Abstract

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.
