Messmedium vorhanden ist, das von der Temperatur mindestens einer der Fluide beeinflusst wird und mit einer Steuerung und/oder Regeleinrichtung verbunden ist, wobei der Messraum zum Teil von mindestens einer der Wärmetauscherfluide definiert ist. Dabei wird eine optimale Regelung des Plattenwärmetauschers realisiert. Gemäß des Standes der Technik sind diverse technologische und technische Lösungen gegeben, welche eine Trinkwassererwärmung über einen Wärmetauscher mit Hilfe der Regelung der Vorlauftemperatur ausführen. Dabei ist immer im Wesentlichen der Nachteil gegeben, dass dies eine thermische Lösung, die außerhalb des Plattenwärmeübertragers erfolgt, darstellt und somit eine entsprechende große Trägheit des Kreislaufes vorhanden ist. Es sind zum Beispiel Proportionsregler bekannt, welche über eine Membran, wobei diese mit dem kalten Wasser beaufschlagt wird, und über einen dementsprechenden vorhandenen Stößel eine Öffnung oder Schließung eines Ventilbereiches ausführt. Dabei ist der hohe ökonomische mechanische Aufwand, nicht der direkte Einfluss der Temperatur, sondern nur ein Verhältnis von Kaltwasser zum Heizmedium sowie keine Warmhaltefunktion als Nachteile zu betrachten. Gerade diese Nachteile des gegebenen Standes der Technik setzen das Ziel der erfinderischen Lösung voraus, dass es hier zu einer technischen Ausführung kommen sollte, welche mit geringem technischem Aufwand den wesentlichen Nachteil des Standes der Technik beseitigt .Measuring medium is present, which is influenced by the temperature of at least one of the fluids and is connected to a control and / or regulating device, wherein the measuring space is defined in part by at least one of the heat exchange fluids. In this case, an optimal control of the plate heat exchanger is realized. According to the prior art, various technological and technical solutions are given, which perform a drinking water heating via a heat exchanger by means of the control of the flow temperature. There is always essentially the disadvantage that this is a thermal solution that takes place outside of the plate heat exchanger, and thus a corresponding large inertia of the circuit is present. For example, proportional regulators are known, which carry out an opening or closing of a valve area via a membrane, which is acted upon by the cold water, and via a corresponding plunger present therewith. Here, the high economic mechanical effort, not the direct influence of temperature, but only a ratio of cold water to the heating medium and no holding function to be regarded as disadvantages. It is precisely these disadvantages of the prior art that presuppose the aim of the inventive solution that a technical design should be achieved here which eliminates the essential disadvantage of the prior art with little technical effort.
Des Weiteren ist eine technische Lösung DE 102 59 462 Al „Vorgefertigtes Wärmeübergabemittel" bekannt, wo insbesondere an einem Wärmetauscher zwei entsprechende Kammern angeordnet sind, wobei in diesen Kammern vorhandene Temperaturmessfühler eingearbeitet sind, welche zur Regelung und Steuerung des Wärmetauschers und eines Rück- oder Vorlaufes dienlich sind. Nachteil dieser Erfindung ist der hohe ökonomische Aufwand zur Anordnung der zusätzlichen Kammern. Außerdem ist hierbei nachteilig, dass in den Kammern Messfühler angeordnet sind, die wieder eine physikalische Trägheit hervorrufen.Furthermore, a technical solution DE 102 59 462 A1 "prefabricated heat transfer means" is known, where in particular two chambers are arranged on a heat exchanger, wherein existing temperature sensors are incorporated in these chambers, which for controlling and controlling the heat exchanger and a return or flow are helpful. Disadvantage of this invention is the high cost of the arrangement of the additional chambers. In addition, this is disadvantageous in that sensors are arranged in the chambers, which again cause a physical inertia.
