Abstract

Eine Fluidleitung 1 umfasst einen Kanal 2 zum Durchfluss eines Fluids und ein Verschlusselement 3, das das Durchflussvolumen des Fluids durch den Kanal 2 einstellt. Das Verschlusselcment 3 ist mittels einer geeigneten Befestigung 4 befestigt. Ein Bypass 5 sorgt dafür, dass stets ein bestimmter Volumenstrom vom Leitungsbereich vor dem Verschlusselement 3 in den Leitungsbereich hinter dem Verschlusselement 3 durchfließt, um Temperaturänderungen im Fluid eines Systems (beispielsweise eines Kühlwasserkreislaufs) zum Verschlusselement 3 hin zu transportieren. Das Verschlusselement 3 ändert seine Geometrie in Abhängigkeit von der Temperatur. Das Verschlusselement 3 ist beispielsweise als Bimetallelement oder aus einem Formgedächtniswerkstoff ausgebildet. Das Verschlusselement 3 gemäß der Erfindung ist derart ausgebildet, dass in einem ersten Zustand bei einer Temperatur unterhalb einer Schwellentemperatur Tg ein praktisch vollständig verschlossener Zustand s1 (s1 etwa null) realisiert ist, während oberhalb der Schwellentemperatur Tg ein maximal geöffneter Zustand s2 erreicht wird. Dieses nichtlineare Verhalten mit praktisch zwei diskreten metastabilen Zuständen kann beispielsweise durch eine geeignete Kontur der Oberfläche des Verschlusselements 3 eingestellt werden.

A fluid line 1 comprises a channel 2 for the passage of a fluid and a closure element 3, which adjusts the flow volume of the fluid through the channel 2. The closure element 3 is fastened by means of a suitable attachment 4. A bypass 5 ensures that a certain volume flow always flows from the line area in front of the closure element 3 into the line area behind the closure element 3, in order to transport temperature changes in the fluid of a system (for example a cooling water circuit) to the closure element 3. The closure element 3 changes its geometry as a function of the temperature. The closure element 3 is formed, for example, as a bimetallic element or from a shape memory material. The closure element 3 according to the invention is designed such that in a first state at a temperature below a threshold temperature T g a practically completely closed state s 1 (s 1 is approximately zero) is realized, while above the threshold temperature T g a maximum open state s 2 is reached. This nonlinear behavior with practically two discrete metastable states can be set, for example, by a suitable contour of the surface of the closure element 3.
