Abstract (en)

u Through embossing, the flow direction of gas-like medium (7) forms a spike-like profile. At the tips of the spikes (9, 10, 11), there is a flow break for generating a turbulent flow pattern (13). The spike embossing may be periodically arranged at specific intervals (P) and between two opposing spikes (9, 11) the embossing height (PH) is such that the ratio of the height to the interval is either equal to or greater than 0.2 and is less than or equal to 0.25.The embossing height may be greater than 2 millimetres, preferably between 2.2 and 2.4 millimetres. There may be through-pipes (17) for heating rods, heating pipes or heating pipe rods, with the opening having no bordered edges.
