CA 2373156

An offshore wind turbine is disclosed wherein the power transmission in the nacelle is cooled by means of a liquid conducted to the nacelle from the tower on which the nacelle is pivotally arranged around a vertical yawing axis. The liquid transfers heat to the seawater near the turbine which is used as a heat sink of low temperature and enormous heat capacity as compared to traditional air cooling. The liquid is conducted in a closed circuit and the cooling system may comprise more than one cooling circuit. The flow of cooling-liquid may be conducted between the tower and the nacelle through a heat transfer unit having a first part that is stationary with respect to the tower and a second part that is stationary with respect to the nacelle. The parts have at least one annular passageway for a liquid flow defined between abutting surfaces of the parts.

L'invention concerne une éolienne marine dans laquelle la transmission d'énergie dans la nacelle est refroidie par un liquide envoyé dans la nacelle à partir de la colonne sur laquelle la nacelle est montée pivotante autour d'un axe de lacet vertical. Le liquide transfère la chaleur dans l'eau de mer près de la turbine qui sert de puits de chaleur à température basse et possède une énorme capacité thermique en comparaison d'un refroidissement par air classique. Le liquide est envoyé dans un circuit fermé et le système de refroidissement peut comprendre plusieurs circuits de refroidissement. Le flux de liquide de refroidissement peut être envoyé entre la colonne et la nacelle par une unité de transmission de chaleur possédant une première partie fixe par rapport à la colonne et une deuxième partie fixe par rapport à la nacelle. Les parties possèdent au moins un passage annulaire d'un écoulement liquide défini entre les surfaces contiguës des parties.
