Description

Die Erfindung betrifft einen Verteiler für einen Plattenwärmeübertrager gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a distributor for a plate heat exchanger according to the preamble of patent claim 1.

Ein Verteiler für einen Plattenwärmeübertrager der eingangs genannten Art ist aus dem Dokument DE 20 2008 004 582 U1 bekannt. Dieser Verteiler besteht aus einem Verteilerkörper mit einem von einem Fluid durchströmten Innenraum und mit einem an einer Seite des Verteilerkörpers angeordneten, mit dem Innenraum hydraulisch verbundenen Zufuhranschluss für das Fluid. Darüber hinaus weist dieser Verteiler, und dies gilt auch für den nachfolgend zu erläuternden, erfindungsgemäßen Verteiler, mehrere Abströmöffnungen für das Fluid auf. Ein solcher Verteiler wird, wie im genannten Dokument beschrieben, bei Plattenwärmeübertragern verwendet, um das Fluid möglichst gleichmäßig auf die Kanäle zwischen den Platten verteilen zu können.A distributor for a plate heat exchanger of the type mentioned is from the document DE 20 2008 004 582 U1 known. This distributor consists of a distributor body with an interior through which a fluid flows and with a supply connection for the fluid which is arranged on one side of the distributor body and is hydraulically connected to the interior. In addition, this distributor, and this also applies to the distributor according to the invention to be explained below, has a plurality of outflow openings for the fluid. Such a distributor, as described in the document mentioned, is used in plate heat exchangers in order to be able to distribute the fluid as evenly as possible over the channels between the plates.

Der Erfindung liegt die Aufgabe zugrunde, einen Verteiler der eingangs genannten Art zu verbessern. Insbesondere soll ein noch universeller einsetzbarer Verteiler geschaffen werden. Diese Aufgabe ist mit einem Verteiler für einen Plattenwärmeübertrager der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.The invention has for its object to improve a distributor of the type mentioned. In particular, an even more universally applicable distributor is to be created. This object is achieved with a distributor for a plate heat exchanger of the type mentioned by the features listed in the characterizing part of patent claim 1.

Nach der Erfindung ist vorgesehen, dass im Verteilerkörper ein Zusatzraum für einen Sensor zur Erfassung der Temperatur des Fluids im Innenraum und auf der Seite des Zufuhranschlusses am Verteilerkörper eine Öffnung zur Einbringung des Sensors in den Zusatzraum vorgesehen ist.According to the invention, it is provided that an additional space for a sensor for detecting the temperature of the fluid in the interior and on the side of the supply connection is provided in the distributor body an opening for introducing the sensor into the additional space is provided on the distributor body.

Mit anderen Worten zeichnet sich der erfindungsgemäße Verteiler für einen Plattenwärmeübertrager somit dadurch aus, dass der Zufuhranschluss und der Sensor bzw. der Temperatursensor an der gleichen Seite des Verteilerkörpers angeordnet sind, was insbesondere den Vorteil mit sich bringt, dass der Temperatursensor gemeinsam mit dem Verteiler in den Plattenwärmeübertrager einsetzbar und sodann auf einfache Weise zum Beispiel mit einer Regelungseinrichtung elektrisch verbindbar ausgebildet ist.In other words, the distributor according to the invention for a plate heat exchanger is thus characterized in that the supply connection and the sensor or the temperature sensor are arranged on the same side of the distributor body, which has the particular advantage that the temperature sensor together with the distributor in the plate heat exchanger can be used and is then designed in a simple manner, for example, to be electrically connectable to a control device.

Andere vorteilhafte Weiterbildungen des erfindungsgemäßen Verteilers für einen Plattenwärmeübertrager ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the distributor according to the invention for a plate heat exchanger result from the dependent patent claims.

Der Vollständigkeit halber wird noch auf folgenden, weiter abliegenden Stand der Technik hingewiesen:
Aus den Dokumenten DE 20 2009 017 100 U1 und CN 202675963 U sind Plattenwärmeübertrager bekannt, die zwar einen Temperatursensor, aber keinen erfindungsgemäßen, in den Plattenwärmeübertrager einsetzbaren, mit dem Temperatursensor versehenen Verteiler aufweisen.For the sake of completeness, reference is made to the following, further distant prior art:
From the documents DE 20 2009 017 100 U1 and CN 202675963 U Plate heat exchangers are known which have a temperature sensor, but no distributor according to the invention, which can be used in the plate heat exchanger and is provided with the temperature sensor.

