Abstract

PCT No. PCT/DE88/00476 Sec. 371 Date Mar. 27, 1989 Sec. 102(e) Date Mar. 27, 1989 PCT Filed Aug. 2, 1988 PCT Pub. No. WO89/00962 PCT Pub. Date Feb. 9, 1989.The thermostatically controllable tank container has a support structure with the dimensions of a parallelepipedic, standardized container. In the support structure (1) is provided a circular cylindrical tank (3) with a non-supporting thermal insulation jacket (4). Between the tank skin and the thermal insulation jacket are provided longitudinally directed ducts (9) for carrying a heating or cooling medium. The external diameter of the tank is essentially adapted to the internal dimensions of the square cross-section of the support structure, so that there is an optimum utilization by the cylinder of the theoretically available space of the parallepiped. The thermal insulation jacket adapted to the tank contour is arranged within the parallelepiped shape defined by the support structure (1). In cross-section, together with the circular cylindrical tank skin, the thermal insulation jacket (4) forms four crescent-shaped ducts (9) for carrying the heating or cooling medium and which are bounded in the longitudinal direction by the placing of the thermal insulation jacket on the circular cylindrical tank skin in the corresponding vertical and horizontal planes (tangents in cross-section). Thus, the invention provides a thermostatically controllable tank container with standardized external dimensions, whose internal space is utilized in optimum manner by the circular cylindrical tank. The four corners made available by the difference between the circle and the square are used for forming the crescent-shaped ducts. As the thermal insulation jacket (4) is also substantially circular, less insulating material is used in its manufacture.

Description

Die Erfindung betrifft einen temperierbaren Tankcontainer mit einer Stützkonstruktion, die die Außenabmessungen eines quaderförmigen Containers festlegt und der Abstützung eines kreiszylinderförmigen Tanks dient, mit einem nicht tragenden Wärmedämmantel im Bereich der Außenseite des Tanks, wobei zwischen der Tankhaut und dem Wärmedämmantel Kanäle zur Führung eines Kühl- oder Heizmediums entlang der als Wärmeaustauschfläche dienenden Tankhaut vorgesehen sind, und wobei der der Kontur des kreiszylinderförmigen Tanks angepaßte Wärmedämmantel innerhalb der durch die Stützkonstruktion definierten Quaderform angeordnet ist.The invention relates to a temperature-controllable tank container with a support structure which defines the outer dimensions of a cuboid container and serves to support a circular cylindrical tank with a non-load-bearing thermal insulation jacket in the region of the outside of the tank, channels between the tank skin and the thermal insulation jacket for guiding a cooling or heating medium are provided along the tank skin serving as the heat exchange surface, and the thermal insulation jacket adapted to the contour of the circular cylindrical tank is arranged within the cuboid shape defined by the support structure.

Ein derartiger temperierbarer Tankcontainer ist aus der DE-PS 2917364 bekannt, dessen Tank in einem Stützrahmen derart gelagert ist, daß er von dem Temperiermedium vollständig umspült wird, wobei die ebenen Wandflächen des Stützrahmens mit Wärmedämm-Material ausgerüstet sind. Dieser bekannte Tankcontainer ist praktisch ein herkömmlich genormter, quaderförmiger Container mit senkrechten und waagerechten ebenen Wandflächen, in dem ein verhältnismäßig kleiner Tank gelagert ist, so daß viel Raum zwischen den ebenen Wandflächen und der kreiszylindrischen Tankhaut freibleibt. Aus diesem Grunde ist auch das Tankvolumen im Verhältnis zu dem Innenvolumen des quaderförmigen genormten Containers verhältnismäßig klein. Vorzugsweise können senkrechte Wände oder Stege vorgesehen sein, die den Raum zwischen der kreiszylindrischen Tankhaut und den senkrechten Wänden des Wärmedämmantels in Kanäle zur Führung des Kühl- oder Heizmediums unterteilen.Such a temperature-controllable tank container is known from DE-PS 2917364, the tank of which is mounted in a support frame in such a way that it is completely washed around by the temperature control medium, the flat wall surfaces of the support frame being equipped with thermal insulation material. This well-known tank container is practically a conventionally standardized, cuboid container with vertical and horizontal flat wall surfaces, in which a relatively small tank is stored, so that a lot of space remains between the flat wall surfaces and the circular cylindrical tank skin. For this reason, the tank volume is also relatively small in relation to the inner volume of the cuboid standardized container. Vertical walls or webs can preferably be provided, which subdivide the space between the circular cylindrical tank skin and the vertical walls of the thermal insulation jacket into channels for guiding the cooling or heating medium.

