ABSTRACT:
A method of manufacturing an elongate fluid conveying tube that includes starting from a blank of metal material, wherein the fluid conveying tube is adapted to be mounted in a vehicle cooler and comprises at least two internal elongate ducts. The method of manufacturing the tube includes forming a projecting surface structure on a portion of the surface of the blank. The method also includes defining a substantially flat web portion between two upright edge portions that are formed along two opposite edges of the blank. Additionally, the method involves forming the ducts such that the edge portions are situated perpendicular to the web portion and the outer faces of said edge portions are brought into abutment against each other and against the web portion for defining said ducts.
