Description

Wärmeübertrager  Heat exchanger
Die Erfindung betrifft einen Wärmeübertrager zur Erwärmung fließfähi- ger Medien, insbesondere hochviskoser Materialien, Beschichtungsmate- rialien oder dergleichen, umfassend einen Profilkörper mit zumindest einem Durchflusskanalabschnitt eines Durchflusskanals des Wärmeübertragers und eine im Profilkörper angeordnete Heizeinrichtung, wobei die Heizeinrichtung zumindest zwei elektrische Heizelemente aufweist. The invention relates to a heat exchanger for heating flowable media, in particular highly viscous materials, coating materials or the like, comprising a profile body with at least one flow passage section of a flow channel of the heat exchanger and a heating device arranged in the profile body, wherein the heating device has at least two electrical heating elements.
Wärmeübertrager dieser Art sind hinreichend bekannt und werden regelmäßig in Art eines Durchlauferhitzers zur Erwärmung von Beschich- tungsmaterialien auf dem Gebiet der Spritztechnik verwendet. Das Beschichtungsmaterial wird dabei mittels einer Pumpe durch den Durch- flusskanal des Wärmeübertragers gefördert, wobei eine Erwärmung des Beschichtungsmaterials durch die Berührung desselben mit Wärmeübertragerflächen innerhalb des Durchflusskanals erfolgt. Zur Erzeugung der Wärmeenergie werden regelmäßig elektrische Heizelemente verwendet, die in einem dem Durchflusskanal zumindest abschnittsweise ausbil- denden Körper des Wärmeübertragers angeordnet sind. Das oder dieHeat exchangers of this type are well known and are regularly used in the manner of a continuous flow heater for heating coating materials in the field of spray technology. The coating material is thereby conveyed by means of a pump through the flow channel of the heat exchanger, with heating of the coating material taking place by contact with heat exchanger surfaces within the flow channel. To generate the heat energy, electrical heating elements are used regularly, which are arranged in a body of the heat exchanger forming the flow channel at least in sections. That or the
Heizelemente müssen dann so in dem Körper angeordnet sein, dass eine gleichmäßige Erwärmung des Durchflusskanals erfolgt. Nachteilig ist hier insbesondere, dass die Wärmeübertragung von den Heizelementen auf das Beschichtungsmaterial nur indirekt erfolgt und zunächst der aus Metall ausgebildete Körper erwärmt werden muss. Weiter sind Ausführungsformen von Wärmeübertragern bekannt, bei denen ein Heizelement unmittelbar im Durchflusskanal angeordnet ist. Hier ist zwar eine schnelle und effektive Erwärmung des Beschichtungs- materials möglich, jedoch besteht bei der vergleichsweise kleinen Wärmeübertragerfläche des Heizelements die Gefahr einer Überhitzung des Beschichtungsmaterials. Auch kann dann das Beschichtungsmaterial leicht an einer Heizelementfläche anbacken bzw. sich ablagern, was wiederum zu einer Verstopfung des Durchflusskanals führen kann. Mit der Anordnung der Heizelemente im Körper ist demgegenüber ein vergleichsweise kleinerer Temperaturgradient zwischen einer Durchflusska- nalinnenfläche und dem Beschichtungsmaterial erzielbar, jedoch bedarf es in diesem Fall der Ausbildung eines vergleichsweise langen Durchflusskanals zur Ausbildung einer notwendigerweise größeren Wärmeübertragerfläche. Nachteilig ergibt sich hieraus eine komplizierte Kanalführung bzw. ein aufwendiger Aufbau des Körpers, insbesondere da der Wärmeübertrager häufig in Verbindung mit einem mobilen Spritzgerät verwendet wird und somit in seinen Abmessungen relativ kompakt sein muss. Heating elements must then be arranged in the body so that a uniform heating of the flow channel takes place. The disadvantage here, in particular, is that the heat transfer from the heating elements to the coating material takes place only indirectly, and first the body formed of metal has to be heated. Furthermore, embodiments of heat exchangers are known in which a heating element is arranged directly in the flow channel. Although a rapid and effective heating of the coating material is possible here, there is the risk of overheating of the coating material in the case of the comparatively small heat exchanger surface of the heating element. Also, then the coating material can easily caking or deposit on a Heizelementfläche, which in turn can lead to a blockage of the flow channel. By contrast, with the arrangement of the heating elements in the body, a comparatively smaller temperature gradient between a flow channel inner surface and the coating material can be achieved, but in this case the formation of a comparatively long flow channel requires formation of a necessarily larger heat transfer surface. The disadvantage of this results in a complicated ducting or a complex structure of the body, especially since the heat exchanger is often used in conjunction with a mobile sprayer and thus must be relatively compact in its dimensions.
