Abstract
Cooling apparatus for transferring heat from and cooling one or more heat generating components that support or drive a flywheel or other spinning member. The apparatus may include a first heat transfer element attached to and spinning with the spinning member, a second heat transfer element stationary with respect to the spinning member, wherein the first and second heat transfer elements move relative to one another, and wherein the first and second heat transfer elements are shaped and positioned in close proximity to one another so that substantial heat is transferred from the first heat transfer element to the second heat transfer element. Alternatively, the apparatus may include a set of rotating vanes mounted to rotate with the spinning member, an orifice configured to direct a spray of cooling liquid onto the rotating vanes, wherein the cooling liquid is sprayed onto the rotating vanes at a radially inward location, so that the liquid flows radially outward over the surface of the vanes as a thin film of liquid, and is thrown off the vanes by centrifugal action, and collecting apparatus configured to collect the liquid thrown off of the vanes.
