Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] With the rise of big data, cloud computing and AI (Artificial intelligence), the application demand for electronic devices such as servers and supercomputers is becoming more and more widespread. In order to improve the competitiveness of electronic devices, it is necessary to increase the computing speed and storage capacity by increasing the configuration density. The increase in computing speed and storage capacity can easily lead to increasing power consumption of electronic devices. At present, the high configuration density in electronic devices can easily lead to difficulties in heat dissipation in the device, resulting in overheating in local areas of the device, making the heat dissipation of the device gradually become a bottleneck. Summary of the invention

[0003] The embodiments of the present application provide an electronic device, which can enable the electronic device to have good heat dissipation performance.

[0004] An embodiment of the present application provides an electronic device, the electronic device comprising:

[0005] A chassis, the chassis comprising a first bottom plate, and a receiving space is provided inside the chassis;

[0006] a fan mounting plate, the fan mounting plate being located in the receiving space and fixedly connected to the first bottom plate; and

[0007] A fan module, the fan module is located in the receiving space, the fan module includes a fan frame and a fan, the fan frame includes a second base plate, a first side plate and a second side plate, the second base plate is detachably connected to the fan mounting plate and is located on the side of the fan mounting plate away from the first base plate, the first side plate and the second side plate are respectively connected to the two sides of the second base plate, the first side plate and the second side plate are relatively arranged in the length direction of the electronic device, and the second base plate, the first side plate and the second side plate cooperate to fix the fan.

[0008] It is understandable that, compared with the prior art, at least five of the six sides of the fan need to be fixed, resulting in a larger module volume of the fan module. In the embodiment of the present application, by making the second bottom plate cooperate with the first side plate and the second side plate to fix the fan, three of the six sides of the fan can be fixed, and the fixed connection between the fan frame and the fan can be achieved by fixing three of the six sides of the fan, so that on the basis of meeting the connection strength between the fan frame and the fan, the space occupied by the fan frame due to the need to fix multiple sides of the fan can be released, the space occupied by the fan frame can be reduced, the volume of the fan module can be minimized, and the fan module can be further miniaturized.

[0009] In addition, since the first side plate and the second side plate are only arranged relative to each other in the length direction of the electronic device, the fan module can have a smaller width dimension in the width direction of the electronic device, so that this part of the space can be vacated and as many fan modules as possible can be arranged in the limited space layout inside the electronic device. On the basis of ensuring that the electronic device has good working performance, increasing the number of fan modules can reduce the adverse effects on the selection of fan modules, further improve the heat dissipation performance of the electronic device, and achieve good heat distribution performance of the electronic device.

[0010] In a possible implementation manner, the fan mounting plate includes a mounting plate body and a first limiting structure, the mounting plate body is fixedly connected to the first bottom plate, and the first limiting structure is provided on the mounting plate body;

[0011] The fan frame further includes a second limiting structure, which is disposed on the second bottom plate. The fan frame is fixed to the fan mounting plate through the cooperation between the second limiting structure and the first limiting structure.

[0012] It is understandable that by plugging the first limiting structure of the fan mounting plate with the second limiting structure of the fan module, a clamping connection between the first limiting structure and the second limiting structure can be achieved, thereby achieving the limiting fixation of the fan mounting plate and the fan module in the vertical direction. By limiting the fan mounting plate and the fan module in the vertical direction, the fan mounting plate and the fan module can be fixedly connected without occupying the horizontal space, and this part of the space can be released to set up a larger number of fan modules, which is conducive to improving the overall heat dissipation performance of the electronic equipment.

[0013] In a possible implementation manner, the second bottom plate includes a first surface and a second surface disposed opposite to each other, the first surface abuts against the mounting plate body, the second surface abuts against the fan, the second limiting structure is protruded relative to the second surface, the second limiting structure has a plug hole, and the plug hole penetrates the second limiting structure and the second bottom plate along a height direction of the electronic device;

[0014] The first limiting structure is protruded relative to the surface of the mounting plate body toward the second bottom plate, and the first limiting structure can pass through the plug hole to be fixedly connected with the second limiting structure.

[0015] In a possible implementation, when the first limiting structure is inserted into the plug hole, one end of the first limiting structure away from the mounting plate body is protruded relative to the second limiting structure, and the first limiting structure cooperates with the second limiting structure to fix the second base plate to the fan mounting plate.

[0016] Of course, in other embodiments, when the first limiting structure is inserted into the plug hole, the end of the first limiting structure away from the mounting plate body may also be surrounded by the second limiting structure or be flush with the end of the second limiting structure away from the second bottom plate, and no strict setting is made for this.

[0017] In a possible implementation manner, a protrusion is provided on the inner wall of the plug hole, and the protrusion is arranged around the circumferential direction of the plug hole;

[0018] A groove is provided on the outer surface of the first limiting structure, and the groove is arranged around the circumferential direction of the first limiting structure;

[0019] When the first limiting structure is inserted into the inserting hole, at least a portion of the protrusion is located in the groove.

[0020] It is understandable that by providing a protrusion on the inner wall of the plug hole, the inner wall of the plug hole can be made to present an uneven undulating shape. By providing a groove on the outer surface of the first limiting structure, the outer surface of the first limiting structure can be made to present an uneven undulating shape. Therefore, when the second limiting structure is connected to the first limiting structure of the fan mounting plate, part of the protrusion can be accommodated in the groove of the first limiting structure, thereby achieving the locking of the second limiting structure and the first limiting structure of the fan mounting plate.

[0021] In a possible implementation manner, a cross-sectional width of the groove along a height direction of the first limiting structure gradually decreases from an outer surface of the first limiting structure toward a center line of the first limiting structure.

[0022] Under this setting, the cross-sectional shape of the groove along the third direction can be a trumpet shape that is larger on the outside and smaller on the inside. When the trumpet-shaped groove is connected to the second limiting structure of the fan module, the inner wall surface of the groove can serve as a guiding slope that can provide a guiding effect for the second limiting structure, thereby guiding the second limiting structure to be quickly aligned with the first limiting structure, so that the first limiting structure and the second limiting structure of the fan module can be quickly plugged in and out, and the reliability is better.

