Description

Technical Field

[0001] The present invention relates to the field of heat dissipation equipment, and in particular to a fan and electronic equipment with multi-faceted magnetic attraction. 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] During use, existing fans sometimes need to be connected together to form a fan system. For example, when cooling hardware in computing devices that have high heat dissipation requirements, such as graphics cards or central processing units (CPUs) that generate a lot of heat, multiple cooling fans are usually connected side by side as a whole to cool the graphics card or CPU in order to increase the fan's heat dissipation capacity.

[0004] However, conventional fans require additional mechanisms to securely connect adjacent fans together when clustering. This type of fan requires alignment, sliding, and locking. Alternatively, fans can be secured using a single-sided magnetic method, but this method only achieves one-dimensional magnetic clustering. In some scenarios with higher heat dissipation requirements, a third clustering structure is sometimes required to securely connect the fans together, which is inconvenient to operate and expensive to use. In other words, existing fans cannot be quickly installed when users need to expand the number of fans, causing inconvenience to users. Utility Model Content

[0005] In order to solve the above problems, an embodiment of the present application provides a fan and an electronic device with multi-sided magnetic attraction. The fan has multiple splicing surfaces with magnetic attraction, and can use a multi-sided magnetic attraction method to achieve multi-dimensional magnetic connection between multiple fans. It is simple to operate, can accurately and reliably position, achieve 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 fan with multi-sided magnetic attraction, comprising: a frame, the frame having an airflow channel; a fan body, installed in the airflow channel of the frame, for providing power for the gas flow to generate airflow; and a structural member, at least two structural members with magnetic attraction are installed on the frame, the structural members provide magnetic attraction for at least two adjacent side surfaces of the frame, so that the frame has at least two splicing surfaces with magnetic attraction; when the splicing surface is close to the splicing surface on the other frame to the distance where the structural members on the two splicing surfaces form a magnetic attraction, the two adjacent fans are spliced.

[0008] In this embodiment, traditional fan splicing methods generally only support connection in one direction, such as through sliding, locking, or single-sided magnetic attraction. This solution uses multiple magnetic structural components to provide magnetic attraction on multiple sides, allowing fans to be spliced ​​in multiple dimensions. When multiple fans need to be spliced ​​together, simply place the splicing surface of one fan close to the splicing surface of another fan, and the magnetic structural components will automatically attract each other through magnetic force, thus completing the splicing. This process does not require additional tools or complex operations; simple alignment is all that is needed to achieve connection. Multiple magnetic surfaces can support splicing in multiple directions. For example, two fans can be docked in multiple directions such as up, down, left, and right, rather than being limited to one direction. This provides more possibilities for flexible fan combination and expansion. Whether parallel splicing (horizontally, vertically) or vertical splicing, simple and quick connection can be achieved, greatly improving the flexibility of splicing. Through magnetic attraction, fans can be easily adsorbed together without the use of additional fixing mechanisms (such as screws, locking devices, sliding structures, etc.). This design reduces the number of installation steps, avoids tedious alignment and sliding operations, greatly simplifies the difficulty of fan assembly and disassembly, and reduces the manufacturing cost and structural complexity of the product. Moreover, during the splicing process, the magnetic force not only plays a connecting role, but also ensures the accuracy of the splicing, avoids splicing deviation, and enhances the stability of the fan splicing. This allows the fan to be quickly installed in a very short time, and the splicing process is simpler, without the need for complicated alignment, locking, sliding and other steps. The magnetic suction method provides a strong attraction, which can ensure that the spliced ​​fans are accurately and reliably connected together. This avoids problems such as loosening and falling off of the fan due to loose splicing, and improves the overall stability and reliability of the fan system.

[0009] As a feasible implementation, the structural component includes a magnet component and a magnetic induction component, wherein there is a magnetic attraction between the magnet component and the magnetic induction component.

