US Patent 7207502 Velocity profile modifying device for nozzles

A velocity-profile modifying device is located between a heat component and an air pouring apparatus. The air pouring apparatus pours the air into the heat component via an air moving track. The velocity-profile modifying device is set at the air moving track and is used for modifying a first velocity-profile of airflow by the air pouring apparatus to a second velocity-profile and further for making the air distribute evenly toward the heat component. By providing the velocity profile modifying device, a better distribution of the airflow toward the heat component and a stable temperature status of the heat component can be achieved.
