[0002] The present application claims priority to the Chinese patent application No. 202411361249.5, filed on September 27, 2024, and entitled "Joint device and liquid cooling device", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present application belongs to the technical field of heat exchange device design, and particularly relates to a joint device and a liquid cooling device. BACKGROUND

[0004] With the improvement of user demand, the performance of some electronic devices (such as servers) is continuously optimized, which results in that the electronic devices generate more heat in work. In order to ensure the working performance of the electronic devices, the user will configure a liquid cooling device for the electronic device.

DETAILED DESCRIPTION

[0014] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0015] The technical solutions disclosed by the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0016] The embodiment of the present application discloses a joint device. The disclosed joint device can be applied to the connection between a liquid cooling device and an electronic device (for example, a server), so as to connect the liquid cooling device and the electronic device, and then make the liquid cooling medium (for example, cooling water, cooling water solution) flow between the liquid cooling device and the electronic device through the joint device, and finally achieve the purpose of cooling. Specifically, the liquid cooling device can include the joint device, and the electronic device can include a joint matching part. The joint device of the liquid cooling device and the joint matching part of the electronic device are connected by plugging, so as to realize the connection between the liquid cooling device and the electronic device. It should be noted that the electronic device herein refers to a device that needs to be cooled by the liquid cooling device, which can be a server, and can also be other devices that generate heat during work and need to be cooled. The embodiment of the present application does not limit the specific type of the electronic device.

[0017] Please refer to FIGS. 1-4. The joint device disclosed by the embodiment of the present application includes a joint 10 and a blowout prevention mechanism 20.

[0018] The joint 10 is the main part of the joint device, and the joint 10 has a liquid passage allowing the liquid cooling medium to pass through. After the liquid cooling device is connected with the electronic device, the liquid cooling medium can flow between the liquid cooling device and the electronic device through the liquid passage of the joint 10. In an embodiment, the joint 10 can be a tubular structure, for example, a circular tubular structure as shown in FIG. 3. The embodiment of the present application does not limit the specific shape of the joint 10, and the joint 10 can also be other shapes having a liquid passage.

[0019] The blowout prevention mechanism 20 is used to prevent the blowout function. The liquid cooling device stores the liquid cooling medium, and the blowout prevention mechanism 20 is used to avoid the liquid cooling medium in the liquid cooling device from being sprayed onto the electronic device before the liquid cooling device is docked with the electronic device or during the maintenance of the electronic device and the liquid cooling device, thereby adversely affecting the electronic device docked therewith.

[0020] The blowout prevention mechanism 20 includes a base 21, a first elastic member 22, a first cover 23, and a second cover 24. The base 21 is the basic component of the blowout prevention mechanism 20, which can provide an installation basis for other components of the blowout prevention mechanism 20. The base 21 is also used to form some functional space. In the embodiment of the present application, the base 21 is provided with a docking avoidance hole 211. During the docking process of the liquid cooling device and the electronic device, the joint 10 will pass through the docking avoidance hole 211 to be connected with the joint matching part of the electronic device by plugging, thereby realizing the docking connection between the liquid cooling device and the electronic device. Or, during the docking process of the liquid cooling device and the electronic device, the joint matching part of the electronic device will pass through the docking avoidance hole 211, thereby realizing the plugging connection with the joint 10, and finally realizing the connection between the liquid cooling device and the electronic device.

[0021] The first cover 23 and the second cover 24 are located in the docking avoiding hole 211, and the first cover 23 and the second cover 24 are rotatably arranged on the base 21, so as to be able to rotate relative to the base 21 to realize the state switching of the anti-spraying mechanism 20. Specifically, the first cover 23 and the second cover 24 are oppositely arranged to be matched to realize the covering of the docking head 10 to avoid the spraying of the liquid cooling medium in the head 10 towards the electronic device.

[0022] The first elastic member 22 connects the first cover 23 and the base 21 and the second cover 24 and the base 21 respectively, so as to be able to apply elastic force to the first cover 23 and the second cover 24 based on the base 21. That is, the first cover 23 and the base 21 can be connected through the first elastic member 22, and at the same time, the second cover 24 and the base 21 can also be connected through the first elastic member 22.

