A heat exchange module for use with a plurality of similar modules to form a recuperator for use in an gas turbine engine. The module has a center section with a generally rectangular cross-sectional shape, a first side section with a generally triangular cross-sectional shape, and a second side section. The module can be combined with other modules to form a polygonal recuperator with a center aperture.

An annular heat exchanger comprising: a plurality of rectilinear heat transfer portions, each portion having a first fluid inlet side, an opposite first fluid outlet side, and two lateral sides; means for conduiting a second fluid into and out of said heat transfer portions comprising lateral side portions located between heat transfer portion lateral sides and having a general triangular shape with second fluid inlet and outlet conduits therein, said first fluid inlet sides defining a center aperture and said lateral side portions being substantially separate from said center aperture such that said first fluid inlet sides form substantially the entire first fluid inlet area to the heat exchanger and the location of the lateral side portions allow the heat exchanger to have a relatively small size.