[0023] In a possible implementation manner, the plug hole includes a first hole, a second hole and a third hole, the third hole is connected between the first hole and the second hole, the third hole is closer to the second bottom plate relative to the second hole, and the protrusion is protruding from the hole wall of the second hole;

[0024] The cross-sectional width of the first hole along the height direction of the second limiting structure gradually decreases from the second bottom plate toward the fan;

[0025] A cross-sectional width of the second hole along a height direction of the second limiting structure gradually increases from the second bottom plate toward the fan.

[0026] It is understandable that, during the connection process between the second limiting structure and the first limiting structure, the first hole will be the first hole-type structure in the plug-in hole to contact the first limiting structure. By setting the hole wall of the first hole to be an inclined plane inclined relative to the first direction, the hole wall of the first hole can be used as a guiding inclined plane to form a trumpet-shaped expansion shape at the outer end of the first hole, wherein the outer end of the first hole refers to the end of the first hole close to the first surface. The shape setting of the first hole can provide a certain fault tolerance space for the first limiting structure. Even if the first limiting structure is not aligned with the center of the plug-in hole, it can slide into the plug-in hole under the guidance of the first hole, further improving the plug-in efficiency and plug-in success rate of the first limiting structure and the second limiting structure.

[0027] During the connection process between the second limiting structure and the first limiting structure, the second hole will be the last hole structure in the plug-in hole to contact the first limiting structure. By setting the hole wall of the second hole as an inclined plane inclined relative to the first direction, the hole wall of the second hole can be used as a guiding inclined plane to form a trumpet-shaped expansion shape at the outer end of the second hole, wherein the outer end of the second hole refers to the end of the second hole away from the second surface. The shape setting of the second hole can provide a guiding effect for the first limiting structure, so that the first limiting structure can be easily passed through the plug-in hole.

[0028] In a possible implementation manner, the fan includes a fan body, a first fixing plate, and a second fixing plate, wherein the first fixing plate and the second fixing plate are respectively connected to opposite sides of the fan body;

[0029] The fan body, the first fixing plate and the second fixing plate are all in contact with the second bottom plate, the orthographic projection of the fan body on the first fixing plate completely falls into the first fixing plate, the orthographic projection of the fan body on the second fixing plate completely falls into the second fixing plate, and along the circumferential direction of the fan, the circumference of the fan body is smaller than the circumference of the first fixing plate and the circumference of the second fixing plate;

[0030] The fan body, the first fixing plate and the second fixing plate are cooperated to form an installation space, and the second limiting structure is located in the installation space.

[0031] Under this setting, among the four side parts of the fan connected in sequence, at the connection between any two adjacent side parts, the fan body will be recessed inwardly relative to the first fixing plate and the second fixing plate, so that four inwardly recessed arc-shaped spaces will be formed around the fan. This arc-shaped space can provide a certain setting space for other structural parts in the fan to be accommodated therein.

[0032] It is understandable that the installation space formed by the fan body, the first fixing plate and the second fixing plate is an idle space in the fan module, and the second limiting structure is arranged in this installation space, so as not to interfere with other structures in the fan module, and to make full use of the idle space in the fan module, thereby effectively improving the space utilization rate of the fan module. For example, the installation space can be an arc-shaped space.

[0033] In a possible implementation manner, the number of the fans is two, and among the two fans, the first fixing plate of one fan is fixedly connected to the first side plate, the first fixing plate of the other fan is fixedly connected to the second side plate, and the second fixing plate of one fan abuts against the second fixing plate of the other fan;

[0034] There are two second limiting structures, one second limiting structure is located in the installation space of one fan, and the other second limiting structure is located in the installation space of another fan. The two second limiting structures are arranged along the diagonals of the second bottom plate.

[0035] It should be noted that the number of second limiting structures is not limited to two, it can be one or more than two, and their positions can also be arranged accordingly according to the actual application requirements of the electronic device. It is only necessary to satisfy the correspondence between one second limiting structure and one first limiting structure. The embodiments of the present application do not impose strict restrictions on the number and specific setting positions of the second limiting structures.

[0036] In a possible implementation manner, the first fixing plate is provided with a plurality of mounting holes, the plurality of mounting holes are spaced apart and distributed on the first fixing plate, and each of the mounting holes penetrates the first fixing plate along a thickness direction of the first fixing plate;

[0037] The fan frame further includes a plurality of third limiting structures, which are spaced apart and distributed on a surface of the first side plate facing the second side plate and a surface of the second side plate facing the first side plate, and each of the third limiting structures includes a column and a clamping portion, and one end of the column is connected to the clamping portion;

[0038] The other end of the column close to the first side plate is connected to the first side plate, and the other end of the column close to the second side plate is connected to the second side plate;

[0039] When the third limiting structure is inserted into the mounting hole, the column passes through the mounting hole, and the clamping portion abuts against the first fixing plate to fix the fan frame and the fan.

[0040] It is understandable that by making the fan frame include the third limiting structure and making the third limiting structure of the fan frame clamped and fixed with the mounting hole of the fan, the third limiting structure of the fan frame can be matched with the mounting hole of the fan to achieve the horizontal limiting fixation between the fan frame and the fan. In the horizontal direction, the fan mounting plate and the fan module are mutually limited, which can also prevent the fan from slipping off the fan frame, and the reliability is better.

[0041] In a possible embodiment, the fan frame also includes a connecting structure, which is arranged on a side of the first side panel away from the second side panel or a side of the second side panel away from the first side panel, and the connecting structure is provided with a card slot. The fan module also includes a connector, which is electrically connected to the fan, and part of the connector is located in the card slot. The connector is used to be electrically connected to a fan control board that controls the fan.

[0042] It can be understood that the connector is electrically connected to the fan, and the connector can be plugged into the fan control board, thereby electrically connecting the fan control board and the fan, and realizing a current path between the fan module and the fan control board.

[0043] In a possible implementation manner, the mounting plate body includes a first transition portion, a second transition portion, a first mounting portion, a second mounting portion, and a third mounting portion, wherein the first mounting portion, the second mounting portion, and the third mounting portion are sequentially arranged in a length direction of the electronic device and in a height direction of the electronic device, the first transition portion is connected between the first mounting portion and the second mounting portion, and the second transition portion is connected between the second mounting portion and the third mounting portion;

[0044] The first mounting portion is fixedly connected to the first bottom plate of the chassis, the third mounting portion is fixedly connected to the second bottom plate of the fan frame, and the first limiting structure is located at the third mounting portion;

[0045] The electronic device further comprises a fan control board, the fan control board is connected to the second mounting portion, and the fan control board is electrically connected to the fan by plugging into the connector.

