Abstract
Description
Technical Field
[0001] This application relates to the field of electronic device technology, and in particular to an expansion card module and electronic device. Background Technology

Detailed Implementation
[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0047] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.
[0048] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:
[0049] Example 1
[0050] Reference Appendix Figure 1 The expansion card module provided in this application includes a frame 1 and an adjustment bracket 2. The frame 1 is adapted to the function card slot of an electronic device and is movably disposed at the function card slot. The adjustment bracket 2 is movably disposed within the frame 1 and has a first target state and a second target state relative to the frame 1. In the first target state, the adjustment bracket 2 forms a first target angle with the insertion direction of the function card slot to achieve a first degree of penetration in the airflow channel of the function card slot. In the second target state, the adjustment bracket 2 forms a second target angle with the insertion direction of the function card slot to adjust the airflow channel of the function card slot to a second degree of penetration, wherein the second degree of penetration is different from the first degree of penetration.
[0051] Understandably, in order to address the problem of increased fan power consumption and wasted energy and costs caused by some slots on existing servers where no expansion cards are inserted, the expansion card module provided in this embodiment can adjust the airflow channel of at least the corresponding function card slot by switching the state of the adjustment bracket 2 inside the frame 1. This adjusts the airflow of the function card slot with inserted cards. For electronic devices with multi-function card slots, the expansion card module can increase or adjust the air outlet resistance of the function card slot without inserted function cards 6 as needed, forcing the cooling fluid blown out of the electronic device to pass through the function card slot with inserted function cards 6. This balances the air outlet resistance and airflow of each function card slot, improves heat dissipation efficiency, and reduces the power consumption of the fan inside the electronic device.
[0052] In this embodiment, the expansion card module can replace the function card 6 to occupy or block the function card slots of electronic devices. For example, it can be used for, but is not limited to, PCIE expansion cards (PCIE, Peripheral Component Interconnect Express), OCP network cards (OCP, Open Compute Project), AGP (Accelerated Graphics Port), etc. Furthermore, when an electronic device has multiple function card slots and some slots are occupied by the actual function card 6, the expansion card module provided in this embodiment can occupy or block the unoccupied function card slots to balance the airflow resistance and air volume of all function card slots and improve heat dissipation efficiency.
[0053] The expansion card module provided in this embodiment can be used or sold in conjunction with electronic devices such as server chassis and desktop chassis. Such electronic devices have multiple function card slots at the front or rear. The function card slots provide a medium for electrical connection between the expansion card or function card and the motherboard of the electronic device. They allow the expansion card or function card to be inserted into the slot to achieve connection with the motherboard. This setting is easily understood by those skilled in the art and will not be described in detail here. The types of expansion cards or function cards mentioned above are referred to the above description and will not be described in detail here.
[0054] The frame 1 is a rigid structure. It can be a frame structure that can insert a function card slot, or it can be a frame structure that can cover the opening of the function card slot. The shape and size of the frame 1 can be adapted to the function card slot on the electronic device. For example, it can be a rectangular frame, a rectangular hollow frame, a slot-shaped frame with an opening on one side, etc. It can provide conditions for the installation of the adjustment bracket 2. The thickness of the frame 1 can correspond to the height of one function card slot or the size of multiple function card slots at the same time, so as to achieve flexible application in different usage scenarios. For example, when there is only one function card slot or multiple individual function card slots in different positions need to be occupied or covered by the expansion card module. Therefore, an expansion card module whose thickness dimension of frame 1 corresponds to the height of one function card slot can be used. Correspondingly, when multiple adjacent function card slots need to be occupied or blocked by expansion card modules at the same time, an expansion card module whose thickness dimension of frame 1 corresponds to the height of multiple function card slots can be used. Of course, in this embodiment, dedicated expansion card modules can also be set for different function card slots. For example, for a server, its front-end function card slot can be for OCP network cards, and its rear-end function card slot can be for PCIe cards. Thus, the thickness dimension of frame 1 can be for PCIe cards or for OCP cards. The frame 1 can be made of metal, plastic, etc.; the way the frame 1 and the function card slot are connected can be, but is not limited to, insertion, snap-fit, hooking, etc. It is understood that the movement of the frame 1 and the function card slot is for the installation and removal process. Once the expansion card module and the function card slot are installed, the frame 1 has no relative movement to the function card slot. Accordingly, the frame 1 has at least one surface that can cover the opening of the function card slot to ensure the consistency