Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0046] Example 1 With the rapid development of electronic technology, electronic components are developing towards high performance and high speed, which brings with it more and more heat generated by electronic components. In order to dissipate this heat, the industry usually installs fans in electronic devices to dissipate the heat of electronic components. The fan usually includes a fan frame, internal components housed in the fan frame, and conductive wires connecting the internal components with the external circuit. The existing arrangement of the conductive wires is: first install the bracket component on the fan frame, then install the wires on the bracket component, and finally clamp the wires through the fixing component so that the conductive wires and the terminal board are fixed in the same area to achieve quick plugging and unplugging of the fan. However, the above arrangement method requires the use of bracket components and multiple fixing components to fix the position of the conductive wires. The space occupied by the components is large, the heat dissipation space of the electronic device is reduced, the heat exchange efficiency is reduced, and the computing load of the heat dissipation system is increased; and the difficulty of fan assembly increases, and the production cost increases.

[0047] In view of this, please refer to Figure 1~Figure 5 The present application provides a fan 10, comprising a fan frame 1, a plurality of wires 2, a terminal board 3 and a limit assembly 4, wherein the first end of the wire 2 extends to the inside of the fan frame 1, and the second end of the wire 2 extends to the outside of the fan frame 1; the fan frame 1 comprises an installation area 11, and the installation area 11 is provided with a first limit member 13, a first mounting plate 14 and a second mounting plate 15, wherein the first mounting plate 14 and the second mounting plate 15 are arranged opposite to each other along a second direction Y, and the first mounting plate 14 and the second mounting plate 15 are respectively located on both sides of the first limit member 13 along a first direction X; the first limit member 13 is provided with a first limit hole 131 penetrating along the first direction X The first mounting plate 14 and the second mounting plate 15 are respectively provided with a mounting groove 141 which passes through along the second direction Y; the terminal board 3 is movably inserted in the mounting groove 141; the terminal board 3 is provided with a second limiting hole 31 and a plurality of wiring holes 32 which pass through along the thickness direction of the terminal board 3, and the axis of the first limiting hole 131 and the second limiting hole 31 coincide with the axis of the first direction X; the wiring hole 32 is configured to connect the second end of the wire 2; the limiting component 4 is configured to connect the first limiting hole 131 and the second limiting hole 31, and the inner diameter of the second limiting hole 31 is larger than the diameter of at least part of the limiting component 4, so that the terminal board 3 is floatingly connected with the mounting groove 141.

[0048] A wire arrangement hole 32 is provided on the terminal board 3 of the fan 10, and the wire 2 can be connected to the terminal board 3 through the wire arrangement hole 32, and a mounting groove 141 is provided in the mounting area 11 of the fan frame 1, and the terminal board 3 can be movably inserted into the mounting groove 141, so that the wire 2 and the terminal board 3 are located in the same area on the fan frame 1, and then the first limiting hole 131 and the second limiting hole 31 are connected by the limiting component 4, so that the terminal board 3 can be restricted in the mounting groove 141. At the same time, the inner diameter of the second limiting hole 31 is larger than the diameter of at least part of the limiting component 4, so that the terminal board 3 can be floatingly installed in the mounting groove 141, reducing the influence of vibration on the connection stability between the connector 100 and the terminal board 3; and the setting of the wire arrangement hole 32 makes it unnecessary to use additional components to fix and install the wire 2, and the assembly difficulty of the fan 10 is low, and the heat dissipation space inside the electronic device 200 can be guaranteed, the heat exchange efficiency is improved, and the computing load of the heat dissipation system is reduced.

[0049] Some implementation modes of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following implementation modes and embodiments may be combined with each other.

[0050] In the following, for the convenience of description, the first direction X is defined as the X-axis direction, the second direction Y is defined as the Y-axis direction, the third direction Z is defined as the Z-axis direction, and the first direction X, the second direction Y and the third direction Z are orthogonal to each other.

[0051] In some embodiments, the fan frame 1 is the outer shell of the fan 10, and can provide a stable mounting structure for other components of the fan 10 to ensure that the components can operate safely; at the same time, it can protect the internal components of the fan 10 from external factors, such as dust, humidity or other physical damage. The fan frame 1 used in this application is made of plastic or metal, which can be selected according to actual needs and is not limited here.