[0010] In this embodiment, the magnetic parts are usually composed of permanent magnets (such as rare earth neodymium iron boron magnets), which can generate a stable magnetic field and have strong magnetic force. They are installed on the splicing surface of the fan frame and serve as a key magnetic source for connecting other fans or structural parts. The magnetic sensitive part is a material or component that can respond to an external magnetic field, usually a ferromagnetic material such as iron, steel or alloy. These materials do not generate a magnetic field themselves, but when they are close to the magnetic part, they will be attracted by the magnetic field generated by the magnetic part, thereby forming a magnetic connection with the magnetic part. When the fans are spliced, once the splicing surfaces of the fans are aligned, the magnetic sensitive parts will be quickly adsorbed by the magnet parts to achieve fast and accurate splicing. Through the interaction of multiple magnet parts and magnetic sensitive parts, a multi-dimensional splicing method can be achieved.

[0011] As a feasible embodiment, the magnet part includes any one of a neodymium iron boron magnet, an alnico magnet and a ferrite magnet; and / or the magnetic sensitive part is a metal part, and the metal part includes any one of iron, nickel, cobalt and an iron-based alloy.

[0012] In this embodiment, suitable magnet and magnetic induction component materials can be selected according to design requirements to achieve the best magnetic connection effect while taking into account cost, durability and stability.

[0013] As a feasible embodiment, the structural member is a magnet member, the magnet member is arranged in a long strip shape, and the length direction of the magnet member is the first direction of the shell, and the first direction is the thickness direction of the shell; the magnet member has an N pole and an S pole distributed along its own length direction, and the magnet member is installed on the splicing surface on one side of the shell, and the polarities of the two magnet members that are magnetically attracted to each other are opposite.

[0014] In this embodiment, the magnet is in the shape of an elongated strip, and its length direction is consistent with the thickness direction of the shell. That is, the length of the magnet is parallel to the contact surface of the shell splicing surface, so that the magnet can be expanded in this direction during the installation process, thereby providing a larger contact area and magnetic attraction. The magnet has a clear distribution of north and south poles along its length. Specifically, each part of the magnet has a north pole (north pole) and a south pole (south pole) region, and when it is installed, the polarity of the two magnets that are attracted to each other is opposite, that is, the north pole and the south pole attract each other. The polarity design of the magnet ensures that when the two magnets contact on the splicing surface, their north poles and south poles attract each other, thereby generating a strong attraction, ensuring the stability and firmness of the connection. Moreover, the polarity design can also constitute a fool-proof design. When two fans are connected incorrectly, due to the polarity design of the magnet, it is difficult for the user to incorrectly connect the two splicing surfaces together when splicing, further reducing the possibility of assembly errors.

[0015] As a feasible implementation, two ends of the magnet member respectively abut against two joint surfaces of the shell located in the first direction.

[0016] In this embodiment, the two ends of the magnet member respectively abut against the two splicing surfaces of the housing in the first direction, so that the air inlet and air outlet surfaces of the fan also have a certain degree of magnetism. This not only allows the two fans to be stacked together, but also allows the air inlet or air outlet surface of the fan to be attracted to an iron or magnetic fixing frame, thereby facilitating the installation of the fan. In this way, after the fans are assembled and spliced ​​together, they are placed on the component to be cooled, such as the front panel of the chassis. The bottom surface of the fan is magnetically attracted to the metal of the chassis front panel through magnetic attraction, generating magnetic attraction to achieve a weak fixation of the fan. The fan can then be fixed to the chassis front panel with screws as needed for a stronger fixation.

[0017] As a feasible implementation, both ends of the magnet are circular or rectangular.

[0018] In this embodiment, according to the requirements of the actual application, selecting a suitable magnet shape (circular or rectangular) will help optimize the connection effect, improve stability and reduce costs.

[0019] As an achievable embodiment, at least one positioning protrusion is provided on any one of the splicing surfaces of the frame, and a positioning groove cooperating with the positioning protrusion is provided on the other splicing surface of the frame, the positioning protrusion can be embedded in the positioning groove, and after the positioning protrusion of any one fan is embedded in the positioning groove of the other fan, the movement of the two fans in the first direction and the second direction is restricted, wherein the first direction and the second direction are arranged vertically.

