According to the invention, the cylinder head comprises a cooling passage (1a, 1b, 1c, 1d) through which a coolant can flow for cooling certain areas of the cylinder head, the cooling passage (1a, 1b, 1c, 1d) being formed at least in regions as a grid structure (2) is.
Description
Die Erfindung betrifft einen Zylinderkopf und ein Herstellungsverfahren für einen Zylinderkopf.The invention relates to a cylinder head and a manufacturing method for a cylinder head.
Aus der
Der erfindungsgemäße Zylinderkopf für einen Verbrennungsmotor umfasst einen Kühlkanal, der durch ein Kühlmittel durchströmbar ist zum Kühlen bestimmter Bereiche des Zylinderkopfes, wobei der Kühlkanal zumindest bereichsweise als Gitterstruktur ausgebildet ist.The cylinder head according to the invention for an internal combustion engine comprises a cooling channel through which a coolant can flow for cooling certain areas of the cylinder head, wherein the cooling channel is formed at least in regions as a lattice structure.
Ein möglicher Vorteil ist, den Kühlkanal mit einem für das Kühlen der Bereiche vorteilhaften Querschnitt auszubilden, und durch die Gitterstruktur die erforderliche Steifigkeit und/oder Stabilität des Zylinderkopfes in diesem Bereich zu gewährleisten. Des Weiteren ermöglicht die Erfindung, Kühlkanäle in Bereichen vorzusehen oder in Bereiche auszudehnen, in denen dies mit Kühlkanälen ohne besondere Maßnahmen aufgrund von mechanischen Anforderungen nicht möglich ist, und auf diese Weise beispielsweise eine Wärmeabfuhr zu verbessern.A possible advantage is to form the cooling channel with a cross section which is advantageous for the cooling of the regions, and to ensure the required rigidity and / or stability of the cylinder head in this region through the grid structure. Furthermore, the invention makes it possible to provide cooling channels in areas or expand into areas in which this is not possible with cooling channels without special measures due to mechanical requirements, and in this way, for example, to improve heat dissipation.
Der Kühlkanal kann, je nach Anforderung, bereichsweise oder vollständig als Gitterstruktur ausgebildet sein. So kann beispielsweise im Querschnitt ein Bereich des Kühlkanals frei bleiben und/oder die Gitterstruktur nur abschnittsweise ausgebildet sein. Vorzugsweise ist die Gitterstruktur nur dort ausgebildet, wo die Gitterstruktur zur Steifigkeit oder Stabilität beitragen muss. Dies hat den Vorteil, eine Behinderung des Durchströmverhaltens des Kühlmittels durch die Gitterstruktur zu verringern.Depending on the requirement, the cooling channel can be formed in regions or completely as a lattice structure. For example, in cross-section, a region of the cooling channel can remain free and / or the lattice structure can be formed only in sections. Preferably, the grid structure is formed only where the grid structure must contribute to rigidity or stability. This has the advantage of reducing the obstruction of the flow-through behavior of the coolant through the lattice structure.
Besonders vorteilhaft ist die Gitterstruktur zumindest bereichsweise, vorzugsweise im Wesentlichen vollständig durch das das Kühlmittel durchströmbar. Die Gitterstruktur ist vorzugsweise in Ihrer Geometrie derart ausgebildet, dass die durch diese gebildete Kanäle oder Räume im Wesentlichen entlang der durch den Kühlkanal vorgegebenen Strömungsrichtung des Kühlmittels ausgerichtet sind.Particularly advantageously, the grid structure is at least partially, preferably substantially completely through which the coolant can flow. The grid structure is preferably formed in its geometry such that the channels or spaces formed by these are aligned substantially along the direction of flow of the coolant through the cooling channel.
Erfindungsgemäß wird die Gitterstruktur oder der gesamte Zylinderkopf durch ein generatives Fertigungsverfahren (engl. „additive manufacturing“) hergestellt. Bevorzugt ist ein SLM-Druckverfahren (Selective Laser Melting / Selektives Laserschmelzen), ohne aber andere Verfahren, insbesondere 3D-Druckverfahren, auszuschließen. Als Pulver kann beispielsweise ein AlSi1 OMg-Pulver verwendet werden.According to the invention, the lattice structure or the entire cylinder head is produced by a generative manufacturing process ("additive manufacturing"). Preference is given to an SLM (Selective Laser Melting) printing method, but excluding other methods, in particular 3D printing methods. As a powder, for example, an AlSi1 OMg powder can be used.
