Definitions

  • the present invention relates to a rotor of a pressure wave machine according to the preamble of claim 1.
  • a critical factor for the process of a pressure wave machine is that the dimensions of the cells cannot be increased arbitrarily without influencing the pressure wave machine process and that rotors with different diameters must be provided for machines with different outputs.
  • the invention seeks to remedy this.
  • the object of the invention is to provide the cells in a rotor of a pressure wave machine of the type mentioned at the outset in such a way that they can be enlarged as desired without influencing a process taking place in the pressure wave machine.
  • the main advantage of the invention can be seen in the fact that the mixing processes take place in the same plane when the cells open and due to the Coriolis forces.
  • the dimension of the cell therefore only has to be kept small in the circumferential direction, while there is no restriction for the dimension of the cells in the axial direction. This can reduce the frictional resistance and heat transfer compared to an approximately square cell.
  • machines with different outputs can be manufactured by changing the rotor length with the same diameter.
  • a further advantage of the invention can be seen in the fact that the Coriolis forces which arise due to the radial movement in a system, among others, can be completely or partially compensated for by a suitable curvature of the cells in the peripheral direction for individual phases of the process.
  • FIG. 1 shows a cell rotor 1 which consists of a hollow inner part and which carries rotor cells 2 in a plane perpendicular to the axis of rotation of the cell rotor 1.
  • the rotor body carries on one side a hub 3 which has a bore for cooling or flow reasons.
  • This hub 3 is connected to the axial physical limitation of the cells 2 via a number of connecting elements 4.
  • the inflow 5, respectively. 5a and the outflow 6 respectively. 6a of the media also happens here perpendicular to the axis of rotation of the cell rotor 1.
  • This configuration means that the mixing processes when the cell is opened and due to the Coriolis forces resulting from the arrangement of the rotor cells 2 can take place in the same plane, which is preferably very advantageous for an energy exchange process .
  • the dimension of the rotor cells therefore only has to be kept small in the circumferential direction, while there is no restriction for the dimension of the rotor cells in the axial direction.
  • This allows the frictional resistance and the heat transfer compared to an approximately square cells, according to the prior art, are reduced. Machines with different outputs can thus be detected simply by changing the length of the cell rotor 1 without changing the diameter.
  • This enables a more compact series to be developed, and the possible uses of this cell rotor 1 increase disproportionately, because in most cases increasing the diameter of the cell rotor 1 offers an insurmountable structural precaution.
  • the geometric configuration of the connecting elements 4 reference is made to the explanations under FIG. 2.
  • the curvature is to be kept concave from the above-mentioned voltage engineering aspects, preferably with respect to the direction of rotation w of the rotor 1.
  • the number and the material thickness of the accumulator 4 depend on the respective size of the rotor 1 and on the dynamic forces to which the rotor 1 is subjected.
