Blower fan with through hole and fan support rod

A blower fan for use in an information handling system thermal regulation system, comprising:

• a fan housing to house the fan having an outlet aperture on one side rotationally co-planar with a set of fan blades;
• the blower fan including:
• a power input;
• a cylindrical bearing including a cylindrical hollow receiving portion extending from a top of the cylindrical bearing to the bottom of the cylindrical bearing;
• a cylindrical main shaft rotatably inserted into the cylindrical hollow receiving portion of the cylindrical bearing;
• the cylindrical main shaft including a shaft pass-through hollow portion extending from a top of the cylindrical main shaft to the bottom of the cylindrical main shaft;
• and
• a set of fan blades mechanically coupled to the cylindrical main shaft;
• and
• a fan support rod passing through the cylindrical bearing and cylindrical main shaft at the shaft pass-through to support the fan within the housing to prevent deflection of a chassis of the information handling system into rotation of the fan blades;
• and
• a magnetic drive system to drive rotation of the set of fan blades.

An information handling system, comprising:

• a keyboard support chassis to mount the keyboard thereon including a C-cover to house the keyboard;
• and
• a processor, memory, and power source;
• a blower fan including:
• a cylindrical bearing including a cylindrical hollow receiving portion extending from a top of the cylindrical bearing to the bottom of the cylindrical bearing;
• a cylindrical main shaft rotatably coupled in the cylindrical hollow receiving portion of the cylindrical bearing;
• the cylindrical main shaft including a hollow portion extending from a top of the cylindrical main shaft to the bottom of the cylindrical main shaft;
• a set of fan blades mechanically coupled to the cylindrical main shaft;
• an electromagnetic motor to drive rotation of the set of fan blades;
• and
• a fan support rod passing through the cylindrical bearing and cylindrical main shaft and mechanically supporting the fan between the keyboard support chassis and a D-cover mechanically coupled to the D-cover to prevent deflection of the D-cover into rotation of the set of fan blades.
