Description

Technical Field

[0001] The present invention relates to the field of heat dissipation equipment, and in particular to a magnetic splicing fan, a fan assembly and a chassis. Background Art

[0002] With the advancement of technology, fans, as a common device for heat dissipation and cooling, are becoming increasingly widespread, with a growing variety of types, including axial-flow fans, centrifugal fans, and mixed-flow fans. Axial-flow fans, a common type of cooling fan, operate by pushing or drawing air along an axis through rotating blades. Air enters and leaves the fan along the same axis. Due to their simplicity, low cost, and high heat dissipation capabilities, axial-flow fans are widely used in the heat dissipation of electronic products such as automobiles, computers, and servers.

[0003] For computing devices with high heat dissipation requirements, such as graphics cards or central processing units (CPUs), multiple cooling fans are often connected side by side to form a whole. For example, at least two cooling fans are connected to achieve better heat dissipation. Therefore, spliced ​​fans have emerged on the market.

[0004] Traditional spliced ​​fans require alignment, sliding, locking and other operations during splicing, which makes the assembly of spliced ​​fans more complicated, reduces the splicing speed, and leads to a poor user experience, which urgently needs to be solved. Utility Model Content

[0005] In order to solve the above problems, the embodiments of the present application provide a magnetic splicing fan, fan group and chassis, which can accurately and reliably position, realize rapid assembly, and optimize the splicing experience.

[0006] To this end, the following technical solutions are adopted in the embodiments of the present application:

[0007] In the first aspect, the present application provides a magnetic splicing fan, comprising: a shell having an installation space inside, the shell having a first splicing surface and a second splicing surface; a pneumatic body installed in the installation space formed by the shell, for providing power for gas flow; a side panel, a plurality of the side panels are arranged around the side of the shell to form a side wall; a magnetic assembly, the magnetic assembly includes a magnetic part and a fixing part, the magnetic part is installed on the first splicing surface, and the fixing part is installed on the second splicing surface; when the first splicing surface and the second splicing surface on the two shells are close to each other, the magnetic part and the fixing part are magnetically attracted to each other to splice and fix the two shells.

[0008] In this embodiment, the shell includes an installation space that accommodates the pneumatic body and provides power for the gas flow. Splicing surfaces are provided on both sides of the shell, namely the first splicing surface and the second splicing surface. The pneumatic body can be driven by an electric motor to promote air flow and form a wind flow. The side panels surround the sides of the shell to form a sturdy structure to ensure the stability of the fan. The magnetic part is installed on the first splicing surface and is usually a strong magnet. The fixing part: is installed on the second splicing surface and is designed to be a magnetic material or metal part that cooperates with the magnetic part. When the two splicing surfaces are close to each other, the magnetic force between the magnetic part and the fixing part achieves automatic alignment and locking, and multiple fans can be spliced ​​together without additional tools or complicated operations. The splicing of traditional fans requires tedious steps such as alignment, sliding, and locking, but the magnetic design eliminates these operations, making the assembly process more intuitive and simple, and improving the user experience. Moreover, the magnetic splicing design in this application allows users to automatically adsorb and fix the two shells when splicing, simply by bringing the two shells close together, which greatly improves the splicing speed and reduces assembly time. This product simplifies the splicing experience and can achieve accurate and reliable positioning as long as the alignment is almost correct.

[0009] As a feasible embodiment, the fixing member includes at least one of a magnet and a metal member; wherein, at least two magnetic members are provided, and the polarities of two adjacent magnetic members facing away from the first splicing surface are opposite.

[0010] As a feasible implementation, the magnetic attraction member may be a neodymium iron boron magnet.

[0011] In this embodiment, high-energy-product neodymium iron boron (NdFeB) magnets provide a strong attraction force, ensuring a secure connection. Furthermore, the polarity of the two adjacent magnetic elements on one side of the first splicing surface is opposite, creating a fool-proof interface design. This polarity design makes it difficult for users to mistakenly connect the two splicing surfaces during splicing, further reducing the possibility of assembly errors.

