In Streckgit ⁇ tern be quickly and easily perforated by shearing large areas in plates, the recesses are formed as perfo ⁇ ration in the plates. In contrast to plates with ribs and fins comprises a stack of rolled Streckgit ⁇ tern on a larger surface area over which heat from a ⁇ exchange with a cooling fluid, for example air, can take place. The weight and material consumed is smaller with increased Oberflä ⁇ che. The cost and the cost of production are also lower.

  • a disadvantage over the variant described above is that the diameter of the cooling channels may not be precisely defined or equal over the device along the plane of the plate. This can lead to non-uniform flow conditions, and thus also temperature distributions, due to differential heat exchange, and can lead to increased wear in the case of cooling with cooling fluids with particles if the particles have increased rates of constriction and lead to material removal.
