Heat exchanger, in particular an evaporator, for a motor vehicle's air conditioning system has flow paths each with a multi-duct tube for coolant and inlet/outlet pipes to supply/drain the coolant

摘要

A collecting area (CA) (3) links to flow paths. Cooling air flows through a heat exchanger crosswise so as to cool a coolant. An inlet pipe (1) is oriented in a longitudinal direction on the CA and linked to it. Near its link to the CA, the inlet pipe has an effective pipe length in a longitudinal direction, which is considerably smaller than the effective overall length of the CA.
