These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] As described in the background section, the cooling medium in related technologies contains a large amount of impurities, resulting in a significant amount of impurities remaining inside the chassis.

[0048] To address the aforementioned technical problems, embodiments of this application provide a placeholder component and a computing device. By setting a body and a filter element, the body includes a protrusion and a body portion connected together. The protrusion is embedded in the inner cavity of an unused slot to prevent impurities from accumulating in the unused slot. In addition, the body portion is located outside the unused slot and has a through hole penetrating the body. The filter element is embedded in the inner cavity of the through hole and filters the cooling medium flowing through the filter element to reduce impurities in the cooling medium.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0050] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0051] As described in the background section, there is a problem in the related technology where the sealing effect between the fake memory stick and the memory card slot is poor, resulting in impurities accumulating in the inner cavity of the memory card slot.

[0052] To address the aforementioned technical problems, this application provides a sealing assembly. The protrusion of the sealing assembly can be inserted into the inner cavity of an unused card slot from its open end. The first sealing part of the sealing assembly can abut against the end face of the open end of the unused card slot to achieve a seal between the main body and the end face of the open end of the unused card slot, thereby preventing impurities from accumulating in the inner cavity of the unused card slot.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0054] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] Figure 1 This is a partial top view of a computing device provided in an embodiment of this application. Figure 2 A partial front view of a computing device provided in an embodiment of this application. (Reference) Figure 1 and Figure 2 The computing device provided in this application embodiment may include a chassis 2000 having an inner cavity 4300, and a circuit board 3000 may be provided in the inner cavity of the chassis 2000.

[0056] The chassis 2000 may have a top wall and a bottom wall on both sides in its height direction. The circuit board 3000 may be parallel to the bottom wall of the chassis 2000, and the circuit board 3000 may be as follows: Figure 2 The circuit board 3000 is connected to the bottom wall of the chassis 2000, or it is suspended above the bottom wall of the chassis 2000.

[0057] Continue to refer to Figure 1 and Figure 2 The circuit board 3000 may have two opposing surfaces along the height of the chassis 2000. At least one surface of the circuit board 3000 may be provided with computing chips such as CPU (central processing unit), GPU (graphics processing unit), or ASIC (application specific integrated circuit).

[0058] In addition, to enable data storage in the computing device, at least one circuit board 3000 may have a memory module on its surface. (Reference) Figure 2The circuit board 3000 may also have a memory card slot on its surface, and the memory card slot may have an open end on the side of the board surface away from the circuit board 3000. The memory module can be inserted into the cavity 4300 of the memory card slot through the open end, and can be electrically connected to computing chips such as the CPU through the memory card slot.

[0059] The circuit board 3000 can also be equipped with multiple expansion card slots, which can be used to expand at least one of the following: GPU (Graphics Processing Unit) card, network card, video capture card, HBA (Host Bus Adapter) card, RAID (Redundant Arrays of Independent Disks) card, and PCIe (Peripheral Component Interconnect express) card. It can also support the expansion of various adapter cards.

[0060] Memory card slots and expansion card slots can be collectively referred to as card slots, and memory modules, GPU cards, network cards, video capture cards, HBA cards, RAID cards, and PCIe cards can be collectively referred to as function cards 3100. Each card slot's internal cavity 4300 may be equipped with an electrical connector, allowing the function card 3100 to engage with the connector and connect to other electrical components. Furthermore, the chassis 2000 may have multiple card slots within its internal cavity. When all card slots are fully loaded, one electrically connected function card 3100 can be inserted into each slot's internal cavity. At this time, all card slots can be referred to as used card slots 4100. When all card slots are not fully loaded, at least one electrically connected function card 3100 is not inserted into its internal cavity. At this time, the memory card slot without an inserted memory module can be referred to as an idle card slot 4200.

[0061] Understandably, computing devices can dissipate heat through liquid, gaseous, or two-phase cooling media. Since the cooling media contains impurities, to avoid contaminating the connector in the inner cavity 4300 of the unused slot 4200, the sealing assembly 1000 provided in this embodiment can be inserted into the unused slot 4200 during operation to seal the inner cavity 4300 of the unused slot 4200, thus preventing liquid or gaseous cooling media carrying impurities from entering the inner cavity 4300 of the unused slot 4200.

[0062] First, it should be noted that, for ease of description, the embodiments of this application introduce a first direction X, a second direction Y, and a third direction Z. These three directions are perpendicular to each other.

