Abstract:
An adjustable pitch heat exchanger comprising:a pair of spatially separated manifolds, each manifold in said pair having an internal curved surface, and having a facing longitudinal opening;a plurality of manifold inserts that are at least partially conformable with the internal curved surface and that are sealingly attachable to one of said pair of spatially separated manifolds, juxtaposition of adjacent inserts providing a plurality of tube apertures defined between adjacent inserts aligned with said longitudinal openings;a plurality of tubes extending transverse to said spatially separated manifolds, one end of each of said plurality of tubes being received in a respective one of said tube apertures provided by said inserts attached to one of said pair of spatially separated manifolds and sealed thereto, the other end of each tube being received in a respective one said tube apertures provided by said inserts attached to the other of said pair of spatially separated manifolds; andwherein the length of each of said inserts being selectable to produce a desired pitch of said tubes.