[0012] As a feasible embodiment, the side panel covers the magnetic component and the fixing component, and a receiving groove is provided on the side of the side panel facing the shell, and the receiving groove is used to accommodate the embedding of the magnetic component or the fixing component.

[0013] In this embodiment, the side panels cover the magnetic and fixing components, forming a protective layer that not only looks good but also prevents dust and other external factors from affecting the performance of internal components. A receiving slot is provided on the side of the side panel facing the housing, with space specifically designed to accommodate the magnetic or fixing components. This design ensures that the magnetic and fixing components are securely embedded and retained within the side panels, preventing them from falling off or shifting during use.

[0014] As an achievable embodiment, a limiting groove is provided on the first splicing surface, and a limiting protrusion is provided on the second splicing surface. The limiting protrusion can be embedded in the limiting groove, and after the limiting protrusion of any one fan is embedded in the limiting groove of the other fan, the movement of the two fans in the first direction and the second direction is limited, wherein the first direction and the second direction are arranged vertically.

[0015] In this embodiment, the limit design effectively prevents the fan from being displaced during operation, ensures the stability and operating efficiency of the equipment, and reduces the risk of failure due to misalignment.

[0016] As a feasible embodiment, the limiting groove is opened on the side panel; the limiting groove and the limiting protrusion are arranged as rectangular strips, and the extension direction of the limiting groove and the limiting protrusion is the first direction of the shell, and the first direction is the thickness direction of the shell.

[0017] In this embodiment, the rectangular design of the retaining groove and retaining protrusion effectively increases the stability of the splicing connection, preventing displacement caused by vibration or impact, thereby improving the overall reliability of the device. The extending direction of the retaining groove and retaining protrusion is consistent with the first direction of the housing, which is the thickness direction of the housing. This design helps provide better support and stability when the fan is connected.

[0018] As a feasible embodiment, the fan also includes an electrical connection component, which includes a spring contact and a passive contact, the passive contact is located on the first splicing surface, and the spring contact is located on the second splicing surface; when the two shells are spliced ​​together, the magnetic part and the fixing part are magnetically attracted and fit together, and the spring contact and the passive contact are electrically connected to each other.

[0019] In this embodiment, magnetic parts and spring contacts are reused in the design to reduce material costs and assembly difficulty. Through the magnetic design, users can quickly and easily splice and electrically connect the fans, reducing installation time. When the fans are spliced, the spring contacts are compressed and contact the passive contacts, thereby achieving electrical connection. The design of the spring contacts ensures that the contacts can maintain good electrical contact even in uneven or vibrating environments, reducing the risk of power outages. This electrical connection method reduces the need for complex connectors or cables, making the design simpler and helping to reduce production costs.

[0020] As a feasible embodiment, the side panels are L-shaped, and the four side panels are arranged around the shell to form the side walls of the shell; when installed on the shell, there is a clearance gap between two adjacent side panels, and the passive contact at the first splicing surface is installed at the clearance gap; the limiting protrusion on the second splicing surface is installed at the clearance gap; and decorative strips are provided at the other two clearance gaps; and a through hole is opened on the side panel located on the second splicing surface for the spring contact to pass through.

[0021] In this embodiment, the clearance gap design between two adjacent side panels allows the side panels to be fine-tuned during installation, ensuring the flexibility of splicing. This gap can avoid deformation caused by temperature changes or physical pressure. The passive contact is arranged in the clearance gap of the second splicing surface, staggered with the limiting protrusion on the first splicing surface, so that the clearance gap is filled while ensuring that the contacts can be stably contacted during splicing to maintain a good electrical connection. Providing decorative strips at the other two clearance gaps not only enhances the aesthetics, but also may play a certain protective role to prevent dust and debris from entering the interior. The side panels on the second splicing surface are provided with perforations for the spring contacts to pass through, ensuring that the spring contacts can stretch freely and contact the passive contacts during splicing. This design ensures the reliability and flexibility of the electrical connection.

