Description

Die Erfindung betrifft einen Ladeluft/Kühlmittel-Kühler in Paketbauweise nach dem Oberbegriff des Patentanspruches 1. Ein derartiger Ladeluft/Kühlmittel-Kühler wurde durch die DE-A 196 51 625 der Anmelderin bekannt.The invention relates to a charge air / coolant radiator in packaged construction according to the preamble of claim 1. Such a charge air / coolant radiator was by the DE-A 196 51 625 the applicant known.

Ladeluftkühler in so genannter Paketbauweise werden insbesondere bei Großmotoren eingesetzt, wobei die Ladeluft durch ein flüssiges Kühlmittel gekühlt wird. Diese Ladeluftkühler werden in Ganzaluminiumbauweise hergestellt und verlötet, wobei ein quaderförmig ausgebildeter Kühlerblock und die zugehörigen Anschlussstutzen für die Ladeluft und das Kühlmittel getrennt hergestellt werden. Der Kühlerblock besteht aus einer Vielzahl von aufeinander geschichteten Blechen, zwischen denen Leisten zur Bildung von Strömungskanälen und zur Abstandshaltung angeordnet sind. Der fertig gestapelte Block wird dann in einem Lötofen gelötet. Die Strömungskanäle für die Ladeluft weisen im Inneren Wellrippen oder Turbulenzeinlagen auf, zur Verbesserung der Wärmeübertragung und zur Steigerung der Innendruckfestigkeit. Die Kühlkanäle weisen einen geringeren Strömungsquerschnitt als die Ladeluftkanäle auf und werden durch Zwischenleisten und äußere Abschlussleisten begrenzt. Die Wärmeübertragung zwischen Kühlmittel und Ladeluft erfolgt im Kreuzstrom, d. h. die Kühlmittel- und Ladeluftkanäle verlaufen senkrecht zueinander. Ein derartiger Ladeluftkühler wurde durch die o. g. DE-A 196 51 625 der Anmelderin bekannt. Die Kühlkanäle für das flüssige Kühlmittel bei dem bekannten Ladeluftkühler weisen einen rechteckförmigen Querschnitt auf, da die zwischen den benachbarten Blechen angeordneten Zwischenleisten ebenfalls einen rechteckigen Querschnitt aufweisen. Problematisch bei diesen Wärmeübertragern sind die instationären Zustände, insbesondere auf der Ladeluftseite, die durch starke Temperaturwechsel mit hohen Temperaturdifferenzen und Temperaturspitzen zu Überhitzungen des Kühlmittels, d. h. zu lokalen Siedepunktüberschreitungen mit Dampfblasenbildung führen. Dies ist unbedingt zu vermeiden.Intercoolers in so-called package design are used in particular for large engines, the charge air is cooled by a liquid coolant. These intercoolers are manufactured and soldered in Ganzaluminiumbauweise, with a parallelepiped radiator block and the associated connecting pieces for the charge air and the coolant are made separately. The cooler block consists of a plurality of stacked sheets, between which bars are arranged to form flow channels and for spacing. The finished stacked block is then soldered in a soldering oven. The flow channels for the charge air have inside corrugated ribs or turbulence inserts, to improve the heat transfer and to increase the internal pressure resistance. The cooling channels have a smaller flow cross section than the charge air ducts and are limited by intermediate strips and outer end strips. The heat transfer between coolant and charge air takes place in cross flow, ie the coolant and charge air ducts are perpendicular to each other. Such a charge air cooler was by the above DE-A 196 51 625 the applicant known. The cooling channels for the liquid coolant in the known charge air cooler have a rectangular cross-section, since the intermediate strips arranged between the adjacent sheets also have a rectangular cross-section. The problem with these heat exchangers are the transient conditions, especially on the charge air side, which lead to overheating of the coolant by strong temperature changes with high temperature differences and temperature peaks, ie local boiling point excesses with vapor bubble formation. This is absolutely to be avoided.

Ein ähnlicher Wärmeübertrager in Paketbauweise, ebenfalls ein Ladeluftkühler wurde durch die DE-C 196 44 586 der Anmelderin bekannt. Unterschiedlich sind dabei die Kühlkanäle, welche durch ein plattenförmiges Strangpressprofil gebildet sind. Die Kanalquerschnitte sind dabei rechteckig oder oval, was jedoch primär fertigungstechnische Gründe (Extrusion) hat.A similar heat exchanger in package design, also a charge air cooler was through the DE-C 196 44 586 the applicant known. Different are the cooling channels, which are formed by a plate-shaped extruded profile. The channel cross sections are rectangular or oval, but this has primarily manufacturing reasons (extrusion).

