Definitions

  • the device By supplying and discharging media (gases, liquids), the device may be supplied with thermal energy, which can be transformed to a different temperature level and then be discharged.
  • thermal energy For the supply and discharge of media, pump systems are required. These pump systems must operate with low-maintenance and good efficiency. In the following, a pump system is disclosed which is particularly well suited for this application.
  • FIG. 1 shows an assembly 1 , to which a medium having a temperature ⁇ 1 is supplied, and from which a medium with temperature ⁇ 2 is discharged.
  • a medium having a temperature ⁇ 1 is supplied, and from which a medium with temperature ⁇ 2 is discharged.
  • rotary energy is input into such an assembly.
  • the rotational frequency of the rotational motion induced in the assembly by external drives must be low (in particular between 0.5 Hz and 20 Hz, preferably in the range of 1 Hz to 10 Hz).
  • These external drives can be formed, for example, by a combination of distinctly faster running, generally cylindrical shaped, electric motor 2 and a reduction gear 3 .
  • a distinctly disc-shaped, slow-running motor 4 is significantly more compact, quieter, lower-maintenance and more energy efficient.
  • the motor 4 can be particularly advantageously designed as a multi-pole axial flux motor.
  • FIG. 2 such a motor is illustrated as an asymmetrical (one sided) axial flow motor. It is designed as a synchronous motor and consists of a stator 5 and a rotor 6 .
  • a torque, and thus rotational motion, is generated in the permanent magnets 7 fixed to the rotor 6 by applying a rotating field to the coils 8 .
  • the torque can be transferred via the shaft 9 .
  • FIG. 3 shows an analogous device in the form of a symmetrical structured double-sided axial flow device. Also suitable for the above purpose is the use of a permanent magnet synchronous device according to the external rotor principle (see FIG. 4 ). Characteristic of both engine variants is the cavity between the rotor and stator.
  • the gap between the rotor and stator is in this case a particularly good way to house one or more pumps for transporting the heat conducting medium.
  • FIG. 5 shows how to put a pump system in an annular groove on the stator 5 according to the traveling wave principle.
  • the cam 10 By the rotational movement of the rotor 6 , the cam 10 periodically passes over the membrane assembly 11 , whereby a liquid or gaseous medium can be conveyed via the connections 12 and 13 .
  • the cross-section of the tubular membrane arrangement 11 corresponds to the arrangement described in the European patent EP 1317626 B1.
  • the pump can be operated virtually without wear and is virtually maintenance-free, quiet and efficient. In accordance with the principle of the traveling wave pump, no seals on moving parts are needed. Since little friction occurs between the cam 10 and diaphragm assembly 11 , the components involved are hardly subject to wear.
  • this pump arrangement can work by displacement or as a flow pump (e.g., via adjustable cam height), a wide range of pressure levels, for example in the range from 10 mbar to 20 bar, can be realized. Further, a not shown means for providing a variable magnetic field is provided.
  • FIG. 6 shows a further development of the arrangement with two independent media circulations via another concentric membrane assembly 14 and another cam 15 . Via the connections 16 and 17 another media circuit can operate. Furthermore, FIG. 6 shows that the membrane assemblies 11 and 14 would also be possible in different cross-sections (widths, heights). Therewith, for example, the different radial rotational speeds of the cam can be compensated to achieve the same flow rates in both circuits. However other mixed modes with different flow rates or pressure levels can be realized.
  • FIG. 7 shows a further development of the previous arrangement for a symmetrical (two-sided) designed axial flow, which as stated above can be realized in different variants.
  • FIG. 8 shows radially a circumferentially segmented arrangement. Segmentation can be implemented in any number and shape.
  • FIG. 9 shows an arrangement with a plurality of cams per orbit (any number and shape imaginable).
  • FIG. 10 shows further locations for the membrane assemblies.
  • FIG. 11 shows analogous conceivable positions of membrane assemblies in a permanent magnet synchronous machine according to the external rotor principle.
  • the pump system is merely exemplary housed in the gap between the rotor and the stator. Basically, the pump system can be arranged between any relatively moving components of the pump assembly or the drive unit. Further, the motor can be positioned to the side of the assembly or be integrated within the assembly at any point. In this respect, there results an integrated implementation with small space.
