Research output: Patent


Improved heat exchangers according to several embodiments are provided. The heat exchangers provide improved heat transfer for air flow in wet and dry operating conditions, while minimizing pressure drop across the heat exchanger in some applications. According to one embodiment, an improved heat exchanger includes a plurality of metal foam fins between adjacent heat exchange conduits, the heat exchange conduits being arranged parallel to each other to define parallel flow paths between an inlet header and an outlet header. The metal foam fins occupy a cross-flow region between adjacent conduits, the fins having a fixed angular orientation or being rotatable in unison to vary the thermal capacitance of the heat exchanger.