and integrity of the external attachment of the electronic device. The expansion card module, or the frame 1, can be kept in the installed state within the function card slot by snap-fit, bolt locking, etc., for example: see attached... Figure 1 and attached Figure 9 When the expansion card module is applied to the back or rear of an electronic device without affecting its aesthetic appearance, a connecting plate 4 can be provided on the side of the frame 1 facing away from the function card slot. The connecting plate 4 has a bent plate 41 along one side of the thickness of the frame 1, extending along the insertion direction of the function card slot. The bent plate 41 has a connecting through hole for bolt locking between the connecting plate 4 and the frame 1. At least one end of the connecting plate 4 in the length direction has an opening plate 42 extending in the opposite direction to the insertion direction of the function card slot, allowing the opening plate 42 to be bolted onto the electronic device housing 7 around the function card slot. This configuration is easily understood by those skilled in the art and will not be elaborated upon here. For example, refer to the attached... Figure 12When the application of the expansion card module to the front of an electronic device may affect the aesthetic appearance of the electronic device, a buckle 5 can be set on the outer wall of the frame 1, that is, the outer wall not exposed outside the function card slot, and a slot can be set on the inner wall of the function card slot to realize the movable engagement between the expansion card module and the function card slot. The buckle 5 and the slot can be designed and selected according to actual needs, and can be, but are not limited to, a locking structure for pressing a drawer. This setting can be easily understood by those skilled in the art, and will not be elaborated on here.
[0055] The adjusting frame 2 can be a rigid structure or a structure with a certain degree of elasticity. It can be a plate-like structure, a block-like structure, an independent structure, a combined structure, etc. The adjusting frame 2 can be made of the same material as the frame 1 or a different material, such as metal, plastic, resin, cardboard, etc. The adjusting frame 2 can be angled relative to the insertion direction of the function card slot to adjust the degree of airflow through the slot. For example, changing the angle of the adjusting frame 2 relative to the insertion direction of the function card slot can change the effective height of the adjusting frame 2 in the height direction of the function card slot. When the effective height of the adjusting frame 2 is higher, more space is occupied in the height direction of the function card slot, corresponding to the air outlet... The smaller the effective opening size or the degree of airflow passage, the more the adjustment frame 2 can move relative to the frame 1 within the frame 1. This can be, but is not limited to, rotation, sliding, etc. For example, when the adjustment frame 2 is a plate-shaped structure, it can be rotated within the frame 1 around the direction perpendicular to the insertion direction of the function card slot to change the angle of the adjustment frame 2 relative to the insertion direction of the function card slot. Another example is when the adjustment frame 2 is a structure of two combined plates. One plate can be rotated within the frame 1 around the direction perpendicular to the insertion direction of the function card slot, and the connection between the two plates can also be rotated around the direction perpendicular to the insertion direction of the function card slot. This allows the other plate to be adjusted by sliding back and forth in the insertion direction of the function card slot to adjust the angle of the first plate relative to the insertion direction of the function card slot. It is not difficult to understand that the first target state and the second target state of the adjustment frame 2 can be the state in which the airflow channel of the function card slot is fully open and completely closed, respectively, or the state in which the airflow channel of the function card slot is half open and 1 / 4 open, respectively. The specific degree of openness can be adapted to the angle, which will not be elaborated here. The target state of the adjustment frame 2 relative to the frame 1 or the function card slot is not limited to the two mentioned above, and the angle can be adjusted according to actual needs.
[0056] As described above, the expansion card module provided in this application adjusts the airflow channel of the function card slot by setting the adjustment bracket 2 to be movable relative to the frame 1 to adjust its angle with the insertion direction of the function card slot. This adjusts the airflow of the function card slot without an inserted card and the flow field inside the electronic device, balances the exhaust resistance and gas flow of all function card slots on the electronic device, reduces the heat dissipation pressure of the fan on the function card slot with an inserted function card 6, and reduces power consumption and energy waste. This solves the problem of energy and cost waste caused by increased fan power consumption in slots without an inserted expansion card on existing servers.
[0057] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.
[0058] Further, see Appendix Figure 1 In the specific implementation of the expansion card module provided in this embodiment, the adjustment frame 2 includes at least one adjustment plate 21; the adjustment plate 21 is rotatably disposed in the frame 1 around the first direction a to switch between the first target state and the second target state; wherein, the first target angle is smaller than the second target angle, and the first penetration degree is greater than the second penetration degree; the first direction a is perpendicular to the insertion direction of the function card slot.
