[0025] The detailed implementation manners of the present utility model are introduced with reference to the accompanying drawings.

[0026] Reference Figure 1 and Figure 2 , Figure 1 is a three-dimensional structural schematic diagram of a heat dissipation fan with a side dot matrix light-emitting effect. The heat dissipation fan is overall in a cuboid shape, the air duct 21 for heat dissipation is in the center, and the outer shell 1 has a concave light-emitting groove 11 on the side. An arc-shaped light-emitting component 3 is arranged in the light-emitting groove 11. Figure 2 is a three-dimensional structural schematic diagram of the heat dissipation fan with a side dot matrix light-emitting effect after removing the translucent plate 34. After removing the translucent plate 34, it can be seen that the multiple light-emitting lamp beads 32 of the light-emitting component 3 are distributed in the light-emitting groove 11 in a matrix arrangement. The translucent plate 34 is used to filter the light emitted by the light-emitting lamp beads 32. The multiple light-emitting lamp beads 32 can emit light at multiple points, forming a dot matrix light-emitting lighting effect on the side of the heat dissipation fan, so that the heat dissipation fan can have good-looking lights for people to watch when in use, improving the atmosphere.

[0027] Reference Figures 1 to 5 , a heat dissipation fan with a side dot matrix light-emitting effect, includes an outer shell 1, a fan blade 2, and a light-emitting component 3. An air duct 21 is arranged in the center of the outer shell 1. The fan blade 2 is mounted in the center of the air duct 21 through a support frame 22. Two opposite outer side walls of the outer shell 1 are respectively provided with light-emitting grooves 11, and the light-emitting grooves 11 are not located at both ends of the outer shell 1 in the thickness direction; the light-emitting component 3 is arranged in the light-emitting grooves 11, and the light-emitting component 3 includes multiple light-emitting lamp beads 32. The multiple light-emitting lamp beads 32 are distributed in the light-emitting grooves 11 in a matrix arrangement, forming a dot matrix light-emitting surface 30 on the side of the outer shell 1.

[0028] It should be further noted that the number of the light-emitting grooves 11 provided on the outer shell 1 is determined by the shape of the outer shell 1 and the lighting effect. In addition to providing the light-emitting grooves 11 on two opposite outer side walls of the outer shell 1, the light-emitting grooves 11 can also be provided only on one outer side wall, or on three adjacent outer side walls, or even on all four outer side walls; the light-emitting grooves 11 are used to install the light-emitting components 3 to form a dot matrix light-emitting surface 30. The light strip 31 and the bracket 33 of the light-emitting component 3 have a certain thickness and require a light-emitting groove 11 with a certain depth for installation. The depth of the light-emitting groove 11 is adjusted according to the shape of the outer shell 1 and the entire cooling fan. The light-emitting groove 11 can be set shallower, so that after the light-emitting component 3 is installed in the light-emitting groove 11, the outermost light-transmitting plate 34 of the light-emitting component 3 is flush with the outer side wall of the outer shell 1 or protrudes a certain height relative to the outer side wall of the outer shell 1. The light-emitting groove 11 can be set deeper. For example, in the light-emitting groove 11 of the embodiment of the present application, the light-emitting groove 11 is internally tangent to the inner wall of the air duct 21. After the light-emitting component 3 is installed in the light-emitting groove 11, the outermost light-transmitting plate 34 of the light-emitting component 3 is concave relative to the outer side wall of the outer shell 1.

[0029] For the cooling fan with a side dot matrix lighting effect of the present application, by providing the light-emitting grooves 11 on the outer side walls of the outer shell 1 and arranging a plurality of light-emitting beads 32 distributed in a matrix arrangement in the light-emitting grooves 11, a dot matrix is formed after the plurality of light-emitting beads 32 are lit, so that a side dot matrix lighting effect is formed on the outer shell 1, enabling the cooling fan to have good-looking lights for people to watch during use and enhancing the atmosphere.

[0030] To make the cooling fan more visually appealing, in this embodiment, referring to Figures 1 to 5 , the dot matrix light-emitting surface 30 is an arc-shaped light-emitting surface.

