  • Patent number: 4331209
    Abstract: A ventilation system for electric vehicles in which a fan draws air into a housing surrounding the pump motor. A portion of the air entering the housing flows through ports in the pump motor to cool the motor before leaving the system through an exit port in the motor. The remainder of the air drawn into the housing flows through a duct and into a manifold from where a portion of the air flows through ports in the drive motor to cool the drive motor, a portion of the air flows through a duct to the pump motor S.C.R. control, and the remainder of the air flows through a duct and into the drive motor S.C.R. control, for cooling those units. A filter may be provided over the intake for the fan to prevent dust and other contaminants from reaching the motors and control mechanisms, thus minimizing the risk or fouling of the motors and controls.