Aus der GB-PS 1,225,325 ist ein ähnlicher temperierbarer Tankcontainer bekannt, bei dem der Wärmedämmantel einen kreiszylinderförmigen Querschnitt aufweist, und im Abstand zu dem Tank angeordnet ist. Der Abstand wird bestimmt durch am Umfang verlaufende Verstärkungsringe, die gleichzeitig die Kanäle für das Kühl- und Heizmedium festlegen. Der Tank mit seinem Wärmedämmantel ist in einer Stützkonstruktion angeordnet, die praktisch ein räumliches Fachwerk bildet. Auch bei diesem bekannten Tankcontainer wird der Raum, der durch die Stützkonstruktion definiert wird, nur sehr unvollständig als Transportraum ausgenutzt.A similar temperature-controllable tank container is known from GB-PS 1,225,325, in which the thermal insulation jacket has a circular-cylindrical cross section and is arranged at a distance from the tank. The distance is determined by reinforcement rings running around the circumference, which simultaneously define the channels for the cooling and heating medium. The tank with its thermal insulation jacket is arranged in a support structure that practically forms a spatial framework. With this known tank container, too, the space defined by the support structure is only incompletely used as a transport space.

Weiterhin sind Tankcontainer, die nicht heizbar oder kühlbar sind, bekannt, die einen Tank mit kreiszylindrischem Querschnitt aufweisen. Der Tank ist in seinem Querschnitt so groß, daß er den quadratischen Querschnitt, der durch die Normung des Containers festgelegt ist, möglichst ganz ausnutzt. Auf die Außenwand des Tanks ist dann ein Wärmedämmantel ohne Zwischenraum aufgebracht. Im Bereich der senkrechten und waagerechten Ebenen, d.h. an den "kritischen Stellen", kann der Wärmedämmantel etwas geschwächt sein, um für ein möglichst großes Volumen des Tanks zu sorgen. Dieser Tankcontainer ist aber weder kühl- noch heizbar.Furthermore, tank containers that cannot be heated or cooled are known that have a tank with a circular cylindrical cross section. The cross-section of the tank is so large that it takes full advantage of the square cross-section that is defined by the standardization of the container. A thermal insulation jacket is then applied to the outer wall of the tank without a space. In the area of the vertical and horizontal levels, ie at the "critical points", the thermal insulation jacket can be somewhat weakened in order to ensure the largest possible volume of the tank. However, this tank container cannot be cooled or heated.

Der Erfindung liegt die Aufgabe zugrunde, einen temperierbaren Tankcontainer der eingangs genannten Art zu schaffen, bei dem die durch die Stützkonstruktion und die Normung festgelegten Außenabmessungen für den Inhalt des Tanks möglichst optimal genutzt werden und gleichzeitig für eine gute und wirtschaftliche Kühlung bzw. Heizung gesorgt wird.The invention has for its object to provide a temperature-controllable tank container of the type mentioned, in which the external dimensions defined by the support structure and the standardization for the contents of the tank are used as optimally as possible and at the same time good and economical cooling or heating is ensured .

