Description

Wärmetauscher für ein Kältegerät Heat exchanger for a refrigeration device
Die vorliegende Erfindung betrifft einen Wärmetauscher mit einer Grundplatte, einer an der Grundplatte befestigten Rohrleitung für ein Kältemittel und einer an der Grundplatte angeordneten Hülse zum Aufnehmen eines Temperaturfühlers sowie ein Kältegerät, das mit einem solchen Wärmetauscher ausgestattet ist. Ein solcher Wärmetauscher kann in einer Kältemaschine als Verflüssiger, insbesondere aber als Verdampfer zum Einsatz kommen.The present invention relates to a heat exchanger with a base plate, a pipe for a refrigerant fastened to the base plate and a sleeve arranged on the base plate for receiving a temperature sensor, and to a refrigeration device which is equipped with such a heat exchanger. Such a heat exchanger can be used in a refrigerator as a condenser, but in particular as an evaporator.
Um den Betrieb eines solchen Verdampfers temperaturgesteuert zu regeln, wird im Allgemeinen an dem Verdampfer ein Temperaturfühler montiert, der mit einer Thermostatregelschaltung verbunden ist. Diese Thermostatregelschaltung schaltet die Kältemaschine so ein und aus, dass die vom Temperaturfühler erfasste Temperatur in einem Sollbereich bleibt. Die vom Temperaturfühler erfasste Temperatur weist im Allgemeinen systematische Abweichungen von der tatsächlichen Temperatur des Verdampfers auf und folgt deren Änderungen mit Verzögerung. Diese systematischen Abweichungen hängen unter anderem ab von der Wärmeleitfähigkeit des Übergangs vom Verdampfer zum Temperaturfühler, von der Entfernung des Temperaturfühlers von der Kältemittelleitung des Verdampfers etc..In order to control the operation of such an evaporator in a temperature-controlled manner, a temperature sensor is generally mounted on the evaporator and is connected to a thermostat control circuit. This thermostat control circuit switches the chiller on and off in such a way that the temperature detected by the temperature sensor remains in a target range. The temperature detected by the temperature sensor generally shows systematic deviations from the actual temperature of the evaporator and follows their changes with delay. These systematic deviations depend, among other things, on the thermal conductivity of the transition from the evaporator to the temperature sensor, on the distance of the temperature sensor from the refrigerant line of the evaporator, etc.
Um ein einheitliches Regelverhalten von in Serie produzierten Wärmetauschern zu gewährleisten, muss die Hülse, die vorgesehen ist, um, wenn der Verdampfer in einem Kältegerät montiert ist, den Temperaturfühler aufzunehmen, bei jedem Verdampfer die gleiche Position in Bezug auf die sich entlang der Verdampferplatte erstreckenden Kältemittelleitung haben. Bei Rollbond-Verdampfern kann die reproduzierbare Positionierung der Hülse in Bezug auf den Verlauf der Kältemittelleitung auf einfache Weise sichergestellt werden, indem in einem der zwei einander zu befestigenden Bleche eines solchen Verdampfers ein Kältemittelkanal und ein Kanal zum Aufnehmen eines Temperaturfühlers gemeinsam geprägt werden. Eine solche Technik ist z.B. aus DE 39 28 471 C2 bekannt. Sie ist jedoch nicht auf Rohr-Platten-Verdampfer übertragbar, d.h. auf Verdampfer, die aufgebaut sind aus einer Verdampferplatte, an deren Oberfläche eine Rohrleitung für das Kältemittel befestigt ist. Bei solchen Verdampfern ist es zwar möglich, einen Kanal zum späteren Aufnehmen eines Temperaturfühlers, z.B. in Form eines Blech- oder Kunststoffrohrs, anzukleben, dies kann jedoch nicht in einem Arbeitsgang zusammen mit der Anbringung des Kältemittelrohrs erfolgen, so dass eine reproduzierbare Positionierung eines solchen Kanals in Bezug auf das Kältemittelrohr und damit ein einheitliches Regelverhalten nicht ohne weiteres gewährleistet ist.In order to ensure a uniform control behavior of heat exchangers produced in series, the sleeve which is provided in order to accommodate the temperature sensor when the evaporator is installed in a refrigeration device must be in the same position with respect to those extending along the evaporator plate Have a refrigerant line. In Rollbond evaporators, the reproducible positioning of the sleeve with respect to the course of the refrigerant line can be ensured in a simple manner by co-embossing a refrigerant channel and a channel for receiving a temperature sensor in one of the two sheets of such an evaporator to be fastened to one another. Such a technique is known for example from DE 39 28 471 C2. However, it cannot be transferred to tube-plate evaporators, ie to evaporators which are constructed from an evaporator plate, on the surface of which a pipe for the refrigerant is attached. With such evaporators, it is possible to glue a channel for later accommodation of a temperature sensor, e.g. in the form of a sheet metal or plastic tube, but this cannot be done in one operation together with the attachment of the refrigerant tube, so that such a channel can be positioned in a reproducible manner with regard to the refrigerant pipe and thus a uniform control behavior is not easily guaranteed.
