- Another possibility is to form a channel by curling a peripheral portion of the base plate into a channel for the temperature sensor.
- the position of the temperature sensor is fixed with respect to the base plate, but it is limited to the fact that the temperature sensor can only be positioned at the edge of the base plate, ie in an area that is exposed to relatively strong interfering thermal influences from the outside and whose temperature thus allows only a limited conclusion on the average temperature of the base plate.

- the pipeline carries a marking at the point of application of at least one strut.
- a marking may be a notch or indentation which has been pressed into the pipeline at a predetermined location in the course of fastening the pipeline to the evaporator plate, and into which the clip section of the strut can engage, so that it bears against Slipping is secured in the longitudinal direction of the pipeline.
- the pipe and the sleeve can be easily connected by an adhesive layer to the evaporator plate.
- the tubing and sleeve are enclosed between the evaporator plate on the one hand and a sheet of deformable material such as bitumen, plastic material or aluminum on the other.
- the heat exchanger shown in Fig. 1 in perspective view, provided as an evaporator for a refrigeration device is constructed from a flat base plate 1 made of aluminum sheet on which a refrigerant pipe 2 is arranged in a meandering of a likewise made of aluminum tube.
- 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 further the processability of the layer 3 affecting additives.
- the holding material layer 3 could also consist of a plastic material such as polyethylene, optionally with appropriate additives, or of a strong aluminum foil.

- a provisional mounting 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 facing away from each other 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 because in the space between the two struts 8, the holding material layer 3 can be bonded to the hot-melt adhesive layer 5.

- the length of the sleeve depends in all embodiments according to the length of a temperature sensor to be accommodated in it; this is conventionally about 160 mm.
- the assembly of the heat exchanger is largely the same in the three considered embodiment.
- a film is placed on the assembly of circuit board 1, refrigerant line 2 and sleeve 7, which is provided to form the holding material layer 3.

- hydrostatic pressure can be applied to the film to cause material of the film to enter the gusset 4 between the refrigerant line 2 and the circuit board 1 to penetrate.
- it is sufficient to cut the holding material layer 3 at one end of the sleeve; but it can also be used to press the film, a punch which is shaped so that it brings the film at one end of the sleeve to rupture.
Abstract
Description
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 siehe zum Beispiel Dokument
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..To control the operation of such evaporator temperature controlled, a temperature sensor is generally mounted to the evaporator, which is connected to a thermostat control circuit. This thermostat control circuit switches the chiller on and off so that the temperature detected by the temperature sensor remains in a desired range. The temperature detected by the temperature sensor generally has 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 Wärmetauschem 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
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 such evaporators, it is possible to provide a channel for later accommodating a temperature sensor, e.g. in the form of a sheet metal or plastic pipe, but this can not be done in one operation together with the attachment of the refrigerant pipe, so that a reproducible positioning of such a channel with respect to the refrigerant pipe and thus a uniform control behavior is not readily ensured.
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 curling a peripheral portion of the base plate into a channel for the temperature sensor. In this way, although the position of the temperature sensor is fixed with respect to the base plate, but it is limited to the fact that the temperature sensor can only be positioned at the edge of the base plate, ie in an area that is exposed to relatively strong interfering thermal influences from the outside and whose temperature thus allows only a limited conclusion on 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.Object of the present invention is to provide a heat exchanger for a refrigerator in tube-plate technology, which allows a reproducible positioning of a receiving sleeve for a temperature sensor in a simple manner and without the need for a 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. In this heat exchanger, the sleeve of the surface of the evaporator plate is fixed by at least one attacking the pipe strut, the position of the sleeve is set precisely at a distance from the pipeline, the the length of the strut corresponds. Thus, the delay with which a temperature sensor mounted in the sleeve registers heating or cooling of the refrigerant line is uniform for all mass-produced evaporators of equal length of 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.Assembly of the heat exchanger is simplified if each strut has a clip portion for clamping to the tubing. This allows a quick provisional fixation of the sleeve to the base plate; a definitive fixation, in particular by covering the pipe and the sleeve-bearing side of the Base plate through a cover layer or film, can be done later.
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 integrally formed, preferably from a blank made of a flat material such as in particular metal sheet.
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 separate part of the sleeve and clamped to this. Such a strut may in particular comprise a first clamp portion for clamping to the pipeline and a second clamp portion for clamping to 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 avoid a tilting of the sleeve with respect to the refrigerant line to which it is fixed, the sleeve are preferably associated with 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 may extend in a same direction from the sleeve to engage, in particular, a same rectilinear tubular section extending parallel to the sleeve, but may also extend in opposite directions from the sleeve to engage two different ones Attack on both sides of the sleeve extending portions 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 mounting position of the sleeve in the longitudinal direction of the pipeline, it can be provided that the pipeline carries a marking at the point of application of at least one strut. In particular, such a marking may be a notch or indentation which has been pressed into the pipeline at a predetermined location in the course of fastening the pipeline to the evaporator plate, and into which the clip section of the strut can engage, so that it bears against Slipping is secured in the longitudinal direction of the pipeline.
Die Rohrleitung und die Hülse können auf einfache Weise durch eine Klebeschicht mit der Verdampferplatte verbunden sein.The pipe and the sleeve can be easily connected by an adhesive layer to the evaporator plate.
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.Preferably, the tubing and sleeve are enclosed between the evaporator plate on the one hand and a sheet of deformable material such as bitumen, plastic material or aluminum on the other.

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 in perspective view, provided as an evaporator for a refrigeration device is constructed from a flat base plate 1 made of aluminum sheet on which a
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 Kättemittetteitung 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
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
Ein Kanal 6 zum Aufnehmen eines Temperaturfühlers ist in einem Zwischenraum zwischen zwei parallelen Abschnitten der Kättemittelleitung 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 Kältemitteileitung 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
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 mounting of the
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 set the position of the
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.A second embodiment of the heat exchanger according to the invention will be described with reference to FIGS. 4 to 6, each of Figs. Show 1 to 3 similar views. Again, the
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 weichem die zwei an der Kältemittelleitung 2 angreifenden Streben 8 ausgebildet sind.A variant of this second embodiment is shown in FIG. Unlike the embodiments described above, here the
Die Länge der Hülse richtet sich bei allen Ausgestaltungen nach der Länge eines in ihr unterzubringenden-Temperaturfühlers; diese beträgt herkömmlicherweise ca. 160 mm.The length of the sleeve depends in all embodiments according to the length of a temperature sensor to be accommodated in it; this is conventionally about 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 embodiment. After the sleeve has been clamped to the
