Abstract: A circuit card unit comprising a memory card and attached heat exchanger comprising a thin, flexible, laminated strip of foil clad plastic, or wire mesh, affixed in thermally conductive contact to each card module and extended therefrom to facilitate removal of heat from the modules. In some embodiments, the exchanger strip extends from the modules on one side of the card to those of the other side in a self supporting, heat exchanger loop spaced over the memory card. In a somewhat more compact embodiment, the strip extends from modules on one card face, along the card itself, to the modules of the other card face. In a still further embodiment, the heat exchanger strip extends from the modules of the card to a heat sink such as the housing of the computer. Additionally, the heat exchanger strips may also function as a carrier for an identifying label printed on, or attached to, the planar surface of the strip.
