Es ist Aufgabe der vorliegenden Erfindung, einen Wärmeübertrager der eingangs genannten Art dahingehend zu verbessern, dass er möglichst einfach und mit geringen Kosten, insbesondere verminderter Teilezahl hergestellt werden kann.It is an object of the present invention to provide a Heat exchanger of the type mentioned above to improve that it possible simple and with low costs, in particular reduced number of parts can be produced.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Patentanspruches 1. Erfindungsgemäß werden die Strömungskanäle sowohl für das Gas, insbesondere das Abgas einer Brennkraftmaschine oder die Ladeluft für die Brennkraftmaschine als auch für das Kühlmittel durch ein mäander-, wellen- oder trapezförmig umgeformtes Metallband und durch das Gehäuse gebildet. Gehäuse und Metallband bilden einen gelöteten Block mit von einander getrennten Strömungskanälen. Vorteilhaft hierbei ist der einfache Aufbau, da nicht für jeden Strömungskanal, sei es für das Gas oder sei es für das Kühlmittel besondere Platten hergestellt, gestapelt und miteinander verlötet werden müssen. Vorteilhaft ist ferner, dass der Querschnitt der Strömungskanäle variabel gestaltet werden kann, z. B. rechteckförmig, trapezförmig, wellenförmig oder dergleichen. Gas- und Kühlmittelkanäle liegen dabei unmittelbar nebeneinander, sodass eine effiziente Wärmeübertragung zwischen beiden Medien erfolgen kann. Die Zahl der Einzelteile für den erfindungsgemäßen Wärmeübertrager ist erheblich reduziert.The solution to this problem results arising from the features of claim 1. According to the invention the flow channels for both the gas, in particular the exhaust gas of an internal combustion engine or the charge air for the Internal combustion engine as well the coolant through a meander, wavy or trapezoidal formed metal band and formed by the housing. Housing and metal band make a soldered one Block with separate flow channels. An advantage here is the simple construction, since not for every flow channel, be it for the gas or be it for the coolant made special plates, stacked and soldered together have to. It is also advantageous that the cross section of the flow channels is variable can be designed, for. B. rectangular, trapezoidal, wavy or like. Gas and coolant channels are doing so directly next to each other, so that efficient heat transfer between both media can be done. The number of items for the heat exchanger according to the invention is considerably reduced.
Nach einer vorteilhaften Weiterbildung der Erfindung werden die Kühlmittelkanäle stirnseitig durch einen kammförmig ausgebildeten Rohrboden verschlossen. Der Rohrboden weist einzelne Zinken oder Trennstege auf, die in die offenen Seiten des Mäanderprofils eingeschoben und anschliessend verlötet werden. Somit ist die Kühlmittelseite gegenüber der Gasseite abgedichtet. Dies vereinfacht die Montage und senkt die Herstellungskosten, da keine Rohrenden eines Rohrbündels in einen Rohrboden eingeführt und eingeschweißt oder eingelötet werden müssen.After an advantageous development the invention, the coolant channels are frontally through a comb-shaped sealed tube bottom closed. The tubesheet has individual Tines or dividers on the open sides of the meander profile inserted and then soldered. Thus, the coolant side across from the gas side sealed. This simplifies assembly and lowers the production costs, since no pipe ends of a tube bundle in introduced a tube sheet and welded or soldered Need to become.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Strömungskanäle etwa rechteckförmig ausgebildet, wobei der Querschnitt für die Gaskanäle vorzugsweise größer gewählt ist. Durch die rechteckige Querschnittsform der Strömungskanäle ergibt sich ein kompakter, druckfester und weitestgehend vibrationsfreier Wärmeübertragerblock. Auch die Verlötung des kammartigen Rohrbodens mit dem Mäanderprofil, d. h. das stirnseitige Verschließen der Kühlmittelkanäle erfolgt aufgrund des Rechteckprofils besonders einfach und sicher. Die rechteckförmigen Strömungskanäle sind insbesondere für die Aufnahme von Turbulenzeinlagen geeignet (s. u.).After a further advantageous Embodiment of the invention, the flow channels are formed approximately rectangular, the cross section for the gas channels is preferably selected to be larger. By the rectangular cross-sectional shape of the flow channels results in a compact, pressure-resistant and largely vibration-free heat exchanger block. Also the soldering of the comb-like tube bottom with the meander profile, d. H. the frontal closure of the coolant channels is due to the rectangular profile especially easy and safe. The rectangular flow channels are especially for recording suitable for turbulence inserts (see below).
Nach einer weiteren Ausgestaltung der Erfindung setzt sich das Gehäuse aus einem U-Profil und einer Abschlussplatte oder aus zwei U-Profilen zusammen, die das Mäanderprofil umschließen. Dies erlaubt eine einfache Montage und sichere Verlötung.According to another embodiment the invention is the case one U-profile and one end plate or two U-profiles together, the meander profile enclose. This allows easy installation and secure soldering.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind am Gehäuse bzw. der Abschlussplatte je ein Verteiler- und ein Sammelkanal für das Kühlmittel angeordnet, die sich quer zu den Kühlmittelkanälen erstrecken. Damit ergibt sich für das Kühlmittel eine gleichmäßige Verteilung über alle Kühlmittelkanäle und damit eine gleichmäßige Kühlung des Abgases. Vorteilhaft hierbei ist auch, wenn die Verteil- bzw. Sammelkanäle direkt aus der Abschlussplatte oder dem U-Profil ausgeformt werden.After a further advantageous Embodiment of the invention are on the housing or the end plate each arranged a distributor and a collecting channel for the coolant, which extend transversely to the coolant channels. This results for the coolant a uniform distribution over all coolant channels and thus a uniform cooling of the Exhaust gas. An advantage here is also when the distribution or collection channels directly be formed from the end plate or the U-profile.
In weiterer Ausgestaltung der Erfindung sind in den Kühlmittelkanälen und/oder Gaskanälen Turbulenzeinlagen angeordnet, um die Wärmeübertragung zu verbessern und – infolge der Verlötung – auch die Druck- und Schwingungsfestigkeit des gesamten Wärmeübertragers (die Turbulenzeinlagen bzw. Rippen wirken als Zuganker).In a further embodiment of the invention, turbulence inserts are arranged in the coolant channels and / or gas channels in order to improve the heat transfer and - due to the soldering - also the pressure and vibration resistance of the entire heat exchanger (the turbulence inserts or ribs act as tie rods).
