Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically to a magnetically attached cooling fan that can be spliced ​​and positioned. Background Technology

[0002] In everyday electronic products, such as desktop computers and televisions, the main control board and other electrical components usually generate a lot of heat during use. Specifically, the heat dissipation process mainly relies on cooling fans to dissipate the internal heat to the outside, thereby accelerating the heat dissipation process.

[0003] Currently, to improve heat dissipation efficiency, many interconnectable cooling fans have appeared on the market. The interconnected structure of a cooling fan mainly refers to the connection or assembly method between individual cooling fans, ensuring stable operation and effective heat dissipation. Connecting multiple cooling fans is primarily to enhance heat dissipation and increase the heat dissipation area.

[0004] Authorization announcement number CN219809171U discloses a magnetic cooling fan, specifically comprising a mounting frame and a fan body mounted on the mounting frame; the mounting frame has a first sidewall and a second sidewall disposed opposite to each other, a contact pin seat mounted on the first sidewall, and a conductive seat matched with the contact pin seat mounted on the second sidewall; two first magnets are spaced apart on the first sidewall, and two second magnets are spaced apart on the second sidewall corresponding to the two first magnets; the fan body also includes a wire connecting the contact pin seat, the fan body, and the conductive seat. The number of cooling fans is at least two, with the first magnets and second magnets on two adjacent cooling fans attracting each other, and the contact pin seats and conductive seats on two adjacent cooling fans abutting and adhering to each other.

[0005] However, the aforementioned magnetic cooling fan also has some drawbacks. For example, the stability of the two cooling fans after assembly is not good enough, which may cause horizontal and vertical misalignment of the mating surfaces between the two fans. In addition, at least one end face of the first and second magnets on the mounting frame is exposed, which affects the overall aesthetics of the mounting frame and does not adequately protect the magnets.

[0006] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a magnetically attached cooling fan that can be spliced ​​and positioned, which can prevent horizontal and vertical misalignment of the mating surfaces of two cooling fan bodies after splicing; in addition, it can not only protect the magnet, but also make the overall appearance of the casing more aesthetically pleasing.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A modular, positionable magnetic cooling fan includes a cooling fan body. The cooling fan body includes a hollow housing, a fan installed in the middle of the housing, a contact pin seat and a conductive seat respectively installed on a first sidewall and a second sidewall opposite to each other on the housing and electrically connected to the fan, a first magnet and a second magnet respectively embedded in the first sidewall and the second sidewall, and a first cover and a second cover respectively installed on the first sidewall and the second sidewall. The first cover covers the first magnet so that the first magnet is hidden inside the housing. The second cover is placed over the second magnet, concealing it within the housing. At least two evenly distributed alignment protrusions are provided on the upper and lower sides of the first sidewall. At least two evenly distributed alignment grooves, corresponding to the alignment protrusions, are provided on the upper and lower sides of the second sidewall. The upper alignment grooves open outwards and upwards, while the lower alignment grooves open outwards and downwards, allowing for easy and direct observation of the alignment process between the alignment protrusions and grooves during the assembly of the two cooling fan bodies. This design ensures that the mating surfaces of the two cooling fan bodies will not misalign horizontally or vertically after assembly. Furthermore, it prevents the two magnets from being exposed on the housing, protecting them and enhancing the overall aesthetics of the housing.

[0010] Furthermore, the width of both the alignment protrusion and the alignment groove gradually narrows from the inner end to the outer end. This design allows the alignment protrusion to be inserted into the alignment groove more conveniently and smoothly.

[0011] Furthermore, the outer end face of the alignment bump is a convex arc-shaped surface, and the sidewall shape of the alignment groove matches the shape of the alignment bump. This design further improves the alignment speed, facilitating the splicing of two cooling fan bodies.

[0012] Furthermore, the bottom surfaces of the alignment protrusion and the alignment groove are both mutually mating planes or inclined surfaces to ensure the stability of the alignment protrusion and the alignment groove after they are interlocked.

[0013] Furthermore, the first cap is secured to the first sidewall; the second cap is secured to the second sidewall.

[0014] Furthermore, a first locking hole and a second locking hole are respectively provided on the first sidewall and the second sidewall; the first magnet and the second magnet are respectively located in the first locking hole and the second locking hole; a first slot and a second slot are respectively provided on the four sides of the first locking hole and the four sides of the second locking hole; the four sides of the first cover are matched and locked in the first slot; the four sides of the second cover are matched and locked in the second slot. This arrangement enhances the positioning stability of the first and second covers while also strengthening the protection of the first and second magnets to a certain extent.

[0015] Furthermore, an embedding groove is provided on the back of both the first and second caps; the first magnet and the second magnet are correspondingly embedded in the two embedding grooves. This arrangement allows for greater stability between the first and second magnets.

