Herstellungsverfahren für Flachrohre sowie Walzenstrasse zur Durchführung des Verfahrens.

摘要

#CMT# #/CMT# The method involves providing a strip with wall parts (a, b) and an inner part (c) that is formed with ripples on a roller line fitted with a pair of rollers, where the strip runs and is formed in a longitudinal direction by the rollers. The inner part is attached between the wall parts, and a closing of a flat pipe is executed. Rarefaction lines are arranged with a distance running in a longitudinal direction of the strip. A wave crest and a wave trough lying in the rarefaction lines are made. The rarefaction lines are formed in parallel lines. #CMT# : #/CMT# An independent claim is also included for a roller line for executing a method for manufacturing a flat pipe. #CMT#USE : #/CMT# Method for manufacturing a flat pipe that is utilized in a heat exchanger of a motor vehicle by a roller line (all claimed). #CMT#ADVANTAGE : #/CMT# The rarefaction lines are arranged with distance running in longitudinal direction of the strip, where the wave crest and the wave trough lying in the rarefaction lines are made, thus simplifying the manufacturing of the flat pipe and hence reducing investment funds for the heat exchanger. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a flat pipe, in which an inner part is inserted. a, b : Wall parts c : Inner part 1 : Narrow side 4 : Inverted longitudinal edges 10 : Gradation.
