Tubing system for transportation of reaction water of fuel cell system of motor car, has insulation portion defining low thermal conductive region between heating device and wall, so that thermal decoupling of heating device is enabled

摘要

The system has a coupling element (2) for attachment of a tubing (1) to an aperture (4) formed in a wall (5) i.e. pane, of a housing. The coupling element has an insulation portion (7) insertable through the aperture to enable a connection with the wall, where the insulation portion is made of material such as plastic, exhibiting thermal conductivity less than 5 W/mK. The insulation portion partially encloses a heating device (6) to define a low thermal conductive region between the heating device and the wall, so that thermal decoupling of the heating device from the wall is enabled.
