Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and particularly relates to a hard disk module and an electronic device. BACKGROUND

[0002] In order to improve competitiveness, current servers, supercomputers and other electronic devices need to be equipped with more hard disks to improve computing speed and storage capacity. The improvement of computing speed and storage capacity easily leads to the increasing power consumption of the hard disks, and the high configuration density in the electronic device easily leads to the decreasing air inlet area of the hard disks. The heat dissipation of the hard disks gradually becomes a bottleneck. SUMMARY

[0003] Embodiments of the present application provide a hard disk module and an electronic device, which can perform good heat dissipation for the hard disk.

[0004] In a first aspect, the present application provides a hard disk module, which comprises:

[0005] a support, which surrounds a receiving space and is used for accommodating a hard disk;

[0006] a base, which has a ventilation cavity, and comprises an end plate, a top plate and a bottom plate, the end plate is connected to one end of the support, the top plate and the bottom plate are respectively connected to opposite sides of the end plate, the top plate has a plurality of first ventilation grooves arranged at intervals, each first ventilation groove is in communication with the ventilation cavity, and / or the bottom plate has a plurality of second ventilation grooves arranged at intervals, each second ventilation groove is in communication with the ventilation cavity.

[0007] It can be understood that when the hard disk module is installed in a case of an electronic device, the case and the top surface of the hard disk form a first air duct. The first air duct is in communication with the first ventilation grooves, so that cold air can flow from the ventilation cavity of the base to the first air duct. The case and the bottom surface of the hard disk form a second air duct to dissipate heat from the top surface of the hard disk. The second air duct is in communication with the second ventilation grooves, so that cold air can flow from the ventilation cavity of the base to the second air duct to dissipate heat from the bottom surface of the hard disk.

[0008] Thus, by setting the first air vent and the second air vent, not only can the cold air enter the first air duct and the second air duct through the first air vent and the second air vent respectively, and the heat of the hard disk is effectively expanded by the air flowing in the first air duct and the second air duct, reducing the thermal resistance and temperature of the hard disk. Also, through the direct contact of the first air duct and the second air duct with the hard disk, the first air duct and the second air duct can fully play their role in temperature equalization, so that the temperature difference of the hard disk at each position is uniform, and the hard disk module as a whole has good heat conduction temperature difference and heat transfer efficiency, effectively improving the heat dissipation performance of the hard disk module. The cold air enters the first air duct through the first air vent and enters the second air duct through the second air vent, and carries the heat generated by the hard disk in the flow of the first air duct and the second air duct to become hot air, which is discharged from the electronic device through the heat dissipation device such as the fan module in the electronic device. The cold and hot air alternately circulates and repeats to complete the uninterrupted heat exchange of the hard disk module, ensuring that the hard disk module always has good heat dissipation performance.

[0009] In a possible implementation, the first air vent extends along a first direction, and the first direction is a length direction of the hard disk module; and / or,

[0010] The second air vent extends along a first direction, and the first direction is a length direction of the hard disk module.

[0011] With this setting, a larger number of first air vents can be arranged on the top plate, and a larger number of second air vents can be arranged on the bottom plate, which is conducive to further improving the heat dissipation performance of the hard disk module.

[0012] In a possible implementation, the first air vent extends along a first direction, and the first direction is a length direction of the hard disk module; and / or,

[0013] The second air vent extends along a first direction, and the first direction is a length direction of the hard disk module.

[0014] In this arrangement, the first air vent and the second air vent can have a longer extension size. On one hand, the longer extension size of the first air vent and the second air vent can layout a larger volume of the first air vent and the second air vent in a limited space, meet the depth requirement inside the hard disk module space, and can flow a larger volume of cold air to the first air vent and the second air vent at a time under the same volume of the air vent cavity, so that more cold air can be blown to the top surface and the bottom surface of the hard disk under a single heat exchange cycle. On the other hand, the first air vent and the second air vent arranged obliquely can reduce the space size of the top plate and the bottom plate in the first direction, and the space released by the oblique placement of the first air vent and the second air vent can correspondingly layout more first air vents and second air vents, thereby maximizing the number of first air vents and second air vents and effectively improving the heat dissipation performance of the hard disk module.

[0015] In a possible implementation, the first air vent includes a first end and a second end, the second end is closer to the support relative to the first end, a length of the first end in a second direction is less than or equal to a length of the second end in the second direction, the second direction is perpendicular to the first direction, and the second direction is a width direction of the hard disk module; and / or,

[0016] The second air vent includes a third end and a fourth end, the fourth end is closer to the support relative to the third end, a length of the third end in a second direction is less than or equal to a length of the fourth end in the second direction, the second direction is perpendicular to the first direction, and the second direction is a width direction of the hard disk module.

