Document Type and Number:
WIPO Patent Application WO/1997/012192
Kind Code:
A1
Abstract:
The invention relates to a water tank for a radiator system or a collecting pipe for a heat exchanger, and a method and a device for the production thereof. The water tank or the collection pipes according to the invention comprise a pipe section having a cross-section of a D-shaped profile with a flat side, and slots with peripherals linings for holding radiator flat tubes are positioned in the flat side thereby increasing the strength, in particular the fatigue strength, which allows the introduction of radiator flat tubes into the slots. The invention also relates to a method and a device for producing the inventive water tank or collecting pipes from a continuous sheet metal strip.