[0046] Under this setting, the various parts of the mounting plate body can present a stepped distribution with height differences in the third direction, so that the fixing connection between the entire mounting plate body and the first bottom plate of the chassis can be achieved only by contacting a relatively small number of parts of the mounting plate body with the first bottom plate of the chassis. The rest of the mounting plate body can be suspended relative to the first bottom plate of the chassis, so that the board surface area in contact with the first bottom plate of the chassis can be reduced on the basis of ensuring the connection strength between the mounting plate body and the first bottom plate of the chassis, and the space for other structural parts arranged on the first bottom plate of the chassis can be maximized, which is conducive to improving the space utilization of the electronic equipment. Exemplarily, the gap area between the rest of the mounting plate body and the first bottom plate of the chassis can be the wiring space of the electronic equipment.

[0047] It is understandable that the fan control board can independently control one fan module or multiple fan modules among multiple fan modules, and the fan control board is also electrically connected between multiple fan modules and the single board, so multiple fan modules can be finely controlled through the single board. That is, by independently controlling one or more fan modules among multiple modules, the number of fans that meet the corresponding heat dissipation requirements can be configured according to the temperature in the chassis, thereby achieving precise speed regulation of the fan module and upgrading the heat dissipation capacity.

[0048] In a possible implementation manner, the chassis further includes a first cover plate, the first bottom plate and the first cover plate are arranged opposite to each other in a height direction of the electronic device, the electronic device further includes a padding member and a buffer member, the padding member is connected to a surface of the first cover plate facing the first bottom plate, and the buffer member is located in a gap area between the padding member and the fan module;

[0049] The buffer member is elastically supported between the cushion member and a connection between the first side plate and the fan, or the buffer member is elastically supported between the cushion member and a connection between the second side plate and the fan.

[0050] It is understandable that by providing a spacer in the gap area between the first cover plate and the fan module, and by fixing the spacer to the first cover plate, the first cover plate can provide good installation stability for the spacer. The spacer can extend from the first cover plate to a position close to the fan module, and the buffer is connected between the spacer and the fan module, so that the spacer and the buffer cooperate to apply pressure to the fan module from the opposite direction of the third direction, further realizing the vertical limit fixation between the fan mounting plate and the fan module. By limiting the fan mounting plate and the fan module in the vertical direction, the fan module can be prevented from slipping off the fan mounting plate, and the reliability is better.

[0051] In addition, the buffer can absorb the gap and deformation deviation between the pad and the fan module, so that the pad and the fan module have good stability. During the assembly, transportation, and maintenance of the electronic equipment, the buffer has good buffering performance and can provide shock-absorbing protection for the pad and the fan module, thereby avoiding damage to the pad and the fan module caused by direct collision, and has better reliability.

[0052] In a possible implementation, the cushioning member includes a frame, a first folded edge and a second folded edge, the first folded edge and the second folded edge are respectively connected to opposite sides of the frame, and the frame is fixedly connected to the first cover plate via the first folded edge and the second folded edge.

[0053] In a possible implementation manner, a receiving cavity is provided on a surface of the frame body facing away from the first cover plate, and part of the buffer member is located in the receiving cavity.

[0054] It can be understood that by providing a receiving cavity on the frame and arranging part of the buffer component in the receiving cavity, the receiving cavity can provide a mounting position for the buffer component, which is convenient for quickly positioning and aligning the buffer component and the padding component during the assembly process of the electronic device. This arrangement can also enable the buffer structure to have better installation stability and reliability, so that the buffer component is not easy to slip off the padding component during the process of the first cover plate being removed from the box body or the first cover plate being installed on the box body.

[0094] Under this setting, the various parts of the mounting plate body 41 can present a stepped distribution with height differences in the third direction Z, so that the mounting plate body 41 as a whole can be fixedly connected to the first bottom plate 14 of the chassis 10 only by contacting a relatively small number of parts of the mounting plate body 41 with the first bottom plate 14 of the chassis 10. The rest of the mounting plate body 41 can be suspended relative to the first bottom plate 14 of the chassis 10, so that the board surface area in contact with the first bottom plate 14 of the chassis 10 can be reduced on the basis of ensuring the connection strength between the mounting plate body 41 and the first bottom plate 14 of the chassis 10, and the space for other structural parts arranged on the first bottom plate 14 of the chassis 10 can be maximized, which is conducive to improving the space utilization of the electronic device 100. Exemplarily, the gap area between the rest of the mounting plate body 41 and the first bottom plate 14 of the chassis 10 can be the wiring space of the electronic device 100.

[0095] In this embodiment, the first mounting portion 413 can be mounted to the first bottom plate 14 of the chassis 10, thereby achieving a fixed connection between the mounting plate body 41 and the first bottom plate 14 of the chassis 10. The second mounting portion 414 can be used to mount the fan control board 30. The third mounting portion 415 can be used to mount multiple fan modules 20. Under this setting, the relative positions of the various mounting portions in the fan mounting plate 40 can be reasonably arranged, so that the first mounting portion 413 of the fan mounting plate 40 is connected to the first bottom plate 14 of the chassis 10, the second mounting portion 414 of the fan mounting plate 40 is connected to the fan control board 30, and the third mounting portion 415 of the fan mounting plate 40 is connected to multiple fan modules 20, so that the fan mounting plate 40 can be divided into three independent functional areas. That is, the fan mounting plate 40 can integrate multiple functional areas with different functions, so that the use performance of the fan mounting plate 40 can be diversified, which is conducive to the multi-scenario application of the fan mounting plate 40.

[0096] Please refer to Figure 5 and Figure 6 , the first limiting structure 42 is located at the third mounting portion 415 of the mounting plate body 41. One end of the first limiting structure 42 is connected to the third mounting portion 415 of the mounting plate body 41, and the other end of the first limiting structure 42 extends in a direction away from the mounting plate body 41, so that the first limiting structure 42 presents a structural setting protruding from the mounting plate body 41. Exemplarily, the first limiting structure 42 can be a pin.