[0063] Figure 3 This is a schematic diagram showing the sealing assembly 1000 separated from the idle card slot 4200 according to an embodiment of this application. Figure 4 for Figure 3 A longitudinal sectional view of the sealing assembly 1000 in one direction is shown. (Reference) Figure 3 and Figure 4 The sealing assembly 1000 provided in this application embodiment may include a body 100, which may include a body portion 110 and two protrusions 120. The body portion 110 may have a top end and a bottom end oppositely disposed in a third direction Z, and the two protrusions 120 may be disposed at the bottom end of the body portion 110. The two protrusions 120 may be spaced apart along a first direction X, that is, the two protrusions 120 have a certain distance between them in the first direction X. Figure 3 and Figure 4 In this structure, two protrusions 120 are respectively connected to the bottom end of the main body 110 at both ends along the first direction X. Furthermore, the two protrusions 120 and the main body 110 located between the two protrusions 120 enclose a receiving space 130. This receiving space 130 is through-hole in the second direction Y. That is, the receiving space 130 communicates with the outside at both ends in the second direction Y; in other words, the receiving space 130 is open at both ends in the second direction Y. In addition, the end of the receiving space 130 away from the main body 110 also communicates with the outside. The receiving space 130 is open at the end away from the main body 110.

[0064] Figure 5 for Figure 3 A longitudinal sectional view from another direction is shown of the sealing assembly 1000 when it mates with the idle slot 4200. (See reference) Figure 3 and Figure 5 The unused card slot 4200 may have a first engaging portion and a second engaging portion disposed opposite to each other at both ends in the first direction X. Both the first engaging portion and the second engaging portion are higher than the end face 4400 of the open end of the unused card slot 4200, and both the first engaging portion and the second engaging portion are provided with a through groove extending in the third direction Z, and the through groove communicates with the inner cavity 4300 of the unused card slot 4200.

[0065] When the sealing assembly 1000 is assembled with the unused slot 4200, the body portion 110 engages with the first engaging portion and the second engaging portion at both ends in the first direction X, respectively. The two protrusions 120 are inserted into the inner cavity 4300 of the unused slot 4200 through the through grooves of the first and second engaging portions, respectively, so that the accommodating space communicates with the inner cavity 4300 of the unused slot 4200 at the end furthest from the body portion 110. Optionally, the unused slot 4200 may have two opposing inner wall surfaces in the first direction X, and these two inner wall surfaces may be provided with latches. The two protrusions 120 may engage with the latches on these two inner wall surfaces, respectively.

[0066] refer to Figure 5After the sealing assembly 1000 is assembled with the idle slot 4200, a gap exists between the bottom end of the body portion 110 and the end face 4400 of the opening end of the idle slot 4200. Impurities in the inner cavity 4300 of the chassis 2000 may enter the receiving space 130 from both ends of the aforementioned receiving space 130 in the second direction Y through this gap, and enter the inner cavity 4300 of the idle slot 4200 through the end of the receiving space 130 away from the body portion 110. In order to seal this gap, the sealing assembly 1000 provided in this application embodiment may include a sealing member 200, which may include a first sealing portion 210 connected to the bottom end of the body portion 110. Exemplarily, an adhesive layer 300 may be provided between the first sealing portion 210 and the body portion 110, and the first sealing portion 210 and the body portion 110 may be connected through the adhesive layer 300.

[0067] Furthermore, the first sealing portion 210 can seal both ends of the aforementioned receiving space 130 in the second direction Y. In the second direction Y, the width of the first sealing portion 210 can be greater than the width of the protrusion 120. Further, the width of the first sealing portion 210 can be greater than the width of the inner cavity 4300 of the unused slot 4200, so that after the sealing assembly 1000 is assembled with the unused slot 4200, the portion of the first sealing portion 210 extending beyond the protrusion 120 can be pressed against the end face 4400 of the open end of the unused slot 4200 by the pressure of the body portion 110 or the tension of the protrusion 120, thereby achieving a seal between the body portion 110 and the end face 4400 of the open end of the unused slot 4200. The sealing member 200 may be made of an elastic rubber material.

[0068] In addition, to further improve the sealing effect, the width of the first sealing part 210 may be greater than the width of the end face 4400 of the open end of the unused card slot 4200.

[0069] Optionally, in order for the protrusion 120 to be embedded in the inner cavity 4300 of the unused slot 4200, the thickness of the first sealing part 210 in the third direction Z may be less than the thickness of the protrusion 120.

[0070] The following describes the possible implementation of the first sealing part 210 covering the receiving space 130 at both ends of the second direction Y.

[0071] refer to Figures 6-11 In one possible implementation of the first sealing portion 210, at least a portion of the first sealing portion 210 is located in the receiving space 130, and at least a portion of the first sealing portion 210 can abut against the two protrusions 120 at both ends along the first direction X. That is, the first sealing portion 210 seals both ends of the receiving space 130 in the second direction Y by being embedded in the receiving space 130.

