ABSTRACT:
An electrical generator (80) utilizes supplemental blowers or fans (140) to move additional cooling fluid through coolant flow paths (116, 124) in the generator, thus reducing the internal temperature of the generator. The supplemental blower comprises a blower (160) for supplementing cooling fluid flow through a discharge coolant flow path (155) and/or a supplemental blower (176, 178) for supplementing cooling fluid flow through an inlet coolant flow path (156). Either supplemental blower has the effect of lowering the peak internal generator temperature (134).