[0097] In a possible implementation, the end surface of the other end of the first limiting structure 42 may be a curved surface. It is understandable that the other end of the first limiting structure 42 is the end connected to the fan module 20. By setting the end surface of the other end of the first limiting structure 42 as a curved surface, the other end of the first limiting structure 42 can be curved, which is beneficial to reduce the possibility of scratching with other structural parts in the fan module 20 when the first limiting structure 42 is connected to the second limiting structure 224 of the fan module 20, thereby improving the working reliability of the electronic device 100.

[0098] The outer surface of the first limiting structure 42 is provided with a groove 421, and the groove 421 is arranged near one end of the first limiting structure 42 away from the mounting plate body 41, and the groove 421 is recessed from the outer surface of the first limiting structure 42 in the direction of the center line of the first limiting structure 42. The groove 421 is arranged around the circumferential direction of the first limiting structure 42, that is, the groove 421 is an annular groove. It can be understood that by arranging the groove 421 on the outer surface of the first limiting structure 42, the outer surface of the first limiting structure 42 can be made to present an uneven undulating shape, and when the first limiting structure 42 is connected to the second limiting structure 224 of the fan module 20, part of the second limiting structure 224 of the fan module 20 can be accommodated in the groove 421 of the first limiting structure 42, so as to achieve the locking of the first limiting structure 42 and the second limiting structure 224 of the fan module 20.

[0099] In a possible implementation, the cross-sectional width of the groove 421 along the third direction Z gradually decreases from the outer surface of the first limiting structure 42 to the direction of the center line of the first limiting structure 42. Under this setting, the cross-sectional shape of the groove 421 along the third direction Z can be a trumpet shape with a large outside and a small inside. When the trumpet-shaped groove 421 is connected to the second limiting structure 224 of the fan module 20, the inner wall surface of the groove 421 can serve as a guiding slope that can provide a guiding effect for the second limiting structure 224, thereby guiding the second limiting structure 224 to quickly align with the first limiting structure 42, so that the first limiting structure 42 and the second limiting structure 224 of the fan module 20 can be quickly plugged in and out, and the reliability is better.

[0100] In another possible implementation, the cross-sectional width of the groove 421 along the third direction Z is equal everywhere from the outer surface of the first limiting structure 42 to the center line of the first limiting structure 42. In this configuration, the cross-sectional shape of the groove 421 along the third direction Z can be a rectangular shape with uniform width.

[0101] Please refer to Figure 6 and Figure 7 , Figure 7 yes Figure 1The fan mounting plate 40 of the electronic device 100 is shown in another perspective structural diagram. The number of the first limiting structures 42 can be multiple, and the multiple first limiting structures 42 are spaced apart on the third mounting portion 415 of the mounting plate body 41, and each first limiting structure 42 is used to connect with a second limiting structure 224 of the fan module 20 to achieve a fixed connection between the fan mounting plate 40 and the fan module 20. For example, the number of the first limiting structures 42 can be ten, with Figure 7 The two first limiting structures 42 framed by a dotted frame are grouped into five groups. The two first limiting structures 42 located in the same dotted frame can be fixedly connected to the same fan module 20. The ten first limiting structures 42 can enable the fan mounting plate 40 to be connected to the five fan modules 20, so that multiple fan modules 20 can be arranged on the same fan mounting plate 40, realizing a one-to-many correspondence relationship of one fan mounting plate 40 to multiple fan modules 20, which is beneficial to saving the material cost and assembly process of the electronic device 100. Of course, in other embodiments, one fan mounting plate 40 may correspond to one fan module 20, and the embodiments of the present application do not strictly limit this.

[0102] Please refer to Figure 4 and Figure 8 , Figure 8 yes Figure 2 A schematic diagram of the structure of multiple fan modules 20 of the electronic device 100 and the fan mounting plate 40 is shown. Multiple fan modules 20 are mounted on the third mounting portion 415 of the fan mounting plate 40, and multiple fan modules 20 are arranged in sequence along the second direction Y. Exemplarily, the wind in the electronic device 100 can flow along the first direction X. The number of fan modules 20 can be five, and the specifications of the fan module 20 can be 80mm (X dimension along the first direction) * 80mm (Y dimension along the second direction) * 80mm (Z dimension along the third direction).

[0103] The following will only take the structure of a fan module 20 as an example to explain in detail the specific structure of the fan module 20 and the connection relationship between the fan module 20 and the fan mounting plate 40. In the absence of conflict, the following improvements on the structure of a fan module 20 can be applied to other fan modules 20 of the electronic device 100.

[0104] Please refer to Fig. 9 , Fig.10 and Fig.11 , Fig. 9 yes Figure 1 The structure diagram of a fan module 20 of the electronic device 100 is shown in FIG. Fig.10 yes Fig. 9The fan module 20 is an exploded schematic diagram. The fan module 20 is located in the receiving space W. The fan module 20 may include a fan 21 and a fan frame 22 . The fan 21 is fixed to the fan frame 22 .

[0105] The fan 21 may include a fan body 211, a first fixing plate 212, and a second fixing plate 213. The fan body 211 may be columnar, the first fixing plate 212 and the second fixing plate 213 are respectively connected to both sides of the fan body 211, and the first fixing plate 212 and the second fixing plate 213 are arranged opposite to each other in the first direction X. The opposite ends of the fan body 211 along the first direction X are respectively flush with the opposite ends of the first fixing plate 212 along the first direction X, and the opposite ends of the fan body 211 along the second direction Y are respectively flush with the opposite ends of the first fixing plate 212 along the second direction Y. Along the circumferential direction of the fan 21, the circumference of the fan body 211 is smaller than the circumference of the first fixing plate 212. The orthographic projection of the fan body 211 on the first fixing plate 212 completely falls on the first fixing plate 212. Furthermore, the opposite ends of the fan body 211 along the first direction X are respectively flush with the opposite ends of the second fixing plate 213 along the first direction X, and the opposite ends of the fan body 211 along the second direction Y are respectively flush with the opposite ends of the second fixing plate 213 along the second direction Y. Along the circumferential direction of the fan 21, the circumference of the fan body 211 is smaller than the circumference of the second fixing plate 213. The orthographic projection of the fan body 211 on the second fixing plate 213 completely falls on the second fixing plate 213. The fan body 211, the first fixing plate 212 and the second fixing plate 213 cooperate to form an installation space Q, and the installation space Q is an arc-shaped space recessed inward from the outer surface of the fan 21. Exemplarily, there can be four installation spaces Q, and each installation space Q is arranged at the connection between two adjacent side portions in four side portions of the fan 21 connected in sequence.