[0023] The anti-spraying mechanism 20 has a first state and a second state. By applying elastic force to the first cover 23 and the second cover 24, the first elastic member 22 is used to drive the first cover 23 and the second cover 24 to rotate, so as to realize the switching of the anti-spraying mechanism 20 from the first state to the second state, and the anti-spraying mechanism 20 can be maintained in the second state.

[0024] When the anti-spraying mechanism 20 is in the first state, the first cover 23 and the second cover 24 are rotated to a position of opening the interface 11 of the head 10. The embodiments of the present application do not limit the implementation manner of switching the anti-spraying mechanism 20 to the first state, as long as the power can drive the first cover 23 and the second cover 24 to rotate to the position of opening the interface 11. As described above, the liquid cooling device and the electronic device can be docked through the insertion of the joint device and the joint matching part, and in the process of docking the electronic device and the liquid cooling device, as the electronic device approaches, the electronic device can directly or indirectly drive the first cover 23 and the second cover 24 to rotate to the position of opening the interface 11, so as not to cover the interface 11.

[0025] When the anti-spraying mechanism 20 is in the second state, the first cover 23 and the second cover 24 are rotated to a position of covering the interface 11 of the head 10, in which case the interface 11 is covered, so as to avoid the spraying of the liquid cooling medium towards the interface 11, and further to avoid the spraying to the electronic device which is docked in the direction of the interface 11. At the same time, as described above, the first elastic member 22 can maintain the anti-spraying mechanism 20 in the second state, so that the first cover 23 and the second cover 24 are in the normally closed state before the liquid cooling device and the electronic device are docked or during the maintenance of the electronic device and the liquid cooling device.

[0026] The joint device disclosed in the embodiments of the present application, the blowout prevention mechanism 20 comprises a first cover 23 and a second cover 24 which are rotatably arranged on the base 21 and connected with the first elastic member 22, so that the first cover 23 and the second cover 24 are rotated to the position of opening the interface 11 of the joint 10 when the blowout prevention mechanism 20 is in the first state, and the first cover 23 and the second cover 24 are driven by the first elastic member 22 to rotate to the position of covering the interface 11 of the joint 10 when the blowout prevention mechanism 20 is in the second state. In this case, since the first cover 23 and the second cover 24 can cover the interface 11, the liquid cooling medium can be prevented from being sprayed from the interface 11 to the electronic device, and the adverse effects caused by the spraying of the liquid cooling medium to the electronic device can be avoided. Under this premise, the first cover 23 and the second cover 24 form a structure similar to a pair of doors to realize the state switching of the blowout prevention mechanism 20 by rotation, and the sizes of the first cover 23 and the second cover 24 are small, so that the space occupied in the rotation process is small, which is beneficial to the miniaturization design of the joint device. Therefore, the joint device disclosed in the embodiments of the present application can solve the problem of large space occupation of the joint device in the related art.

[0027] As described above, the first cover 23 and the second cover 24 form a structure similar to a pair of doors, and when the first cover 23 and the second cover 24 cover the interface 11, the edges matched with each other of the first cover 23 and the second cover 24 form a gap similar to a door gap. In order to better prevent the liquid cooling medium from being sprayed from the interface 11 to the electronic device, in an embodiment, when the blowout prevention mechanism 20 is in the second state, the edges matched with each other of the first cover 23 and the second cover 24 can form a labyrinth gap 60. The labyrinth gap 60 is essentially a bent gap, and in this case, the edges matched with each other of the first cover 23 and the second cover 24 form a bent gap, so that even if the liquid cooling medium flows out from the gap between the first cover 23 and the second cover 24 after the interface 11 is covered, the liquid cooling medium is not easy to be sprayed to the electronic device due to the bending guide of the labyrinth gap.

[0028] In the embodiment in which the edges matched with each other of the first cover 23 and the second cover 24 form the labyrinth gap 60, the edges matched with each other of the first cover 23 and the second cover 24 are at least not flush edges, so that the jamming problem is easy to occur in the process of the first cover 23 and the second cover 24 rotating to the position of covering the interface 11. Based on this, in a further embodiment, the distance between the rotation axis of the first cover 23 and the central axis of the joint 10 (i.e. the central axis of the interface 11) is a first distance. The distance between the rotation axis of the second cover 24 and the central axis of the joint 10 is a second distance. The first distance and the second distance can be different. This structure can make the first cover 23 and the second cover 24 rotate to the position of covering the interface 11 in turn in the process of rotation, so that the jamming phenomenon between them can be better avoided. It should be noted that the central axis of the joint 10 is shown by a dashed line in FIG. 4.

