Heat exchanger for a vehicle air condition

The heat exchanger (100) has flat pipes (102) for passage of a cold transfer medium, allowing heat exchange with the surrounding air and a number of parallel storage pipes (114) passing through the flat pipes in the transverse direction, containing a storage medium, e.g. a water solution with a phase transition at a temperature of between 3 and 7 degrees C. An Independent claim for an automobile air-conditioning unit is also included.
