Abstract

In an infrared analyser, essentially consisting of a housing, source arrangement, cuvettes and receiver, the source arrangement is directly coupled, mechanically and thermally, to an outer plate of the housing and together with the plate forms a sub-assembly.

Description

Die Erfindung betrifft einen Infrarotanalysator, der im wesentlichen aus den Baugruppen Gehäuse, Strahleranordnung, Küvetten und Empfänger besteht. Solche Analysatoren dienen der Analyse einer oder mehrerer Gaskomponenten in einem Gasgemisch. Sie sind mit mindestens einem thermischen Strahler ausgestattet, mindestens einer Küvette und mindestens einem Empfänger. Aus Kostengründen ist man dazu übergegangen, Einzel­ teile der Analysatoren durch Kleben miteinander zu verbinden. Bei der Klebeverbindung hat man darauf zu achten, daß einzelne Kleber eine hohe Betriebstemperatur nicht zulassen. Die Ge­ fahr der Überschreitung einer bestimmten Temperatur ist gegeben, wenn die Umgebungstemperatur unzulässig hoch ist.The invention relates to an infrared analyzer essentially from the components housing, radiator arrangement, Cuvettes and recipients exist. Such analyzers are used the analysis of one or more gas components in one Gas mixture. You are using at least one thermal radiator equipped, at least one cuvette and at least one Receiver. For reasons of cost one has gone over to single connect parts of the analyzers by gluing. With the adhesive connection you have to make sure that individual Do not allow glue to have a high operating temperature. The Ge If a certain temperature is exceeded, if the ambient temperature is impermissibly high.

Durch die Erfindung ist der durch die Wärmewirkung des thermi­ schen Strahlers hervorgerufene Nachteil in Gasanalysatoren be­ seitigt. Die Erfindung besteht darin, daß die Strahleranordnung mechanisch und thermisch unmittelbar an eine Außenplatte des Gehäuses angekoppelt ist und mit der Platte eine Baueinheit bildet. Vorzugsweise ist die Strahleranordnung an die Front­ platte des Gehäuses angekoppelt. By the invention of the thermal effect of the thermi the disadvantage in gas analyzers sides. The invention is that the radiator arrangement mechanically and thermally directly to an outer plate of the Housing is coupled and an assembly with the plate forms. The radiator arrangement is preferably at the front plate of the housing coupled.  

Durch Ausbildung des Gasanalysators nach der Erfindung ist gewährleistet, daß die durch die Strahleranordnung entwickelte Wärme durch die Frontplatte des Gehäuses nach außen abgegeben wird. Besteht die Befürchtung, daß Wärmeabgabe durch die ebene äußere Oberfläche der Frontplatte nicht ausreicht, was u. U. dann der Fall ist, wenn mehr als ein Infrarotstrahler mit der Frontplatte integriert ist, so wird die abstrahlende Oberfläche der Frontplatte vergrößert, insbesondere durch vertikal verlaufende Kühlrippen.By designing the gas analyzer according to the invention ensures that the developed by the emitter arrangement Heat is released to the outside through the front panel of the housing becomes. There is a fear that heat emission through the plane outer surface of the front panel is not sufficient, which u. U. then the case is when using more than one infrared heater the front panel is integrated, so the radiating Surface of the front panel enlarged, in particular by vertical cooling fins.

Ein zusätzlicher Wärmeschutz für den Empfänger läßt sich dadurch erreichen, daß der Empfänger über ein thermisch schlecht leitendes Verbindungsglied, z. B. über Analysator­ einheiten, wie Küvetten, an die Strahleranordnung angekoppelt wird.Additional heat protection for the receiver can be thereby achieve that the receiver has a thermal poorly conductive connector, e.g. B. via analyzer units, such as cuvettes, are coupled to the radiator arrangement becomes.

Die Erfindung wird an der Zeichnung eines Ausführungsbei­ spieles gemäß der Erfindung näher erläutert:The invention is illustrated in the drawing of an embodiment game according to the invention explained in more detail:

Wie die Zeichnung erkennen läßt sind zwei Gasaanlysatorein­ heiten 1 und 2 nebeneinander angeordnet. Der Strahler 3 sendet infrarotes Licht durch das Fenster 4 in das Küvettenpaar 5, durch das Filter 6 in den Empfänger 7. Der Strahler 8 sendet infrarotes Licht durch das Fenster 9 in das Küvettenpaar 10, das Filter 11 in den Empfänger 12.As the drawing shows two Gasaanlysatorein units 1 and 2 are arranged side by side. The radiator 3 sends infrared light through the window 4 into the pair of cuvettes 5 , through the filter 6 into the receiver 7 . The radiator 8 sends infrared light through the window 9 into the pair of cuvettes 10 , the filter 11 into the receiver 12 .

Die Strahlen der Strahler 3 und 8 werden durch die rotierende Blende 13 moduliert.The beams of the emitters 3 and 8 are modulated by the rotating diaphragm 13 .

Erfindungsgemäß sind die Strahler 3 und 8 in die Frontplatte 14 des Analysatorgehäuses eingebaut und bilden mit der Frontplatte eine bauliche Einheit. Bei Öffnen des Gehäuses werden die Analysatoreinheiten 1 und 2 zusammen mit der Frontplatte 14 nach außen geklappt. According to the invention, the emitters 3 and 8 are installed in the front plate 14 of the analyzer housing and form a structural unit with the front plate. When the housing is opened, the analyzer units 1 and 2 are folded out together with the front plate 14 .

Die Strahler sind mit Hilfe des thermisch gut leitenden Verbindungsgliedes 15 an die Fronttür 14 angeschlossen. Die Wärme der Strahler 3 und 8 wird durch das Verbindungsglied 15 an die Fronttür weitergeleitet und von dort abgestrahlt, wie durch die Pfeile 16 angedeutet. Zur Erhöhung des Ab­ strahleffektes sind an der Fronttür die Kühlrippen 17 angebracht.The radiators are connected to the front door 14 with the aid of the thermally highly conductive connecting member 15 . The heat of the radiators 3 and 8 is passed through the connecting member 15 to the front door and radiated from there, as indicated by the arrows 16 . To increase the radiation effect from the cooling fins 17 are attached to the front door.
