Description

Technical Field

[0001] This invention relates to the field of air-cooled heat dissipation, and more particularly to an adjustable cooling device. Furthermore, this invention also relates to a server. Background Technology

[0002] With the increasing power consumption of server components and parts, improving the efficiency of heat dissipation for heat-generating components within servers is crucial. Current server air-cooling designs rely on forced convection provided by air-cooled fans, which are fixed within the system and cannot be moved. However, the position of these fans directly impacts the cooling effect for heat-generating components or devices on the motherboard. Furthermore, the location of cooling devices varies across different system architectures, requiring customized cooling designs for each system structure, resulting in poor versatility.

[0003] For those skilled in the art, designing a precise and versatile air-cooled structure is a technical problem that needs to be solved. Summary of the Invention

[0004] This invention provides an adjustable cooling device that can adjust the position of the air-cooled heat sink, allowing the fan to be positioned in different locations according to heat dissipation needs. This improves the precision of heat dissipation and makes it applicable to server equipment of different sizes, thus enhancing its versatility. The specific solution is as follows:

[0005] An adjustable cooling device includes:

[0006] A fixed support and positioning base is installed in the cooling position; a movable position adjustment support assembly is movably installed on the fixed support and positioning base and can be moved relative to the fixed support and positioning base in a direction perpendicular to the airflow to adjust its position; the movable position adjustment support assembly is used to install the air-cooled heat sink; a positioning component is used to lock the position of the movable position adjustment support assembly.

[0007] The movable position adjustment support assembly is used to install air-cooled heatsinks. When the movable position adjustment support assembly moves relative to the fixed support positioning base, it drives the air-cooled heatsink to move synchronously relative to the fixed support positioning base. The position of the movable position adjustment support assembly is the same as the position of the air-cooled heatsink, which can adjust the air-cooled heatsink to the optimal cooling position, thereby achieving precise position adjustment in a single module. Moreover, this structure can be adapted to accommodate more server specifications by adjusting the air-cooled heatsink.

[0008] Optionally, the fixed support positioning base includes two parallel translation guide rails; the movable position adjustment support assembly includes a fan connecting support plate and two sets of rolling support wheels, each set of rolling support wheels being able to roll along one of the translation guide rails.

[0009] The two tracks together provide support for the movable position adjustment support assembly, which can move along the extension direction of the two tracks 11. The position can be adjusted to any position through the cooperation of the translation guide track and the rolling support wheel, and the position of the air-cooled heat sink can be adjusted steplessly.

[0010] Optionally, the rolling support wheel includes a toothed rolling wheel and an axial position limiting wheel, wherein the outer diameter of the toothed rolling wheel is smaller than the outer diameter of the axial position limiting wheel; a rack is provided on the upper surface of the translational guide rail, and the toothed rolling wheel meshes with the rack; the axial position limiting wheel limits the toothed rolling wheel from the side.

[0011] The axis of the toothed rolling wheel and the axis of the axial position limiting wheel are on the same straight line; the outer diameter of the toothed rolling wheel is smaller than the outer diameter of the axial position limiting wheel. The toothed rolling wheel and the axial position limiting wheel together form the entire rolling support wheel. The cross-section of the rolling support wheel is "convex" shaped. It is supported by the toothed rolling wheel and limited by the axial position limiting wheel.

[0012] Optionally, the fixed support positioning base includes an annular axial position limiting frame, wherein the width of the limiting channel of the annular axial position limiting frame is smaller than the outer diameter of the axial position limiting wheel and larger than the outer diameter of the toothed rolling wheel.

[0013] The limiting channel is a flat and elongated channel that runs horizontally through the entire structure. The direction of the limiting channel is perpendicular to the moving direction of the movable position adjustment support assembly. The length of the limiting channel extends along the moving direction of the movable position adjustment support assembly, thereby achieving better axial limiting.

[0014] Optionally, vibration-reducing pads are provided on the bottom and sides of the fixed support positioning base.

[0015] Vibration damping pads are located between the fixed support positioning base and the chassis. The vibration damping pads form a gap and absorb the vibration of the fixed support positioning base, thereby reducing the vibration experienced by the chassis and preventing the vibration from being transmitted to other components inside the chassis, thus avoiding any impact on the normal operation of other components.

