An arrangement with a nacelle and a radiator of a wind turbine is provided. The nacelle is rotatable connected with the radiator. Thus, a joint component of the wind turbine is built by these elements. The connection is constructed and arranged such that the radiator is allowed to pivot between a first position and a second position. The radiator is locked in the first position and projects above the nacelle when the radiator is used to remove heat from the nacelle to the environment. When the radiator is locked in the second position the radiator is close to a side of the nacelle. Thus a minimum height of the joint component is achieved.