[0106] Under this arrangement, among the four side portions of the fan 21 connected in sequence, at the connection point of any two adjacent side portions, the fan body 211 will be recessed inwardly relative to the first fixing plate 212 and the second fixing plate 213, so that four inwardly recessed arc-shaped spaces (installation spaces Q) will be formed around the fan 21. This arc-shaped space can provide a certain amount of installation space for accommodating other structural components in the fan 21.

[0107] In the embodiment of the present application, the number of the fans 21 may be one or more. When the number of the fans 21 is multiple, the multiple fans 21 are arranged in sequence along the first direction X. For example, Fig. 9 and Fig.10 As shown, the number of the fans 21 may be two, and the two fans 21 are arranged in sequence along the first direction X, and the second fixing plate 213 of one fan 21 is attached back to back to the second fixing plate 213 of the other fan 21 .

[0108] Please refer to Fig. 9 and Fig.11 , Fig.11 yes Fig. 9 The fan frame 22 of the fan module 20 is shown as a partial structural diagram. The fan frame 22 may include a second bottom plate 221 , a first side plate 222 , a second side plate 223 and a second limiting structure 224 .

[0109] The second bottom plate 221 is detachably connected to the fan mounting plate 40 and is located on the side of the fan mounting plate 40 away from the first bottom plate 14. Specifically, the second bottom plate 221 can be fixed to the third mounting portion 415 of the fan mounting plate 40, and can also be detached from the third mounting portion 415 of the fan mounting plate 40. When the second bottom plate 221 is fixedly connected to the third mounting portion 415 of the fan mounting plate 40, the fan module 20 and the fan mounting plate 40 are relatively fixed. The second bottom plate 221 may include a first surface 2211 and a second surface 2212 that are arranged opposite to each other. The first surface 2211 of the second bottom plate 221 is a surface of the second bottom plate 221 that abuts against the mounting plate body 41, and the second surface 2212 of the second bottom plate 221 is a surface of the second bottom plate 221 that abuts against the fan 21. The first side plate 222 and the second side plate 223 are respectively connected to the two sides of the second bottom plate 221, and the first side plate 222 and the second side plate 223 are arranged relatively along the second direction Y.

[0110] Exemplarily, when there are two fans 21, the two fans 21 are arranged in sequence along the first direction X, and are both fixedly connected to the fan frame 22. Specifically, the first side plate 222 of the fan frame 22 is fixedly connected to the first fixing plate 212 of one fan 21, the second side plate 223 of the fan frame 22 is fixedly connected to the second fixing plate 213 of the other fan 21, and the second fixing plate 213 of one fan 21 abuts against the second fixing plate 213 of the other fan 21. The first side plate 222, the second side plate 223, and the second bottom plate 221 cooperate to fix the two fans 21.

[0111] It is understandable that, compared with the prior art, at least five of the six sides of the fan need to be fixed, resulting in a larger module volume of the fan module. In the embodiment of the present application, by making the second bottom plate 221 cooperate with the first side plate 222 and the second side plate 223 to fix the fan 21, three of the six sides of the fan 21 can be fixed, and the fixed connection between the fan frame 22 and the fan 21 can be achieved by fixing three of the six sides of the fan 21, so that on the basis of satisfying the connection strength between the fan frame 22 and the fan 21, the space occupied by the fan frame 22 due to the need to fix multiple sides of the fan 21 can be released, the space occupied by the fan frame 22 can be reduced, and the volume of the fan module 20 can be reduced to the maximum extent, so that the fan module 20 can be further miniaturized.

[0112] In addition, since the first side plate 222 and the second side plate 223 are relatively arranged only in the length direction (first direction X) of the electronic device 100, the fan module 20 can have a smaller width dimension in the width direction (second direction Y) of the electronic device 100, so that this part of the space can be vacated and as many fan modules 20 as possible can be arranged in the limited space layout in the electronic device 100. On the basis of ensuring that the electronic device 100 has good working performance, increasing the number of fan modules 20 can reduce the adverse effects on the selection of the fan module 20, further improve the heat dissipation performance of the electronic device 100, and achieve good heat distribution performance of the electronic device 100.

[0113] Please refer to Fig. 9 , Fig.11 and Fig.12 , Fig.12 is along Fig.11 The second limiting structure 224 is connected to the second bottom plate 221, and the second limiting structure 224 is protruding relative to the second surface 2212 of the second bottom plate 221. The fan frame 22 can be fixed on the fan mounting plate 40 by the cooperation between the second limiting structure 224 and the first limiting structure 42. Exemplarily, the second limiting structure 224 can be a plastic part with a certain elasticity.

[0114] The second limiting structure 224 has a plugging hole 2241, which penetrates the second limiting structure 224 and the second bottom plate 221 along the height direction of the electronic device 100. The plugging hole 2241 is used to be plugged with the first limiting structure 42 of the fan mounting plate 40, thereby achieving a fixed connection between the fan mounting plate 40 and the fan module 20. The inner wall of the plugging hole 2241 is provided with a protrusion 2242, which is arranged around the circumferential direction of the plugging hole 2241, that is, the protrusion 2242 is an annular protrusion. It can be understood that by providing a protrusion 2242 on the inner wall of the plug-in hole 2241, the inner wall of the plug-in hole 2241 can be made to present an uneven undulating shape, and when the second limiting structure 224 is connected to the first limiting structure 42 of the fan mounting plate 40, part of the protrusion 2242 can be accommodated in the groove 421 of the first limiting structure 42, thereby realizing the locking of the second limiting structure 224 and the first limiting structure 42 of the fan mounting plate 40.

[0115] In a possible implementation, the plug hole 2241 may include a first hole 2243, a second hole 2244, and a third hole 2245, the third hole 2245 is connected between the first hole 2243 and the second hole 2244, and the third hole 2245 is closer to the second bottom plate 221 relative to the second hole 2244. In the third direction Z, the first hole 2243, the second hole 2244, and the third hole 2245 are arranged in sequence, and the protrusion 2242 is protruded from the hole wall of the second hole 2244.