[0016] Optionally, the positioning component is a magnet, which is used to achieve adsorption and locking with the fixed support positioning base or the surface on which the fixed support positioning base is mounted.

[0017] The movable position adjustment support assembly can be fixed and locked in any position using magnets.

[0018] Optionally, one of the fan connecting support plates connects two sets of rolling support wheels; the magnet is fixed to the bottom of the fan connecting support plate.

[0019] Only one fan connection support plate is provided, and all rolling support wheels are connected through one fan connection support plate to ensure that the fan connection support plate and the rolling support wheels move synchronously.

[0020] Optionally, a fan connection protrusion support is provided on the upper surface of the fan connection support plate, and the fan connection protrusion support is connected to the air-cooled heat sink via a connecting pin.

[0021] Optionally, the length of the translation guide rail is sufficient to allow the four air-cooled radiator fans to move and adjust their positions.

[0022] It can meet the position adjustment needs of different air-cooled heat sinks.

[0023] The present invention also provides a server including the adjustable cooling device described in any of the preceding claims.

[0024] This invention provides an adjustable cooling device, including a fixed support and positioning base, a movable position adjustment support assembly, and a positioning component. The fixed support and positioning base is installed at the cooling position, i.e., the position where airflow is required for heat dissipation. The movable position adjustment support assembly is movably installed on the fixed support and positioning base and can translate relative to the fixed support and positioning base in a direction perpendicular to the airflow direction. A fan is installed on the movable position adjustment support assembly and moves synchronously with the movable position adjustment support assembly, changing the position of the fan. The positioning component locks the position of the movable position adjustment support assembly. Once the fan is in position, the positioning component locks the movable position adjustment support assembly to prevent the fan from moving arbitrarily. This invention enables fan position adjustment, placing the fan in the optimal position, improving heat dissipation accuracy, and is compatible with different equipment models, exhibiting strong versatility.

Detailed Implementation

[0038] The core of this invention is to provide an adjustable cooling device that can adjust the position of the air-cooled heat sink, improve the accuracy of heat dissipation, and enhance versatility.

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the adjustable cooling device of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This invention provides an adjustable cooling device, combined with Figure 1 , Figure 1 This is a front view of the adjustable cooling device of the present invention; it includes a fixed support and positioning base 1, a movable position adjustment support assembly 2, a positioning assembly, and other structures. The fixed support and positioning base 1 is installed at the cooling position and serves as a support structure, which is the load-bearing part of the entire adjustable cooling device. The fixed support and positioning base 1 is a fixed structure, and the position of the entire adjustable cooling device is positioned by using the fixed support and positioning base 1, that is, the fixed support and positioning base 1 is installed at the position where cooling is required.

[0041] Adjustable cooling devices are mainly used in servers, computer mainframes, etc., typically at the air intake of the entire chassis, and can also be used near certain heat-generating components, such as CPUs and GPUs. Generally, a fixed support and positioning base 1 is installed onto the bottom surface inside the chassis. The fixed support and positioning base 1 can be fixed or detachable, for example, by welding, binding, or bolting; all these specific methods should be included within the scope of this invention. A detachable connection is preferred; for example, connecting holes are provided in the fixed support and positioning base 1, and several bolts are used to install the fixed support and positioning base 1 onto the chassis.

[0042] There are no strict requirements on the shape of the fixed support and positioning base 1, as long as it can provide support and guidance. The fixed support and positioning base 1 is usually made of metal to ensure sufficient support strength, while also having a certain degree of thermal conductivity.

[0043] The movable position adjustment support assembly 2 is movably mounted on the fixed support positioning base 1. The movable position adjustment support assembly 2 and the fixed support positioning base 1 are not a fixed structure; the movable position adjustment support assembly 2 can translate relative to the fixed support positioning base 1. The fixed support positioning base 1 provides guiding displacement for the movable position adjustment support assembly 2. The movable position adjustment support assembly 2 moves relative to the fixed support positioning base 1 in a direction perpendicular to the airflow. Figure 1 As shown, the movable position adjustment support assembly 2 moves in the direction indicated by the bidirectional arrows in the figure, and can reciprocate in the left and right directions, with the airflow direction perpendicular to the paper surface.

