Abstract

The aggregates for feeding a circuit of a heat or cold supplying system, which are necessary for conveying the medium as well as for control and monitoring, are arranged, grouped together to form an assembly on pipelines for forward run and return run which run parallel to one another and ready to be installed, in a housing (20) made of heat-insulating plastic which is divided into a lower shell (20a) and an upper shell (20b) by a joint (21) running approximately in the central plane formed by the pipelines. The lower shell (20a) and the upper shell (20b) have along the common outer edges (22, 23) a folded connection (24) with folds forming a positive connection. The upper shell is provided with openings which permit the passage of the parts of the aggregates essential for the function, while the lower shell is provided with means (34) for direct wall fixing. In this case, the strength and the thickness of the material of lower shell and upper shell are selected in such a manner that the housing can be used both as protective transport packaging for the assembly and, after mounting, as a heat-insulating enclosure. <IMAGE>

Description

Beschreibung:Description:

Die Erfindung betrifft eine Vorrichtung zur Versorgung eines Kreislaufs einer Wärme- oder Kälteversorgungsanlage gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for supplying a circuit of a heating or cooling supply system according to the preamble of patent claim 1.

Bei der Installation von Heizungsanlagen sind, insbesondere wenn die Heizungsanlage mehrere Kreisläufe umfaßt, wie z.B. eine Warmwasserheizungsanlage, eine Fußbodenheizungsanlage sowie eine Brauchwasserbereitungsanlage, gegebenenfalls sogar noch eine Solaranlage, für jeden Kreislauf die zur Förderung des Wärmeträgermediums sowie zur Regelung und Überwachung erforderlichen Aggregate vorzusehen.When installing heating systems, especially if the heating system comprises several circuits, e.g. a hot water heating system, an underfloor heating system and a hot water preparation system, possibly even a solar system, for each circuit to provide the units required for conveying the heat transfer medium and for regulating and monitoring.

Um die bislang übliche, sehr arbeitsintensive periphere Installation dieser Aggregate und der dazugehörigen Rohrleitungen im Anschluß an einen Heizkessel zu erleichtern, ist es bereits bekanntgeworden, die für jeweils einen Kreislauf erforderlichen Aggregate, wie Umwälzpumpe, Regler, Mischer, Sicherheits- und Absperrorgane sowie Anzeige- und Bedienungselemente in einer werkseitig vormontierten Installationseinheit in einem kompakten Gehäuse zusammenzufassen (DE-Z "sh-technik", 1986, H. 5, S. 218, 219).In order to facilitate the previously very labor-intensive peripheral installation of these units and the associated pipelines connected to a boiler, it has already become known that the units required for each circuit, such as a circulating pump, controller, mixer, safety and shut-off devices and display units and control elements in a factory-assembled installation unit in a compact housing (DE-Z "sh-technik", 1986, H. 5, p. 218, 219).

Es ist auch schon bekannt, eine in einem Schrankbehälter montierte modulare Steuer- und Pumpeneinheit mit einer Wärmedämmung zu versehen (DE-A 34 16 574). Diese Wärmedämmung besteht aus Platten, die innerhalb des Schrankbehälters an ein Traggestell anmontiert sind. Schließlich ist es auch nicht mehr neu, bei einer Verteilereinheit, bei der die Aggregate in zu einem Paneel zusammengefaßte quaderförmige Hohlsäulen integriert sind, diese mit einer ihrem Korpus angepaßten Wärmedämmlage aus einer U-förmigen Schale und einer Platte zu versehen (DE-A 32 07 372).It is also known to provide a modular control and pump unit mounted in a cabinet container with thermal insulation (DE-A 34 16 574). This insulation consists of plates that are mounted on a support frame within the cabinet container. Finally, it is also no longer new for a distributor unit in which the units are integrated into cuboid-shaped hollow columns combined into a panel, to provide them with a thermal insulation layer made of a U-shaped shell and a plate (DE-A 32 07 372).

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die bei möglichst geringem Platzbedarf und verringertem Montageaufwand eine möglichst gute Wärmedämmung auch im Bereich der einzelnen Aggregate ermöglicht.Against this background, the invention is based on the object of specifying a device of the type mentioned at the outset which, with the smallest possible space requirement and reduced installation effort, enables the best possible thermal insulation even in the area of the individual units.

Diese Aufgabe wird gemäß der Erfindung durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of patent claim 1.

Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result from the subclaims.

Der Vorteil der Erfindung wird vor allem in gegenüber dem Stand der Technik weiteren Einsparungen an Zeit und Material bei Versand, Verkauf und Montage von vormontierten Installationseinheiten der eingangs angegebenen Art gesehen. Die Ausbildung des Gehäuses aus einer Unterschale und einer Oberschale aus wärmedämmendem Kunststoff entsprechender Festigkeit mit hinterschnittenen Falzverbindungen an den Rändern gestattet ein mehrfaches formschlüssiges Schließen und öffnen des Gehäuses. Wie bei Verpackungen aus aufgeschäumtem Kunststoff an sich bekannt, sind im inneren Bereich der Schalen durch Vertiefungen Hohlräume gebildet, die der jeweiligen Baugruppe in Form und Größe entsprechen und in welche die Baugruppen weitgehend umfangsschlüssig eingelegt werden können. Dadurch werden die Baugruppen nicht nur von dem wärmedämmenden Material so umschlossen, daß sie gegen Wärmeverluste im Betrieb geschützt sind, sondern auch gegen Verschiebungen gesichert, so daß das geschlossene Gehäuse zugleich als Transportverpackung dienen kann. Die Falzverbindung ermöglicht so ein beliebiges öffnen und Schließen des Gehäuses zunächst bei der werkseitigen Vorbereitung für den Versand, sodann bei der Montage und schließlich bei der Wartung oder bei Reparaturen an der Heizungsanlage.The advantage of the invention is seen above all in further savings in time and material compared to the prior art in shipping, sales and installation of preassembled installation units of the type specified at the outset. The design of the housing from a lower shell and an upper shell made of heat-insulating plastic of appropriate strength with undercut fold connections at the edges allows the housing to be closed and opened several times. As is known per se with packaging made of foamed plastic, cavities are formed in the inner region of the shells by depressions, which correspond to the respective assembly in shape and size and in which the assemblies can be inserted largely circumferentially. As a result, the modules are not only enclosed by the heat-insulating material so that they are protected against heat loss during operation, but also secured against displacement, so that the closed housing can also serve as transport packaging. The fold connection thus enables any opening and closing of the housing, first during the factory preparation for shipping, then during assembly and finally during maintenance or repairs to the Heating system.

Da die Baugruppen einschließlich ihrer einzelnen Aggregate während des Transportes zwar von dem Gehäuse umschlossen sein müssen, aber nicht über das Gehäuse hinausragen dürfen, andererseits aber einzelne Aggregate, wie insbesondere Pumpen, beim Betrieb Wärme entwickeln und deshalb nicht vollständig von wärmedämmendem Material eingehüllt sein dürfen, können in den Außenflächen der Oberschale Vertiefungen vorgesehen sein, die diese Aggregate zumindest bereichsweise freigeben. Zweckmäßig sind diese Vertiefungen als parallel zu dem die Aggregate aufweisenden Rohrstrang verlaufender Kanal ausgebildet, so daß die wärmeerzeugenden Aggregate im Sinne einer Konvektion von aufsteigender Luft umströmt werden können.Since the assemblies, including their individual units, have to be enclosed by the housing during transport, but may not protrude beyond the housing, on the other hand, individual units, such as pumps in particular, develop heat during operation and therefore must not be completely enveloped by heat-insulating material. can be provided in the outer surfaces of the upper shell recesses that release these aggregates at least in some areas. These depressions are expediently designed as a channel running parallel to the pipe string comprising the aggregates, so that the heat-generating aggregates can be flowed around by rising air in the sense of convection.

Die Schalen können auch nochmals unterteilt, auch entlang einer rechtwinklig zu der durch die Rohrstränge verlaufenden Mittelebene verlaufenden Ebene geteilt sein, so daß sie seitlich auf die Baugruppe aufsteckbar sind.The shells can also be subdivided again, also divided along a plane perpendicular to the central plane running through the tubing strands, so that they can be attached laterally to the assembly.