Diese Aufgabe wird nach dem Kennzeichen des Hauptanspruches dadurch gelöst, daß der Außendurchmesser des kreiszylinderförmigen Tanks den Innenabmessungen des quadratischen Querschnitts der Stützkonstruktion entspricht, daß die Kanäle zur Führung des Kühl- oder Heizmeidums im Querschnitt dadurch sichelförmig ausgebildet sind, daß der Wärmedämmantel an der Tankhaut im Bereich der senkrechten und waagerechten Querschnittstangenten anliegt.This object is achieved according to the characterizing part of the main claim in that the outside diameter of the circular cylindrical tank corresponds to the inside dimensions of the square cross section of the support structure, that the channels for guiding the cooling or heating medium are designed in a crescent shape in cross section in that the thermal insulation jacket on the tank skin in Area of the vertical and horizontal cross-sectional tangents.

Dadurch, daß der Tank in seinem Querschnitt praktisch so groß ist, wie der durch die Stützkonstruktion festgelegte quadratische Querschnitt, wird der durch die Containerabmessungen, d.h. durch die entsprechende Normung, zur Verfügung gestellte Querschnitt optimal genutzt. Der Wärmedämmantel wird als getrennte Schale in der Nähe des Tanks angeordnet. Die Schale weist lediglich eine etwas andere Krümmung (andere Radien) auf, so daß die sichelförmigen Kanäle zur Führung des Heiz- oder Kühlmediums entstehen. Normalerweise werden vier derartige sichelförmige Kanäle im Querschnitt gebildet. Es wird also das Volumenverhältnis des durch die Containerabmessungen zur Verfügung gestellten Raumes zu dem des Tanks verkleinert, so daß mehr Flüssigkeit bei gleichem Containervolumen transportiert werden kann; gleichzeitig werden ohne zusätzliche Bauteile Kanäle für das Kühl- und Heizmedium geschaffen, die so von dem Kühl- oder Heizmedium im Zwangsumlauf durchströmt werden, daß für einen guten Wärmeübergang gesorgt wird. Da der Wärmedämmantel im Querschnitt ebenfalls im wesentlichen kreisförmig ist, wird zu seiner Herstellung wenig Isoliermaterial im Vergleich zu einem quadratischen oder anderen geometrischen Querschnitt benötigt.Because the cross section of the tank is practically as large as the square cross section defined by the support structure, the cross section made available by the container dimensions, ie by the corresponding standardization, is optimally used. The thermal insulation jacket is arranged as a separate shell near the tank. The shell only has a slightly different curvature (other radii), so that the crescent-shaped channels for guiding the heating or cooling medium are formed. Usually, four such crescent-shaped channels are formed in cross section. The volume ratio of the space made available by the container dimensions to that of the tank is thus reduced, so that more Liquid can be transported with the same container volume; at the same time, channels for the cooling and heating medium are created without additional components, through which the cooling or heating medium flows in a forced circulation in such a way that good heat transfer is ensured. Since the thermal insulation jacket is also essentially circular in cross-section, little insulating material is required to produce it compared to a square or other geometric cross-section.

An den "kritischen Stellen", d.h. im Bereich der senkrechten und waagerechten Ebenen, dort, wo die sichelförmigen Kanäle zur Führung des Heiz- und Kühlmediums voneinander getrennt sind, kann der Wärmedämmantel etwas geschwächt sein, um eine möglichst optimale Raumausnutzung, d.h. Ausnutzung des Querschnitts, in diesem Bereich zu ermöglichen. Der Kompromiß zwischen der optimalen Raumausnutzung und einer ausreichenden Wärmedämmung in diesen Bereichen bei hinreichender Temperierung ergibt sich durch die sichelförmige Ausbildung der Kanäle.At the "critical points", i.e. In the area of the vertical and horizontal levels, where the crescent-shaped channels for guiding the heating and cooling medium are separated from each other, the thermal insulation jacket can be somewhat weakened in order to make the best possible use of space, i.e. Exploiting the cross-section to allow in this area. The compromise between the optimal use of space and sufficient thermal insulation in these areas with sufficient temperature control results from the crescent-shaped design of the channels.

