Definitions

  • the present invention relates to a heat engine for a closed cycle with hot gas according to the Stirling principle with at least one hot and one cold room in preferably one cylinder each, in or on each of which a piston moving according to the process or a diaphragm bellows with tap mechanical energy works and with a regenerator for the working medium.
  • heat engines based on the Stirling principle each consist of an externally cooled or heated cylinder with pistons that are coupled to one another.
  • the two cylinders are connected by a tube and filled with a working gas, the working medium.
  • this gas for example helium or air, expands in the hot cylinder due to the heat supplied and pushes its piston downward, so that mechanical work is done.
  • the piston pushes the hot gas into the cold cylinder, the gas in the connecting pipe giving off heat to the regenerator placed therein, a heat accumulator and the cold heat exchanger following in the flow direction of the working gas and thereby cooling.
  • the piston in the cold cylinder leads that in the hot cylinder, that in the working cylinder, with a crankshaft drive by about a quarter of a turn, making room for the gas. Then when it starts to compress again, it compresses the gas and back into the hot cylinder. The gas absorbs the heat previously given off to the regenerator. Overall, the work done in the displacement is greater than that required to push the working gas. The difference between the work performed and the work to be performed then results in the work gained as an efficient part of the available energy after the completion of a cycle. The work is now available in mechanical form.
  • the known systems are therefore limited in performance and efficiency. They have long distances for the working medium and large dead volumes as well as flow resistance, especially at connection points and curvatures of the channels.
  • the object of the present invention is therefore to improve a heat engine according to the Stirling principle with regard to the heat exchange during the supply and dissipation of heat.
  • the present invention now proposes the features of a heat engine of the type described at the outset, which are set out in the characterizing part of claim 1 from a) to d). Further advantageous features for solving the task are specified in the characteristics of the subclaims.
  • the performance of a heat engine according to the Stirling principle is significantly increased. This is done according to the invention through the use of the novel, particularly combined and particularly compact heat exchanger unit, which is arranged in a particularly advantageous manner directly between the working and slide cylinders of the heat engine.
  • the heat exchanger 1 is a so-called micro-heat exchanger with a large aspect ratio, which is to be understood as the arithmetic ratio of the channel length to the dimensions of the internal structures (wall thicknesses or channel widths).
  • Micro heat exchangers that can be produced have aspect ratios of more than 10,000, the smallest dimensions of the inner structures being in the 10 ⁇ m range for wall thicknesses, in the 100 ⁇ m range for channel widths and the channel lengths in the cm range to a maximum in the m range.
  • the aspect ratio of such micro heat exchangers can be predetermined in a wide range, as can the shape and arrangement of the channels.
  • the micro heat exchanger 1 acc. 2 now consists of stacked, grooved, plate-shaped foils 10, the orientation of the grooves 11 being alternately offset by an angle, preferably 90 °, and the grooves 11 of a foil 10 with the back of the wall 12 of the foil lying above or lying against it 10 form the channels of the heat exchanger 1.
  • the heat exchanger 1 is constructed in the manner of a storage heat exchanger and has three types of channels 13, 14 and 15, which are formed from the grooves 11 described:
  • the channels 13 of the first type extend lengthways through the heat exchanger 1 and bring the working medium 9 flowing back and forth in them with the hot medium 18 in the channels 14 of the second type and the cold medium 19 in the channels 15 of the third type as in a cross-flow heat exchanger in heat exchange.
  • These channels 14 and 15 are arranged one behind the other approximately at right angles to the channels 13. Between them, the respective films 10 have an un-grooved part 20, which serves as a regenerator 21 for the Stirling process.
  • the channels 13 of the first type, which carry the working medium 9, lead directly from the hot space 5 into the cold 6, so that the flow losses become minimal.
  • the heat exchanger 1 shows the exact installation of the heat exchanger 1 in a Stirling engine.
  • This can be a mechanical work or a refrigerator, the type of micro heat exchanger described is suitable for all types of fluids.
  • the heat exchanger is seated in a housing 2, which is flanged directly between the two cylinders 3 and 4.
  • the heat exchanger is inserted so that the channels 13 of the first type connect the hot and the cold room 5 and 6 directly, so that the working medium 9 through the piston movements 22 and 23 with little loss back and forth between the rooms 5 and 6
  • the openings 26 and 27 of the housing 2, in which the front and rear surfaces 24 and 25 of the heat exchanger 1 are located each correspond to the cylinders 3 and 4 or their spaces 5 and 6.
  • the regenerator 21 or the corresponding one Zone of the heat exchanger 1 lies approximately in the middle of the housing 2, a thickening 28 in this area separates the channels 14 and 15 or their inflow areas 29 and 30 from each other.
  • the inflow regions 29 and 30 lie behind the inlet connections 31 and 32 for the hot 18 and the cold medium 19 on the other side of the housing 2, and the outlet connections 33 and 34 lie correspondingly at the outlet of the channels 14 and 15 from the heat exchanger 1.
  • the housing 2 of the heat exchanger 1 thus forms the cylinder head cover of both cylinders 3, 4 and thus has openings 26, 27 for the working medium 9 which correspond to the cylinders.
  • the surfaces 24, 25 of the heat exchanger 1 with the openings of the channels 13 of the first type each form the end of the hot 5 and the cold room 6.
  • the inlet 31, 32 and the outlet openings 33, 34 for the warm 18 and the cold medium 19 lie laterally transversely to the first openings 26, 27 in the housing 2 and correspond to the channels 14, 15 of the second and third types of the heat exchanger 1.
  • the regenerator part 21 of the heat exchanger 1 lies between them and separates them from one another.
  • the basic function of the Stirling process in the machine according to the invention is as described at the beginning.
  • the working medium 9 circulates through the channels 13 of the first type between the hot and the cold room 5 and 6.
  • the energy supply to the process through the hot medium 18 takes place via the channels 14 of the second type on the channels 13, the medium 18 through the Stub 31 and 33 is supplied or discharged.
  • the residual heat to be dissipated is dissipated in the channels 15 of the third type from the channels 13 of the first type by means of the cold medium 19, this medium 19 being supplied or removed through the connecting pieces 32 and 34. is derived.
  • part of the heat between the cold and hot zones is temporarily stored in accordance with the Stirling process, so that it serves as a thermal separation.
  • FIG. 3 shows how the heat exchanger according to FIGS. 1 and 2 is installed in a Stirling engine which has 7.8 membrane bellows 35 and 36 instead of the pistons.
  • the membrane bellows can have single bellows such as 35 or double or multiple bellows such as 36.
  • the mechanical work on the membranes is tapped here via plunger 37.
  • the hot space is here through the space 38 between the front surfaces 24 of the heat exchanger 1 and the membrane of the membrane bellows 35, the cold 39 between the rear surfaces 25 and the membrane of the membrane bellows 36 educated.
  • the control of the membranes in relation to one another is not shown since it is state of the art.
  • FIGS. 4 and 5 show the designs of the heat exchanger in other cylinder arrangements of the heat engine, the positions of the same elements corresponding to those in FIG. 1.
  • the heat exchanger is curved in an arc, in the parallel cylinder arrangement according to FIG. 5 with inclined side surfaces 26 and 27.
  • the principle of operation and the construction of the heat exchanger are the same as those described for FIG. 1, the function also.