[0017] In this arrangement, the length of the first air vent and the second air vent in the second direction changes with the extension direction of the first air vent and the second air vent, so that the first air vent and the second air vent can present a horn shape or a trapezoidal shape, so that the second end of the first air vent and the fourth end of the second air vent play a role of guiding flow, and more cold air can be guided to the top surface and the bottom surface of the hard disk, which is beneficial to improve the overall heat dissipation efficiency of the hard disk module.

[0018] In a possible implementation, the first air vent includes a first opening and a second opening arranged opposite in a third direction, the first opening is arranged on a surface of the top plate facing the air vent cavity, the second opening is arranged on a surface of the top plate away from the air vent cavity, a length of the first opening in the first direction is greater than or equal to a length of the second opening in the first direction, the third direction is perpendicular to the first direction, and the third direction is a height direction of the hard disk module.

[0019] That is, in the direction from the first opening to the second opening, the length of the first ventilation groove in the second direction changes with the extension direction of the first ventilation groove. In this arrangement, the first ventilation groove has a large contact area with the cold air in the ventilation cavity, and can guide more cold air into the first ventilation groove, which is conducive to further improving the heat dissipation performance of the hard disk module.

[0020] And / or, the second ventilation groove includes a third opening and a fourth opening oppositely arranged along a third direction, the third opening is arranged on the surface of the bottom plate facing the ventilation cavity, the fourth opening is arranged on the surface of the bottom plate away from the ventilation cavity, the length of the third opening in the first direction is greater than or equal to the length of the fourth opening in the first direction, the third direction is perpendicular to the first direction, and the third direction is the height direction of the hard disk module.

[0021] That is, in the direction from the third opening to the fourth opening, the length of the second ventilation groove in the second direction changes with the extension direction of the second ventilation groove. In this arrangement, the second ventilation groove has a large contact area with the cold air in the ventilation cavity, and can guide more cold air into the second ventilation groove, which is conducive to further improving the heat dissipation performance of the hard disk module.

[0022] In a possible implementation, the end plate is provided with one or more third ventilation grooves, and the third ventilation grooves are in communication with the ventilation cavity and the accommodation space.

[0023] In this arrangement, the air entering the ventilation cavity can flow into the support through the third ventilation groove, and be divided into two parts in the support, one part flows to the top surface of the hard disk, and the other part flows to the bottom surface of the hard disk, so as to carry the heat of the hard disk during the flow process, complete the heat exchange with the hard disk, and achieve good heat dissipation for the hard disk.

[0024] In a possible implementation, the hard disk module further includes a shielding shell, the shielding shell is arranged on the periphery of the base, and the shielding shell is located between the base and the support.

[0025] The shielding shell can be made of a metal material, or made of a non-metal material and provided with a conductive plating layer on the surface of the non-metal material.

[0065] The specific embodiments of the present application will be clearly described below with reference to the drawings.

[0066] Embodiments of the present application provide a hard disk module and an electronic device.

[0067] The electronic device can be, but is not limited to, a server, a router, a switch, a supercomputer, an AI (Artificial Intelligence) device, etc. For the convenience of understanding, the electronic device will be taken as a server for example below, but it should be understood that it is not limited thereto.

[0068] Please refer to Figure 1A and Figure 1B , Figure 1A is a structural schematic diagram of an angle of an electronic device 200 provided by embodiments of the present application, Figure 1B is a structural schematic diagram of another angle of the electronic device 200 provided by embodiments of the present application. Among them, Figure 1A may be a top view of the electronic device 200, Figure 1B may be Figure 1A the left view of the electronic device 200 shown in the figure.

[0069] The electronic device 200 can include a case 210 and a plurality of hard disk modules 100, and the plurality of hard disk modules 100 are arranged and disposed in the case 210. Among them, the hard disk module 100 can be a removable hard disk module, which can be installed on the case 210 or taken out from the case 210 by plugging and unplugging action. Specifically, the case 210 can have a plurality of mounting slots 220, and the plurality of mounting slots 220 and the plurality of hard disk modules 100 are plugged according to a one-to-one correspondence relationship that one hard disk module 100 corresponds to one mounting slot 220. That is, the plurality of hard disk modules 100 are inserted into the plurality of mounting slots 220 one by one.

[0070] In one possible implementation, as Figure 1A shown, the electronic device 200 can further include a circuit board 230, a chip 240 and a memory stick 250. The circuit board is arranged inside the case 210, and the plurality of hard disk modules 100, the chip 240 and the memory stick 250 are all connected to the circuit board 230 to realize the functions of data exchange, processing or storage of the electronic device 200.

[0071] Exemplarily, the chip 240 can be, but is not limited to, a chip such as a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), a TPU (Tensor Processing Unit), or a hard disk drive, etc. The memory bank 250 can be a DIMM (Dual-Inline-Memory-Modules), such as one or more of a first generation of DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory), a second generation of DDR SDRAM (DDR2 SDRAM), a third generation of DDR SDRAM (DDR3 SDRAM), a fourth generation of DDR SDRAM (DDR4 SDRAM), and a fifth generation of DDR SDRAM (DDR5 SDRAM).

