Heat exchanger for a gas turbine engine

Abstract:

A heat exchanger for a gas turbine engine includes a core configured to heat or cool a fluid flowing therethrough. The core, in turn, extends along a lateral direction between a first end of the core and a second end of the core and the core defining one or more fluid passages. Furthermore, the heat exchanger includes a manifold coupled to the first end or the second end of the core. The manifold, in turn, includes a manifold wall at least partially defining a fluid chamber in fluid communication with the one or more fluid passages. Moreover, the manifold further includes a feature permitting thermal expansion or thermal contraction of the manifold wall relative to the heat exchanger core.