In vorteilhafter Weise können, wie in Anspruch 3 unter Schutz gestellt, Kondensatwasserleitungen vorgesehen sein, damit das in den obenliegenden Kanälen entstehende Kondensatwasser in die unteren Kanäle ablaufen und dort an der tiefsten Stelle abtransportiert werden kann.In an advantageous manner, condensate water pipes can be provided, so that the condensate water that arises in the channels above can run off into the lower channels and can be transported away at the lowest point.

Grundsätzlich ist es möglich, so, wie in den Ansprüchen 4 und 5 definiert, den Tank zwischen den Stirnseiten entweder auf Füße zu stellen, oder ihn zwischen den Stirnseiten mit Hilfe entsprechender Bauteile einzuspannen und auf Füße oder andere Auflager zu verzichten.Basically, it is possible, as defined in claims 4 and 5, to either place the tank between the end faces on feet, or to clamp it between the end faces with the aid of corresponding components and to dispense with feet or other supports.

Zwischen Verbindungsring und Stützring kann ein Ring aus schlecht wärmeleitendem Material angeordnet sein, um in diesem Bereich "Wärme- oder Kältebrücken" zu verhindern.A ring of poorly heat-conducting material can be arranged between the connecting ring and the support ring in order to prevent "heat or cold bridges" in this area.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand zweier Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to the drawing using two exemplary embodiments.

In Fig. 1 ist der Tankcontainer nach der Erfindung perspektivisch lediglich mit seinen wesentlichen Bauteilen dargestellt. Die Rahmenkonstruktion ist durch eine stirnseitige Platte 1a angedeutet. Zwischen zwei dieser Platten ist der Tank 3 eingespannt. Der Tank 3 wird von einem Wärmedämmantel 4 umgeben. Es ist deutlich erkennbar, daß durch die Anlage des Wärmedämmantels 4 im Bereich der senkrechten und waagerechten Ebenen an dem Tank 3 vier sichelförmige, in Längsrichtung verlaufende Kanäle 9 entstehen, die der Führung des Kühl- oder Heizmediums dienen. Der Wärmedämmantel 4 ist an den Anlageflächen etwas schwächer ausgebildet, um den durch die quadratische Querschnittsform des genormten Containers festgelegte Abmessung möglichst optimal zu nutzen.In Fig. 1, the tank container according to the invention is shown in perspective only with its essential components. The frame construction is indicated by an end plate 1a. The tank 3 is clamped between two of these plates. The tank 3 is surrounded by a thermal insulation jacket 4. It can be clearly seen that by the installation of the thermal insulation jacket 4 in the area of vertical and horizontal planes on the tank 3, four crescent-shaped, longitudinal channels 9 are formed, which serve to guide the cooling or heating medium. The thermal insulation jacket 4 is designed to be somewhat weaker on the contact surfaces in order to use the dimension defined by the square cross-sectional shape of the standardized container as optimally as possible.

In den Fig. 2 und 3 ist eine Ausführungsform eines temperierbaren Tankcontainers mit einer Stützkonstruktion 1 dargestellt. Diese Stützkonstruktion bildet einen Stützrahmen mit rahmenförmigen Stirnseiten, die eine quadratische Fläche definieren. In dem Stützrahmen ist ein Tank 3 mit kreisförmigem Querschnitt angeordnet, wie es sich beim Betrachten der Fig. 2 und 3 ergibt. Die Tankhaut des Tanks 3 füllt den quadratischen Querschnitt, der durch die Rahmenkonstruktion 1 festgelegt ist, so vollständig aus, wie es unter praktischen Gesichtspunkten möglich ist. Die Abmessungen der Stützkonstruktion entsprechen der Containernormung. Bei dieser Ausführungsform tragen Füsse 2 den Tank 3. Diese Füsse 2 sind mit der Stützkonstruktion 1 verbunden.2 and 3, an embodiment of a temperature-controllable tank container with a support structure 1 is shown. This support structure forms a support frame with frame-shaped end faces that define a square area. A tank 3 with a circular cross section is arranged in the support frame, as can be seen when looking at FIGS. 2 and 3. The tank skin of the tank 3 fills the square cross section, which is defined by the frame construction 1, as completely as is possible from a practical point of view. The dimensions of the support structure correspond to the container standardization. In this embodiment, feet 2 carry the tank 3. These feet 2 are connected to the support structure 1.

