StapelscheibenkühlerThe stacked-plate cooler
Die Erfindung betrifft einen Stapelscheibenkühler für Kraftfahrzeuge, mit mehreren aufeinander gestapelten und miteinander verbundenen, insbeson- dere verlöteten, Scheiben, und mit einem durch mehrere Scheiben hindurch verlaufenden Zuführkanal, durch den das zu kühlende Medium dem Stapelscheibenkühler zugeführt und auf einzelne Scheiben verteilt wird.The invention relates to a Stapelscheibenkühler for motor vehicles, with a plurality of stacked and interconnected, in particular soldered, discs, and with a running through several discs through feed channel through which the medium to be cooled is supplied to the Stapelscheibenkühler and distributed to individual discs.
Der Ölzuführkanal eines herkömmlichen Stapelscheibenölkühlers wird zum Beispiel über eine Ölpumpe mit Öl versorgt. Um Verunreinigungen in dem Stapelscheibenölkühler zu vermeiden, kann es sinnvoll sein, das Öl in einem Ölfilter zu filtern, bevor es in den Ölzuführkanal des Stapelscheibenölkühlers gelangt. Aus der deutschen Gebrauchsmusterschrift DE 202 15 258 U1 ist ein Ölmodul für eine Brennkraftmaschine bekannt, in dem Mittel zur Verhin- derung eines Ölrücklaufs in Richtung zur Ölpumpe bei Stillstand der Brennkraftmaschine und Mittel zur Verhinderung eines Ölrücklaufs in Richtung zum Befüllanschluss nach dem Befüllen mit der ersten Ölfüllung vorgesehen sind.The oil supply passage of a conventional stacked-plate oil cooler is supplied with oil, for example, via an oil pump. To avoid contamination in the stacked-plate oil cooler, it may be useful to filter the oil in an oil filter before it enters the oil supply passage of the stacked-plate oil cooler. German utility model DE 202 15 258 U1 discloses an oil module for an internal combustion engine in which means for preventing oil return in the direction of the oil pump when the internal combustion engine is at a standstill and means for preventing oil return in the direction of the filling port after filling with the first Oil filling are provided.

Gemäß der vorliegenden Erfindung wird die Ventileinrichtung in den Stapelscheibenkühler integriert. Dadurch wird der bestehende Bauraum in dem Stapelscheibenkühler für eine zusätzliche Funktion genutzt. Durch die Integration der Ven- tileinrichtung wird somit kein zusätzlicher Bauraum benötigt.The object is achieved in a stacked disc radiator for motor vehicles with several stacked and interconnected, in particular soldered discs, and with a running through several discs feed channel through which the medium to be cooled is supplied to the stacked disc cooler and distributed to individual discs, thereby solved in that a valve device is installed in the feed channel, which prevents a return of the medium to be cooled from the feed channel, for example when the pump of the motor is at a standstill. According to the present invention, the valve means is integrated in the stack disc cooler. As a result, the existing space in the stack disc radiator is used for an additional function. The integration of the valve device thus requires no additional space.

In Figur 1 ist ein erfindungsgemäßer Stapelscheibenölkühler 1 in der Drauf- sieht dargestellt. Der Stapelscheibenölkühler 1 umfasst eine Grundplatte 4, die den Stapelscheibenölkühler 1 auf einer Seite begrenzt. Die Grundplatte 4 hat die Gestalt eines Rechtecks, in dessen Ecken jeweils ein Durchgangsloch 6, 7, 8, 9 ausgespart ist. Die Durchgangslöcher 6 bis 9 dienen zur Befestigung des Stapelscheibenölkühlers 1 an einem (nicht dargestellten) Kraft- fahrzeug.FIG. 1 shows a stacked-plate oil cooler 1 according to the invention in the top view. The stacked-plate oil cooler 1 comprises a base plate 4 which limits the stacked-plate oil cooler 1 on one side. The base plate 4 has the shape of a rectangle, in each of whose corners a through hole 6, 7, 8, 9 is recessed. The through-holes 6 to 9 serve for fastening the stacked-plate oil cooler 1 to a motor vehicle (not shown).
