  • High performance compact heat exchanger
    Publication number: 20100038056
    Abstract: A high performance compact heat exchanger includes a base plate with evaporator channels for cooling a heat source adjacent to the base plate. A condenser is connected to the base plate and includes fins with channels therein for the coolant. A pump delivers the coolant to the evaporator channels of the base plate after passing through the fins of the condenser.

  • Distributed transmit/receive integrated microwave module chip level cooling system
    Patent number: 7548424
    Abstract: A radar transmit and receive integrated microwave module with conductively cooled condenser side rails and one or more vacuum brazed fluid distribution manifold cold plates in fluid communication with the side rails. There are one or more transmit and receive modules on a cold plate. Each module includes a coolant input and a coolant output. One or more gallium nitride monolithic microwave integrated circuits are within each transmit and receive module and each include a micro heat exchanger in fluid communication with the coolant input and the coolant output of the transmit and receive module to directly cool the gallium nitride monolithic microwave integrated circuit.