[0044] The specific structure of the movable position adjustment support assembly 2 is not strictly limited, as long as it provides stable support for the air-cooled heat sink.

[0045] The movable position adjustment support assembly 2 is used to install the air-cooled heat sink 3. When the movable position adjustment support assembly 2 moves relative to the fixed support positioning base 1, it drives the air-cooled heat sink 3 to move synchronously relative to the fixed support positioning base 1. The position of the movable position adjustment support assembly 2 is the same as the position of the air-cooled heat sink 3.

[0046] The positioning component is used to lock the position of the movable position adjustment support assembly 2. The positioning component can adopt different configurations, the specific configuration of which will be specified later. The positioning component is not shown in the accompanying drawings. Through the cooperation between the movable position adjustment support assembly 2 and the fixed support positioning base 1, the position adjustment of the movable position adjustment support assembly 2 can be achieved, such as... Figure 1 When the movable position adjustment support assembly 2 is adjusted to the correct position, it is necessary to keep the movable position adjustment support assembly 2 and the position of the air-cooled cooling fan 3 locked to prevent unnecessary movement of the movable position adjustment support assembly 2 and the air-cooled cooling fan 3, so that the air-cooled cooling fan 3 is kept in the set position.

[0047] Specifically, the relative relationship between the movable position adjustment support assembly 2 and the fixed support positioning base 1 provided by this invention can be steplessly adjustable or set with several positions, i.e., discrete positioning. Stepless adjustment allows the movable position adjustment support assembly 2 and the air-cooled heat sink 3 to be positioned at any position within a certain range, providing good adjustability. Therefore, the movable position adjustment support assembly 2 and the fixed support positioning base 1 are typically assembled with stepless adjustment. However, this invention does not preclude the fixed support positioning base 1 from having several positions, allowing the movable position adjustment support assembly 2 to be locked in different positions.

[0048] The adjustable cooling device of this invention allows for adjustment of the position of the air-cooled fans within the system. Adjusting this position can increase heat dissipation efficiency, for example, by aligning them with heat sources on different motherboards, and allowing a single chassis to accommodate different motherboards. The adjustable cooling device of this invention can be adapted to chassis of different sizes using an air-cooled fan bracket, provided the chassis' maximum dimensions are similar or as needed. This design improves the efficiency of zone-based cooling control.

[0049] In use, first install the fixed support positioning base 1 into the system, and then adjust the position of the movable position adjustment support assembly 2 on the fixed support positioning base 1; alternatively, first adjust the position of the movable position adjustment support assembly 2 on the fixed support positioning base 1, and then install the fixed support positioning base 1 into the system. Once the position of the air-cooled cooling fan 3 is adjusted to the correct position, use the positioning component to lock the movable position adjustment support assembly 2, preventing the movable position adjustment support assembly 2 and the air-cooled cooling fan 3 from moving arbitrarily. This adjustable cooling device of the present invention can realize the position adjustment of the air-cooled cooling fan, placing it in the optimal position, improving heat dissipation accuracy, and can be matched with different models of equipment, exhibiting strong versatility.

[0050] Combination Figure 4 , Figure 5 , Figure 4 A top view of the structure of the fixed support positioning base and the movable position adjustment support base assembly working together; Figure 5 This is a side view of the fixed support positioning base and the movable position adjustment support assembly working together. Based on the above scheme, the fixed support positioning base 1 of this invention includes two parallel translation guide rails 11. The two rails 11 together provide support for the movable position adjustment support assembly 2, which can move along the extending direction of the two rails 11. Combined with... Figure 4 Two tracks 11 extend laterally in the left-right direction. The upper surface of the tracks 11 is a smooth and complete surface. The movable position adjustment support assembly 2 moves laterally in the left-right direction on the two tracks 11. Each track 11 is equivalent to a protruding crossbar, which creates a gap between the movable position adjustment support assembly 2 and the bottom surface of the chassis.