Als Werkstoff für die Schalen kommt bevorzugt Polypropylen zur Anwendung; es ist aber auch möglich, andere Werkstoffe einzusetzen, wie z.B. Polyäthylen, expandierbares Polystyrol (EPS), auch modifiziert ("Dytherm") oder Polyurethan. Dabei sind Form und Abmessungen der hinterschnittenen Falze an den Rändern der Schalen in Abhängigkeit von der Festigkeit und der elastischen Eigenschaften des wärmedämmenden Materials so zu wählen, daß die Falzverbindungen durch leichten Druck von oben auf die Oberschale unter elastischer Verformung eingerastet werden können, daß die dem Material innewohnende elastische Rückstellkraft aber groß genug ist, um die Falzverbindung auch nach mehrmaligem öffnen und Schließen geschlossen zu halten.Polypropylene is preferably used as the material for the shells; however, it is also possible to use other materials, e.g. Polyethylene, expandable polystyrene (EPS), whether or not modified ("Dytherm") or polyurethane. The shape and dimensions of the undercut folds on the edges of the shells depending on the strength and the elastic properties of the heat-insulating material should be chosen so that the fold connections can be snapped into place by applying slight pressure from above onto the top shell with elastic deformation, so that the Resilient resilience is inherent in the material but is large enough to keep the fold connection closed even after repeated opening and closing.

In den Randbereichen der Schalen sind Durchbrechungen für den Durchtritt von Rohranschlüssen vorgesehen, die zweckmäßigerweise so ausgebildet sind, daß auch die Wärmedämmung der Rohrleitungen ohne Kältebrücken an das wärmedämmende Material der Schalen angeschlossen werden kann. Durchbrechungen sind auch in der Oberschale des Gehäuses vorgesehen, um die für die Funktion der Anlage wesentlichen Teile, wie z.B. Pumpen, Absperrhähne, Thermometer und Manometer nach außen sichtbar bzw. bedienbar durchtreten zu lassen. Dabei ist darauf zu achten, daß die Durchbrechungen den Bedienelementen entsprechen, so daß die Oberschale ohne Demontage einzelner Teile abgenommen bzw. aufgesetzt werden kann.Openings for are in the edge areas of the shells the passage of pipe connections is provided, which are expediently designed so that the thermal insulation of the pipes can be connected to the heat-insulating material of the shells without cold bridges. Openings are also provided in the upper shell of the housing in order to allow the parts that are essential for the functioning of the system, such as pumps, stopcocks, thermometers and pressure gauges, to be visibly passed through or operated. It is important to ensure that the openings correspond to the controls, so that the top shell can be removed or replaced without disassembling individual parts.

Diese Aufnahmen sind, soweit möglich, der Form der Rohrstränge 1 und 2 sowie der Aggregate nachgebildet, so daß die metallischen Teile möglichst dicht vom wärmedämmenden Material umschlossen werden.The assembly A is surrounded by a housing 20, which consists of two shells, a lower shell 20a and an upper shell 20b. The two shells 20a and 20b consist of heat-insulating material of appropriate strength and thickness, expediently a foamed plastic, in particular polypropylene. Both the lower shell 20a and the upper shell 20b have receptacles on the inner sides, the illustration of which has been omitted for the sake of clarity. As far as possible, these recordings are modeled on the shape of the pipe strings 1 and 2 and the aggregates, so that the metallic parts are enclosed as tightly as possible by the heat-insulating material.

Die Trennfuge 21 zwischen den beiden Schalen 20a und 20b verläuft etwa in der Mittelebene der Baugruppe, so daß die Schalen 20a und 20b mittels einer entlang ihrer Ränder 22, 23 vorgesehenen Falzverbindung 24 zusammengesteckt werden können (Fig. 3a). Wie Fig. 3b erkennen läßt, die die Falzverbindung 24 in einem Zustand kurz vor dem Schließen zeigt, sind am Rand 23 der Oberschale 20b eine hinterschnittene Falzleiste 24a und am Rand 22 der Unterschale 20a eine hinterschnittene Nut 24b angeordnet. Die Breite b der Falzleiste 24a an der engsten Stelle und deren Höhe h sind ebenso wie der Neigungswinkel Alpha der Hinterschneidung und der dadurch bedingte Abstand a der Falzränder so dimensioniert, daß in Abhängigkeit von der Elastizität des verwendeten Materials ein Schnappeffekt erzielbar ist.The parting line 21 between the two shells 20a and 20b runs approximately in the center plane of the assembly, so that the shells 20a and 20b can be plugged together by means of a fold connection 24 provided along their edges 22, 23 (FIG. 3a). As can be seen in FIG. 3b, which shows the fold connection 24 in a state shortly before closing, an undercut fold strip 24a is arranged on the edge 23 of the upper shell 20b and an undercut groove 24b is arranged on the edge 22 of the lower shell 20a. The width b of the fold bar 24a at the narrowest point and its height h are dimensioned in the same way as the angle of inclination alpha of the undercut and the resulting distance a of the fold edges so that a snap effect can be achieved depending on the elasticity of the material used.

