First Claim
Patent Images
1. A cooling system for a wind turbine, said cooling system used to cool at least one component in said wind turbine, said cooling system comprising:
- a filter system comprising at least one primary filter and at least one secondary filter, said filter system including a switch to select between said at least one primary filter and said at least one secondary filter;
a cooling circuit comprised of at least one conduit and a coolant medium;
a pressure sensing system to sense the pressure differential between an input of the filter system and an output of the filter system, wherein a signal can be sent to the filter system when the pressure differential exceeds a predetermined threshold value, thereby indicating that the at least one primary filter is experiencing reduced flow; and
wherein said filter system switches from said at least one primary filter to said at least one secondary filter, the switch having a first configuration where the coolant medium is routed through the primary filter but not the secondary filter, and the switch having a second configuration where the coolant medium is routed through the secondary filter but not the primary filter.

Abstract
A cooling system and method is provided for a wind turbine. The cooling system is used to cool at least one component in the wind turbine, and includes a filter system having at least one primary filter and at least one secondary filter. A switch selects between the primary filter and the secondary filter. A cooling circuit includes at least one conduit and a coolant medium. The filter system can switch from the primary filter to the secondary filter.

10. A method for cooling at least one component in a wind turbine, said method comprising:
-
providing a filter system, said filter system comprising at least one primary filter and at least one secondary filter, said filter system including a switch to select between said at least one primary filter and said at least one secondary filter; providing a cooling circuit comprised of at least one conduit and a coolant medium; providing a pressure sensing system to sense the pressure differential between an input of said filter system and an output of said filter system; transmitting a signal to said filter system when said pressure differential exceeds a predetermined threshold value, thereby indicating that said at least one primary filter is experiencing reduced flow, and switching from said at least one primary filter to said at least one secondary filter. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A wind turbine having a cooling system used to cool at least one component in the wind turbine, the wind turbine comprising:
-
a tower; a nacelle; at least one component to be cooled housed within at least one of the tower and the nacelle; a filter system comprising a primary filter and a secondary filter, the filter system including a switch to select between the primary filter and the secondary filter; a cooling circuit comprised of at least one conduit and a coolant medium; wherein the filter system switches from the primary filter to the secondary filter, the switch having a first configuration where the coolant medium is routed through the primary filter but not the secondary filter, and the switch having a second configuration where the coolant medium is routed through the secondary filter but not the first filter. - View Dependent Claims (20)
