【発明の名称】グロメット構造を備えた溶接熱交換器

Japanese Patent JP2002538411

A

A method of manufacturing a heat exchanger comprising a core assembly having a plurality of tubes connected by an array of fins, with ends of the tubes extending from the fin array on at least one side of the core assembly and resilient, polymeric grommets disposed around the tube ends. The heat exchanger includes a tank portion for receiving fluid entering or leaving the core assembly and a header portion having openings to receive the tube ends and grommets to create a sealed, fluid-tight tube-to-header joint. There is provided a reinforcing member across the opening of the tube ends extending from the tube end opening to the portion of the tube end around which the grommet is disposed without substantially extending into the fin array portion of the core assembly. The header portion comprises a substantially planar base having openings therein with side and end walls extending out of the plane of the base and connected by one or more fluid-tight welds to the tank portion. The side and end walls extend a distance sufficient to dissipate heat generated in making the welds and keep the heat generated from adversely affecting sealing ability of the grommets when the welds are made between the tank and header portion with the tube ends and grommets received in the header portion openings.