[0059] It is understandable that, in order to achieve the switching between the first target state and the second target state of the adjustment frame 2, in this embodiment, the adjustment frame 2 can be configured to include at least one adjustment plate 21. The adjustment plate 21 can be a straight plate, a wave plate, an arc plate, etc. The number of adjustment plates 21 can be designed and adjusted according to actual needs. For example, the height of a single adjustment plate 21 can be adapted to the height of the function card slot, so only one adjustment plate 21 can be set; for example, the sum of the heights of at least two adjustment plates 21 can be adapted to the height of the function card slot, so at least two adjustment plates 21 can be set sequentially along the height direction of the function card slot for cooperative adjustment. Of course, in the case of multiple adjustment plates 21, the adjustment angles of each can be set to be the same or different as needed. In this embodiment, the initial state of the adjustment plate 21 can be parallel to the insertion direction of the function card slot. As the angle generated by the adjustment plate 21 gradually increases relative to the insertion direction of the function card slot, its obstruction of the airflow channel of the function card slot gradually increases. In this embodiment, the first direction a is perpendicular to the insertion direction of the function card slot and can be the width direction of the function card slot. In this embodiment, the angle adjustment of the adjustment plate 21 can also guide airflow relative to the function card 6 adjacent to the expansion card module in the height direction of the function card slot. (See attached diagram.) Figure 6 The adjustment plate 21 on the lower side of the figure can block the airflow from the function card slot where it is located, but it can direct the airflow that originally passed through the function card slot to the function card 6 below it, so that more airflow is directed to the function card 6, thereby improving the heat dissipation efficiency of the function card 6.
[0060] Further, see Appendix Figure 2 In this embodiment of the expansion card module, the adjustment frame 2 further includes an adjustment member 22; the first side of the adjustment plate 21 is rotatably connected to the frame 1 around a first direction a; the adjustment plate 21 and the adjustment member 22 are arranged sequentially along a second direction b; the second side of the adjustment member 22 is rotatably connected to the fourth side of the adjustment plate 21 opposite to its first side around the first direction a; a first mating member 23 is provided on the third side of the adjustment member 22 opposite to its second side; a plurality of second mating members 11 adapted to the first mating member 23 are provided at intervals along the second direction b on the frame 1; the second mating members 11 and the first mating members 23 can rotate relative to each other; wherein, the first mating member 23 is connected to different second mating members 11 to adjust the insertion direction of the adjustment plate 21 and the function card slot to be at different angles; wherein, the second direction b is opposite to the insertion direction of the function card slot.
[0061] It is understandable that, in order to achieve state switching between the adjustment plate 21 and the frame 1, an adjustment component 22 can be provided in this embodiment. The adjustment component 22 is a rigid structure, which can be a plate-like structure, a rod-like structure, a frame structure, a hook structure, etc. The adjustment component 22 can drive the adjustment plate 21 to switch states. In this embodiment, the first direction a and the second direction b can correspond to the width and length directions of the function card slot, respectively. (See attached diagram.) Figure 1 and attached Figure 2In this embodiment, the frame 1 can be configured to have two opposing frame edges along the length direction of the function card slot and two opposing frame edges along the width direction of the function card slot. The adjustment plate 21 extends along the width direction of the function card slot. The opposing first edge on the adjustment plate 21 can rotate relative to the frame 1 around the first direction a, and the opposing fourth edge can rotate relative to the adjustment member 22 around the first direction a. Thus, when the first mating part 23 of the adjustment member 22 switches to the mating part 11, the distance between the first mating part 23 and the first edge of the adjustment plate 21 is changed. When the first mating part 23 approaches, the fourth edge of the adjustment plate 21 is lifted up, increasing the angle between the adjustment plate 21 and the insertion direction of the function card slot, thereby reducing the degree of airflow passage of the adjustment plate 21 to the function card slot. Conversely, when the first mating part 23 moves away, the fourth edge of the adjustment plate 21 is pulled down, reducing the angle between the adjustment plate 21 and the insertion direction of the function card slot, thereby increasing the degree of airflow passage of the adjustment plate 21 to the function card slot. The first mating member 23 and the second mating member 11 allow relative rotation in the first direction a. In this embodiment, it can be as follows: Figures 2 to 8 As shown, the first mating part 23 and the second mating part 11 are respectively set as a cylinder and a round hole. Alternatively, the first mating part 23 and the second mating part 11 can be set as a sphere and a round hole, or a round hole and a cylinder. It is easy to understand that the first mating part 23 and the second mating part 11 can also be set in a sliding fit along the second direction b, such as the fit between a slider and a groove, allowing the first mating part 23 to slide back and forth in the second direction b to change its distance from the first side of the adjusting plate 21.