[0051] To cooperate with the track 11, the movable position adjustment support assembly 2 of the present invention includes a fan connecting support plate 21 and two sets of rolling support wheels 22, each set of rolling support wheels 22 being able to roll along a translational guide track 11. Figure 4 As shown, two sets of rolling support wheels 22 are provided, and each set of rolling support wheels 22 includes two independent rolling support wheels. Figure 4 The CCP exhibits four rolling support wheels 22. These wheels, positioned in pairs on different translational guide rail components 11, are connected by two connecting rods. Each connecting rod has a rolling support wheel 22 rotatably mounted at both ends. Each rolling support wheel 22 can rotate relative to the connecting rod to achieve rolling along the translational guide rail component 11. A fan connecting support plate 21 is fixed between the two connecting rods, providing support for the air-cooled cooling fan.

[0052] It should be noted that the present invention preferably employs a translational guide rail component 11. Translational movement is achieved through the cooperation of the translational guide rail component 11 and the rolling support wheel 22. This cooperation allows for adjustment to any position, i.e., stepless adjustment of the position of the air-cooled radiator fan 3. Alternatively, several notches can be provided on the upper surface of the translational guide rail component 11 to position the movable position adjustment support assembly 2. However, this method only allows for a limited number of positions, limiting the adjustment range. Nevertheless, this specific configuration should also be included within the scope of protection of the present invention.

[0053] Combination Figure 6 , Figure 6 This is a schematic diagram of a rolling support wheel. The rolling support wheel 22 of the present invention includes a toothed rolling wheel 221 and an axial position limiting wheel 222. The toothed rolling wheel 221 and the axial position limiting wheel 222 are coaxially mounted, that is, the axis of the toothed rolling wheel 221 and the axis of the axial position limiting wheel 222 are on the same straight line. The outer diameter of the toothed rolling wheel 221 is smaller than the outer diameter of the axial position limiting wheel 222. The toothed rolling wheel 221 and the axial position limiting wheel 222 together form the entire rolling support wheel 22. The cross-section of the rolling support wheel 22 is convex, and a ring-shaped step is formed between the toothed rolling wheel 221 and the axial position limiting wheel 222. A ring of teeth is provided on the outer periphery of the toothed rolling wheel 221. The outer periphery shape of the axial position limiting wheel 222 is not limited and can be a smooth cylindrical surface.

[0054] A rack is provided on the upper surface of the translation guide rail component 11, that is, a number of teeth are provided on the upper surface of the translation guide rail component 11. The toothed rolling wheel 221 meshes with the rack on the upper surface of the translation guide rail component 11. When the rolling support wheel 22 rolls relative to the translation guide rail component 11, the teeth on the outer periphery of the toothed rolling wheel 221 continuously change the meshing contact state with the teeth on the upper surface of the translation guide rail component 11.

[0055] Combination Figure 6 Because the outer circumference of the toothed rolling wheel 221 meshes with the upper surface of the translational guide rail 11, and the outer diameter of the axial position limiting wheel 222 is larger than the outer diameter of the toothed rolling wheel 221, the side of the axial position limiting wheel 222 close to the toothed rolling wheel 221 contacts the side of the translational guide rail 11, thus limiting the toothed rolling wheel 221 from the side. Figure 6 , Figure 6In the structure shown, the axial position limiting wheel 222 is located outside the toothed block rolling wheel 221. The two toothed block rolling wheels 221 are located directly above the translation guide rail 11, and the axial position limiting wheel 222 is located to the side of the translation guide rail 11. The two axial position limiting wheels 222 are respectively located outside the two translation guide rails 11. When the entire movable position adjustment support assembly 2 has a tendency to move to the left, the axial position limiting wheel 222 on the right contacts the translation guide rail 11 on the right to limit the movement. When the entire movable position adjustment support assembly 2 has a tendency to move to the right, the axial position limiting wheel 222 on the left contacts the translation guide rail 11 on the left to limit the movement. The two axial position limiting wheels 222 limit the movement and prevent the toothed block rolling wheel 221 from separating from the translation guide rail 11.

