Abstract: A cooling system for cooling a plurality of electronic components comprises a centralized source comprising at least one micro cooler configured to deliver a flow of a cooling medium and a plurality of baffles configured to redistribute the cooling medium over the electronic components. The electronic components are situated in an enclosure.

Abstract: A pressurized air-cooled rotating electrical machine comprising a housing, and a rotor and stator disposed within the housing driven by a shaft is provided. The pressurized air-cooled rotating electrical machine also comprises a compressor operable to pressurize air within the housing to increase the volumetric heat capacity of the air within the housing. The rotating electrical machine may also have a temperature feedback device disposed within the housing to provide a signal representative of temperature within the housing. The pressurized air-cooled rotating electrical machine may also comprise a pressure sensor operable to detect air pressure within the housing. A controller may be coupled to the temperature feedback device and the compressor to regulate the air pressure inside the rotating electrical machine based on the temperature within the rotating electrical machine.
