Abstract
Abstract A cooling system for use with an engine and an associated engine driven flywheel. The system includes: centrifugal blower means fitted to and rotatable with the flywheel for developing a pressure differential thereacross; a housing enclosing said flywheel and said blower means for defining an air passage having a housing inlet for communicating air to said blower means and an output for permitting the discharge of air therethrough; air cooled heat exchange means connected to and positioned relative to the housing to permit air to flow therethrough by virtue of the operation of the blower means; damper means responsive to at least one engine operating parameter, for controlling the air flow through the heat exchange means; and compartment means for enclosing the blower means and housing and oriented to prohibit the entrance of ram air thereto and including inlet means for receiving non-ram air. Air conditioning condensers are positioned in communication with the compartment means and inlet means and cooled by the induced air provided by the operation of the blower means.
