Title (EN) COIL DEVICE
(FR) DISPOSITIF DE BOBINES
(DE) SPULENVORRICHTUNG
Abstract:
(EN) The invention relates to a coil device (1) for a power converter, comprising a cooling plate (2) and a plurality N ≥ 3 of coil windings (4), wherein the cooling plate (2) is thermally coupled with at least one end face (400) of one of the coil windings (4). According to the invention, the coil windings (4) are arranged spatially offset to one another by an angle (41) of 2π/Ν , and the cooling plate (2) has a cooling channel (24), which at least partially extends around each of the N coil windings.
(FR) La présente invention concerne un dispositif de bobines (1) pour un convertisseur de courant. Ledit dispositif de bobines comporte une plaque de refroidissement (2) et une pluralité N ≥ 3 d’enroulements de bobine (4), la plaque de refroidissement (2) étant couplée thermiquement au moins par une face frontale (400) à un des enroulements de bobine (4). Selon l’invention, les enroulements de bobine (4) sont disposés dans l’espace décalés les uns par rapport aux autres selon un angle (41) de 2π/Ν et la plaque de refroidissement (2) comprend un canal de refroidissement (24) qui s’étend au moins en partie autour de chacun des N enroulements de bobine (4).
(DE) Es wird eine Spulenvorrichtung (1) für einen Stromrichter vorgeschlagen, die eine Kühlplatte (2) und eine Mehrzahl N ≥ 3 von Spulenwicklungen (4) umfasst, wobei die Kühlplatte (2) mit wenigstens einer Stirnseite (400) einer der Spulenwicklungen (4) thermisch gekoppelt ist. Erfindungsgemäß sind die Spulenwicklungen (4) räumlich um einen Winkel (41) von 2π/Ν versetzt zueinander angeordnet, und die Kühlplatte (2) weist einen Kühlkanal (24) auf, der sich wenigstens teilweise um jede der N Spulenwicklungen (4) erstreckt.
