Jede Wärmetauscherplatte 2 weist einen umlaufenden Kragen 4 auf, der mit einem Winkel von etwa 75° gegenüber der Ebene der Wärmetauscherplatte 2, entsprechend Fig. 1, nach oben abgewinkelt ist. Jede Wärmetauscherplatte 2 weist vier Durchlaßöffnungen 5 bzw. 5' auf, von denen in dieser Schnittdarstellung jedoch nur zwei erkennbar sind. Die Durchlaßöffnungen 5 bzw. 5' müssen entgegen dem dargestellten Ausführungsbeispiel nicht den gleichen Querschnitt aufweisen. In der Nähe des umlaufenden Kragens 4 sind in jeder Wärmetauscherplatte 2 vier Öffnungen 6 vorgesehen, die jeweils mit einem umlaufenden Kragen 7 versehen sind. Dabei sind im dargestellten Schnitt bei jeder Wärmetauscherplatte 2 nur zwei der Öffnungen 6 sichtbar.In Fig. 1, eight heat exchanger plates are in an exploded view 2 with intervening turbulence inserts 3 or 3 'shown in a sectional view. Each Heat exchanger plate 2 has a circumferential collar 4, which is at an angle of about 75 ° to the plane of the Heat exchanger plate 2, according to Fig. 1, angled upwards is. Each heat exchanger plate 2 has four passage openings 5 or 5 ', of which in this sectional view however only two are recognizable. The passage openings 5 and 5 'must be contrary to the illustrated embodiment do not have the same cross section. Nearby of the circumferential collar 4 are in each heat exchanger plate 2 four openings 6 are provided, each with a circumferential Collar 7 are provided. Here are shown in Cut only two of the openings in each heat exchanger plate 2 6 visible.

Jeweils zwischen zwei Wärmetauscherplatten 2 ist eine Turbulenzeinlage 3 bzw. 3' angeordnet. Jede Turbulenzeinlage weist zu den Durchlaßöffnungen 5 bzw. 5' der Wärmetauscherplatten 2 korrespondierende Öffnungen 8 und 9 auf. In den Öffnungen 9 ist jeweils ein Dichtring 10 eingebracht, dessen Außendurchmesser in etwa dem Innendurchmesser der Öffnung 9 entspricht und dessen Innendurchmesser in etwa dem Innendurchmesser der Öffnung 5 bzw. 5' entspricht. Der Innendurchmesser der Öffnung 8 der Turbulenzeinlage 3 bzw. 3' entspricht etwa dem Innendurchmesser der Öffnung 5 bzw. 5' in der Wärmetauscherplatte 2. In jeder Turbulenzeinlage 3 bzw. 3' sind zwei Öffnungen 8 und zwei Öffnungen 9 mit darin eingebrachtem Dichtring 10 vorgesehen, wobei in der geschnitten Darstellung jeweils nur eine Öffnung 8 und eine Öffnung 9 sowie ein Dichtring 10 sichtbar sind. In entsprechender Weise enthält jede Turbulenzeinlage 3 bzw. 3' vier Öffnungen 11, die den Öffnungen 6 der Wärmetauscherplatten 2 zugeordnet sind und deren Innendurchmesser etwa dem Außendurchmesser am Ansatz des Kragens 7 an der Öffnung 6 entspricht.There is a turbulence insert between each of the two heat exchanger plates 2 3 or 3 'arranged. Every turbulence insert points to the passage openings 5 and 5 'of the heat exchanger plates 2 corresponding openings 8 and 9. In the Openings 9 each have a sealing ring 10 introduced Outer diameter approximately the inner diameter of the opening 9 corresponds and its inner diameter approximately the inner diameter corresponds to the opening 5 or 5 '. The inside diameter the opening 8 of the turbulence insert 3 or 3 ' corresponds approximately to the inside diameter of the opening 5 or 5 ' in the heat exchanger plate 2. In each turbulence insert 3 and 3 'are two openings 8 and two openings 9 with therein introduced sealing ring 10 provided, cut in the Representation of only one opening 8 and one Opening 9 and a sealing ring 10 are visible. In corresponding Each turbulence insert 3 or 3 'contains four Openings 11, the openings 6 of the heat exchanger plates 2nd are assigned and their inner diameter approximately the outer diameter at the neck of the collar 7 corresponds to the opening 6.