[0062] It is understandable that, in order to improve the ease of use of the expansion card module provided in this embodiment, the maximum effective size of the adjustment plate 21 along the thickness direction of the frame 1 can be set to be equal to the height of the function card slot, so that the expansion card module can be matched one-to-one with the function card slot; of course, in this embodiment, the maximum effective size of the adjustment plate 21 along the thickness direction of the frame 1 can also be set to be equal to the height of at least two function card slots, so that when corresponding to multiple adjacent function card slots, one expansion card module can adjust the airflow of multiple function card slots, for example... Figure 3 As shown, this improves adjustment efficiency, reduces the number of expansion card modules used, and lowers costs. Figure 3 The image shows the distribution of three adjacent function card slots in an electronic device, including... Figure 2In one usage state, the expansion card module is installed in the function card slot. In this state, the expansion card module can be inserted into the function card slot to simultaneously block the airflow channels of the two function card slots on the upper side. This can be achieved by adjusting the adjustment bracket 2 before inserting the expansion card module, or by adjusting the adjustment bracket 2 to a supported state after inserting the expansion card module. Of course, it is understandable that when airflow balancing is not required, the adjustment plate 21 can be kept parallel to the insertion direction of the function card slot, i.e. Figure 4 As shown, this configuration avoids affecting the insertion of the adjacent function card 6 and also provides visual obscuring of the function card slot it is located in.
[0063] Further, see Appendix Figure 5 In the specific implementation of the expansion card module provided in this embodiment, the adjustment frame 2 includes two adjustment plates 21; the two adjustment plates 21 are symmetrically arranged along the thickness direction of the frame 1.
[0064] It is understandable that, in order to improve the driving efficiency of the adjustment plates 21, in this embodiment, they can be symmetrically arranged along the thickness direction of the frame 1. In this arrangement, the sum of the maximum effective dimensions of the two adjustment plates 21 along the thickness direction of the frame 1 can be equal to the height of the function card slot. Therefore, under the same target size condition, the size of each adjustment plate 21 can be reduced, lowering the adjustment difficulty and improving the adjustment efficiency. Furthermore, in this arrangement, the two symmetrical adjustment plates 21 can rotate in tandem or independently. For example, when the two adjustment plates 21 are linked, their degree of obstruction of the airflow channel of the function card slot can be adjusted by synchronously moving away from and closer to each other. When the two adjustment plates 21 rotate independently, the adjustability is higher; their degree of obstruction can be the same or different, adapting to scenarios requiring fine-tuning, for example... Figure 6 , Figure 7 and Figure 8 The state shown is as follows. Figure 6 When only the lower adjustment plate 21 is raised to block airflow, and the upper adjustment plate 21 is not raised, the airflow channel of the upper function card slot is not restricted. In this state, the lower adjustment plate 21 can guide airflow to the adjacent function card 6 below to improve its heat dissipation effect. Figure 7 The upper and lower adjustment plates 21 are both raised to completely block the airflow channel of the function card slot. In this state, the airflow that originally passed through the function card slot corresponding to the upper and lower adjustment plates 21 can be adjusted to other function card slots with function cards 6 to improve the airflow and heat dissipation effect. Figure 8 The different degrees of support of the upper and lower adjustment plates 21 allow for the adjustment of the airflow rate of different function card slots to coordinate the overall airflow rate of the electronic device according to actual needs. It is easy to understand that each adjustment plate 21 can be configured in conjunction with the adjustment component 22.
[0065] Further, see Appendix Figure 1 and attached Figure 3 The expansion card module provided in this embodiment also includes a partition 24 in a specific implementation; the partition 24 extends between the two adjustment plates 21 along the insertion direction of the function card slot, and the circumferential edges of the partition 24 are all attached to the inner wall of the frame 1.
