Abstract

A side-discharge blower fan unit with ductwork for controlling air flow is disclosed, according to certain embodiments.

First claim

We claim:

1 . A blower fan unit comprising:
a top surface; a bottom surface, wherein the bottom surface faces a motherboard when the blower fan unit is installed over the motherboard and the bottom surface includes an air intake; and a ductwork system comprising a set of fins arranged at an air discharge region of the blower fan unit, wherein the set of fins divide the air discharge region into at least three air ducts; wherein:
a first air duct of the at least three air ducts comprises a first inlet and a first outlet;
a second air duct of the at least three air ducts comprises a second inlet and a second outlet;
a third air duct of the at least three air ducts comprises a third inlet and a third outlet;
a inlet size ratio of the first inlet to the second inlet to the third inlet is in a first range of 1.0:1.35:2.7 to 1.0:1.65:3.3; and
an outlet size ratio of the first outlet to the second outlet to the third outlet is in a second range of 1.0:1.0:1.0 to 1.0:1.11:1.25.

2 . The blower fan unit of claim 1 , further comprises mounting holes for connecting to a plurality of struts of a mounting system to mount the blower fan unit to the motherboard such that the blower fan unit is located directly over the motherboard.

3 . The blower fan unit of claim 1 , further comprises an attachment system for attaching the blower fan unit to a radiator.

4 . The blower fan unit of claim 3 , wherein the radiator is associated with a closed loop liquid cooler for cooling a CPU or a GPU associated with the motherboard.

5 . The blower fan unit of claim 2 , wherein each strut of the plurality of struts has a length of substantially 45 millimeters to raise the blower fan unit over the motherboard.

6 . The blower fan unit of claim 2 , wherein each strut of the plurality of struts has a length in a range of 40 millimeters to 50 millimeters to raise the blower fan unit over the motherboard.

7 . The blower fan unit of claim 1 , further includes vibration dampers.