Die ohnehin weiter abliegende Lösung gemäß dem Dokument DE 600 14 890 T2 unterscheidet sich vom Anmeldungsgegenstand mindestens darin, dass bei dieser der erfindungsgemäße Zusatzraum fehlt.The solution that is further away according to the document DE 600 14 890 T2 differs from the subject of the application at least in that it lacks the additional room according to the invention.

Der erfindungsgemäße Verteiler einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels genauer erläutert.The distributor according to the invention, including its advantageous developments according to the dependent claims, is explained in more detail below with the aid of a preferred embodiment.

Der in den Figuren dargestellte Verteiler für einen Plattenwärmeübertrager besteht zunächst in bekannter Weise aus einem Verteilerkörper 1 mit einem von einem Fluid durchströmten Innenraum 1.1 und mit einem an einer Seite des Verteilerkörpers 1 angeordneten, mit dem Innenraum 1.1 hydraulisch verbundenen Zufuhranschluss 1.2 für das Fluid.The distributor for a plate heat exchanger shown in the figures initially consists in a known manner of a distributor body 1 with an interior 1.1 through which a fluid flows and with a supply connection 1.2 for the fluid, which is arranged on one side of the distributor body 1 and is hydraulically connected to the interior 1.1.

Wesentlich für den erfindungsgemäßen Verteiler für einen Plattenwärmeübertrager ist nun, dass im Verteilerkörper 1 ein Zusatzraum 2 für einen Sensor zur Erfassung der Temperatur des Fluids im Innenraum 1.1 und auf der Seite des Zufuhranschlusses 1.2 am Verteilerkörper 1 eine Öffnung 1.3 zur Einbringung des Sensors in den Zusatzraum 2 vorgesehen ist. Dies ist besonders gut in Figur 5 zu erkennen.It is essential for the distributor according to the invention for a plate heat exchanger that an additional space 2 in the distributor body 1 for a sensor for detecting the temperature of the fluid in the interior 1.1 and on the side of the supply connection 1.2 on the distributor body 1 an opening 1.3 for the introduction of the sensor is provided in the additional room 2. This is particularly good in Figure 5 to recognize.

Vorzugsweise ist dabei vorgesehen, dass wahlweise der Verteilerkörper 1 einen runden Querschnitt aufweist und/oder dass vorzugsweise mindestens ein in den Plattenwärmeübertrager einsteckbarer Teil des Verteilerkörpers 1 zylindrisch ausgebildet ist.It is preferably provided that either the distributor body 1 has a round cross section and / or that at least one part of the distributor body 1 that can be inserted into the plate heat exchanger is preferably cylindrical.

Es ist bevorzugt, dass sowohl der Innenraum 1.1 als auch der Zusatzraum 2 rohrförmig ausgebildet und mit ihren Rohrhauptachsen parallel zueinander erstreckt angeordnet sind. Weiterhin weist der Innenraum 1.1 bevorzugterweise einen runden Querschnitt auf. Ebenso weist bevorzugt der Zusatzraum 2 einen runden Querschnitt auf. Dabei sind der Innenraum 1.1 und der Zusatzraum 2 vorzugsweise hydraulisch getrennt voneinander ausgebildet. Weiterhin ist bevorzugt, dass wahlweise ein runder Querschnitt des Innenraums 1.1 und/oder ein runder Querschnitt des Zusatzraums 2 exzentrisch im runden Querschnitt des Verteilerkörpers 1 angeordnet sind/ist.It is preferred that both the interior 1.1 and the additional space 2 are tubular and are arranged with their main tube axes extending parallel to one another. Furthermore, the interior 1.1 preferably has a round cross section. Likewise, the additional space 2 preferably has a round cross section. The interior 1.1 and the additional space 2 are preferably formed hydraulically separate from one another. It is further preferred that a round cross section of the interior 1.1 and / or a round cross section of the additional space 2 are / are arranged eccentrically in the round cross section of the distributor body 1.

