摘要：An assembly for mounting circuit cards having high power electrical and opticalalloy MCM chip devices installed thereon. The assembly has a central vertical coolantsupply pipe extending from a pump to a heat exchanger unit through a refrigeration unitseparated from the heat exchanger unit by circuit board mounting shelves equipped withelectrical and optical backplane apparatus interconnecting circuit cards mounted in themounting shelves. The heat exchanger unit has radiator fins separated by vanes extendedoutward from a hub of the unit and is interconnected by return pipes extending throughthe circuit card mounting shelves and terminated in the refrigeration unit which isconnected by a return pipe to the pump. Vent pipes connected with the heat exchangervanes extend from the heat exchanger unit into circuit card mounting shelves inengagement with mounted circuit cards to transfer heat generated by the engagedcircuit cards to the heat exchanger unit. The vent pipes are displaced to engage heatexchanger connectors terminating the vent pipes with circuit card heat sinks when thecircuit cards are installed in the mounting shelf to effect a transfer of heat generated bythe mounted circuit cards to the heat exchanger unit.
