Method of making a parallel flow condenser with lap joined headers

摘要

A parallel flow condenser is provided for use in an automotive air conditioner. The parallel flow condenser has tubular headers formed by taking a metal sheet, cutting slots therein for receiving parallel flow tubes, rolling the metal sheet to form the tubular header with opposing edges which are lap joined, and cutting slots into the header for receiving the baffles. The condenser is then assembled and placed within a brazing furnace to sealingly secure the condenser assembly together.