[0116] In this embodiment, the cross-sectional width of the first hole 2243 along the height direction of the second limiting structure 224 (i.e., the third direction Z) gradually decreases from the second bottom plate 221 to the direction of the fan 21. It can be understood that in the process of connecting the second limiting structure 224 with the first limiting structure 42, the first hole 2243 will be the first hole-type structure in the plug-in hole 2241 to contact the first limiting structure 42. By setting the hole wall of the first hole 2243 as an inclined surface inclined relative to the first direction X, the hole wall of the first hole 2243 can be used as a guiding inclined surface to form a trumpet-shaped expansion shape at the outer end of the first hole 2243, wherein the outer end of the first hole 2243 refers to the end of the first hole 2243 close to the first surface 2211. The shape setting of the first hole 2243 can provide a certain tolerance space for the first limiting structure 42. Even if the first limiting structure 42 is not aligned with the center of the plug-in hole 2241, it can slide into the plug-in hole 2241 under the guidance of the first hole 2243, thereby further improving the plug-in efficiency and plug-in success rate of the first limiting structure 42 and the second limiting structure 224.

[0117] In this embodiment, the cross-sectional width of the second hole 2244 along the height direction of the second limiting structure 224 (i.e., the third direction Z) gradually increases from the second bottom plate 221 to the direction of the fan 21. It can be understood that in the process of connecting the second limiting structure 224 with the first limiting structure 42, the second hole 2244 will serve as the last hole-like structure in the plug-in hole 2241 to contact the first limiting structure 42. By setting the hole wall of the second hole 2244 as an inclined surface inclined relative to the first direction X, the hole wall of the second hole 2244 can be used as a guiding inclined surface to form a trumpet-shaped expansion shape at the outer end of the second hole 2244, wherein the outer end of the second hole 2244 refers to the end of the second hole 2244 away from the second surface 2212. The shape setting of the second hole 2244 can provide a guiding effect for the first limiting structure 42, so that the first limiting structure 42 can pass through the plug-in hole 2241.

[0118] In a possible application scenario, please refer to Figure 7 and Fig.13 , Fig.13 yes Fig.11 The fan frame 22 is shown in FIG. Fig.13It is a top view schematic diagram of the fan frame 22. The number of the second limiting structures 224 can be two, and the two second limiting structures 224 are respectively located on the opposite sides of the second bottom plate 221 along the second direction Y, and the two second limiting structures 224 are staggered along the first direction X, one second limiting structure 224 is close to the first side plate 222, and the other second limiting structure 224 is close to the second side plate 223. In other words, the two second limiting structures 224 are set along the diagonal of the second bottom plate 221. One second limiting structure 224 is located in the installation space Q of one fan 21, and the other second limiting structure 224 is located in the installation space Q of another fan 21. The two second limiting structures 224 in each fan module 20 are arranged in parallel with each other. Figure 7 The two first limiting structures 42 in a dotted frame on the middle fan mounting plate 40 are connected respectively, so as to realize the fixed connection between the fan mounting plate 40 and a fan module 20 .

[0119] It should be noted that the number of the second limiting structures 224 is not limited to two, it can be one or more than two, and their positions can also be arranged accordingly according to the actual application requirements of the electronic device 100. It is only necessary to satisfy the correspondence between one second limiting structure 224 and one first limiting structure 42. The embodiments of the present application do not impose strict restrictions on the number and specific setting positions of the second limiting structures 224.

[0120] For a possible implementation, see Fig.14 , Fig.14 is along Figure 8 The cross-sectional schematic diagram obtained by cutting along the cutting line BB shown. In the embodiment of the present application, when the first limiting structure 42 is inserted into the plug hole 2241 of the second limiting structure 224, the first limiting structure 42 passes through the plug hole 2241 of the second limiting structure 224, and the end of the first limiting structure 42 away from the mounting plate body 41 is protruded relative to the second limiting structure 224, and the first limiting structure 42 cooperates with the second limiting structure 224 to fix the second bottom plate 221 and the fan mounting plate 40. Among them, when the first limiting structure 42 is inserted into the plug hole 2241 of the second limiting structure 224, at least part of the protrusion 2242 is located in the groove 421.

[0121] It is understandable that by plugging the first limiting structure 42 of the fan mounting plate 40 with the second limiting structure 224 of the fan module 20, a clamping connection between the first limiting structure 42 and the second limiting structure 224 can be achieved, thereby achieving the limiting fixation of the fan mounting plate 40 and the fan module 20 in the vertical direction (i.e., the third direction Z). By limiting the fan mounting plate 40 and the fan module 20 in the vertical direction, the fan mounting plate 40 and the fan module 20 can be fixedly connected without occupying the horizontal space, and this part of the space can be released to set a larger number of fan modules 20, which is conducive to improving the overall heat dissipation performance of the electronic device 100.

[0122] In a possible implementation, Fig.11 As shown, the second limiting structure 224 has a first notch 2246, the first notch 2246 penetrates the second limiting structure 224 along the first direction X, and the first notch 2246 is connected to the plug hole 2241. Exemplarily, the number of the first notch 2246 can be two, and the two first notches 2246 are arranged opposite to each other in the first direction X, and are both connected to the plug hole 2241. It can be understood that the setting of the first notch 2246 can provide a certain deformation space for the second limiting structure 224 during the plugging process between the first limiting structure 42 and the second limiting structure 224, facilitate the deformation of the second limiting structure 224, and increase the elasticity of the second limiting structure 224.

[0123] Please refer to Fig. 9 and Fig.14 In the embodiment of the present application, the fan body 211, the first fixing plate 212 and the second fixing plate 213 are all in contact with the second bottom plate 221. The second limiting structure 224 is located in the installation space Q formed by the fan body 211, the first fixing plate 212 and the second fixing plate 213. It can be understood that the installation space Q formed by the fan body 211, the first fixing plate 212 and the second fixing plate 213 is an idle space in the fan module 20. The second limiting structure 224 is arranged in this installation space Q, which can avoid interfering with the other structures in the fan module 20, and make full use of the idle space in the fan module 20, effectively improving the space utilization rate of the fan module 20. Exemplarily, the installation space Q can be an arc-shaped space.

[0124] In a possible implementation, please refer to Fig. 9 , Fig.10 and Fig.11The first fixing plate 212 of the fan 21 may be provided with a plurality of mounting holes 214, which are spaced apart on the first fixing plate 212, and each mounting hole 214 penetrates the first fixing plate 212 along the thickness direction (i.e., the first direction X) of the first fixing plate 212. For example, the plurality of mounting holes 214 may be spaced apart at one end of the first fixing plate 212 away from the second bottom plate 221. The number of mounting holes 214 may be two, and the two mounting holes 214 are respectively distributed at two vertex corners of one end of the first fixing plate 212 away from the second bottom plate 221.