Dabei entstehen Kanäle, durch die ein jeweiliges Fluid zum nächsten Zwischenraum gelangen kann. Auf diese Weise befüllen sich die Zwischenräume abwechselnd mit dem Kühlfluid und dem zu kühlenden Fluid, zum Beispiel Öl. Beispielsweise können die Öffnungen 5 und die damit kommunizierenden Zwischenräume dem Kühlmittel zugeordnet sein, wobei die zugehörigen Turbulenzeinlagen 3 und die daran angrenzenden Wärmetauscherplatten 2 mit einer mit a bezeichneten geschweiften Klammer auf der linken Seite der Fig. 1 gekennzeichnet sind. Auf der anderen Seite ist das zu kühlende Fluid den Öffnungen 5' und den damit kommunizierenden Zwischenräumen mit den Turbulenzeinlagen 3' zugeordnet, was durch die mit b bezeichneten geschweiften Klammern auf der rechten Seite in Fig. 1 gekennzeichnet ist. When stacking the heat exchanger plates 2 seal one another the sealing rings 10, the openings 5 and 5 'with respect to one forming between adjacent heat exchanger plates 2 Space and the turbulence insert 3 inserted therein or 3 '. This creates channels through which a respective Fluid can get to the next space. To this The gaps alternately fill with the Cooling fluid and the fluid to be cooled, for example oil. For example can the openings 5 and the communicating with them Spaces can be assigned to the coolant, wherein the associated turbulence inserts 3 and those adjoining them Heat exchanger plates 2 with a curly marked with a Bracket marked on the left side of FIG. 1 are. On the other hand, that's cooling Fluid the openings 5 'and the spaces communicating therewith associated with the turbulence inserts 3 'what by the curly brackets marked b on the right side in Fig. 1 is marked.

Diese oberste Wärmetauscherplatte 2' unterscheidet sich von den übrigen Wärmetauscherplatten 2 durch die Höhe ihres umlaufenden Kragens 4' und durch die Höhen der Kragen 7' an den Öffnungen 6. Dabei sind die Kragen 4' und 7' der obersten Wärmetauscherplatte 2' etwa halb so groß wie die entsprechenden Kragen 4 und 7 einer anderen Wärmetauscherplatte 2, so daß die Kragen 4' und 7' der obersten Wärmetauscherplatte 2' und die Kragen 4 und 7 der daran angrenzenden Wärmetauscherplatte 2 an ihren freien Stirnseiten gemeinsam enden. Die einzelnen Wärmetauscherplatten 2 bzw. 2' sind an ihren sich überlappenden Kragen 4, 4', 7, 7' beispielsweise durch Verlöten dicht miteinander verbunden. Ebenso ist die Anschlußplatte 26 an der obersten Wärmetauscherplatte 2' gegenüber dieser abgedichtet befestigt.2 has a plate heat exchanger 1 stacked and sealed assembled heat exchanger plates 2 additionally a connection plate 26, in the, according to Fig. 2 top, heat exchanger plate 2 'is used and in a manner corresponding to that Turbulence inserts 3 and 3 'has openings 27 which the Openings 6 of the heat exchanger plate 2 are assigned.

Dabei überdecken die Durchlaßkanäle 14 entsprechende Zu- und Abfuhrleitungen 23 für das zweite Fluid (zu kühlendes Öl), wobei die Durchlaßöffnungen 5 der untersten Wärmetauscherplatte 2 die entsprechenden Anschlußöffnungen für die Zu- und Abfuhr des zweiten Fluids bilden. Die Durchlaßkanäle 14 des ersten Fluidkreislaufes werden dabei an den Durchlaßöffnungen 5' in der untersten Wärmetauscherplatte 2 durch entsprechende Dichtmittel gegenüber dem angeschlossenen Körper 20 abgedichtet, insbesondere können an der Anschlußfläche 22 des Körpers Wölbungen in der Art der Wölbungen 13 an der Anschlußplatte 26 vorgesehen sein, um die Positionierung des Plattenwärmetauschers 1 auf dem Körper 20 zu erleichtern.For connecting the plate heat exchanger 1 to another, body 20 shown in part, for example to a The engine block of a motor vehicle is this body 20 with one to the flat underside of the bottom, according to FIG. 2, Heat exchanger plate 2 corresponding, pad 22 provided. The passageways 14 overlap corresponding supply and discharge lines 23 for the second Fluid (oil to be cooled), the passage openings 5 of the lowest heat exchanger plate 2 the corresponding connection openings form for the supply and discharge of the second fluid. The passage channels 14 of the first fluid circuit are thereby at the passage openings 5 'in the lowest heat exchanger plate 2 by appropriate sealant against the connected body 20 sealed, in particular can at the pad 22 of the body bulges in the manner the curvatures 13 can be provided on the connecting plate 26, to position the plate heat exchanger 1 on the To facilitate body 20.

