<p>A cooling device comprising a rotating part (1) provided with an internal space (3) intended for the transport of cooling liquid and provided with external fins (4) intended for the transport of gas along at least a section of the rotating part. The rotating part is symmetrical in rotation and revolves around an axis of rotation (2) . The rotating part comprises a cooling liquid pump section (5) , a fan section (6) , and between these an intermediate section (7) arranged around the axis of rotation, where the fan section has a basic shape of a radially extended plate (15) , wherein the flow of cooling liquid enters at the pump section from an object to be cooled, proceeds through the intermediate section and turns back in the vicinity of the periphery (17) of the fan section, in order to once again pass the intermediate section and then be pumped back to the object by means of the pump section.</p> |
