Abstract
A magnetic particle-type electromagnetic coupling apparatus is cooled by a plurality of heat pipes which are partially embedded in the outer periphery of a rotating coupling member near the portion of the coupling member which is in contact with magnetic particles during operation. Heat is removed from the coupling member by a working fluid which is sealed within the heat pipes and is dissipated to the atmosphere through cooling fins attached to the heat pipes.