Zur Erleichterung des Zusammensteckens sind an einer Schale, z.B. an der Oberschale 20b, im inneren Bereich Zentrierbolzen 25 vorgesehen, die in entsprechende Aufnahmen 26 in der Unterschale 20a passen (Fig. 4a). Zur Erleichterung der Zentrierung können die Zentrierbolzen (25) zumindest an den äußeren Enden konisch ausgebildet sein. Um auch im Bereich der Zentrierbolzen 25 eine gewisse Verriegelungswirkung zu erreichen, können eine schwalbenschwanzförmige Verzahnung zwischen Zentrierbolzen 25' und Ausnehmung 26' (Fig. 4b) oder eine wulstförmige Verdickung am Zentrierbolzen 25'' vorgesehen sein, die in eine entsprechende Ringnut in der Ausnehmung 26'' paßt (Fig. 4c).To facilitate the plugging together, centering bolts 25 are provided on a shell, for example on the upper shell 20b, in the inner region, which fit into corresponding receptacles 26 in the lower shell 20a (FIG. 4a). To facilitate centering, the centering bolts (25) can be conical at least at the outer ends. In order to achieve a certain locking effect in the area of the centering pin 25, a dovetail-shaped toothing between centering pin 25 'and recess 26' (FIG. 4b) or a bead-shaped one Thickening may be provided on the centering pin 25 ″, which fits into a corresponding annular groove in the recess 26 ″ (FIG. 4c).

Im Bereich des Randes 22 der Unterschale 20a und des Randes 23 der Oberschale 20b sind Aussparungen 27 vorgesehen, um die jeweils anzuschließenden Rohrleitungen bzw. Aggregate hindurchtreten zu lassen. Diese Aussparungen 27 sind, wo erforderlich, so ausgebildet und von einer Ausnehmung 27' (Fig. 2) umgeben, so daß die wärmedämmenden Verkleidungen der anzuschließenden Rohrleitungen dicht eingebunden werden und die Anschlußstellen verdeckt sind.In the area of the edge 22 of the lower shell 20a and the edge 23 of the upper shell 20b, cutouts 27 are provided in order to allow the pipes or units to be connected to pass through. These recesses 27 are formed, where necessary, and surrounded by a recess 27 '(Fig. 2), so that the heat-insulating cladding of the pipes to be connected are tightly integrated and the connection points are covered.

Die Oberschale 20b besitzt in ihrer Vorderseite 28 eine Anzahl von Durchbrechungen, um die für die Funktion der Baugruppe wesentlichen Teile der Aggregate und Bedienelemente hindurchtreten zu lassen. Im einzelnen sind dies eine Durchbrechung 29 für die Pumpe 4, zwei Durchbrechungen 30 für die Thermometer 9 sowie zwei längliche Durchbrechungen 31 für die Knebel 32 der Kugelventile 5 bzw. 8. Die Abmessungen der Oberschale 20b sind so gewählt, daß die Oberflächen der Thermometer 9 und der Knebel 32 etwa in der Oberflächenebene der Oberschale 20b liegen. Im Bereich der Knebel 32 sind Vertiefungen 33 vorgesehen, um die Knebel drehen zu können. Das Gehäuse der Pumpe 4 muß im fertig montierten Zustand etwas über die Oberfläche der Oberschale 20b hinausragen, um die beim Betrieb der Pumpe entstehende Wärme durch Konvektion abzuführen und einen Wärmestau zu verhindern.The upper shell 20b has a number of openings in its front side 28 in order to allow the parts of the units and operating elements that are essential for the function of the assembly to pass through. Specifically, these are an opening 29 for the pump 4, two openings 30 for the thermometer 9 and two elongated openings 31 for the toggle 32 of the ball valves 5 and 8, respectively. The dimensions of the upper shell 20b are chosen such that the surfaces of the thermometers 9 and the toggle 32 lie approximately in the surface plane of the upper shell 20b. In the area of the knobs 32, depressions 33 are provided in order to be able to rotate the knobs. The housing of the pump 4 must protrude slightly above the surface of the upper shell 20b in the fully assembled state in order to dissipate the heat generated during operation of the pump by convection and to prevent heat accumulation.

