Abstract (en)

[origin: EP1248063A1] Heat exchanger, especially an evaporator in an air-conditioning system of a motor vehicle, used for transferring heat between a first and a second heat medium comprises a number of flat tubes (4, 4'') forming a block through which the first heat medium flows. The flat tubes are arranged in parallel so that channels for the second heat medium (3) entering at one end (6) of the block are formed in between adjacent flat tubes. The flat tubes extend in the direction of the block depth (t) at least over a partial section at an angle ( alpha ) to the end surface of the block. Preferred Features: The angle is about 25-65, preferably 45 degrees . The flat tubes have an angled or rounded undulating cross-section. The flat tubes are made by extruding a light-weight sheet metal, especially aluminum or an aluminum alloy.