Auch ist häufig eine Reinigung des Durchflusskanals notwendig, beispielsweise bei einem Wechsel der Beschichtungsmaterialien, bei einer Verstopfung oder nach Beendigung eines Beschichtungsvorgangs, wobei der Wärmeübertrager und insbesondere der Durchflusskanal dann regelmäßig umständlich demontierbar bzw. schlecht zu reinigen ist. Dies ist vornehmlich bei dem aus dem Stand der Technik bekannten Wärmeübertragern der Fall, da der Durchflusskanal im Körper Knickungen oder Bögen ausbildet, die nur schwer mit Reinigungswerkzeug zu erreichen sind oder die eine zeitaufwendige Demontage des Wärmeübertragers bedingen. Also, a cleaning of the flow channel is often necessary, for example, when changing the coating materials in a blockage or after completion of a coating process, the heat exchanger and in particular the flow channel is then regularly cumbersome disassembled or difficult to clean. This is primarily the case with the heat exchangers known from the prior art, since the flow channel in the body forms kinks or bends, which are difficult to achieve with a cleaning tool or which require a time-consuming disassembly of the heat exchanger.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Wärmeübertrager vorzuschlagen, der einen einfachen und kompakten, leicht zu reinigenden Aufbau aufweist und dennoch eine verbesserte Wärmeübertragung ermöglicht. The present invention is therefore based on the object to propose a heat exchanger, which has a simple and compact, easy-to-clean construction and yet allows improved heat transfer.
Diese Aufgabe wird durch einen Wärmeübertrager mit den Merkmalen des Anspruchs 1 gelöst. This object is achieved by a heat exchanger with the features of claim 1.
Der erfindungsgemäße Wärmeübertrager zur Erwärmung fließfähiger Medien, insbesondere hochviskoser Materialien, Beschichtungsmateria- lien oder dergleichen, umfasst einen Profilkörper mit zumindest einem Durchflusskanalabschnitt eines Durchflusskanals des Wärmeübertragers und eine im Profilkörper angeordnete Heizeinrichtung, wobei die Heizeinrichtung zumindest zwei elektrische Heizelemente aufweist, wobei ein erstes Heizelement in einer im Profilkörper ausgebildeten Heizelementaufnahme angeordnet ist, und ein zweites Heizelement in einem Hülsenelement der Heizeinrichtung angeordnet ist, wobei das Hülsenelement in dem im Profilkörper ausgebildeten Durchflusskanalabschnitt angeordnet ist, derart, dass die Heizelemente gegenüber dem Durchflusskanal abge- dichtet sind. The heat exchanger according to the invention for heating flowable media, in particular highly viscous materials, Beschichtungsmateria- or the like, comprising a profile body with at least one flow passage portion of a flow channel of the heat exchanger and arranged in the profile body heater, wherein the heater has at least two electrical heating elements, wherein a first heating element in a heating element receptacle formed in the profile body is arranged, and a second heating element is arranged in a sleeve element of the heating device, wherein the sleeve element is arranged in the flow passage section formed in the profile body, such that the heating elements are sealed off from the flow channel.