Zur Befestigung des Plattenwärmetauschers 1 am angeschlossenen Körper sind in diesem senkrecht zu den Ebenen der Wärmetauscherplatten 2 verlaufende Durchlässe 15 vorgesehen. Dabei wird jeder Durchlaß 15 aus den sich gegenseitig überlappenden, miteinander verbundenen Kragen 7 bzw. 7' der Öffnungen 6 in den Wärmetauscherplatten 2 bzw. 2' gebildet. Aufgrund ihrer Verbindung untereinander, beispielsweise durch Verlöten, bilden die aneinandergrenzenden Kragen 7 bzw. 7' eine Art Hülse, die in ihrer axialen Richtung auf Druck belastbar ist. Der Innenraum dieser Hülse bildet dabei den Durchlaß 15.To attach the plate heat exchanger 1 to the connected one Bodies in this are perpendicular to the planes of the heat exchanger plates 2 extending passages 15 are provided. Here each passage 15 is made up of the mutually overlapping interconnected collar 7 or 7 'of the openings 6 formed in the heat exchanger plates 2 and 2 '. Because of their connection with each other, for example by Solder, form the adjacent collars 7 and 7 ' a kind of sleeve that can withstand pressure in its axial direction is. The interior of this sleeve forms the Passage 15.

Zum Festlegen des Plattenwärmetauschers 1 am angeschlossenen Körper 20 wird durch den Durchlaß 15 ein Zuganker beispielsweise eine Schraube 16 durchgeführt, die einerseits mit ihrem Kopf 17 auf der Stirnseite der aus den Kragen 7 bzw. 7' gebildeten Hülse aufliegt und andererseits im Körper 20 verankert ist. Im gezeigten Ausführungsbeispiel enden die Stirnseiten der Kragen 7' und 7 der obersten Wärmetauscherplatte 2' bzw. der daran angrenzenden Wärmetauscherplatte 2 gemeinsam und bilden dabei eine als Widerlager dienende Auflage 18, auf der der Schraubenkopf 17 über eine Unterlegscheibe 19 aufliegt und dessen Zugkraft in den Plattenwärmetauscher 1 einleitet. To set the plate heat exchanger 1 on the connected one Body 20 becomes a tie rod through passage 15, for example a screw 16 performed on the one hand with her Head 17 on the end face of the collar 7 or 7 ' formed sleeve rests and on the other hand anchored in the body 20 is. In the embodiment shown, the end End faces of the collar 7 'and 7 of the uppermost heat exchanger plate 2 'or the adjacent heat exchanger plate 2 together and form a support that serves as an abutment 18, on which the screw head 17 via a washer 19 rests and its tensile force in the plate heat exchanger 1 initiates.

In gleicher Weise wie die im Ausführungsbeispiel dargestellte Schraube 16 kann ein vom Körper 20 ausgehender Steckbolzen oder eine Gewindestange als Zuganker dienen, wobei der Plattenwärmetauscher 1 dementsprechend mit Schraubenmuttern am Körper 20 festgelegt wird.In the same way as that shown in the exemplary embodiment Screw 16 can be a socket bolt extending from the body 20 or a threaded rod serve as a tie rod, the Plate heat exchanger 1 accordingly with screw nuts is set on the body 20.

