Title: CONDENSER HEADERS
Abstract:
A header (2, 3) for a condenser (1) of a vehicle air conditioning system has longitudinally opposed closed ends and is formed of an aluminium alloy material tube plate (6) and tank piece (5) brazed together. The tube plate (6) includes tube receiving openings (8) spaced along the length of a spanning portion (7) of the tube plate (6), the spanning portion (7) being integral with a substantially continuous peripheral rim wall (9a, b, c, d). The tank piece (5) cooperates with the tube plate (6) in a nesting relationship to form the header (2, 3), the tank piece (5) having an arcuate shell wall following a radius of curvature and including side portions (13) overlapping respective opposed side walls (9a, b, c, d) of the tube plate (6). Integrally formed with the tank piece (5) shell wall side portions are opposed end walls (14, 15) overlapping respective end rim walls (9c, 9d) of the tube plate (6). The opposed closed ends of the header (2, 3) is defined by the overlapping end walls of the tube plate (6) and end walls of the tank piece (7).