Um den Tank 3 herum ist ein Wärmedämmantel 4 angeordnet, der im wesentlichen kreisförmig ist, aber lediglich in den Bereichen, in denen ausreichend Platz zur Verfügung steht, eine etwas stärkere Krümmung (kleinerer Radius) aufweist, so daß hier vier in Längsrichtung verlaufende und im Querschnitt sichelförmige Kanäle 9 entstehen. Dieses ist deutlich den Fig. 1 und 2 zu entnehmen. Diese Kanäle 9 dienen dem Zwangsumlauf des Kühl- oder Heizmediums, das an Anschlüssen an einer Stirnseite zu- und abgeführt wird. An den ebenfalls isolierten Stirnseiten sind entsprechende Hohlräume vorhanden, durch die das Kühl- oder Heizmedium entsprechend geleitet wird. An dem Eintrittsanschluß tritt das Kühl- oder Heizmedium in einen Hohlraum ein, der mit den beiden unteren Kanälen verbunden ist. Durch diese unteren Kanäle strömt das Heiz- oder Kühlmedium zu der anderen Stirnseite. In diesem Bereich ist ein durchgehender Hohlraum vorhanden, der dafür sorgt, daß das Kühl- oder Heizmedium in die beiden oberen Kanäle 9 eintritt und zurück zu der Ausgangsstirnseite strömt. Dort tritt es in einen oberen Hohlraum ein, der von dem unteren Hohlraum getrennt ist. In diesen oberen Hohlraum führt ein Anschluß, der den Austritt des Kühl- oder Heizmediums aus dem Tankcontainer ermöglicht.Around the tank 3, a thermal insulation jacket 4 is arranged, which is essentially circular, but only has a somewhat greater curvature (smaller radius) in the areas in which there is sufficient space, so that here four in the longitudinal direction and in Cross-section crescent-shaped channels 9 arise. This can be clearly seen in FIGS. 1 and 2. These channels 9 serve the forced circulation of the cooling or heating medium, which is supplied and discharged at connections on one end face. Corresponding cavities are present on the likewise insulated end faces, through which the cooling or heating medium is led accordingly. This occurs at the inlet connection Cooling or heating medium into a cavity that is connected to the two lower channels. The heating or cooling medium flows through these lower channels to the other end. In this area there is a continuous cavity which ensures that the cooling or heating medium enters the two upper channels 9 and flows back to the exit end face. There it enters an upper cavity that is separated from the lower cavity. A connection leads into this upper cavity, which allows the cooling or heating medium to exit the tank container.

Beim Betrachten der Fig. 1 wird deutlich, daß der Wärmedämmantel 4 in den senkrechten und waagerechten Ebenen, d.h. an den "kritischen Stellen", zur optimalen Ausnutzung des quadratischen Querschnitts des Stützrahmens 1 etwas geschwächt ist. Die Wandstärke des Wärmedämmantels ist hier geringer. Durch diese Schwächung kann der Tank etwas größer ausgeführt werden. Um den technisch vernünftigen Kompromiss zwischen einer optimalen Raumausnutzung und einer ausreichenden Wärmedämmung zu ermöglichen, nutzt man die sichelförmigen Kanäle aus, für die ausreichend Raum in den Eckbereichen des quadratischen Querschnitts zur Verfügung steht.Looking at Fig. 1 it is clear that the thermal insulation jacket 4 in the vertical and horizontal planes, i.e. at the "critical points" for optimal use of the square cross-section of the support frame 1 is somewhat weakened. The wall thickness of the thermal insulation jacket is smaller here. This weakening allows the tank to be made somewhat larger. To enable the technically reasonable compromise between optimal use of space and adequate thermal insulation, the crescent-shaped channels are used, for which there is sufficient space in the corner areas of the square cross-section.

