High efficiency fluid mover

A fluid mover comprising:

• a rotor to transfer momentum with a fluid when operated at a given volumetric flow rate through the rotor, the rotor including a plurality of enclosed passages to transfer momentum in or out of the fluid as the fluid passes through the enclosed passages in response to rotation of the rotor, wherein the passages are formed with a cross sectional shape and cross sectional dimensions along their entire length sufficient to establish and maintain laminar flow of the fluid along the entire length of the enclosed passages when the fluid is passing through the rotor at the given volumetric flow rate;
• and
• a motor to include a stator assembly to drive the rotor in a rotational motion around an axis.

A system comprising:

• a computing platform including a heat generating component;
• and
• a cooling fan to cool the heat generating component, the cooling fan to include a rotor to transfer momentum with a fluid when operated at a given volumetric flow rate through the rotor, the rotor including a plurality of enclosed passages to transfer momentum in or out of the fluid as the fluid passes through the enclosed passages in response to rotation of the rotor, wherein the passages are formed with a cross sectional shape and cross sectional dimensions along their entire length sufficient to establish and maintain laminar flow of the fluid along the entire length of the enclosed passages when the fluid is passing through the rotor at the given volumetric flow rate.
