Description

7910145-7 egenskaperna. - ' A J! Föreliggande uppfinning har till ändamål att vidareutveckla spolen enligt DOS 26 58 744 så att den i litsledarna uppkommande strömvärmen kan avledas ännu bättre- Denna uppgift löses genom att med lindningen ett av kylnedium genomströmbart rör medlindas, vilket har en tillplattad profil, har kontakt med lindningen och består av ett omagnetiskt, elek- triskt isolerande material. 7910145-7 properties. - 'A J! The object of the present invention is to further develop the coil according to DOS 26 58 744 so that the current heat generated in the line conductors can be dissipated even better. This problem is solved by co-winding a tube through which cooling material can flow, which has a flattened profile, has contact with the winding and consists of a non-magnetic, electrically insulating material.

Därmed uppnås fördelarna att det i lindningen uppkommande värmet kan avledas ännu bättre, emedan vätskekylning är möjlig, i stället för den hittills använda luftkylningen. För kylningen kan dessutom icke blott isolerande vätskor användas utan även vatten, emedan kylvätskan icke har någon kontakt med lindningen.This achieves the advantages that the heat generated in the winding can be dissipated even better, because liquid cooling is possible, instead of the air cooling used so far. In addition, not only insulating liquids can be used for cooling, but also water, since the coolant has no contact with the winding.

Emedan kylprofilen består av ett elektriskt isolerande och omag- netiskt material induceras inga virvelströmmar i detta och så- lunda alstras inga ytterligare förluster. Litsledarna består av så klena trådar som möjligt med cirka 0,1 mm diameter och smyger sig sålunda mycket väl an till kylprofilen, så att en god termisk kontakt uppnås. Genom att litsen i förhållande till sin tjocklek kan pressas ganska bred är värmebanan i litsen kort och den _ värmeöverförande ytan är mycket stor. Spolen enligt uppfinningen kan sålunda belastas väsentligt mer än spolen enligt DOS 26'58-744, även om denna redan kan belastas mycket starkt.Since the cooling profile consists of an electrically insulating and non-magnetic material, no eddy currents are induced in this and thus no further losses are generated. The line conductors consist of as small wires as possible with a diameter of about 0.1 mm and thus sneak very well to the cooling profile, so that a good thermal contact is achieved. Because the lits can be pressed quite wide in relation to their thickness, the heat path in the lits is short and the heat-transferring surface is very large. The coil according to the invention can thus be loaded significantly more than the coil according to DOS 26'58-744, even though this can already be loaded very strongly.

Företrädesvis har kylröret en fyrkantprofil, varvid de långa sidorna antingen kan formas plana, bikonkava eller bikonvexa.Preferably, the cooling tube has a square profile, the long sides being able to be formed either flat, biconvex or biconvex.

Den ifrågakommande formen av kylprofilen väljs motsvarande kraven på lindningen. Företrädesvis är kylrörets väggtjocklek tunn och röret är utformat såsom flerkammarrör med inre stödflänsar. Där- igenom förblir det termiska motståndet mellan lindning och kyl- medium lågt och trots detta föreligger ingen risk för att kyl- röret under lindningens dragkraft skall sammanpressas.The relevant shape of the cooling profile is selected corresponding to the requirements of the winding. Preferably, the wall thickness of the cooling pipe is thin and the pipe is designed as a multi-chamber pipe with internal support flanges. As a result, the thermal resistance between winding and cooling medium remains low and despite this there is no risk that the cooling pipe will be compressed under the traction of the winding.

Företrädesvis består röret av ett termiskt stabilt, termoplast- 4 nr material. Dylikt plastmaterial är tillräckligt böjligt för att kunna upplindas tillsammans med lindningen. 7910145-7 Företrädesvis vakuumgjuts den färdiglindade spolen med ett gjut- harts. Därigenom alstras en god termisk kontakt, både mellan lits- trådarna sinsemellan och med kylprofilen.Preferably, the tube consists of a thermally stable, thermoplastic material. Such a plastic material is flexible enough to be wound up together with the winding. 7910145-7 Preferably vacuum cast the pre-wound coil with a casting resin. This creates a good thermal contact, both between the twine threads among themselves and with the cooling profile.

I anslutning till bifogade ritning förklaras uppfinningen närmare i form av ett utföringsexempel.In connection with the accompanying drawing, the invention is explained in more detail in the form of an exemplary embodiment.

På ritningen visar-fig. l en spole i bild uppifrån, skuren enligt linjen I-I i fig. 2¿ samt fig. 2 spolen i sidovy, delvis skuren längs linjen II-II i fig. l.In the drawing, FIG. 1 a coil in the view from above, cut along the line I-I in Fig. 2¿ and Fig. 2 the coil in side view, partly cut along the line II-II in Fig. 1.

På ritningen visas en högflexibel, flätad lits l med pålödda elektriska anslutningsdon 2, 3, som är lindad tillsammans med ett kylrör 4. Det av en högtemperaturbeständig termoplast fram- ställda röret 4 har en tunn yttervägg 5, för att det termiska motståndet skall förbli lågt. För att röret 4 icke skall hop- pressas genom lindningsdragkraften är det förstyvat med invänd- igt belägna flänsar 6. Därigenom erhåller röret 4 ett flertal kammare. Såsom anslutningar för tillförsel av kylvätskan finns slangstutsar 7, 8 av plast, vilka är påsvetsade vid kylrörets 4 ände 10. Spolen kringgjöts efter lindningen av lindningen 1 och kylröret 4 i en form med gjutharts 9. Detta sker under vakuum för att en god termisk kontakt skall ske både mellan litstrådarna sinsemellan och med kylprofilen.The drawing shows a highly flexible, braided lits 1 with soldered electrical connectors 2, 3, which are wound together with a cooling tube 4. The tube 4 made of a high-temperature-resistant thermoplastic has a thin outer wall 5, so that the thermal resistance remains low. . In order for the tube 4 not to be compressed by the winding traction force, it is stiffened with internally located flanges 6. Thereby, the tube 4 obtains a number of chambers. As connections for supplying the coolant, there are plastic hose connections 7, 8, which are welded at the end 10 of the cooling tube 4. The coil is cast after the winding of the winding 1 and the cooling tube 4 in a mold with casting resin 9. This is done under vacuum to make a good thermal contact shall take place both between the lit threads among themselves and with the cooling profile.
