- the partition plate 10 is provided with holes 56 which serve the partition plate to be fastened to the core plate 16 by means of holes 57 provided on the ribs 44. It it is also possible to attach the partition plate 10 in a different way, for example, that you can place them between the ribs 44 and the Cover plate 12 is stuck.
- the separating plate 10 separates the condensate channel 46 from one Steam return 49.
- the latter is through the partition plate 10 and the cover plate 12th formed, which is stationary both with the blade region 21 and with the hub 11 can be connected.
- both the cover plate 12 and the Core plate 16 rotatable by an axis 6 which, for. B. by a provided with a spring Bore 96 runs in the core plate 16.
- a Working fluid preferably water
- the blade area 21 gets into it by centrifugal force in the evaporation zone 14, where it with the copper gauze 23 in Touch comes.
- the heat generated by the blade edge 20 heats the Blade area 21 and causes the water, assisted by the negative pressure, the is preferably close to vacuum pressure, evaporates or boils. If the water its physical state changes, the water vapor moves to the center of the nucleus, because there is less pressure there.
- thermosiphon core any type of thermosiphon core can be used, e.g. B. also only from one component existing thermosiphon core.
- the present invention provides one excellent heat dissipation away from the blade area.
- the smooth, toothless Blade edge 20 it is possible to increase both the cut quality and the Wear of the cutting surface, its complexity and the maintenance effort to reduce.
- toothless for the present invention Blade cutting edge 20 is used, the use of a toothed cutting edge possible.
- a thermosiphon at atmospheric or higher pressure can be used. There are also others besides water Working fluids possible.