[0020] In this embodiment, the positioning bumps and grooves act as a foolproof mechanism, providing a simple and effective way to precisely align the fans. Because the positioning bumps can only fit within specific grooves, this structure ensures consistent fan alignment, preventing incorrect fan connection due to misaligned surfaces. Furthermore, by embedding the positioning bumps within the grooves, the two fans can be effectively prevented from shifting relative to each other due to external forces or vibration during use, enhancing the stability of the connection.

[0021] As a feasible embodiment, one end of the frame along the first direction is an open structure, and a limiting groove for installing a structural member is provided inside the opening structure of the frame; a rubber cover for closing its own opening is installed on the frame, and a shock-absorbing rubber pad is provided on the side of the rubber cover facing away from the frame.

[0022] In this embodiment, the openings at both ends of the frame are structurally designed to allow the installation of various external components or structural parts. The limiting groove is located inside the opening of the frame and is mainly used to position and fix the structural parts. The structural parts are kept stable by inserting into the limiting grooves to prevent them from being displaced or loosened during use. The limiting groove design can ensure the precise position of the installation parts, so that the entire frame and the installed structural parts remain fixed, and reduce position deviation or loosening caused by external impact or vibration. The rubber cover is used to close the opening of the frame. The rubber cover can not only prevent external dust and impurities from entering the frame, but also provide sealing protection to a certain extent to prevent internal components from being affected by the external environment. A shock-absorbing rubber pad is installed on the back of the rubber cover to reduce the impact of external vibration, impact or vibration transmitted to the inside of the frame.

[0023] As a feasible embodiment, a first connector is provided on any one of the splicing surfaces of the frame, and a second connector electrically connected to the first connector is provided on the other splicing surface of the frame; when the two fans are spliced ​​together, the splicing surfaces of the two shells are magnetically attached, and the first connector and the second connector are electrically connected to each other.

[0024] In this embodiment, when the two frames are joined, the first and second connectors form an electrical connection through physical contact, ensuring the flow of electrical signals or current. This electrical connection ensures that the electronic components in the two fan systems can share power or data channels, making it suitable for connecting multiple devices in series, such as connecting the power supply or control system of the fans. Furthermore, this electrical connection method reduces the need for complex connectors or cables, making the design simpler and helping to reduce production costs. It also avoids the risk of failure caused by cluttered wiring.

[0025] In a second aspect, the present application provides an electronic device comprising: at least one fan as described in the first aspect. The fan is mounted on the electronic device and is used to dissipate heat from heat-generating components within the electronic device. Because the electronic device utilizes the fan described in the first aspect, the electronic device has an efficient, stable, and flexible fan cooling system, thereby improving the electronic device's heat dissipation capabilities and optimizing its operating efficiency.

[0026] In summary, the fan with multi-faceted magnetic attraction of the present application has at least the following advantages:

[0027] 1. The integrated splicing is simple and convenient. No additional third integrated structure is required to splice the fan bodies together. When the two fan bodies are close to each other, they will be adsorbed together. The four NS matched magnetic surfaces have anti-fool limiters, and the connection is stable and the installation will not be misplaced.

[0028] 2. The fan has multi-surface magnetic attraction force, which can realize two-dimensional flexible cluster connection and splicing between fans, and can be adsorbed to the iron or magnetic fixing frame on the air inlet surface and the air outlet surface; for example, the magnet is installed close to the corner of the fan, which realizes effective magnetic attraction field on the bottom surface, the top surface and the two side surfaces, realizes two-dimensional splicing between multiple fans, and the top surface or the bottom surface of the fan is magnetically attracted and fixed to the cabinet body or the cold row with a magnetic sensing part;

[0029] 3. The connector is used for electrical connection, so that the fans are connected in cluster and look neat, and the excessive lines are avoided. BRIEF DESCRIPTION OF DRAWINGS

[0046] As described in the background technology, conventional fan clustering requires additional mechanisms to secure adjacent fans together. This type of fan assembly requires alignment, sliding, and locking. Alternatively, fans can be secured using a single-sided magnetic connection, but this method only achieves one-dimensional magnetic connection. In some scenarios with more demanding heat dissipation requirements, a third clustering structure is sometimes required to secure the fans together. This is inconvenient and expensive, and urgently needs to be addressed.

