ABSTRACT:
A cross-flow heat exchanger comprising according to a preferred embodiment a shell formed of two concentric cylinders providing an annular space. A number of tubes and baffles are arranged in the annular space such that one fluid flows through the tubes in a helical fashion in the annular space and the second heat exchange fluid flows in a counter helical path in such annular space across the tubes, constrained by the baffles in such annular space. In another embodiment cross-flow is also achieved using spirally shaped tubes and spirally shaped baffles.
