Abstract: The invention relates to a heat exchanger, in particular an evaporator (1), with a plurality of refrigerant-carrying pipes (6, 7) which are arranged next to one another and end in at least one collecting vessel (9), and with at least one cold accumulator (4), in which a cold accumulating medium is provided, wherein the evaporator (1) has two regions arranged parallel to each other, a first region (1?) and a second region (1?), and the cold accumulator (4) is arranged in the second region (1?). In this case, the refrigerant-carrying pipes (6, 7) of the first and second regions (1?,1?) are arranged in line with one another and have a width corresponding to one another (b1, b2, b3), and the first and second regions (1?, 1?) have common, continuous corrugated rib.

Abstract: The invention relates to a heat exchanger, in particular, an evaporator (1), in particular for a motor vehicle air-conditioner, with a number of closely arranged refrigerant tubes and at least one cold reservoir (4), in which a refrigerant medium is provided. The evaporator (1) comprises two parallel regions (1? and 1?) running across the total width, the first region (1?) corresponding to a conventional evaporator in design, the cold reservoir (4) being arranged in a separate second region (1?), through which at least a partial flow of refrigerant can flow which also flows through at least a part of the first region (1?) and the first and the second region are connected to each other by at least one overflow opening (13).