[0047] In order to solve the above problems, the embodiments of the present application provide a fan and an electronic device with multi-sided magnetic attraction. The technical solution of "a fan with multi-sided magnetic attraction" provided in this application aims to achieve multi-dimensional (for example, two-dimensional) magnetic connection of multiple fans by adding multiple structural parts with magnetic attraction to the fan frame. The core of this solution is to add splicing surfaces with magnetic attraction so that adjacent fans can be quickly and accurately connected in multiple directions, and the installation operation of the fan is simplified. Afterwards, multiple fans with multi-sided magnetic attraction are connected and installed in an electronic device to dissipate heat for electrical components such as the main control board inside the electronic device, thereby maintaining good heat dissipation inside the electronic product and ensuring the service life of the internal electrical components.

[0048] Figure 1 A schematic diagram of the three-dimensional structure of two fans with multi-faceted magnetic attraction provided by an embodiment of the present application is shown; Figure 2 The figure shows the schematic diagram of the polarity distribution of the magnets in the fan. Figure 1 and Figure 2 As shown, the number of fans with multi-sided magnetic attraction can be two, three, four, five, or more. The number of fans with multi-sided magnetic attraction is selected mainly according to the heat generated by the heat dissipation object. This application does not strictly limit the number of fans with multi-sided magnetic attraction included in the electronic device. In order to better introduce the magnetic attraction matching structure between fans with multi-sided magnetic attraction, Figure 1 It is worth mentioning that the first direction in the following text is the thickness direction of the frame 1, the second direction is the length direction of the frame 1, and the third direction is the width direction of the frame 1.

[0049] Continue reading Figure 1 and Figure 2 , a fan with multi-faceted magnetic attraction includes a frame 1, a fan main body 2 installed inside the frame 1, and a structural member 3 with magnetic attraction installed around the frame 1. It can be understood that the fan main body 2 is responsible for generating airflow to achieve the heat dissipation function. The frame 1 defines the shape of the fan and the internal wind flow channel. For example, the fan main body 2 adopts an 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, the fan main body 2 includes blades and a motor. After power is turned on, the motor in the fan main body 2 can drive the blades to rotate so that the internal airflow flows, and the heat dissipation process is completed after the wind flow is generated. It is worth mentioning that the frame 1 is a rectangular frame 1, and the interior of the frame 1 is a circular ring structure with an installation space. The circular ring structure is the wind flow channel, which provides a channel and guide for the flow of wind. The two ends of the wind flow channel are the air inlet and outlet of the fan respectively. After the fan body 2 is installed in the air flow channel of the frame 1, the fan body 2 can rotate stably so that the air flow flows from the air inlet surface through the air flow channel of the fan and then flows out of the fan from the air outlet surface.

[0050] In some embodiments, at least two structural members 3 with magnetic attraction are installed on the frame 1, and the structural members 3 provide magnetic attraction for at least two adjacent side surfaces of the frame 1, so that the frame 1 has at least two splicing surfaces 4 with magnetic attraction; when the splicing surface 4 is close to the splicing surface 4 on the other frame 1 to the distance where the structural members 3 on the two splicing surfaces 4 form a magnetic attraction, the two adjacent fans are spliced. It can be understood that the splicing surface 4 with magnetic attraction can be the opposite side wall or adjacent side wall of the outer peripheral side wall of the frame 1, so that the frame 1 can be stacked on each other in the same direction or different directions to form a building block combination. The user can splice according to actual needs to make the fan combination more convenient (they can be directly placed and spliced ​​and fixed to each other). For example, when the fan group contains more than three fans with multi-sided magnetic attraction, the fans with multi-sided magnetic attraction can be stacked along one side direction or corner position to form a rectangular array, a straight line (or a straight line, see Figure 2 ), Z-shaped, cross-shaped (see Figure 5 ) or L-shaped arrangement. In a specific embodiment, the splicing surface 4 can also be the air inlet surface or air outlet surface of the frame 1 along the first direction, so that two fans can be stacked together. In addition, the fan can be magnetically mounted on an iron or magnetic mounting frame via the air inlet surface or air outlet surface.