[0029] There are various ways to achieve the rotational connection between the first cover 23 and the base 21, and similarly, there are various ways to achieve the rotational connection between the second cover 24 and the base 21, and the embodiments of the present application are not limited. In one embodiment, the base 21 can be provided with a first shaft hole 212 and a second shaft hole 213. The first cover 23 can include a first connecting shaft 231, and the second cover 24 can include a second connecting shaft 241. The first cover 23 is rotationally connected to the base 21 by the rotational fit of the first connecting shaft 231 and the shaft hole of the first shaft hole 212. The second cover 24 is rotationally connected to the base 21 by the rotational fit of the second connecting shaft 241 and the shaft hole of the second shaft hole 213. In other embodiments, the first shaft hole 212 and the first connecting shaft 231 can be interchanged, and the second shaft hole 213 and the second connecting shaft 241 can be interchanged.

[0030] In the embodiment in which the edges of the first cover 23 and the second cover 24 cooperate to form the labyrinth gap 60, the structures of the first cover 23 and the second cover 24 can not be the same, and in order to avoid being installed in reverse, the shaft diameters of the first connecting shaft 231 and the second connecting shaft 241 can not be equal, and correspondingly, the diameters of the first shaft hole 212 and the second shaft hole 213 can also not be equal. The shaft diameter of the first connecting shaft 231 can be adapted to the diameter of the first shaft hole 212, thereby achieving the rotational connection therebetween. The shaft diameter of the second connecting shaft 241 can be adapted to the diameter of the second shaft hole 213, thereby achieving the rotational connection therebetween. Such a design of unequal shaft diameters can enable the corresponding components to be foolproof during assembly.

[0031] As described above, in the process of docking the electronic device with the liquid cooling device, as the electronic device approaches, the electronic device can indirectly drive the first cover 23 and the second cover 24 to rotate to a position that opens the interface 11. Based on this, in one embodiment, the base 21 can have a first side and a second side distributed in opposite directions. It should be noted that the first side is the side of the base 21 facing the electronic device. The base 21 can be in sliding fit with the connector 10. The sliding of the base 21 relative to the connector 10 achieves the switching of the anti-spray mechanism 20 between the first state and the second state. When the anti-spray mechanism 20 is in the first state, the end of the connector 10 where the interface 11 is located pushes open the first cover 23 and the second cover 24, and extends to the first side of the base 21 through the docking avoidance hole 211. In this case, the end of the connector 10 where the interface 11 is located can push open the first cover 23 and the second cover 24, thereby achieving the opening of the interface 11. In this case, the end of the connector 10 where the interface 11 is located can extend to the first side of the base 21, so the connector 10 is suitably designed as a male plug, and the connector fitting part is suitably designed as a female plug.

[0032] When the blowout prevention mechanism 20 is in the second state, the end of the joint 10 where the interface 11 is located is retracted into the docking avoidance hole 211 or is retracted to the second side of the base 21 through the docking avoidance hole 211, so that the first elastic member 22 drives the first cover 23 and the second cover 24 to rotate to a position covering the interface 11. In this case, the interface 11 cannot spray the liquid cooling medium to the electronic device due to being covered.