Die EP-B-608195 offenbart einen Plattenwärmetauscher mit einer Sensorvorrichtung, der einen Temperatursensor mit einer länglichen Form umfasst. Der Temperatursensor erstreckt sich in einem der Durchgangslochkanäle des Plattenwärmetauschers, der mit einigen der Wärmeübertragungsdurchgänge des Plattenstapels in Verbindung steht. Der Temperatursensor ist über ein so genanntes Kapillarrohr verbunden, das ein Ventil zum Steuern einer Strömung z. B. von Fernwärmewasser durch den Plattenwärmetauscher aufweist.EP-B-608195 discloses a plate heat exchanger having a sensor device comprising a temperature sensor with an elongate shape. The temperature sensor extends in one of the through-hole channels of the plate heat exchanger, which communicates with some of the heat transfer passages of the plate stack. The temperature sensor is connected via a so-called capillary tube, which has a valve for controlling a flow z. B. has district heating water through the plate heat exchanger.
Die WO 97/00415 offenbart einen Plattenwärmetauscher, der als Ölkühler verwendet wird. Der Plattenwärmetauscher umfasst ein Ventil, das von einem Sensor anderen Typs gesteuert wird, nämlich von einer temperaturempfindlichen Feder, die in einem Gehäuse an einem Durchgangslochkanal des Plattenwärmetauschers befestigt ist. Das Ventil öffnet und schließt einen Nebenkanal im Plattenwärmetauscher .WO 97/00415 discloses a plate heat exchanger used as an oil cooler. The plate heat exchanger comprises a valve which is controlled by a sensor of a different type, namely a temperature-sensitive spring, which is fixed in a housing to a through-hole channel of the plate heat exchanger. The valve opens and closes a secondary channel in the plate heat exchanger.
Die DK-U-9600205 offenbart einen Plattenwärmetauscher, der mit einem Raum versehen ist, der sich an der Außenseite desDK-U-9600205 discloses a plate heat exchanger provided with a space located on the outside of the
Plattenwärmetauschers befindet und sich an einer Außenfläche des Plattenwärmetauschers erstreckt. Im Raum ist ein länglicher Temperatursensor vorgesehen. Der Raum ist mit Durchgängen für eines der Fluide im Plattenwärmetauscher verbunden. Der Raum ist in der Nähe einer Einlass- oder Auslassöffnung des Plattenwärmetauschers vorgesehen. Der Temperatursensor ist so angeordnet, dass er mit der Ausrüstung zum Steuern einer Strömung eines der Fluide durch den Plattenwärmetauscher zusammen arbeitet.Plate heat exchanger is located and connected to a Exterior surface of the plate heat exchanger extends. In the room an elongated temperature sensor is provided. The space is connected to passages for one of the fluids in the plate heat exchanger. The space is provided near an inlet or outlet port of the plate heat exchanger. The temperature sensor is arranged to cooperate with the equipment to control a flow of one of the fluids through the plate heat exchanger.
Jedes dieser Dokumente schlägt somit vor, einen separaten Sensor außerhalb des Plattenwärmetauschers oder in irgendeinem der Durchgangslochkanäle des Plattenwärmetauschers vorzusehen. Das Vorsehen eines solchen separaten Sensors ist unter dem Gesichtspunkt der Herstellung schwierig. Weiterhin führt ein Sensor in irgendeinem der Durchgangslochkanäle zu einem vergrößerten Strömungswiderstand, nicht nur aufgrund des Sensors selbst, sondern auch aufgrund der Komponenten, die zum Befestigen des Sensors im Durchgangslochkanal benötigt werden. Die bekannten Anordnungen haben außerdem den weiteren Nachteil, dass die Zeitkonstante lang ist, das heißt, es vergeht eine relativ lange Zeit, bevor eine Temperaturänderung eines oder beider Fluide zu einem hinreichenden Einfluss auf dieses Medium und somit z. B. zu einer gewünschten Änderung der Ventilposition führt.Each of these documents thus proposes to provide a separate sensor outside the plate heat exchanger or in any of the through-hole channels of the plate heat exchanger. The provision of such a separate sensor is difficult from the viewpoint of manufacture. Furthermore, a sensor in any one of the through-hole channels results in increased flow resistance, not only because of the sensor itself, but also because of the components needed to mount the sensor in the through-hole channel. The known arrangements also have the further disadvantage that the time constant is long, that is, it takes a relatively long time before a temperature change of one or both fluids to a sufficient influence on this medium and thus z. B. leads to a desired change in the valve position.