[0072] It should be noted that the number of chips 240 can be configured to be one or more as needed, and the number of memory banks 250 can also be selected according to the actual application scenario. The number, type, etc. of the chip 240 and the memory bank 250 are not strictly limited in the embodiments of the present application.

[0073] Please refer to Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of a hard disk module 100 provided by an embodiment of the present application, Figure 3 is Figure 2 an exploded schematic diagram of the hard disk module 100 shown in FIG. 1.

[0074] In the embodiments of the present application, for the convenience of illustration, the length direction of the hard disk module 100 is the first direction X, the width direction of the hard disk module 100 is the second direction Y, and the height direction of the hard disk module 100 is the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0075] The hard disk module 100 can include a hard disk 10, a bracket 20, a base 30, a shielding shell 40, a wrench 50, a dial 60, and a light guide 70. It should be noted that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the hard disk module 100. In other embodiments of the present application, the hard disk module 100 can include more or fewer components than illustrated, or combine certain components, or split certain components, or different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0076] It can be understood that in the working process of the electronic device 200, the hard disk 10 as a heat generating device will generate a large amount of heat, thereby forming a hot spot at a corresponding position inside the electronic device 200. The temperature of the hot spot is relatively high, and if the heat generated by the hot spot is not effectively dissipated in time, it will directly affect the working performance of the electronic device 200, for example, if the local overheating causes the electronic device 200 to fail. Moreover, the temperature of the chassis 210 at the corresponding position of the hot spot will also be relatively high, causing local overheating of the chassis 210, which seriously affects the working reliability of the electronic device 200. That is, the heat balance of the hard disk 10 will directly affect the working performance of the electronic device 200. Such a hot spot problem is particularly prominent in electronic devices 200 with high computing speed, high storage capacity, and high-density device arrangement, so that the heat dissipation of the hard disk module 100 gradually becomes a bottleneck.

[0077] Please refer to Figure 3 and Figure 4 , Figure 4 is Figure 2 a structural schematic diagram of the hard disk module 100 installed in the chassis 210. Among them, Figure 4 The direction of the arrow in the figure represents the flow direction of the cold air. Specifically, the hard disk 10 can include a top surface 11 and a bottom surface 12 arranged opposite to each other. The top surface 11 of the hard disk 10 and the bottom surface 12 of the hard disk 10 are large surfaces of the hard disk 10 (i.e., the surfaces with the largest area in the hard disk 10). The top surface 11 of the hard disk 10 and the bottom surface 12 of the hard disk 10 are surfaces exposed to the external environment of the hard disk module 100, and when the hard disk module 100 is installed in the chassis 210, the top surface 11 of the hard disk 10 and the chassis 210 form a first air duct W1, and the bottom surface 12 of the hard disk 10 and the chassis 210 form a second air duct W2.

[0078] Based on the above description, it should be understood that the top surface 11 of the hard disk 10 and the bottom surface 12 of the hard disk 10 are effective heat dissipation surfaces of the hard disk 10, and therefore the heat dissipation operation of the hard disk 10 can be focused on heat dissipation of the top surface 11 of the hard disk 10 and the bottom surface 12 of the hard disk 10. Among them, the hard disk 10 can be a mechanical hard disk (Hard Disk Drive, HDD), or the hard disk 10 can also be a solid state disk (Solid State Disk, SSD). Exemplarily, the hard disk 10 can be detachably fixed to the bracket 20, such as through bolt connection or buckle connection, etc.

[0079] Please refer to Figure 5 , Figure 5 is Figure 2A structure schematic view of the bracket 20 of the hard disk module 100 is shown. The bracket 20 can include a first side plate 21, a second side plate 22 and a third side plate 23, the first side plate 21, the second side plate 22 and the third side plate 23 surrounding a receiving space 24 of the bracket 20, the receiving space 24 being used for receiving the hard disk 10.

[0080] Specifically, the first side plate 21 is oppositely arranged with the second side plate 22, the first side plate 21 extending along a first direction X, and the second side plate 22 also extending along the first direction X. The third side plate 23 is connected between the first side plate 21 and the second side plate 22. The third side plate 23 extends along a second direction Y. The third side plate 23 is provided with one or more through holes 231. Specifically, when the third side plate 23 is provided with one through hole 231, the through hole 231 penetrates through the third side plate 23 and communicates with the receiving space 24. When the third side plate 23 is provided with a plurality of through holes 231, the plurality of through holes 231 are arranged at intervals, and the plurality of through holes 231 all penetrate through the third side plate 23 and communicate with the receiving space 24. The diameters of the plurality of through holes 231 can be the same, or the diameters of the plurality of through holes 231 can be different. With this arrangement, the cold air flowing into the hard disk module 100 can directly flow into the receiving space 24 of the bracket 20 opposite the first side plate 21, thereby radiating the hard disk 10 with a shorter heat dissipation path.

