Abstract (en)
[origin: WO2020109013A1] The invention relates to a heat exchanger, comprising at least one partition and surface elements, which project at least from one side of the partition and enlarge the surface of the partition and around which a fluid can flow. The surface elements having reinforcing beads and planar regions located between the reinforcing beads. The reinforcing beads extend from the partition and have a circular or oval cross-sectional form. The reinforcing beads extend from the partition over at least part of the height of the surface element. The surface elements have a plurality of convex recesses. Each of the convex recesses is arranged in one of the planar regions between two reinforcing beads and extends from an outer edge of the surface element. The vertex of the convex recess lies at a height greater than or equal to 30% and less than or equal to 70% of the total height of the surface element, the height being measured from the partition.