Eine andere Möglichkeit ist, einen Kanal zu bilden, indem ein Randabschnitt der Grundplatte zu einem Kanal für den Temperaturfühler zusammengerollt wird. Auf diese Weise ist zwar die Position des Temperaturfühlers in Bezug auf die Grundplatte festgelegt, doch ist man so darauf eingeschränkt, dass der Temperaturfühler nur am Rand der Grundplatte positioniert werden kann, also in einem Bereich, der relativ starken störenden thermischen Einflüssen von außen ausgesetzt ist und dessen Temperatur somit nur eingeschränkt einen Rückschluss auf die mittlere Temperatur der Grundplatte erlaubt.Another possibility is to form a channel by rolling an edge section of the base plate into a channel for the temperature sensor. In this way, the position of the temperature sensor in relation to the base plate is fixed, but it is restricted to the fact that the temperature sensor can only be positioned at the edge of the base plate, i.e. in an area that is exposed to relatively strong disturbing thermal influences from the outside and its temperature thus allows only a limited conclusion about the average temperature of the base plate.
Aufgabe der vorliegenden Erfindung ist, einen Wärmetauscher für ein Kältegerät in Rohr- Platten-Technik zu schaffen, der eine reproduzierbare Positionierung einer Aufnahmehülse für einen Temperaturfühler auf einfache Weise und ohne die Notwendigkeit einer Positionsmessung oder -justage erlaubt.The object of the present invention is to provide a heat exchanger for a refrigeration device in tube-plate technology, which allows reproducible positioning of a receiving sleeve for a temperature sensor in a simple manner and without the need for position measurement or adjustment.
Die Aufgabe wird gelöst durch einen Wärmetauscher mit den Merkmalen des Anspruchs 1. Indem bei diesem Wärmetauscher die Hülse der Oberfläche der Verdampferplatte durch wenigstens eine an der Rohrleitung angreifende Strebe fixiert ist, ist die Position der Hülse genau festgelegt auf einen Abstand zu der Rohrleitung, der der Länge der Strebe entspricht. So ist die Verzögerung, mit der ein in der Hülse montierter Temperaturfühler eine Erwärmung oder Abkühlung der Kältemittelleitung registriert, für alle in Serie gefertigten Verdampfer mit gleicher Länge der Strebe einheitlich.The object is achieved by a heat exchanger having the features of claim 1. Since in this heat exchanger the sleeve of the surface of the evaporator plate is fixed by at least one strut engaging the pipe, the position of the sleeve is precisely defined at a distance from the pipe which corresponds to the length of the strut. The delay with which a temperature sensor installed in the sleeve registers heating or cooling of the refrigerant line is uniform for all series-produced evaporators with the same length of the strut.
Die Montage des Wärmetauschers ist vereinfacht, wenn jede Strebe einen Klammerabschnitt zum Anklemmen an der Rohrleitung aufweist. Dies ermöglicht eine schnelle vorläufige Fixierung der Hülse an der Grundplatte; eine definitive Fixierung, insbesondere durch Abdecken der die Rohrleitung und die Hülse tragenden Seite der Grundplatte durch eine Deckschicht oder -folie, kann zu einem späteren Zeitpunkt erfolgen.The assembly of the heat exchanger is simplified if each strut has a clamp section for clamping on the pipeline. This enables a quick provisional fixation of the sleeve on the base plate; a definitive fixation, in particular by covering the side of the pipe and the sleeve carrying the Base plate through a cover layer or film, can be done at a later date.
Einer ersten bevorzugten Ausgestaltung zufolge sind die Hülse und die wenigstens eine Strebe einteilig ausgebildet, und zwar vorzugsweise aus einem Zuschnitt aus einem Flachmaterial wie insbesondere Metallblech.According to a first preferred embodiment, the sleeve and the at least one strut are formed in one piece, preferably from a blank made of a flat material such as, in particular, sheet metal.
