Vehicle passenger space heating system - has individual ribbed heater plates connected to coiled heater tube coupled to engine water circulation system

摘要

The heat exchangers are each formed as a ribbed plate working as a unit with a heater coil tube. The heater tube is connected to a hot water circulation system. The plate is provided with a surface contact protection layer (6) on one side and a vertically ribbed surface on the opposite side. The plate can be either hollow to accept a hot water coil or solid to be inserted inside a hot air shaft. The hot air shaft could be fitted in a door with the heat exchanger motor (12) located at the door pivot axis.