Insbesondere die Erwärmung des Profilköpers mit einem Heizelement und der Einsatz des ebenfalls beheizten Hülsenelements in dem Durchflusskanalabschnitt ermöglicht eine besonders wirkungsvolle Wärmeübertragung auf das fließfähige Medium, da die effektiv beheizten Wärmeübertragerflächen relativ groß sind. So gelangt das fließfähigeIn particular, the heating of the Profilköpers with a heating element and the use of the likewise heated sleeve member in the flow passage section allows a particularly effective heat transfer to the flowable medium, since the effectively heated heat exchanger surfaces are relatively large. So gets the flowable
Medium mit einer Durchflusskanalinnenfläche und einer Hülsenelement- fläche, welche von dem ersten bzw. dem zweiten Heizelement beheizt werden, in Kontakt. Dabei ist es vorteilhaft, dass der Durchflusskanalabschnitt von einem Profilkörper ausgebildet ist, der geometrisch gleich- mäßig und daher leicht zu reinigen ist. Ein Profilkörper weist keine Bögen oder Durchbrüche auf, in denen mögliche Ablagerungen nur umständlich zu entfernen wären und ist darüber hinaus einfach herzustellen sowie in beliebigen Längen erhältlich. Aufgrund der wirkungsvollen Beheizung kann der Durchflusskanal des Wärmeübertragers relativ kurz bemessen sein, ohne dass ein Heizelement in direkten Kontakt mit dem Medium gelangt. Auch kann es im Durchflusskanalabschnitt aufgrund der so ausgebildeten, gleichmäßigen Wärmeverteilung über die Wärmeübertragerflächen kaum zu einer lokalen Überhitzung des Mediums kommen. Die damit verbundenen negativen Effekte werden insbesondere dadurch vermieden, dass die Heizelemente nicht mit dem Medium in Kontakt gelangen können. Medium with a flow channel inner surface and a sleeve element surface, which are heated by the first and the second heating element, in contact. It is advantageous that the flow channel section is formed by a profile body which is geometrically uniform and therefore easy to clean. A profile body has none Arches or breakthroughs in which possible deposits would be awkward to remove and is also easy to manufacture and available in any length. Due to the effective heating of the flow channel of the heat exchanger can be made relatively short, without a heating element comes into direct contact with the medium. Also, it can hardly come to a local overheating of the medium in the flow channel section due to the thus formed, uniform heat distribution over the heat exchanger surfaces. The associated negative effects are avoided in particular by the fact that the heating elements can not come into contact with the medium.
Vorteilhaft kann der Wärmeübertrager eine Mehrzahl von parallel angeordneten Profilkörpern umfassen. So kann eine Durchflussmenge erhöht oder alternativ ein Durchflusskanalabschnitt verlängert werden. Der Wärmeübertrager kann dann insbesondere so ausgebildet sein, dass ein modularer Aufbau des Wärmeübertragers mit einer für den jeweiligen Anwendungsfall geeigneten Anzahl Profilköpern möglich ist. Eine Anpassung des Wärmeübertragers an spezielle Kundenwünsche oder Anforderungen wird damit ohne größeren Herstellungsaufwand einfach möglich. Advantageously, the heat exchanger may comprise a plurality of profile bodies arranged in parallel. Thus, a flow rate increased or alternatively a flow channel section can be extended. The heat exchanger can then be designed in particular so that a modular construction of the heat exchanger is possible with a number of profile bodies suitable for the respective application. An adaptation of the heat exchanger to specific customer requirements or requirements is thus easily possible without major manufacturing effort.
Der Wärmeübertrager kann weiter ein Deckelelement und ein Bodenelement umfassen, welche jeweils an Profilenden des Profilkörpers angeordnet sind. Mittels des Deckelelements und des Bodenelements können beispielsweise eine Mehrzahl von Profilkörpern zwischen dem Deckel- element und dem Bodenelement gehaltert werden. Auch kann das Deckelelement und das Bodenelement gegenüber den Profilenden so abgedichtet sein, dass das fließfähige Medium nicht in unerwünschter Weise aus dem Wärmeübertrager austreten kann. The heat exchanger may further comprise a cover element and a bottom element, which are each arranged at profile ends of the profile body. By means of the cover element and the floor element, for example, a plurality of profiled bodies can be held between the cover element and the floor element. Also, the lid member and the bottom member relative to the profile ends be sealed so that the flowable medium can not escape from the heat exchanger in an undesirable manner.
Auch können im Deckelelement und/oder im Bodenelement Anschlusska- näle des Durchflusskanals ausgebildet sein. Die Anschlusskanäle müssen dann nicht in einem oder mehreren Profilkörpern angeordnet werden, sondern können einfach, je nach Verwendungsanforderung des Wärmeübertragers, an den vorgenannten Elementen angeordnet sein. Ebenso können eine Mehrzahl von Anschlusskanälen an verschiedenen Seiten des Deckelelements und/oder des Bodenelements zur optionalen Verwendung vorgesehen sein. Die nicht verwendeten Anschlusskanäle können dann beispielsweise mit einer Verschraubung verschlossen sein. Also, connecting channels of the flow channel can be formed in the cover element and / or in the base element. The connection channels then do not have to be arranged in one or more profile bodies, but can be easily, depending on the application requirement of the heat exchanger, arranged on the aforementioned elements. Likewise, a plurality of connection channels may be provided on different sides of the cover element and / or the floor element for optional use. The unused connection channels can then be closed, for example with a screw.
