base

41,43 is formed with tabs 412,432 respectively, and at first 41,43 levels extend internally and then bending extension vertically downward from the limit to tabs 412,432 for each.Each tabs 412,432 is provided with through

hole

4120,4320, thus screw 70 pass these through

holes

4120,4320 so that with the screwed hole 142 of the reinforcement fin 140 of radiator 10 mutually screw lock fan Fixture 40 is installed on the radiator 10.The side that is positioned at fan Fixture 40 2 clinodiagonal tabs 412,432 is formed with

grab

4122,4322, in order to fastener 30 fasteners.One C shape buckle ear 415,435 outwards is bent to form from flanging 410,430 respectively.The retaining piece 422 that a pair of interval is provided with makes progress and bends inwards from flanging 420 and forms to prevent that against fan 60 it is from moving relative to fan Fixture 40.The shell fragment 442,443 at a pair of interval is formed at the opposite end of flanging 440 respectively, wherein shell fragment 442 earlier from flanging 440 inwardly extend upward then again horizontal-extending with and base 44 between form a receiving space to accommodate operating parts 50, shell fragment 443 is near shell fragments 442, and it extends upward and form in order to against positional operand workpiece 50 from flanging 440.

See also Fig. 1 and Fig. 4, each operating parts 50 through repeatedly being bent to form, comprises the operating portion 54 that a pivot part 52 and vertically extends from pivot part 52 1 ends by a Metallic rod.The free end back bending of operating portion 54 is beneficial to operation.This pivot part 52 comprises that two are in collinear pivot 520, inner relatively vertically extending two linkage sections 522 of this two pivot 520 and connect the U-shaped pressure section 524 on two linkage sections, 522 tops certainly.When operating parts 50 is assembled on the fan Fixture 40, pressure section 524 places between the shell fragment 442,443 of fan Fixture 40, wherein a pivot 520 is placed in the receiving space of

shell fragment

442 and 44 formation of its place tabs, another 443 on adjacent shell fragment is resisted against another pivot 520, thereby pivot part 52 is rotatably installed on the fan Fixture 40.

See also Fig. 1 and Fig. 6, fan 60 comprises a rectangle framework, and this framework has a top board 62 and the base plate 64 parallel with this top board 62.Fan 60 is installed on the top of fan Fixture 40, the retaining piece 422 of this fan Fixture 40 compresses the top of the base plate 64 of fan 60, and the operating portion 54 of operating parts 50 compresses fan 60 respective base 64 around pivot part 52 rotations with the pressure section 524 that drives operating parts 50.As shown in Figure 7, fan 60 just firmly is installed on the fan Fixture 40 when operating parts 50 fasteners are on the buckle ear 415,435 of fan Fixture 40 both sides.

See also Fig. 1 to Fig. 2, each fastener 30 is formed by Metallic rod one bending.This fastener 30 comprises a rotating shaft 32, an axis of rotation 32 levels outwards U-shaped buckling parts 34 and and these rotating shaft 32 1 ends operating portion 36 connected vertically of bending.Wherein, this operating portion 36 is through being " P " shape after the bending several times, so that convenient manual operation.Thereby bending is extended and near the other end of rotating shaft 32 and away from operating portion 36 this rotating shaft 32 is divided into and is positioned at collinear and discontinuous two parts on these buckling parts 34 axis of rotation 32.

During assembling, please also refer to as Fig. 2 and Fig. 6, the rotating shaft 32 of fastener 30 wears in the draw-in groove between the second splint 122 that is positioned at radiator 10, operating portion 36 is positioned at two diagonally opposing corner sides of radiator 10, this fastener 30 can be around its rotating shaft 32 relative these radiators 10 rotations, simultaneously the buckling parts 34 of this fastener 30 can be by rotating in the draw-in groove of this rotating shaft 32 between clamping plate 122 relatively fixedly the fixture block 242 of module 20 close or away from; As shown in Figure 6, the receiving space 240 (shown in Figure 2) of this buckling parts 34 between fixture block 242 and retaining wall 24 and unsettled, this moment, the heat abstractor combination was in not buckling state.

The fastening process please refer to Fig. 7 and Fig. 8.During fastening, the operating portion 36 of start fastener 30 makes it around the shaft 32 towards the direction rotation near the

grab

4122,4322 of fan Fixture 40, so that the buckling parts 34 of fastener 30 places the below of the bottom cambered surface 243 of fixture block 242 from bottom to top towards fixedly fixture block 242 motions of module 20 until buckling parts 34; With the

grab

4122,4322 of operating portion 36 and fan Fixture 40 buckle mutually, this buckling parts 34 contacts also fastening by the rotation of operating portion 36 with the bottom cambered surface 243 of fixture block 242.

So far, present embodiment is described in detail in conjunction with the accompanying drawings, and described heat sink arrangement combining structure is simple, and then manufacturing cost can effectively reduce; To radiator 10 fixedly the time, because the terminal distances to rotating shaft 32 of the operating portion 36 of fastener 30 are than buckling parts 34 terminal distances to rotating shaft 32, by lever principle as can be known, the operation during installation is firmly less; This fastener 30 is positioned at two sides of radiator 10, and it is less to take installing space when mounted, and radiator 10 need not be vacateed installing space especially, does not influence the area of dissipation setting.