[0081] Exemplarily, the bracket 20 can be an integrally formed metal piece. The material of the bracket 20 can be selected from stainless steel materials, such as 304 stainless steel, 302 stainless steel, etc. The bracket 20 can be manufactured by die processing or numerical punching processing. With this arrangement, the bracket 20 can have a smaller thickness size, the space occupied by the bracket 20 is reduced, and thus the size of the hard disk module 100 is reduced, so that more hard disk modules 100 can be arranged inside the electronic device 200 under the premise that the size of the case 210 of the electronic device 200 is unchanged, which is conducive to improving the computing speed and storage capacity of the electronic device 200, and fully adapts to the miniaturization development trend of the hard disk module 100.

[0082] Please refer to Figure 5 and Figure 6 , Figure 6 are Figure 2 A structure schematic view of the hard disk 10 of the hard disk module 100 installed in the bracket 20 of the hard disk module 100 is shown. It can be understood that when the hard disk 10 is fixed in the receiving space 24 of the bracket 20, the first side plate 21 and the second side plate 22 can be arranged in close contact with the hard disk 10, and the third side plate 23 can have a gap H with the hard disk 10. The gap H can divide the cold air entering the inside of the receiving space 24 through the through hole 231 into two parts, one part flowing towards the top surface 11 of the hard disk 10, and the other part flowing towards the bottom surface 12 of the hard disk 10, so as to radiate the hard disk 10.

[0083] In one possible implementation, please refer to Figure 5 and Figure 7 , Figure 7 is Figure 5 the exploded schematic view of the bracket 20. The first side plate 21 and / or the second side plate 22 is provided with a plurality of spring sheets 25, which protrude out of the bracket 20 relative to the first side plate 21 and / or the second side plate 22. Specifically, the spring sheet 25 can include a first connecting section 251, a second connecting section 252, and a third connecting section 253. On the first side plate 21, the first connecting section 251 is fixedly connected to the first side plate 21, the second connecting section 252 is also fixedly connected to the first side plate 21, and the third connecting section 253 is foldably connected between the first connecting section 251 and the third connecting section 253 and is suspended relative to the first side plate 21, and the third connecting section 253 protrudes away from the first side plate 21. On the second side plate 22, the first connecting section 251 is fixedly connected to the second side plate 22, the second connecting section 252 is also fixedly connected to the second side plate 22, and the third connecting section 253 is foldably connected between the first connecting section 251 and the third connecting section 253 and is suspended relative to the second side plate 22, and the third connecting section 253 protrudes away from the second side plate 22.

[0084] In this arrangement, when the hard disk module 100 is installed in the case 210 of the electronic device 200, the spring sheet 25 is compressed between the case 210 and the first side plate 21 and / or the case 210 and the second side plate 22, so that the spring sheet 25 is located in the gap H region between the case 210 and the bracket 20. On the one hand, the spring sheet 25 can support and dampen the bracket 20, which is conducive to improving the anti-vibration parameters of the hard disk module 100 under different vibration frequencies, and the hard disk module 100 has stronger anti-vibration performance and higher working reliability. On the other hand, the arrangement of the spring sheet 25 can reduce the scratching of the bracket 20 and the case 210 during installation and disassembly, thereby effectively preventing the bracket 20 from being damaged due to scratching and protecting the structural integrity of the bracket 20. In addition, the arrangement of the spring sheet 25 is also conducive to enhancing the structural strength of the first side plate 21 and / or the second side plate 22.

[0085] Please refer to Figure 8 , Figure 8 is Figure 2 the structural schematic view of the base 30 of the hard disk module 100. The base 30 can include an end plate 31, a top plate 32, and a bottom plate 33, which surround to form a ventilation cavity 34, which is in communication with the external environment and can allow cold air outside the hard disk module 100 to flow in. The top plate 32 and the bottom plate 33 are oppositely arranged in the third direction Z, and the end plate 31 is connected between the top plate 32 and the bottom plate 33. That is, the top plate 32 and the bottom plate 33 are respectively connected on opposite sides of the end plate 31.

