Abstract
A heat exchanger for a gas turbine engine comprising a compressor, a combustor and a turbine. The heat exchanger comprising alternating hot and cold channels. Compressed air from the compressor flows through the cold channels and exhaust gas from the turbine flows through the hot channels. Each cold channel comprises first and second opposing surfaces conveying compressed air along a first path. Each cold channel comprises rows of vortex generators and pin fins extending from the first or second surfaces along the first path. The rows extend substantially perpendicular to the first path. Each hot channel is defined by a first and second opposing surfaces conveying exhaust gas along a second path substantially perpendicular to the first path. Each hot channel comprises rows of vortex generators and pin fins extending from the first or second surfaces along the second path. The rows extend substantially perpendicularly to the second path.