Des Weiteren ist bekannt eine EP 1 362 214, wobei ein Plattenwärmetauscher ausgeführt ist, welcher einen geschlossen Raum für ein Messmedium aufweist. Der Nachteil dieser technischen Lösung besteht darin, dass zusätzlich zu den vorhandenen Wärmeübertragungsplatten eine extra räumliche geschlossene Platte für die Beinhaltung des Mediums integriert werden muss, was einen erheblichen technischen Aufwand darstellt.Furthermore, EP 1 362 214 is known, wherein a plate heat exchanger is designed, which has a has closed space for a measuring medium. The disadvantage of this technical solution is that in addition to the existing heat transfer plates an extra space closed plate for the containment of the medium must be integrated, which represents a considerable technical effort.
Aufgabe der Erfindung ist es, einen Plattenwärmetauscher zu finden, welcher die Nachteile des Standes der Technik beseitigt und keinen zusätzlichen geschlossenen Messraum für ein Messmedium als Zubau für den Plattenwärmetauscher notwendig macht.The object of the invention is to find a plate heat exchanger, which eliminates the disadvantages of the prior art and makes no additional closed measuring space for a measuring medium as an addition to the plate heat exchanger necessary.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass ein Plattenwärmetauscher gemäß dem Hauptanspruch 1 und seinen Unteransprüchen ausgeführt wird.According to the invention the object is achieved in that a plate heat exchanger is carried out according to the main claim 1 and its dependent claims.
Dabei ist ein Plattenwärmetauscher bekannter Bauart gegeben, wobei ein Stapel von Wärmeübertragungsplatten mit den Durchgängen für das Wärmetauscherfluid ausgebildet ist. Die Wärmeübertragungsplatten des Plattenwärmetauschers werden durch Begrenzungsplatten geschlossen.In this case, a plate heat exchanger of known type is given, wherein a stack of heat transfer plates is formed with the passages for the heat exchange fluid. The heat transfer plates of the plate heat exchanger are closed by boundary plates.
In dem Plattenwärmetauscher mit einem Stapel von Wärmeübertragungsplatten und einseitig verbundener Begrenzungsplatte befindet sich ein Messraum zwischen einer äußeren, der Begrenzungsplatte zugeordneten Wärmeübertragungsplatte des Stapels, wobei die Begrenzungsplatte eine mit dem Messraum in Verbindung stehende Öffnung aufweist, über welche der Messraum mit dem Messmedium an eine Sensoreinrichtung koppelbar ist, mit der physikalische Änderungen in dem Messraum erfasst werden.In the plate heat exchanger with a stack of heat transfer plates and limiting plate connected on one side there is a measuring space between an outer heat transfer plate of the stack associated with the limiting plate, the limiting plate communicating with the measuring space has stationary opening, via which the measuring space with the measuring medium can be coupled to a sensor device, are detected with the physical changes in the measuring space.
Dabei werden insbesondere Messmedien verwendet, welche auf eine Temperaturänderung eines Wärmetauscherfluides reagieren und somit ein entsprechendes Stellsignal an eine Sensoreinrichtung weiterleiten. Hierbei wird insbesondere daran gedacht, dass Messmedien beinhaltet sind, welche eine entsprechende Druckänderung durch Temperaturänderung hervorrufen und somit die angeschlossene Sensoreinrichtung beaufschlagen.In particular, measuring media are used which react to a temperature change of a heat exchanger fluid and thus forward a corresponding actuating signal to a sensor device. In this case, it is particularly thought of that measurement media are included, which cause a corresponding pressure change due to temperature change and thus act on the connected sensor device.
