請參閱圖3至圖5,散熱裝置組裝時,首先,固定架10放置於底座30上、二散熱片組40之間,風扇20收容於固定架10之側臂14及夾持部18所圍成之空間內,且夾持部18之擋板180正好置於風扇20底部之凸耳22形成之卡槽24 內,此時風扇20之一對前後側邊夾緊於二夾持部18之間。接著,四個固定件80順次穿過固定架10側臂14之連接部140之穿孔1400、本體12之固定孔120螺鎖於設於底座30靠近四角處之螺孔32內,最終將固定架10螺鎖於底座30上。於固定件80螺緊過程中,固定架10側臂14由於受到固定件80向下之作用力而逐漸貼近固定架10之本體12,即側臂14之連接部140靠近本體12上,同時卡持部142貼近風扇20之一對左右側邊,並使卡持部142之凸點1420緊緊卡入位於風扇20底部凸耳22之扣孔220內,風扇20之左右側邊被側臂14之卡持部142緊緊夾置其中。由於固定架10之夾持部18夾持於風扇20之前後側邊,避免了風扇20於固定架10內沿其前後側做水平方向之位移;又因固定架10之夾持部18之擋板180置於風扇20底部之每對凸耳22之間,且側臂14之夾持部18夾緊於風扇20之左右二平板上(見圖2),避免風扇20於固定架10內沿風扇20左右側邊水平位移;固定架10側臂14之卡持部142上之凸點1400卡入風扇20底部凸耳22之扣孔220內,避免風扇20於固定架10內沿垂直於本體12之方向上下移動。 Referring to FIG. 3 to FIG. 5 , when the heat dissipating device is assembled, first, the fixing frame 10 is placed on the base 30 and between the two fin groups 40 , and the fan 20 is received in the side arm 14 and the clamping portion 18 of the fixing frame 10 . In the space formed, the baffle 180 of the clamping portion 18 is placed on the card slot 24 formed by the lug 22 at the bottom of the fan 20 Inside, at this time, one of the fans 20 is clamped between the two clamping portions 18 with respect to the front and rear sides. Then, the four fixing members 80 are sequentially passed through the through holes 1400 of the connecting portion 140 of the side arm 14 of the fixing frame 10, and the fixing holes 120 of the body 12 are screwed into the screw holes 32 provided at the four corners of the base 30, and finally the fixing frame is fixed. 10 is screwed onto the base 30. During the tightening process of the fixing member 80, the side arm 14 of the fixing frame 10 gradually approaches the body 12 of the fixing frame 10 by the downward force of the fixing member 80, that is, the connecting portion 140 of the side arm 14 is close to the body 12, and the card is simultaneously The holding portion 142 is adjacent to one of the left and right side edges of the fan 20, and the bump 1420 of the holding portion 142 is tightly engaged in the buttonhole 220 of the lug 22 at the bottom of the fan 20. The left and right sides of the fan 20 are side arms 14 The catch portion 142 is tightly sandwiched therebetween. Since the clamping portion 18 of the fixing frame 10 is clamped on the front and rear sides of the fan 20, the horizontal displacement of the fan 20 in the fixing frame 10 along the front and rear sides thereof is avoided; and the clamping portion 18 of the fixing frame 10 is blocked. The plate 180 is placed between each pair of lugs 22 at the bottom of the fan 20, and the clamping portion 18 of the side arm 14 is clamped to the left and right plates of the fan 20 (see FIG. 2) to prevent the fan 20 from being inside the fixed frame 10. The left and right sides of the fan 20 are horizontally displaced; the bump 1400 on the latching portion 142 of the side arm 14 of the mounting frame 10 is inserted into the buttonhole 220 of the bottom lug 22 of the fan 20 to prevent the fan 20 from being perpendicular to the body in the fixing frame 10 Move in the direction of 12 up and down.
本發明中,固定架10可沿風扇20之前後、左右及上下位置加以固定,增強風扇20相對於固定架10之穩定性,使整個散熱裝置之結構更加穩固。此外,固定架10通過螺釘80螺合於底座30之方式固定於底座30,不與底座30上之散熱片組40配合,既不給散熱片40增加負擔,又簡化固定架10之安裝過程,同時由於側臂14之連接部140與底 座30之間設有間隙,當固定件80向下鎖緊時所產生之力由於連接部140與底座30之間隙而分解,從而通過其分解力自兩邊向中間擠壓來固定風扇20,使風扇20更加穩固之固定於底座30上。 In the present invention, the fixing frame 10 can be fixed along the front, rear, left and right and upper and lower positions of the fan 20 to enhance the stability of the fan 20 relative to the fixing frame 10, so that the structure of the entire heat dissipating device is more stable. In addition, the fixing frame 10 is fixed to the base 30 by screwing the screw 80 to the base 30, and does not cooperate with the heat sink group 40 on the base 30, thereby not burdening the heat sink 40 and simplifying the installation process of the fixing frame 10. At the same time, due to the connection portion 140 and the bottom of the side arm 14 A gap is provided between the seats 30, and the force generated when the fixing member 80 is locked downward is decomposed by the gap between the connecting portion 140 and the base 30, so that the fan 20 is fixed by pressing the decomposing force from the both sides to the middle, so that the fan 20 is fixed. The fan 20 is more firmly fixed to the base 30.
