Heat exchanger for automobile auxiliary heating device has temperature sensor for detecting temperature of heat transfer medium fitted in indent in heat exchanger wall

摘要

The heat exchanger (10) has an annular space (13), enclosing a combustion chamber (17) of an auxiliary heating device and supplied with a liquid heat transfer medium. A temperature sensor (22) for detecting the temperature of the heat transfer medium is fitted into an indent (18) provided in the wall (19) of the outlet connection (14) for the heat transfer medium, or in the outer wall of the heat exchanger defining the annular space.