[0086] Please refer to Figure 9 and Figure 10 , Figure 9 is Figure 2 Figure 2 is a schematic view of the structure of the base 30 of the hard disk module 100 mounted on the support 20 of the hard disk module 100, Figure 10 is Figure 2 Figure 3 is a schematic view of the structure of the base 30 of the hard disk module 100 and the hard disk 10 mounted on the support 20 of the hard disk module 100. The end plate 31 is connected to one end of the support 20, and the end plate 31 is arranged opposite to the third side plate 23 of the support 20. In one possible implementation, the end plate 31 further comprises one or more third ventilation grooves 311 in communication with the ventilation cavity 34, and the one or more third ventilation grooves 311 are arranged in correspondence with the one or more through holes 231 on the third side plate 23. Specifically, when the end plate 31 is provided with one third ventilation groove 311, the third ventilation groove 311 penetrates the end plate 31 along the first direction X, and the third ventilation groove 311 can be arranged in correspondence with and in communication with one through hole 231 on the third side plate 23, so that the third ventilation groove 311 is in communication with the containing space 24 of the support 20. When the end plate 31 is provided with a plurality of third ventilation grooves 311, the plurality of third ventilation grooves 311 are arranged at intervals, and the plurality of third ventilation grooves 311 all penetrate the end plate 31 along the first direction X. The plurality of third ventilation grooves 311 are in one-to-one correspondence with the plurality of through holes 231 arranged on the third side plate 23, so that the plurality of third ventilation grooves 311 are in communication with the containing space 24 of the support 20. In this arrangement, the air entering the ventilation cavity 34 can flow into the support 20 through the third ventilation grooves 311 and the through holes 231, and be divided into two parts in the support 20, one part flows to the top surface 11 of the hard disk 10, and the other part flows to the bottom surface 12 of the hard disk 10, so as to carry the heat of the hard disk 10 in the flow process, complete the heat exchange with the hard disk 10, and achieve good heat dissipation for the hard disk 10.

[0087] It can be understood that, in order to adapt to the development trend of miniaturization of the hard disk module 100, the gap H between the third side plate 23 and the hard disk 10 will be gradually compressed, and the distance between the third side plate 23 and the hard disk 10 will become smaller after compression, thereby causing the air resistance of the hard disk 10 to be relatively large, and the hard disk 10 to be difficult to dissipate heat.

[0088] Based on this, in this application, additional ventilation slots can be formed on the top plate 32 and / or the bottom plate 33 to provide an outward heat dissipation path for the side of the base 30. Specifically, ventilation slots on the top plate 32 can dissipate heat from the top surface 11 of the hard drive 10, and ventilation slots on the bottom plate 32 can dissipate heat from the bottom surface 12 of the hard drive 10. This effectively reduces the air resistance of the hard drive module 100 and improves its heat dissipation performance, adapting to the trend of miniaturization in the hard drive module 100. It should be noted that in this application, the formation of ventilation slots on the top plate 32 and / or the bottom plate 33 includes the following scenarios: no additional ventilation slots are provided on the bottom plate 33, only on the top plate 32; no additional ventilation slots are provided on the top plate 32, only on the bottom plate 33; and ventilation slots are provided on both the top plate 32 and the bottom plate 33. The following explanation will take the example of ventilation slots on both the top plate 32 and the bottom plate 33. It should be understood that this is not a limitation.

[0089] Please refer to the following: Figure 10 and Figure 11 , Figure 11 It is along Figure 10 The diagram shows a cross-sectional view of the hard drive module 100 installed in the chassis 210, obtained by cutting along section line AA. Figure 11 The direction of the arrow indicates the direction of cold air flow. The top plate 32 is connected to one side of the end plate 31, and the top plate 32 may have multiple spaced-apart first ventilation slots 321. Each first ventilation slot 321 penetrates the top plate 32 along a third direction Z. Each first ventilation slot 321 connects to the ventilation cavity 34 and the external environment, so that the air entering the ventilation cavity 34 flows to the top surface 11 of the hard disk 10 after passing through multiple first ventilation slots 321.

[0090] Alternatively, the first ventilation slot 321 may be located only in the top plate 32, or, as Figure 11 As shown, the first ventilation slot 321 can be located on the top plate 32 and the end plate 31, that is, the first ventilation slot 321 can extend from the top plate 32 to the end plate 31.

[0091] It should be noted that the slot shape of each first ventilation slot 321, the size of each first ventilation slot 321, the setting position of each first ventilation slot 321, the spacing between two adjacent first ventilation slots 321, and the actual number of multiple first ventilation slots 321 can all be selected according to the actual application scenario, and there are no strict restrictions on them.

[0092] Understandably, when the hard drive module 100 is installed in the chassis 210 of the electronic device 200, the chassis 210 and the top surface 11 of the hard drive 10 form a first airflow channel W1. The first airflow channel W1 is connected to the first ventilation slot 321, allowing cool air to flow from the ventilation cavity 34 of the base 30 to the first airflow channel W1. Therefore, by setting the first ventilation slot 321, cool air can not only enter the first airflow channel W1 through the first ventilation slot 321, but the air flowing within the first airflow channel W1 can also effectively expand the heat of the hard drive 10, reducing the thermal resistance and temperature of the hard drive 10. Furthermore, through the direct contact between the first airflow channel W1 and the hard drive 10, the first airflow channel W1 can fully exert its temperature equalization function, ensuring a uniform temperature difference throughout the hard drive 10. This results in the hard drive module 100 having good thermal conductivity and heat transfer efficiency, effectively improving the heat dissipation performance of the hard drive module 100. Cold air enters the first air duct W1 through the first ventilation slot 321. During the flow of air in the first air duct W1, it carries the heat generated by the hard drive 10 and becomes hot air. The hot air passes through heat dissipation devices such as the fan module in the electronic device 200 and is then discharged from the electronic device 200. The cold and hot air alternately circulate repeatedly to complete the uninterrupted heat exchange of the hard drive module 100 and ensure that the hard drive module 100 always has good heat dissipation performance.

