Abstract
A totally enclosed fan cooled (TEFC) induction motor or other type of induction motor auxiliary cooling system has a buffet thermal shroud that is oriented in opposed spaced relationship over existing motor housing cooling fins. An airflow channel is defined between the motor cooling fins and the shroud, for direction and passage of a cooling airflow. Tabs are oriented in the airflow channel between opposed cooling fins where they are in thermal and fluid communication with the cooling air flow. In some embodiments the tabs are shroud fingers that project inwardly from the shroud. The tabs or shroud fingers create turbulence in the cooling air flow that increases convective heat transfer efficiency and contact time between the cooling air and motor cooling fins. Tabs or shroud fingers also absorb heat from the cooling air flow. Shroud fingers also transfer that absorbed heat conductively to the shroud.