Einer zweiten bevorzugten Ausgestaltung zufolge ist die Strebe als ein von der Hülse getrenntes Teil realisiert und an dieser angeklemmt. Eine solche Strebe kann insbesondere einem ersten Klammerabschnitt zum Anklemmen an der Rohrleitung und einen zweiten Klammerabschnitt zum Anklemmen an der Hülse aufweisen.According to a second preferred embodiment, the strut is realized as a part separate from the sleeve and clamped on it. Such a strut can have, in particular, a first clamp section for clamping on the pipeline and a second clamp section for clamping on the sleeve.
Um eine Verkippung der Hülse in Bezug auf die Kältemittelleitung zu vermeiden, an der sie fixiert ist, sind der Hülse vorzugsweise wenigstens zwei Streben zugeordnet.In order to prevent the sleeve from tilting with respect to the refrigerant line to which it is fixed, the sleeve is preferably assigned at least two struts.
Diese zwei Streben können sich von der Hülse aus in eine gleiche Richtung erstrecken, um insbesondere an einem gleichen, parallel zu der Hülse verlaufenden geradlinigen Rohrabschnitt anzugreifen, sie können sich aber auch von der Hülse aus in entgegengesetzte Richtungen erstrecken, um an zwei verschiedenen, sich beiderseits der Hülse erstreckenden Abschnitten der Rohrleitung anzugreifen.These two struts can extend in the same direction from the sleeve, in particular to engage a same straight pipe section running parallel to the sleeve, but they can also extend in opposite directions from the sleeve in order to engage two different ones to attack on both sides of the sleeve extending sections of the pipeline.
Um die Montageposition der Hülse auch in Längsrichtung der Rohrleitung zu fixieren, kann vorgesehen werden, dass die Rohrleitung am Angriffspunkt wenigstens einer Strebe eine Markierung trägt. Bei einer solchen Markierung kann es sich insbesondere um eine Kerbe oder Einbuchtung handeln, die im Laufe der Befestigung der Rohrleitung an der Verdampferplatte an einem vorgegebenen Ort in die Rohrleitung eingedrückt worden ist, und in die der Klammerabschnitt der Strebe einrasten kann, so dass er gegen ein Verrutschen in Längsrichtung der Rohrleitung gesichert ist.In order to fix the assembly position of the sleeve also in the longitudinal direction of the pipeline, it can be provided that the pipeline bears a marking at the point of application of at least one strut. Such a marking can be, in particular, a notch or indentation which has been pressed into the pipeline at a predetermined location in the course of the fastening of the pipeline to the evaporator plate, and into which the clamp section of the strut can snap, so that it can engage against slipping in the longitudinal direction of the pipeline is ensured.
Die Rohrleitung und die Hülse können auf einfache Weise durch eine Klebeschicht mit der Verdampferplatte verbunden sein. Vorzugsweise sind die Rohrleitung und die Hülse zwischen der Verdampferplatte einerseits und einer Folie aus verformbarem Material wie etwa Bitumen, Kunststoffmaterial oder Aluminium andererseits eingeschlossen.The pipeline and the sleeve can be connected to the evaporator plate in a simple manner by means of an adhesive layer. The pipeline and the sleeve are preferably enclosed between the evaporator plate on the one hand and a film of deformable material such as bitumen, plastic material or aluminum on the other hand.

Der in Fig. 1 in perspektivischer Ansicht gezeigte, als Verdampfer für ein Kältegerät vorgesehene Wärmetauscher ist aufgebaut aus einer ebenen Grundplatte 1 aus Aluminiumblech, auf der eine Kältemittelleitung 2 aus einem ebenfalls aus Aluminium bestehenden Rohr mäanderförmig angeordnet ist. Die Grundplatte 1 und die Kältemittelleitung 2 sind überdeckt von einer Haltematerialschicht 3, die z.B. aus einem Gemisch aus Bitumen, Zuschlagstoffen zum Einstellen einer gewünschten Wärmekapazität und/oder Wärmelleitfähigkeit der Haltematerialschicht 3 und eventuell weiteren die Verarbeitbarkeit der Schicht 3 beeinflussenden Zusätzen besteht. Dabei kann der Anteil des Bitumens an der Schicht 3 kleiner sein als der der Zuschlagstoffe. Anstelle von Bitumen könnte die Haltematerialschicht 3 auch aus einem Kunststoffmaterial wie etwa Polyethylen, gegebenenfalls mit entsprechenden Zuschlagsstoffen, oder aus einer starken Aluminiumfolie bestehen.The heat exchanger shown in FIG. 1 as a evaporator for a refrigeration device is constructed from a flat base plate 1 made of aluminum sheet, on which a refrigerant line 2 made of a tube also made of aluminum is arranged in a meandering shape. The base plate 1 and the refrigerant line 2 are covered by a holding material layer 3, which consists, for example, of a mixture of bitumen, additives for setting a desired heat capacity and / or thermal conductivity of the holding material layer 3 and possibly other additives influencing the processability of layer 3. there the proportion of bitumen in layer 3 can be smaller than that of the additives. Instead of bitumen, the holding material layer 3 could also consist of a plastic material such as polyethylene, possibly with appropriate additives, or of a strong aluminum foil.
