Wärmetauscher mit Rippenrohren, insbesondere für Sonnenkollektoren Heat exchangers with finned tubes, in particular for solar collectors

Bekannt sind Plattenkollektoren (Rollbond, Rohre mit aufgesetzten Lamellen, Platten ini-c angelöteten oder angeschweißten Rohren) und Hochleistungskollektoren als evakuierte Zylinder. ErfindungsgeiaäS wird ein Alurainium-Preßprofil vorgeschlagen, dessen Form so gewählt wurde, daß die Strahlenreflexion auf das Heiz- und Kühlmittel führende Rohr erfolgt. Sin \\reiterer Vorteil besteht darin, daß das Verhältnis der Absorptionsfläche zur projezierten Kollektoroberfläche etwa 2 : 1 ist, wodurch der Wärmeverlust wesentlich reduziert wird (bekanntlich ist die ausstrahlende Fläche direkt: pronortionai dem Wärmeverlust)Plate collectors (roll bond, tubes with attached lamellas, plates ini-c soldered or welded on) are known Pipes) and high-performance collectors as evacuated cylinders. The invention is based on an Alurainium pressed profile proposed, the shape of which was chosen so that the radiation reflection on the heating and cooling means leading pipe takes place. Another advantage is that that the ratio of the absorption area to the projected Collector surface is about 2: 1, whereby the heat loss is significantly reduced (known is the radiating Area direct: pronortionai the heat loss)

In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt. Ss zeigen:In the drawing, the subject matter of the invention is shown for example. Ss show:

Fig. 3 und 4 Schnitte durch Alternativlösungen.3 and 4 sections through alternative solutions.

Wie man aus der Zeichnung erkennen kann, besteht der Kollektor aus nebeneinander angeordneten, vorzugsweise stranggepreßten Rippenrohren 1, die die seitwärts tangential an das Rohr 1 anschließend sich bogenförmig nach oben er-As you can see from the drawing, the Collector made of juxtaposed, preferably extruded finned tubes 1, which are tangential to the side on the pipe 1 then arcs upwards

streckenden Rippen 2 und 3 aufweisen. Die Enden der Rippen 2 und 3 übergreifen sich mit Hilfe horizontaler oder U-förmig gebogener Enden 4, so daß eine regendichte Bedachung entsteht. 7\n den Enden sind die einzelnen Rippenrohre 1 durch U-förmige,- in ihre Enden eingeschobene Rohrbogen 5 verbunden. Um eine Verschweißung oder Verklebung zu vermeiden, besitzen die Enden der Rohrbogen 5 Nuten 6, in denen O-Ringdichtungen 7 angeordnet sind.have stretching ribs 2 and 3. The ends of the ribs 2 and 3 overlap with the help of horizontal or U-shaped bent ends 4, so that a rainproof roof is created. 7 \ n the ends of the individual finned tubes 1 are through U-shaped pipe bends 5 inserted into their ends. In order to avoid welding or sticking, the ends of the pipe bends have 5 grooves 6 in which O-ring seals 7 are arranged.

Die Oberfläche des Preßprofiles, insbesondere des Heizoder Kühlmittel führenden Rohres 1, ist durch Rillen oder ähnliches vergrößert.The surface of the press profile, in particular the heating or Coolant leading pipe 1 is enlarged by grooves or the like.

Diese Profile 1 v/erden waagrecht angeordnet und mit kurzen Rohrkrümmern 5 und O-Ringen 7 verbunden bzw. abgedichtet.These profiles 1 are arranged horizontally and connected or sealed with short pipe bends 5 and O-rings 7.

Durch die waagrechte Anordnung und erfindungsgemäße Ausbildung des Preßprofiles ist die Luftkonvektion im Kollektor wesentlich reduziert (bekannt ist, daß die Luftkonvektion neben der Wärmeabstrahlung den größen Anteil der Wärmeverluste bei Kollektoren darstellt )· Die waagrechte Anordnung hat weiterhin den Vorteil, daß bei geeigneter Ausrichtung des Kollektors gegen Süden die Sonneneinstrahlung über den ganzen Tag ohne Richtungsänderung des Kollektors aufgefangen wird.Due to the horizontal arrangement and training according to the invention the air convection in the collector is significantly reduced (it is known that the air convection In addition to the heat radiation, the major part of the heat losses represents in collectors) · The horizontal arrangement has the further advantage that with suitable alignment of the collector towards the south, the solar radiation is collected throughout the day without changing the direction of the collector will.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. So können anstelle kreisbogenförmiger Rippen auch parabolische treten und das Rohr 1 kann sich im Brennpunkt der Parabel durch einen Steg mit den Rippen verbunden befinden.The invention is not restricted to the exemplary embodiments shown. So instead of a circular arc Ribs also occur parabolic and the tube 1 can be at the focal point of the parabola through a web with the ribs connected.

Ss ist auch möglich, ein Doppelrohr anzuordnen, wobei das eine Rohr an den Kältemittelkreislauf einer Wärmepumpe angeschlossen ist.Ss is also possible to arrange a double pipe, whereby the a pipe is connected to the refrigerant circuit of a heat pump.