[0016] Furthermore, the cooling fan body also includes a light strip installed in the housing that can emit light outwards; the light strip is electrically connected to the contact pin seat and the conductive seat respectively.

[0017] Furthermore, the housing includes light-transmitting plates located on both sides thereon, so that the light emitted by the light strip can be emitted outward.

[0018] Furthermore, the number of heat sink bodies is at least two that cooperate with each other; the first magnet and the second magnet on two adjacent heat sink bodies attract each other, each of the alignment protrusions and the corresponding alignment grooves are matched and inserted into each other, and the contact pin seat and the conductive seat abut against each other.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention utilizes corresponding alignment protrusions and alignment grooves to improve the stability between the two, preventing horizontal and vertical misalignment of the mating surfaces of the two cooling fan bodies after splicing. Moreover, since the upper alignment groove has an upward opening and the lower alignment groove has a downward opening, it is convenient for people to visually observe the insertion and alignment process of the alignment protrusion and alignment groove, making the insertion easier.

[0021] In addition, since the first magnet and the second magnet are respectively installed on the first side wall and the second side wall of the housing, and are then covered by the first cover and the second cover respectively, the first magnet and the second magnet will not be exposed on the housing. This not only protects the two magnets, but also makes the overall appearance of the housing more aesthetically pleasing. Attached Figure Description

[0031] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0032] like Figures 1-5 As shown, a magnetically attached cooling fan that can be assembled and positioned includes a cooling fan body 1.

[0033] like Figures 1-5As shown, the cooling fan body 1 includes a hollow shell 2, a fan 3 installed in the middle of the shell 2, contact pin seats 4 and conductive seats 5 respectively installed on the first sidewall 21 and the second sidewall 22 opposite to each other on the shell 2 and electrically connected to the fan 3, a first magnet 6 and a second magnet 7 respectively embedded in the first sidewall 21 and the second sidewall 22, and a first cover 8 and a second cover 9 respectively installed on the first sidewall 21 and the second sidewall 22; the first cover 8 covers the first magnet 6 so that the first magnet 6 is hidden inside the shell 2; the second cover 9 covers the second magnet 7 so that the second magnet 7 is hidden inside the shell 2. Therefore, the arrangement of the first cover 8 and the second cover 9 can conveniently cover the first magnet 6 and the second magnet 7 to avoid the magnets being exposed on the shell 2. In this way, not only can the magnets be protected, but the overall appearance of the shell 2 is also more aesthetically pleasing. It should also be noted that the first magnet 6 and the second magnet 7 can both be magnets, or one can be a magnet and the other can be a metal block that can magnetically attract and cooperate with the magnet.

[0034] like Figures 1-5 As shown, at least two evenly distributed alignment protrusions 10 are respectively provided on the upper and lower sides of the first sidewall 21; at least two evenly distributed alignment grooves 11 corresponding to the alignment protrusions 10 are respectively provided on the upper and lower sides of the second sidewall 22. Therefore, after providing alignment protrusions 10 and alignment grooves 11 on the housing 2, accurate alignment can be achieved by utilizing the cooperation of alignment protrusions 10 and alignment grooves 11 when the two cooling fan bodies 1 are to be spliced ​​together. Specifically, the upper alignment groove 11 opens outward and upward respectively, while the lower alignment groove 11 opens outward and downward respectively. This allows the two cooling fan bodies 1 to be positioned by the alignment protrusions 10 and the alignment grooves 11 after assembly, as they are inserted into the corresponding alignment grooves 11. The upward and downward openings of the alignment grooves 11 restrict the horizontal and vertical movement of the alignment protrusions 10, preventing horizontal and vertical misalignment between the two cooling fan bodies 1 and ensuring their stability. Furthermore, the upward and downward openings of the alignment grooves 11 facilitate visual observation of the alignment process between the alignment protrusions 10 and the alignment grooves 11, making the insertion easier.

[0035] In summary, this utility model utilizes corresponding alignment protrusions 10 and alignment grooves 11 to improve the stability between the two components, preventing horizontal and vertical misalignment of the mating surfaces of the two cooling fan bodies 1 after assembly. Furthermore, since the upper alignment groove 11 has an upward-facing opening, and the lower alignment groove 11 has a downward-facing opening, the insertion and alignment process of the alignment protrusions 10 and alignment grooves 11 can be easily observed from the outside, making the insertion easier. Additionally, since the first magnet 6 and the second magnet 7 are respectively installed on the first sidewall 21 and the second sidewall 22 of the housing 2, and then covered by the first cover 8 and the second cover 9, the first magnet 6 and the second magnet 7 are not exposed on the housing 2. This not only protects the two magnets but also makes the overall appearance of the housing 2 more aesthetically pleasing.

