Abstract

A heat exchanger includes a stack (106) of flow conduits. Each flow conduit is configured to conduct a fluid. Parting sheets (124) separate adjacent flow conduits in the stack, providing heat transfer between them. Each of the flow conduits includes vanes (110, 112) extending along a vane path and between top and bottom parting sheets. The vanes are separated from one another, thereby creating flow channels. Each flow conduit also includes a plurality of flow modifiers (136), each adjacent to a corresponding leading edge of a corresponding vane, so as to cause a disrupted portion of a fluid flow to be incident upon the corresponding leading edge. Each of the flow modifiers includes an aerodynamic portion and a gap portion. The aerodynamic portion extends from at least one of the top and bottom parting sheets. The aerodynamic portion does not connect the top and bottom parting sheets due to the gap portion.
