ABSTRACT:
A circuit card having the capability for the high-density packaging of electronic components thereon for use in high power-density card racks in computer and other electronic and avionic systems. The card has an all metal construction with an elongated planar body portion for the mounting of electronic components on the opposite sides thereof and has a heat pipe located along the edges of one elongated side and the two ends. A connector for making the required electrical connections to the electronic components is provided along the edge of the second elongated side. Edge tabs on the ends of the card permit the card to be installed into a card rack in electronic equipment. The elongated portion of the heat pipe serves as the evaporator region thereof and the two end portions act as the condensing regions. In operation, heat from the components on the card is conducted into the evaporator region of the heat pipe and is transferred to the condensing region thereof where it passes by conduction into the cooling system of the card rack.
