[0007] Compared with the prior art, the fan and the fan fixing device are provided with ribs and blocks on the side wall of the fan, and the baffles and the hooks and the elastic plates of the ribs and the blocks of the fan are respectively disposed on the side plates. The heat sink is provided with a card foot and a rib of the fan and a flap of the card and a spring piece having a groove, so as to fix the fan on the side plate or the heat sink, the structure is simple and the operation is convenient. [0008] Referring to FIG. 1 and FIG. 2, a first embodiment of a fan fixing device according to the present invention includes a fan 10 and a side plate 20 for fixing an electronic device housing of the fan 10. 097135141 Form No. A0101 Page 5 of 17 1003124202-0 1352280 Correction Replacement Page for April 12, 100 [0009] The fan 10 includes a square frame 12, an impeller 13 mounted at the center of the frame 12, and an impeller 13 peripheral multiple leaves 14. The frame 12 includes a first sidewall 121' - a second sidewall 122, a third sidewall 12 3 and a fourth sidewall 124. The first sidewall 121 is opposite to the third sidewall 12 3 , and the second sidewall 122 is opposite to the fourth sidewall 124 . Each of the side walls projects outwardly adjacent the bottom to form a rib 125. The outer surface of the rib 125 of the first side wall 121 and the third side wall 123 is adjacent to the fourth side wall 124, and the outer surface of the rib 125 of the second side wall 122 and the fourth side wall 124 is respectively protruded adjacent to the first side wall 121. There is a block 128 having a right-angled triangular cross section. Each of the blocks 12 8 has an abutting surface 1 2 6 adjacent to the adjacent side wall and a side 1 2 7 away from the adjacent side wall. [0010] The side panel 20 is provided with a square heat dissipation region 21 formed by a plurality of vent holes 212 corresponding to the fan 10. The side plate 20 is convexly provided with a fixing member arranged in a "gate" shape around the square heat dissipating region 21, and the fixing member includes an elastic line on a straight line adjacent to each of two opposite sides of the heat dissipating region 21. The plate 25 and the two hooks 24 facing the heat dissipating area 21 and a baffle 23 adjacent to the heat dissipating area 21 in the middle of the other side of the opposite end of the opposite side. The two elastic plates 25 are respectively adjacent to the other ends of the two opposite sides. [0011] With continued reference to FIG. 3, during assembly, the fan 10 is slid into the fixing member from between the two elastic plates 25 of the side plate 20. The ribs 125 at the bottom of the second and fourth side walls 122, 124 of the fan 10 respectively engage the corresponding hooks 24 on the side panels 20 and slide along the hooks 24. During this process, the slopes 127 of the blocks 128 of the second and fourth side walls 122, 124 respectively abut the two elastic plates 25 and push the two elastic plates 25 to elastically deform outward. When the fan 10 slides to 097135141 Form No. A0101 Page 6 of 17 Page 1003124202-0 1352280 On April 12, 100, the replacement page has its third side wall 123 abutting against the baffle 23 on the side panel 20, the first The latches 128 of the second and fourth side walls 122 126 are completely passed over the two elastic plates 25 respectively. The two elastic plates 25 are elastically restored and respectively resist the top surfaces 126 of the two blocks 128 of the second and fourth side walls 122 and 124. The fan 10 is fixed to the side panel 20. [0012] In consideration of the blowing direction of the fan 10, the fan 10 can also be fixed to the side panel 20 after being rotated 90 degrees counterclockwise with respect to the position of FIG. That is, the ribs 125 at the bottom of the first and third side walls 121 and 123 of the fan 10 are respectively engaged with the corresponding hooks 24 on the side plate 20, and the second side wall 122 of the fan 10 abuts against the baffle 23 on the side plate 20. The latches 128 of the first and third side walls 121 and 123 respectively pass over the two elastic plates 25, and the abutting surfaces 126 of the blocks 128 of the first and third side walls 121 and 123 respectively abut against the two elastic plates 25. [0013] When the fan 10 is removed, the two elastic plates 25 on the side plate 20 are pulled outward to separate the corresponding side walls 122 and 124 of the fan 10, or the blocks 128 on the 121 and 123, respectively. The two elastic plates 25 are locked so that the fan 10 can be withdrawn. [0014] Please refer to FIG. 4, which is a second embodiment of the fan fixing device of the present invention, which includes a fan 10 and a heat sink 30 for fixing the fan 10. The fan 10 is the fan in the first embodiment. 10. The heat dissipating device 30 includes a bottom plate 31, a plurality of heat dissipating fins 33 disposed on the bottom plate 31, and two fixing plates 35 respectively fixed to opposite sides of the heat dissipating fins 33. The tops of the two fixing plates 35 are slightly higher than the heat dissipation fins 33. The same end of the top of the two fixing plates 35 respectively extends a resilient piece 351, and each of the elastic pieces 351 is provided with a slot 352. Another 097135141 at the top of the two fixing plates 35 Form No. A0101 Page 7 / Total 17 pages 1003124202-0 1352280 __ On April 12, 100, the replacement page ends are respectively extended and bent inward to form a leg 354, each A leg 354 defines a transverse slot 35 5 . A top piece 358 is bent vertically inwardly between the elastic piece 351 and the leg 354 at the top of each fixing plate 35. [0016] With continued reference to FIG. 5, during assembly, the fan 10 is slid between the two elastic plates 351 of the heat sink 30 between the two fixed plates 35. The ribs 125 at the bottom of the first and third side walls 121, 123 of the fan 10 are respectively caught between the flaps 358 of the two fixing plates 35 and the top of the heat dissipation fins 33, and slide along the two flaps 358. During the process, the inclined surfaces 127 of the first and third side walls 121, 123 of the first and third side walls 121, 123 respectively abut the two elastic pieces 351 and push the two elastic pieces 351 to elastically deform outward. When the fan 10 slides to the lateral groove 355 of the leg 354 of the corresponding fixing plate 35, the second side wall 122 abuts against the leg 354 of the two fixing plates 35. The latches 128 of the first and third side walls 121 and 123 are respectively inserted into the slots 352 of the two elastic pieces 351. The two elastic pieces 351 are elastically restored, so that the fan 10 is fixed to the heat sink 30. [0017] In consideration of the blowing direction of the fan 10, the fan 10 can also be fixed to the heat sink 30 by rotating it 90 degrees clockwise with respect to the position of FIG. That is, the ribs 125 at the bottom of the second and fourth side walls 122, 124 of the fan 10 are respectively caught between the flaps 358 of the two fixing plates 35 and the top of the heat dissipation fins 33, and the third side wall 123 of the fan 10 is abutted. The latches 128 of the second and fourth side walls 122, 124 are respectively inserted into the slots 352 of the two elastic pieces 351. When the fan 10 is removed, the elastic pieces 351 of the two fixing plates 35 are outwardly pulled, so that the corresponding two side walls 122 and 124 of the fan 10, or the blocks 128 on the 121 and 123 are respectively separated from the two. The spring 351 is clamped, so that the 097135141 form number A0101 page 8/17 page 1003124202-0 100 April 12th correction replacement page 1352280 fan 10 can be extracted.