[0022] As a feasible embodiment, the peripheral wall of the shell has a preset glue-coated plane, and the inner side wall of the side panel is fixedly connected to the plane by glue.

[0023] As a feasible embodiment, the fan also includes a magnetic power supply, which is provided with a magnetic part and an elastic contact pin; when the magnetic power supply is close to the first splicing surface to the distance where the magnetic part and the magnetic part reach the magnetic attraction effect, the elastic contact pin on the magnetic power supply abuts against the passive contact on the first splicing surface, and the side of the magnetic power supply facing away from the first splicing surface is connected to a power supply device through a wire to provide power and control signals for the fan.

[0024] In this embodiment, when the magnetic power supply is close to the first splicing surface, the magnetic attraction formed between the magnetic member and the magnetic member helps to locate and fix the position of the power supply, simplifying the installation process. When the magnetic power supply is close to the splicing surface, the elastic contact automatically abuts against the passive contact of the first splicing surface, ensuring the stability and reliability of the electrical connection. The back of the magnetic power supply is connected to the power supply device via a wire, forming a transmission path for electrical energy and control signals, allowing the fan to operate efficiently.

[0025] In a second aspect, the present application provides a fan assembly, comprising at least two fans as described in the first aspect, wherein adjacent fans are magnetically spliced ​​together.

[0026] In a third aspect, the present application provides a chassis, comprising: a fan group as described in the second aspect, wherein the fan group is installed on a side panel inside the chassis to dissipate heat from heat-generating components inside the chassis.

[0027] The beneficial effects of the second and third aspects are as described in the first aspect and will not be repeated here.

[0028] In summary, the magnetic splicing fan design effectively solves the cumbersome assembly issues of traditional fans through its innovative splicing mechanism, enhancing user experience and product market competitiveness. This technical solution not only meets user needs functionally, but also excels in aesthetics and affordability, demonstrating broad application prospects.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0047] As described in the background technology, multiple spliced ​​fans in the related technology are generally connected by connectors, which require alignment, sliding, locking and other operations during splicing, resulting in cumbersome assembly of the spliced ​​fans, reduced splicing speed, and poor user experience, which needs to be solved urgently.

[0048] In order to solve the above problems, embodiments of the present application provide a magnetic spliced ​​fan, a fan group formed by splicing multiple magnetic spliced ​​fans, and a chassis having the fan group. Figure 1 A schematic diagram of the three-dimensional structure of two magnetically spliced ​​fans provided in an embodiment of the present application is shown; Figure 2 FIG. 1 shows a schematic structural diagram of a fan assembly provided in an embodiment of the present application. Figure 1 and Figure 2As shown, the fan group includes at least two magnetically spliced ​​fans, such as Figure 1 Two magnetic splicing fans are shown. Figure 2 The cascade assembly of three magnetic splicing fans is shown. The specific number of magnetic splicing fans can be four, five, or more. The number of magnetic splicing fans is selected mainly based on the heat generated by the heat dissipation object. This application does not strictly limit the number of magnetic splicing fans in the fan group. In order to better introduce the magnetic structure between the magnetic splicing fans, Figure 1 The structure of the magnetic splicing of the two magnetic splicing fans is explained.

[0049] Continue reading Figure 1 and Figure 2 The magnetic splicing fan includes a housing 1, an aerodynamic body 2 installed inside the housing 1, and a magnetic assembly installed around the housing 1 (see here for details). Figure 6 ). It can be understood that the pneumatic body 2 is the fan body. The fan body adopts the existing structure, which is mainly a complete product structure that can rotate by itself when powered on, and is used to provide power for gas flow. Specifically, after power is turned on, the fan body can rotate so that the internal airflow flows with the wind, completing the heat dissipation process. It is worth mentioning that the shell 1 is a circular structure with an installation space, thereby providing a channel and guide for the flow of air. That is, the middle part of the shell 1 is a hollow cavity. After the fan body is installed in the installation space of the shell 1, the fan body can rotate stably.

