摘要： A resistive grid enclosure for a vehicle having a dynamic braking capability, the grid enclosure defining an air inlet, an air outlet, and an airflow path through the enclosure from the air inlet to the air outlet. A resistive grid disposed within the enclosure is cooled by air flowing through the airflow path from the air inlet to the air outlet. The airflow path is configured so that an inlet airflow is heated by absorbing heat from the resistive grid and directed toward the air outlet forming a heated outlet airflow. The airflow path is further configured to direct at least a portion of the heated outlet airflow into the air inlet to reduce blockage of the air inlet by ice or snow.