Der Messraum zwischen der äußeren Begrenzungsplatte und der zugeordneten Wärmeübertragungsplatte des Stapels ist wenigstens teilweise mittels der äußeren Wärmeübertragungsplatte und der Begrenzungsplatte definiert. Eine Öffnung, welche in Verbindung mit dem Messraum besteht, ist als eine Durchflussöffnung ausgeführt, durch welche hindurch das Messmedium an die Sensoreinrichtung gelangen kann, des Weiteren ist der Messraum in Verbindung mit der Öffnung mit einem Kapillarkanal gekoppelt. Die Öffnung ist so definiert, dass eine den Messraum erweiternde Ausnehmung in der Begrenzungsplatte gebildet ist, die wenigstens teilweise mit dem Messmedium gefüllt ist.The measuring space between the outer boundary plate and the associated heat transfer plate of the stack is at least partially defined by means of the outer heat transfer plate and the boundary plate. An opening, which is in communication with the measuring space, is designed as a flow opening, through which the measuring medium can reach the sensor device, furthermore the measuring space is coupled in conjunction with the opening with a capillary channel. The opening is defined such that a recess widening the measuring space is formed in the limiting plate, which is at least partially filled with the measuring medium.
Wesentlich ist dabei, dass die Größe der erweiternden Ausnehmung der Öffnung entscheidend ist, damit ein bestmöglicher Temperatureinfluss des Wärmetauscherfluides auf das Messmedium, welches in der Öffnung in Form der erweiternden Ausnehmung gegeben ist, gewährleistet wird. Hierzu sind verschiedene erweiternde Ausnehmungen denkbar, welche alle bestehenden Flächenformen aufweisen können.It is essential that the size of the widening recess of the opening is crucial, so that the best possible temperature influence of the Heat exchange fluids to the measuring medium, which is given in the opening in the form of the widening recess, is ensured. For this purpose, various expanding recesses are conceivable, which may have all existing surface shapes.
Die Öffnung als eine den Messraum erweiternde Ausnehmung ist notwendig, um somit einen optimalen Übergang der Temperaturerfassung des Wärmetauscherfluides über das Messmedium hin zur Sensoreinrichtung über den Kapillarkanal zu realisieren. Die Öffnung ist vorteilhafterweise zwischen den Anschlüssen für die Wärmetauscherfluide in der Begrenzungsplatte angeordnet.The opening as a recess widening the measuring space is necessary in order thus to realize an optimum transition of the temperature detection of the heat exchanger fluid via the measuring medium to the sensor device via the capillary channel. The opening is advantageously arranged between the connections for the heat exchanger fluids in the boundary plate.
Des Weiteren sollte die Öffnung in Verbindung mit dem Messraum in ihrer flächenmäßigen Form eine größere Längsausdehnung als Querausdehnung besitzen. Dazu ist es vorteilhaft, die Öffnung in Form eines Schlitzes auszuführen. Somit ist ein wesentlicher Schwerpunkt dahingehend realisiert, dass die erweiternde Ausnehmung der Öffnung in Verbindung mit dem Messraum eine größere Längsausdehnung als Querausdehnung aufweist .Furthermore, the opening in connection with the measuring space should have a greater longitudinal extent than transverse extent in its areal shape. For this purpose, it is advantageous to carry out the opening in the form of a slot. Thus, a significant focus is realized in that the widening recess of the opening in connection with the measuring space has a greater longitudinal extent than transverse extent.
Die Öffnung in Form eines Schlitzes ist wenigstens über ein Drittel der Länge der Begrenzungsplatte erstreckt. Der Schlitz als Form der erweiternden Ausnehmung der Öffnung ist so ausgeführt, dass in Blickrichtung auf die Begrenzungsplatte zwischen dem Schlitz und den Plattenkanälen ein spitzer Winkel gebildet ist. Es ist weiterhin denkbar, dass die Öffnung in Form eines Schlitzes oder einer anderen flächenmäßigen erweiternden Ausnehmung an beliebiger Stelle der Begrenzungsplatte vorhanden ist.The opening in the form of a slot is at least over one third of the length of the boundary plate. The slot as a shape of the widening recess of the opening is designed so that an acute angle is formed in the direction of the boundary plate between the slot and the plate channels. It is also conceivable that the opening in the form of a slot or other planar widening recess at any point of the boundary plate is present.
