Heat exchanger with cold accumulator

A heat exchanger comprising:

• a first plurality of pipes configured to allow flow of refrigerant therethrough;
• a second plurality of pipes configured to allow flow of refrigerant therethrough;
• a plurality of cold accumulating pipes, each cold accumulating pipe comprising a refrigerant duct configured to allow flow of refrigerant therethrough, and a cold accumulating medium cavity configured to hold a cold accumulating medium, wherein, for each cold accumulating pipe, an elongated length of the cold accumulating medium cavity runs alongside a length of the refrigerant duct in a parallel manner;
• at least one upper collecting vessel comprising a first upper collecting vessel region and a second upper collecting vessel region;
• and
• at least one lower collecting vessel comprising a first lower collecting vessel region and a second lower collecting vessel region,
• wherein the first plurality of pipes, the second plurality of pipes, and the cold accumulating pipes are arranged in parallel,
• wherein ends of the first plurality of pipes are connected in a fluid-transmitting manner to the first upper collecting vessel region and the first lower collecting vessel region,
• wherein ends of the second plurality of pipes and ends of the refrigerant ducts are connected in a fluid-transmitting manner to the second upper collecting vessel region and the second lower collecting vessel region, and
• wherein the first plurality of pipes, the second plurality of pipes, and the plurality of cold accumulating pipes have a common width, and the first plurality of pipes is directly adjacent to the second plurality of pipes, the second plurality of pipes is directly adjacent to both the plurality of cold accumulating pipes and the first plurality of pipes, the plurality of cold accumulating pipes is directly adjacent to the second plurality of pipes but is not directly adjacent to the first plurality of pipes.
