BRAZING JIG ASSEMBLY FOR HEAT EXCHANGER AND METHOD OF MANUFACTURING HEAT EXCHANGER USE OF THE SAME

摘要

PURPOSE: A brazing-jig assembly for a heat exchanger and a method of manufacturing a heat exchanger using the same are provided to prevent flux trace from appearing on a tube since a core does not make contact with a second support clamp in brazing. CONSTITUTION: A brazing-jig assembly for a heat exchanger consists of a temporary assembling unit(20) and a tray(100). The temporary assembling unit consists of a pair of header pipes and a core. The header pipes are arranged to be spaced apart in a horizontal direction. The core comprises a plurality of tubes and a plurality of heat radiating fins(12). The tubes are laminated to be spaced apart between the header pipes. The heat radiating fins are arranged between the tubes. The trays are arranged on the lower parts of the heat exchanger and the temporary assembling unit. The tray makes the temporary assembling unit or the core spaced apart from the floor.