[0033] The working process of the joint device disclosed in this embodiment is as follows: the operator places the electronic device on the equipment rack and pushes the electronic device to move along the track on the equipment rack, thereby gradually approaching the liquid cooling device on the back side of the electronic device. As the electronic device continues to move, the electronic device will contact the base 21 and push the base 21 to move together, thereby enabling the base 21 to slide along the joint 10. In this process, the joint 10 and the base 21 move relatively, so that the end of the joint 10 where the interface 11 is located pushes open the first cover 23 and the second cover 24 and extends to the first side of the base 21 through the docking avoidance hole 211. In this case, the end of the joint 10 where the interface 11 is located needs to overcome the elastic force exerted by the first elastic member 22 on the first cover 23 and the second cover 24 to push open the first cover 23 and the second cover 24. During the movement of the electronic device, the joint fitting part of the electronic device also moves, thereby being able to be inserted into the end of the interface 11 extending to the first side of the base 21, thereby realizing the communication between the liquid cooling device and the electronic device. In this process, the approach of the electronic device to the liquid cooling device can drive the base 21 to move, thereby indirectly opening the first cover 23 and the second cover 24 through the relative movement of the base 21 and the joint 10. As can be seen, this structure can make full use of the approach of the electronic device to the liquid cooling device along the track to realize the installation operation on the rack, not only realizing the blind insertion between the joint fitting part of the electronic device and the joint device of the liquid cooling device to realize the connection, but also realizing the switching of the blowout prevention mechanism 20 to the first state through the movement of the base 21 relative to the joint 10.

[0034] At the same time, the base 21 can move along the joint 10 in a retracted manner during the approach of the electronic device to the liquid cooling device, thereby better playing the role of retraction, so that the electronic device and the liquid cooling device can be closer to each other after being docked during the approach of the electronic device to the liquid cooling device, thereby ensuring that the layout of the electronic device and the liquid cooling device after being docked is more compact.

[0035] Before the electronic device and the liquid cooling device are assembled or during the maintenance of the electronic device and the liquid cooling device, the electronic device and the liquid cooling device are not docked, and the base 21 is not pressed by the electronic device. The base 21 can be moved by the force applying mechanism or manually, so that the base 21 can move relative to the joint 10 in the direction of the first side of the base 21. In this case, the joint 10 also moves relative to the base 21, and the end where the interface 11 of the joint 10 is located is retracted into the docking avoidance hole 211 or through the docking avoidance hole 211 to the second side of the base 21. In this case, the end where the interface 11 of the joint 10 is located does not act on the first cover 23 and the second cover 24, so that the first elastic member 22 is deformed to drive the first cover 23 and the second cover 24 to rotate to a position covering the interface 11.

[0036] The docking avoidance hole 211 has a first aperture facing the first side and a second aperture facing the second side. The first cover 23 and the second cover 24 can be rotatably arranged at the first aperture, or rotatably arranged at the second aperture, or rotatably arranged between the first aperture and the second aperture, and the embodiments of the present application are not limited thereto. In an optional solution, the first cover 23 and the second cover 24 are both rotatably arranged at the second aperture. When the anti-spraying mechanism 20 is in the first state, the end where the interface 11 of the joint 10 is located extends to the first side of the base 21 through the first aperture. When the anti-spraying mechanism 20 is in the second state, the end where the interface 11 of the joint 10 is located is retracted to the second side of the base 21 through the second aperture. In this structure, the electronic device needs to drive the base 21 to move a greater distance during the process that the end where the interface 11 of the joint 10 is located extends to the first side of the base 21 through the first aperture, which is beneficial to the base 21 to implement greater avoidance, and is beneficial to the cooperation between the liquid cooling device and the electronic device after docking to be more compact. In the case that the joint 10 is designed as a male plug, the base 21 implementing greater avoidance means that the relative movement between the base 21 and the joint 10 is a greater distance, so that the joint 10 extends out of the first side of the base 21 longer, which is more beneficial to the subsequent plug-in cooperation of the joint cooperation part of the electronic device.

