Title
(DE) THERMISCHES VAKUUMDÄMMELEMENT
(EN) THERMAL VACUUM INSULATION ELEMENT
(FR) ÉLÉMENT D'ISOLATION THERMIQUE SOUS VIDE
Abstract
(DE) Thermisches Vakuumdämmelement (10), umfassend ein erstes flächiges Begrenzungsteil (12) und ein zweites flächiges Begrenzungsteil (14). Die Begrenzungsteile sind voneinander beabstandet und definieren zwischen sich einen vakuumierten Raum (16). Der vakuumierte Raum (16) ist durch Mittel (26) zum Abdichten abgedichtet. Das Vakuumdämmelement umfasst erste Stützelemente (18), die sich von dem ersten Begrenzungsteil (12) weg in den vakuumierten Raum (16) erstrecken und zweite Stützelemente (20), die sich von dem zweiten Begrenzungsteil (14) weg in den vakuumierten Raum (16) erstrecken, wobei die Begrenzungsteile (12, 14) mit den Stützelementen (18, 20) so angeordnet sind, dass die ersten Stützelemente (18) und die zweiten Stützelemente (20) aneinander vorbeiragen und voneinander beabstandet sind. Die ersten Stützelemente (18) sind von dem zweiten Begrenzungsteil (14) beabstandet, und die zweiten Stützelemente (20) sind von dem ersten Begrenzungsteil (12) beabstandet. Ein Fasergebilde (22) verbindet die ersten Stützelemente (18) und die zweiten Stützelemente (20) miteinander. Das Fasergebilde (22) weist eine geringe Wärmeleitfähigkeit auf und ist ausgestaltet, zumindest den durch das Vakuum auf das erste und das zweite Begrenzungsteil (12, 14) erzeugten Druck aufzufangen.
(EN) The invention relates to a thermal vacuum insulation element (10), comprising a first flat limiting part (12) and a second flat limiting part (14). The limiting parts are spaced apart from one another and define an evacuated space (16) between them. The evacuated space (16) is sealed by sealing means (26). The vacuum sealing element comprises first support elements (18) extending away from the first limiting part (12) into the evacuated space (16) and second support elements (20) extending away from the second limiting part (14) into the evacuated space (16), wherein the limiting parts (12, 14) are arranged with the support elements (18, 20) in such a way that the first support elements (18) and the second support elements (20) protrude beyond one another and are spaced apart from one another. The first support elements (18) are spaced apart from the second limiting part (14) and the second support elements (20) are spaced apart from the first limiting part (12). A fibre structure (22) connects the first support elements (18) and the second support elements (20) to one another. The fibre structure (22) has a low heat conductivity and is designed to collected at least the pressure generated by the vacuum on the first and the second limiting part (12, 14).
(FR) L'invention concerne un élément d'isolation thermique sous vide (10), comprenant une première partie de limitation plate (12) et une seconde partie de limitation plate (14). Les parties de limitation sont espacées l'une de l'autre et définissent un espace mis sous vide (16) entre elles. L'espace mis sous vide (16) est fermé de manière étanche par des moyens d'étanchéité (26). L'élément d'étanchéité sous vide comprend des premiers éléments de support (18) s'étendant à l'opposé de la première partie de limitation (12) dans l'espace mis sous vide (16) et des seconds éléments de support (20) s'étendant à l'opposé de la seconde partie de limitation (14) dans l'espace mis sous vide (16), les parties de limitation (12, 14) étant agencées avec les éléments de support (18, 20) de telle sorte que les premiers éléments de support (18) et les seconds éléments de support (20) font saillie au-delà les uns des autres et sont espacés les uns des autres. Les premiers éléments de support (18) sont espacés de la seconde partie de limitation (14) et les seconds éléments de support (20) sont espacés de la première partie de limitation (12). Une structure fibreuse (22) relie les premiers éléments de support (18) et les seconds éléments de support (20) les uns aux autres. La structure fibreuse (22) a une faible conductivité thermique et est conçue pour collecter au moins la pression générée par le vide sur la première et la seconde partie de limitation (12, 14).
