Abstract
A method for forming a heat exchanger is disclosed. The method includes the steps of forming a plurality of generally planar plate members from a sheet of material, each of the plate members being connected to an adjacent plate member by a deformable link. The method further includes forming a plurality of tube members by folding the plurality of plate members at the deformable links, inserting a fin member between adjacent tube members, and compressing the plurality of tube members and fin members under a predetermined load to form a heat exchanger core. The method also includes the steps of bending the folded deformable links against the core and brazing the core at a predetermined temperature. A heat exchanger manufactured according to this method is also disclosed.