[0050] In order to improve the splicing efficiency of multiple magnetic splicing fans and simplify the splicing connection structure, the shell 1 has a first splicing surface 11 and a second splicing surface 12 for splicing two adjacent magnetic splicing fans. It should be noted that the first splicing surface 11 and the second splicing surface 12 are virtual structures constructed to clearly describe the magnetic splicing structure of the two magnetic splicing fans, and are not physical structures. Specifically, a mounting frame 13 can be extended to the periphery at the upper and lower ends of the shell 1, and the four sides of the mounting frame 13 are rectangular. Exemplarily, the mounting frame 13 and the shell 1 can be integrally formed. In addition, the mounting frame 13 and the shell 1 can also be fixedly connected by at least one method of bonding, screwing or carding, which is not limited in this application. The first splicing surface 11 and the second splicing surface 12 are opposite side walls or adjacent side walls of the outer peripheral side walls of the mounting frame 13, so that the shell 1 can be superimposed on each other in the same direction or different directions to form a building block combination. The user can splice according to actual needs, making the fan combination more convenient (direct placement can be spliced ​​and fixed to each other). For example, when the fan group includes more than three magnetic spliced ​​fans, the magnetic spliced ​​fans can be stacked along one side or at a corner to form a rectangular array, a straight line, a Z shape, or an L shape.

[0051] For the convenience of description, in this embodiment, the first splicing surface 11 and the second splicing surface 12 are two oppositely arranged side walls of the outer peripheral side wall of the mounting frame 13. It should be noted that the plane where the first splicing surface 11 or the second splicing surface 12 is located is tangent to the outer periphery of the shell 1, and the four peripheral sides of the mounting frame 13 are open (see here for details). Figure 6 ) to facilitate the installation of the magnetic assembly and other components of the magnetically assembled fan. Four side panels 3 are arranged around the opening of the mounting frame 13. The four side panels 3 are arranged around the sides of the shell 1 to form side walls, so that the magnetically assembled fan forms a complete whole. It can be understood that the side panels 3 cover the magnetic assembly to protect the magnetic assembly. In addition, the first direction referred to in this application is the thickness direction of the shell 1, the second direction is the length direction of the shell 1, and the third direction is the width direction of the shell 1.

[0052] like Figure 1 and Figure 2 As shown, the magnetic splicing fan also includes an electrical connection component, which includes a spring contact 4 and a passive contact 5. The passive contact 5 is located on the first splicing surface 11, and the spring contact 4 is located on the second splicing surface 12. It should be noted that a through hole 36 for the spring contact 4 to pass through is opened on the side plate 3 located on the second splicing surface 12 (see FIG. Figure 6 ), ensuring that the spring contact 4 can stretch freely and contact the passive contact 5 when spliced. When the two shells 1 are spliced ​​together, the magnetic assembly is magnetically attached and the spring contact 4 and the passive contact 5 are electrically connected to each other, thereby achieving electrical connection between two adjacent magnetically spliced ​​fans.

[0053] Figure 3 A schematic diagram showing the cooperation between the magnetic splicing fan and the magnetic power supply 6 is shown; Figure 4 Schematic diagram of the structure of the magnetic power supply 6 is shown. Figure 3 and Figure 4 As shown, in one embodiment, the magnetic splicing fan further includes a magnetic power supply 6, on which a magnetic member 61 is provided (see Figure 5 ) and elastic contact pin 62; when the magnetic power supply 6 approaches the first splicing surface 11 until the magnetic member 61 and the magnetic assembly reach the distance for magnetic attraction, the elastic contact pin 62 on the magnetic power supply 6 abuts against the passive contact 5 on the first splicing surface 11 to achieve electrical connection. Optionally, the side of the magnetic power supply 6 facing away from the first splicing surface 11 is connected to a power supply device (not shown) via a wire 63 to provide power and control signals to the fan, so that the fan group composed of multiple magnetic splicing fans can operate normally.

