Abstract
(DE)
Die Erfindung betrifft einen Schaltschrank (1) mit: - einem Schaltschrankgehäuse (2), das elektrische Leistungszugänge, Leistungsabgänge und Kühlungsanschlüsse aufweist, die nach außen führen, - zumindest einem wärmeerzeugenden Bauelement, wobei ein Bauelement über ein flüssigkeitsdurchströmtes Kühlelement (11) kühlbar ist, wobei das Kühlelement (11) zumindest an der dem Bauelement abgewandten Seite Kühlrippen (9) aufweist, - zumindest zwei Kühlkreisläufen, wobei ein erster Kühlkreislauf ein flüssigkeitsdurchströmtes Kühlelement (11) aufweist und ein zweiter Kühlkreislauf ein innerhalb des Schaltschrankes (1) geschlossener Kreislauf eines gasförmigen Mediums ist.
(EN)
The invention relates to a control cabinet (1) comprising: a control cabinet housing (2) having electrical power inlets, power outlets and cooling connections, which lead outwards; at least one heat-generating component, wherein a component can be cooled via a cooling element (11) through which a fluid flows, wherein the cooling element (11) has cooling ribs (9) at least on the side facing away from the component; and at least two cooling circuits, wherein a first cooling circuit has a cooling element (11) through which a fluid flows and a second cooling circuit is a circuit for a gaseous medium that is closed within the control cabinet (1).
(FR)
La présente invention concerne une armoire électrique (1) ayant : - un corps d'armoire électrique (2) qui comprend des entrées de puissance électrique, des sorties de puissance électrique et des branchements de refroidissement, qui sortent de l'armoire; - au moins un composant générateur de chaleur, un composant pouvant être refroidi par un élément de refroidissement (11) parcouru par un fluide, l'élément de refroidissement (11) comprenant au moins des nervures de refroidissement (9) sur le côté opposé au composant; - au moins deux circuits de refroidissement, un premier circuit de refroidissement comprenant un élément de refroidissement (11) parcouru par un fluide et un second circuit de refroidissement étant un circuit de refroidissement, fermé et interne à l'armoire électrique (1), d'un agent gazéiforme.
