Abstract
Die
Erfindung betrifft einen Stapelscheibenwärmeübertrager, insbesondere einen Ölkühler für Kraftfahrzeuge,
bestehend aus einem Block (1) auf- und ineinander gestapelten Stapelscheiben
(2), die jeweils erste und zweite Durchgangsöffnungen zur Bildung von Verteiler-
und Sammelkanälen
(8, 9) aufweisen, und einer äußeren Abdeckscheibe
(12).
Es wird vorgeschlagen, dass die Abdeckscheibe (12) im Bereich
mindestens eines Sammelkanals (8) eine stufenförmige Einprägung (13) aufweist.The invention relates to a stacked plate heat exchanger, in particular an oil cooler for motor vehicles, consisting of a block (1) and stacked stacking discs (2), each having first and second through holes for forming distribution and collection channels (8, 9), and an outer cover (12).
It is proposed that the cover plate (12) has a stepped embossment (13) in the region of at least one collecting channel (8).

Es ist Aufgabe der vorliegenden Erfindung, die Festigkeit eines Stapelscheibenwärmeübertragers der eingangs genannten Art, insbesondere im Bereich der Abdeckscheibe zu erhöhen, möglichst ohne Gewichtszuwachs.It Object of the present invention, the strength of a Stapelscheibenwärmeübertragers of the type mentioned, in particular in the field of cover to increase, as possible without Weight gain.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass zusätzlich zu der bekannten kalottenförmigen Ausprägung eine stufenförmige Ausprägung vorgesehen ist, welche so weit in den Sammelkanal hineinreicht, dass eine Verlötung mit der letzten und der vorletzten Stapelscheibe möglich ist. Damit wird der Vorteil einer wesentlichen Festigkeitssteigerung erreicht: in Messungen konnte nachgewiesen werden, dass die maximalen Spannungen um ca. 10 % und die maximalen Verformungen um ca. 15 % reduziert wurden. Die Materialstärke der Abdeckscheibe konnte konstant gehalten werden, d. h. das Gewicht des Wärmeübertragers wurde nicht erhöht. Die während des Betriebes auf die Abdeckscheibe wirkenden Druckkräfte werden durch den inneren Verbund der Stapelscheiben aufgenommen.These The object is solved by the features of claim 1. According to the invention, it is provided that in addition to the known dome-shaped shaping a step-shaped shaping is provided, which extends so far into the collecting channel, that a soldering with the last and the penultimate stacking disc is possible. This is the advantage of a substantial increase in strength achieved: in measurements could be proven that the maximum Tensions around 10% and maximum deformations around 15 % were reduced. The material thickness of the cover could kept constant, d. H. the weight of the heat exchanger was not increased. The while the operation on the cover disc acting pressure forces are taken up by the inner composite of the stacking disks.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist die stufenförmige Einprägung in der Abdeckscheibe derart ausgebildet, dass sie mit einer Ringfläche auf der äußersten Stapelscheibe im Bereich einer Durchtrittsöffnung aufliegt, wobei die äußerste Stapelscheibe auf einer napfförmigen Ausnehmung der benachbarten Stapelscheibe aufliegt. Damit ist die Abdeckscheibe – indirekt – mit der vorletzten Stapelscheibe verlötet, so dass die Innendruckkräfte auf den Stapel abgesetzt werden können.To an advantageous embodiment of the invention, the stepped embossing in the cover plate is formed so that it with an annular surface the utmost Stacking disc rests in the region of a passage opening, wherein the outermost stacking disc on a cup-shaped Recess of the adjacent stacking disc rests. This is the Cover disc - indirectly - with the Soldered penultimate stacking disc, so that the internal pressure forces can be deposited on the stack.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die stufenförmige Einprägung eine weitere Ausprägung, vorzugsweise kalotten- oder kegelstumpfförmig auf, welche in den Sammelkanal hineinragt. Dadurch wird eine weitere Verstärkung der Abdeckscheibe (Formsteifigkeit) erreicht. In Messungen konnten eine 50-%-ige Reduzierung der maximalen Spannung und eine Verringerung der maximalen Verformung der Abdeckscheibe um 15 % nachgewiesen werden.To a further advantageous embodiment of the invention, the stepped impressing another characteristic, preferably dome or truncated cone on, which protrudes into the collection channel. This will be another reinforcement the cover (form stiffness) reached. In measurements could a 50% reduction in maximum stress and a reduction The maximum deformation of the cover disc has been proven to be 15% become.
Die erfindungsgemäße stufenförmige Einprägung sowie die kalottenförmige Ausprägung können vorzugsweise kreisförmig oder oval ausgebildet sein. Die Erfindung ist auf Stapelscheibenwärmeübertrager der eingangs genannten Art, d. h. mit glatten und mit profilierten Stapelscheiben anwendbar.The stepped embossing according to the invention and the dome-shaped expression can preferably be circular or oval. The invention is to stacked plate heat exchanger of the type mentioned, ie with smooth th and with profiled stacking discs applicable.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigenOne embodiment The invention is illustrated in the drawing and will be described below described in more detail. Show it
Der Stapelscheibenwärmeübertrager wird vorzugsweise aus Aluminium bzw. Aluminiumlegierungen hergestellt und ist daher hart lötbar.Of the The stacked-plate heat exchanger is preferably made of aluminum or aluminum alloys and is therefore hard solderable.
Abweichend vom dargestellten Ausführungsbeispiel, können statt der glatten Stapelscheiben mit Turbulenzeinlagen auch profilierte Stapelscheiben, insbesondere mit Wellprofilen im Rahmen der Erfindung verwendet werden.deviant from the illustrated embodiment, can instead of the smooth stacking disks with turbulence inserts also profiled Stacking disks, in particular with corrugated profiles in the context of the invention be used.
