Abstract

A heat exchanger, particularly for a heating or air conditioning system for motor vehicles, includes at least one inlet channel and at least one outlet channel and at least one collector, which has at least two metal sheets or plates abutting each other, and a flow device through which a first medium can flow, while a second medium can flow around the flow device. The first medium is distributed by an inlet channel to the collector and to the flow device and can be conducted to an outlet channel, and at least one further channel for distributing the coolant is provided, which is connected in a communicating manner via at least one opening to the inlet channel.
