The invention relates to a heat exchanger, preferably a condenser, in particular for a motor vehicle, exhibiting: height, width, length, and tubes through which a first medium flows. A second medium flows around the tubes. The heat exchanger contains at least three rows across its width of tubes along its length. Each of the tubes are combined in the at least three rows to form at least one flow path for the first medium. The first row has at least one flow path through which the first medium flows vertically. The first flow path preferably comprises at least one third of the length of the heat exchanger, such that the temperature profile of the heat exchanger is improved. This is obtained in that the occurrence of disparities in the temperature profile is significantly reduced or even prevented.

Heat exchanger with optimized temperature profile

A heat exchanger that can be flowed through in the x-direction based on the heat exchanger, By way of this, a homogenous temperature distribution can be achieved.

Heat exchanger

A heat exchanger including a tube/rib block made up of tubes and ribs, the tubes forming fluid channels for conducting a first fluid, in particular a refrigerant, and the ribs arranged between the tubes forming a second fluid channel for conducting a second fluid, such as, in particular, air, which flows around the tubes, a collector being arranged at at least one end of the tube/rib block, which communicates with the fluid channels of the tubes, the at least one collector being provided with a plate-type design and including at least one base plate and a cover plate, which are stacked and soldered in a sealed manner, a spacer for spacing the base plate at a distance from the cover plate and for distributing the first fluid in the collector being provided.
