ABSTRACT:
A method and brazing fixture are provided for passing a plurality of heat exchanger components through a brazing furnace to provide a heat exchanger for use in a motor vehicle air conditioning system. The brazing fixture includes a reusable brazing tray having a flat planar surface for securing the heat exchanger components thereto, in alignment for passing through the brazing furnace. The heat exchanger components include refrigerant flow tubes and fin stock, which are placed alongside of the planar surface, with the planar surface extending substantially along the full length of the fin stock to prevent high fin. Circulation ports extend through the brazing tray in a honeycomb pattern along the planar surface, for passing heated gases within the brazing furnace between the fin stock and flow tubes. The planar surface of the brazing tray is formed from a material to which the heat exchanger components will not braze, and which will not tend to stick to brazing flux.
