Abstract: A tube and fin type heat exchanger core made up of unique and identical plate strip structures having formed extrusions, the extrusions nesting when the plates are stacked to form the tubes and the portions of the plates between the extrusions forming the fins. The extrusions form trough-like projections with a number of holes in the bottoms of the trough-like projections to permit the flow of fluid between the plate structures. The walls of the projections have offset portions to serve as spacing means between the plates. A slight crimp or bend is provided in the plate portion between each extrusion to facilitate the assembly of the plate structures regardless of small deviations in the spacing dimensions between extrusions.