[0037] As mentioned above, the electronic device can also directly drive the first cover 23 and the second cover 24 to rotate to the position of opening the interface 11 as the electronic device approaches. Based on this, in another embodiment, the base 21 has a first side and a second side distributed in opposite directions. The first side is the side of the base 21 facing the electronic device, and is also the side of the base 21 facing away from the mounting seat 40 mentioned below. The docking avoidance hole 211 has a first aperture facing the first side and a second aperture facing the second side. The end of the interface 11 of the connector 10 extends into the docking avoidance hole 211 from the second aperture, and the first cover 23 and the second cover 24 are both rotatably arranged at the first aperture. During the docking of the electronic device and the liquid cooling device, as the electronic device approaches, the connector fitting part of the electronic device can first extend into the first aperture and push open the first cover 23 and the second cover 24, and as the electronic device further approaches, the connector fitting part of the electronic device will extend into the interface 11 of the connector 10 and realize plugging with the interface 11. In this case, the connector fitting part can extend into the first aperture, and the connector fitting part is suitably designed as a male plug, and the corresponding connector 10 is suitably designed as a female plug. During this process, the connector fitting part of the electronic device pushes open the first cover 23 and the second cover 24 and overcomes the elastic force of the first elastic member 22 applied to the first cover 23 and the second cover 24. Before the electronic device and the liquid cooling device are assembled or during the maintenance of the electronic device and the liquid cooling device, the electronic device and the liquid cooling device are not docked, and the connector fitting part will not push open the first cover 23 and the second cover 24 due to the approach of the electronic device to the liquid cooling device. The first cover 23 and the second cover 24 are in the position of covering the interface 11 under the elastic force of the first elastic member 22. Alternatively, the first cover 23 and the second cover 24 can cover the first aperture, thereby realizing the covering of the interface 11 opposite to the first aperture.

[0038] Of course, in this case, the end of the interface 11 of the connector 10 extends into the docking avoidance hole 211 from the second aperture, thereby facilitating the assemblability between the connector 10 and the base 21. In an alternative of this embodiment, the end of the interface 11 of the connector 10 can also not extend into the docking avoidance hole 211.

[0039] In this embodiment, the base 21 can be fixedly connected with the connector 10 or movably connected with the connector 10. In a further embodiment, the base 21 can be slidably connected with the connector 10. In the process of this embodiment, as the connector fitting portion pushes open the first cover 23 and the second cover 24 at the first aperture, the electronic device continues to approach the liquid cooling device and can also push the base 21 to move towards the second side relative to the connector 10, which not only makes the distance between the electronic device and the liquid cooling device closer after the connection to improve the compactness of the assembly, but also makes the connector fitting portion not be blocked by the base 21 to cause the connection stability problem due to the insufficient depth of the connector fitting portion inserted into the connector 10. Similarly, before the electronic device and the liquid cooling device are assembled or during the maintenance of the electronic device and the liquid cooling device, the electronic device and the liquid cooling device are not connected, and the base 21 moves towards the direction of the first side relative to the connector 10 under the action of the manual operation of the operator or the force applying mechanism.

[0040] In the embodiment in which the base 21 is slidably connected with the connector 10, in order to facilitate the movement of the base 21 towards the direction of the first side relative to the connector 10, the force applying mechanism can be a power telescopic mechanism, such as a pneumatic telescopic mechanism, a hydraulic telescopic mechanism, etc., and the specific type of the force applying mechanism is not limited in the embodiments of the present application. In one embodiment, the connector device disclosed in the embodiments of the present application can further include a second elastic member 30 and a mounting seat 40.

[0041] The mounting seat 40 is used to be connected with the liquid cooling cabinet of the liquid cooling device, and the liquid cooling cabinet is the main part of the liquid cooling device. The connector device can be mounted on the liquid cooling cabinet through the mounting seat 40. The end of the connector 10 opposite to the interface 11 can be fixed to the mounting seat 40 by welding, threaded connection, connecting piece, etc. The second elastic member 30 is elastically supported between the mounting seat 40 and the base 21. The second elastic member 30 is used to drive the base 21 to move towards the direction of the first side relative to the connector 10, so as to realize the reset of the base 21. In the process of connecting the electronic device with the liquid cooling device, as the electronic device gradually approaches, the base 21 moves relative to the connector 10 under the pressure of the electronic device, and this process needs to overcome the elastic force of the second elastic member 30, so that the second elastic member 30 is compressed. In the case that the base 21 is not pressed by the electronic device, the second elastic member 30 is elongated to push the base 21 to reset.