Auf der der Grundplatte 4 entgegengesetzten Seite wird der Stapelscheibenölkühler 1 von einer Abdeckplatte 12 begrenzt. In der Abdeckplatte 12 sind zwei Vertiefungen 14, 15 vorgesehen, die im Wesentlichen die Gestalt von Kugelabschnitten aufweisen. Außerdem sind in der Abdeckplatte ein Ölzuführkanal 18 und ein Ölabführkanal 19 eingezeichnet, die tatsächlich in der Draufsicht jedoch nicht sichtbar sind, sondern durch die Abdeckplatte 12 verdeckt werden. Der Ölzuführkanal 18 dient dazu, dem Stapelscheibenölkühler 1 Öl zuzuführen, das in den Stapelscheiben des Stapelscheibenölküh- lers 1 mit Hilfe von Kühlmittel oder Luft abgekühlt wird. Der Ölabführkanal 19 dient dazu, das in dem Stapelscheibenölkühler 1 abgekühlte Öl wieder abzuführen. Gemäß der vorliegenden Erfindung ist in dem Ölzuführkanal 18 eine Ventileinrichtung 20 angeordnet.On the base plate 4 opposite side of the stacked-plate oil cooler 1 is bounded by a cover plate 12. In the cover plate 12, two recesses 14, 15 are provided, which have substantially the shape of spherical sections. In addition, in the cover plate, an oil feed channel 18 and a Ölabführkanal 19 are located, which are actually not visible in plan view, but are covered by the cover plate 12. The oil feed channel 18 serves to supply oil to the stacked-plate oil cooler 1 which is cooled in the stacking disks of the stacked-plate oil cooler 1 by means of coolant or air. The Ölabführkanal 19 serves to dissipate the cooled in the stacked plate oil cooler 1 oil again. According to the present invention, a valve device 20 is disposed in the oil supply passage 18.
In der in Figur 2 dargestellten Seitenansicht sieht man, dass zwischen der Grundplatte 4 und der Abdeckplatte 12, die auch als Abdeckscheibe bezeichnet wird, eine Vielzahl von Stapelscheiben 21 , 22, 23, 24 angeordnet sind. Die Stapelscheiben 21 bis 24 haben die Gestalt von übereinander gestapelten wannenförmigen Platten, deren Ränder sich gegenseitig überlap- pen und miteinander verlötet sind. Zwischen jeweils zwei benachbarten Stapelscheiben werden auf diese Weise Hohlkammem gebildet, die abwechselnd von den an der Wärmeübertragung beteiligten Medien durchströmt sind. Bei dem zu kühlenden Medium handelt es sich vorzugsweise um Öl. In dem erfindungsgemäßen Stapelscheibenölkühler 1 können aber auch ande- re Medien abgekühlt werden. Als Kühlmittel wird vorzugsweise Wasser mit bekannten Zusätzen verwendet. Statt eines flüssigen Kühlmittels kann aber auch Luft zum Abkühlen des Öls verwendet werden.In the side view shown in Figure 2 it can be seen that between the base plate 4 and the cover plate 12, which is also referred to as a cover, a plurality of stacking disks 21, 22, 23, 24 are arranged.

In the through hole 36, a closure ring 38 is pressed, which has a rectangular cross-section. On the locking ring 38, a sealing surface 39 is formed for an O-ring 40. The O-ring 40 is attached to a valve body 42, which is pressed by a helical compression spring 44 against the locking ring 38. The helical compression spring 44 is clamped between the valve body 42 and the cover plate 12.
Der Verschlussring 38, der O-Ring 40, der Ventilkörper 42 und die Schraubendruckfeder 44 bilden eine Rückschlagventileinrichtung, die einen Rückstrom von Öl aus dem Ölzuführkanal 18 verhindert. Der Ventilkörper 42 wird durch die Schraubendruckfeder 44 so gegen den Verschlussring 38 gedrückt, dass der O-Ring 40 in abdichtender Art und Weise an der Dichtfläche 39 anliegt. Wenn der Druck an dem Ventilkörper 42 die Vorspannkraft der Schraubendruckfeder 44 überwindet, dann öffnet der Ventilkörper 42, so dass Öl an dem Ventilkörper vorbei in den Ölzuführkanal 18 gelangt. Sobald der Druck nachlässt, weil zum Beispiel eine zur Ölförderung verwendete Pumpe abgeschaltet wird, dann sorgt die Vorspannkraft der Schrauben- druckfeder 44 dafür, dass der Ventilkörper 42 wieder schließt.The locking ring 38, the O-ring 40, the valve body 42 and the helical compression spring 44 form a check valve device which prevents a return flow of oil from the oil supply channel 18. The valve body 42 is pressed by the helical compression spring 44 against the locking ring 38 so that the O-ring 40 abuts the sealing surface 39 in a sealing manner. When the pressure on the valve body 42 overcomes the biasing force of the helical compression spring 44, the valve body 42 opens, so that oil passes the valve body past the oil supply passage 18. As soon as the pressure decreases, for example because a pump used for oil delivery is switched off, then the biasing force of the helical compression spring 44 ensures that the valve body 42 closes again.
