A condenser for use in an automobile air conditioner, which includes a pair of header pipes (1) each consisting of a tank portion (2) and an end plate (3); a plurality of parallel flat tubes (14) extending between the header pipes for supporting coolant flows; the end plate being continuously outwardly curved and joined to the tank portion such that inside surfaces of opposite joint edges (2a) of the tank portion overlap outside surfaces of opposite joint edges (3a) of the end plate, whereby the tank portion reinforces the end plate to withstand high pressures of the coolant flows. The flat tubes are brazed to the header pipes such that opposite ends of each flat tube are brought so closely to the joint edges that there is only a minimum clearance that is able to prevent brazing material from entering the flat tube, whereby the tank portion is minimized. |
