Abstract
Description
Die Erfindung betrifft eine Rippe für einen Wärmetauscher nach dem Oberbegriff des Anspruchs 1.The The invention relates to a fin for a heat exchanger according to the preamble of claim 1.
Es sind Wärmetauscher bekannt, bei denen zur Verbesserung der Tauscherleistung Rippen in fluiddurchströmten Kanälen vorgesehen sind. Solche Rippen können zum Beispiel als Glattrippen, Kiemenrippen oder auch als Stegrippen ausgebildet sein. Im ersten Fall wird aufgrund der weitgehend laminaren Strömung eine nur relativ kleine Verbesserung der Tauscherleistung erreicht, wobei aber auch der durch die Rippen bedingte Druckabfall des Fluids verhältnismäßig gering ist. Stegrippen zeigen eine besonders deutliche Verbesserung der Tauscherleistung bei gegebener Baugröße, bedeuten aber auch einen oft unerwünscht großen Druckabfall über den Strömungskanal. Stegrippen kommen unter anderem in Ladeluftkühlern von Kraftfahrzeugen zum Einsatz, und zwar vorwiegend auf der Seite der Ladeluft.It Heat exchangers are known in which for improvement the exchanger power ribs in fluid-flow channels are provided. Such ribs can be for example as Smooth ribs, gill ribs or be designed as rib ribs. In the first case, due to the largely laminar flow achieves only a relatively small improvement in the heat exchanger performance, but also the conditional by the ribs pressure drop of the fluid relative is low. Ribbed ribs show a particularly significant improvement the heat exchanger performance for a given size mean but also an often undesirably large pressure drop over the flow channel. Stegrippen come in among other things Intercoolers of motor vehicles are used, namely mainly on the side of the charge air.

Forschungsbericht
Es ist die Aufgabe der Erfindung, eine Rippe für einen Wärmetauscher anzugeben, deren Wärmeübergang bei gegebenem Druckabfall verbessert ist.It The object of the invention is a rib for a heat exchanger indicate their heat transfer at a given pressure drop is improved.
Diese Aufgabe wird für eine eingangs genannte Vorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch die zwei spiegelsymmetrisch zueinander gekrümmt verlaufende Seitenwände der Auslaschung, die senkrecht zur Wandfläche orientiert sind und ausgehend von der ersten Kante eine der Neigung der Laschenfläche entsprechend abnehmende Höhe aufweisen, wird eine verbesserte Strömung der Luft im Bereich der Auslaschung erzielt, durch die bei gegebenem Druckabfall eine größere Wärmemenge zwischen Luft und Rippe übertragen wird.These Task is for a device mentioned in the invention with the characterizing features of claim 1 solved. By the two mirror-symmetrically curved to each other Side walls of the lashing, perpendicular to the wall surface oriented and starting from the first edge one of the slope the flap surface have correspondingly decreasing height, is an improved flow of air in the area of Leaching achieved by the given pressure drop a larger Transfer amount of heat between air and rib becomes.
In einer bevorzugten Weiterbildung formen die erste Kante, endseitige Kanten der Seitenwände und eine zweite gerade Kante der Wandung ein senkrecht zur Strömungsrichtung orientiertes, von dem ersten Fluid durchströmbares Rechteck aus. Bevorzugt entspricht eine lange Seite des Rechtecks der ersten Kante und hat eine Länge, die etwa dem fünffachen der Länge einer kurzen Seite des Rechtecks entspricht. Besonders vorteilhaft beträgt die Länge der Laschenfläche in Strömungsrichtung etwa das Achtfache der Länge der kurzen Seiten des Rechtecks. Die Auslaschung ist dabei bevorzugt spiegelsymmetrisch bezüglich einer zentralen Symmetrieebene ausgebildet und weiterhin bevorzugt verringert sich eine Breite der Laschenfläche mit zunehmendem Abstand von der ersten Kante. Dabei hat ein bezüglich der ersten Kante entgegengesetztes Ende der Laschenfläche eine kleinste Breite, wobei die kleinste Breite vorteilhaft nicht mehr als ein Zehntel, insbesondere etwa ein zwölftel der Länge der ersten Kante beträgt. Die Krümmung einer der Seitenwände in ihrem Verlauf hat zudem zumindest einen Wendepunkt bezüglich der Krümmungsrichtung. Die Neigung der Laschenfläche gegenüber der Wandfläche beträgt in bevorzugter Ausgestaltung etwa sieben Grad. Insgesamt ist hierdurch eine hutzenartige Auslaschung mit besonders geringem Druckabfall bei guter Wärmeübertragung der durchströmenden Luft bereitgestellt, wie sich durch Versuche gezeigt hat.In a preferred development form the first edge, end-side Edges of the side walls and a second straight edge of the Wall oriented perpendicular to the flow direction, from the first fluid permeable rectangle. Prefers corresponds to a long side of the rectangle of the first edge and has a length that is about five times the length corresponds to a short side of the rectangle. Especially advantageous is the length of the tab surface in Flow direction about eight times the length the short sides of the rectangle. The leaching is preferred mirror-symmetric with respect to a central plane of symmetry formed and further preferably, a width is reduced the tab area with increasing distance from the first Edge. It has one opposite to the first edge End of the tab area a smallest width, with the smallest Width advantageously not more than a tenth, in particular approximately is one-twelfth of the length of the first edge. The curvature of one of the sidewalls in its course also has at least one turning point with respect to the direction of curvature. The inclination of the tab surface relative to the wall surface is in a preferred embodiment about seven degrees. Overall, this is a hood-like leaching with very low pressure drop with good heat transfer of the flowing through Air provided, as has been shown by experiments.
