Title (EN) TUBE JOINING
(FR) ASSEMBLAGE DE TUBES
Abstract:
(EN) Joining thin heat exchanger tubes to manifold header tanks is improved by extruding thick tubes having channels or microchannels. Tube material is removed from spaced areas of central portions, leaving finned thin heat exchanger central portions and thicker header portions. The tubes are curved, twisted and tilted. The tubes are aligned horizontally, vertically or angularly, and the header portions are welded together. Tube material is removed from the ends of the header portions to form end faces with projections extending from the end faces and surrounding the channels or microchannels. End plates with openings to receive the projections are attached and sealed to the projections and end faces by welding or brazing. The face plates are attached and sealed to openings in the header tanks by welding or brazing. Tube ends are flattened. Rings are added. Ends and rings are friction welded, avoiding areas around channel openings, and polished.
(FR) L'assemblage de tubes d'échangeur de chaleur minces aux réservoirs de tête de collecteur est amélioré par l'extrusion de tubes épais ayant des canaux ou des microcanaux. Le matériau de tube est retiré de zones espacées de parties centrales, laissant des parties centrales d'échangeur de chaleur mince à ailettes et des parties de tête plus épaisses. Les tubes sont incurvés, torsadés et inclinés. Les tubes sont alignés horizontalement, verticalement ou angulairement, et les parties de tête sont soudées ensemble. Un matériau de tube est retiré des extrémités des parties de tête pour former des faces d'extrémité avec des saillies s'étendant à partir des faces d'extrémité et entourant les canaux ou les microcanaux. Des plaques d'extrémité dotées d'ouvertures destinées à recevoir les saillies sont fixées et scellées aux saillies et aux faces d'extrémité par soudage ou brasage. Les plaques de face sont fixées et scellées à des ouvertures dans les réservoirs de tête par soudage ou brasage. Les extrémités des tubes sont aplaties. Des anneaux sont ajoutés. Les extrémités et les anneaux sont soudés par friction en évitant des zones autour des ouvertures de canal et polis.