[0042] The second elastic member 30 can be in contact with the mounting seat 40 and the base 21 respectively, or can be connected with the mounting seat 40 and the base 21 respectively, and the embodiments of the present application are not limited, as long as the connection relationship of the second elastic member 30 can play its function. In further embodiments, the joint device can further include a guide rod 51, and the second elastic member 30 can be sleeved outside the guide rod 51, the first end of the guide rod 51 is fixed to the mounting seat 40, the second end of the guide rod 51 passes through the base 21 and extends to the second side of the base 21, and the guide rod 51 is in sliding fit with the base 21. In this embodiment, the guide rod 51 can play a guiding role, and further equivalent to make the base 21 have more sliding basis, so that the sliding of the base 21 is more stable, at the same time, the second elastic member 30 is sleeved outside the guide rod 51, which is beneficial to the deformation of the second elastic member 30 along the extension direction of the guide rod 51, and finally can improve the regularity of the elastic deformation of the second elastic member 30, and achieve better driving effect of the base 21.

[0043] In the embodiments of the present application, the first elastic member 22 and the second elastic member 30 can be a spiral spring, a torsion spring, an elastic rubber member, etc., and the embodiments of the present application do not limit the specific types of the first elastic member 22 and the second elastic member 30.

[0044] In order to avoid the base 21 from being excessively moved and falling off from the end of the joint 10 where the interface 11 is located, the second end of the guide rod 51 can be provided with an anti-falling cap 52, and the anti-falling cap 52 can be arranged at the second end of the guide rod 51 by means of insertion, adhesion, threaded fit or the like. The anti-falling cap 52 is in limiting fit with the base 21. In the process of sliding of the base 21 relative to the joint 10 in the direction of the first side of the joint 10, due to the limiting block of the anti-falling cap 52, the base 21 will not fall off from the guide rod 51, and will not cause the base 21 to fall off from the end of the joint 10 where the interface 11 is located.

[0045] In the embodiments of the present application, the guide rod 51, the second elastic member 30 and the anti-falling cap 52 can be one or multiple, and the embodiments of the present application do not limit the number thereof. In the embodiments in which the guide rod 51, the second elastic member 30 and the anti-falling cap 52 are multiple, the guide rod 51, the second elastic member 30 and the anti-falling cap 52 can correspond one by one. In this embodiment, setting more guide rods 51, second elastic members 30 and anti-falling caps 52 can undoubtedly improve the respective effects.

[0046] The embodiment of the present application does not limit the specific structure of the first elastic member 22. The first elastic member 22 can be a whole structure or a split structure. Since the first cover 23 and the second cover 24 can rotate independently, in order to facilitate assembly and facilitate individual maintenance or replacement, in an embodiment, the first elastic member 22 can include a first sub-elastic member 221 and a second sub-elastic member 222. The first sub-elastic member 221 is connected between the first cover 23 and the base 21, and the second sub-elastic member 222 is connected between the second cover 24 and the base 21. The first sub-elastic member 221 and the second sub-elastic member 222 are respectively used to drive the first cover 23 and the second cover 24 to rotate, so that they cooperate to cover the interface 11. Similarly, the first sub-elastic member 221 and the second sub-elastic member 222 can be torsion springs, and can also be other kinds of elastic members (such as rubber bands). The embodiment of the present application does not limit their specific types.

[0047] In the embodiment of the present application, the base 21 can be a solid structure or a hollow shell structure, and the embodiment of the present application does not limit it. In an embodiment, the base 21 can be a shell structure, and the docking avoidance hole 211 can pass through the two shell walls of the base 21. The first aperture and the second aperture mentioned above can be respectively distributed on the two shell walls of the base 21. The base 21 is provided with a shell cavity 214 communicating with the docking avoidance hole 211, and the first cover 23 and the second cover 24 can be rotatably arranged in the shell cavity 214. The base 21 with such a hollow structure not only can reduce weight to make the connector device lighter, but also can provide sufficient installation space for other components (such as the first cover 23 and the second cover 24).

[0048] In an embodiment, the base 21 can include a bottom shell 201 and a top shell 202. The top shell 202 is detachably connected with the bottom shell 201 and surrounds the shell cavity 214. The first cover 23 can be rotatably connected with the bottom shell 201 and the top shell 202, and the second cover 24 can be rotatably connected with the bottom shell 201 and the top shell 202. The first cover 23 and the second cover 24 are rotatably arranged in the shell cavity 214. The first aperture can be formed on the bottom shell 201 or the top shell 202. Similarly, the second aperture can be formed on the bottom shell 201 or the top shell 202, and the embodiment of the present application does not limit it.