Entsprechend Fig. 2 ist der Plattenwärmetauscher 1 auf der linken Seite beispielhaft am Körper 20 befestigt. In der ebenen Anschlußfläche 22 des Körpers 20 ist eine Zulaufleitung 23 vorgesehen, die mit dem Zulauf des zweiten Fluidkreislaufes des Plattenwärmetauschers 1 kommuniziert, dem die Durchlaßkanäle 14, die Öffnungen 5 und die zugehörigen Zwischenräume zugeordnet sind. Koaxial zur Zufuhrleitung 23 ist eine Ringnut 24 in der Anschlußfläche 22 des Körpers 20 ausgenommen, in die ein Dichtring 21 eingesetzt ist, um den Körper 20 gegenüber dem zweiten Fluidkreislauf des Plattenwärmetauschers 1 abzudichten. In ähnlicher Weise können weitere Dichtringe in der Anschlußfläche 22 des Körpers 20 vorgesehen sein, um die offenen Enden der Durchlaßkanäle 14' des ersten Fluidkreislaufs gegenüber dem Körper 20 abzudichten.2, the plate heat exchanger 1 is on the left side attached to the body 20 as an example. In the flat pad 22 of the body 20 is an inlet line 23 provided with the inflow of the second fluid circuit communicates the plate heat exchanger 1, the the passages 14, the openings 5 and the associated Spaces are assigned. Coaxial with the feed line 23 is an annular groove 24 in the pad 22 of the body 20th except in which a sealing ring 21 is inserted to the Body 20 opposite the second fluid circuit of the plate heat exchanger 1 seal. Similarly, others can Sealing rings are provided in the connection surface 22 of the body 20 be the open ends of the passages 14 ' the first fluid circuit to seal against the body 20.

Die durch den Durchlaß 15 eingeführte, den Plattenwärmetauscher 1 durchdringende Schraube 16 ist im Körper 20 in eine Gewindebohrung 25 eingeschraubt. Vorzugsweise werden zur Verankerung des Plattenwärmetauschers 1 am Körper 20 vier, jeweils im Bereich einer Ecke des Plattenwärmetauschers 1 angeordnete Zuganker 16 verwendet, um eine möglichst gleichmäßige Verteilung der Befestigungskräfte zu erreichen. Selbst beim Auftreten hoher Drücke kann der Plattenwärmetauscher 1 nicht vom angeschlossenen Körper 20 abheben, da die Zuganker 16 aufgrund ihrer hohen Zugfestigkeit auftretenden Volumenausdehnungen des Plattenwärmetauschers 1 von der dem Körper 20 abgewandten Oberseite des Plattenwärmetauschers 1 entgegenwirken. Eine Volumenausdehnung des Plattenwärmetauschers 1 hat demnach eine erhöhte Andruckkraft des Plattenwärmetauschers 1 gegen den Körper 20 und somit auch eine Zunahme der Dichtwirkung bei den Axialdichtungen 21 zur Folge.The plate heat exchanger introduced through the passage 15 1 penetrating screw 16 is in the body 20 in a Threaded hole 25 screwed in. Preferably be used Anchoring the plate heat exchanger 1 to the body 20 four, each in the area of a corner of the plate heat exchanger 1 arranged tie rod 16 used to be as uniform as possible To achieve distribution of the fastening forces. Even if high pressures occur, the plate heat exchanger can 1 do not lift off the connected body 20, since the Tie rods 16 occurring due to their high tensile strength Volume expansions of the plate heat exchanger 1 from that Body 20 facing away from the top of the plate heat exchanger 1 counteract. A volume expansion of the plate heat exchanger 1 therefore has an increased pressure force of the plate heat exchanger 1 against the body 20 and thus also an increase the sealing effect in the axial seals 21 result.

Statt die Durchlässe 15, wie im Ausführungsbeispiel, innerhalb der üblicherweise rechteckigen Kontur der Wärmetauscherplatten 2 bzw. 2' anzuordnen, können auch spezielle Ausbuchtungen oder Augen außen an den Wärmetauscherplatten 2 bzw. 2' vorgesehen sein, in denen sich die Öffnungen 6 mit ihren Kragen 7 bzw. 7' zur Ausbildung der Durchlässe 15 befinden. Auf diese Weise werden zwar auch die Wärmetauscherplatten 2 bzw. 2' von den Zugankern 16 durchdrungen, jedoch ohne dabei den inneren Aufbau des Plattenwärmetauschers 1 und die Durchströmungskreisläufe zu beeinflussen.Instead of the passages 15, as in the exemplary embodiment, inside the usually rectangular contour of the heat exchanger plates Arrange 2 or 2 'can also special Bulges or eyes on the outside of the heat exchanger plates 2 or 2 'are provided, in which the openings 6 with their collar 7 and 7 'are located to form the passages 15. In this way, the heat exchanger plates 2 or 2 'penetrated by the tie rods 16, however without the internal structure of the plate heat exchanger 1 and to influence the flow circuits.
