    Patent number: 6283726
    Abstract: A radial blower, particularly for heating and air-conditioning systems for automobiles, has a spiral blower housing that is provided with an air intake (5) in a housing lateral wall and with an air outlet out of the spiral housing. A blower drive motor for a fan wheel is mounted to the housing with the fan wheel positioned in the spiral housing to face the air intake (5). The fan wheel has a fan ring with fan blades and a hub. The fan ring and the hub are connected to each other by a shell shaped vaulted or dished fan disk, which at least partly surrounds the drive motor. Fan disk openings (43) permit at least a portion of cooling air flowing through the drive motor to be discharged through the disk openings (43) into a blower air discharge chamber (23) in the spiral housing.
