[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, this embodiment provides an embodiment of a high-efficiency heat dissipation fan based on an improved fan module.

[0025] A high-efficiency heat dissipation fan improved based on a fan module, comprising a heat sink 1, a mounting frame 2 fixedly mounted on the top of the heat sink 1, two heat dissipation fan bodies 3 symmetrically mounted on the mounting frame 2, fixing plates 4 fixedly mounted on both sides of the mounting frame 2, a fan frame 5 connected to the fixing plate 4 by screws is arranged above the heat dissipation fan body 3, a flow space 6 is opened on the fan frame 5, a dustproof structure 7 is arranged on the top of the fan frame 5, the dustproof structure 7 comprises a fixing frame 8 mounted on the fan frame 5, a dustproof net 9 is fixedly mounted inside the fixing frame 8, support blocks 10 are fixedly mounted on both sides of the fan frame 5, and connecting blocks 11 connected to the support blocks 10 are fixedly mounted on both sides of the fixing frame 8. The dustproof structure 7 can be provided to prevent dust. A dustproof net 9 fixed by a fixing frame 8 is provided on the outer side of the fan frame 5. The dustproof net 9 can block external dust and prevent dust from adhering to the cooling fan body 3 or even entering the inside of the chassis, thereby avoiding pollution to the inside of the chassis and affecting heat dissipation. At the same time, the two cooling fan bodies 3 are set to rotate in forward and reverse directions and the flow space 6 is set to be through, which can enhance the wind speed flow field and improve the heat dissipation power. It can be used in conjunction with electronic component devices to achieve the effect of rapid heat dissipation.

[0026] Two springs 12 are symmetrically installed inside the support block 10, a slider 13 is fixedly installed at one end of the spring 12, a limit plate 14 is fixedly installed on the top of the slider 13, a plurality of limit grooves 15 that engage with the limit plate 14 are provided inside the connecting block 11, one side of the limit plate 14 is set to an inclined shape, empty grooves 23 are provided on both sides of the support block 10, a pressing rod 16 that passes through the empty groove 23 is fixedly installed on one side of the slider 13, two slide grooves 17 are symmetrically provided on the inner wall of the empty groove 23, and slide rods 18 slidably connected to the slide groove 17 are fixedly installed on both sides of the pressing rod 16. Through the arrangement of the spring 12, the slider 13, the limit plate 14, the limit groove 15, the pressing rod 16 and the empty groove 23, the support block 10 is provided with two limit plates 14 connected by the spring 12 and the slider 13. When the fixed frame 8 is installed on the surface of the fan frame 5, the connecting blocks 11 on both sides of the fixed frame 8 are sleeved on the two limit plates 14, and the limit plates 14 are engaged with the limit grooves 15, so that the fixed frame 8 is fixed under the action of the engagement, so that the fixed frame 8 is not easy to fall off from the fan frame 5, and at the same time, the two pressing rods 16 are pressed. Pressing can cause the two limit plates 14 to shrink and disengage from the limit grooves 15, and then the fixing frame 8 can be removed from the fan frame 5, making it convenient to replace or clean the dust screen 9. Through the arrangement of the slide groove 17 and the slide rod 18, since the slide groove 17 and the slide rod 18 are slidably connected, the friction between the pressing rod 16 and the empty groove 23 can be reduced unevenly, making it easier to move. At the same time, it can also limit the pressing rod 16 and prevent it from shaking, so as to support the limit plate 14 and make the engagement with the limit groove 15 more stable.

