Claim:
A heat exchanger for a motor vehicle air conditioning system comprising: a first region comprising first and second rows, each of the first and second rows including a first plurality of mutually adjacent, refrigerant-carrying tubes; a second region, placed downstream of the first region in a direction of air flowing through the heat exchanger, and comprising a third row distinct from the first and second rows, the third row including a second plurality of mutually adjacent, refrigerant-carrying tubes and at least one cold store configured to be provided with a cold storage medium; wherein the cold store is not in the first region; and at least one overflow opening configured to connect the first region and the second region, wherein the first region and the second region are mutually parallel, wherein the first and second rows of tubes are arranged one behind the other in the direction of air flowing through the heat exchanger, and the second and third rows of tubes are arranged one behind the other in the direction of air flow through the heat exchanger, wherein the cold store is disposed such that at least a part of a refrigerant flow can flow through the cold store, wherein at least part of the refrigerant flow can flow through the first region, and wherein at least one first reservoir for a refrigerant and at least one second reservoir for the cold storage medium are formed substantially from three sheet-metal molded parts, comprising a base part, an intermediate part and a cover part.
