Abstract
A fan assembly and associated methods are shown. Fan assemblies and methods include a fluid passage region defined between a fan motor and an outer housing. Example assemblies and methods include a number of hollow vanes located within the fluid passage region to permit an air flow between the fan motor and air external to the outer housing. In selected examples, fan motor cooling is facilitated using configurations described.

A fan assembly, comprising:
- a conduit defined by an outer housing;
- a fan motor located within the outer housing;
- a first impeller coupled to the fan motor to drive a first amount of air through a fluid passage region defined between the fan motor and the outer housing;
- a first set of inlet hollow vanes located within the fluid passage region to permit a second amount of air flow from external to the outer housing into the fan motor;
- and
- a second set of outlet hollow vanes located within the fluid passage region to permit the second amount of air flow from the fan motor back through the fluid passage, separated from the first amount of air.
