The added expense of providing fixtures for holding side pieces in heat exchangers in place during assembly is avoided in a heat exchanger having a core with at least one row of spaced, parallel, straight runs (12-20); (70-86) of flattened tubing (10) which includes first and last spaced side runs (12), (20); (70), (92) which define an associated side on opposite sides of the row. Fins (36), (62) bridge the spacing between each of the plurality of runs and extend oppositely from outwardly facing sides (42), (44); of the first and last runs (12), (20); (70), (92); and are bonded to the tubing (10). A pair of side pieces (46), one for each side of the row, are provided and are hooked on the associated ends of the first and last runs (12), (20); (70), (92). The side pieces (46) are self-fixturing by reason of being hooked on the tubing.
