Abstract
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 (115The 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.
