Abstract

The device is for conveying gas from engines, partic. propulsion engines, to atmos. It comprises an extruded aluminium casing without transverse partitions and end-closures of different material partitioned to form chambers as necessary. Thermal gradients are created through walls by having cooler media on one side than on the other. The hot gas inlet pipe, fixed in the inlet-end closure, embodies systems whereby part of the incoming gas flows over surfaces swept on the other side by substantially cooler gas entering the outlet pipe. The cooled part of the gas is re-mixed with the hot gas before the mixture enters the aluminium portion of the device.

Description

Beschreibunv Diese Zusatzanmeldung zu P 28 04 875.1 stellt eine weitere Verbesserung der thermischen Gasführung dar, welche es ermöglicht1 eine kontinuierliche Heißgasbeaufschlagung von liuminium-vndungen in gröBerem Umfang vorzunehmen, als dies bisher infolge der bekannten Warmfestigkeitsminderungen dieses Werkstoffes möglich war. Der Grundgedanke der Hauptanmeldung, einen in der Regel als Strangpreßteil gefertigten Aiuminium-Bohlprofilkörper meist doppelwandig er Ausführung mit zellenartiger Unterteilung in Gasführungskanäle in Schließkörper einzufassen, welche die zur Raumbildung erforderlichen Querwandungen aufweisen, hat sich insbesondere im Zusammenhang mit mehrfachen Gegenstromanordnungen bewährt, die auf Wandungen des Aluminium-Rohlprofils und auf direkten iiarmefluB zwischen dem Zulauf- und dem Auslaufschließkörper bezogen sind, Anlaß war für die sorliegende Verbesserung zunächst die meßtechnische Bestellung, daß in Zulauf-Schließkörpern, wie sie z.B. die Figur 2 der Eauptnnmeldung zeigt, Wärmeakkumulationen stattfinden, durch welche die Heißgaseinlauftemperatur in aluminium-begrenzte Leitungen höher liegen können als die TemSeraturen in der Zulaufleitung in einen solchen SchlieBkörper. Dies wird durch die in den Patentansprüchen dieser Zusatzanmeldung beschriebenen Maßnahmen dadurch beseitigt, daß der ZulaufschlieEkörper, wie das Schema gemäß beiliegender Figur 1 zeigt, nicht einfach außen auf das Aluminium-Hohlprofil mit seinem ersten Entspannungsraum aufgesetzt wird, sondern in das Wärmeflußsystem des Gesamtgerätes integriert wird. Mit dem Anspruch 1 der Hauptanmeldung war dies dadurch bereits ermöglicht, daß direkter Wärmefluß zum Auslauf-Schließkörper vorgesehen war. Die vorliegende Verfeinerung in der Ausführung dieses Erfindungsgedankens geschieht gemäß Anspruch 1 dadurch, daß eine Teilmenge des zulaufenden Reißgases mit jenseitiger Kontaktfläche zu auslaufendem Abgas heruntergekühlt und in die verbliebene Reißgasmenge eingemischt wird, als Killilgas also, bevor das Heißgas in aluminiumbegrenzte Wandteile einläuft. Damit ist die MDglichkeit einer Wärmespeicherung im Einlaufschließkörper vollkommen ersetzt durch Wärmeabfuhr in den Auslaufschließkörper, und zwar in Gegenstrtomanordnung. Hinzu kommt, daß die Heißgasleitung (20) mit ihrer Umfangswandung (20) sofort bel Geräteintritt durch eine Verteilerkammer (14) hindurchgeführt wird, deren Terperaturniveau z.B. bei Vollasteinstellungen bzw. gewählter Höchsttemperaturbeaufschlagung des Gerätganzen um etwa 1CC tiefer liegt, weil sie erst nach Teperaturverlusten nacn ersten Gegenstromanordnungen beschickt wird. Dazu kommt als dritte thermische Maßnahme die Ausbildung des ersten aluminium-begrenzten Heißgaseinlaufraumes (7 in Figur ,) nicht in der Weise, daß dies lediglich die Öffnungsgruppe des ersten Teilstrombündels ist (vgl.Figur 2 der Hauptanmeldung P 28 04 875 Übergangsraum 4), sondern ein Ringraum (7 in beiliegender Figur 1), der Kontaktfläche zu allen Teilstromgruppen des Aluminium-Hohlprofils aufweist, also auch den Gruppen II und III, in denen bereits gekültes Abgas fließt0 In Patentanspruch 5 ist dies dargestellt. Zugleich mit diesen Maßnahmen wurden die schalldämpfenden Elemente des Gesamtgerätes intensiver ausgeführte Die Schemazeichnung