Zwischen den übereinanderliegenden sichelförmigen Kanälen 9 für den Zwangsumlauf des Heiz- und Kühlmediums sind Kondensatwasserleitungen 8 (Fig. 2) vorgesehen, die bei der Herstellung des Wärmedämmantels durch Einlegen von Schläuchen oder dergl. gebildet werden. Das Kondensatwasser kann aus den obenliegenden Kanälen 9 in die darunterliegenden Kanäle 9 laufen, um gesammelt und abgeleitet zu werden.Between the superimposed sickle-shaped channels 9 for the forced circulation of the heating and cooling medium, condensate water pipes 8 (FIG. 2) are provided, which are formed during the production of the thermal insulation jacket by inserting hoses or the like. The condensate water can run from the overhead channels 9 into the underlying channels 9 to be collected and drained.

Durch die Erfindung wird ein temperierbarer Tankcontainer geschaffen, der den durch die Stützkonstruktion bzw. durch die Normung vorgegebenen Innenraum unter Beibehaltung des kreisförmigen Querschnitts des Tanks optimal ausnutzt. Die Fläche, die der Wärmedämmantel beansprucht, ist verhältnismäßig klein. Die Kanäle für das Heiz- und Kühlmedium werden dort geschaffen, wo unter Berücksichtigung des kreisförmigen Querschnitts des Tanks ausreichend Raum zur Verfügung steht, ohne daß die Raumausnutzung für den Tank hierdurch beeinträchtigt wird.The invention provides a temperature-controllable tank container that maintains the interior space specified by the support structure or by the standardization circular cross section of the tank is used optimally. The area that the thermal insulation jacket occupies is relatively small. The channels for the heating and cooling medium are created where there is sufficient space, taking into account the circular cross section of the tank, without the space utilization for the tank being impaired thereby.

Die Ausführungsformen nach den Fig. 4 bis 8 unterscheiden sich dadurch von derjenigen nach den Fig. 2 und 3, daß Füsse nicht vorhanden sind.The embodiments according to FIGS. 4 to 8 differ from those according to FIGS. 2 and 3 in that feet are not present.

Der Tank 3 ist zwischen den Stirnseiten, die rahmen- oder plattenförmig sein können, eingespannt. Dieses geschieht auf jeder Stirnseite mit Hilfe eines Verbindungsringes 5, der an der Tankhaut durch Schweißen befestigt ist. An dem Flansch dieses Verbindungsringes 5 ist durch Schrauben 7 ein Flansch eines Stützringes 6 befestigt. Dieser Stützring 6 ist mit den Stirnseiten der Stützkonstruktion 1 verbunden. Der Aufbau wird beim Betrachten der Fig. 7 deutlich. In Fig. 7 ist noch ein Flansch 10 zur Aufnahme von Armaturen dargestellt.The tank 3 is clamped between the end faces, which can be frame or plate-shaped. This is done on each end face with the help of a connecting ring 5 which is attached to the tank skin by welding. A flange of a support ring 6 is fastened to the flange of this connecting ring 5 by screws 7. This support ring 6 is connected to the end faces of the support structure 1. The structure becomes clear when viewing FIG. 7. In Fig. 7, a flange 10 is shown for receiving fittings.

Wie beim Betrachten der Fig. 7 weiterhin deutlich wird, ist zwischen dem Verbindungsring 5 und dem Stützring 6 ein Ring 12 angeordnet, der aus schlecht wäremeleitendem Material besteht. Die einzige Verbindung des Tanks 3 mit der Stützkonstruktion 1 erfolgt über den Verbindungsring 5, den man übrigens auch als Verbindungsmantel bezeichnen kann.As is also clear when looking at FIG. 7, a ring 12 is arranged between the connecting ring 5 and the support ring 6, which consists of poorly heat-conducting material. The only connection of the tank 3 to the support structure 1 takes place via the connecting ring 5, which can also be referred to as a connecting jacket.

