Abstract
The invention relates to a heating device for heating the interior of a motor vehicle, comprising a plurality of heating modules arranged in at least one heating unit, each heating module comprising at least one heating resistor, at least one heat exchanger configured for delivering heat generated by the heating resistor to an airflow, and a rectangular frame surrounding the at least one heating resistor and the at least one heat exchanger, each frame having openings in opposed frame legs, wherein in the at least one heating unit the frame legs, comprising openings, of adjacent heating modules face one another and electrical connection elements reaching through the openings electrically connect the heating modules to one another.
Claims13
A heating device for heating the interior of a motor vehicle, comprising:
- a plurality of heating modules arranged in a heating unit, each heating module comprising a heating resistor, a heat exchanger configured for delivering heat generated by the heating resistor to an airflow, and a rectangular frame surrounding the heating resistor and the heat exchanger, the frame having openings in opposed frame legs;
- and
- electrical connection elements;
- wherein the openings in frame legs of adjacent heating modules face one another and the electrical connection elements extend through the openings and electrically connect the heating modules to one another.
A heating module for a heating device, comprising:
- a heating resistor;
- a heat exchanger for dissipating heat generated by the heating resistor to an airflow;
- a rectangular frame which surrounds the heating resistor and the heat exchanger, the rectangular frame having a first frame leg and a second frame leg arranged opposite the first frame leg;
- and
- at least two male plug contacts which protrude from first openings in the first frame leg and at least two female plug contacts arranged in second openings in the second frame leg, the female plug contacts configured to mate with respective male plug contacts of an adjacent heating module.