Die Unterschale 20a ist zur unmittelbaren Wandbefestigung eingerichtet. Zu diesem Zweck sind klemmende Rohrschellen 34 vorgesehen, die in Fig. 1 lediglich angedeutet und in den Fig. 5a und 5b in größerem Maßstab dargestellt sind. Die Rohrschellen 34 bestehen zweckmäßig aus Kunststoff und haben etwa U-förmigen Querschnitt mit einem massiven Sockelteil 35 und zwei aufragenden Schenkeln 36, die der Form des Rohres 37 angepaßt sind und dieses bis über seinen größten Durchmesser hinweg klemmend umschließen. Das Sockelteil 35 liegt über eine Stabilisierungsschiene 38 aus Metall mit U-förmigem Querschnitt gegen den Boden 39 der Unterschale 20a an, die sich mit ihrem nach unten offenen Profil in das Material des Bodenteils 39 eindrückt. Durch das Sockelteil 35 erstreckt sich eine Befestigungsschraube 40, die in an sich bekannter Weise über einen Dübel 41 gegen die Gebäudewand 42 verschraubt ist. Auf diese Weise kann nicht nur die Wandbefestigung der Unterschale mit der Baugruppe A schon werkseitig vorbereitet werden, wodurch sich die Montage vereinfacht, sondern es wird durch diese Art der Befestigung auch eine etwaige Geräuschübertragung zwischen der Rohrleitung und dem Gebäude verhindert.The lower shell 20a is set up for direct wall mounting. For this purpose, clamping pipe clamps 34 are provided, which are only indicated in FIG. 1 and are shown on a larger scale in FIGS. 5a and 5b. The pipe clamps 34 suitably consist of plastic and have an approximately U-shaped cross section with a solid base part 35 and two upstanding legs 36 which are adapted to the shape of the tube 37 and enclose this by clamping over its largest diameter. The base part 35 bears against a stabilizing rail 38 made of metal with a U-shaped cross section against the bottom 39 of the lower shell 20a, which is pressed into the material of the bottom part 39 with its profile which is open at the bottom. A fastening screw 40 extends through the base part 35 and is screwed to the building wall 42 in a manner known per se via a dowel 41. In this way, not only can the wall fastening of the lower shell with assembly A be prepared at the factory, which simplifies assembly, but this type of fastening also prevents any noise transmission between the pipeline and the building.

In Fig. 6 ist angedeutet, wie unterschiedliche Baugruppen mit den ihnen jeweils zugeordneten Gehäusen zur Realisierung unterschiedlicher Heizkreisläufe baukastenartig nebeneinander angeordnet werden können. Nur schematisch ist eine Baugruppe A für einen Heizkreis mit Dreiwegemischer vorgesehen, die derjenigen entspricht, die anhand der Fig. 1 und 2 erläutert wurde. Dieser ist eine Baugruppe B ohne Mischer für gleitende Heizkreisregelung über die Kesseltemperatur nachgeordnet, wie sie beispielsweise für eine Fußbodenheizung verwendet werden kann. Schließlich folgt eine sogenannte Speicherladegruppe C für den Anschluß eines temperaturgeregelten Speichers zur Bereitung von Brauchwasser. Diese drei nur beispielhaft zu sehenden Baugruppen A, B und C sind nacheinander an einem Mehrfach-Heizkreisverteiler 43 angeschlossen, der seinerseits einen Anschluß 44 zum Kesselvorlauf und einen Anschluß 45 als Kesselrücklauf besitzt. Vor- und Rückläufe zu den einzelnen Kreisläufen sind jeweils durch Pfeile angedeutet.In Fig. 6 it is indicated how different assemblies with their respective housings can be arranged side by side in a modular manner to implement different heating circuits. A module A for a heating circuit with a three-way mixer is only schematically provided, which corresponds to that which was explained with reference to FIGS. 1 and 2. Subordinate to this is a subassembly B without a mixer for sliding heating circuit control via the boiler temperature, as can be used, for example, for underfloor heating. Finally, there is a so-called storage charging group C for connecting a temperature-controlled storage for the preparation of domestic water. These three modules A, B and C, which can only be seen as examples, are connected in succession to a multiple heating circuit distributor 43, which in turn has a connection 44 to the boiler flow and a connection 45 as a boiler return. Forward and return flows to the individual circuits are indicated by arrows.