[0031] It can be understood that with such a setting, the dot matrix light-emitting surface 30 protrudes outward, and the inner wall of the air duct 21 is internally tangent to the dot matrix light-emitting surface 30, forming a dot matrix lighting effect that cooperates with the rotation of the fan blade 2. In addition, the dot matrix light-emitting surface 30 can also be a concave arc surface or a flat surface. Different dot matrix light-emitting surfaces 30 can cooperate with the shape of the outer shell 1 to form different dot matrix lighting effects, which is beneficial to expanding the audience of the radiator and meeting the needs of different audiences.

[0032] To generate the dot matrix lighting effect, in this embodiment, referring to Figure 2 and Figure 3, the light-emitting component 3 includes a light strip 31, a plurality of light-emitting beads 32, a bracket 33, and a light-transmitting plate 34. The light strip 31 is fixed in the light-emitting groove 11. The plurality of light-emitting beads 32 are arranged in a matrix on the light strip 31. The bracket 33 is light-impermeable. The bracket 33 is arranged on the light-emitting side of the light strip 31. The bracket 33 is provided with light-emitting holes 331 at positions corresponding to the light-emitting beads 32. Each light-emitting bead 32 is located in a corresponding light-emitting hole 331. The light-transmitting plate 34 is arranged on the light-emitting side of the light strip 31 through the bracket 33 to filter the light emitted by the light-emitting beads 32.

[0033] It can be understood that with such an arrangement, the light strip 31 is used to install the light-emitting beads 32 and supply power to the light-emitting beads 32. The bracket 33 is used for light shielding, so that the light emitted by the light-emitting beads 32 can only irradiate through the light-emitting holes 331 to the light-transmitting plate 34, reducing the irradiation range of the light-emitting beads 32, and preventing the light emitted by the plurality of light-emitting beads 32 from intersecting, thereby forming a dot matrix light-emitting effect. Then, the light-transmitting plate 34 is used to filter the light generated by the light-emitting beads 32, so that the light transmitted through the light-transmitting plate 34 is attenuated to a non-glare state, thus making the dot matrix light effect generated by the dot matrix light-emitting surface 30 have a better visual experience and improving the sense of pleasure.

[0034] In order to form an arc-shaped dot matrix light-emitting surface 30, in this embodiment, refer to Figure 3 , the light strip 31 is a flexible light strip 31, and adjacent light strips 31 are electrically connected through a flexible flat cable 35.

[0035] It can be understood that with such an arrangement, the flexible light strip 31 can be bent according to the light-emitting grooves 11 with different curvatures. The bent light strip 31 can form an arc-shaped dot matrix light-emitting surface 30, and can also form an inwardly concave, outwardly convex or flat dot matrix light-emitting surface 30 according to the shape of the light-emitting groove 11, making the light strip 31 compatible with more installation environments and reducing the development cost of the light strip 31.

[0036] In order to better form an arc-shaped dot matrix light-emitting surface 30, in this embodiment, refer to Figures 2 to 5 , the bracket 33 is an arc-shaped plate-like bracket 33.

[0037] It can be understood that with such an arrangement, the arc-shaped bracket 33 can better match the light-emitting groove 11 with a curvature, so as to better limit the bent light strip 31 in the light-emitting groove 11, enabling the bracket 33 to be closely attached to the light strip 31 and reducing the possibility of light leakage.

[0038] In order to fix the bracket 33 in the housing 1, in this embodiment, refer to Figures 3 to 5 , the bracket 33 protrudes with protrusions 332 in a direction away from the light strip 31. One protrusion 332 is provided at each end of the bracket 33. The housing 1 is correspondingly provided with limiting grooves 13, and the protrusions 332 are clamped in the limiting grooves 13 to fix the bracket 33 and the housing 1.

[0039] It can be understood that with such a setting, the bracket 33 is an arc-shaped plate-like body. The end face of the outer shell 1 is relatively thin and not suitable for fixing the bracket 33. There is a relatively large space at the corner of the outer shell 1. The limiting groove 13 is arranged at the corner of the outer shell 1 and is clamped with the bumps 332 at both ends of the bracket 33, so that the bracket 33 can be stably fixed in the outer shell 1. At the same time, the position of the bump 332 is far from the light-emitting hole 331 and will not affect the lighting effect.

[0040] In order to fix the light-transmitting plate 34, in this embodiment, referring to Figure 3 and Figure 4 , the light-transmitting plate 34 is an arc-shaped plate-like light-transmitting plate 34, and the light-transmitting plate 34 is fixed between the two bumps 332 of the bracket 33.