[0051] For example, in this embodiment, four structural members 3 are provided, and the four structural members 3 are arranged in pairs on opposite sides of the frame 1, so that the side walls on both sides constitute the splicing surface 4 for the two fans to magnetically mate. It should be noted that the two structural members 3 on the same side are located on opposite sides of the splicing surface 4. In this way, the structural members 3 are installed near the corner of the frame 1, so that the structural members 3 can provide an effective magnetic field for the two adjacent side walls of the frame 1, thereby realizing two-dimensional splicing of multiple fans in the first direction and / or the second direction.

[0052] In some embodiments, the structural member 3 includes a magnet and a magnetic inductive member. There is a magnetic attraction between the magnet and the magnetic inductive member. The magnet is usually composed of a permanent magnet, such as a neodymium iron boron magnet, an aluminum nickel cobalt magnet, and a ferrite magnet, etc. The magnet can generate a stable magnetic field and has a strong magnetic force. The magnetic inductive member is a material or component that can respond to an external magnetic field, usually a ferromagnetic material, such as a metal member. The metal member can include but is not limited to any one of iron, nickel, cobalt, and iron-based alloys. For example Figure 1The four structural members 3 are installed on different sides of the frame 1 respectively, providing the fan with multiple splicing surfaces 4 with magnetic attraction. In some embodiments, the two structural members 3 on the same splicing surface 4 can be both magnet members or can be a magnet member and a magnetic induction member respectively. Correspondingly, the two structural members 3 on the opposite side can also be both magnet members or can be a magnet member and a magnetic induction member respectively. In one embodiment, when the two structural members 3 on the opposite sides are respectively a magnet member and a magnetic induction member, the two magnet members on the opposite sides are staggered. In other words, the magnet member on one side corresponds to the magnetically attracted structural member 3 on the other side as a magnetic induction member. In this way, when the two frames 1 are spliced ​​together, the magnetic induction member can complete the magnetic splicing of the two fans when the magnetic induction member reaches the distance of the magnetic attraction with the magnet member.

[0053] As can be seen from the above, the fan in this application provides magnetic attraction on multiple sides through multiple magnetic structural members 3. Adjacent fans attract each other through these splicing surfaces 4. When two fans are close to each other, the structural members 3 providing magnetic attraction on the frame 1 will generate attraction to fix the adjacent fans together. Through magnetic attraction, the fans can be easily adsorbed together without the need for additional fixing mechanisms (such as screws, locking devices, sliding structures, etc.). This avoids tedious alignment and sliding operations, greatly simplifying the difficulty of fan assembly and disassembly. At the same time, the multiple splicing surfaces 4 formed by the multiple structural members 3 allow the fan to be spliced ​​in multiple dimensions. Whether it is parallel splicing (second direction, third direction) or vertical splicing (first direction), a simple and fast connection can be achieved, greatly improving the flexibility of splicing. The magnetic attraction method provides a strong attraction to ensure that the spliced ​​fans are stably and firmly connected together. This avoids problems such as fan loosening and falling off due to loose splicing, and improves the overall stability and reliability of the fan system. By connecting multiple fans in parallel, the heat dissipation efficiency can be improved, especially in scenarios with high heat dissipation requirements, such as servers, graphics cards, central processing units and other electronic equipment in data centers and large computer rooms.

