Abstract
The present invention discloses a cooling device for cooling a wind turbine generator system as well as the wind turbine generator system, wherein the cooling device comprises: a first cooling circuit used for sealing and cycling a first coolant and comprising a first inflow pipeline, one or more heat-absorbing units, a first outflow pipeline and a heat dissipation unit which are in fluid communication with each other in sequence, and the heat dissipation unit being connected to the first inflow pipeline and thus forming the first cooling circuit to be circulatory, and a second cooling circuit used for cooling the heat dissipation unit of the first cooling circuit, a second coolant being adopted by the second cooling circuit and taking away the heat in the heat dissipation unit, so that a first gaseous coolant in the heat dissipation unit is transformed into a first liquid coolant.
