Claims (7)
1. Generator (1), især til en vindmølle, omfattende en udvendig rotor (2) med et antal af permanente magneter (3), der er anbragt i en omkredsretning, og en indvendig stator (4) med en statorlaminering (5) og et kølemiddel, hvor statoren (4) er forsynet med et væskekølemiddel, kendetegnet ved, at statorlamineringen (5) er inddelt i to dele, hvorimellem der er tilvejebragt en central luftkanal (9), som rummer kølerør (10, 21, 22) af væskekø lemidlet, hvor kølerørene (10, 21, 22) strækker sig i statorlamineringen (5) fra den centrale luftkanal (9) til statorfingerpladerne (12), som begrænser dem i siden, og hvor der er anbragt en indløbs- og udløbsdel af kølerørene i den centrale luftkanal (9), hvorfra de strækker sig radialt med henblik på at blive forbundet med et centralt indløb (17) og med et centralt udløb (18) af væskekø-lemidlet.
2. Generator ifølge krav 1, kendetegnet ved, at kølerørene (10, 21) er anbragt skiftevis i den centrale luftkanal (9), således at et kølerør, som strækker sig fra den centrale luftkanal til den venstre side af statoren, er anbragt ved siden af et kølerør, som strækker sig til den højre side af statoren.
3. Generator ifølge krav 1 eller 2, kendetegnet ved, at kølerørene (10, 21) er anbragt forskudt, således at kølerørene (10, 21), som strækker sig til den venstre side af statoren, og kølerørene (10, 21), som strækker sig til den højre side af statoren, overlapper aksialt hinanden i luftkanalen (9).
4. Generator ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at et kølerør (10, 21, 22) omfatter et indløbskredsløb og et udløbskredsløb.
5. Generator ifølge krav 4, kendetegnet ved, at et kølerør (10, 21, 22) er et ekstruderet rør.
6. Generator ifølge krav 4 eller 5, kendetegnet ved, at et kølerør (10, 21,22) omfatter en indvendig væg (13, 23), der adskiller indløbskredsløbet og udløbskredsløbet.
7. Vindmølle, omfattende en generator ifølge et hvilket som helst af kravene 1 til 6.