[0041] It can be understood that with such a setting, a slot is formed between the two bumps 332 of the bracket 33. The light-transmitting plate 34 is set to a shape and size matching the slot, so that both ends of the light-transmitting plate 34 are in contact with the two bumps 332. The light-transmitting plate 34 can be fixed in the slot formed between the two bumps 332 by welding or bonding. The surface shell 15 extends a pressing block 16 towards the slot on one side of the limiting groove 13. After the bracket 33 is installed in the light-emitting groove 11, the bump 332 is snapped into the limiting groove 13, and the pressing block 16 presses the light-transmitting plate 34, so that the light-transmitting plate 34 is stably arranged in the slot formed between the two bumps 332.

[0042] In order to facilitate assembly, in this embodiment, referring to Figures 1 to 5 , the outer shell 1 includes a bottom shell 14 and a surface shell 15. The bottom shell 14 and the surface shell 15 are buckled with each other. The bottom shell 14 is provided with clamping grooves 12 on both sides of the light-emitting groove 11, and both ends of the light strip 31 are respectively snapped into the corresponding clamping grooves 12 to be positioned in the light-emitting groove 11.

[0043] It can be understood that with such a setting, the outer shell 1 adopts an assembly method of buckling the bottom shell 14 and the surface shell 15 with each other, so that the light-emitting component 3 can be first installed on the bottom shell 14 and then the surface shell 15 is buckled, reducing the assembly difficulty and facilitating assembly, which can improve the yield of the product. The clamping grooves 12 are arranged on both sides of the light-emitting groove 11, and the light strip 31 is fixed in the light-emitting groove 11 through the clamping grooves 12. The clamping grooves 12 are located inside the outer shell 1, which can reduce the structure and traces of the outer shell 1 of the assembled light-emitting component 3 exposed on the surface of the outer shell 1, making the surface of the outer shell 1 cleaner and more beautiful.

[0044] In order to better buckle the bottom shell 14 and the surface shell 15, in this embodiment, referring to Figures 3 to 5 , the bottom shell 14 is provided with a buckling position 18, and the surface shell 15 is correspondingly provided with a hook 17. The bottom shell 14 and the surface shell 15 are fixed by snapping the hook 17 into the buckling position 18.

[0045] It can be understood that with such an arrangement, the hook 17 of the front shell 15 and the buckle 18 of the bottom shell 14 are both located at the corners of the outer shell 1. Through the engagement of the hook 17 and the buckle 18, the bottom shell 14 and the front shell 15 are quickly butted and buckled, improving the assembly efficiency.

[0046] In order to reduce the vibration of the cooling fan during operation, in this embodiment, referring to Figures 1 to 3 , four rubber pads 19 are fixedly arranged on the end faces of the bottom shell 14 and the front shell 15, and the rubber pads 19 are arranged close to the corners of the outer shell 1.

[0047] It can be understood that with such an arrangement, the rubber pads 19 are used to install the cooling fan and are placed between the cooling fan and the computer host case. Through the shock absorption of the rubber pads 19, the vibration transmitted to the case during the operation of the cooling fan is reduced, reducing the vibration noise and improving the user experience. At the same time, the rubber pads 19 are located outside the hook 17 and the buckle 18, thus covering the hook 17 and the buckle 18, making the internal structure invisible on the surface of the outer shell 1 and making the surface of the outer shell 1 more tidy and beautiful.

[0048] In the embodiment of the present application, the cooling fan is installed in the case of the computer host. The air flow generated by the rotation of the fan blade 2 is used for air-cooling the case. The light-emitting component 3 arranged on the side has a certain lighting function. At the same time, by providing a light-emitting groove 11 on the outer side wall of the outer shell 1 and arranging a plurality of light-emitting lamp beads 32 distributed in a matrix arrangement in the light-emitting groove 11, a dot matrix is formed after the plurality of light-emitting lamp beads 32 are lit, so that the dot matrix light-emitting surface 30 on the side of the outer shell 1 forms a dot matrix light-emitting light effect, enabling the cooling fan to have good-looking lights for people to watch during use, decorating the case with the dot matrix light-emitting light effect on the side, making the case more beautiful and enhancing the atmosphere.

[0049] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
