Abstract

A fan device for dissipating heat from an electronic component includes a base having a number of upward extending fins. The fins on the side portions are higher than the middle fins. A board is secured above the shorter fins and engaged between the higher fins, and includes a number of orifices for air circulation purposes. The board includes a support engaged in an opening and coupled to the board for securing a fan. Alternatively, the board may be engaged on top of the higher fins, or, the fins may have identical height and include a depression formed in the middle portion for engagement with the fan.

Claims

1. A fan device for dissipating heat from an electronic component, said fan device comprising:

a base including two side portions having a plurality of first fins extending upward therefrom and including a middle portion having a plurality of second fins extending upward therefrom, said first fins being higher than said second fins;

a board member engaged above said second fins and between said first fins, said board member including a plurality of orifices formed therein for air circulation therethrough and including an opening formed therein, a support element engaged in said opening and coupled to said board member;

means for securing said board member to said second fins; and

,

a fan secured to said support element and located above said second fins for circulating air.

2. A fan device according to claim 1, wherein said board member further comprises at least two extensions extending downward therefrom, said extensions each including a hook means.

3. A fan device according to claim 1, wherein said board member further comprises a recess formed therein, wherein said opening communicates with said recess, said board member further comprising stud means extending inward of said recess for securing objects.

4. A fan device according to claim 1, wherein said support element includes a plurality of orifices formed therein for air circulation therethrough.

5. A fan device according to claim 1, wherein said board member further comprises four corner areas each having a hole formed therein for engagement with said securing means, said corner areas each having a thickness larger than that of the rest of said board member.

6. A fan device for dissipating heat from an electronic component, said fan device comprising:

a base including two side portions having a plurality of first fins extending upward therefrom and including a middle portion having a plurality of second fins extending upward therefrom, said first fins being higher than said second fins;

a board member engaged on top of said first fins and including a plurality of orifices formed therein for air circulation therethrough and including an opening formed therein, a support element engaged in said opening and coupled to said board member;

means for securing said board member to said first fins; and

,

a fan secured to said support element and located above said second fins for circulating air.

7. A fan device for dissipating heat from an electronic component, said fan device comprising:

a base including a plurality of fins extending upward therefrom and including a middle portion having a depression formed therein;

a board member engaged on top of said fins and including a plurality of orifices formed therein for air circulation therethrough and including an opening formed therein, a support element engaged in said opening and coupled to said board member;

means for securing said board member to said fins; and

,

a fan secured to said support element and located within said depression for circulating air.