Vorzugsweise ist des Weiteren der Verteilerkörper 1 aus einem Grundkörper 1.4 und einem in den Grundkörper 1.4 einsetzbaren Strömungsleitkörper 1.5 gebildet. Es ist außerdem bevorzugt, dass der Verteilerkörper 1, insbesondere wahlweise der Grundkörper 1.4 und/oder der Strömungsleitkörper 1.5, aus einem gut wärmeleitenden, insbesondere metallischen, Material gebildet ist. Zudem ist vorzugsweise der Strömungsleitkörper 1.5 über eine vorzugsweise dem Zufuhranschluss 1.2 am Verteilerkörper 1 gegenüberliegende Einstecköffnung 1.6 am Grundkörper 1.4 in diesen einsetzbar ausgebildet ist (siehe Figuren 3 und 6).Furthermore, the distributor body 1 is preferably formed from a base body 1.4 and a flow guide body 1.5 that can be inserted into the base body 1.4. It is also preferred that the distributor body 1, in particular optionally the base body 1.4 and / or the flow guide body 1.5, is formed from a good heat-conducting, in particular metallic, material. In addition, the flow guide body 1.5 is preferably designed to be insertable in the base body 1.4 via an insertion opening 1.6 on the base body 1.4, preferably opposite the feed connection 1.2 (see Figures 3 and 6 ).

Weiterhin bilden bevorzugterweise der Zufuhranschluss 1.2, der Innenraum 1.1 und die Einstecköffnung 1.6 bei herausgenommenem Strömungsleitkörper 1.5 eine Durchgangsöffnung am Verteilerkörper 1. Ebenso bevorzugt ist zwischen dem Grundkörper 1.4 und dem Strömungsleitkörper 1.6 ein konzentrischer Ringspalt 1.8 vorgesehen. Dabei weist vorzugsweise der Strömungsleitkörper 1.5 eine Eintrittsöffnung 1.5.1, einen Durchgangsraum 1.5.2 und eine Austrittsöffnung 1.5.3 für das Fluid auf, wie unter anderem in Figur 4 dargestellt ist. Zusätzlich ist vorzugsweise der Zufuhranschluss 1.2 in die Eintrittsöffnung 1.5.1 des Strömungsleitkörpers 1.5 ausmündend ausgebildet ist. Es ist außerdem bevorzugt, dass die Austrittsöffnung 1.5.3 eine größere Querschnittsfläche als die Eintrittsöffnung 1.5.1 aufweist.Furthermore, the supply connection 1.2, the interior 1.1 and the insertion opening 1.6, when the flow guide body 1.5 is removed, form a through opening on the distributor body 1. Likewise, a concentric annular gap 1.8 is preferably provided between the base body 1.4 and the flow guide body 1.6. The flow guide body 1.5 preferably has an inlet opening 1.5.1, a passage space 1.5.2 and an outlet opening 1.5.3 for the fluid, as, inter alia, in FIG Figure 4 is shown. In addition, the supply connection 1.2 is preferably designed to open into the inlet opening 1.5.1 of the flow guide body 1.5. It is also preferred that the outlet opening 1.5.3 has a larger cross-sectional area than the inlet opening 1.5.1.

Zudem weist bevorzugt der Verteilerkörper 1 mehrere Abströmöffnungen 1.7 auf (siehe Figuren 1 und 2), wobei dann der Innenraum 1.1 zwischen den Abströmöffnungen 1.7 und dem Zusatzraum 2 angeordnet ist. Bevorzugt ist, dass die Abströmöffnungen 1.7 am Grundkörper 1.4 auf einer der Austrittsöffnung 1.5.3 am Strömungsleitkörper 1.5 gegenüberliegenden Seite des konzentrischen Ringspaltes 1.8 angeordnet sind. Weiterhin sind vorzugsweise die Abströmöffnungen 1.7 längs einer Linie nebeneinander und vorzugsweise mit dieser Linie parallel zum rohrfömrigen Innenraum 1.1 angeordnet. Zuletzt wird noch bevorzugt, dass die Abströmöffungen 1.7 parallel zur Zylinderhauptachse des mindestens teilweise zylindrischen Verteilerkörpers 1 angeordnet sind.In addition, the distributor body 1 preferably has a plurality of outflow openings 1.7 (see Figures 1 and 2 ), in which case the interior 1.1 is arranged between the outflow openings 1.7 and the additional space 2. It is preferred that the outflow openings 1.7 on the base body 1.4 are arranged on a side of the concentric annular gap 1.8 opposite the outlet opening 1.5.3 on the flow guide body 1.5. Furthermore, the outflow openings 1.7 are preferably arranged along a line next to one another and preferably with this line parallel to the tubular interior 1.1. Finally, it is preferred that the outflow openings 1.7 are arranged parallel to the main cylinder axis of the at least partially cylindrical distributor body 1.

