Heat exchanger, particularly for a heating or air conditioning unit in a motor vehicle

摘要

The invention relates to a heat exchanger, particularly for a heating or air conditioning unit of a motor vehicle, comprising several flat pipes which are arranged parallel to each other and are penetrated by a heat-transmitting medium. An electrically operated heating element ( 114 ) which is mounted once the heat exchanger has been soldered is assigned to at least one part of the flat pipes as an additional heating device. Said heating element ( 114 ) is fixed to the heat exchanger by means of a holding element ( 115 The inventive heat exchanger is characterized by the fact that each heating element ( 114 ) is mounted in front of the corresponding flat pipe and parallel thereto by means of the holding element ( 125 ) which also runs parallel to the flat pipe.
