The present invention relates to a heat exchanger having a cooling core consisting of a plurality of parallel, heat exchanging tubes 5 and two manifolds 1 provided with slots 4, where the ends of heat exchanging tubes 5 are inserted in fluid connection with each manifold and each slot 4 is defined by a slot opening 7 and parallel-running slot walls formed from deformed wall portions of the manifold. In order to improve a rigidity of construction of the heat exchanger the outer sides of said slot 4 are deformed inwardly relative to the manifold wall, forming concavities 2 in the manifold outer surface, the inner sides of said slot 4 are deformed inwardly relative to the manifold wall, forming convexities 3 in the manifold inner surface, and the convexities 3 comprise grooves 6 forming the slot walls 10 in order to accommodate at least a portion of the longitudinal edges of the end of exchanging tube 5. A method of manufacturing such a heat exchanger manifold is also provided.