Besonders vorteilhaft ist es, wenn im Deckelelement und/oder im Bodenelement zumindest ein Verbindungskanal zur Verbindung von Durchflusskanalabschnitten ausgebildet ist. Mehrere Durchflusskanalabschnitte können so in Reihe hintereinander verbunden werden. Die Anzahl derIt is particularly advantageous if at least one connecting channel for connecting flow channel sections is formed in the cover element and / or in the bottom element. Several flow channel sections can thus be connected in series one behind the other. The number of
Verbindungskanäle kann je nach Anzahl verwendeter Profilkörper variieren. Zur Ausbildung von Wärmeübertragern mit unterschiedlichen Wärmeleistungen bedarf es folglich alleine eines Austausches von Deckel- und/oder Bodenelementen mit der entsprechenden Anzahl gleichartiger Profilkörper. Connecting channels may vary depending on the number of profile bodies used. For the formation of heat exchangers with different heat outputs, therefore, it requires an exchange of cover and / or floor elements with the corresponding number of similar profile body alone.
Eine vorteilhafte Halterung des Hülsenelements wird möglich, wenn das Hülsenelement mit dem Deckelelement fest verbunden ist. Für eine Reinigung des Durchflusskanals muss dann lediglich das Deckelement vom Profilkörper demontiert werden, wobei das Deckelelement dann zusammen mit dem Hülsenelement vom Profilkörper bzw. aus dem An advantageous support of the sleeve member is possible when the sleeve member is firmly connected to the lid member. For cleaning the flow channel then only the cover element must be removed from the profile body, the cover element then together with the sleeve member from the profile body or from the
Durchflusskanalabschnitt entfernt wird. So ist die Hülsenelementfläche wie auch die Durchflusskanalinnenfläche leicht für eine Reinigung zugänglich. Vorzugsweise kann das erste Heizelement, welches in der Heizelementaufnahme des Profilkörpers angeordnet ist, dann ebenfalls mit dem Deckelelement in geeigneter Weise verbunden sein.  Flow channel section is removed. Thus, the sleeve element surface as well as the flow channel inner surface is easily accessible for cleaning. Preferably, the first heating element, which is arranged in the Heizelementaufnahme of the profile body, then also be connected to the cover member in a suitable manner.
Der Wärmeübertrager kann besonders einfach hergestellt werden, wenn der Durchflusskanalabschnitt und die Heizelementaufnahme als Durchgangsbohrungen im Profilelement in Längsrichtung des Profilelements ausgebildet sind. Um eine gegenüber einem konventionellen Heizelement stark vergrößerte Wärmeübertragerfläche auszubilden, kann das Hülsenelement einen polygonalen Querschnitt ausbilden. The heat exchanger can be produced particularly simply if the flow channel section and the heating element receptacle are formed as through-holes in the profile element in the longitudinal direction of the profile element. To form a compared to a conventional heating element greatly enlarged heat transfer surface, the sleeve member may form a polygonal cross-section.
Wenn das Hülsenelement auf seiner Umfangsfläche eine Vielzahl von auf dem Umfang verteilten Längsnuten aufweist, derart, dass das Hülsenelement einen sternförmigen Querschnitt ausbildet, kann eine Wärmeübertragerfläche bzw. Hülsenelementfläche noch weiter vergrößert werden. When the sleeve member has a plurality of circumferential grooves distributed on its peripheral surface, such that the sleeve member forms a star-shaped cross section, a heat transfer surface or sleeve member surface can be further increased.