[0093] The structure of the first ventilation slot 321 will be described in detail below through three different application scenarios.

[0094] In the first possible application scenario, the first ventilation slot 321 extends along the first direction X. With this configuration, a larger number of first ventilation slots 321 can be arranged on the top plate 32, which is beneficial to further improve the heat dissipation performance of the hard disk module 100.

[0095] In this application scenario, please refer to the relevant documentation. Figure 12 , Figure 13 and Figure 14 , Figure 12 yes Figure 2 The first ventilation slot 321 of the base 30 shown is a schematic diagram of a first structure in a first application scenario. Figure 13 yes Figure 2 The first ventilation slot 321 of the base 30 shown is a schematic diagram of a second structure in a first application scenario. Figure 14 yes Figure 2 The first ventilation slot 321 of the base 30 shown is a schematic diagram of a third structure in a first application scenario.

[0096] The first ventilation slot 321 may include a first end 322 and a second end 323, with the second end 323 being closer to the bracket 20 than the first end 322. For example, as shown... Figure 12 As shown, the length of the first end 322 in the second direction Y can be equal to the length of the second end 323 in the second direction Y. Or, as...Figure 13 and Figure 14 As shown, the length of the first end 322 in the second direction Y can be less than the length of the second end 323 in the second direction Y. With this configuration, the length of the first ventilation slot 321 in the second direction Y will vary with the extension direction of the first ventilation slot 321, thereby allowing the first ventilation slot 321 to present... Figure 13 The trumpet-shaped or Figure 14 The trapezoidal shape shown allows the second end 323 of the first ventilation slot 321 to act as a guide, directing more cool air to the top surface 11 of the hard drive 10, which helps improve the overall heat dissipation efficiency of the hard drive module 100. Alternatively, the length of the first end 322 in the second direction Y can also be greater than the length of the second end 323 in the second direction Y; this is not strictly limited.

[0097] Please refer to the following: Figure 15 and Figure 16 , Figure 15 yes Figure 2 The diagram shown is a fourth structural representation of the first ventilation slot 321 of the base 30 in a first application scenario. Figure 16 yes Figure 2 The first ventilation slot 321 of the base 30 shown is a fifth structural schematic diagram in a first application scenario.

[0098] In this application scenario, the first ventilation slot 321 may further include a first opening 324 and a second opening 325 disposed opposite to each other in the Z direction. The first opening 324 is disposed on the surface of the top plate 32 facing the ventilation cavity 34, and the second opening 325 is disposed on the surface of the top plate 32 facing away from the ventilation cavity 34. For example, as Figure 15 As shown, the length of the first opening 324 in the first direction X can be equal to the length of the second opening 325 in the first direction X. Or, as... Figure 16 As shown, the length of the first opening 324 in the first direction X can be greater than the length of the second opening 325 in the first direction X. That is, in the direction from the first opening 324 to the second opening 325, the length of the first ventilation slot 321 in the second direction Y will vary with the extension direction of the first ventilation slot 321. With this configuration, the first ventilation slot 321 has a larger contact area with the cold air in the ventilation cavity 34, which can guide more cold air into the first ventilation slot 321, which is beneficial to further improve the heat dissipation performance of the hard drive module 100. Alternatively, the length of the first opening 324 in the first direction X can be less than the length of the second opening 325 in the first direction X, and there is no strict limitation on this.

[0099] Please see Figure 17 , Figure 17 yes Figure 2A structure diagram of the first vent groove 321 of the base 30 in one of the second application scenarios is shown.

[0100] In the second possible application scenario, the same content as the first application scenario will not be repeated, and the difference from the first application scenario is that, as shown in Figure 17 As shown, the extension direction of the first vent groove 321 is obliquely arranged with the first direction X. Under this arrangement, the first vent groove 321 can have a longer extension size. On the one hand, the longer extension size of the first vent groove 321 can layout a larger volume of the first vent groove 321 in a limited space, meet the depth requirement inside the space of the hard disk module 100, and can flow a larger volume of cold air to the first vent groove 321 at a time under the same volume of the vent cavity 34, so that more cold air can be blown to the top surface 11 of the hard disk 10 under a single heat exchange cycle. On the other hand, the obliquely arranged first vent groove 321 can reduce the space size of the top plate 32 occupied in the first direction X, and the space of the top plate 32 released due to the oblique placement can correspondingly layout more first vent grooves 321, thereby maximizing the number of first vent grooves 321 and effectively improving the heat dissipation performance of the hard disk module 100.

[0101] Please refer to Figure 18 , Figure 18 is Figure 2 A structure diagram of the first vent groove 321 of the base 30 in one of the third application scenarios is shown.