Der erfindungsgemäße Verteiler gemäß der in den Figuren gezeigten Ausführungsform funktioniert wie folgt:
Zunächst wird der Strömungsleitkörper 1.5 über die Einstecköffnung 1.6 in den Verteilerkörper 1 eingebracht und zwar so, dass die Austrittsöffnung 1.5.3 zu jener Seite des Grundkörpers 1.4 weist, die der Seite gegenüberliegt, an welcher die Abströmöffnungen 1.7 angeordnet sind. Um die genaue Positionierung zu vereinfachen, können hierfür Leitelemente am Verteilerkörper 1 und am Strömungsleitkörper 1.5 angebracht sein. Nach diesem Schritt wird der Verteilerkörper 1 in einen Fluidanschluss eines Plattenwärmeübertragers eingesetzt und dort befestigt. Idealerweise kommen hierbei die Abströmöffnungen 1.7 in einer Ebene mit den Freiräumen zwischen den Wärmeübertragerplatten zu liegen. Nun wird ein Temperatursensor in den Zusatzraum 2 eingebracht und der Fluidanschluss des Plattenwärmeübertragers mit einer entsprechenden Fluidzuführung, z.B. einer Wasserzuführung, verbunden.The distributor according to the invention according to the embodiment shown in the figures works as follows:
First, the flow guide body 1.5 is introduced into the distributor body 1 via the insertion opening 1.6, specifically in such a way that the outlet opening 1.5.3 points to that side of the base body 1.4 which is opposite the side on which the outflow openings 1.7 are arranged. To simplify the exact positioning, guide elements can be attached to the distributor body 1 and to the flow guide body 1.5. After this step, the distributor body 1 is inserted into a fluid connection of a plate heat exchanger and fastened there. Ideally, the outflow openings 1.7 come to lie in one plane with the free spaces between the heat exchanger plates. A temperature sensor is now introduced into the additional space 2 and the fluid connection of the plate heat exchanger is connected to a corresponding fluid supply, for example a water supply.

Bei laufendem Betrieb des Plattenwärmeübertragers fließt das Fluid durch den Fluidanschluss und durch den Zufuhranschluss 1.2, sowie die Eintrittsöffnung 1.5.1 zunächst in den Strömungsleitkörper 1.5. Von dort aus tritt das Fluid durch die Austrittsöffnung 1.5.3 in den Ringspalt 1.8 aus. Es fließt dann durch den Ringspalt 1.8 und verlässt den Verteilerkörper 1 durch die Abströmöffnungen 1.7. Währenddessen wird die Temperatur des Verteilerkörpers 1 und damit indirekt auch die Temperatur des Fluids durch den Temperatursensor im Zusatzraum 2 gemessen. Durch die mehrfache Umleitung des Fluidstroms innerhalb des Verteilerkörpers 1 werden Turbulenzen im selbigen erzeugt und damit auch die Temperaturverteilung im Verteilerkörper 1 stabilisiert, was der Temperaturmessung zugute kommt. Nach Austritt des Fluids durch die Abströmöffnungen 1.7, verteilt sich dieses zwischen den Platten des Wärmeübertragers.When the plate heat exchanger is in operation, the fluid first flows through the fluid connection and through the supply connection 1.2, and also through the inlet opening 1.5.1, into the flow guide body 1.5. From there, the fluid exits through the outlet opening 1.5.3 into the annular gap 1.8. It then flows through the annular gap 1.8 and leaves the distributor body 1 through the outflow openings 1.7. In the meantime, the temperature of the distributor body 1 and thus indirectly also the temperature of the fluid is measured by the temperature sensor in the additional space 2. Due to the multiple redirection of the fluid flow within the distributor body 1, turbulence is generated in the same and thus also the temperature distribution in the distributor body 1 is stabilized, which benefits the temperature measurement. After the fluid exits through the outflow openings 1.7, it is distributed between the plates of the heat exchanger.

Ist der Temperatursensor defekt oder ist für diesen aus anderen Gründen ein Austausch vorgesehen, so kann dieser einfach, ohne den Plattenwärmeübertrager auseinander zu bauen, aus dem Zusatzraum 2 entfernt und ein neuer dort eingefügt werden. Dies, zusammen mit dem einfachen Einbau des Verteilerkörpers 1 in einen bestehenden Plattenwärmeübertrager, führt zu einem sehr flexibel einsetzbaren Verteiler.If the temperature sensor is defective or if it is to be replaced for other reasons, it can be easily removed from the additional room 2 without disassembling the plate heat exchanger and a new one inserted there. This, together with the simple installation of the distributor body 1 in an existing plate heat exchanger, leads to a very flexibly usable distributor.