[0072] Figure 6 A transverse sectional view of the first sealing assembly 1000 provided in the embodiments of this application. Figure 7 This is a cross-sectional view of the second sealing assembly 1000 provided in the embodiments of this application. Figure 8 for Figure 3 A cross-sectional view of the sealing assembly 1000 is shown. (Reference) Figures 6-8 For example, the first sealing portion 210 may pass through the receiving space 130 along the second direction Y, and both ends of the first sealing portion 210 in the second direction Y may extend out of the receiving space 130. This is so that the width of the first sealing portion 210 in the second direction Y may be greater than the width of the receiving space 130; that is, the width of the first sealing portion 210 may be greater than the width of the body portion 110 between the two protrusions 120; in other words, the width of the first sealing portion 210 may be greater than the width of the protrusions 120.

[0073] Figure 9 A transverse sectional view of the fourth sealing assembly 1000 provided in the embodiments of this application, with reference to... Figure 9 In another exemplary embodiment, the first sealing portion 210 may include two portions, which may be spaced apart along the second direction Y. One portion may pass through one end of the receiving space 130 in the second direction Y, and this portion may be located within the receiving space 130 at one end in the second direction Y, while the other end of this portion may be located outside the receiving space 130. The other portion of the first sealing portion 210 may pass through the receiving space 130 at the other end in the second direction Y, and this portion may be located within the receiving space 130 at one end in the second direction Y, while the other end of this portion may be located outside the receiving space 130.

[0074] Figure 10 A transverse sectional view of the fifth sealing assembly 1000 provided in an embodiment of this application. (See reference...) Figure 10 In another possible implementation, the first sealing portion 210 surrounds the receiving space 130 on both sides of the second direction Y. Specifically, the first sealing portion 210 may include two portions spaced apart along the second direction Y, and these two portions may be respectively disposed on both sides of the receiving space 130 in the second direction Y, so as to respectively cover the two ends of the receiving space 130 in the second direction Y.

[0075] It should be noted that regardless of the sealing method used by the first sealing portion 210, the width of the body portion 110 in the second direction Y may not be less than the width of the protrusion 120. For example, the width of the body portion 110 in the second direction Y may be as follows: Figure 6 The width of the body portion 110 is equal to that of the protrusion 120 and may be smaller than that of the first sealing portion 210; or, in the second direction Y, the width of the body portion 110 may be as shown. Figure 7The width of the body portion 110 is equal to, and may be larger than, the first sealing portion 210, to improve the occupancy capacity of the sealing assembly 1000, thereby reducing the amount of cooling medium used in the computing device; or, in the second direction Y, the width of the body portion 110 may be as shown in the figure. Figures 8-10 The portion shown is smaller than the first sealing portion 210 to improve the sealing effect.

[0076] Figure 11 This is a longitudinal sectional view from another direction when the sixth sealing assembly 1000 provided in this embodiment of the application is engaged with an unused slot 4200. (See reference...) Figure 11 To further improve the sealing effect, the seal 200 may optionally include a second sealing portion 220. This second sealing portion 220 may be connected to the end of the first sealing portion 210 away from the body portion 110, and the second sealing portion 220 may be disposed opposite to the receiving space 130. In the first direction X, the length of the second sealing portion 220 may be less than the length of the body portion 110 between the two protrusions 120, so that when the sealing assembly 1000 is assembled with the idle slot 4200, the second sealing portion 220 can be... Figure 11 The second sealing portion 220 is embedded in the inner cavity 4300 of the unused slot 4200. Furthermore, in the second direction Y, the width of the second sealing portion 220 may not be less than the width of the protrusion 120. Further, the width of the second sealing portion 220 may not be less than the width of the unused slot 4200.

[0077] Furthermore, the second sealing portion 220 can be rectangular in shape in the YZ section. Alternatively, refer to... Figure 11 The shape of the second sealing part 220 in the YZ section can be an inverted trapezoid. In this case, the cross-section of the second sealing part 220 can tend to decrease in the direction away from the first sealing part 210, so that when the sealing assembly 1000 is assembled with the idle slot 4200, the end of the second sealing part 220 away from the first sealing part 210 can be embedded in the inner cavity 4300 of the idle slot 4200, and the end of the second sealing part 220 close to the first sealing part 210 can be interference-fitted with the inner cavity 4300 of the idle slot 4200 to achieve a further sealing effect.