Der Heizkreisverteiler 43 ist nach dem Zweikammersystem ausgebildet. Er hat stirnseitig einerseits einen Anschluß 46 für eine Sicherheitsgruppe D und andererseits einen Anschluß 47 z.B. für ein an sich bekanntes Druckausdehnungsgefäß. Die Sicherheitsgruppe D besteht aus einem Sicherheitsventil 48, einem Schnellentlüfter 49 und einem Manometer 50 mit Absperrung. Auch diese Sicherheitsgruppe D ist von einer wärmedämmenden Umhüllung 51 umgeben, die an diejenige der ihr zugeordneten Baugruppe A anschließbar ist.The heating circuit distributor 43 is designed according to the two-chamber system. It has a connection 46 for a security group D and a connection 47 e.g. for a pressure expansion vessel known per se. Safety group D consists of a safety valve 48, a quick vent 49 and a manometer 50 with shut-off. This security group D is also surrounded by a heat-insulating sheath 51 which can be connected to that of the assembly A assigned to it.

Eine andere Ausführungsform eines Gehäuses gemäß der Erfindung ist in Fig. 7 dargestellt. Bei dieser Ausführung sind in der Oberschale 20b' des Gehäuses 20' neben den Durchbrechungen für den Durchtritt der Aggregate, wie z.B. des Pumpengehäuses 4 und der Thermometer 9 kanalartige, parallel zu den Rohrsträngen verlaufende Vertiefungen 52 vorgesehen. Durch diese Vertiefungen 52 wird erreicht, daß z.B. der äußere Teil des Gehäuses der Pumpe 4 dem Luftzutritt frei zugänglich ist, ohne daß dessen Stirnseite über die Oberfläche der Oberschale 20b' hinauszuragen braucht. Durch die kanalartige, in vertikaler Richtung verlaufende Ausbildung der Vertiefungen 52, zusätzlich auch durch Schrägstellung ihrer Wände, wird eine Abgabe der am Pumpengehäuse entstehenden Wärme durch Konvektion ermöglicht.Another embodiment of a housing according to the invention is shown in FIG. 7. In this embodiment, in the upper shell 20b 'of the housing 20' in addition to the openings for the passage of the units, such as of the pump housing 4 and the thermometer 9 are channel-like depressions 52 which run parallel to the pipe strings. Through these depressions 52 it is achieved that e.g. the outer part of the housing of the pump 4 is freely accessible to the air, without the end face thereof having to protrude beyond the surface of the upper shell 20b '. Due to the channel-like design of the recesses 52, which runs in the vertical direction, and additionally due to the inclination of their walls, the heat generated on the pump housing can be released by convection.

In den Fig. 8a bis d sind noch einige Schnitte durch das Gehäuse 20' gemäß Fig. 7 dargestellt, die die Ausbildung der kanalartigen Vertiefungen 52 besser erkennen lassen. Fig. 8a ist ein Schnitt im normalen Bereich, der die kastenartige Gestalt des Gehäuses 20' erkennen läßt. Fig. 8b ist ein Schnitt durch den normalen ungestörten Bereich der kanalartigen Vertiefung 52, der die schrägen Seitenwände 53 und die schalenartige Umhüllung 54 der Rohrstränge erkennen läßt. Die Falzausbildung der Ränder ist der besseren Übersichtlichkeit halber weggelassen.8a to d show a number of sections through the housing 20 'according to FIG. 7, which show the formation of the channel-like depressions 52 better. Fig. 8a is a section in the normal range, which shows the box-like shape of the housing 20 '. 8b is a section through the normal, undisturbed region of the channel-like recess 52, which shows the oblique side walls 53 and the shell-like sheathing 54 of the pipe strands. The fold formation of the edges is omitted for the sake of clarity.

Die Fig. 8c und 8d schließlich zeigen noch Schnitte durch den Bereich der Thermometer 9 bzw. die - um 90 Grad gedrehten - Ventilknebel 32, um anzudeuten, wie diese zur Oberfläche 28 der Oberschale 20b' liegen.FIGS. 8c and 8d finally show sections through the area of the thermometer 9 or the valve toggles 32 rotated by 90 degrees in order to indicate how they lie to the surface 28 of the upper shell 20b '.
