The invention relates to a heat exchanger (1), particularly for a heating or air conditioning system for motor vehicles, comprising 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 said flow device. The first medium is distributed by an inlet channel (2) to the collector (12) and to the flow device (8) and can be conducted to an outlet channel (3), characterized in that at least one further channel (4) for distributing the coolant is provided, which is connected in a communicating manner via at least one opening (19) to the inlet channel.
