RADIAL BLOWER AIR GUIDE, SYSTEM, AND METHOD OF COOLING

摘要

A radial blower air guide includes a first end wall substantially circumscribing an end bracket of an electric motor. The air guide includes a second end wall spaced apart from the first end wall and has an inner periphery that circumscribes a periphery of the motor. The air guide includes an outer wall extending from an edge of the first end wall to an edge of the second end wall. The outer wall is formed from a thin curved plate and partially defines a ring-shaped chamber therebetween. The outer wall has an aperture defined therethrough. The air guide includes a baffle plate coupled to the inner periphery of the second end wall. The baffle plate extends a first width toward the first end wall and partially defines the chamber. The baffle plate is configured to deflect air to control the distribution of the airflow from the chamber.

主权项

1. An air guide for use with an electric motor having a central longitudinal axis, said air guide comprising:
a first end wall substantially circumscribing an end bracket of the electric motor; a second end wall spaced apart from said first end wall, said second end wall having an inner periphery that substantially circumscribes a periphery of the electric motor; an outer wall extending from an edge of said first end wall about at least a portion of the circumference thereof, said outer wall extending to an edge of said second end wall, said outer wall being formed from a thin curved plate and at least partially defining a ring-shaped chamber between said first end wall and said second end wall, said outer wall having an aperture defined therethrough; and a baffle plate coupled to said inner periphery of said second end wall, said baffle plate extending a first width toward said first end wall and at least partially defining said ring-shaped chamber, said baffle plate configured to deflect an airflow entering through said aperture to control a distribution of said airflow from said ring-shaped chamber.
