Abstract

A heat exchanger 40 for a gas turbine engine (10, fig 1) comprises a structure including an enclosed fluid cavity 58. The structure has opposing sides 46, 48, and a set of fins 68 is supported on one of the sides 48 and arranged outside the cavity. The set of fins 68 includes rows of discrete chevron fins (70, fig 5) separated by periodic gaps (72). In use, the heat exchanger is arranged in a gas turbine engine 10 comprising core (12) supported relative to a fan case (22), a fan duct (26) is provided between a core nacelle (20) and the fan case. The core includes a compressor section and a bleed cavity 28 is provided within the core 12 and is in fluid communication with the compressor section. The side of the heat exchanger with the set of rows of fins with periodic gaps is exposed to the bleed cavity 28. The fins may be trapezoidal shape with a leading (74) and trailing (76) edge. Fins may be provided on the other side 46 without periodic gaps.