[0078] Figure 12 A longitudinal sectional view from another direction of the seventh sealing assembly 1000 provided in this application embodiment when it mates with an unused slot 4200. (See reference) Figure 12 Optionally, the seal 200 may further include a third sealing portion 230. The third sealing portion 230 may be connected to both ends of the first sealing portion 210 in the second direction Y, and the third sealing portion 230 may be bent relative to the first sealing portion 210 in a direction away from the body portion 110.

[0079] Specifically, after the sealing assembly 1000 is assembled with the idle slot 4200, the third sealing part 230 may be located outside the end face 4400 of the open end of the idle slot 4200, so as to further prevent the cooling medium from entering the inner cavity 4300 of the idle slot 4200.

[0080] Furthermore, the outer surface of the third sealing part 230 is a slope, and the end of the outer surface away from the body part 110 is closer to the centerline of the first sealing part 210 than the end of the outer surface closer to the body part 110, so as to reduce the pressure of the cooling medium on the third sealing part 230.

[0081] Furthermore, the inner surface of the third sealing part 230 can be fitted to the side surface of the open end of the unused slot 4200, so as to provide support for the third sealing part 230 by utilizing the open end of the unused slot 4200, and also to improve the sealing effect.

[0082] Of course, the seal 200 may also include a second sealing part 220 and a third sealing part 230 to further improve the sealing effect.

[0083] refer to Figure 1 The chassis 2000 may have an inlet 2100 and an outlet 2200 on its walls, both of which can communicate with the internal cavity of the chassis 2000. To reduce the temperature of the electrical components inside the server, the server may employ cooling methods such as air cooling, liquid cooling, or LAAC (Liquid Assisted Air Cooling).

[0084] For example, when the server is air-cooled, Figure 1 The arrows in the image indicate the flow direction of cooling media such as air. (Refer to...) Figure 1 The fan can guide the cooling medium from the outside of the chassis 2000 into the inner cavity of the chassis 2000 through the inlet 2100, blow it onto the electrical components in the inner cavity of the chassis 2000, and flow out of the inner cavity of the chassis 2000 from the outlet 2200.

[0085] For example, when the server uses liquid cooling, the internal cavity of the chassis 2000 can contain a certain level of cooling medium such as fluorinated liquid. Figure 1The arrows indicate the flow direction of the cooling medium. Electrical components can be immersed in the cooling medium. Specifically, the top of the electrical component can be above the surface of the cooling medium, so that part of the component is above the surface and another part is below; alternatively, the top of the component can be below the surface of the cooling medium, so that the component is completely immersed. A cooling device can be installed on the outside of the chassis 2000. This cooling device can be connected to the inlet 2100 and outlet 2200 of the chassis 2000 via pipes to form a loop. The pipes can be equipped with a pump, which can be used to circulate the cooling medium between the interior of the chassis 2000 and the cooling device, thereby cooling the electrical components.

[0086] Understandably, regardless of the cooling method used, a cooling medium is required, and the cooling medium has a certain flow direction within the internal cavity of the 2000 chassis. Figure 13 A longitudinal sectional view in one direction of another sealing assembly provided in an embodiment of this application. (Refer to...) Figure 13 In order to reduce impurities in the cooling medium or the inner cavity of the chassis 2000, the top of the main body may be located outside the unused slot 4200, and a filter element 400 may be provided on the top of the main body, which can filter the cooling medium flowing through the filter element 400.

[0087] Optionally, Figure 1 In this embodiment, the cooling medium inside the chassis 2000 can flow along the length of the chassis 2000, and the length of the unused slot 4200 can also be arranged along the length of the chassis 2000. In this embodiment, after the sealing assembly is assembled with the unused slot, the first direction X can be arranged along the length of the chassis 2000, and the filter element 400 can be arranged as follows: Figure 13 As shown, it is inserted through the top of the main body along the first direction X.

[0088] Optionally, the size of the impurities filtered out by the filter element 400 may gradually decrease along the flow direction of the cooling medium. Exemplarily, the filter element 400 may include a housing 410, a partition plate 420, and at least two filter sections. The housing 410 may have an inlet, an outlet, and an internal cavity communicating with the inlet and outlet. The partition plate 420 may be disposed within the internal cavity of the housing 410 and may divide the internal cavity of the housing 410 into at least two chambers. Additionally, the partition plate 420 may have a through-hole extending through the partition plate 420 so that the cooling medium can flow from one chamber to another through the through-hole. Furthermore, at least two filter sections may be disposed correspondingly in at least two chambers, and the size of the impurities filtered out by the at least two filter sections gradually decreases along the flow direction of the cooling medium.

