Embodiment Construction

[0044]FIG. 1 shows a schematic, perspective and partially cut-away view of a heat exchanger 1. Heat exchanger 1 is used to cool a cooling liquid for the internal combustion engine of a motor vehicle, and an air flow 16, whose flow direction is marked by the arrow, flows through the heat exchanger for this purpose.

[0045]Tubes 3 designed as flat tubes 4, between which wavy fins 13 are provided, are stacked in heat exchanger 1. Wavy fins 13 are used, on the one hand, to mechanically connect flat tubes 4 to each other, and also to elevate the surface of heat exchanger 1 in order to thereby improve the cooling capacity. A recess 5 is provided at an end 10 of flat tubes 4 (FIG. 3). Flat tube 4 includes a top wall 20, a bottom wall 21 and two side walls 22. Top wall 20 and bottom wall 21 are positioned a short distance above one another and connected to each other by the two curved side walls 22. Recess 5 is thus present in both top wall 20 and bottom wall 21. In the area of recess 5 of fl...

Abstract

A heat exchanger, in particular a heat exchanger for a motor vehicle, which is constructed from modular heat exchanger components can include the following types of heat exchanger components: a plurality of tubes, in particular flat tubes, a plurality of plates and at least one connecting piece having an inlet opening for introducing a fluid and / or an outlet opening for discharging the fluid, the outer contour of the heat exchanger being at least partially formed by the outer contours of the heat exchanger components, the reliable arrangement of the same type of heat exchanger component in the designated location within the heat exchanger is reliably guaranteed. Thus, the heat exchanger components of the same type have different outer contours which form an outer contour of the heat exchanger so that heat exchanger components of the same type but having different functions may be distinguished from each other on the basis of their different outer contours.

Description

[0001]This nonprovisional application claims priority under 35 U.S.C. §119(a) to German Patent Application No. DE 10 2008 053 308.4, which was filed in Germany on Oct. 27, 2008, and which is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a heat exchanger and to a method for manufacturing a heat exchanger. The invention also relates to a motor vehicle air conditioning system and a motor vehicle.[0004]2. Description of the Background Art[0005]Heat exchangers are used to transfer heat from one fluid to another fluid. For example, heat is transferred from a cooling liquid to the ambient air by a heat exchanger. This is used, in particular, in motor vehicles, in which the heat exchanger is used to discharge the waste heat released by the internal combustion engine into the ambient air. The heat exchanger generally includes two manifolds between which a plurality of tubes are arranged. Furthermore, heat exchangers ...