[0052] The installation area 11 is any area on the fan frame 1. For example, it can be the end face area of ​​the fan frame 1, or the side area of ​​the fan frame 1. It can be selected according to the arrangement of the fan 10 inside the electronic device to facilitate docking with the connector 100. No limitation is made here.

[0053] Please continue to refer to Figure 3, the installation area 11 is provided with a first stopper 13, a first mounting plate 14 and a second mounting plate 15, wherein the first mounting plate 14 and the second mounting plate 15 are arranged opposite to each other along the second direction Y; the first stopper 13 is provided with a first stopper hole 131 penetrating along the first direction X, the first mounting plate 14 and the second mounting plate 15 are provided with a mounting groove 141 penetrating along the second direction Y, and the first mounting plate 14 and the second mounting plate 15 are located on both sides of the first stopper 13 when viewed along the first direction X. It can be understood that the axis of the first stopper hole 131 extends along the first direction X, and the mounting grooves 141 provided on the first mounting plate 14 and the second mounting plate 15 are located on the same straight line along the second direction Y, that is, the axis of the first stopper hole 131 along the first direction X is perpendicular to the penetrating direction of the mounting groove 141.

[0054] It should be noted that the present application does not limit the depth and width of the installation groove 141 , and the depth and width can be selected according to the size of the terminal board 3 .

[0055] In the present application, the first limit member 13, the first mounting plate 14 and the second mounting plate 15 can be an integrally formed structure or a combined structure with the fan frame 1. The combined structure includes bonding, welding or detachable connection, etc. It can be understood that when the components of the installation area 11 and the fan frame 1 are an integrally formed structure, a bonding structure or a welding structure, the overall strength of the fan frame 1 is high and the service life is longer; when the components of the installation area 11 and the fan frame 1 are a detachable structure, such as a mating connection between a boss and a groove, when the components of the installation area 11 are damaged, they can be replaced separately, thereby reducing the maintenance cost of the fan 10.

[0056] Optionally, the first stopper 13, the first mounting plate 14 and the second mounting plate 15 are integrally formed with the fan frame 1. It can be understood that the components of the mounting area 11 are integrally formed with the fan frame 1, and no additional fixing components are required to fix the first stopper 13, the first mounting plate 14 and the second mounting plate 15 on the fan frame 1. The first stopper 13, the first mounting plate 14 and the second mounting plate 15 occupy a smaller system space, and the fixing and installation of the wire 2 and the terminal board 3 do not require the use of additional fixing components, thereby ensuring the heat dissipation space inside the electronic device, improving the heat exchange efficiency, and reducing the computing load of the heat dissipation system. At the same time, the fan frame 1 has a higher strength and a longer service life.

[0057] In some embodiments, the terminal board 3 is used to connect the fan 10 to a power source or a control system, and provides an electrical interface for the connector 100 so that the fan 10 can receive power and work. Figure 4The terminal board 3 is provided with an electrical contact area 33, which is distributed on two surfaces of the terminal board 3, and at least part of the electrical contact area 33 has different areas. It can be understood that the electrical contact area 33 is used for electrical connection with the connector 100. The electrical contact area 33 is distributed on both sides of the terminal board 3 and has different areas, which can provide more contact surfaces and help ensure a more stable electrical connection. In a vibration environment, the large contact point can reduce the risk of circuit breaking due to poor contact and improve the reliability and durability of the fan 10.

[0058] The terminal board 3 is inserted into the mounting groove 141 of the first mounting plate 14 and the second mounting plate 15, and the thickness of the contact portion between the terminal board 3 and the mounting groove 141 is less than the width of the mounting groove 141, that is, along the first direction X, the terminal board 3 can be displaced in the mounting groove 141. It can be understood that in the actual installation process, due to manufacturing tolerances, assembly errors and other reasons, there are certain alignment problems when the connector 100 and the terminal board 3 are docked. The terminal board 3 is movable along the first direction X in the mounting groove 141, so that the terminal board 3 and the connector 100 can be smoothly docked, which simplifies the installation process and reduces the stress concentration caused by forced alignment. The present application does not limit the thickness difference between the mounting groove 141 and the terminal board 3, and can be selected according to the specific application scenario and specifications of the fan 10.

[0059] The terminal board 3 movably inserted in the mounting groove 141 is provided with a second limiting hole 31 which passes through in the thickness direction. When the terminal board 3 is installed in the mounting groove 141, the second limiting hole 31 coincides with the first limiting hole 131 of the first limiting member 13 along the axis of the first direction X. By connecting the first limiting hole 131 and the second limiting hole 31 through the limiting component 4, the terminal board 3 can be floatingly connected with the mounting groove 141.

