End plate for a brazed heat exchanger comprising a pattern of relief printed ridges and grooves, wherein the end plate is limited by two long sides and two short sides and wherein media to be heat exchanged are supposed to flow mainly parallel to the long sides, the pattern comprising two arrow patterns wherein each arrow pattern is arranged on an opposite side of, and mirrors symmetrically compared to an axis running parallel to, and between the short sides of the end plate and wherein each arrow pattern running parallel to and between the short sides of the end plate has a tip angle substantially differing from a corresponding angle of fish bone patterned heat exchanger plates to be brazed to the end plate.
