Abstract
Abstract A fan device for an integrated circuit includes a finned plate, a fan having a rotor shaft, and a board member mounted to the finned plate. The finned plate includes a plurality of rows and columns of fins extending upwardly from an upper side thereof and a space defined in a center of the upper side, each two adjacent fins having a gap defined therebetween. The board member includes a hole defined in a mediate portion thereof, a support member provided in the hole, and a plurality of ribs extending downwardly from a periphery defining the hole to the support member, the support member including a stud formed on an upper side thereof and having a second hole defined therein for rotatably receiving the rotor shaft of the fan.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
A fan device for an integrated circuit comprising: a finned plate including a plurality of rows and columns of fins extending upwardly from an upper side thereof and a space defined in a center of the upper side, each two adjacent fins having a gap defined therebetween; a fan having a rotor shaft; and a board member securely mounted to the finned plate and including a hole defined in a mediate portion thereof, a support member provided in the hole, and a plurality of ribs extending downwardly from a periphery defining the hole to the support member, the support member including a stud formed on an upper side thereof and having a second hole defined therein for rotatably receiving the rotor shaft of the fan.
Claim 2
Dependent Claim

A fan device for an integrated circuit comprising: a finned plate including a plurality of rows and columns of fins extending upwardly from an upper side thereof and a space defined in a center of the upper side, each two adjacent fins having a gap defined therebetween; a fan having a rotor shaft; and a board member securely mounted to the finned plate and including a hole defined in a mediate portion thereof, a support member provided in the hole, and a plurality of ribs extending downwardly from a periphery defining the hole to the support member, the support member including a stud formed on an upper side thereof and having a second hole defined therein for rotatably receiving the rotor shaft of the fan.
Claim 3
Dependent Claim
47 words
The fan device as claimed in claim 1, wherein the board member further includes a plurality of protrusions extending outwardly from at least one side thereof, each protrusion being fittingly received in an associated said gap and thus being securely held between two associated adjacent said fins.
Claim 4
Dependent Claim
47 words
The fan device as claimed in claim 1, wherein the board member further includes a plurality of resilient legs extending downwardly and outwardly from an underside thereof, each leg being fittingly received in an associated gap and thus being securely held between two associated adjacent said fins.
Claim 5
Dependent Claim
47 words
The fan device as claimed in claim 2, wherein the board member further includes a plurality of resilient legs extending downwardly and outwardly from an underside thereof, each leg being fittingly received in an associated gap and thus being securely held between two associated adjacent said fins.
Claim 6
Dependent Claim
29 words
The fan device as claimed in claim 1, wherein the board member includes a plurality of third holes defined therein and is secured to the finned plate by fasteners.
Claim 7
Dependent Claim
29 words
The fan device as claimed in claim 2, wherein the board member includes a plurality of third holes defined therein and is secured to the finned plate by fasteners.
Claim 8
Dependent Claim
29 words
The fan device as claimed in claim 3, wherein the board member includes a plurality of third holes defined therein and is secured to the finned plate by fasteners.
Claim 9
Dependent Claim
29 words
The fan device as claimed in claim 4, wherein the board member includes a plurality of third holes defined therein and is secured to the finned plate by fasteners.
