Fan shroud structure reinforcement to reduce or eliminate warping and distortion

A fan shroud structure ( 10 ) is constructed and arranged to carry a fan and motor. The fan shroud structure includes a base ( 12 ) and an annular rim ( 24 ) extending from the base. The rim defines a generally central opening ( 26 ) sized to accommodate blades of a fan. Motor mounting structure ( 2...

Zusammenfassung:	A fan shroud structure ( 10 ) is constructed and arranged to carry a fan and motor. The fan shroud structure includes a base ( 12 ) and an annular rim ( 24 ) extending from the base. The rim defines a generally central opening ( 26 ) sized to accommodate blades of a fan. Motor mounting structure ( 28 ) is coupled with the rim ( 24 ) and is disposed generally adjacent to the central opening ( 26 ). The motor mounting structure ( 28 ) is constructed and arranged to support a motor for driving a fan. The fan shroud structure ( 10 ) includes a first pair of opposing sides ( 14, 16 ) and a second pair of opposing sides ( 17, 18 ) coupled to the base to form a box-like configuration defining a perimeter of the fan shroud structure raised with respect to the base such that the sides are discontinuous with respect to the base ( 12 ) to shift resonance of the shroud structure.