Es ist Aufgabe der vorliegenden Erfindung, einen Kühlerblock der eingangs genannten Art derart zu verbessern, dass lokale Überhitzungen möglichst vermieden werden:It is an object of the present invention to improve a radiator block of the type mentioned in such a way that local overheating is avoided as possible:

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß sind die insbesondere als Leisten ausgebildeten Zwischen- und Abschlussbereiche der Kühlkanäle auf ihren Kühlmittelseiten mit einem Rillenprofil versehen. Durch dieses Rillenprofil ergibt sich eine Ausrundung des Rechteckquerschnittes auf dessen Schmalseite.This object is solved by the features of claim 1. According to the invention, the intermediate and end regions of the cooling channels, which are designed in particular as strips, are provided with a groove profile on their coolant sides. By this groove profile results in a rounding of the rectangular cross-section on the narrow side.

In den Eckbereichen von rechteckförmigen Kanalquerschnitten kann es unter Umständen zu örtlichen Überhitzungen kommen. Durch die erfindungsgemäße Ausrundung des Kanalquerschnittes mittels Rillenprofil wird eine solche Überhitzung vorteilhafterweise weitgehend vermieden.In the corner areas of rectangular channel cross sections, local overheating may occur. As a result of the rounding off of the channel cross section according to the invention by means of a groove profile, such overheating is advantageously largely avoided.

Durch das Rillenprofil ergeben sich einerseits vergleichmäßigte Strömungsverhältnisse im Kühlmittelkanal und andererseits eine thermische Entlastung an den kritischen Eckbereichen. Darüber hinaus wird die Wärmeeinleitung von dem heißen Gas in das im Kühlkanal strömende Kühlmittel auf eine größere Fläche verteilt. Damit wird auch ein lokales Sieden mit schädlicher Dampfblasenbildung des Kühlmittels vermieden.Due to the groove profile, on the one hand, uniform flow conditions in the coolant channel and, on the other hand, thermal relief at the critical corner regions result. In addition, the heat input from the hot gas into the coolant flowing in the cooling passage on distributed a larger area. This also prevents local boiling with harmful vapor bubble formation of the coolant.

Durch eine Stapelbauweise gemäß einer vorteilhaften Ausführungsform wird unter Verwendung von Profilstäben eine Bauweise ermöglicht, bei der auf einfache Bauteile wie Bleche und Leisten zurückgegriffen werden kann.By a stacked construction according to an advantageous embodiment, a construction method is made possible by using profiled bars, can be used in the case of simple components such as sheets and strips.

Eine einstückige Ausbildung der Kühlkanäle gemäß einer anderen Ausführung bewirkt den Vorteil einer einfachen Bauweise mit einer geringen Anzahl von Einzelteilen.A one-piece design of the cooling channels according to another embodiment provides the advantage of a simple construction with a small number of items.

Nach einer vorteilhaften Ausgestaltung der Erfindung weist das Rillenprofil einen parabelförmigen Querschnitt auf, welcher beiderseits von Profilleisten begrenzt wird, die mit dem benachbarten Blech verlötet sind. Dieser Querschnitt stellt einen festigkeitsmäßig und strömungstechnisch günstigen Kompromiss dar.According to an advantageous embodiment of the invention, the groove profile has a parabolic cross section, which is bounded on both sides by profiled strips, which are soldered to the adjacent sheet metal. This cross section represents a compromise in terms of strength and flow.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist das Rillenprofil einen V-förmigen Querschnitt auf, d. h. eine gewisse fertigungstechnische Vereinfachung gegenüber dem Parabel-Profil.According to a further advantageous embodiment of the invention, the groove profile has a V-shaped cross-section, d. H. a certain manufacturing simplification compared to the parabolic profile.

Nach einer weiteren Ausgestaltung der Erfindung ist das Profil einer Zwischenleiste etwa als H-Profil ausgebildet, d. h. mit etwa U-förmigen Einbuchtungen auf jeder Kühlmittelseite.According to a further embodiment of the invention, the profile of an intermediate strip is formed approximately as an H-profile, d. H. with approximately U-shaped indentations on each coolant side.

