| description | A folded multi-passageway flat tube is disclosed, which is made from a flat sheet metal strip and has folded webs and a longitudinal seam. Through-openings for improving the heat transfer and for generating transverse flow are provided in the folded webs. The through-openings are advantageously made by punching in the flat sheet metal strip, that is to say before folding, and are made congruent after folding. These folded multi-passageway flat tubes are preferably used for refrigerant condensers in motor vehicle air-conditioning systems. |
