Definitions
- Fig. 1 shows the principle of a simple, single-phase choke.
- a throttle 10 consists of a core sheet package 1 with two legs 2, 2 'and 2 yokes 3, 3'.
- the legs carry, for example, each 2 coils 4, 4 ', which are formed as single-layer disc coils, directly in between is a specially designed, double-acting flat cooler 5.
- the Einlagnier the disc coil causes each turn of the winding directly with a cooling surface in combination stands.
- a double-sided cooler can thus always cool 2 disc coils per leg, which has proven to be particularly advantageous.
- the insulating material used has a high insulation strength with sufficient thermal conductivity and mechanical pressure resistance. To equalize the contact pressure of the coils on the cooling surfaces latter with a special, relative soft, heat-conducting plastic film occupied, which also has a thickness of a few tenths of mm.
- the executed throttle shows as a result of the cooling measures taken both a weight reduction, as well as a volume reduction by about a factor of 2.5 compared to a forced air-cooled throttle equal construction capacity and conventional design with tubular layer winding. It is basically possible to apply the cooling arrangement according to the invention to other electromagnetic components, such as ironless chokes and transformers in general, and in particular to medium frequency transformers.

Claims (11)
- Composant électromagnétique refroidi par liquide, notamment inductance ou transformateur, constitué de plusieurs bobines en forme de disque avec une ou plusieurs spires et des refroidisseurs plats situés entre celles-ci, au moins 2 bobines en disques (4, 4') étant associées à un refroidisseur plat (5), chaque bobine en disque comportant des éléments d'enroulement sous la forme de spires de la bobine, dont chacune se trouve en contact thermique direct par l'intermédiaire d'une couche isolante conductrice de chaleur avec les surfaces du refroidisseur plat, pour le refroidissement étant prévu un milieu réfrigérant qui est séparé en potentiel par la couche isolante de l'élément d'enroulement et en tant que refroidisseur plat (5) étant utilisée une construction métallique multicouches avec structure réfrigérante interne et isolation en matière plastique externe, ladite couche de matière plastique entourant totalement le refroidisseur, caractérisé en ce que la construction métallique est constituée d'acier inoxydable non magnétique.
- Composant selon la revendication 1, caractérisé en ce que la matière plastique contient un remplissage qui améliore la conductance thermique.
- Composant selon l'une quelconque des revendications 1 ou 2, caractérisé en ce que pour améliorer le transfert thermique entre le disque de la bobine (bobine en disque) et la surface adjacente du refroidisseur plat, on utilise un film en matière plastique conducteur thermique de faible dureté et doté de propriétés élastiques ou flexibles, d'une épaisseur de quelques dixièmes de mm.
- Composant selon l'une quelconque des revendications 1 à 3, caractérisé en ce que les bobines en disques (4, 4') d'un ensemble d'enroulement sont forcées par un ensemble de pressage (6) mécanique en contact étroit avec les surfaces du refroidisseur plat (5).
- Composant selon l'une quelconque des revendications 1 à 4, caractérisé en ce que les bobines en disques (4, 4') se présentent en étant directement collées de manière thermo-conductrice sur la surface du refroidisseur.
- Composant selon l'une quelconque des revendications 1 à 5, caractérisé en ce que les bobines en disques (4, 4') d'une phase ou d'une pile de structure sont enroulées de sorte à éviter des liaisons extérieures, situées dans la région du refroidisseur plat et que les liaisons sérielles internes (13) s'adaptent dans les évidements prévus à cet effet d'une plaque de refroidisseur associée.
- Composant selon l'une quelconque des revendications 1 à 6, caractérisé en ce qu'un induit (3) est entouré de plaques métalliques (14, 14'), de préférence de plaques d'aluminium qui comportent des tubes métalliques (16), de préférence des tubes d'aluminium soudés sur leur extrémité et en ce qu'à travers les tubes métalliques, on fait passer le même milieu réfrigérant ou un milieu réfrigérant différent, ce qui donne lieu à un refroidissement efficient du cuivre et du fer.
- Composant selon la revendication 7, caractérisé en ce que le milieu réfrigérant traverse d'abord le refroidisseur plat (5) et ensuite seulement les tubes métalliques (16).
- Utilisation du composant selon l'une quelconque des revendications 1 à 8 dans des dispositifs convertisseurs de courant refroidis par eau.
- Utilisation du composant selon l'une quelconque des revendications 1 à 8 dans des dispositifs à moyenne fréquence, notamment pour l'échauffement par induction.
- Procédé destiné à fabriquer le composant selon l'une quelconque des revendications 1 à 8, caractérisé en ce qu'on colle le refroidisseur plat (5) de manière à ce qu'il soit conducteur thermique avec la bobine en disque (4) et en ce qu'on créé ainsi une unité modulaire.
