ABSTRACT:
A liquid cooled heat exchanger particularly adapted to cool heat sinks of an electrical power supply for large electronic systems. The heat exchanger has thin flexible walls. Pressure of the coolant within the heat exchanger assures a positive mechanical contact between the heat exchanger and the heat sink, one that can accommodate changes in dimensions of the heat sink or heat exchanger and a lack of planarity of the surfaces of the heat sink without increasing the thermal impedance between the liquid in the heat exchanger and the heat sink. Fluid flow within the heat exchanger is controlled so that heat transfer efficiency between certain areas of the flexible walls and the coolant is maximized, which areas are proximate to the heat sources mounted on the heat sink.