[0060] In the embodiment of the present application, floating connection means that when the terminal board 3 is installed in the installation groove 141, the size of the installation groove 141 is larger than the size of the installation part of the terminal board 3, and there is a certain gap between the terminal board 3 and the installation groove 141, so that the terminal board 3 can move slightly in one or more directions. It can be understood that floating installation can eliminate certain installation errors, ensure the correct docking of the terminal board 3 and the connector 100, and floating installation plays a role of shock absorption and buffering to a certain extent, reducing the influence of the mechanical vibration of the fan frame during the rotation of the fan 10 on the connection stability of the terminal board 3 and the connector 100.

[0061] Please continue to refer to Figure 5The limiting assembly 4 includes an expansion member 41 and a first positioning pin 42. The expansion member 41 is inserted into the first limiting hole 131. The first limiting hole 131 includes a first hole section 1311 and a second hole section 1322. The second hole section 1322 is arranged at an end of the first hole section 1311 away from the installation area 11, and the diameter of the second hole section 1322 is greater than the diameter of the first hole section 1311. The expansion member 41 includes an expansion body 412 and a second limiting portion 413. The diameter of the second limiting portion 413 is greater than the inner diameter of the first hole section 1311. The expansion body 412 is inserted into the first hole section 1311, and the second limiting portion 413 is accommodated in the second hole section 1322. The second limiting portion 413 is installed without protruding from the surface of the first limiting member 13. It can be understood that the second limiting portion 413 does not protrude from the surface of the first limiting member 13 , which improves the aesthetics and reduces the collision of other components in the fan with the limiting assembly 4 , thereby ensuring stable installation of the limiting assembly 4 .

[0062] The expansion member 41 is provided with an expansion hole 411. When the expansion member 41 is embedded in the first limiting hole 131, the axis of the second limiting hole 31 coincides with the axis of the expansion hole 411 along the first direction X. The first positioning pin 42 includes a first limiting portion 421 and a pin body 422 connected to each other. The diameter of the pin body 422 is smaller than the diameter of the second limiting hole 31. The pin body 422 is inserted through the expansion hole 411 and the second limiting hole 31. The first limiting portion 421 abuts against the surface of the first limiting member 13 away from the installation area 11. The pin body 422 causes at least part of the expansion member 41 to expand and deform in a direction perpendicular to the axis of the expansion hole 411. It can be understood that after the first positioning pin 42 is inserted through the expansion member 41 to deform it, the diameter of part of the expansion member 41 is larger than the diameter of the first limiting hole 131, which can ensure that the first positioning pin 42 will not be separated from the first limiting hole 131, thereby ensuring the stable installation of the terminal board 3 in the installation groove 141 during operation.

[0063] By cooperating with the expansion piece 41, the first positioning pin 42 and the mounting groove 141, the terminal board 3 can be confined in the mounting groove 141, thereby realizing the floating installation of the terminal board 3 in the mounting groove 141, and reducing the influence of vibration during the rotation of the fan 10 on the connection stability between the connector 100 and the terminal board 3.

[0064] In some embodiments, please continue to refer to Figure 4, the wiring holes 32 on the terminal board 3 are arranged linearly and symmetrically distributed on both sides of the second limiting hole 31 along the length direction, so that the wire 2 can pass through the wiring hole 32 and be welded to the terminal board 3, so that the conductive wire and the terminal board 3 are fixed in the same area. It can be understood that after the wire 2 is connected to the wiring hole 32, it is distributed on both sides of the second limiting hole 31, that is, the terminal board 3 and the limiting component 4 are connected in the center. When the connector 100 is plugged into the terminal board 3, the terminal board 3 is subjected to more uniform force, which speeds up the docking speed of the two; and the arrangement of the wire 2 will not affect the limiting process of the limiting component 4 on the terminal board 3, and the wiring of the wire 2 is more reasonable, further increasing the heat dissipation space inside the electronic device.