Fig. 1 zeigt einen Ausschnitt eines vollständig nicht dargestellten Kühlerblocks mit Ladeluftkanälen 1 und quer zu diesen verlaufenden Kühlkanälen 2, welche durch parallel zueinander angeordnete Bleche 3 gebildet werden. Die Ladeluftkanäle 1 werden in Richtung des Pfeils LL von Ladeluft durchströmt und weisen in der Regel hier nicht dargestellte, jedoch aus dem Stand der Technik bekannte Wellrippen auf. Die äußeren Kühlkanäle 2 werden einerseits durch benachbarte Bleche 3 und andererseits durch je eine Abschlussleiste 4 und je eine Zwischenleiste 5 gebildet. Weitere, innen angeordnete, nicht dargestellte Kühlkanäle 2 werden nur durch Zwischenleisten 5 begrenzt. Die Zwischenleisten und die Abschlussleisten sind als Profilstäbe 4, 5 ausgebildet und weisen jeweils auf ihrer Kühlmittelseite, das ist die vom Kühlmittel benetzte Seite, eine Rille 7 bzw. eine Rille 8 auf, d. h. in Längsrichtung der Leisten verlaufende Rillenprofile. Die Kühlkanäle 2 sind damit an ihren Schmalseiten etwas ausgerundet, wodurch sich der benetzte Umfang des Kanalquerschnittes erhöht und ein vergleichmäßigter Wärmeeintrag von der Seite der Ladeluftkanäle 1 erfolgt. Die Profilstäbe 4, 5 sind wie üblich mit den Blechen 3 verlötet und können vorzugsweise als extrudierte Profile hergestellt werden. Fig. 1 shows a section of a radiator block completely not shown with charge air ducts 1 and transverse to these cooling channels 2, which are formed by mutually parallel plates 3. The charge air ducts 1 are traversed by charge air in the direction of the arrow LL and, as a rule, have corrugated ribs, not shown here but known from the prior art. The outer cooling channels 2 are formed on the one hand by adjacent sheets 3 and on the other hand by a respective end strip 4 and one intermediate strip 5 each. Further, arranged inside, not shown cooling channels 2 are limited only by intermediate strips 5. The intermediate strips and the end strips are formed as profile bars 4, 5 and each have on their coolant side, which is the wetted by the coolant side, a groove 7 and a groove 8, ie extending in the longitudinal direction of the strips groove profiles. The cooling channels 2 are thus slightly rounded at their narrow sides, whereby the wetted circumference of the channel cross-section increases and a uniform heat input from the side of the charge air ducts 1 takes place. The profile bars 4, 5 are as usual soldered to the sheets 3 and can be preferably prepared as extruded profiles.

Fig. 2 zeigt eine Einzeldarstellung der Abschlussleiste 4, die das Rillenprofil 7 nur auf einer Seite, d. h. der Kühlmittelseite aufweist. Die flache Seite 4a wird verlötet. Fig. 2 shows a detailed representation of the end strip 4, which has the groove profile 7 only on one side, ie the coolant side. The flat side 4a is soldered.

Fig. 3 zeigt eine Einzeldarstellung der Zwischenleiste 5, welche zwei Rillenprofile 8 auf sich gegenüber liegenden Kühlmittelseiten aufweist. Die flache Seite 5a wird verlötet. Fig. 3 shows an individual view of the intermediate strip 5, which has two groove profiles 8 on opposite coolant sides. The flat side 5a is soldered.

Fig. 4 zeigt eine Einzelheit X aus Fig. 1, d. h. den zur Hälfte dargestellten Profilstab 5 mit dem etwa parabelförmigen Rillenprofil 8, welches seitlich von zwei abgerundeten Profilleisten 9, 10 eingefasst wird, die ihrerseits mit den Blechen 3 verlötet sind. Fig. 4 shows a detail X from Fig. 1 , ie the profiled bar 5 shown halfway with the approximately parabolic groove profile 8, which is laterally bordered by two rounded profile strips 9, 10, which in turn are soldered to the sheets 3.

Leichte Abwandlungen von dem in der Zeichnung dargestellten Rillenprofil, welches etwa einen parabelförmigen Querschnitt aufweist, sind möglich, z. B. als V-Profil oder als H-Profil.Slight modifications of the groove profile shown in the drawing, which has approximately a parabolic cross-section, are possible, for. B. as V-profile or as H-profile.