[0089] refer to Figure 13For example, there may be two isolation plates 420, which are spaced apart in the inner cavity of the outer casing 410 along the flow direction of the cooling medium, dividing the inner cavity of the outer casing 410 into three chambers. These three chambers can respectively accommodate the first filter section 430, the second filter section 440, and the third filter section 450. The cooling medium can pass through the first filter section 430, the second filter section 440, and the third filter section 450 in sequence, and the size of the impurities that can be filtered out by the first filter section 430, the second filter section 440, and the third filter section 450 gradually decreases. Among them, the first filter section 430 can be a large particulate filter material, the second filter section 440 can be a small particulate filter material such as activated carbon, and the third filter section 450 can be a filter material with small pores such as fiber cotton.

[0090] Figure 14 A longitudinal sectional view from another direction showing the two sealing components provided in this application's embodiments engaging with two unused slots. (See reference...) Figure 14 Optionally, when there are multiple unused card slots 4200, and the multiple unused card slots 4200 are spaced apart along the width direction of the chassis 2000, there can be multiple sealing components 1000. The multiple sealing components 1000 can be spliced ​​together, and the number of sealing components 1000 can be the same as the number of unused card slots 4200. The protrusion of each sealing component 1000 can be embedded in the inner cavity 4300 of an unused card slot 4200.

[0091] In this embodiment, after the sealing assembly is assembled with the unused slots, the second direction Y can be arranged along the width direction of the chassis 2000. The main body can have opposing first and second sidewalls in the second direction Y. The first sidewall can be provided with a first mating block 510, and the second sidewall can be provided with a second mating block 520. When all adjacent unused slots 4200 are unused, a suitable number of sealing assemblies 1000 can be assembled together by the first mating block 510 and the second mating block 520, and inserted together into the adjacent unused slots 4200 to reduce the workload of the operator.

[0092] The first mating block 510 and the second mating block 520 can be mated using methods such as convex-concave mating, snap-fit ​​connection, screw and nut mating, and magnetic mating. When the first mating block 510 and the second mating block 520 are in convex-concave mating, the first mating block 510 can have a protrusion, and the second mating block 520 can have a groove, with the protrusion embedded in the inner cavity of the groove; or, the first mating block 510 can have a groove, and the second mating block 520 can have a protrusion, with the protrusion embedded in the inner cavity of the groove.

[0093] It should be noted that when the chassis 2000 uses immersion liquid cooling, a certain level of cooling medium can be deposited in the internal cavity of the chassis 2000. Understandably, with the cooling medium level remaining constant, the larger the total volume of the electrical components within the chassis 2000's internal cavity, the smaller the amount of cooling medium required. To reduce the amount of cooling medium used and improve liquid cooling efficiency, the volume of the spacer component 1000 can optionally be as large as possible.

[0094] refer to Figure 2 Optionally, the height of the placeholder component 1000 may be greater than the height of the function card 3100, so as to increase the volume of the placeholder component 1000 and thus facilitate the reduction of the amount of cooling medium used.

[0095] refer to Figure 5 Optionally, in the second direction Y, the width of the body portion 110 may be greater than the width of the protrusion 120. Further, the width of the body portion 110 may be greater than the width of the inner cavity of the unused slot 4200. Further, the width of the body portion 110 may be greater than the width of the end face 4400 of the opening end of the unused slot 4200. This is to increase the volume of the occupant assembly 1000, thereby facilitating a reduction in the amount of cooling medium used. Wherein, to avoid interference between two adjacent occupant assemblies 1000, the width of the body portion 110 may be less than or equal to the width between the center lines of two adjacent unused slots 4200.

[0096] Figure 15 This is a longitudinal sectional view from another direction when the eighth placeholder component provided in this application is assembled with an idle card slot. (See reference...) Figure 15 Optionally, the placeholder component 1000 provided in this embodiment may further include an attachment 600, which is detachably disposed on the main body 110. When the internal space of the chassis 2000 is large, the volume of the placeholder component 1000 can be increased by increasing the number of attachments 600. When the internal space of the chassis 2000 is small, the number of attachments 600 can be reduced to accommodate the internal space of the chassis 2000. The attachment 600 may be disposed on one or both sides of the main body 110 along the first direction X and / or the second direction Y and / or the third direction Z.

[0097] It should be noted that, Figure 15 The example shown illustrates the connection between the main body 110 and the attachment 600 via a first mating block 510 and a second mating block 520. Of course, the main body 110 and the attachment 600 can also be detachably connected via methods such as snap-fit ​​connection, screw and nut engagement, or magnetic engagement. Furthermore, if space permits within the chassis 2000's interior, another attachment 600 can be installed on the outside of one attachment 600 to maximize the use of interior space within the chassis 2000.
