Abstract

Die Erfindung geht aus von einem Strömungsleitelement (50) zur Anordnung in einem Wärmetauscher (10, 10') zu einer den Wärmetausch beeinflussenden Strömungsführung eines Fluids entlang einer Hauptströmungslängsrichtung (3) von einem Fluideintritt (24.1) zu einem Fluidaustritt (24.2). Gemäß dem Konzept der Erfindung weist das Strömungsleitelement (50) eine sich in Hauptströmungslängsrichtung (3) erstreckende flächlige Grundebene (52) auf, wobei sich über die Grundebene (52) hinaus wenigstens teilweise seitliche Begrenzungsstrukturen (57) zur Bildung wenigstens eines Strömungspfades (59, P1 - P7) erheben. Zur Beeinflussung der Strömungsführung in Hauptströmungslängsrichtung (3) weist der wenigstens eine Strömungspfad (59, P1 - P7) einen strömungsaufwärtigen ersten Abstand (Aein) der seitlichen Begrenzungsstrukturen (57) und einen strömungsabwärtigen zweiten Abstand (Aaus) der seitlichen Begrenzungsstrukturen (57) auf, wobei die Abstände derart unterschiedlich sind, dass ein dem Strömungspfad zugeordneter Druckverlust des Fluids von einer dem strömungsaufwärtigen ersten Abstand zugeordneten Stelle zu einer dem strömungsabwärtigen zweiten Abstand zugeordneten Stelle anders als ein Druckverlust eines gedachten Strömungspfades mit im Wesentlichen gleich beabstandeten Begrenzungsstrukturen ist. Vorteilhaft ist ein solcher Strömungspfad geeignet, das Fluid vergleichsweise stärker in Bereiche besonders hohen Wärmetausches und/oder mit einer Kühlmittelunterversorgung zu führen bzw. das Fluid vergleichsweise schwächer Bereichen mit vergleichsweise geringem Wärmetausch und/oder mit einer Kühlmittelüberversorgung zuzuführen.

The invention is based on a flow guide element (50) for arranging in a heat exchanger (10, 10 ') a flow guidance of a fluid influencing the heat exchange along a main flow longitudinal direction (3) from a fluid inlet (24.1) to a fluid outlet (24.2). According to the concept of the invention, the flow guide element (50) has a flat base plane (52) extending in the main flow longitudinal direction (3), wherein at least partially lateral boundary structures (57) extend beyond the base plane (52) to form at least one flow path (59, 59; P1 - P7). For influencing the flow guide in the main flow longitudinal direction (3) of the at least one flow path (59, P1 - P7) includes an upstream first distance (A a) of the lateral boundary structure (57) and a downstream second distance (A) for the lateral boundary structure (57) wherein the distances are different such that a pressure loss of the fluid associated with the flow path from a location associated with the upstream first distance to a location associated with the downstream second distance is other than a pressure loss of an imaginary flow path having substantially equally spaced confining structures. Advantageously, such a flow path is suitable for guiding the fluid comparatively more strongly into regions of particularly high heat exchange and / or with a coolant undersupply or for supplying the fluid to comparatively weaker regions with comparatively little heat exchange and / or with a coolant oversupply.