Wie der Querschnitt der Fig. 2 zeigt, erstreckt sich die Haltematerialschicht 3 bis in die Zwickel 4 hinein, die beiderseits der Kontaktlinie zwischen der Kältemittelleitung 2 und der Grundplatte 1 liegen und trägt so wesentlich zu einem effizienten Wärmeübergang zwischen der Grundplatte 1 und der Kältemittelleitung 2 bei. Um die Dicke der Haltematerialschicht 3 in den Zwickeln 4 zu minimieren und so den Wärmeübergang weiter zu verbessern, hat die Kältemittelleitung 2 einen abgeflacht elliptischen Querschnitt, der z.B. erhalten werden kann, indem eine ursprünglich runde Kältemittelleitung nach dem Verlegen auf der Grundplatte 1 oder während des Verlegens an dieser flachgedrückt wird.As the cross section of FIG. 2 shows, the holding material layer 3 extends into the gussets 4, which are located on both sides of the contact line between the refrigerant line 2 and the base plate 1, and thus contributes significantly to efficient heat transfer between the base plate 1 and the refrigerant line 2 at. In order to minimize the thickness of the holding material layer 3 in the gussets 4 and thus further improve the heat transfer, the refrigerant line 2 has a flattened elliptical cross section, which e.g. can be obtained by pressing an originally round refrigerant line after laying on the base plate 1 or during laying on this.
Zwischen der Haltematerialschicht 3 und der Kältemittelleitung 2 einerseits und der Grundplatte 1 andererseits befindet sich eine Schicht 5 aus einem Heißkleber, die wegen ihrer im Vergleich zur Grundplatte 1 und der Haltematerialschicht 3 wesentlich geringeren Dicke in der Figur lediglich als Linie erkennbar ist.Between the holding material layer 3 and the refrigerant line 2, on the one hand, and the base plate 1, on the other hand, there is a layer 5 made of a hot-melt adhesive, which is only recognizable as a line in the figure because of its much smaller thickness compared to the base plate 1 and the holding material layer 3.
Ein Kanal 6 zum Aufnehmen eines Temperaturfühlers ist in einem Zwischenraum zwischen zwei parallelen Abschnitten der Kältemittelleitung 2 parallel zu diesen angeordnet. Der Kanal 6 ist gebildet durch eine aus einem Blechzuschnitt gerollte Hülse 7, die in Fig. 2 im Schnitt und in Fig. 3 in einer perspektivischen Ansicht gezeigt ist. Der Blechzuschnitt, aus dem die Hülse 7 geformt ist, hat die Form eines doppelten Ts (oder des griechischen Buchstaben π), wobei die Querbalken der zwei Ts zur Hülse 7 aufgerollt sind und die Beine zwei Streben 8 bilden, die die Hülse 7 in einem vorgegebenen Abstand zu einem Abschnitt der Kältemittelleitung 2 parallel zu dieser halten. Die Streben 8 weisen jeweils einen geradlinigen Zwischenabschnitt 10 auf, der beim fertig montierten Wärmetauscher an der Heißkleberschicht 5 haftet, und an diesen anschließend einen Klammerabschnitt 9 in Form eines umgekehrten U, dessen zwei Schenkel auf die Kältemittelleitung 2 aufgeklemmt und dabei elastisch verformt sind. Diese Form der Hülse 7 erlaubt es, sie beim Zusammenbau des Wärmetauschers in einer durch die Länge des Zwischenabschnitts 10 fest vorgegebenen Entfernung von der Kältemittelleitung 2 zu platzieren, ohne dass hierfür aufwendig Maß genommen werden muss. Der Klammerabschnitt 9 sorgt für einen provisorischen Halt der Hülse 7 an der Platine während des Zusammenbaus, bevor die Haltematerialschicht 3 platziert und die Heißkleberschicht 5 erhitzt worden ist, um das Haltematerial mit der Grundplatte 1 zu verbinden.A