[0036] like Figures 1-4 As shown, in this embodiment, the width of both the alignment protrusion 10 and the alignment groove 11 gradually narrows from the inner end to the outer end, which makes it easier and smoother for the alignment protrusion 10 to be inserted into the alignment groove 11, thereby improving the alignment speed.

[0037] like Figures 1-4 As shown, in order to further improve the alignment speed and facilitate the splicing of the two cooling fan bodies 1, the outer end face of the alignment bump 10 is an outwardly convex arc surface 101, and the side wall shape of the alignment groove 11 matches the shape of the alignment bump 10.

[0038] However, those skilled in the art should know that, if necessary, the shape of the alignment bump 10 can also be set to a cylinder, a cube, or a cuboid, etc., and the shape of the alignment groove 11 only needs to be set to match the shape of the alignment bump 10, which will not be elaborated further here.

[0039] like Figures 1-4 As shown, in this embodiment, the first cover 8 is secured to the first sidewall 21; the second cover 9 is secured to the second sidewall 22. Specifically, a first locking hole 211 and a second locking hole 221 are respectively provided on the first sidewall 21 and the second sidewall 22; the first magnet 6 and the second magnet 7 are respectively located in the first locking hole 211 and the second locking hole 221; a first locking groove 212 and a second locking groove 222 are respectively provided on the four sides of the first locking hole 211 and the four sides of the second locking hole 221; the first cover 8 is secured in the first locking groove 212; the second cover 9 is secured in the second locking groove 222. Therefore, the above arrangement can enhance the positioning stability of the first cover 8 and the second cover 9, and also enhance the protection of the first magnet 6 and the second magnet 7 to a certain extent.

[0040] like Figure 3and Figure 4 As shown, in this embodiment, an embedding groove 12 is provided on the back of the first cover 8 and the second cover 9 respectively; the first magnet 6 and the second magnet 7 are correspondingly embedded in the two embedding grooves 12. Therefore, by providing the embedding grooves 12, the stability of the first magnet 6 and the second magnet 7 can also be guaranteed.

[0041] like Figure 5 As shown, in this embodiment, the cooling fan body 1 also includes a light strip 13 installed in the housing 2 and capable of emitting light outwards; the light strip 13 is electrically connected to the contact pin seat 4 and the conductive seat 5 respectively. Therefore, by setting the light strip 13, it can be used to provide colorful lighting to provide a better atmosphere.

[0042] Specifically, the light strip 13 is arranged around the fan 3, which allows for better light emission.

[0043] like Figure 1 As shown, in this embodiment, the housing 2 includes light-transmitting plates 14 located on both sides thereon, so that the light emitted from the light strip 13 can be emitted outward. However, those skilled in the art should know that the light-transmitting plates 14 can also be set in other positions on the housing 2, which will not be exemplified here.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom surfaces of the alignment protrusion 10 and the alignment groove 11 are mutually mating planes to ensure the stability of the two after insertion.

[0045] like Figure 7 As shown, in other embodiments, the bottom surfaces of the alignment protrusion 10 and the alignment groove 11 can also be mutually cooperating inclined surfaces 15. Under this design, the stability of the alignment protrusion 10 and the alignment groove 11 after they are engaged can also be guaranteed.

[0046] like Figure 6 As shown, in one specific embodiment, the number of heat sink bodies is at least two that cooperate with each other; the first magnet 6 and the second magnet 7 on two adjacent heat sink bodies 1 attract each other, each alignment protrusion 10 and the corresponding alignment groove 11 are matched and inserted into each other, and the contact pin seat 4 and the conductive seat 5 are in contact and adhered.

[0047] In one specific embodiment, the fan 3 includes a motor mounted on the housing 2 and fan blades mounted on the output shaft of the motor. Since the structure of the fan 3 is existing technology, it will not be described in detail here.

[0048] In addition, since the structure and principle of the contact pin seat 4 and the conductive seat 5 are existing technologies, they will not be described in detail here.

[0049] The following describes the working principle of the two heat sink bodies of this utility model when they are joined together:

[0050] First, align the contact pin seats 4 and conductive seats 5 in the two cooling fan bodies 1, and align the alignment protrusions 10 and alignment grooves 11. Next, push the two cooling fan bodies 1 closer together, making the contact pin seats 4 and conductive seats 5 abut and fit together. Simultaneously, each alignment protrusion 10 and its corresponding alignment groove 11 is inserted into the other. Next, after each alignment protrusion 10 and its corresponding alignment groove 11 is inserted into the other, the first magnet 6 and the second magnet 7 are also attracted to each other, thus achieving a rapid positioning and splicing effect for the two cooling fan bodies 1. The above steps complete the splicing and stacking of two cooling fan bodies 1. If it is necessary to splice other cooling fan bodies 1, simply repeat the above steps; they will not be elaborated further here.

[0051] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
