Abstract
A heat exchanger for the independent heating of the driver and front-seat passenger side of a passenger space, having flow pipes located at the ends of the heat exchanger at the transition between the upper and lower water compartment. These flow pipes are connected to the central flow connection via a flow channel transverse to the central flow connection and corresponding juncture channel. The transverse channel is located above a collecting chamber which is located at the lower side of the upper water compartment. The flow pipes guide the flow from the upper water compartment to the lower water compartment. Return pipes are positioned to guide the flow from the lower water compartment into the collecting chamber in the upper water compartment. From the collecting chamber the flow travels out of the upper water compartment through return connections.
