Cooling by suction of air
First Claim
1. A cooling system for an automotive transmission of a motor vehicle, the cooling system comprising:
- a transmission housing defining a housing inlet and a housing outlet, the housing inlet being open to a surrounding environment without further connection;
a cooling conduit extending from the transmission housing, the cooling conduit defining a channel in fluid communication with the housing outlet, the cooling conduit having an open end, the open end being disposed in a main flow path of air such that the cooling conduit is configured to suck air from the housing outlet into the main flow path to define a cooling air flow path from the housing inlet, through the housing, out of the housing outlet, through the cooling conduit, and out of the open end.

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.