[0065] During actual application, the terminal board 3 is inserted into the installation groove 141 along the third direction Z, and the expansion piece 41 is embedded in the first limiting hole 131, and the first positioning pin 42 is passed through the second limiting hole 31 and the expansion hole 411, so that the expansion piece 41 is deformed in the direction away from the axis of the expansion hole 411, ensuring that the first positioning pin 42 will not be separated from the first limiting hole 131, thereby realizing the floating connection of the terminal board 3 in the installation groove 141.

[0066] Example 2 The difference from the first embodiment is that the structure and assembly method of the position limiting component 4 are different. Specifically: Please refer to Figure 6~Figure 10 The limiting assembly 4 includes a positioning body 43 and a second positioning pin 44. At least part of the positioning body 43 is embedded in the first limiting hole 131, and the positioning body 43 does not protrude from the surface of the first limiting member 13 after installation. It can be understood that the above installation method can improve the aesthetics of the installation area 11 while reducing the collision of other components with the positioning body 43, thereby ensuring the stable installation of the positioning body 43.

[0067] A first positioning column 431 is provided on the surface of the positioning body 43 facing the installation area 11. The first positioning column 431 is a columnar structure. The diameter of the columnar structure is smaller than the diameter of the first limiting hole 131 and the second limiting hole 31. The first positioning column 431 can connect the first limiting hole 131 and the second limiting hole 31 to ensure that the terminal board 3 will not detach from the installation groove 141 along the installation direction.

[0068] The positioning body 43 is provided with a first positioning hole 432 that passes through along the third direction Z, and the first limiting member 13 is provided with a second positioning hole 132 at the top along the third direction Z. The first positioning hole 432 coincides with the axis of the second positioning hole 132 along the third direction Z. The cross-sectional shapes of the first positioning hole 432, the second positioning hole 132 and the first positioning column 431 can be circular or other polygonal, which can be selected according to actual needs and are not limited here. The second positioning pin 44 can be installed to the first positioning hole 432 and the second positioning hole 132 along the third direction Z, so that the limiting component 4 is fixed to the first limiting hole 131. It can be understood that by fixing the positioning body 43 in the first limiting hole 131 through the second positioning pin 44, the limiting component 4 occupies a smaller system space, which can further increase the heat dissipation space inside the electronic device.

[0069] In actual application, the terminal board 3 is inserted into the installation groove 141 along the third direction Z, and the positioning body 43 is embedded in the first limiting hole 131, and the first positioning column 431 is penetrated through the first limiting hole 131 and the second limiting hole 31. At the same time, the second positioning pin 44 can be installed to the first positioning hole 432 and the second positioning hole 132 along the third direction Z, so that the positioning body 43 is fixed to the first limiting hole 131, completing the fixing process of the limiting assembly 4. At this time, the terminal board 3 is floatingly installed in the installation groove 141.

[0070] Example 3 The difference from the first embodiment is that the structure and assembly method of the position limiting component 4 are different. Specifically: Please refer to Figure 11~Figure 15 The limiting assembly 4 includes a limiting plate 45, which is located on the side of the first limiting member 13 away from the installation area 11, and a second positioning column 451 is provided on its surface facing the installation area 11. The second positioning column 451 is penetrated by the first limiting hole 131 and the second limiting hole 31, and the diameter of the second positioning column 451 is smaller than the inner diameter of the first limiting hole 131 and the second limiting hole 31. Through the setting of the second positioning column 451, the limiting plate 45 can be initially clamped in the installation area 11, and the terminal board 3 can be floatingly connected with the installation groove 141.

[0071] The limiting assembly 4 further includes a clamping arm 452, which extends from the wall surface of the limiting plate 45 toward the direction close to the first mounting plate 14 and the second mounting plate 15. The clamping arm 452 specifically includes a first extension arm 4522 and a second extension arm 4523 which are connected and vertically arranged. The second extension arm 4523 is bent from one end of the first extension arm 4522 away from the limiting plate 45 toward the direction close to the first mounting plate 14 and the second mounting plate 15. The end of the second extension arm 4523 away from the limiting plate 45 is provided with a buckle portion 4521. It should be noted that the length of the first extension arm 4522 is greater than the spacing distance between the first mounting plate 14 and the second mounting plate 15, and the length of the second extension arm 4523 is greater than the width of the first mounting plate 14 and the second mounting plate 15 along the first direction X, so that after the limiting plate 45 is installed, the buckle portion 4521 can be clamped with the side of the first mounting plate 14 and the second mounting plate 15 away from the limiting plate 45.