[0049] Considering that the first cover 23 and the second cover 24 are located in the shell cavity 214, it is difficult to ensure that the positions of the first cover 23 and the second cover 24 do not change during the process of covering the top shell 202 on the bottom shell 201. There can be a problem that after the top shell 202 is connected with the bottom shell 201, the positions of the first cover 23 and the second cover 24 cannot be maintained, which causes that the rotational connection between the first cover 23, the second cover 24 and the top shell 202 is prone to failure.

[0050] Based on this, in a further embodiment, the base 21 disclosed by the embodiment of the present application can further comprise a bracket 203 which is detachably connected in the bottom shell 201. The first cover 23 is rotatably connected with the bottom shell 201 and the bracket 203 respectively, and the second cover 24 is rotatably connected with the bottom shell 201 and the bracket 203 respectively. In the process of assembly, since the bracket 203 does not need to form a closed space with the bottom shell 201, the first cover 23 and the second cover 24 can be rotatably connected with the bracket 203, and the bracket 203 can be detachably connected with the bottom shell 201, so as to determine the positions of the first cover 23 and the second cover 24 when the top shell 202 is covered with the bottom shell 201, and further make the first cover 23 and the second cover 24 more easily complete the rotary installation.

[0051] The embodiment of the present application does not limit the detachable connection mode between the top shell 202 and the bottom shell 201, nor the detachable connection mode between the bracket 203 and the bottom shell 201. In order to reduce the number of components, in an embodiment, the top shell 202 and the bottom shell 201 can be detachably buckled through a buckle structure, and similarly, the bracket 203 and the bottom shell 201 can also be detachably buckled through a buckle structure.

[0052] As described above, the base 21 can be provided with the first shaft hole 212 and the second shaft hole 213, and in the embodiment in which the base 21 comprises the bracket 203, the first shaft hole 212 and the second shaft hole 213 can be formed on the bracket 203.

[0053] In the joint device disclosed by the embodiment of the present application, the joint 10 and the blowout prevention mechanism 20 can both be two and correspond one by one. Among the two joints 10, one can be an inflow joint and the other can be an outflow joint. After the liquid cooling device is docked with the electronic device, the liquid cooling medium can flow into the liquid cooling device from the inflow joint and flow out of the liquid cooling device through the outflow joint, so as to realize the cooling circulation of the liquid cooling medium between the liquid cooling device and the electronic device. In this case, the joint fitting part of the electronic device is also two and is inserted into communication with the inflow joint and the outflow joint of the joint device one by one.

[0054] It should be noted that, in the embodiment of the present application, the first cover 23 and the second cover 24 cover the interface 11, which means that the first cover 23 and the second cover 24 are distributed towards the interface 11 and block the liquid cooling medium in the interface 11 from being sprayed onto the electronic device. Specifically, when the blowout prevention mechanism 20 is in the second state, the first cover 23 and the second cover 24 can be sealingly fitted or can not be sealingly fitted, as long as they can block the spraying of the liquid cooling medium towards the interface 11.

[0055] As described above, the first cover 23 and the second cover 24 cover the interface 11 but can not seal the interface 11, in this embodiment, the liquid cooling medium can not be sprayed on the electronic device but is easy to flow out from the interface 11. Based on this, in a further embodiment, the base 21 can include a collection structure for collecting the liquid cooling medium flowing out from the interface 11 and a flow guide structure 204 in communication with the collection structure for guiding away the liquid cooling medium collected by the collection structure. Such a structure can avoid excessive residue of the leaked liquid cooling medium in the joint device. The flow guide structure 204 can be a flow guide groove, a flow guide pipe, etc., and the embodiments of the present application do not limit the specific types of the flow guide structure 204.

[0056] Based on the joint device disclosed in the embodiments of the present application, the embodiments of the present application further disclose a liquid cooling device, which includes a liquid cooling cabinet and the joint device according to any one of the above embodiments. The joint 10 in the joint device is in communication with the liquid cooling cabinet.

[0057] The above embodiments of the present application mainly describe the differences between the embodiments, and the different optimization features of the embodiments can be combined to form a more optimal embodiment as long as they are not contradictory. In view of the brevity of the writing, the details are not described here.

[0058] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not restrictive. Those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims, and all of them belong to the protection of the present application.