[0056] certainly, Figure 6 The structure shown is only a preferred embodiment; other configurations may also be used. Figure 7 The structure shown, Figure 7 This is a schematic diagram of another structure for a rolling support wheel; Figure 7 The central axial position limiting wheel 222 is located inside the toothed rolling wheel 221, and in this structure, it can also play a limiting role. When the entire movable position adjusting support assembly 2 has a tendency to move to the right, the right axial position limiting wheel 222 contacts the right translation guide rail 11 to play a limiting role; when the entire movable position adjusting support assembly 2 has a tendency to move to the left, the left axial position limiting wheel 222 contacts the left translation guide rail 11 to play a limiting role.

[0057] The rolling support wheel 22 includes an axial position limiting wheel 222 and a toothed rolling wheel 221 that are fixedly connected relative to each other along the axial direction. Figure 6 , Figure 7 The axial position limiting wheel 222 and the toothed rolling wheel 221 form a stepped shape with a sudden change in size. However, it is obvious that the axial position limiting wheel 222 can also be in the form of a conical wheel, etc. These specific implementations should be included within the protection scope of the present invention.

[0058] Both of the above-mentioned specific configurations of the rolling support wheel 22 can serve as limiters and should be included within the scope of protection of this invention.

[0059] Furthermore, the fixed support and positioning base 1 of the present invention includes an annular axial position limiting frame 12, such as... Figure 2 , Figure 3 As shown, Figure 2 This is a front view structural diagram of a fixed support and positioning base; Figure 3It is a front view structural schematic diagram of the cooperation between a fixed support positioning base and a movable position adjustment support seat assembly; the annular axial position limiting frame 12 is square, the outer shape of the annular axial position limiting frame 12 is annular, and a limiting channel is provided in the middle for avoiding the rolling support wheel 22. The annular axial position limiting frame 12 is arranged above the translation guiding rail member 11. The translation guiding rail member 11 and the annular axial position limiting frame 12 are fixedly integrated with each other. The limiting channel is jointly surrounded by the annular axial position limiting frame 12 and the translation guiding rail member 11. The limiting channel is a flat and long channel, which penetrates transversely. The penetration direction of the limiting channel is perpendicular to the moving direction of the movable position adjustment support seat assembly 2, and the length extension direction of the limiting channel is along the moving direction of the movable position adjustment support seat assembly 2.

[0060] Specifically, the width of the limiting channel of the annular axial position limiting frame 12 is smaller than the outer diameter of the axial position limiting wheel 222 and larger than the outer diameter of the tooth block rolling wheel 221. As shown in Figure 6 where H represents the width of the limiting channel, R is the outer diameter of the axial position limiting wheel 222, and r is the outer diameter of the tooth block rolling wheel 221. There is the following relationship: r < H < R. After being assembled in place, the tooth block rolling wheel 221 is located in the limiting channel, and the axial position limiting wheel 222 is located outside the limiting channel. Since the outer diameter of the axial position limiting wheel 222 is larger than the width of the limiting channel, the axial position limiting wheel 222 is on the outside of the annular axial position limiting frame 12. The cooperation between the axial position limiting wheel 222 and the annular axial position limiting frame 12 plays a limiting effect. By setting the annular axial position limiting frame 12, it plays a better cooperation role with the axial position limiting wheel 222, making it easier for the rolling support wheel 22 to maintain stability during movement.

[0061] As shown in Figure 6 、 Figure 7 the width of the annular axial position limiting frame 12 can be smaller than the width of the tooth block rolling wheel 221, the width of the annular axial position limiting frame 12 can be larger than the width of the tooth block rolling wheel 221, and the width of the annular axial position limiting frame 12 can be equal to the width of the tooth block rolling wheel 221. Specifically, the width dimension is not limited, and any size relationship belongs to the scope protected by the present invention.