[0054] Figure 3 A schematic diagram of the internal structure of a shell provided in an embodiment of the present application is shown. Figure 4 FIG2 shows a schematic diagram of the internal structure of another housing provided by an embodiment of the present application. Figure 3 and Figure 4 At the same time, review Figure 1 and Figure 2, one end of the frame 1 along the first direction is an open structure, and inside the opening of the frame 1 are four corner grooves 11 opened inside the frame 1 to facilitate the installation of various parts of the fan. Exemplarily, a limiting groove 12 for installing the structural member 3 is opened inside the opening structure of the frame 1. The limiting groove 12 is adapted to the shape of the structural member 3. In one embodiment, the limiting groove 12 is attached to the inner side of the assembly surface of one side of the frame 1. In another embodiment, please refer to Figure 4 The limiting groove 12 is located at the connection between two adjacent side walls of the frame 1, that is, the limiting groove 12 is located at the diagonal corner of the frame 1. In this way, the structural member 3 can be installed in the limiting groove 12 at the diagonal corner. When the structural member 3 is a magnet, it can provide magnetic attraction to the two adjacent side walls and the air inlet and outlet surfaces of the frame 1. Figure 5 The front view of a plurality of fans with multi-faceted magnetic attraction in two dimensions is shown. Figure 5 As shown, when five fans with multi-sided magnetic attraction are spliced ​​in two dimensions, the structural member 3 located at the diagonal position can provide a strong magnetic attraction for the four sides of the frame 1, so that the five fans can be spliced ​​in the first direction and the second direction to form a cross-shaped assembly structure.

[0055] Figure 6 A perspective view of an exploded structure of a fan with multi-faceted magnetic attraction is shown. Figure 6 At the same time, review Figure 1 and Figure 2 In one embodiment, the magnet member serving as the structural member 3 is arranged in an elongated strip shape, and the length direction of the magnet member is the first direction of the shell, and the first direction is the thickness direction of the shell; the magnet member has an N pole and an S pole distributed along its own length direction, and the magnet member is mounted on a splicing surface 4 on one side of the shell. The polarities of the two magnet members that are magnetically attracted to each other are opposite, and the polarities of the two magnet members on the same splicing surface 4 are opposite at the same end, so that the two frames 1 can be quickly spliced ​​together when they are correctly assembled. In this way, when the two frames 1 are not correctly docked, for example, when two fans with opposite wind directions are docked, the two structural members 3 have the same polarity and repel each other, making it difficult for the user to incorrectly connect the two splicing surfaces 4 when splicing, further reducing the possibility of assembly errors.

[0056] In one embodiment, a rubber cover 5 is installed on the frame 1 to seal its opening, and a shock-absorbing rubber pad 6 is provided on the side of the rubber cover 5 facing away from the frame 1. The rubber cover 5 is designed to perfectly match the size of the opening of the frame 1. Therefore, in this embodiment, in order to completely seal the openings of the four corner grooves 11 of the frame 1, four rubber covers 5 are provided on the upper side. This ensures that the rubber cover 5 can firmly cover and seal the openings of the four corner grooves 11, playing the dual role of sealing and protecting. It is worth mentioning that the rubber cover 5 can be connected to the frame 1 by any of the following methods: bonding, screwing, or snapping. For example, multiple support plates 13 can be installed inside the opening of the frame 1, glue is applied to the side walls of the support plates 13, and then the rubber cover 5 is glued to the opening of the frame 1. Alternatively, a slot 131 can be provided on the support plate 13, and a buckle 51 can be installed at the corresponding position on the rubber cover 5. The rubber cover 5 is installed on the frame 1 by snapping the buckle 51 with the slot 131. Alternatively, the rubber cover 5 can be fixed to the frame 1 by screws, and the present application does not limit the connection method between the rubber cover 5 and the frame 1. Similarly, the connection method between the shock-absorbing rubber pad 6 and the rubber cover 5 can be any one of bonding, screwing and clamping. The specific connection implementation method is the same as the connection method between the rubber cover 5 and the frame 1, which will not be repeated here. Accordingly, the rubber cover 5 is provided with a clearance groove 52 for accommodating the embedding of the shock-absorbing rubber pad 6. The clearance groove 52 is adapted to the current status of the shock-absorbing rubber pad 6, which facilitates the installation of the shock-absorbing rubber pad 6 and enables the shock-absorbing rubber pad 6 to form a complete whole with the rubber cover 5 after installation, thereby increasing the aesthetics of the fan. In another embodiment, four shock-absorbing rubber pads 6 are also provided at the bottom (air inlet surface) of the frame 1 away from its own opening. In this way, the shock-absorbing rubber pads 6 distributed on the top and bottom surfaces of the four corners of the fan can reduce the vibration of the fan when it is in operation. For example, the shock-absorbing rubber pad 6 is typically made of a soft and elastic material (such as rubber, silicone, etc.) that can absorb external impact and vibration, mitigating the effects of these forces on the frame 1 and internal components. Thus, the provision of the shock-absorbing rubber pad 6 can effectively reduce the transmission of vibration to the frame 1 during operation, protecting the stable operation of internal sensitive components and preventing malfunctions or damage caused by vibration.