Des Weiteren ist die Erfindung so ausgeführt, dass die Öffnung auf der äußeren Wärmeübertragungsplatte mittels Oberflächenstrukturierung gebildeten Plattenkanäle gegenüber liegend angeordnet ist, wobei die Anordnung der Öffnung so gestaltet ist, dass sie sich gegenüber liegend des Plattenkanalbereiches befindet, in welchem die Plattenkanäle zusammenlaufen. Wichtig ist dabei, dass die Öffnung sich zumindest abschnittsweise im Wesentlichen quer zu den Plattenkanälen erstreckt.Furthermore, the invention is embodied such that the opening on the outer heat transfer plate is arranged opposite to the plate channels formed by surface structuring, wherein the arrangement of the opening is designed so that it is opposite to the plate channel region in which the plate channels converge. It is important that the opening extends at least partially substantially transversely to the plate channels.
Der Anschluss des Kapillarkanals mit einem jeweiligen Zugang zur Öffnung des Messraumes sollte so ausgeführt werden, dass dieser im Plattenkanalbereich gegenüber liegend ausgerichtet ist. Zu der Öffnung ist eine auf der Begrenzungsplatte außenseitig angeordnete Abdeckplatte zugeordnet. Die Abdeckplatte dient dazu, dass sie die Öffnung als erweiternde Ausnehmung des Messraumes zwischen der Begrenzungsplatte und der zugeordneten Wärmeübertragungsplatte abschließt und dabei den Zugang für den Kapillarkanal hin zur Sensoreinrichtung gewährleistet.The connection of the capillary channel with a respective access to the opening of the measuring chamber should be carried out so that it is aligned opposite in the plate channel area. To the opening on the limiting plate on the outside arranged cover plate is assigned. The cover plate serves to close the opening as a widening recess of the measuring space between the boundary plate and the associated heat transfer plate, thereby ensuring access for the capillary channel to the sensor device.
Anhand eines Ausführungsbeispiels und den allgemeinen Erläuterungen wird ein Plattenwärmetauscher beschrieben . Dabei zeigen:Reference to an embodiment and the general explanations, a plate heat exchanger will be described. Showing:
Figur 1 BegrenzungsplatteFigure 1 boundary plate
Figur 2 Begrenzungsplatte mit Ausschnitt Figur 3 Seitenansicht Plattenwärmetauscher.Figure 2 boundary plate with cutout Figure 3 Side view plate heat exchanger.
Aus den Figuren 1 und 2 ist eine Begrenzungsplatte 1 eines vorgegebenen Plattenwärmetauschers 9 mit einem integrierten Plattenstapel aus Wärmeübertragungsplatten bekannter Bauart gegeben.From Figures 1 and 2, a limiting plate 1 of a given plate heat exchanger 9 is provided with an integrated plate stack of heat transfer plates of known design.
Dabei sind die Wärmeübertragungsplatten mit entsprechenden Plattenkanälen 4 so ausgeführt, dass diese Plattenkanäle 4 in Wellenform angeordnet sind und zusätzlich eine Spitze Plattenkanäle 11 aufweisen. Diese einzelnen Wärmeübertragungsplatten sind als Plattenstapel übereinander angeordnet.In this case, the heat transfer plates are designed with corresponding plate channels 4 so that these plate channels 4 are arranged in waveform and additionally have a tip plate channels 11. These individual heat transfer plates are arranged one above the other as a stack of plates.
Der Plattenwärmetauscher 9 ist mit einer oberhalb und unterhalb ausgeführten Begrenzungsplatte 1 kontruiert. Dabei sind die Begrenzungsplatten 1 jeweils mit der oberhalb und unterhalb ausgeführtenThe plate heat exchanger 9 is kontruiert with a running above and below boundary plate 1. The boundary plates 1 are each executed with the above and below
Wärmeübertragungsplatte fest verlötet. Somit ist eine direkte Verbindung der Begrenzungsplatte 1 mit der jeweiligen Wärmeübertragungsplatte vorhanden. In denSoldered heat transfer plate firmly. Thus, there is a direct connection of the restriction plate 1 with the respective heat transfer plate. In the
Wärmeübertragungsplatten sind die entsprechendenHeat transfer plates are the corresponding ones
Wärmetauscherfluide als Austauschmedium gegeben.Heat exchange fluids are given as exchange medium.
