Heating system for motor vehicles has heat exchanger embedded between metal floor and carpet floor preferably with large contacting surface area

摘要

The heating system uses a heat exchanger associated with the vehicle floor (10) preferably with a large contacting surface area. The heat exchanger can be embedded between the metal floor plate (11) and the carpet floor (13) inside the noise insulating layer (12). Where a catalytic converter is mounted in the exhaust train and connected to the exhaust by a connecting clip a by-pass valve feeding the heat exchanger medium can be integrated in the connecting clip.
