A temporary assembling unit for a heat exchanger core including a pair of parallel feed shafts (31,33) placed facing each other in a predetermined spacing, comprises: spiral tube guide grooves (31a,33a) for guiding ends of a tube (35) of the heat exchanger; and spiral fin guide parts (31b,33b) for guiding ends of a corrugated fin (37) of the heat exchanger, the spiral fin guide parts (31b,33b) being disposed between the tube guide grooves (31a,33a); wherein an outer diameter (R1) of the fin guide part positioned in a supply section of the corrugated fin is smaller than an outer diameter (R2) of the tube guide groove. <IMAGE> |