Der Plattenwärmetauscher 9, wie diesseitig beschrieben, wurde erfindungsgemäß so verändert, dass ein Messraum zwischen der äußeren Begrenzungsplatte 1 und der zugeordneten Wärmeübertragungsplatte des Stapels vorhanden ist und die Begrenzungsplatte 1 eine mit dem Messraum in Verbindung stehenden Öffnung 3 aufweist. Diese Öffnung 3 als eine den Messraum erweiternde Ausnehmung in der Begrenzungsplatte 1 ist als Schlitz 12 realisiert.The plate heat exchanger 9, as described on the side, has been changed according to the invention so that a measuring space between the outer boundary plate 1 and the associated heat transfer plate of Stack is present and the boundary plate 1 has an opening 3 in communication with the measuring space. This opening 3 as a measuring space widening recess in the boundary plate 1 is realized as a slot 12.
In dem Messraum und der erweiternden Ausnehmung Öffnung 3 ist ein Messmedium 10 an eine Sensoreinrichtung gekoppelt, womit die physikalischen Änderungen in dem Messraum erfasst werden.In the measuring space and the widening recess opening 3, a measuring medium 10 is coupled to a sensor device, whereby the physical changes in the measuring space are detected.
Wesentlich ist dabei, dass der Messraum wenigstens teilweise mittels der äußeren Wärmeübertragungsplatte und der Begrenzungsplatte 1 definiert ist. Der Messraum und die daraus definierte in Verbindung stehende Öffnung 3 in Form eines Schlitzes 12 ist über einen Zugang 6 mit einem Kapillarkanal 5 verbunden. Die Öffnung 3 des Messraumes ist als eine Durchflussöffnung ausgeführt, wodurch das Messmedium 10 zu der Sensoreinrichtung gelangen kann.It is essential that the measuring space is at least partially defined by means of the outer heat transfer plate and the boundary plate 1. The measuring space and the associated opening 3 in the form of a slot 12 defined therefrom are connected via an access 6 to a capillary channel 5. The opening 3 of the measuring chamber is designed as a flow opening, whereby the measuring medium 10 can reach the sensor device.
In dem entsprechenden Ausführungsbeispiel gemäß den Figuren 1 bis 3 ist die Öffnung 3 als eine den Messraum erweiternde Ausnehmung in der Begrenzungsplatte 1 so ausgeführt, dass sie wenigstens teilweise mit dem Messmedium 10 gefüllt ist. Dabei ist die Öffnung 3 als ein Schlitz 12 ausgeführt. Der Schlitz 12 ist so gegeben, dass dieser eine größere Längsausdehnung als Querausdehnung aufweist. Das Ausführungsbeispiel zeigt nun einen Schlitz 12 zwischen den Anschlüssen 2 und 2Λ, welcher mittig angeordnet ist. Die Länge des Schlitzes 12 ist so ausgeführt, dass er zirka ein Drittel der Gesamtlänge des Plattenwärmetauschers 9 umfasst. In möglichen anderen Anwendungsfällen ist die Anordnung des Schlitzes 12 auch über die gesamte Länge bzw. an anderen Stellen mittig oder auf der anderen Seite der Begrenzungsplatte 1 denkbar. Vorteilhafterweise wird der Schlitz 12 am Ausgang des Plattenwärmetauschers 9 aus messtechnischer Sicht angeordnet. Der Schlitz 12 in der Begrenzungsplatte 1 weist ebenfalls einen Zugang 6 für den Anschluss eines Kapillarkanals 5 auf .In the corresponding exemplary embodiment according to FIGS. 1 to 3, the opening 3 is designed as a recess widening the measuring space in the limiting plate 1 in such a way that it is at least partially filled with the measuring medium 10. In this case, the opening 3 is designed as a slot 12. The slot 12 is given so that it has a greater longitudinal extent than transverse extent. The embodiment now shows a slot 12 between the terminals 2 and 2 Λ , which is arranged centrally. The length of the slot 12 is designed so that it comprises about one third of the total length of the plate heat exchanger 9. In other possible applications, the arrangement of the slot 12 is also conceivable over the entire length or at other locations in the middle or on the other side of the boundary plate 1. Advantageously, the slot 12 is arranged at the outlet of the plate heat exchanger 9 from a metrological point of view. The slot 12 in the boundary plate 1 also has an access 6 for the connection of a capillary channel 5.
