ABSTRACT:
In order to provide improved cooling for electrical machinery, especially A. C. generators for motor vehicles, with elimination of a rotating ventilating fan, the invention provides heat pipes disposed so that the evaporation regions of the heat pipes contact or surround the heat-producing parts of the generator, in particular the stator windings and the rectifying diodes. These regions communicate through sealed conduits with condensation regions that are located in places subject to lower temperatures that prevail near the heat producing elements. Disposed within the heat pipes are per se known capillary structures which transport condensed heat transport medium back to the evaporation region. Various embodiments are presented.
