Abstract
Abstract A positioning device for a heat sink on computer chips (CPU) includes a seat placed on the CPU for mounting a fan and having a fixed clamping member on one end for hooking onto a shoulder of the CPU and a movable clamping member for hooking another shoulder of the CPU. An elastic element is disposed between the seat and the movable clamping member to enable the movable clamping member to hook the CPU by the restoring force thereof and which has two ends extending to both sides of the seat which are folded down to abut both ends of the CPU opposite to each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A separable heat sink for a CPU comprising: a seat having a fan thereon, the seat comprising a fixed clamping member on one side of said seat, the first clamping member having a folded first hook provided on a bottom thereof configured to engaged a first shoulder of said CPU; a movable clamping member movable between open and closed positions and having a second hook provided on a bottom thereof configured to engage a second shoulder of said CPU opposite said first shoulder when the movable clamping member is in its closed position, a top end of said movable clamping member being located adjacent to a lateral side of said seat; and an elastic element connecting said seat and said movable clamping member so as to bias the movable clamping member toward its closed position, the elastic element having opposite ends extending to opposite sides of said seat wherein said ends are folded down to form two stop members to abutting opposite sides of said CPU.
Claim 2
Dependent Claim
166 words
A separable heat sink for a CPU comprising: a seat having a fan thereon, the seat comprising a fixed clamping member on one side of said seat, the first clamping member having a folded first hook provided on a bottom thereof configured to engaged a first shoulder of said CPU; a movable clamping member movable between open and closed positions and having a second hook provided on a bottom thereof configured to engage a second shoulder of said CPU opposite said first shoulder when the movable clamping member is in its closed position, a top end of said movable clamping member being located adjacent to a lateral side of said seat; and an elastic element connecting said seat and said movable clamping member so as to bias the movable clamping member toward its closed position, the elastic element having opposite ends extending to opposite sides of said seat wherein said ends are folded down to form two stop members to abutting opposite sides of said CPU.
Claim 3
Dependent Claim
59 words
The separable heat sink as stated in claim 1, wherein said elastic element comprises: a metallic wire in which: the opposite ends are folded down and wound for several turns to form windings constituting said stop members; and the opposite ends also form a pair of fixing bars extending parallel to each other so as to engage the seat.
Claim 4
Dependent Claim
56 words
The separable heat sink as stated in claim 2, wherein said seat has a receiving groove located adjacent to said movable clamping member to receive fixing bars of the elastic element and said movable clamping member has a fixing portion located opposite to said receiving groove, so as to receive a portion of the elastic element.
Claim 5
Dependent Claim
53 words
The separable heat sink as stated in claim 3, wherein a top portion of said seat is provided with a plurality of heat sinking leaves extending parallel to said fixed clamping member, and wherein said receiving groove is provided on a base of one of said leaves adjacent to said movable clamping member.
Claim 6
Dependent Claim
29 words
The separable heat sink as stated in claim 3, wherein said fixing portion is formed by an upper portion of said movable clamping member located adjacent to said seat.
Claim 7
Dependent Claim
24 words
The separable heat sink as stated in claim 1, said first and second hooks extend down and inwardly for hooking shoulders of said CPU.
