Motor cooling device

A heating system for a vehicle comprising:

• a blower assembly including:
• an electric motor,
• a sealed motor housing for enclosing the electric motor,
• a drive shaft operably coupled to the electric motor and extending outwardly from the sealed motor housing, and
• a blower operably connected to the drive shaft;
• a heater for housing a heat exchanger, the blower assembly being mounted to an inlet end section of the heater;
• and
• a static motor cooling device mounted over the sealed motor housing and passively directing air being drawn into the blower assembly over the motor housing for decreasing an operating temperature of the electric motor with minimal effect on power consumption and air output of the heating system.

An airflow system for a vehicle comprising:

• a blower assembly including:
• an electric motor,
• a motor housing for enclosing the electric motor,
• a drive shaft operably coupled to the electric motor and extending outwardly from the motor housing, and
• a blower wheel operably connected to the drive shaft;
• and
• means for passively directing air being drawn into the blower assembly over the motor housing for decreasing an operating temperature of the electric motor, wherein the means for directing has minimal effect on power consumption and air output of the heating system.