geht aus von einem Aluminium-Hohlprofll, dessen Doppeiwandungen 20 Gasführungskanäle aufweisen, von denen je 7 zu den beiden ersten Gruppen gehören (I + II) und 6 zur letzten Aluminium-Teilstromgruppe. Der Übergang von Gruppe zu Gruppe erfolgt durch Verteilerkammern (h und B), die Bestandteile der Schließkörper sind. Die Figur 2 ist ein Schnitt in der in Figur 1 bezeichneten Ebene C/C. Description This additional application to P 28 04 875.1 represents another Improvement of the thermal gas flow, which makes it possible1 a continuous To apply hot gas to liuminium connections to a greater extent than this so far as a result of the known reductions in heat resistance of this material was possible. The basic idea of the main application, one usually as an extrusion Manufactured aluminum profile body usually double-walled he execution with cell-like Subdivision into gas ducts to be enclosed in closing bodies, which are used to form space have required transverse walls, has in particular in connection with proven multiple countercurrent arrangements on the walls of the aluminum raw profile and related to direct heat flow between the inlet and outlet closing bodies are, the reason for the careful improvement was initially the metrological order, that in inlet closing bodies, as shown, for example, in Figure 2 of the main notification, Heat accumulations take place, through which the hot gas inlet temperature in aluminum-limited Lines can be higher than the temperatures in the supply line in one such a closing body. This is indicated in the claims of this additional application The measures described are eliminated by the fact that the inlet closing body, such as the Scheme according to the enclosed Figure 1 shows, not simply on the outside of the aluminum hollow profile is put on with its first relaxation room, but in the heat flow system of the entire device is integrated. This was with claim 1 of the main application thereby already made possible that direct heat flow to the outlet closing body is provided was. The present refinement occurs in the practice of this inventive concept according to claim 1 characterized in that a subset of the inflowing tear gas with other-sided Contact surface to leaking exhaust gas is cooled down and into the remaining amount of tear gas is mixed in, as killil gas, so before the hot gas in aluminum-limited wall parts comes in. This makes it possible to store heat in the inlet closing body completely replaced by heat dissipation in the outlet closing body, in countercurrent arrangement. In addition, the hot gas line (20) with its peripheral wall (20) immediately bel device entry is passed through a distribution chamber (14) whose Temperature level e.g. with full load settings or selected maximum temperature loading of the device as a whole is about 1CC lower, because it is only after temperature losses is charged after the first countercurrent arrangements. There is also a third thermal Measure the formation of the first aluminum-limited hot gas inlet space (7 in figure,) not in such a way that this is only the opening group of the first Part of the flow bundle (see Figure 2 of the main application P 28 04 875 transition room 4), but an annular space (7 in the enclosed Figure 1), the contact surface to all partial flow groups of the aluminum hollow profile, including groups II and III, in which already cooled exhaust gas flows0 In claim 5 this is shown. At the same time with these Measures, the sound-absorbing elements of the entire device were carried out more intensively The schematic drawing is based on a hollow aluminum profile with double walls Have 20 gas ducts, 7 of which each belong to the first two groups (I + II) and 6 to the last aluminum substream group. The transition from group to Group takes place through distribution chambers (h and B), the components of the closing body are. FIG. 2 is a section in the plane C / C designated in FIG.