Besonders große Wärmeübertragerflächen sind möglich, wenn ein Au- ßendurchmesser des Hülsenelements im Wesentlichen einem Innendurchmesser des Durchflusskanalabschnitts entspricht. Ein Durchflusskanalquerschnitt wird dann alleine von dem im Querschnitt ringförmigen Zwischenraum zwischen Durchflusskanalinnenfläche und Hülsenelementfläche ausgebildet. So kann auch zwischen dem Hülsenelement und dem Profilkörper eineParticularly large heat exchanger surfaces are possible if an outer diameter of the sleeve element essentially corresponds to an inner diameter of the flow channel section. A flow channel cross-section is then formed solely by the annular cross-sectional space between the flow channel inner surface and sleeve member surface. So can also between the sleeve member and the profile body a
Vielzahl von Teilkanälen des Durchflusskanalabschnitts ausgebildet sein. Wenn die Hülsenelementfläche zumindest abschnittsweise an der Durchflusskanalinnenfläche zur Anlage gelangt, wird darüber hinaus ein besonders guter Sitz des Hülsenelements im Durchflusskanalabschnitt sichergestellt. Be formed plurality of sub-channels of the flow channel section. If the sleeve element surface comes at least partially to the flow channel inner surface to the plant, beyond a particularly good fit of the sleeve member is ensured in the flow channel section.
In einer vorteilhaften Ausführungsform kann der Wärmeübertrager Heizelemente in einem Verhältnis von zwei zweiten Heizelementen zu einem ersten Heizelement aufweisen. In an advantageous embodiment, the heat exchanger may have heating elements in a ratio of two second heating elements to a first heating element.
Ein einfacher, gemeinsamer Anschluss aller Heizelemente an eine A simple, common connection of all heating elements to one
Stromversorgung bzw. Unterverteilung wird ermöglicht, wenn der Wärmeübertrager am Deckelelement eine Anschlusseinrichtung zum Anschluss der Heizelemente aufweist. Die Anschlusseinrichtung kann ein gegenüber einer Umgebung abgedichtetes Gehäuse mit Einrichtungen zur Unterverteilung für die elektrischen Heizelemente und Steuerungs- bzw. Regelungseinrichtungen umfassen. Power supply or sub-distribution is made possible when the heat exchanger has a connection device for connecting the heating elements on the cover element. The connection device may be an environmentally sealed housing with means for Subdistribution for the electrical heating elements and control devices include.
Zur Ausbildung einer Temperaturregelung kann zumindest ein Temperatursensor im Durchflusskanal angeordnet sein. Optional können mehrere Temperatursensoren vorgesehen sein, um eine Temperaturdifferenz entlang des Durchflusskanals zu ermitteln. Vorzugsweise kann eine Temperaturregelung auf Basis von Messwerten des Temperatursensors mit einer SPS-Steuerung erfolgen. To form a temperature control, at least one temperature sensor can be arranged in the flow channel. Optionally, a plurality of temperature sensors may be provided to determine a temperature difference along the flow channel. Preferably, a temperature control can be carried out on the basis of measured values of the temperature sensor with a PLC control.
Der Durchflusskanal selbst kann mäanderförmig ausgebildet sein, bei- spielsweise durch in Reihe hintereinander angeordneter Durchflusskanalabschnitte, die über Verbindungskanäle verbunden sind. So kann besonders einfach eine kompakte Ausführung eines Wärmeübertragers ausgebildet werden. The flow channel itself may be formed meander-shaped, for example by flow channel sections arranged in series one behind the other, which are connected via connecting channels. Thus, a compact design of a heat exchanger can be formed in a particularly simple manner.
Vorteilhaft kann der Wärmeübertrager eine Isolationseinrichtung aufwei- sen, die mögliche Wärmeverluste an eine Umgebung minimiert. Weiter kann die Isolationseinrichtung Bedienpersonal vor möglichen Verbrennungen schützen. Advantageously, the heat exchanger can have an insulation device which minimizes possible heat losses to an environment. Furthermore, the isolation device can protect operating personnel from possible burns.
