Abstract

'Solar motors' have been developed to make use of solar power, designed as a heat engine on the STIRLING-reciprocating piston principle placed at the focal point of a concave mirror. Despite the 42 % efficiency of the Stirling engine, the installation attained a total efficiency of only some 17 %, mainly owing to the hat losses at the 'receiver' and the relatively low efficiency of the concentrator (Schlaich & Partners system). The present invention makes use of a heat engine invented by the applicant which can be constructed with a very long shape without heavy costs owing to its relatively simple method of operation, so that the receiver area, using a parabolic mirror (higher concentrator efficiency than a concave mirror), is larger compared with prior art solar motors, thus providing better total efficiency. Thus, with this invention, a larger receiver area is also available when high-temperature exhaust gases are used to heat the receiver of the heat engine.

SolarmotorSolar motor

Es ist bekannt, daß 1816 R.STIRLING eine Wärmekraft¬ maschine zum Patent angemeldet hat.It is known that R.STIRLING patented a heat engine in 1816.

Zur Nutzung der Solarenergie sind u.a. sogenannte Solar¬ motoren entwickelt worden, bei denen eine Wärmekraftmaschine nach dem STIRLING-Hubkolbenprinzip verwendet wurde, die im Brennpunkt eines Hohlspiegels angebracht ist.The use of solar energy includes So-called solar motors have been developed, in which a heat engine according to the STIRLING reciprocating principle was used, which is attached at the focal point of a concave mirror.

Trotz des 42%igen Wirkungsgrad des Stirlingmotors, erreichte die Anlage nur einen Gesamtwirkungsgrad von etwa 17%, hauptsächlich wegen der Wärmeverluste am "Receiver" und dem relativ geringen Konzentratorwirkungsgrad. (System: Schlaich § Partner) .Despite the 42% efficiency of the Stirling engine, the system only achieved an overall efficiency of about 17%, mainly due to the heat losses at the "receiver" and the relatively low concentrator efficiency. (System: Schlaich § partner).

Vorliegende Erfindung besteht aus einer selbsterfundenen Wärmekraftmaschine, die durch ihre relativ einfache Funktions¬ weise ohne hohen Kostenaufwand sehi langgestreckt gebaut werden kann, sodaß die Receiverfläche mit Hilfe eines Parabol- spiegeis (höherer Konzentratorwirkungsgrad als beim Hohlspiegel verhältnismäßig groß im Vergleich zu bisherigen Solarmotoren ist, und so ein besserer Gesamtwirkungsgrad erzielt werden kann. Bei der Verwendung von Hochtemperaturabwärme aus Abgasen bzw. Verbrennungsprozessen zur Erhitzung des Receivers der Wärme¬ kraftmaschine, steht bei dieser Erfindung ebenso eine größere Receiverfläche zur Verfügung.The present invention consists of a self-invented heat engine which, due to its relatively simple function, can be built elongated without high cost, so that the receiver surface is relatively large compared to previous solar motors with the aid of a parabolic mirror (higher concentrator efficiency than concave mirror), and When using high-temperature waste heat from exhaust gases or combustion processes to heat the receiver of the heat engine, a larger receiver area is also available in this invention.

Als weiterer Vorteil vorliegender Erfindung ist die verhält¬ nismäßige Einfachheit der Wärmekraftmaschine zu nennen, sodaß diese kostengünstiger produziert werden könnte.Another advantage of the present invention is the relative simplicity of the heat engine, so that it could be produced more cheaply.

Das zuletzt geschriebene bezieht sich insbesondere auch auf den von Jürgen SCHUKEY erfundenen "Alpha-Omega-Motor" (SITA GmbH Hamburg) Nur die verhältnismäßige Einfachheit des konstruktiven Auf- baus der Wärmekraftmaschine ermöglicht die Längsstreckung des Kolbengehäuses und damit deren optimalen Verwendung für einen Parabolspiegel oder anderen Erhitzungsmedien (z.B: Hochtemperaturabwärme) .The last written refers in particular to the "Alpha Omega Motor" invented by Jürgen SCHUKEY (SITA GmbH Hamburg). Only the relative simplicity of the construction of the heat engine enables the piston housing to be stretched longitudinally and thus optimally used for a parabolic mirror or other heating media (e.g. high-temperature waste heat).