[0027] The fixing plate 4 is provided with a plurality of positioning grooves 19, and a plurality of positioning rods 20 used in conjunction with the positioning grooves 19 are fixedly installed at the bottom of the fan frame 5. The diameter of the bottom of the positioning rod 20 is smaller than the diameter of the top. Two rollers 21 are fixedly installed inside the positioning groove 19, and grooves 22 that cooperate with the rollers 21 are provided on both sides of the positioning rod 20. Through the arrangement of the positioning grooves 19 and the positioning rods 20, the fan frame 5 and the fixing plate 4 can be positioned when they are installed, making the installation of the fan frame 5 more convenient. By setting the bottom diameter of the positioning rod 20 to be smaller than the top diameter, the positioning rod 20 is easier to insert into the positioning groove 19. Through the arrangement of the rollers 21 and the grooves 22, when the positioning rod 20 is inserted into the positioning groove 19, the rollers 21 roll in the grooves 22, which can reduce the friction between the positioning rod 20 and the inner wall of the positioning groove 19, so that the positioning rod 20 falls more quickly.

[0028] In this embodiment, if Figure 1-Figure 5 As shown, the working process of a high-efficiency heat dissipation fan based on the improvement of the fan module provided in this embodiment is as follows:

[0029] When the fixing frame 8 is installed on the surface of the fan frame 5, the connecting blocks 11 on both sides of the fixing frame 8 are sleeved on the two limit plates 14, and the limit plates 14 are engaged with the limit grooves 15, so that the fixing frame 8 is fixed under the action of the engagement, so that the fixing frame 8 is not easy to fall off from the fan frame 5, and the dustproof net 9 can block the external dust, prevent the dust from adhering to the cooling fan body 3 or even entering the inside of the chassis, and can avoid pollution to the inside of the chassis and affecting the heat dissipation. At the same time, pressing the two pressing rods 16 can shrink the two limit plates 14 and cancel the engagement with the limit grooves 15, and then the fixing frame 8 can be removed from the fan frame 5, so that the dustproof net 9 can be replaced or cleaned conveniently. The two cooling fan bodies 3 are set to rotate in forward and reverse directions and the flow space 6 is set to be through, which can enhance the wind speed flow field and improve the heat dissipation power. It can be used in conjunction with electronic component devices to achieve the effect of rapid heat dissipation.

[0030] In summary, in the present embodiment, according to a high-efficiency heat dissipation fan improved based on the fan module of the present embodiment, through the arrangement of the spring 12, the slider 13, the limit plate 14, the limit groove 15, the pressing rod 16 and the empty groove 23, the support block 10 is provided with two limit plates 14 connected by the spring 12 and the slider 13, when the fixed frame 8 is installed on the surface of the fan frame 5, the connecting blocks 11 on both sides of the fixed frame 8 are sleeved on the two limit plates 14, and the limit plates 14 are engaged with the limit grooves 15, so that the fixed frame 8 is fixed under the action of the engagement, so that the fixed frame 8 is not easy to fall off from the fan frame 5, and pressing the two pressing rods 16 at the same time can make the two limit plates 14 shrink and cancel the engagement with the limit grooves 15, and then the fixed frame 8 can be removed from the fan frame 5, so that the dustproof net 9 can be replaced or cleaned conveniently, and the dustproof net 9 can be replaced or cleaned conveniently through the sliding grooves 17 and the sliding rods 18. The arrangement, since the slide groove 17 and the slide rod 18 are slidably connected, the unevenness can reduce the friction between the pressing rod 16 and the empty groove 23, making it easier to move. At the same time, it can also limit the pressing rod 16 to prevent it from shaking, so as to support the limiting plate 14, making the engagement with the limiting groove 15 more stable. Through the arrangement of the positioning groove 19 and the positioning rod 20, it can play a positioning role when installing the fan frame 5 and the fixing plate 4, making the installation of the fan frame 5 more convenient. By setting the bottom diameter of the positioning rod 20 to be smaller than the top diameter, the positioning rod 20 is easier to insert into the positioning groove 19. Through the arrangement of the roller 21 and the groove 22, when the positioning rod 20 is inserted into the positioning groove 19, the roller 21 rolls in the groove 22, which can reduce the friction between the positioning rod 20 and the inner wall of the positioning groove 19, so that the positioning rod 20 falls faster.