Im Folgenden wird die Erfindung unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert. Es zeigen: In the following the invention will be explained in more detail with reference to the accompanying drawings. Show it:

Weiter sind in den Durchflusskanalabschnitten jeweils Hülsenelementen 17 angeordnet, die einen sternförmigen Profilquerschnitt 18 aufweisen, so dass zwischen einer Durchflusskanalinnenfläche 19 und einer Hülsenelementfläche 20 eine Vielzahl von Teil- kanälen 21 ausgebildet werden. Weiter umfasst der Wärmübertrager 10 erste Heizelemente 22, welche in einer im Profilkörper 1 1 bzw. 12 ausgebildeten Heizelementaufnahme 23 , welche in Art einer Durchgangsbohrung ausgebildet ist, angeordnet sind. In den Hülsenelementen 17 sind zweite Heizelemente 24 in ebenfalls als Durchgangsbohrung ausgebildeten Heizelementaufnahmen 25 angeordnet. Die ersten Heizelemente 22 und zweiten Heizelemente 24 sind jeweils so in den Heizelementaufnahmen 23 bzw. 25 angeordnet, dass ein Berührungskontakt für einen besonders guten Wärmeübergang zwischen den ersten Heizelementen 22 und den Profilkörpern 1 1 bzw. 12 sowie zwischen den zweiten Heizelementen 24 und den Hülsenelementen 17 besteht. Um ein Eindringen von einem hier nicht gezeigten fließfähigem Medium in die Heizelementaufnahme 25 zu verhindern, ist an einem unteren Ende 26 des Hülsenelements 17 jeweils eine abdichtende Schraube 27 in das Hülsenelement 17 eingeschraubt. Weiter umfasst der Wärmeübertrager 10 ein Deckelelement 28 und ein Bodenelement 29, welche an Profilenden 30 bis 33 der Profilkörper 1 1 bzw. 12 angeordnet und mit diesen mittels Schrauben 34 fest verschraubt sind. Im Bodenelement 29 sind weiter zwei Verbindungskanäle 35 und 36 in Art einer Querbohrung ausgebildet und jeweils mit einer Schraube 37 verschlossen. Der Verbindungskanal 35 verbindet die Durchflusskanalabschnitte 13 und 15 bzw. der Verbindungskanal 36 die Durchflusskanalabschnitte 14 und 16. Im Deckelelement 28 ist ebenfalls ein Verbindungskanal 38 mit einer Schraube 37 vorgesehen, welcher die Durchflusska- nalabschnitte 13 und 14 verbindet. Weiter sind im Deckelelement 28A synopsis of FIGS. 1 to 6 shows a heat exchanger 10 in different, perspective representations and sections. The heat exchanger comprises two profile bodies 1 1 and 12, which form flow channel sections 13 and 14 or 15 and 16 in the manner of a through-bore. Further, sleeve elements 17 are arranged in the flow channel sections, which have a star-shaped profile cross section 18, so that between a flow channel inner surface 19 and a sleeve member surface 20, a plurality of sub-channels 21 are formed. Furthermore, the heat exchanger 10 comprises first heating elements 22, which are arranged in a heating element receptacle 23 formed in the profile body 11 or 12, which is constructed in the manner of a through-bore. In the sleeve members 17 second heating elements 24 are arranged in also formed as a through hole heating element receptacles 25. The first heating elements 22 and second heating elements 24 are each arranged in the Heizelementaufnahmen 23 and 25, that a touch contact for a particularly good heat transfer between the first heating elements 22 and the profile bodies 1 1 and 12 and between the second heating elements 24 and the sleeve elements 17 exists. In order to prevent penetration of a flowable medium, not shown here in the Heizelementaufnahme 25, a sealing screw 27 is screwed into the sleeve member 17 at a lower end 26 of the sleeve member 17 respectively. Furthermore, the heat exchanger 10 comprises a cover element 28 and a bottom element 29, which are arranged on profile ends 30 to 33 of the profile body 1 1 and 12 and are screwed firmly to them by means of screws 34. In the bottom member 29 further two connecting channels 35 and 36 are formed in the manner of a transverse bore and each closed with a screw 37. The connecting channel 35 connects the flow channel sections 13 and 15 or the connecting channel 36, the flow channel sections 14 and 16. In the cover member 28, a connecting channel 38 is also provided with a screw 37 which connects the flow channel sections 13 and 14. Next are in the lid member 28th