channel 6 for receiving a temperature sensor is arranged in a space between two parallel sections of the refrigerant line 2 parallel to the latter. The channel 6 is formed by a sleeve 7 rolled from a sheet metal blank, which is shown in section in FIG. 2 and in a perspective view in FIG. 3. The sheet metal blank from which the sleeve 7 is formed has the shape of a double Ts (or the Greek letter π), the crossbars of the two Ts being rolled up to the sleeve 7 and the legs forming two struts 8 which form the sleeve 7 in one Keep the predetermined distance to a section of the refrigerant line 2 parallel to this. The struts 8 each have a rectilinear intermediate section 10, which adheres to the hot-glue layer 5 when the heat exchanger is fully assembled, and to this subsequently a clamp section 9 in the form of an inverted U, the two legs of which are clamped onto the refrigerant line 2 and thereby elastically deformed. This shape of the sleeve 7 allows it to be removed from the refrigerant line 2 when the heat exchanger is assembled at a fixed distance determined by the length of the intermediate section 10 place without having to take expensive measures. The clamp section 9 provides a temporary hold of the sleeve 7 on the circuit board during assembly before the holding material layer 3 has been placed and the hot-melt layer 5 has been heated in order to connect the holding material to the base plate 1.
Eine provisorische Halterung der Hülse 7 an der Kältemittelleitung 2 kann natürlich auch mit einer einzelnen Strebe 8 erreicht werden. Wenn die Breite einer solchen einzelnen Strebe die gleiche wäre wie der Abstand zwischen den zwei von einander abgewandten Längskanten der Streben 8 in Fig. 3, könnte auch die gleiche Genauigkeit der Parallelausrichtung der Hülse 7 zur Kältemittelleitung 2 wie mit zwei Streben erzielt werden. Dennoch ist die Verwendung von zwei parallelen Streben 8 bevorzugt, da in dem Zwischenraum zwischen den zwei Streben 8 die Haltematerialschicht 3 an der Heißkleberschicht 5 verklebt werden kann.A provisional retention of the sleeve 7 on the refrigerant line 2 can of course also be achieved with a single strut 8. If the width of such a single strut were the same as the distance between the two opposite longitudinal edges of the struts 8 in FIG. 3, the same accuracy of the parallel alignment of the sleeve 7 to the refrigerant line 2 could be achieved as with two struts. Nevertheless, the use of two parallel struts 8 is preferred since the holding material layer 3 can be glued to the hot-melt layer 5 in the space between the two struts 8.
Um die Position der Hülse 7 auch in Längsrichtung der Kältemittelleitung 2 festzulegen, sind in diese vorzugsweise an ihrer von der Grundplatte 1 abgewandten Seite zwei Vertiefungen (nicht dargestellt) eingedrückt, deren Breite jeweils der Breite einer Strebe 8 entspricht und deren Abstand voneinander dem Abstand der Streben 8 voneinander entspricht. Diese zwei Vertiefungen können als Referenz für die Platzierung der Hülse 7 dienen.In order to determine the position of the sleeve 7 also in the longitudinal direction of the refrigerant line 2, two depressions (not shown) are preferably pressed into it on its side facing away from the base plate 1, the width of which corresponds to the width of a strut 8 and the distance from one another is the distance between the two Struts 8 correspond to each other. These two depressions can serve as a reference for the placement of the sleeve 7.
