Preferably, it is formed so that it can be deformed. This means that the protrusion 5 2. This is done by forming staggered patterns on the right and left sides along the connecting line 6 on the image. The resulting waveform is defined in terms of its "wavelength" by the longitudinal spacing of the staggered protrusions;
The amplitude j is defined by the depth or diameter of the protrusion. The best contour in this regard can be found by simple tests, taking into account the material of the cooling tube and the dimensions of the cooling tube.
