Abstract
An integral fin/tube combination of extruded aluminum wherein the fins are shredded into parallel radial strips which are bent into alternately upwardly and downwardly peaked configurations. Shredding may be accomplished by means of a die set.
Claims7
A method of manufacturing an integral extruded fin/tube combination wherein the tube forms a fluid conduit and the fin effects a thermal exchange between fluid in the tube and the surrounding environment comprising the steps of:
- extruding a relatively thin-walled tubular body having at least one radially extending and relatively thin-walled fin integral with the body, and thereafter splitting the fin over its entire length into a plurality of narrow and radially parallel strips which are integral only at the radial extremity thereof and alternately bent into reversely similar peaked configurations exhibiting substantial radial compliance as well as axial bunching and spreading capability whereby the tube/fin combination is both radially dimensionally conformable and easily bent.
A method of manufacturing an integral extruded fin tube combination wherein the tube forms a fluid conduit and the fin effects a thermal exchange between the fluid in the tube and the surrounding environment comprising the steps of:
- extruding a relatively thin-walled tubular body having a plurality of circumferentially spaced radially extending thin-walled fins integral therewith and thereafter splitting the fins over substantially the entire lengths thereof into relatively narrow radially parallel strips which are integral only at the radial extremities thereof and which are alternately bent into reversely similar biplanar peaked configurations exhibiting substantial radial compliance as well as axial bunching and spreading capability whereby the tube/fin combination is both radially dimensionally conformable and easily bent.