[0062] As shown in Figure 2Vibration damping pads 13 are respectively provided on the bottom and sides of the fixed support positioning base 1. The vibration damping pads 13 are made of rubber or silicone. The fixed support positioning base 1 is installed inside the chassis. When the air-cooled heat sink 3 is working, it generates vibration. The movable position adjustment support assembly 2 and the fixed support positioning base 1 are in rigid contact. The vibration generated by the air-cooled heat sink 3 is transmitted to the fixed support positioning base 1 through the movable position adjustment support assembly 2. In order to reduce the vibration transmitted from the fixed support positioning base 1 to the chassis, vibration damping pads 13 are respectively provided on the bottom and sides of the fixed support positioning base 1. The vibration damping pads 13 are located between the fixed support positioning base 1 and the chassis, forming a gap. The vibration damping pads 13 absorb the vibration of the fixed support positioning base 1, reduce the vibration received by the chassis, and prevent the vibration from being transmitted to other components inside the chassis, thus avoiding affecting the normal operation of other components.

[0063] Vibration-reducing pads 13 are provided on the side of the fixed support and positioning base 1. The side wall of the fixed support and positioning base 1 will come into contact with the chassis and other parts. In order to avoid the side of the fixed support and positioning base 1 transmitting vibration to the chassis, the present invention provides vibration-reducing pads 13 on the side of the fixed support and positioning base 1. The vibration-reducing pads can effectively reduce the vibration transmitted from the side of the fixed support and positioning base 1 to the chassis.

[0064] In addition to providing vibration reduction pads 13 on the fixed support positioning base 1, a shock-absorbing structure can also be provided between the rolling support wheel 22 and the fixed support positioning base 1. For example, a rubber layer can be provided on the outer periphery of the toothed rolling wheel 221, or a rubber layer can be provided on the rack surface on the upper surface of the translation guide rail 11. These specific embodiments should all be included within the protection scope of the present invention.

[0065] Based on any of the above technical solutions and their combinations, the positioning component of this invention is a magnet. The magnet is used to achieve adsorption and locking with the fixed support positioning base 1 or the surface on which the fixed support positioning base 1 is installed. The magnet is installed on the movable position adjustment support assembly 2. When the fixed support positioning base 1 has a bottom surface, the magnet cooperates with the bottom surface of the fixed support positioning base 1 to achieve adsorption and positioning locking. When the fixed support positioning base 1 does not have a bottom surface, the magnet directly adsorbs and locks with the surface on which the fixed support positioning base 1 is installed (e.g., the bottom surface of the chassis). Because a magnetic positioning method is used, regardless of the position of the movable position adjustment support assembly 2, it can be locked by magnetic attraction without the need for additional operation, which is more convenient. The main advantages of using a magnetic method to fix the air-cooled cooling fan are the flexible air-cooled cooling fan bracket and improved operational convenience.

[0066] The magnet is fixedly installed on the movable position adjustment support assembly 2. However, the present invention does not exclude the magnet being installed in a detachable manner on the movable position adjustment support assembly 2. These specific forms should be included within the protection scope of the present invention.

[0067] Besides using magnets, other methods can be used to lock the movable position adjustment support assembly 2, such as by tightening bolts. However, this method requires manual operation after the position is adjusted to the correct position, which is more complicated.

[0068] The preferred embodiment of this invention achieves positioning through the magnetic attraction of a magnet. By using an ferrous material for the movable position adjustment support assembly 2 or its mounting surface, the movable position adjustment support assembly 2 can be automatically locked in position. The magnet generates friction between the movable position adjustment support assembly 2 and the fixed support positioning base 1 or the surface on which the fixed support positioning base 1 is mounted, thus achieving positioning. When adjusting the position, only a larger force needs to be applied to the movable position adjustment support assembly 2 to overcome its friction, causing relative displacement. After releasing the applied force, the position of the movable position adjustment support assembly 2 is immediately determined without any additional operation, and the magnetic attraction method allows for fixation at any position.

[0069] Combination Figure 4 , Figure 4 This is a top view of the fixed support positioning base and the movable position adjustment support assembly working together. In this invention, one fan connecting support plate 21 connects two sets of rolling support wheels 22. That is, only one fan connecting support plate 21 is provided. Each rolling support wheel 22 is connected to one fan connecting support plate 21 to ensure that the fan connecting support plate 21 and the rolling support wheels 22 move synchronously.

[0070] The magnet is fixed to the bottom of the fan connecting support plate 21. In the preferred embodiment, the magnet adopts a fixed assembly form and is directly fixed to the bottom surface of the fan connecting support plate 21. The magnet is located in the middle position of the fan connecting support plate 21, which ensures that the fan connecting support plate 21 is balanced by force and will not tilt to one side when moving.