[0066] It is understandable that, in order to improve the strength and ease of use of the expansion card module, in this embodiment, a partition 24 can be set in conjunction with two symmetrical adjustment plates 21. The partition 24 is a rigid structure and can be a straight plate or a corrugated plate, as long as it extends along the insertion direction of the function card slot. The partition 24 can serve as a structural support for the frame 1, ensuring the strength of the frame 1 or the expansion card module and preventing the frame 1 from deforming or collapsing along the first direction a and / or the second direction b. The partition 24 can be integrally formed with the frame 1 or can be subsequently connected to the inner wall of the frame 1, and can be, but is not limited to, bonding, screwing, welding, etc. In this setting, the adjustment plates 21 on both sides of the partition 24 can each correspond to the height of the first function card slot or can both correspond to the height of a function card slot. Correspondingly, the dimensions in the thickness direction of the frame 1 can also be designed accordingly. It is also understandable that the setting position and setting size of the partition 24 can be designed and adjusted according to actual needs, such as... Figure 1 The settings for the corresponding frame 1 shown can also be as follows: Figure 3 The dimensions of all lengths corresponding to frame 1 are shown.
[0067] Further, see Appendix Figure 2 The expansion card module provided in this embodiment also includes a limiting member 25 in a specific implementation; the limiting member 25 is disposed inside the frame 1 and is used to abut against the edge of the adjustment plate 21 that is rotatably connected to the frame 1.
[0068] Understandably, in order to improve the stability of the adjusting plate 21 and prevent it from jumping or shifting relative to the frame 1, a limiting member 25 is provided in this embodiment. The limiting member 25 is a rigid structure and can be... Figure 2 The plate shown can also be in the form of a block, frame, etc., as long as it can abut against the adjusting plate 21 to prevent it from changing position. In this embodiment, the limiting member 25 can be set to abut against the first side of the adjusting plate 21. The limiting member 25 can extend from the inner wall of the frame 1 or through the partition 24.
[0069] Further, see Appendix Figure 6 and attached Figure 10In the specific implementation of the extended opening module provided in this embodiment, the first end of the frame 1 is provided with an opening plate 3; the adjustment frame 2 is disposed on the side of the opening plate 3 facing the inside of the frame 1, and at least one adjustment plate 21 is arranged sequentially along the thickness direction of the frame 1 so that at least one adjustment plate 21 can move relative to the frame 1 to adjust the number of openings on the opening plate 3 connected to the airflow channel.
[0070] It is understandable that when the function card slot is located on the front or front end of the electronic device, in order to adapt to the appearance requirements of the electronic device, this embodiment can achieve appearance adjustment and beautification through the setting of the perforated plate 3, avoiding the expansion card module being directly exposed and affecting the overall visual experience; the perforated plate 3 can be a rigid structure, an elastic structure, or a flexible structure, such as a honeycomb panel; it is not difficult to understand that the perforated plate 3 can be the part of the frame 1 facing outwards from the function card slot in the installed state. In this setting method, refer to the attached... Figure 10 The frame 1 can be composed of two opposing frame edges along the width direction of the function card slot and two opposing frame edges along the height direction of the function card slot. The perforated plate 3 simultaneously forms an end sealing plate with two of the four frame edges. The adjusting plate 21 can extend along the width direction of the function card slot and can rotate around the first direction a, i.e., the width direction of the function card slot. Multiple adjusting plates 21 can be arranged sequentially along the height direction of the function card slot. In this embodiment, the dimensions of the adjusting plate 21 can refer to the foregoing description. A single adjusting plate 21 can completely block the height space of the function card slot, or multiple adjusting plates 21 can be used simultaneously to completely block the height space of the function card slot. Figure 11 The state shown can also be such that multiple adjusting plates 21 work together to completely block the height space of multiple adjacent functional card slots. In this configuration, the adjusting plate 21 can form a louver with the perforated plate 3. When the adjusting plate 21 rotates around the first direction a until it is parallel to the perforated plate 3 (i.e., the adjusting plate 21 is at a 90-degree angle to the insertion direction of the functional card slot), all the openings on the perforated plate 3 are blocked by the adjusting plate 21, and the airflow channel of the functional card slot is completely blocked. Correspondingly, as the adjusting plate 21 rotates around the first direction a until it is parallel to the perforated plate 3 (i.e., the angle between the adjusting plate 21 and the insertion direction of the functional card slot gradually decreases to 0 degrees, i.e., perpendicular to the perforated plate 3), the number and degree of blocking of the openings on the perforated plate 3 gradually