[0054] Based on the above content, the magnetic assembly, magnetic power supply 6 and side panel 3 of the magnetic splicing fan are described in detail below.

[0055] Figure 5The figure shows the exploded structural front view of the magnetic spliced ​​fan and the magnetic power supply 6; Figure 6 The figure shows a perspective view of the exploded structure of the magnetic splicing fan and the magnetic power supply 6. Figure 5 and Figure 6 As shown, the magnetic attraction assembly includes a magnetic member 7 and a fixing member 8, the magnetic member 7 is installed on the first splicing surface 11, and the fixing member 8 is installed on the second splicing surface 12; when the first splicing surface 11 and the second splicing surface 12 on the two shells 1 are close to each other, the magnetic member 7 and the fixing member 8 are magnetically attracted to each other to splice and fix the two shells 1. In one embodiment, the fixing member 8 is a metal member. In another embodiment, the fixing member 8 can also be a magnet member, as long as the magnetic member 7 and the fixing member 8 can be magnetically fixed. For example, when the fixing member 8 is a magnet member, the material of the magnet member and the magnetic member 7 are both neodymium iron boron magnets, and the use of neodymium iron boron (NdFeB) magnets with high magnetic energy product can provide strong attraction to ensure stable splicing. Optionally, in order to further improve the magnetic attraction stability between the two shells 1, at least two magnetic members 7 are provided, and the two magnetic members 7 are respectively located on opposite sides of the first splicing surface 11. Correspondingly, at least two fixing members 8 are also provided on the second splicing surface 12. In other embodiments, the first splicing surface 11 may also be respectively provided with a magnetic part 7 and a fixing part 8, and correspondingly, the second splicing surface 12 may also be respectively provided with a magnetic part 7 and a fixing part 8. The magnetic parts 7 and the fixing parts 8 on the first splicing surface 11 and the second splicing surface 12 correspond one to one. As long as the two shells 1 can be magnetically fixed, this application does not limit the position and number of the magnetic parts 7 and the fixing parts 8.

[0056] Figure 7 The exploded structure of the magnetic splicing fan and the magnetic power supply 6 is shown in another perspective. Figure 6 and Figure 7 As shown, in this embodiment, two magnetic members 7 and two fixing members 8 are respectively provided, and both the magnetic members 7 and the fixing members 8 are long magnets with square cross-sections. In this way, the two ends of the length of the magnetic member 7 have different polarities. It is worth mentioning that the polarities of the two magnetic members 7 on the first splicing surface 11 facing away from the first splicing surface 11 are opposite, and correspondingly, the polarity of the fixing member 8 on the second splicing surface 12 is opposite to that of the corresponding magnetic member 7, so that the two shells 1 can be quickly spliced ​​together when they are assembled correctly. When the two shells 1 are not docked correctly, for example, when the wind directions of the two fans are docked in opposite directions, the magnetic member 7 and the fixing member 8 have the same polarity and repel each other, making it difficult for the user to incorrectly connect the two splicing surfaces when splicing, further reducing the possibility of assembly errors.

[0057] Exemplarily, in this embodiment, the side panels 3 are L-shaped. It should be noted that when the four side panels 3 are arranged around the shell 1 to form the side walls of the shell 1, there is a clearance gap 31 between two adjacent side panels 3, which can avoid deformation caused by temperature changes or physical pressure. In order to make the fan more beautiful as a whole, decorative strips 32 are installed at the four clearance gaps 31. The decorative strips 32 can also play a certain protective role, preventing dust and debris from entering the inside of the fan. It is worth mentioning that the side panels 3 can be bonded to the shell 1 by any of bonding, screwing or clamping. For example, the top of the circular arc is flattened at one side wall of the mounting frame 13 located on the outer periphery of the shell 1 to obtain a preset glue coating plane 9, glue is applied on the preset glue coating plane 9, and then the side panels 3 are bonded to the preset glue coating plane 9 of the mounting frame 13 by glue, and then the side panels 3 are installed on the shell 1. Alternatively, a slot is provided on the housing 1, and a buckle is installed at a corresponding position on the side panel 3. The side panel 3 is mounted on the housing 1 through the engagement of the buckle and the slot. Alternatively, the side panel 3 can be fixed to the mounting frame 13 of the housing 1 by screws, which is not limited in this application.

