Abstract
(DE)
Die Erfindung betrifft eine Trennwand (5) zum Unterteilen eines Heizvolumens (3) eines Leistungsschalters (1) in ein erstes Teilvolumen (3.1) und ein zweites Teilvolumen (3.2). Die Trennwand (5) umfasst wenigstens eine Wandöffnung (6), die eine Gasströmung (H) zwischen den Teilvolumina (3.1, 3.2) ermöglicht. Die Wandöffnung (6) weist eine von einer Druckdifferenz zwischen einem Druck in dem ersten Teilvolumen (3.1) und einem Druck in dem zweiten Teilvolumen (3.2) abhängige aerodynamisch wirksame Öffnungsfläche auf.
(EN)
The invention relates to a separating wall (5) for dividing a heating volume (3) of a power circuit (1) into a first sub-volume (3.1) and a second sub-volume (3.2). The separating wall (5) comprises at least one wall opening (6) which allows a flow of gas (H) between the sub-volumes (3.1, 3.2), and the wall opening (6) has an aerodynamically active opening surface based on a pressure difference between the pressure in the first sub-volume (3.1) and the pressure in the second sub-volume (3.2).
(FR)
L'invention concerne une paroi de séparation (5) destinée à diviser un volume de chauffage (3) d'un circuit de puissance en un premier sous-volume (3.1) et un second sous-volume (3.2). La paroi de séparation (5) comprend au moins une ouverture de paroi (6) qui permet un écoulement de gaz (H) entre les sous-volumes (3.1, 3.2), et l'ouverture de paroi (6) a une surface d'ouverture à action aérodynamique basée sur une différence de pression entre la pression dans le premier sous-volume (3.1) et la pression dans le second sous-volume (3,2).