Da nun zwischen dem Verbindungsring 5 und dem Stützring 6 der Ring 12 angeordnet ist, wird diese einzige "Wärme- oder Kältebrücke" unterbrochen, so daß die Isolierung des Tanks hierdurch noch verbessert wird.Since the ring 12 is now arranged between the connecting ring 5 and the support ring 6, this single “heat or cold bridge” is interrupted, so that the insulation of the tank is thereby further improved.

In Fig. 8 ist eine Einzelheit einer geschnittenen Seitenansicht in einer unteren Ecke im vergrößerten Maßstab der Ausführungsform nach den Fig. 4 bis 7 dargestellt. Zuerst ist der Wärmedämmantel 4 im Bereich der Stirnseite erkennbar. In dieser Darstellung weist der Wärmedämmantel eine Öffnung auf, die durch einen Deckel 13 verschlossen ist. Diese Öffnung dient dem Eintritt des Kühl- oder Heizmediums in einen Hohlraum 14, der mit den beiden unteren Kanälen 9 verbunden ist. Oben in Fig. 8 ist ein entsprechender Hohlraum 15 erkennbar, der mit den beiden oberen Kanälen 9 verbunden ist und eine nicht gezeigte Öffnung zum Austritt des Kühl- oder Heizmediums aufweist. Es ist aus Fig. 8 auch erkennbar, daß die beiden Hohlräume 14 und 15 voneinander getrennt sind. Die andere Stirnseite weist diese in Fig. 8 erkennbare Trennung nicht auf, so daß nur ein Hohlraum vorhanden ist, durch den das Kühl- oder Heizmedium von den unteren Kanälen 9 in die oberen Kanäle 9 übertreten kann.8 shows a detail of a sectional side view in a lower corner on an enlarged scale of the embodiment according to FIGS. 4 to 7. First of all, the thermal insulation jacket 4 can be seen in the region of the end face. In this illustration, the thermal insulation jacket has an opening which is closed by a cover 13. This opening serves the entry of the cooling or heating medium into a cavity 14 which is connected to the two lower channels 9. A corresponding cavity 15 can be seen at the top in FIG. 8, which is connected to the two upper channels 9 and has an opening (not shown) for the exit of the cooling or heating medium. It can also be seen from FIG. 8 that the two cavities 14 and 15 are separated from one another. The other end face does not have this separation, which can be seen in FIG. 8, so that there is only a cavity through which the cooling or heating medium can pass from the lower channels 9 into the upper channels 9.

Der zylinderförmige Wärmedämmantel 4 wird in Form von "Halbschalen" auf den Tank aufgesetzt. Die beiden Halbschalen mit annähernd halbkreisförmigem Querschnitt werden seitlich aufgeschoben und dann miteinander verbunden. Da der Tankcontainer entsprechend lang ist, werden in seiner Längsrichtung mehrere Halbschalen aufgesetzt und durch am Umfang verlaufende Ringe miteinander verbunden. An den Stirnseiten wird der Wärmedämmantel 4 dann so ausgebildet, wie es grundsätzlich in Fig. 8 erkennbar ist, wobei an der einen Stirnseite die Ein- und Austrittsöffnungen für das Kühl- oder Heizmedium mit den getrennten Hohlräumen 14 und 15 und an der anderen Stirnseite der entsprechende Hohlraum zum Umlenken vorgesehen sind.The cylindrical thermal insulation jacket 4 is placed on the tank in the form of "half-shells". The two half-shells with an approximately semicircular cross-section are pushed on to the side and then connected to one another. Since the tank container is correspondingly long, several half shells are placed in its longitudinal direction and connected to one another by rings running on the circumference. The thermal insulation jacket 4 is then formed on the end faces in the manner shown in FIG. 8, the inlet and outlet openings for the cooling or heating medium with the separate cavities 14 and 15 on one end face and the one on the other end face corresponding cavity for deflection are provided.