[0102] In the third possible application scenario, the same content as the first application scenario will not be repeated, and the difference from the first application scenario is that, as shown in Figure 18 As shown, the first vent groove 321 extends along the second direction Y. Under this arrangement, the first vent groove 321 can have a longer extension size, which is conducive to contacting more cold air.

[0103] Please refer to Figure 10 and Figure 11 In the embodiments of the present application, the bottom plate 33 is connected to the other side of the end plate 31, and the bottom plate 33 can have a plurality of second vent grooves 331 arranged at intervals. Each second vent groove 331 penetrates the bottom plate 33 along the third direction Z. Each second vent groove 331 communicates the vent cavity 34 and the external environment, so that the air entering the vent cavity 34 flows to the bottom surface 12 of the hard disk 10 after passing through the plurality of second vent grooves 331.

[0104] Optionally, the second vent groove 331 can be located only on the bottom plate 33, or, as shown in Figure 11 The second vent groove 331 can be located on the bottom plate 33 and the end plate 31, that is, the second vent groove 331 can extend from the bottom plate 33 to the end plate 31.

[0105] It should be noted that the slot shape of each second vent groove 331, the size of each second vent groove 331, the setting position of each second vent groove 331, the spacing between adjacent two second vent grooves 331, and the actual number of the plurality of second vent grooves 331 can be selected according to the actual application scene, and no strict limitation is made.

[0106] It can be understood that when the hard disk module 100 is installed in the case 210 of the electronic device 200, the case 210 and the bottom surface 12 of the hard disk 10 form a second air duct W2. The second air duct W2 is in communication with the second vent groove 331, so that the cold air can flow from the vent cavity 34 of the base 30 to the second air duct W2. Therefore, by providing the second vent groove 331, not only can the cold air enter the second air duct W2 through the second vent groove 331, but also the heat of the hard disk 10 can be effectively spread by the air flowing in the second air duct W2, reducing the thermal resistance and temperature of the hard disk 10. The second air duct W2 can also directly contact the hard disk 10 through the second air duct W2, so that the second air duct W2 can fully play its role in uniform temperature, so that the temperature difference of each position of the hard disk 10 is uniform, and the hard disk module 100 as a whole has good heat conduction temperature difference and heat transfer efficiency, effectively improving the heat dissipation performance of the hard disk module 100. The cold air enters the second air duct W2 through the second vent groove 331, and becomes hot air by carrying the heat generated by the hard disk 10 in the flow of the second air duct W2. The hot air is discharged from the electronic device 200 after passing through the heat dissipation device such as the fan module in the electronic device 200. The cold and hot air alternately circulate and repeat, so as to complete the uninterrupted heat exchange of the hard disk module 100, and ensure that the hard disk module 100 always has good heat dissipation performance.

[0107] The structure of the second vent groove 331 will be described in detail below through three different application scenarios.

[0108] In a first possible application scenario, the second vent groove 331 extends along the first direction X. Under this setting, a larger number of second vent grooves 331 can be arranged on the bottom plate 33, which is conducive to further improving the heat dissipation performance of the hard disk module 100.

[0109] In this application scenario, please refer to Figure 19 , Figure 20 and Figure 21 , Figure 19 is a first structure diagram of the second vent groove 331 of the base 30 in the first application scenario shown in Figure 2 , Figure 20 is a second structure diagram of the second vent groove 331 of the base 30 in the first application scenario shown in Figure 2 , Figure 21 is a third structure diagram of the second vent groove 331 of the base 30 in the first application scenario shown in Figure 2The second vent groove 331 of the base 30 is shown in a third structural schematic view in the first application scenario.

[0110] The second vent groove 331 can include a third end 332 and a fourth end 333, the fourth end 333 being closer to the bracket 20 than the third end 332. Exemplarily, as shown in Figure 19 The length of the third end 332 in the second direction Y can be equal to the length of the fourth end 333 in the second direction Y. Alternatively, as shown in Figure 20 and Figure 21 The length of the third end 332 in the second direction Y can be less than the length of the fourth end 333 in the second direction Y. In this case, the length of the second vent groove 331 in the second direction Y varies with the extension direction of the second vent groove 331, so that the second vent groove 331 can present Figure 20 a trumpet shape as shown in Figure 21 a trapezoidal shape as shown, so that the fourth end 333 of the second vent groove 331 plays a role of guiding flow, and more cold air can be guided to the bottom surface 12 of the hard disk 10, which is conducive to improving the overall heat dissipation efficiency of the hard disk module 100. Alternatively, the length of the third end 332 in the second direction Y can be greater than the length of the fourth end 333 in the second direction Y, which is not strictly limited.

[0111] Please refer to Figure 22 and Figure 23 , Figure 22 is Figure 2 a fourth structural schematic view of the second vent groove 331 of the base 30 in the first application scenario, Figure 23 is Figure 2 a fifth structural schematic view of the second vent groove 331 of the base 30 in the first application scenario.