[0058] Optionally, when the side panel 3 covers the magnetic member 7 and the fixing member 8, a receiving groove 33 is provided on the side of the side panel 3 facing the housing 1. The receiving groove 33 is used to accommodate the insertion of the magnetic member 7 or the fixing member 8. To ensure a more stable fixation of the magnetic member 7 and the fixing member 8, after the magnetic member 7 and the fixing member 8 are inserted into the receiving groove 33, the magnetic member 7 / fixing member 8 are bonded to the receiving groove 33 using glue.

[0059] Continue reading Figure 6 and Figure 7 To ensure more stable magnetic attraction between the two magnetically joined fans, a limiting groove 111 is provided on the first joining surface 11, and a limiting protrusion 121 is provided on the second joining surface 12. The limiting protrusion 121 can be embedded in the limiting groove 111. When the limiting protrusion 121 of one fan is embedded in the limiting groove 111 of the other fan, the movement of the two fans in a first direction and a second direction is restricted. The first direction and the second direction are arranged perpendicularly. In this way, the cooperation between the limiting protrusion 121 and the limiting groove 111 can form a limit between the housings 1, preventing the magnetic element 7 and the fixing element 8 from sliding when subjected to external forces, thereby making the mutual attraction between the two housings 1 more stable. At the same time, the cooperation between the limiting groove 111 and the limiting protrusion 121 enables precise docking of the two fans when spliced ​​together, and can also form a fool-proof design in conjunction with the magnetic element 7. For example, when the first joining surfaces 11 of the two fans are spliced ​​together, due to magnetic repulsion and the limiting, the fans cannot be spliced ​​together, thus providing protection. The limiting protrusion 121 and the limiting groove 111 can be interchanged according to actual conditions.

[0060] For example, in this embodiment, the limiting groove 111 is provided on the side panel 3, and the limiting protrusion 121 is installed on the decorative strip 32 of the clearance gap 31; the limiting groove 111 and the limiting protrusion 121 are arranged as rectangular strips, and the extending direction of the limiting groove 111 and the limiting protrusion 121 is the first direction of the shell 1, and the first direction is the thickness direction of the shell 1. While achieving the limiting effect, the force support point between the shells 1 is more stable, avoiding the force being applied to a single position. In some embodiments, the limiting method is not limited to the concave and convex physical structure of the strip described in this embodiment, and other forms such as snaps can also have a limiting effect, and this application does not limit it here.

[0063] Figure 8The schematic diagram of the working principle of the magnetic splicing fan of the present application is shown as follows: Figure 8 As shown, the magnetic power supply 6 is adsorbed on the passive contact 5 through the magnetic part 7 and the circular magnet, and after its own spring contact 4 is electrically connected to the passive contact 5, it serves as an external power supply to the fan, and the adjacent magnetic splicing fans are magnetically attracted by the magnetic part 7 and the fixing part 8, and are also electrically connected through the spring contact 4 and the passive contact 5, so that the fan group can work normally. The design of the magnetic splicing fan has an innovative splicing mechanism. Compared with other splicing fans, it has a simple structure, convenient and simple splicing, and is reliable. It effectively solves the problem of cumbersome assembly of traditional fans, and can accurately and reliably position, achieve rapid assembly, and optimize the splicing experience. In addition, the interface of the magnetic splicing fan of the present application is foolproof. When the connection is incorrect, the magnets repel each other and the limit cannot be spliced, which protects the fan and improves the user experience and the market competitiveness of the product. The design reuses magnets and spring contacts 4 to reduce material costs and assembly difficulty. In short, this technical solution not only meets the needs of users in terms of function, but also performs well in terms of aesthetics and economy, and has broad application prospects.