[0071] Combination Figure 8 , Figure 9 , Figure 8 A front view schematic diagram of the interaction between the air-cooled cooling fan and the movable position adjustment support assembly; Figure 9This is a front view schematic diagram of the interaction between the air-cooled heatsink and the fan connection support plate. The invention features a fan connection protrusion support 211 protruding from the upper surface of the fan connection support plate 21. The fan connection protrusion support 211 is a protruding structure extending from the upper surface of the fan connection support plate 21. The number of fan connection protrusion supports 211 matches the number of positioning holes on the air-cooled heatsink 3. The positions of the fan connection protrusion supports 211 correspond to the positions of the positioning holes on the air-cooled heatsink 3. Each positioning hole corresponds to one fan connection protrusion support 211. Each fan connection protrusion support 211 has a connecting hole, and each fan connection protrusion support 211 is connected to the air-cooled heatsink 3 via a connecting pin. Figure 10 As shown, Figure 10 This is a front view schematic diagram of the air-cooled cooling fan 3. The air-cooled cooling fan 3 has a total of eight connection holes. Four connection holes are located on each of the front and rear side walls of the air-cooled cooling fan 3, with each connection hole located at one of the four corners of the side wall. During connection, only the four lower connection holes are needed; two connection holes are located at the front and rear of the lower side wall. The connection hole positions of the air-cooled cooling fan 3 are universally configured, and the position of the fan connection protrusion support 211 in this invention is selected to match the connection hole positions of the air-cooled cooling fan 3.

[0072] The fan connection protrusion support 211 can be in the form of bolts, specifically including a bolt and a nut. The nut has a bolt head and a threaded post. The outer surface of the threaded post has external threads, and the inner hole of the nut has internal threads. The internal threads of the threaded post and the external threads of the stud can cooperate to achieve a threaded connection. When connection is required, the stud passes through the connection hole of the air-cooled radiator 3, the bolt head rests on the surface of the air-cooled radiator 3, and is connected to the stud by the nut. Tightening the nut can achieve a fixed connection of the air-cooled radiator 3.

[0073] Of course, in addition to bolt fixing, the present invention can also use rivets or other forms of connection, as well as snap-fit ​​or riveting. However, bolt structure can easily achieve detachable connection and facilitate later maintenance and disassembly. Therefore, bolt connection is the most preferred solution.

[0074] Combination Figure 4 The adjustable cooling device of the present invention has sufficient length for the adjustment of the air-cooled heat sink 3, and the length of the translation guide rail 11 is sufficient for the four air-cooled heat sinks 3 to move and adjust their positions, respectively meeting the position adjustment requirements of different air-cooled heat sinks 3. Each air-cooled heat sink can independently adjust its own position, thereby achieving separate positioning, and each air-cooled heat sink 3 can be in the optimal position, thereby achieving the optimal air supply state.

[0075] The adjustable cooling device provided by this invention utilizes a translational guide rail 11 and a rolling support wheel 22 to achieve a movable structure, enabling adjustment of the position of the air-cooled heatsink 3 to meet the air-cooling needs of different locations. A magnetic positioning and locking method facilitates easy adjustment of the air-cooled heatsink 3's position. Vibration-reducing pads 13 are installed on the fixed support positioning base 1 to achieve vibration damping, reducing the impact of the air-cooled heatsink's vibration on other structures and preventing system problems caused by the fan's vibration. This design is applicable to various computer cases.

[0076] This invention also provides a server including the aforementioned adjustable cooling device, which achieves the same technical effect. By adjusting the position of the air-cooled heat sink 3, precise alignment of different internal components of the server is achieved, resulting in precise cooling. Since the position of the air-cooled heat sink 3 is adjustable, the same adjustable cooling device can be used for different servers. Within a reasonable range, adjustable cooling devices of the same specifications can be used, simplifying server design, reducing manufacturing costs, and facilitating large-scale deployment. Other structural details of this server are available in the prior art and will not be elaborated upon here.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
