Abstract
A cooling device for components of wind turbines, comprising at least one conduit (3) containing therein a working fluid (5) selected to change from a liquid to gas phase, and vice versa, during operation; wherein a first lower portion of each conduit (3) is inserted into a receptacle (2) through which a primary coolant fluid (10) transporting heat from a component of a wind turbine to be cooled (7) circulates, said lower portion acting as an evaporator of the working fluid (5); and wherein a second upper portion of each conduit (3) remains outside the receptacle (2), acting as a condenser of the working fluid (5).
Claims21
A cooling device for components of wind turbines, comprising a plurality of conduits, each conduit containing therein a working fluid selected to change from a liquid to gas phase, and vice versa, during operation;
- wherein a first lower portion of each conduit is inserted into a receptacle through which a primary coolant fluid transporting heat from a component of a wind turbine to be cooled circulates, said lower portion acting as an evaporator of the working fluid;
- and wherein a second upper portion of each conduit remains outside the receptacle, acting as a condenser of the working fluid;
- wherein:
- each conduit is sealed at both ends;
- and
- the plurality of conduits includes a first conduit holding a first working fluid and a second conduit holding a second working fluid, wherein the first and second working fluids have different boiling points.
