A heat exchanger () has fluid flow channels () with at least one heat exchanging surface () which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E) the surface profile follows a first transverse wave (), at a second edge (E)the surface profile follows a second transverse wave () and at an intermediate point I between the edges the surface profile follows a third transverse wave (). The third transverse wave () has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.