[0057] In one embodiment, when the structural member 3 is used as a magnet, in order to enhance the magnetic attraction of the structural member 3 on the air inlet and air outlet surfaces of the fan, a clearance hole 7 for the structural member 3 to pass through is provided at the corresponding positions of the rubber cover 5 and the shock-absorbing rubber pad 6, and the clearance hole 7 is adapted to the cross-section of the structural member 3. In one embodiment, the end of the structural member 3 can pass through the clearance hole 7 on the rubber cover 5 and the shock-absorbing rubber pad 6 to increase the magnetism of the structural member 3 on the air inlet and air outlet surfaces. In another embodiment, the end of the structural member 3 can also be hidden in the clearance hole 7 of the rubber cover 5 and the shock-absorbing rubber pad 6. As long as it can satisfy the requirement that one fan attracts another fan of the same specification within the splicing distance without falling off, this application does not make strict restrictions here. It can be understood that the shape of the magnet on the top and bottom surfaces can be circular or rectangular. For example, when the magnet is in contact with the splicing surface 4 on the side of the frame 1 (visible Figure 2 ), the end of the magnet can be set in a rectangular shape, so that the magnet can be closer to the side joint surface 4 of the frame 1, providing a higher magnetic attraction for the side joint surface 4 of the fan. For another example, when the magnet is at the diagonal position of the frame 1 (see Figure 4 ), in this case, the end of the magnet can be set in a circular shape, such as Figure 4 As shown by the arrow in the lower right corner of the middle fan, the magnet can provide uniform magnetic attraction to two adjacent side joint surfaces 4, and at the same time provide strong magnetic attraction to the air inlet surface and the air outlet surface.

[0058] like Figure 1 and Figure 2As shown, at least one positioning protrusion 14 is fixed on any one of the joint surfaces 4 of the frame body 1, and a positioning groove 15 matched with the positioning protrusion 14 is arranged on the other joint surface 4 of the frame body 1. The positioning protrusion 14 can be embedded in the positioning groove 15, and after the positioning protrusion 14 of any one fan is embedded in the positioning groove 15 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. In the embodiment, the positioning protrusion 14 and the positioning groove 15 are respectively arranged on the joint surfaces 4 of the opposite sides of the frame body 1. In this way, the cooperation of the positioning protrusion 14 and the positioning groove 15 can limit the movement between the frame bodies 1, avoid the sliding of one of the frame bodies 1 when the magnet member is subjected to external force, and make the mutual attraction of the two frame bodies 1 more stable. At the same time, the cooperation of the positioning protrusion 14 and the positioning groove 15 can realize accurate butt joint when the two fans are spliced, and can also cooperate with the magnet member to form a foolproof design, for example, when the first joint surface 4 of the two fans is spliced, the two fans cannot be spliced due to magnetic repulsion and the positioning protrusion 14 and the positioning groove 15 cannot be aligned, which protects the fan. The positioning protrusion 14 and the positioning groove 15 can be exchanged according to actual conditions. The number of the positioning protrusion 14 and the positioning groove 15 can be set according to design needs, for example, in the embodiment, two positioning protrusions 14 and two positioning grooves 15 are arranged. It should be noted that the two positioning protrusions 14 arranged on the same side are staggered, so that when the fan is spliced incorrectly, the positioning protrusions 14 and the positioning grooves 15 on the two sides of the frame body 1 cannot be aligned and embedded, so that the positioning protrusions 14 and the positioning grooves 15 play a foolproof role.

