Definitions

  • the invention is directed to a flat-collector Stirling machine for converting thermal energy into mechanical energy or vice versa comprising a displacer housing with a plate-like displacer which can be moved back and forth therein, as well as a heater, a regenerator and a cooler.
  • a Stirling engine is known for example from DE 42 16 839 l.
  • Flat-collector Stirling machines of the generic type are relatively simple in comparison to other Stirling machines.
  • Flat-collector Stirling machines consist of a flat displacer housing, into which a flat plate-like displacer is moved to and fro, around the working gas - mostly air - from the expansion space, the hot part of the displacer housing (mostly the upper area) via heater, regenerator and cooler into the compression space, the cold sub-space of the displacer housing (mostly the lower area), where heat is extracted from the working gas in the regenerator and temporarily stored there, and back again into the expansion space, heating, regenerator and cooler Flow through in reverse order and the heat removed in the regenerator is fed back to the working gas.
  • the working gas While the working gas is predominantly in the compression space, it has to be compressed with the expenditure of energy and the resulting compression heat has to be dissipated in the cooler. If the working gas is predominantly in the expansion space, it expands releasing mechanical energy, which is partly stored temporarily in an energy storage device for the following compression phase, and on the other hand can be removed using an energy decoupling device minus friction losses and work for the displacement movement.
  • this intermediate energy store for the compression phase consists of a flywheel or a pendulum. If a flywheel is used, the displacer has to be moved back and forth by the flywheel in the desired 90 ° phase shift (to the working piston) via relatively complicated mechanisms. If the displacer is not mechanically coupled to the crankshaft, undesired deviations from the 90 ° phase shift occur at different speeds because a free-floating displacer has only one preferred frequency. The energy is also extracted via the rotating shaft with the flywheel. The increase in performance manifests itself in increased speed.
  • pendulum is used as an intermediate energy store, about 1 t of pendulum mass must be used on a machine that is only supposed to deliver about 150 W of power, which has to swing back and forth about 2 m. The energy is also decoupled via the oscillating pendulum mass. This vibrating, heavy mass is extremely dangerous because it can tear its massive carrying frame out of its anchoring and is thrown in a high arc through the air if the load coupling fails.
  • the invention is based on the object of further improving such generic stirling machines to such an extent that they manage with a minimum number of moving mechanical parts that require maintenance, so that such machines can be used in such areas with low investment costs, where no high maintenance can be carried out.
  • the improved machines have the advantage over those with a rotating shaft that the increase in performance is due to the increase in the Working strokes and not in an increase in frequency or speed expresses to enable simple load coupling with high efficiency.
  • the displacer is formed by a heater, regenerator and cooler in such a way that the heater is arranged in the upper part of the displacer housing in such a way that it can be exposed to incident heat radiation in such a way that a displacer actuator forms a Return spring force to a central position of the displacer in the displacer housing, for moving the displacer as a function of the pressure conditions in the displacer housing and for balancing the weight of the displacer, as well as for stabilizing its position parallel to the base plate of the displacer housing, that an oscillatory compressor is provided. Water column is used for compressing and expanding the air in the displacer housing, and that an energy decoupling device is designed to dissipate the mechanical energy generated.
  • the mass of the displacer and the restoring force of the displacer actuator on the one hand and the mass of the compressor water column and the gas spring properties of the air in the displacer housing on the other hand are dimensioned such that the mass thus formed Spring systems have the same resonance frequency and accordingly resonance occurs between the compressor water column and the displacer, so that the displacer moves with a phase offset of 90 ° relative to the compressor water column.
  • the Stirling engine according to the invention has the advantage that it can be constructed using very simple components, all complicated mechanical components being largely avoided. Accordingly, such a machine is suitable both as a cheap and low-maintenance device, for example to convert the heat of the sun into mechanical energy for driving pumps or the like in hot areas, and also because of the captivating simplicity of the structure as an eye-catcher for window dressing decorations or as interior furnishings mobile . In the latter case, a simple finger pressure on the displacement box is used to start the machine, only sufficient light irradiation and thus a temperature difference between the top and bottom of the regenerator being required.
  • the vibratable water column is used according to the invention as an energy buffer for the compression phase.
  • This vibrating mass cannot do any damage even if the load coupling fails and the energy is not taken off, because the water column, as will be explained in more detail below, always has enough space in swing-out containers to also to carry out large amplitudes or the machine stops due to the design when the load ceases to exist, by using a separate work bellows or piston as the energy decoupling device, which makes such large strokes without load coupling that compression and expansion are no longer possible.
  • the water column is a particularly simple, wear-free component because it is at the same time an oscillating mass and a low-friction piston.
  • the 90 ° coupling of the movements of the displacer and the compressor water column does not take place mechanically but through resonance. For this purpose, it is only ensured that the frequency of the natural vibration of the displacer is the same as that of the natural vibration of the water column. This happens because the quotient of the spring constant of the restoring spring force of the displacement actuator and the mass of the displacer is equal to the quotient of the spring constant of the gas spring of the displacement volume, including the spring constant of the restoring force from the part of the water column subject to gravity and the active mass of the water column.
  • the displacer moves voluntarily with a 90 ° phase shift to the water column.
  • This resonant 90 ° coupling is very strict and, with separate energy extraction by means of a separate bellows or piston, is stable in every operating state without the need for mechanical components.
  • the compressor water column and displacer act on one another via the air pressure arrangement in the displacement box. If a temperature gradient is present above the regenerator and the displacer is displaced, the alternating heating and cooling of the air in the displacer produces a pressure fluctuation, which also stimulates the compressor water column to vibrate. If the temperature difference across the regenerator is large enough and heat is supplied via the heater, the vibration system is damped and mechanical energy can be dissipated.
  • the purpose of the displacement actuator is to move the displacer back and forth in the displacement housing with low friction, with little wear and tear, or to keep it movable and capable of vibrating.
  • the displacer actuator only prevents the tilting movements of the displacer plate during its up and down movement and ensures that it lies in the middle of the displacement box when the machine is not working Pressure changes in the displacement box to be deflected up or down.