Da die Plattenkanäle 4 der Wärmeübertragungsplatte eine Wellenform aufweisen, die nur mit der oberen Welle des Plattenkanals 4 mit der Begrenzungsplatte 1 verlötet sind, entsteht über dem Schlitz 12 in der Ebene des Schlitzes 12 der Öffnung 3 ein Hohlraum und eine Verbindung mit den darunter liegenden Plattenkanälen 4 der Wärmeübertragungsplatte auf Grundlage des Hohlraumes des Schlitzes 12 und der Wellenform des Plattenkanals 4. In diesem gegebenen Hohlraum wird ein Messmedium 10 in Form einer Kapillarflüssigkeit eingegeben. Das Messmedium 10 kann auch mit anderen temperaturabhängigen Medien beaufschlagt werden. Durch den direkten Kontakt des Messmediums 10 in dem Hohlraum zwischen den Plattenkanälen 4 der Wärmeübertragungsplatte und dem Schlitz 12 ist über den Zugang 6 und im Anschluss eines Kapillarkanals 5 ein direkter Abgang bei Veränderung des Messmediums 10 gegeben.Since the plate channels 4 of the heat transfer plate have a waveform that are soldered to the limiting plate 1 only with the upper shaft of the plate channel 4, a cavity is formed above the slot 12 in the plane of the slot 12 of the opening 3 and a connection with the underlying plate channels 4 of the heat transfer plate based on the cavity of the slot 12 and the waveform of the plate channel 4. In this given cavity, a measuring medium 10 is input in the form of a capillary. The measuring medium 10 can also be acted upon by other temperature-dependent media. Due to the direct contact of the measuring medium 10 in the cavity between the plate channels 4 of the heat transfer plate and the slot 12 is on the access 6 and in connection a capillary channel 5 a direct departure given change in the measuring medium 10.
Dabei ist die Öffnung 3 als Schlitz 12 auf der äußeren Wärmeübertragungsplatte mittelsIn this case, the opening 3 as a slot 12 on the outer heat transfer plate by means
Oberflächenstrukturierung gebildeten Plattenkanälen gegenüber liegend angeordnet, in welcher dieSurface structuring formed formed plate channels opposite, in which the
Plattenkanäle 4 zusammenlaufen. Mit einem Blickwinkel auf die Begrenzungsplatte 1 zwischen dem Schlitz 12 und den Plattenkanälen 4 entsteht ein spitzer Winkel.Plate channels 4 converge. With a view of the boundary plate 1 between the slot 12 and the plate channels 4 creates an acute angle.
Der Schlitz 12 der Begrenzungsplatte 1 ist auf derThe slot 12 of the limiting plate 1 is on the
Oberfläche verschlossen.Surface closed.
Gemäß den Figuren 2 und 3 wird eine gesonderte Abdeckplatte 7 ausgeführt. Diese Abdeckplatte 7 ist über die Größe des Schlitzes 12 luft- und flüssigkeitsdicht auf die Begrenzungsplatte 1 zum Verschluss des Schlitzes 12 aufgebracht.According to Figures 2 and 3, a separate cover plate 7 is executed. This cover plate 7 is air-tight and liquid-tight over the size of the slot 12 applied to the limiting plate 1 for closing the slot 12.
Der Zugang 6 für den Kapillarkanal 5 wird durch die Abdeckplatte 7 ausgeführt, um somit die Durchflussöffnung für das Messmedium 10 von dem Messraum hin zur Sensoreinrichtung zu gewährleisten.The access 6 for the capillary channel 5 is performed by the cover plate 7, thus ensuring the flow opening for the measuring medium 10 from the measuring space to the sensor device.
