Abstract
A cooling system for an automotive propulsion system is provided. The cooling system includes a housing defining a housing inlet and a housing outlet. An exhaust pipe may be configured to be fluidly connected to an automotive engine, the exhaust pipe and defining a passageway for exhausting exhaust gases originating with the automotive engine. The housing outlet is connected in fluid communication with the passageway of the exhaust pipe, which may be through a cooling conduit. The exhaust pipe is configured to suck air from the housing outlet into the exhaust pipe to define a cooling air flow path from the housing inlet to the passageway of the exhaust pipe. In one variation, the outlet of the cooling conduit has an open end placed in a slipstream of the vehicle rather than in the exhaust pipe.
