摘要： A heat exchanger, bent flat tube and method for bending of flat tubes for heat exchangers. The flat tube is initially formed as a straight flat tube and is bent in its central portion about a side end by an angle of about 180°. In bending the flat tube, the overall cross-sectional area and height of the flat tube is maintained in the bent central portion. Additionally, the top and bottoms side walls of the flat tube are maintained planar and parallel with one another. When provided in a heat exchanger with other bent flat tubes, fins are located between adjacent flat tubes and are provided in the curved central portion. The bent flat tubes also connect to a header located on one side of the heat exchanger.

摘要： A heat exchanger element has a row of multiple channel flat pipes (3) that are mutually spaced apart and have ends connected in a fluid-tight manner to a tubular connector container (6) and to a tubular distributor (1). The ends of the multiple channel flat pipes (3) are separated into multiple zones (3′, 3″) shaped in such a way that each zone (3′, 3″) is parallel at its end on the side of the connection to the main plane of the multiple channel flat pipes (3), and the zones (3′, 3″) overlap at least partially in the direction of the longitudinal axis of the collector container (6) and distributor (1).
