This is the surface provided the rib element particularly large. Depending on the embodiment and material pairing may also affect the rib member to abut the inner wall of the housing or else be firmly connected to the housing wall, z. B. cohesively.
In vorteilhafter Weiterbildung hat das Rippenelement dabei einen randseitigen Abschnitt, wobei zwischen dem Gehäuse und dem randseitigen Abschnitt ein vergrößerter Abstand zur bevorzugten Durchleitung des zweiten Fluids vorgesehen ist. Hierdurch kann der Strom des zweiten Fluids gezielt durch die entsprechende Ausformung der Rippenelemente beeinflusst werden; z. B. kann der Strom unter mehreren Umlenkungen durch das Gehäuse geleitet werden, um eine optimierte Wärmeübertragung bei möglichst kleinem Bauraum zu ermöglichen.In Advantageous development, the rib element has a peripheral side Section, being between the housing and the marginal section an increased distance to the preferred passage the second fluid is provided. This allows the flow of second fluid targeted by the corresponding shape of the rib elements to be influenced; z. B. can the power under several deflections be routed through the housing for optimized heat transfer to allow for the smallest possible space.
Allgemein vorteilhaft folgt dabei das zweite Fluid innerhalb des Gehäuses zumindest einem Hauptströmungspfad, wobei die Richtung des Hauptströmungspfads durch das Rippenelement umgelenkt ist.Generally Advantageously, the second fluid follows within the housing at least one main flow path, wherein the direction the main flow path is deflected by the rib member is.
In einer besonders bevorzugten Ausführungsform besteht das Gehäuse im Wesentlichen aus einem Kunststoff. Hierdurch ergibt sich eine hohe Gesichtsersparnis und günstige Fertigung, wobei durch entsprechende Ausfor mung von Adaptern für Anbauteile oder ähnliche Maßnahmen im Zuge einer Herstellung des Kunststoffgehäuses insbesondere als Spritzguss-Formteil weitere Bauraum- und Kosteneinsparungen erzielbar sind. Insbesondere im Fall von Abgas-Wärmetauschern ist das Vorsehen von Kunststoffgehäusen gegenüber den bekannten Stand der Technik eine Verbesserung.In a particularly preferred embodiment is the Housing essentially made of a plastic. hereby results in a high saving of face and cheap production, wherein by appropriate Ausfor determination of adapters for attachments or similar measures during manufacture the plastic housing in particular as an injection molded part Further space and cost savings can be achieved. Especially in the case of exhaust heat exchangers, the provision of plastic housings an improvement over the known prior art.
Bei einer im Interesse einer einfachen und günstigen Herstellung besonders vorteilhaften Ausführungsform ist zwischen dem Bodenteil und dem Gehäuse eine insbesondere ringförmige Dichtung zur Abdichtung des zweiten Fluids vorgesehen. Besonders bevorzugt ist dabei das Gehäuse unter dichtender Anlage an der Dichtung in einer axialen Richtung gegenüber dem Bodenteil bewegbar. Hierdurch können z. B. unterschiedliche Wärmeausdehnungen von Tauscherrohren und Gehäuse auf einfache Weise kompensiert werden.at one in the interest of a simple and inexpensive production Particularly advantageous embodiment is between the Bottom part and the housing a particular annular Seal provided for sealing the second fluid. Especially The housing is preferably under sealing contact at the seal in an axial direction opposite to the Movable bottom part. As a result, z. B. different Thermal expansions of exchanger tubes and housing be easily compensated.
In einer vorteilhaften Detailgestaltung ist das Rippenelement mit zumindest einem der Tauscherrohre stoffschlüssig verbunden, insbesondere mittels Verlötung oder Verschweißung. Neben einer besonders sicheren und langlebigen Halterung ist hierdurch ein besonders guter Wärmeübergang zwischen Tauscherrohr und Rippenelement gewährleistet.In an advantageous detail, the rib element is at least one of the exchanger tubes materially connected, in particular by soldering or welding. In addition to one Particularly safe and durable bracket is thus a special good heat transfer between exchanger tube and Ensured rib element.
Allgemein bevorzugt ist ein Kastenelement insbesondere stoffschlüssig mit dem Bodenteil verbunden, wobei das Kastenelement einen Anschluss für das erste Fluid aufweist. Hierdurch ist der erfindungsgemäße Wärmetauscher einfach und günstig herstellbar, z. B. indem zunächst das Rippenelement an dem Tauscherrohrbündel festgelegt wird, nachfolgend das Rohrbündel an dem Bodenteil und nachfolgend das Bodenteil an dem Kastenelement. Die Festlegung kann zunächst rein mechanischer Art sein, wobei die Bauteile z. B. aus lotplattierten Blechen oder Ähnlichem bestehen können, insbesondere wenn das Material der genannten Bauteile Aluminium ist. Insbesondere im Fall von Stahl, bevorzugt nichtrostendem Stahl, als Material werden die Bauteile in der genannten Montagereihenfolge jeweils miteinander verschweißt.Generally, a box element is in particular materially connected to the bottom part, wherein the box element has a connection for the first fluid.