[0059] In one embodiment, a first connector 16 is provided on any one of the splicing surfaces 4 of the frame 1, and a second connector 17 is provided on the other splicing surface 4 of the frame 1 to electrically connect with the first connector 16. When the two fans are spliced ​​together, the splicing surfaces 4 of the two shells are magnetically attached, electrically connecting the first connector 16 and the second connector 17 to each other. In this embodiment, the first connector 16 and the second connector 17 are respectively located on the splicing surfaces 4 on opposite sides of the frame 1. Exemplarily, the electrical connection between the first connector 16 and the second connector 17 is typically achieved through metal contacts or conductive materials. For example, the first connector 16 is a slot with passive contacts, and the second connector 17 is a plug with spring contacts. It should be noted that both the first connector 16 and the second connector 17 are installed inside the fan through the opening of the frame 1. The first connector 16 / the second connector 17 can be integrated with the fan frame or fixed by snap-fitting, bonding, or screws. This is not strictly limited in this application, as long as the first connector 16 and the second connector 17 can be installed inside the fan. However, it should be noted that after the first connector 16 and the second connector 17 are installed within the frame 1, they can be electrically connected through the splicing surface 4 on the frame 1. Furthermore, the first connector 16 and the second connector 17 are electrically connected via a printed circuit board (PCB), with the first connector 16 and the second connector 17 being integrally formed with the PCB. The combination of the first connector 16 and the second connector 17 also limits the magnetic attraction between the two frames 1, making the magnetic attraction more stable.

[0060] The present application also provides an electronic device including the fan provided in the above embodiment. For example, the electronic device provided in this embodiment can be a computing device, which can also include a chassis. When two or more fans in the above embodiment are connected together, the connection can be completed by simply bringing the two fan side splicing surfaces 4 close together through magnetic attraction to achieve connection between the fans. The electrical connection is electrically conductive through the first connector 16 and the second connector 17, thereby achieving: one-time fixation and electrical internal connection between the fans.

[0061] After the fans are assembled and connected, they are placed on the component to be cooled, such as the aforementioned front panel of the chassis. The bottom surface of the fan is magnetically attracted to the metal surface of the chassis front panel, generating a magnetic attraction for secondary fixation. As needed, the fan can then be secured to the chassis front panel using screws for a third fixation. Accordingly, screw holes 8 are provided at the corners of the fan's sidewalls for screw fastening. In some embodiments, the fans can also be connected to the chassis via adhesive or snap-on connections, which are not intended to be exclusive. The first connector 16 of the outermost fan after assembly can be connected to the motherboard via a cable with pins to obtain power and signals. The assembled fans can then dissipate heat from the chassis. It should be noted that the electrical connection between the motor and other power-consuming units of the fan body 2 is a parallel connection, while the physical assembly of the fan body 2 and the other fan bodies 2 is in series. Thus, when operating, the assembled fan group achieves more ideal air volume and pressure over a wider range, meeting the heat dissipation requirements of the heat-generating components within the chassis and ensuring the service life of the heat-generating components within the chassis.

[0062] The design of this fan with multi-sided magnetic attraction has an innovative splicing mechanism. Compared with other splicing fans, it has multi-sided magnetic attraction, can be flexibly spliced ​​in two dimensions, and is easy to assemble and disassemble. The air inlet and outlet surfaces can be adsorbed onto iron or magnetic fixing frames. The collective splicing is simple and convenient, and no additional third collective structure is required to splice the fan bodies 2 together. When the two fan bodies 2 are close to each other, they will be adsorbed together. The four NS-coordinated splicing surfaces 4 with magnetic attraction also have anti-foolproof limits, and the connection is stable and will not be misplaced during installation. It effectively solves the problem of cumbersome assembly of traditional fans, and can accurately and reliably perform positioning, achieve rapid assembly, and optimize the splicing experience. In short, this technical solution not only meets the needs of users in terms of functionality, but also excels in aesthetics and economy, and has broad application prospects.