Aus der Figur 3 heraus ist diese Anordnung der Abdeckplatte 7 dahingehend ersichtlich, dass der Schlitz 12 in der Begrenzungsplatte 1 mit dem beinhalteten Messmedium 10 in dem Hohlraum zwischen den Plattenkanälen 4 und dem Schlitz 12 ausgeführt ist. Dabei ist die Abdeckplatte 7 in ihrer Größe länger als der vorhandene Schlitz 12 in der Begrenzungsplatte 1. Auf Grundlage dieser erfindungsgemäßen Anordnung des beschriebenen Ausführungsbeispiels aus den Figuren 1,From FIG. 3, this arrangement of the cover plate 7 can be seen in that the slot 12 in the boundary plate 1 with the contained measuring medium 10 is embodied in the cavity between the plate channels 4 and the slot 12. In this case, the cover plate 7 is longer in size than the existing slot 12 in the boundary plate. 1 Based on this inventive arrangement of the described embodiment of Figures 1,
2 und 3 ist der Vorteil der erfinderischen Lösung dadurch gegeben, dass kein gesonderter Messraum als Einbau bzw. Anbau für die Beaufschlagung eines Messmediums 10 benötigt wird. Dadurch wird ein wesentlicher Nachteil des Standes der Technik beseitigt .2 and 3, the advantage of the inventive solution is given by the fact that no separate measuring space is required as installation or cultivation for the admission of a measuring medium 10. This eliminates a major drawback of the prior art.
Erfindungswesentlich ist bei der technischen Lösung, dass ein gegebener Plattenwärmetauscher 9 bekannter Bauart so verändert wird, dass im Rahmen seiner Bauweise ein Messraum in Verbindung mit einer ÖffnungEssential to the invention is in the technical solution that a given plate heat exchanger 9 of known type is changed so that in its construction a measuring space in conjunction with an opening
3 in Form eines Schlitzes 12 in der vorhandenen Begrenzungsplatte 1 geschaffen wird, worin ein3 is provided in the form of a slot 12 in the existing boundary plate 1, wherein a
Messmedium 10 integriert ist. Über den Zugang 6 und den Kapillarkanal 5 können nun steuerungs- und regelungstechnische Einrichtungen für die weitere Anwendung des Plattenwärmetauschers 9 angeschlossen werden. Wie schon beschrieben, muss also kein zusätzlicher Raum in Form einer Platte oder kein Plattenanbau als Messraum für das Messmedium 10 integriert werden, was einen hohen technischen Aufwand darstellt und den Nachteil der bekannten technischen Lösung darstellt.Measuring medium 10 is integrated. Via the access 6 and the capillary channel 5 control and control equipment for the further application of the plate heat exchanger 9 can now be connected. As already described, therefore, no additional space in the form of a plate or plate mounting as a measuring space for the measuring medium 10 must be integrated, which is a high technical effort and represents the disadvantage of the known technical solution.
Aus messtechnischer Sicht ist ein weiterer Vorteil dahingehend gegeben, dass ein direkter Kontakt des Messmediums 10 in den Messraum in Verbindung mit der Öffnung 3 über die Wärmeübertragungsplatte des Plattenwärmetauschers 9 mit beinhaltetem Wärmetauscherfluid gegeben ist. Aus diesem direkten Kontakt der Wärmeübertragungsplatte des Plattenwärmetauschers 9 und dem Messraum in Verbindung mit der Öffnung 3 und beinhaltetem Messmedium 10 sind exakte steuerungs- und regelungstechnische Ergebnisse möglich. From a metrological point of view, a further advantage is given to the effect that a direct contact of the measuring medium 10 is given in the measuring space in connection with the opening 3 via the heat transfer plate of the plate heat exchanger 9 with included heat exchange fluid. For this direct Contact the heat transfer plate of the plate heat exchanger 9 and the measuring chamber in conjunction with the opening 3 and measuring medium 10 contained precise control and control technical results are possible.