[0112] In this application scenario, the second vent groove 331 can further include a third opening 334 and a fourth opening 335 arranged oppositely in the third direction Z, the third opening 334 being arranged on the surface of the bottom plate 33 facing the vent cavity 34, and the fourth opening 335 being arranged on the surface of the bottom plate 33 facing away from the vent cavity 34. Exemplarily, as shown in Figure 22 The length of the third opening 334 in the first direction X can be equal to the length of the fourth opening 335 in the first direction X. Alternatively, as shown in Figure 23As shown, the length of the third opening 334 in the first direction X can be greater than the length of the fourth opening 335 in the first direction X. That is, in the direction from the third opening 334 to the fourth opening 335, the length of the second air vent 331 in the second direction Y changes with the extension direction of the second air vent 331. In this arrangement, the second air vent 331 has a larger contact area with the cold air in the air cavity 34, and more cold air can be introduced into the second air vent 331, which is conducive to further improving the heat dissipation performance of the hard disk module 100. Alternatively, the length of the third opening 334 in the first direction X can be less than the length of the fourth opening 335 in the first direction X, which is not strictly limited.

[0113] Referring to Figure 24 , Figure 24 is Figure 2 a structural schematic view of the second air vent 331 of the base 30 shown in FIG. 1 in a third application scenario.

[0114] In the third possible application scenario, the same content as the first application scenario will not be repeated, and the difference from the first application scenario is that, as shown in Figure 24 , the extension direction of the second air vent 331 is arranged obliquely to the first direction X. In this arrangement, the second air vent 331 has a longer extension size. On the one hand, the longer extension size of the second air vent 331 can layout a larger volume of the second air vent 331 in a limited space, meet the depth requirement of the space inside the hard disk module 100, and in the same volume of the air cavity 34, a larger volume of cold air can be introduced into the second air vent 331 at a time, so that more cold air can be blown to the bottom surface 12 of the hard disk 10 in a single heat exchange cycle. On the other hand, the obliquely arranged second air vent 331 can reduce the space size of the bottom plate 33 occupied in the first direction X, and the space of the bottom plate 33 released by the oblique placement can correspondingly layout more second air vents 331, thereby maximizing the number of second air vents 331 and effectively improving the heat dissipation performance of the hard disk module 100.

[0115] Referring to Figure 25 , Figure 25 is Figure 2 a structural schematic view of the second air vent 331 of the base 30 shown in FIG. 1 in a third application scenario.

[0116] In the third possible application scenario, the same content as the first application scenario will not be repeated, and the difference from the first application scenario is that, as shown in Figure 25 , the second air vent 331 extends along the second direction Y. In this arrangement, the second air vent 331 has a longer extension size, which is conducive to contacting more cold air.

[0118] In the embodiment of the present application, the shielding shell 40 covers the periphery of the base 30, and the shielding shell 40 is located between the base 30 and the support 20. The shielding shell 40 can be made of metal material or non-metal material with a conductive plating layer on the surface of the non-metal material, so that the hard disk module 100 has good electromagnetic shielding performance.

[0119] Specifically, the base 30 can further include an outer shell 35, which is arranged on the side of the top plate 32 and the bottom plate 33 away from the end plate 31, and is fixedly connected with the top plate 32, the bottom plate 33 and the end plate 31. The shielding shell 40 covers the periphery of the top plate 32, the bottom plate 33 and the end plate 31, and is fixedly connected with the outer shell 35. The shielding shell 40 is provided with a plurality of heat dissipation holes 41, which are distributed on the shielding shell 40 at intervals, so as to dissipate heat for the hard disk 10.

[0120] In a possible implementation manner, as shown in Figure 24 and Figure 25 , the outer shell 35 can be provided with a plurality of first clamping bodies 351 and a plurality of second clamping bodies 352. The plurality of first clamping bodies 351 are arranged at intervals on the side of the outer shell 35 close to the top plate 32, and are arranged at intervals with the plurality of first ventilation grooves 321. The first clamping body 351 is used for clamping the outer shell 35 to realize the clamping connection of the base 30 and the shielding shell 40. The plurality of second clamping bodies 352 are arranged at intervals on the side of the outer shell 35 close to the bottom plate 33, and are arranged at intervals with the plurality of second ventilation grooves 331. The second clamping body 352 is used for clamping the outer shell 35 to realize the clamping connection of the base 30 and the shielding shell 40.

The wrench 50 is rotatably connected with the base 30, and can rotate relative to the base 30, so that the hard disk module 100 can be in a locked state or an unlocked state. Exemplarily, the dial key 60 can be made of plastic, for example, the dial key 60 can be a plastic piece made of polycarbonate, and a film is plated on the surface of the plastic to make it a translucent plastic piece.

[0122] Please continue to refer to Figure 2 and Figure 3In the embodiments of the present application, the light guide 70 is fixed to the bracket 20, and the light guide 70 extends from the bracket 20 to the knob 60.
