Abstract
A heat exchanger assembly formed from primary structure comprising core (10) comprising a multiplicity of primary fluid sections (15) and a plurality of secondary fluid sections (20) wherein a respective primary fluid section (15) is located adjacent to a respective secondary fluid section (20) with each primary fluid section (15) being substantially parallel to each secondary fluid section (20) characterized in that each primary fluid section (15) is bounded by a peripheral wall (12) and that each secondary fluid section (20) include a first array of fins (18) extending away from the peripheral wall (12) of one adjoining primary fluid section (15) and a second array of fins (19) extending away from the peripheral wall (12) of another adjoining primary fluid section (15) wherein an individual first fin may extend between each adjacent second fin in interleaved relationship wherein the surface area of each secondary fluid section is substantially greater than the surface area of each primary fluid section.
