PROBLEM TO BE SOLVED: To prevent both ends of a corrugate fin easily surely from getting on a fin guide part in the supply of the corrugate fin in a temporary assembling device for temporarily assembling a heat exchanger core by disposing a tube and the corrugate fin alternately. SOLUTION: Tube guide grooves 31a, 33a to guide an end of the tube 35 are spirally formed on a pair of feed shafts 31, 33 disposed in parallel opposedly at a predetermined interval, while fin guide parts 31b, 33b to guide an end of a corrugate fin 37 between the tube guide groves 31a, 33a are formed spirally in a temporary assembling device for a heat exchanger core. The outer diameter R1 of the fin guide part 31b, 33b located in a supply part 39 of the corrugate fin 37 is formed smaller than the outer diameter R2 of the tube guide grooves 31a, 33a. |
