Self-cooling system for an enclosed housing

A self-cooling system, comprising:

• a first rotating component coupled to a second rotating component, via a coupling, wherein the first rotating component is configured to drive rotation of the second rotating component;
• and
• a housing configured to enclose the first rotating component, the second rotating component, and the coupling, wherein the first rotating component, the second rotating component, and the coupling are configured to rotate relative to the housing, and the housing comprises:
• at least one inlet bore;
• and
• at least one exhaust bore, wherein the at least one exhaust bore is disposed radially outward from a radial position of the at least one inlet bore with respect to an axis of rotation of the first rotating component, and wherein the at least one inlet bore and the at least one exhaust bore are positioned to establish a pressure differential to circulate a fluid into the at least one inlet bore, through the housing, and out of the at least one exhaust bore;
• wherein the self-cooling system does not comprise a dedicated fan or additional rotating component configured to drive the fluid into the at least one inlet bore, through the housing, and out of the at least one exhaust bore;
• and
• wherein the at least one inlet bore and the at least one exhaust bore are disposed in an axial end of the housing with respect to the axis of rotation, and the at least one inlet bore and the at least one exhaust bore extend from an exterior of the housing to an interior of the housing.