[0072] It should be noted that the present application does not limit the specific structure of the snap portion 4521, which may be a triangular snap or a rectangular snap, etc., which can stably connect the snap arm 452 to the first mounting plate 14 and the second mounting plate 15, and can be selected according to actual needs.

[0073] Furthermore, the first mounting plate 14 and the second mounting plate 15 are provided with a clamping groove 142 on the side wall close to the first stopper 13, and the clamping groove 142 can be used to receive at least part of the first extension arm 4522. It can be understood that at least part of the first extension arm 4522 is received in the clamping groove 142, which can reduce the distance between the stopper plate 45 and the terminal board 3 after the stopper assembly 4 is installed, thereby reducing the system space occupied by the stopper assembly 4 along the first direction X.

[0074] After the second positioning column 451 connects the first limiting hole 131 and the second limiting hole 31, it can limit the terminal board 3 from being separated from the limiting groove, and the clamping portion 4521 of the clamping arm 452 and the first mounting plate 14 and the second mounting plate 15 can prevent the limiting protrusion from being separated from the first limiting hole 131, thereby ensuring the stable installation of the terminal groove.

[0075] During actual application, the terminal board 3 is inserted into the installation groove 141 along the third direction Z, the second positioning column 451 of the limit plate 45 connects the first limit hole 131 and the second limit hole 31, and the buckle portion 4521 can be clamped with the first mounting plate 14 and the second mounting plate 15 on the side away from the limit plate 45, and the first extension arm 4522 is accommodated in the clamping groove 142, so that the limit plate 45 is stably installed in the installation area 11, thereby limiting the terminal board 3. At this time, the terminal board 3 is floatingly installed in the installation groove 141.

[0076] It should be noted that the diameter of the contact portion between the limit assembly 4 of the present application and the second limit hole 31 of the terminal board 3 is smaller than the inner diameter of the second limit hole 31, so that the floating of the terminal board 3 in the first direction X, the second direction Y and the third direction Z are not affected. The present application does not limit the diameter difference, and it can be selected according to the specific application scenarios and specifications of the fan 10.

[0077] It should also be noted that the shape of the terminal board 3 matches the shape of the connector 100 , and the type of the connector 100 can be selected according to actual needs, which is not limited here.

[0078] Example 4 Please refer to Fig.16 , Fig.17 and Fig.18 Different from Embodiment 1, Embodiment 2 and Embodiment 3, the installation area 11 is further provided with a second limiting member 12, and the first limiting member 13, the second limiting member 12, the first mounting plate 14, the second mounting plate 15 and the installation area 11 are an integrally formed structure.

[0079] Specifically, the second limiting member 12 and the first limiting member 13 are arranged opposite to each other along the first direction X, and the second limiting member 12 is provided with a third limiting hole 121 penetrating along the first direction X. When viewed along the first direction X, the first mounting plate 14 and the second mounting plate 15 are located on both sides of the second limiting member 12 and the first limiting member 13. It can be understood that the axes of the third limiting hole 121 and the first limiting hole 131 along the first direction X coincide with each other, and the mounting grooves 141 provided on the first mounting plate 14 and the second mounting plate 15 are located on the same straight line along the second direction Y, that is, the axes of the third limiting hole 121 and the first limiting hole 131 along the first direction X are perpendicular to the penetrating direction of the mounting groove 141.

[0080] The terminal board 3 movably inserted in the mounting groove 141 is located between the second limiting member 12 and the second limiting portion 413 along the first direction X, and the terminal board 3 is provided with a second limiting hole 31 which passes through along the thickness direction. When the terminal board 3 is installed to the mounting groove 141, the second limiting hole 31 coincides with the third limiting hole 121 of the second limiting member 12 and the first limiting hole 131 of the first limiting member 13 along the axis line of the first direction X. By connecting the third limiting hole 121, the first limiting hole 131 and the second limiting hole 31 through the limiting assembly 4, the terminal board 3 can be floatingly connected to the mounting groove 141.

[0081] Example 5 Different from the first embodiment, the second embodiment, the third embodiment and the fourth embodiment, the fan further includes a shock absorbing member 5 .

