side of the at least one personality plate, heat is transferred from components on the printed circuit board through the personality plate to the cold plate to be removed by a circulating liquid, and wherein each flat surface of the at least one personality plate and the flat planar surface of the cold plate are angled with respect to the printed circuit board.
