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 arranged on one side of the distributor body and 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 is, as described in said document, used in plate heat exchangers to distribute the fluid as evenly as possible on the channels between the plates can.

Der Erfindung liegt die Aufgabe zugrunde, einen Verteiler der eingangs genannten Art zu verbessern. Insbesondere soll ein noch universeller einsetzbarer Verteiler geschaffen werden.The invention has for its object to improve a distributor of the type mentioned. In particular, a more universally applicable distributor is to be created.

Diese Aufgabe ist mit einem Verteiler für einen Plattenwärmeübertrager der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.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 in the distributor body an additional space for a sensor for detecting the temperature of the fluid in the interior and on the side of the supply port on the distributor body an opening for introduction of the sensor is provided in the additional space.

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 for a plate heat exchanger according to the invention thus characterized by the fact that the supply port and the sensor or the temperature sensor are arranged on the same side of the distributor body, which in particular brings with it the advantage that the temperature sensor together with the distributor in the plate heat exchanger can be used and then formed in a simple manner, for example, with a control device electrically connected.

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 resulting from the dependent 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 prior art:
From the documents DE 20 2009 017 100 U1 and CN 202675963 U plate heat exchangers are known, although having a temperature sensor, but not according to the invention, can be used in the plate heat exchanger, provided with the temperature sensor distributor.

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 already more remote solution according to the document DE 600 14 890 T2 differs from the subject of the application at least that is missing in this invention the additional space.

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 will be explained in more detail with reference to the drawing 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 a flowed through by a fluid interior 1.1 and with a arranged on one side of the manifold body 1, with the interior 1.1 hydraulically connected supply port 1.2 for the fluid.

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 each other. Furthermore, the interior 1.1 preferably has a round cross-section. Likewise, the additional space 2 preferably has a round cross section. In this case, the interior 1.1 and the additional space 2 are preferably formed hydraulically separated from each other. Furthermore, it is preferred that either a round cross section of the interior 1.1 and / or a round cross section of the additional space 2 are arranged eccentrically in the round cross section of the distributor body 1 / is.

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 which 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 of a good heat-conducting, in particular metallic, material. In addition, the flow guide body 1.5 is preferably formed via a preferably the supply port 1.2 on the manifold body 1 opposite insertion opening 1.6 on the base body 1.4 in this insertable (see FIGS. 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 port 1.2, the interior 1.1 and the insertion opening 1.6 preferably form a passage opening on the distributor body 1 with the flow guide body 1 taken out. It is likewise preferred to provide a concentric annular gap 1.8 between the base body 1.4 and the flow guide body 1.6. In this case, 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, such as, inter alia FIG. 4 is shown. In addition, preferably, the supply port 1.2 is formed ausmündend in the inlet opening 1.5.1 of the flow guide 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 FIG 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 are arranged 1.7 on the base body 1.4 on one of the outlet opening 1.5.3 on the flow guide 1.5 opposite side of the concentric annular gap 1.8. Furthermore, the outflow openings are preferably 1.7 along a line next to each other and preferably arranged with this line parallel to the pipe-shaped interior 1.1. Finally, it is further preferred that the outflow openings 1.7 are arranged parallel to the cylinder main 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 1.5 is introduced via the insertion opening 1.6 in the distributor body 1 in such a way that the outlet opening 1.5.3 to that side of the base body 1.4 has, which is opposite to the side on which the outflow openings are arranged 1.7. In order to simplify the exact positioning, guide elements can be attached to the distributor body 1 and to the flow guide body 1.5 for this purpose. 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 in this case come to rest in a plane with the free spaces between the heat exchanger plates. Now, a temperature sensor is introduced into the additional space 2 and the fluid connection of the plate heat exchanger connected to a corresponding fluid supply, such as 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.During operation of the Plattenwärmeübertragers the fluid flows through the fluid port and through the supply port 1.2, and the inlet opening 1.5.1 first in the flow guide 1.5. From there, the fluid exits through the outlet opening 1.5.3 in 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. Meanwhile, the temperature of the distributor body 1 and thus indirectly the temperature of the fluid is measured by the temperature sensor in the additional space 2. Due to the multiple diversion of the fluid flow within the distributor body 1, turbulences are generated in the same and thus also the temperature distribution in the distributor body 1 stabilized, which benefits the temperature measurement. After the fluid exits through the outflow openings 1.7, this 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 faulty or if replacement is provided for it for other reasons, it can simply be removed from the additional space 2 without having to disassemble the plate heat exchanger, and a new one can be inserted there. This, together with the simple installation of the distributor body 1 in an existing plate heat exchanger, leads to a very flexible distributor.
