Abstract
Heat shield assemblies are normally connected to engines which have exhaust systems in order to reduce the temperature of the outer surface. The skin temperature of the outer surface of the heat shield assembly must be cooled so that persons coming in contact with such a surface is not burned. The subject heat shield assembly includes a heat source, an inner member and an outer member which respectively define first and second cooling flow paths. The first cooling flow path being adapted to convect heat away from the heat source and the inner member as air passes therethrough and the second cooling flow path being adapted to convect heat away from the inner member and the outer member as air passes therethrough. The air passing through the first and second cooling flow paths effectively reduces the temperature of the outer member so that no one would be burned upon contact therewith.