Bei einer besonders bevorzugten Ausführungsform hat die Form der Laschenfläche ausgehend von der ersten Kante in etwa die Parametrisierung [0; 2,500],[0,805; 2,470], [1,610; 2,290], [2,420; 1,910], [3,220; 1,540], [4,030; 1,210], [4,840; 0,980], [5,640; 0,780], [6,440; 0,590], [7,240; 0,400], [8,050; 0,210]. Diese Parametrisierung ist so zu verstehen, dass der erste Wert jeweils den Abstand von der ersten Kante angibt und der zweite Wert jeweils den Abstand von einer zentralen Symmetrieachse zu einer der beiden spiegelsymmetrischen Seitenwände. Diese Parametrisierung entspricht – bis auf einen erheblichen Skalierungsfaktor – der Form des in dem Bericht RM A9L29 der NACA beschriebenen Lufteinlasses.at a particularly preferred embodiment has the shape the tab surface starting from the first edge approximately the parameterization [0; 2.500], [0.805; 2,470], [1.610; 2.290] [2.420; 1,910], [3,220; 1.540], [4.030; 1,210], [4,840; 0.980], [5.640; 0.780], [6.440; 0.590], [7.240; 0.400], [8.050; 0.210]. This parameterization is to be understood that the first value in each case the distance from indicates the first edge and the second value respectively indicates the distance from a central axis of symmetry to one of the two mirror-symmetric ones Side walls. This parameterization corresponds to - to to a significant scaling factor - the shape of the in the report RM A9L29 of the NACA described air intake.
Bei einer vorteilhaften Weiterbildung weist die Rippe in Strömungsrichtung mehrere nacheinander angeordnete Auslaschungen auf, was insbesondere bei langen Rippen eine sinnvolle Anordnung zum Zweck der mehrfachen Umlenkung der Luft über die Rippenstrecke ergibt. Andernfalls würde die Luftströmung nur über einen Teil der Rippe auf vorteilhafte Weise durch die Auslaschung beeinflusst.at an advantageous development, the rib in the flow direction a plurality of successively arranged louvers, which in particular with long ribs a sensible arrangement for the purpose of multiple Deflection of the air over the rib section results. Otherwise the air flow would only be over one Part of the rib influenced in an advantageous manner by the leaching.
Weiterhin vorteilhaft sind in der Wandfläche zumindest zwei Auslaschungen mit unterschiedlicher Öffnungsrichtung vorgesehen. Durch eine solche alternierende Anordnung der Öffnungsrichtung der Auslaschungen kann der Wärmeaustausch mit der strömenden Luft besonders gleichmäßig auf beiden Seiten der Rippe erfolgen.Further advantageous in the wall surface at least two latches are provided with different opening direction. By such an alternating arrangement of the opening direction of the louvers, the heat exchange with the flowing air can be particularly uniform on both Sides of the rib done.
Die Erfindung betrifft zudem einen Wärmetauscher mit zumindest einer erfindungsgemäßen Rippe nach einem der Ansprüche 1 bis 12.The The invention also relates to a heat exchanger with at least a rib according to the invention according to one of the claims 1 to 12.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den nachfolgend beschriebenen Ausführungsbeispielen sowie aus den abhängigen Ansprüchen.Further Advantages and features of the invention will become apparent from the following described embodiments and from the dependent claims.
