Abstract
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.

A collector tube for a heat exchanger having at least one flat tube, comprising:
- a base and a cover;
- the cover arranged opposite the base;
- the base and the cover defining a longitudinal duct;
- the base including at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger;
- the opening having at least one wide edge and at least one narrow edge;
- the longitudinal duct having, in a cross section, a diameter that is smaller than the at least one wide edge of the opening;
- wherein the at least one passage includes a collar extending away from the longitudinal duct;
- wherein the base has an outer base surface;
- and
- wherein a protective layer is disposed on at least a portion of the outer base surface.
A heat exchanger, for a vehicle, comprising:
- a plurality of flat tubes disposed spaced apart from one another;
- the plurality of flat tubes fluidically connected to one another via at least one collector tube, the at least one collector tube including:
- a base and a cover;
- the cover arranged opposite the base;
- the base and the cover defining a longitudinal duct;
- the base including at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger;
- the opening having at least one wide edge and at least one narrow edge;
- the longitudinal duct having, in a cross section, a diameter that is smaller than the at least one wide edge of the opening;
- wherein the at least one passage includes a collar extending away from the longitudinal duct;
- wherein the longitudinal duct has a semi-circular cross section including an arch area and a base area;
- wherein the arch area is formed by the cover;
- wherein a cover collar having a cover collar width is connected to each side of the arch area;
- wherein the base area is formed by the base;
- wherein the base includes a base collar having a predetermined material thickness;

A collector tube for a heat exchanger having at least one flat tube, comprising:
- a base and a cover arranged opposite the base such that the base and the cover define a longitudinal duct;
- a separating element arranged between the base and the cover, the separating element having a contour corresponding to a cross sectional contour of the longitudinal duct such that the separating element divides the longitudinal duct into fluid-tight segments;
- the base including at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger, the opening having at least one wide edge and at least one narrow edge;
- a cross section of the longitudinal duct having a diameter that is smaller than a length of the at least one wide edge of the opening;
- and
- wherein the base includes a collar surrounding the opening and protruding from the base away from the longitudinal duct.