[0125] In this embodiment, the fan frame 22 may further include a plurality of third limiting structures 225, which are spaced apart on the surface of the first side plate 222 facing the second side plate 223 and the surface of the second side plate 223 facing the first side plate 222. For example, the third limiting structures 225 may be plastic parts with a certain elasticity.

[0126] One end of the column 2251 close to the first side plate 222 is connected to the surface of the first side plate 222 facing the second side plate 223, and the other end of the column 2251 close to the first side plate 222 is connected to the clamping portion 2252. One end of the column 2251 close to the second side plate 223 is connected to the surface of the second side plate 223 facing the first side plate 222, and the other end of the column 2251 close to the second side plate 223 is connected to the clamping portion 2252.

[0127] For example, a plurality of third limiting structures 225 may be distributed at intervals at one end of the first fixing plate 212 away from the second bottom plate 221 and at one end of the second fixing plate 213 away from the second bottom plate 221. The number of the third limiting structures 225 may be four, two third limiting structures 225 are respectively distributed at two vertex corners of one end of the first fixing plate 212 away from the second bottom plate 221, and the other two third limiting structures 225 are respectively distributed at two vertex corners of one end of the second fixing plate 213 away from the second bottom plate 221. Fig.11 As shown, the third limiting structure 225 has a second notch 2253, and the second notch 2253 penetrates the second limiting structure 224 along the first direction X. It can be understood that the provision of the second notch 2253 can provide a certain deformation space for the third limiting structure 225 during the plugging process between the third limiting structure 225 and the mounting hole 214, facilitate the deformation of the third limiting structure 225, and increase the elasticity of the third limiting structure 225.

[0128] When the plurality of third limiting structures 225 are inserted into the plurality of mounting holes 214, a column 2251 close to the first side plate 222 passes through a mounting hole 214 of the first fixing plate 212 affixed to the first side plate 222, and the clamping portion 2252 connected thereto abuts against the first fixing plate 212 affixed to the first side plate 222, so as to fix the fan frame 22 and the fan 21. And / or, a column 2251 close to the second side plate 223 passes through a mounting hole 214 of the first fixing plate 212 affixed to the second side plate 223, and the clamping portion 2252 connected thereto abuts against the first fixing plate 212 affixed to the second side plate 223, so as to fix the fan frame 22 and the fan 21.

[0129] It is understandable that, by making the fan frame 22 include the third limiting structure 225, and making the third limiting structure 225 of the fan frame 22 and the mounting hole 214 of the fan 21 clamped and fixed, the third limiting structure 225 of the fan frame 22 can be matched with the mounting hole 214 of the fan 21, so as to achieve the limiting fixation between the fan frame 22 and the fan 21 in the horizontal direction (i.e., the first direction X and the opposite direction of the first direction X). In the horizontal direction, the fan mounting plate 40 and the fan module 20 are mutually limited, and the fan 21 can also be prevented from slipping off the fan frame 22, and the reliability is better.

[0130] For a possible implementation, see Fig.15 , Fig.15 is along Figure 1 The section line CC shown is a partial cross-sectional schematic diagram obtained by cutting. The electronic device 100 may also include a pad 50 and a buffer 60. The pad 50 may be connected to the first cover plate 12 of the chassis 10, thereby occupying a certain vertical space between the first cover plate 12 of the chassis 10 and the plurality of fan modules 20, so that the first cover plate 12 of the chassis 10 can cooperate with the fan mounting plate 40 to limit the movement of the plurality of fan modules 20 from two opposite directions in the vertical space in the chassis 10, further ensuring that the positions of the plurality of fan modules 20 will not change when they are fixed in the chassis 10. The buffer 60 may be connected between the pad 50 and the plurality of fan modules 20, thereby absorbing the gap between the pad 50 and the plurality of fan modules 20, and preventing the plurality of fan modules 20 from moving, slipping off the fan mounting plate 40, and other problems.

[0131] Specifically, the padding member 50 is connected to the surface of the first cover plate 12 facing the first bottom plate 14, and the padding member 50 extends along the second direction Y. The padding member 50 extends from the third side plate 15 of the box body 11 to the fourth side plate 16 of the box body 11 in the second direction Y. The buffer member 60 is located in the gap area between the padding member 50 and the fan module 20, and the buffer member 60 extends along the second direction Y. The buffer member 60 extends from one end of the plurality of fan modules 20 to the other end of the plurality of fan modules 20 in the second direction Y. The buffer member 60 elastically abuts against the padding member 50 and the connection between the first side plate 222 and the fan 21, or the buffer member 60 elastically abuts between the padding member 50 and the connection between the second side plate 223 and the fan 21. It should be noted that the following description will be given assuming that both the raising member 50 and the buffer member 60 are located in the gap area between the first cover plate 12 and the multiple fan modules 20. The limiting and fixing effects of the raising member 50 and the buffer member 60 are applicable to the multiple fan modules 20, that is, one raising member 50 and one buffer member 60 correspond to multiple fan modules 20. In other embodiments, one fan module 20 may also correspond to one raising member 50 and one buffer member 60. The embodiments of the present application do not impose strict restrictions on this.

[0132] Exemplarily, the compression amount of the buffer 60 can be 30%-50% (including the endpoint values ​​30% and 50%, and the tolerance range is allowed). The buffer 60 can be foam, rubber, waterproof rubber pad, etc. Of course, the buffer 60 is not limited to the types listed above. The buffer structure that can meet the conditions of continuous, having a certain thickness, and being able to absorb deformation of the buffer material is within the scope of protection claimed in the embodiments of the present application.

[0133] It is understandable that by setting the padding member 50 in the gap area between the first cover plate 12 and the fan module 20 and fixing the padding member 50 to the first cover plate 12, the first cover plate 12 can provide good installation stability for the padding member 50. The padding member 50 can extend from the first cover plate 12 to a position close to the fan module 20, and the buffer member 60 is connected between the padding member 50 and the fan module 20, so that the padding member 50 and the buffer member 60 can cooperate to apply pressure to the fan module 20 from the opposite direction of the third direction Z, and further realize the vertical limit fixation between the fan mounting plate 40 and the fan module 20 (i.e., the opposite direction of the third direction Z). By limiting the fan mounting plate 40 and the fan module 20 in the vertical direction, the fan module 20 can be prevented from slipping off the fan mounting plate 40, and the reliability is better.