In Figur 4 sind die Schraubendruckfeder 44, der Ventilkörper 42 und O-RingIn Figure 4, the helical compression spring 44, the valve body 42 and O-ring
40 alleine in Explosionsdarstellung gezeigt. In Figur 4 sieht man, dass der40 alone shown in exploded view. In Figure 4 it can be seen that the
Ventilkörper 42 einen Schließkörper 45 aufweist, der im Wesentlichen die Gestalt einer Kreisscheibe 46 hat. Von dem Schließkörper 45 gehen radial außen vier Verbindungsstege 51 bis 54 aus. Die Verbindungsstege 51 bis 54 verbinden einen Führungsring 56, der im Wesentlichen den gleichen Außendurchmesser wie die Kreisscheibe 46 aufweist, mit dem Schließkörper 45. Der Führungsring 56 und die Verbindungsstege 51 bis 54 bilden eine Art Führungskäfig für den Ventilkörper 42 in dem Ölzuführkanal 18. Außerdem dient der Führungskäfig zur Aufnahme des der Grundplatte 4 zugewandten Endes der Schraubendruckfeder 44.Valve body 42 has a closing body 45 which has substantially the shape of a circular disc 46. From the closing body 45 go radially outside four connecting webs 51 to 54 off. The connecting webs 51 to 54 connect a guide ring 56, which has substantially the same outer diameter as the circular disc 46, with the closing body 45. The guide ring 56 and the connecting webs 51 to 54 form a kind of guide cage for the valve body 42 in the oil feed channel 18. In addition serves the guide cage for receiving the base plate 4 facing the end of the helical compression spring 44th
In Figur 5 ist der Ventilkörper 42 in der Draufsicht dargestellt. In der Drauf- sieht ist die Lage eines Schnitts Vl-Vl angedeutet, der in Figur 6 dargestellt ist. In der Schnittansicht der Figur 6 sieht man, dass radial außen in dem Schließkörper 45 auf der dem Führungsring 56 abgewandten Seite eine Ringnut 58 ausgebildet ist, die zur Aufnahme des O-Rings 40 (siehe Figur 4) dient.In Figure 5, the valve body 42 is shown in plan view. In the top view, the position of a section Vl-Vl is indicated, which is shown in FIG. In the sectional view of FIG. 6, it can be seen that an annular groove 58, which serves to receive the O-ring 40 (see FIG. 4), is formed radially on the outside in the closing body 45 on the side facing away from the guide ring 56.
In Figur 7 ist der erfindungsgemäße Stapelscheibenölkühler 1 in einer Explosionsdarstellung gezeigt. In dieser Darstellung sieht man, dass die Grundplatte 4 ein Durchgangsloch 60 aufweist, das zum Zuführen von Kühlmittel dient. Der Verschlussring 38, der O-Ring 40, der Ventilkörper 42 und die Schraubendruckfeder 44 bilden eine Rückschlagventileinrichtung, die in den Ölzuführkanal (18 in Figur 3) eingebaut ist. Beim Einbau wird zunächst die Schraubendruckfeder 44 zusammen mit dem Ventilkörper 42 und dem daran angebrachten O-Ring 40 in den Ölzuführkanal eingeführt. Anschließend wird der Verschlussring 38 in das Durchgangsloch 36 der Grundplatte 4 einge- presst. Durch die Rückschlagventileinrichtung wird ein unerwünschter Öl- rücklauf bei einem Stillstand der Ölpumpe verhindert. Der Ventilkörper 42 kann als Kunststoff-Spritzgussteil oder als Metallteil, wie beispielsweise Blechteil oder Drehteil, ausgeführt sein.FIG. 7 shows the stacked-plate oil cooler 1 according to the invention in an exploded view. In this illustration, it is seen that the base plate 4 has a through hole 60 serving for supplying coolant. The lock ring 38, the O-ring 40, the valve body 42 and the helical compression spring 44 constitute a check valve device installed in the oil supply passage (18 in FIG. 3). When installing the helical compression spring 44 is first introduced together with the valve body 42 and the attached O-ring 40 in the oil supply passage. Subsequently, the locking ring 38 is pressed into the through hole 36 of the base plate 4. By the check valve means an undesirable oil return at a standstill of the oil pump is prevented. The valve body 42 may be designed as a plastic injection molded part or as a metal part, such as sheet metal part or rotary part.
In den Figuren 1 bis 7 sind Ausführungsbeispiele eines Stapelscheibenkühlers als Stapelscheibenölkühler beschrieben. Die Erfindung kann jedoch auch für Stapelscheibenkühler verwendet werden, bei welchen ein anderes zu kühlendes Medium verwendet wird. Die beispielhafte Beschreibung der Erfindung anhand eines Ölkühlers stellt jedoch keine Beschränkung auf die- sen Einsatzzweck dar. In the figures 1 to 7 embodiments of a Stapelscheibenkühlers are described as Stapelscheibenölkühler. However, the invention can also be used for stacked disc radiators in which another medium to be cooled is used. However, the exemplary description of the invention with reference to an oil cooler does not represent a restriction to this application.