Eine zweite Ausgestaltung des erfindungsgemäßen Wärmetauschers wird anhand der Figs. 4 bis 6 erläutert, die jeweils zu den Figs. 1 bis 3 analoge Ansichten zeigen. Auch hier ist die Hülse 7 mit Hilfe von zwei Streben 8 an der Kältemittelleitung 2 festgeklemmt, allerdings erstrecken sich die zwei Streben 8 von der Hülse 7 aus in jeweils entgegengesetzte Richtungen und greifen an zwei zueinander parallelen Abschnitten der Kältemittelleitung 2 an. Der Aufbau der Streben 8 mit Zwischenstück 10 und Klammerabschnitt 9 ist der gleiche wie bei der ersten Ausgestaltung. Durch die Verklammerung an zwei parallelen Abschnitten der Kältemittelleitung 2 gleichzeitig wird verhindert, dass sich die Hülse 7 im Laufe der Montage wieder löst, wenn vor dem Festkleben die Grundplatte 1 gekippt wird. Eine Variante dieser zweiten Ausgestaltung ist in Fig. 7 gezeigt. Anders als bei den zuvor beschriebenen Ausgestaltungen sind hier die Hülse 7 und die Streben 8 nicht einteilig aus Blech gebogen, sondern die Hülse ist durch ein Rohrstück 11 gebildet, welches durch einen Federblechstreifen 12 gegen die Platine 1 gedrückt gehalten ist, in welchem die zwei an der Kältemittelleitung 2 angreifenden Streben 8 ausgebildet sind.A second embodiment of the heat exchanger according to the invention is shown in FIGS. 4 to 6 explained, each of the Figs. 1 to 3 show analog views. Here, too, the sleeve 7 is clamped to the refrigerant line 2 with the aid of two struts 8, but the two struts 8 extend from the sleeve 7 in opposite directions and engage two mutually parallel sections of the refrigerant line 2. The structure of the struts 8 with the intermediate piece 10 and the clamp section 9 is the same as in the first embodiment. The clipping on two parallel sections of the refrigerant line 2 at the same time prevents the sleeve 7 from loosening again in the course of the assembly if the base plate 1 is tilted before the sticking. A variant of this second embodiment is shown in FIG. 7. In contrast to the configurations described above, the sleeve 7 and the struts 8 are not bent in one piece from sheet metal, but the sleeve is formed by a tube piece 11 which is held against the board 1 by a spring sheet metal strip 12, in which the two are attached the struts 8 attacking the refrigerant line 2 are formed.
Die Länge der Hülse richtet sich bei allen Ausgestaltungen nach der Länge eines in ihr unterzubringenden Temperaturfühlers; diese beträgt herkömmlicherweise ca. 160 mm.In all configurations, the length of the sleeve depends on the length of a temperature sensor to be accommodated in it; this is usually approx. 160 mm.
Auch der Zusammenbau des Wärmetauschers ist bei den drei betrachteten Ausgestaltung weitgehend gleiche. Nachdem die Hülse an der Kältemittelleitung 2 festgeklemmt worden ist, wird eine Folie auf die Anordnung aus Platine 1 , Kältemittelleitung 2 und Hülse 7 aufgelegt, die vorgesehen ist, um die Haltematerialschicht 3 zu bilden. Mit Hilfe eines Stempels, in dem Aussparungen entsprechend dem Verlauf der Kältemittelleitung 2 auf der Platine 1 und der Form der Hülse 7 gebildet sind, wird die Folie gegen die Heißkleberschicht 5 gedrückt und gleichzeitig erhitzt, um den Heißkleber zu aktivieren und so die Folie wie auch die Zwischenstücke 10 der Streben zu verkleben. Wenn das Material der Folie bei der Aktivierungstemperatur der Heißkleberschicht 5 weich wird und eine ausreichende Dicke hat, kann darüber hinaus ein hydrostatischer Druck auf die Folie ausgeübt werden, um Material der Folie dazu zu veranlassen, in die Zwickel 4 zwischen der Kältemittelleitung 2 und der Platine 1 einzudringen. Um den Temperaturfühler in der Hülse montieren zu können, genügt es, die Haltematerialschicht 3 an einem Ende der Hülse aufzuschneiden; es kann aber auch zum Anpressen der Folie ein Stempel verwendet werden, der so geformt ist, dass er die Folie an einem Ende der Hülse zum Aufreißen bringt. The assembly of the heat exchanger is largely the same in the three considered configurations. After the sleeve has been clamped to the refrigerant line 2, a film is placed on the arrangement of the circuit board 1, the refrigerant line 2 and the sleeve 7, which is provided to form the holding material layer 3. With the help of a stamp in which recesses are formed in accordance with the course of the refrigerant line 2 on the circuit board 1 and the shape of the sleeve 7, the film is pressed against the hot-melt layer 5 and at the same time heated to activate the hot-melt adhesive and so the film as well to glue the intermediate pieces 10 of the struts. In addition, if the material of the film softens and has a sufficient thickness at the activation temperature of the hot-melt layer 5, hydrostatic pressure can be exerted on the film to cause material of the film to enter the gusset 4 between the refrigerant line 2 and the circuit board 1 penetrate. In order to be able to mount the temperature sensor in the sleeve, it is sufficient to cut open the holding material layer 3 at one end of the sleeve; however, a stamp can also be used to press the film, which is shaped in such a way that it tears the film at one end of the sleeve.