decrease, and the degree of airflow channel penetration of the functional card slot gradually increases. Accordingly, when there are at least two adjusting plates 21, each adjusting plate 21 can be controlled to move independently or moved synchronously under unified control. In this configuration, the two ends of the adjusting plate 21 along the first direction a can refer to the configuration of the first mating part 23 and the second mating part 11 described above, or refer to the attached... Figure 10 A circular hole is provided on the frame 1, and a cylinder is provided on the adjusting plate 21 to be inserted into and rotated within the circular hole. (See attached diagram for further details.) Figure 13 A first limiting member 26 is provided on the cylinder along its radial extension, and a second limiting member 27 is provided outside the circular hole. When the adjusting plate 21 rotates to a 90-degree angle with the opening plate 3, the first limiting member 26 abuts against the second limiting member 27, reducing the rotatable range of the adjusting plate 21 and improving the driving efficiency of the adjusting plate 21. The first limiting member 26 and the second limiting member 27 can both be rigid structures, or one can be rigid and the other has a certain elasticity to avoid rigid collisions or friction. The first limiting member 26 and the second limiting member 27 can both be plate-shaped structures, or they can be block-shaped structures, spherical structures, etc. In this setting, the adjusting plate 21 can be driven manually, or the cylinder can be driven by a tool with a pre-reserved driving position outside the frame 1. The tool can be, but is not limited to, a screwdriver.
[0071] Further, see Appendix Figure 9 and attached Figure 10 In the specific implementation of the expansion card module provided in this embodiment, at least some of the adjustment plates 21 can be moved to form a target angle with the insertion direction of the function card slot.
[0072] It is understandable that, in order to improve the adjustability of the adjustment frame 2, in this embodiment, at least some of the adjustment plates 21 can be moved to a target angle with the insertion direction of the function card slot, that is, at least some of the adjustment plates 21 can be controlled to rotate independently. For example, when there are two adjustment plates 21, one can rotate flexibly while the other can remain at a certain angle, or the two adjustment plates 21 can rotate to different angles, thereby improving the adjustability of the adjustment frame 2 to meet the requirements of diverse scenarios.
[0073] Example 2
[0074] This embodiment provides an electronic device, which includes a housing 7 and at least one expansion card module. The housing 7 has a receiving space and is provided with a plurality of function card slots communicating with the receiving space. The at least one expansion card module is movably disposed at the function card slot.
[0075] The expansion card module includes a frame 1 and an adjustment bracket 2. The frame 1 is adapted to the function card slot of the electronic device and is movably disposed at the function card slot. The adjustment bracket 2 is movably disposed within the frame 1. The adjustment bracket 2 has a first target state and a second target state relative to the frame 1. When the adjustment bracket 2 is in the first target state, the adjustment bracket 2 forms a first target angle with the insertion direction of the function card slot, so that the airflow channel of the function card slot reaches a first degree of penetration. When the adjustment bracket 2 is in the second target state, the adjustment bracket 2 forms a second target angle with the insertion direction of the function card slot, so as to adjust the airflow channel of the function card slot to a second degree of penetration. The second degree of penetration is different from the first degree of penetration.
[0076] The electronic device provided in this embodiment may be, but is not limited to, server chassis, desktop chassis, and other electronic devices. Such electronic devices have multiple function card slots at the front or rear. The function card slots provide a medium for electrical connection between expansion cards or function cards and the motherboard of the electronic device. They allow expansion cards or function cards to be inserted into the slots to achieve connection with the motherboard. This configuration is easily understood by those skilled in the art.
[0077] The expansion card module provided in this embodiment is the same as the expansion card module described in Embodiment 1. Its structure and working principle are detailed in Embodiment 1 and will not be elaborated further here. When the expansion card module is used in conjunction with the function card slots of an electronic device, the airflow passage of the corresponding function card slot can be adjusted by switching the state of the adjustment bracket 2 within the frame 1. This adjusts the airflow of the inserted function card slot. For electronic devices with multi-function card slots, the expansion card module can increase or adjust the airflow resistance of the function card slot without an inserted function card 6 as needed. This forces the cooling fluid blown out of the electronic device to pass through the function card slot with the inserted function card 6, thereby balancing the airflow resistance and airflow of each function card slot, improving heat dissipation efficiency, and reducing the power consumption of the fan inside the electronic device.
[0078] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
