If the heat generated by them is not removed in time, it will cause heat accumulation and temperature rise, which will seriously affect the positive fit of electronic components. . Μ, the industry usually installs two diffusers here to help its heat dissipation. At the same time, in order to ensure the heat dissipation efficiency of the radiator, a fan is usually installed on the fan to assist the heat dissipation. … &Amp; Generally, the heat sink is fixed to the electronic component by fasteners provided at its four corners, and the size of the outer frame of the fan is close to the size defined by the four corners of the heat sink. The space above the corner is too heavy. At this time, if the problem of installing the fan and the fastener is not properly handled, it is easy to cause interference between the fastener or the tool used to fix the fastener and the outer frame, which hinders the installation and removal of the heater. Therefore, a kind of fan fixing device is needed to fix the fan to the radiator for heat dissipation without hindering the installation and removal of the radiator. [New content ·] The purpose of the fixed 2 works is to provide a fan that does not hinder the installation and removal of the radiator. The upper cover includes an upper cover and a lower cover. The fan is fixed on the upper cover, 1 + 疋 邛 ο 下盍 There is no positioning part corresponding to the above-mentioned fixing part. The upper cover ^ fixing part is locked on the positioning part of the lower cover, and the upper cover and the τ cover can be moved relative to each other in the horizontal direction. The positioning part it can slide relatively, and rotate the upper cover so that it is staggered from the lower cover, so that the installation and removal of the radiator can be easily performed. [Embodiment] Please refer to the first and second figures, too prepared-lower cover M, for fixing the fan 2 = fixed upper fixing device 1 includes an upper cover 12 and the fan 2 including a square outer frame 22 and an impeller Alas, each of the four corner positions M264827 of the outer frame m is provided with a mounting hole 24. The heat sink 3 is provided with a plurality of heat sink fins 32, and two grooves 33 are respectively formed near the top ends of the two sides of the heat sink fins 32. Each corner of the heat sink 3 is provided with a buckle arm 34, and a fixing hole 36 is provided at the end of the buckle arm 34. It is fixed on the electronic component by a fastener such as a screw. The delta top cover 12 has a square shape, which has an outer frame 122 with a through hole in the center. A fixing portion 124 is provided in the center of the through hole. A plurality of evenly distributed spoiler ribs 126 connect the outer frame 122 and the fixed portion 124. Four corners of the outer frame 122 respectively extend upwardly to form a post 1222 with barbs at the ends. The fixing portion 124 includes a fixing plate 241, a plurality of elastic claws 1242, and four bumps 1246. The plurality of elastic claws 1242 project downwards integrally from the center of the fixing plate 1241 and are evenly distributed below the fixing plate 1241. A hook 1244 protruding outward is formed at the end of 242. The four protrusions 1246 are evenly distributed on the bottom surface of the fixing plate 1241 around the buckle claw 1242. The lower cover 14 has an outer frame 142 with a through hole in the center, and a positioning portion 144 is provided in the center of the through hole. A plurality of evenly distributed spoiler ribs 146 connect the outer frame 142 and the positioning portion 144. A cutout 1422 is formed at four opposite corners of the outer frame 142, and two opposite outer edges of the outer frame 142 respectively extend downward to form a fixing plate 1424. Each inner proximal end of the fixing plate 1424 is provided with oblique upward protrusions. Extend the buckle 1426. The shape of the positioning portion 144 matches the above-mentioned fixing portion 124. The center of the positioning portion 144 is a through hole 1442. The diameter of the through hole 1442 is smaller than that of the lower portion. A step 1443 is formed between the upper portion and the lower portion. Four sliding grooves 1444 are provided at positions corresponding to the convex points 1246, and two ends of the sliding grooves 1444 are deeply recessed to form two concave grooves 1446, and the shape is matched with the convex points 1246. Please refer to the third and fourth figures at the same time. When assembling, the fan 2 is squeezed through the mounting hole 24 of the post 1222 of the upper cover 12 so that the barb of the post 1222 is snapped on the fan 2 so that the fan 2 It is fixed on the upper cover 12, and the lower cover 14 is fixed to the radiator 3 by the positioning hooks of the fixing plate 424 and the hooks 1426 of the fixing plate 424 to the grooves 33 of the heat sink fins 32, and then the upper cover U equipped with the fan 2 is placed below On the cover 14, the _ portion 124 of the upper cover 12 is pressed down corresponding to the positioning portion 144 of the lower cover 14, and the claw 1242 of the fixing portion 124 passes through the through hole 1442 of the positioning portion 144 of the lower cover 14 elastically and inwardly through the hook 1244 The hook is hooked below the step 1443 to fix the upper cover 12 to the lower cover 14. At this time, the convex point 1246 of the fixing part 124 of the upper cover 12 is protruded into the lower part. The positioning of the cover 14 is equal to the groove 1444-the recess of the end, the upper cover 12 and the lower cover 14 are staggered from each other, and the fixing holes of the buckle arm 34 of the radiator 3 36 is located directly under the notch 1422 of the lower cover 14 and is not covered by the four corners of the fan 2, which is convenient for screwing and fixing the radiator 30. After the radiator 3 is fixed, apply force to the upper cover 12 or the fan 2 to rotate the upper cover 12, the claw 1242 of the fixing portion 124, M264827 rotates in the through hole 1442 of the positioning portion 144, and the concave point at the end 2 is raised! 446, at this time, the four corners of the fan 2 and the upper cover 12 are exactly in place! $ 二 Directly above the hole 36 'to complete the overall installation of the radiator 3 and the fan 2. In this work, "In the creation and disassembly of the radiator 3, you can turn 12 to make the four corners of the fan 2 deviate from the radiator; 3 fixing holes 36 of the 盍 3 screwing installation and removal In the completion phase, it is more convenient to install and remove the fan 2 at position ™ times _ 2; in addition, the fan 2 is fixed to the upper cover 12 through the pillar 1222 ^ ίί ==.