[0134] In addition, the buffer member 60 can absorb the gap and deformation deviation between the padding member 50 and the fan module 20, so that the padding member 50 and the fan module 20 have good stability. During the assembly, transportation, and maintenance of the electronic device 100, the buffer member 60 has good buffering performance and can provide shock-absorbing protection for the padding member 50 and the fan module 20, thereby avoiding damage to the padding member 50 and the fan module 20 caused by direct collision, and has better reliability.

[0135] In this embodiment, please refer to Fig.16 and Fig.17 , Fig.16 yes Fig.15 The structure diagram of the heightening member 50 of the electronic device 100 is shown at an angle. Fig.17 yes Fig.15 A schematic structural diagram of the cushioning member 50 of the electronic device 100 shown in FIG. 1 is another angle diagram. The cushioning member 50 may include a frame 51, a first folded edge 52, and a second folded edge 53. The first folded edge 52 extends along the second direction Y, and extends from the third side panel 15 of the box body 11 to the fourth side panel 16 of the box body 11. The second folded edge 53 extends along the second direction Y, and extends from the third side panel 15 of the box body 11 to the fourth side panel 16 of the box body 11. The frame 51 is a hollow frame structure, and the middle frame may be in a door-like shape. The frame 51 extends along the second direction Y, and extends from the third side panel 15 of the box body 11 to the fourth side panel 16 of the box body 11. As shown in FIG. Fig.15 As shown, the cross-sectional width of the frame body 51 along the third direction Z can gradually increase from the first bottom plate 14 to the first cover plate 12. The first folded edge 52 and the second folded edge 53 are respectively connected to the opposite sides of the frame body 51 along the first direction X, and the frame body 51 is fixedly connected to the first cover plate 12 through the first folded edge 52 and the second folded edge 53.

[0136] In one possible embodiment, a receiving cavity 54 is provided on the surface of the frame body 51 facing away from the first cover plate 12. The receiving cavity 54 is recessed relative to the surface of the frame body 51 facing away from the first cover plate 12 and protrudes relative to the surface of the frame body 51 facing the first cover plate 12. Part of the buffer member 60 is located in the receiving cavity 54.

[0137] It can be understood that by providing a receiving cavity 54 on the frame 51 and partially providing the buffer member 60 in the receiving cavity 54, the receiving cavity 54 can provide a mounting position for the buffer member 60, so that the buffer member 60 can be quickly positioned and aligned with the pad member 50 during the assembly process of the electronic device 100. This arrangement can also enable the buffer structure to have better installation stability and reliability, so that the buffer member 60 is not easy to slip off the pad member 50 during the process of the first cover plate 12 being removed from the box body 11 or the first cover plate 12 being installed on the box body 11.

[0138] In a possible implementation, please refer to Fig.11 and Fig.18 , Fig.18 yes Fig.11 A schematic structural diagram of the fan frame 22 from another angle is shown.

[0139] like Fig.11 As shown, the fan module 20 may further include a connector 23, which is fixedly connected to the fan frame 21, and the fan module 20 can be electrically connected to the fan control board 30 through the connector 23. Specifically, the connector 23 can be electrically connected to the fan 21, and the connector 23 can also be plugged with a corresponding connector on the fan control board 30, so as to be electrically connected between the fan control board 30 and the fan 21, thereby realizing a current path between the fan module 20 and the fan control board 30, facilitating the fan control board 30 to accurately adjust the speed of multiple fan modules 20, and realizing an upgrade of the heat dissipation capacity of the electronic device 100.

[0140] In this embodiment, the fan frame 22 may further include a connecting structure 226, which is disposed on a side of the first side plate 222 away from the second side plate 223, and the connecting structure 226 extends in the opposite direction of the first direction X. Alternatively, the connecting structure 226 is disposed on a side of the second side plate 223 away from the first side plate 222, and the connecting structure 226 extends in the first direction X. The connecting structure 226 is provided with a card slot 2261. The connector 23 is fixedly clamped with the connecting structure 226, and a portion of the connector 23 is located in the card slot 2261.

[0141] It is understandable that, by providing the connection structure 226 and connecting the connection structure 226 to the first side plate 222 or the second side plate 223 of the fan frame 22, the connection structure 226 can be used as an extension of the side plate to provide a mounting position for the connector 23, so that the connector 23 can be fixedly connected to the fan frame 22 by being clamped and connected with the connection structure 226. In addition, the provision of the connection structure 226 can also increase the overall structural strength of the fan frame 22, so that the fan frame 22 is not easily deformed.

[0142] In this embodiment, please refer to Figure 2 and Fig.19 , Fig.19 yes Figure 2The fan control board 30 and the fan module 20 of the electronic device 100 are shown as a schematic diagram of the assembly of the fan mounting plate 40. The fan control board 30 is connected to the second mounting portion 414 of the fan mounting plate 40, and the fan control board 30 extends along the second direction Y. The fan control board 30 is electrically connected to multiple fan modules 20. When the fan module 20 is fixedly connected to the third mounting portion 415 of the fan mounting plate 40, the fan control board 30 is located in the gap area between the fan module 20 and the second mounting portion 414, and the fan control board 30 is electrically connected to the fan 21 of the fan module 20 by plugging with the connector 23 of each fan module 20. Exemplarily, the fan control board 30 is a circuit board that can control the opening and closing of multiple fan modules 20. In the first direction X, the fan control board 30 and the padding member 50 can be located on the same side of the fan module 20, or the fan control board 30 and the padding member 50 can be located on different sides of the fan module 20.

[0143] It is understandable that the fan control board 30 can independently control one fan module 20 or multiple fan modules 20 among the multiple fan modules 20, and the fan control board 30 is also electrically connected between the multiple fan modules 20 and the single board, so the multiple fan modules 20 can be finely controlled through the single board. That is, by independently controlling one or more fan modules 20 among the multiple modules, the number of fans 21 that meet the corresponding heat dissipation requirements can be configured according to the temperature in the chassis 10, so as to achieve accurate speed regulation of the fan module 20 and upgrade the heat dissipation capacity.
