  • Electric motor driven blower assembly with integral motor cooling duct
    Patent number: 7118355
    Abstract: An electric motor driven blower assembly provides for a complete air cooling duct running from the inside of the blower housing to the motor at the back of the housing. A vertical cooling tube on the scroll housing is mated to an open, moldable trough in the motor cover across a sealing projection on a vibration gasket. The seal of the vertical tube through the gasket provides a right angle turn in the cooling duct, providing a complete cooling duct while still allowing all parts to be easily molded.
