After the through hole 232, the two elastic pieces 3124 are then restored to elastic deformation; the retaining ring 3121. of the actuating rod 31 then abuts against the top of the spring 35, and the elastic file 35 is gradually contracted to press down the bottom 25 of the fan 20, thereby causing the fan 20 to dissipate heat. The device 10 is in close contact with each other; then, when the locking portion 3153 of the moving rod 31 corresponds to the through hole 3852 of the fixing frame 38 and is lower than the position of the body 385, the operating portion 1312451 310 of the horizontal rotating action lever 31 is about 90° to The latching portion 3153 is perpendicular to the through hole 3852, and then the actuating lever 31 is lifted up so that the latching portion 3153 rises vertically to abut against the bottom of the recess 3850 of the mounting bracket 38, since the spring 35 is still contracted. In the state, the fan 20 is firmly pressed against the holder 38. When the fan 20 needs to be disassembled, the operating section 310 of the actuating lever 31 is first depressed to press the spring 35 such that the latching portion 3153 is vertically lowered to a position lower than the body 385, and then the operating section 310 is rotated by about 90. The removal of the fan 20 can be achieved by making the latching portion 3153 correspond to the through hole 3852 of the holder 38 and then lifting the lever 31 away from the holder 38. Referring to FIG. 7 and FIG. 10, the heat dissipating device 200 of the second embodiment of the present invention is similar to the heat dissipating device 100 of the first embodiment. The heat dissipating device 200 includes a heat sink 10b, a fan 20b, and the fan 20b is fixed to The fan clip 30b on the heat sink 10b. The heat sink 10b is substantially a three-dimensional square, and includes a flat square base lib. The plurality of heat sinks 130b and 131b extend upward from the top of the base lib, wherein the heat sinks 131b are symmetrically disposed on both sides of the heat sink 130b. A plurality of grooves extending in the lateral direction and the longitudinal direction are disposed between the heat dissipation sheets 130b and 131b; and the fins 130b distributed in the middle of the base lib are extended in length of the fins 131b distributed on the opposite edges of the base lib. The heat sink 10b is provided with four fastening holes 18b adjacent to opposite sides of the heat sink 131b. The fan 20b includes a rectangular frame 21b. The frame 21b has four through holes 232b at four corners. Each of the through holes 232b includes a top hole (not shown) near the top end of the frame 21b and a bottom end of the frame 21b. Bottom hole (not shown). The fan clip 30b includes a four actuating lever 31b, a four-cylindrical spring 35, and two two 13 1312451 mounting brackets 38b. Referring to Figure 8, the actuating lever 31b includes an operating section 310b, a positioning section - 315b, and a pressing section 312b between the operating section 310b and the positioning section 315b. The actuating lever 31b has substantially the same structure as the actuating lever 31 of the first embodiment. The difference between the two is that the engaging portion 3123b of the actuating lever 31b is not provided with the elastic piece 3124, the retaining ring 3121, and the slots 3120 and 3122. The abutting portion 3121b of the actuating rod 31b has a larger diameter than the inner diameter of the spring 35, and the engaging portion 3123b has a smaller diameter than the inner diameter of the spring 35. Referring to Fig. 9, the holder 38b includes a long rectangular body 385b, and the longitudinal edge extends vertically from a connecting arm 381b. The connecting arm 381b has two ends 382b extending perpendicularly away from the body 385b, and a rectangular through hole 3822b is formed in the lateral direction of each of the lugs 382b. The through hole 3822b is shaped like the actuating rod 31b. The latching portion 3153b corresponds to a slightly larger size for the latching portion 3153b to pass through. Two opposite holes 3822b are formed with two protrusions 3825b, and the two protrusions 3825b have a pitch corresponding to the width of the snap portion 3153b to engage the latching portion 3153b of the actuating lever 31b therebetween. The two sides of the body 385b opposite to the connecting arm 381b extend perpendicularly to the side opposite to the extending direction of the connecting arm 381b, and a rectangular hole 388b is formed on each of the fastening pieces 388b. Each of the fastening pieces 388b is provided with a circular hole 3888b; In the middle of the same side edge of the piece 388b, a folded edge 389b is extended toward the opposite side of the extending direction of the buckle piece 388b for operating the holding frame 38b. When assembling, the two fixing brackets 38b are overlapped on the opposite sides of the heat sink 10b with the fastening holes 18b, so that the body 385b of the fixing frame 38b covers the top of the heat sink 131b, and the lug 382b covers the top of the heat sink 130b, Fixing 12 1312451 The cleat 388b of the frame 38b is close to the side of the heat sink 10b, and the round hole 3888b of the cleat 388b corresponds to the fastening hole 18b of the heat sink 10b, and the four screws 40 pass through the circular hole 3888b and the fastening hole 18b. The fixing bracket 38b is fixedly connected to the heat sink 10b. Then, the fan 20b is placed on the top of the heat sink 10b, and the through holes 232b at the four corners of the fan 20b correspond to the through holes 3822b of the holder 38b. Here, the outer diameter of the spring 35 is smaller than the inner diameter of the top hole in the through hole 232b of the fan 20b, and the outer diameter of the spring 箦35 is larger than the inner diameter of the bottom hole of the through hole 232b, and the engaging portion 3123b and the rod 3151b of the actuating rod 31b The size of the locking portion 3153b is smaller than the inner diameter of the bottom hole of the through hole 232b. Therefore, the four springs 35 are received in the through holes 232b, and the operating portion 310b of the operating lever 31b is operated to make the locking portion 3153b and the supporting rod 3151b, the connecting portion 3123b sequentially passes through the through hole 232b of the fan 20b, the spring 35; the abutting portion 3121b of the writing rod 31b abuts against the top of the spring 35, so that the spring 35 is gradually contracted, and the engaging portion 3153b of the moving rod 31b is correspondingly worn. When the through hole 3822b of the fixing frame 38b is lower than the end position of the protruding post 3825b of the lug 382b, the horizontal rotating operation section 310b is about 90° to a position where the locking portion 3153b is perpendicular to the through hole 3822b, and then lifted up so that the card is lifted. The buckle portion 3153b is fastened between the two protrusions 3825b at the edge of the through hole 3822b. Since the spring 35 is still in the contracted state, the fan 20b is firmly pressed against the lug 382b of the fixing frame 38b. When the fan 20b needs to be disassembled, the handle pressing spring 35 of the actuating lever 31b is first operated so that the latching portion 3153b is vertically lowered to a position lower than the end of the stud 3825b, and then rotated by 90° so that the latching portion 3153b corresponds to the fixing bracket 38b. The hole 3822b is then separated from the fixed frame 38b by lifting up the actuating lever 31b, so that the fan 20b can be removed. In summary, by means of the buckles 30, 30b, the assembly and disassembly of the fans 20, 20b and the heat sinks ι, i 〇 b can be realized simply by operating the 13 1312451 actuators 31, 31b. ,Convenience.
