Abstract
Abstract A modular cooling apparatus for computer systems is disclosed. The apparatus includes an air-guiding duct, a fan coupling to the duct and a coupling apparatus for coupling the air-guiding duct and the fan to an electronics housing. The air-guiding duct has an input opening to the exterior of the electronics housing and guides ambient outside air to the input of the fan. Then the fan directs this outside air to the inside of the electronics housing. The electronic housing can be formed between a base module and the computer system circuit board or between the air-guiding duct, fan and a retention module. Furthermore, outside air is delivered in a substantially perpendicular direction relative to the plane of the computer system circuit board within the electronics housing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
141 words
A cooling apparatus comprising: a. a modular fan with a rectangular casing; b. a modular air-guiding duct detachably coupled to said rectangular casing of said fan, said air-guiding duct including a first input opening to receive fresh air, said air-guiding duct including an enclosed channel to guide said fresh air from said first input opening to an input side of said fan; and c. a modular base with a second input opening, wherein the perimeter of said second input opening is at least the perimeter of said rectangular casing of said fan, to detachably couple said rectangular casing of said fan and said air-guiding duct over electronic components on a computer system circuit board in an orientation where said fan delivers said fresh air through said second input opening directly and unrestrictedly to said electronic components in a substantially perpendicular direction.
Claim 2
Dependent Claim
141 words