[0082] Please refer to Fig.19Taking the structure of the fan 10 of Example 2 as an example, the shock absorber 5 is arranged in the mounting groove 141 and is located between the surface of the terminal board 3 and the wall surface (side wall surface and bottom wall surface) of the mounting groove 141. It can be understood that a certain vibration will be generated during the operation of the fan, and this vibration is transmitted to the terminal board 3 through the abutment between the mounting groove 141 and the terminal board 3, which has a certain impact on the connection stability between the terminal board 3 and the connector 100. By arranging the shock absorber 5 between the surface of the terminal board 3 and the wall surface of the mounting groove 141, the impact of the fan vibration on the connection stability between the terminal board 3 and the connector 100 can be further reduced.

[0083] It can be understood that, in addition to the structure shown in Example 2, the arrangement of the shock absorbing member 5 in the installation groove 141 can also be applied to Example 1, Example 3 and Example 4.

[0084] As an optional technical solution of the present application, different from Examples 1 to 5, the limit assembly 4 may not be provided, and a structural component for opening or closing the entrance of the installation slot 141 may be provided at the entrance of the installation slot 141 of the first installation plate 14 and the second installation plate 15, wherein the structural component includes but is not limited to a baffle, a matching structure of a pin and a hole installed along the first direction, or an elastic clip, etc., which can open or close the installation slot 141. It can be understood that after the terminal board 3 is installed to the installation slot 141 along the third direction, the entrance of the installation slot 141 is closed by the structural component, which can limit the terminal board 3 from detaching from the entrance, thereby realizing a floating connection between the terminal board 3 and the installation slot 141.

[0085] As an optional technical solution of the present application, different from the embodiments 1 to 5, the position limiting assembly 4 and the mounting groove 141 may not be provided, and a mounting hole penetrating along the second direction may be provided on the first mounting plate 14 and the second mounting plate 15, mounting rods are provided at both ends of the terminal board 3, the inner diameter of the mounting hole is larger than the diameter of the mounting rod, and the side walls of the first mounting plate 14 and the second mounting plate 15 are provided with a mounting channel connected to the mounting hole, and the mounting channel includes at least one bending portion. It can be understood that the terminal board 3 can enter the mounting hole along the mounting channel through the mounting rod, so that the mounting rod can move in the mounting hole along the first direction and the second direction, and due to the bending path setting of the mounting channel, the terminal board 3 will not be separated from the mounting hole.

[0086] As an optional technical solution of the present application, different from Examples 1 to 5, the limit assembly 4 and the mounting groove 141 may not be provided, and a first mounting hole extending along the second direction is provided on the first mounting plate 14 and the second mounting plate 15, and second mounting holes are provided on both sides of the terminal board 3 along the second direction, respectively. The fan 10 also includes a mounting pin, and a portion of the mounting pin has a diameter smaller than the diameter of the mounting hole. It can be understood that the terminal board 3 can be installed in the mounting area 11, and the mounting pin passes through the first mounting hole and is connected to the second mounting hole of the terminal board. At this time, the mounting pin can move in the first mounting hole, thereby realizing the floating installation of the terminal board 3 in the mounting area.

[0087] It should be noted that the shapes of the first limiting hole 131, the second limiting hole 31, the third limiting hole 121, the first positioning hole 432, the second positioning hole 132 and the wiring hole 32 provided in the present application include but are not limited to round holes or other polygonal holes, which can be selected according to actual needs and are not limited here.

[0088] The present application also provides an electronic device 200, which includes but is not limited to a server, a switch or a router. Fig. 20 Taking the central processing unit 201 of the server as an example, the main components inside the central processing unit 201 include an operator 2011, a controller 2012 and a register 2013, among which the operator 2011 is used for arithmetic and logical operations, and the controller 2012 directs and coordinates the work of other components to ensure the orderly operation of various parts of the computer; the register 2013 is used to temporarily store instructions, data and addresses, allowing the central processing unit 201 to quickly obtain information and improve processing efficiency; the operation process of the operator 2011, the controller 2012 and the register 2013 will generate heat. At this time, the fan 10 can promote air flow to take away the heat on the radiator, ensure that the central processing unit 201 works at a suitable temperature, and prevent the central processing unit 201 from being degraded or damaged due to overheating.

[0089] In addition to the above examples, the fan 10 can be applied to other electronic devices 200, and the number of fans 10 is not limited to eight. Eight is only an example. A larger number of fans 10 can be used, such as ten or twelve, etc., or a smaller number of fans 10 can be used, such as one, two or four, etc. The type of electronic device 200 and the number of fans 10 can be selected according to actual needs and are not limited here.
