A collector tube for a heat exchanger having at least one flat tube, may include a base and a cover arranged opposite the base. The base and the cover may define a longitudinal duct. The base may include at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger. The opening may have at least one wide edge and at least one narrow edge. The longitudinal duct may have, in a cross section, a diameter that is smaller than the at least one wide edge of the opening. The at least one passage may include a collar extending away from the longitudinal duct.

Collector tube for a heat exchanger

The invention relates to an air-conditioning system, in particular for a motor vehicle, in which a fan takes in air which flows through an evaporator and/or a heater, wherein the fan has arranged downstream of it an air-bypass channel, which contains a bypass damper and guides air past the evaporator. In the case of an air-conditioning system in which the air-mass flow which flows through the air-bypass channel and/or evaporator can be adjusted in a particularly variable manner, an air-throttle element is arranged in and/or on the air-bypass channel and/or upstream or downstream of the evaporator.
