Abstract
A compact, energy efficient air cooling system for a rotating shaft bearing module includes a Coanda surface having a periphery that smoothly curves from a radial center to axial alignment with a side of the module. A fan blade mounted on the shaft directs an airflow radially parallel and adjacent to the Coanda surface, causing the airflow to be bent by the Coanda effect from radial to axial, and to be directed along the side of the housing. Embodiments that can be applied to existing housings include a Coanda panel adjacent to the housing end face. A double suction fan blade can draw both external air and air from between the panel and the housing. In other embodiments the housing end face itself is a Coanda surface. A fan cover can have an inwardly curved periphery that forms a reduced gap or nozzle with the Coanda surface.