Anschlusskanäle 39 und 40 in Art einer Bohrung ausgebildet, die mit den Durchflusskanalabschnitten 15 bzw. 16 verbunden sind. In die Anschlusskanäle 39 und 40 sind Anschlussverschraubungen 41 zum An- schluss des Wärmeübertragers 10 an eine hier nicht dargestellte Zu- bzw. Ableitung eines Spritzgerätes eingeschraubt. Insgesamt ergibt sich durch die Relativanordnung der Durchflusskanalabschnitte 13 bis 16 und der Verbindungskanäle 35 , 36 und 38 eine mäanderförmige Ausbildung eines Durchflusskanals 42. Port channels 39 and 40 formed in the manner of a bore, which are connected to the flow channel sections 15 and 16, respectively. In the connection channels 39 and 40 are screwed connection fittings 41 for connection of the heat exchanger 10 to a supply or discharge of a spray device not shown here. Overall, results from the relative arrangement of the flow channel sections 13 to 16 and the connecting channels 35, 36 and 38, a meandering formation of a flow channel 42nd
Zur Abdichtung des Deckelelements 28 und des Bodenelements 29 mit den Profilkörpern 1 1 bzw. 12 sind Dichtungen 43 an den Profilenden 30 bis 33 angeordnet. Weiter sind die Hülsenelemente 17 an ihren oberen Enden 44 mit einer Umfangsnut 45 und einem Gewinde 46 versehen. Die Hülsenelemente 17 sind so mittels des Gewindes 46 in das Deckelelement 28 fest eingeschraubt. Die Umfangsnut 45 dient im Wesentlichen einer verbesserten Verteilung des zu erwärmenden Mediums. To seal the lid member 28 and the bottom member 29 with the profile bodies 1 1 and 12, seals 43 are arranged on the profile ends 30 to 33. Further, the sleeve members 17 are provided at their upper ends 44 with a circumferential groove 45 and a thread 46. The sleeve members 17 are screwed firmly by means of the thread 46 in the cover member 28. The circumferential groove 45 essentially serves to improve the distribution of the medium to be heated.
Am Deckelelement 28 ist weiter eine Anschlusseinrichtung 47 mit einem Anschlussgehäuse 48 und einer Anschlussklemme 49 angeordnet. Die Anschlussklemme 49 dient im Wesentlichen dem elektrischen Anschluss der ersten Heizelemente 22 und zweiten Heizelemente 24 an eine zentra- Ie Stromversorgung. Das Anschlussgehäuse 48 ist aus einem Gehäusering 50 mit einem Gehäusedeckel 51 gebildet, welche mit dem Deckelelement 28 so verbunden sind, dass ein dichter Anschlussraum 52 gebildet wird. A connection device 47 with a connection housing 48 and a connection terminal 49 is furthermore arranged on the cover element 28. The connection terminal 49 essentially serves for the electrical connection of the first heating elements 22 and second heating elements 24 to a central power supply. The connection housing 48 is made of a housing ring 50 are formed with a housing cover 51, which are connected to the cover member 28 so that a sealed connection space 52 is formed.
Im Anschlusskanal 39 bzw. im Deckelelement 28 ist ein Temperatursensor 53 und im Profilkörper 12 bzw. im Durchflusskanalabschnitt 15 ein Temperatursensor 54 angeordnet. Beide Temperatursensoren 53 und 54 sind mit einer hier nicht gezeigten SPS-Steuerung zur Regelung der Temperatur verbunden. In the connection channel 39 or in the cover element 28, a temperature sensor 53 and in the profile body 12 or in the flow channel section 15, a temperature sensor 54 is arranged. Both temperature sensors 53 and 54 are connected to a PLC, not shown here for controlling the temperature.
Für eine Demontage zur Reinigung des Wärmeübertragers 10 ist es lediglich notwendig, die Schrauben 34 aus dem Deckelelement 28 zu entfernen und das Deckelelement 28 so von den Profilkörpern 1 1 und 12 zu trennen, wobei die Hülsenelemente 17 aus den Durchflusskanalabschnitten 13 bis 16 dann herausgezogen werden können. Die Durchflusskanalinnenfläche 19 kann nun einfach mechanisch gereinigt werden, wobei bei Bedarf auch das Bodenelement 29 durch Lösen der Schrauben 34 einfach von den Profilkörpern 1 1 und 12 entfernt werden kann. Die dann freiliegende Hülsenelementfläche 20 kann ebenfalls leicht gereinigt werden. For a disassembly for cleaning the heat exchanger 10, it is only necessary to remove the screws 34 from the lid member 28 and the lid member 28 so separated from the profile bodies 1 1 and 12, wherein the sleeve members 17 are then pulled out of the flow channel sections 13 to 16 can. The flow channel inner surface 19 can now be easily cleaned mechanically, wherein if necessary, the bottom member 29 can be easily removed by loosening the screws 34 of the profile bodies 1 1 and 12. The then exposed sleeve member surface 20 can also be easily cleaned.
