[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] The core of the utility model is to provide an anti-spray device, which can prevent the occurrence of spraying when the male and female joint structures are connected. Another core of the utility model is to provide a liquid cooling server including the anti-spray device.

[0047] Please refer to Figure 1 The utility model provides an anti-spraying device for blocking the liquid sprayed from the joint position in the liquid cooling server, comprising a shell 1 and a switch door 2. The shell 1 has a first mounting hole 11 and a second mounting hole 12. The first mounting hole 11 is located on the first end wall of the shell 1 and is used to plug in the first joint 4. The second mounting hole 12 is located on the second end wall of the shell 1 and is used to plug in the second joint. The axis of the first mounting hole 11 is colinear with the axis of the second mounting hole 12. The switch door 2 is rotatably arranged in the cavity of the shell 1 with the first direction as the axis to open or close the second mounting hole 12. It should be noted that the above-mentioned first mounting hole 11 is used to plug in the first joint 4, which can be understood as the first joint 4 is inserted in the first mounting hole 11, and the circumferential surface of the first joint 4 is in contact with the inner wall of the first mounting hole 11. The above-mentioned second mounting hole 12 is used to plug in the second joint, which can be understood as the circumferential surface of the second joint is in contact with the inner wall of the first mounting hole 11 after the second joint is inserted into the second mounting hole 12.

[0048] like Figures 1 to 3 As shown, the hollow shell 1 can be inserted into the first joint 4 through the first mounting hole 11 opened on its bottom wall, so that the device can be installed on the first joint 4, and the top wall of the shell 1 is opened with a second mounting hole 12 whose axis is colinear with the axis of the first mounting hole 11, and the second joint inserted into the second mounting hole 12 can be connected to the first joint 4.

[0049] Furthermore, if Figures 1 to 4 As shown, a rotatable switch door 2 is provided inside the shell 1, and the axial direction of the switch door 2 has a non-zero angle with the axial direction of the first mounting hole 11, such as an angle of 90 degrees or 80 degrees, so that the switch door 2 can be rotated to fit with the end of the second mounting hole 12 located on the inner side of the shell 1 to close the second mounting hole 12, and the switch door 2 can be rotated in the opposite direction to open the second mounting hole 12.

[0050] During assembly, the device is arranged on the first connector 4, that is, the first connector 4 is inserted into the first mounting hole 11. During use, when the second connector is not inserted, the second mounting hole 12 can be closed by the switch door 2. When the second connector needs to be inserted into the first connector 4, the second connector is directly inserted into the second mounting hole 12, and the switch door 2 is abutted by the second connector to push it open. Alternatively, the switch door 2 is opened in advance, and the second connector is inserted into the second mounting hole 12. Then, the second connector located in the second mounting hole 12 is continuously pushed to make it conductively docked with the first connector 4.

[0051] On the one hand, the use of this device can timely block the liquid sprayed from the first connector 4 during the process of plugging the first connector and the second connector together. On the other hand, the second connector can fit the inner wall of the second mounting hole 12, so inserting the second connector into the second mounting hole 12 can effectively block the liquid sprayed from the first connector 4. In summary, the device has a high degree of timeliness in preventing the liquid from being sprayed when the male and female connector docking structures are connected, and can effectively prevent the liquid from being injected into the cabinet, so as to reduce possible damage to the cabinet.

[0052] In some possible embodiments, the free end of the switch door 2 can elastically abut the first joint 4 inserted in the first mounting hole 11 and the second joint inserted into the second mounting hole 12 at the same time to simultaneously open or close the first joint 4 and the second joint. When in use, the second joint is inserted into the second mounting hole 12, and while the switch door 2 is pushed to rotate by the second joint, the elastic structure of the free end of the switch door 2 moves radially along the second joint and the first joint 4. During this process, the free end of the switch door 2 continues to undergo elastic deformation and abuts against part of the end wall of the second joint and the first joint 4 close to the side of the switch door 2 rotation axis to achieve the closure of the part of the opening of the second joint and the first joint 4, while the part of the second joint and the first joint 4 away from the side of the switch door 2 rotation axis is opened, and the opened part of the second joint and the first joint 4 are butted against each other. In the process of pushing the switch door 2, the anti-spraying performance between the second joint and the first joint 4 is further effectively guaranteed.

[0053] In order to improve the pressure resistance of the switch door 2 and prevent damage caused by collision when the second connector is plugged in, on the basis of the above embodiment, the switch door 2 includes an elastic part 21 and a rigid part 22, and the rigid part 22 is rotatably connected to the shell 1; the elastic part 21 is fixedly connected to the rigid part 22, and the free end of the elastic part 21 can be close to or away from the second mounting hole 12, and the top surface of the free end of the elastic part 21 close to the second mounting hole 12 protrudes from the top surface of the rigid part 22 close to the second mounting hole 12, so as to elastically abut the second connector inserted into the second mounting hole 12.

[0054] like Figures 4 to 8 As shown, the part of the switch door 2 connected to the housing 1 is a rigid part 22. The rigid part 22 can be made of a high-pressure resistant alloy structure or a stainless steel structure. Due to the rigidity of the rigid part 22, its high-pressure resistance performance is relatively high.

[0055] An elastic part 21 that can undergo elastic deformation is fixed to the free end of the rigid part 22. The elastic part 21 can be made of a rubber part or a silicone part, so that the elastic part 21 can be close to or away from the second mounting hole 12 when the switch door 2 rotates; and the structure of the free end of the elastic part 21 is opposite to the second mounting hole 12, and the upper surface of the free end of the elastic part 21 protrudes from the upper surface of the rigid part 22 as a whole or the free end structure. When the switch door 2 is in a state of closing the second mounting hole 12, when the second joint is inserted into the second mounting hole 12, the second joint will first contact with the elastic part 21 to achieve buffering.

[0056] In order to further improve the pressure resistance of the switch door 2 and reduce the stress damage when inserting the second joint, on the basis of the above embodiment, the elastic part 21 includes an overlapping part 211 and an elastic contact part 212 injection molded on the rigid part 22, the overlapping part 211 is attached to the bottom surface of the rigid part 22 close to the first mounting hole 11, and the elastic contact part 212 is located at the free end of the rigid part 22, which is used to elastically abut the second joint inserted into the second mounting hole 12; the number of elastic contact parts 212 is greater than or equal to two, and a plurality of elastic contact parts 212 are arranged at intervals, or the number of elastic contact parts 212 is one, and the middle position of the elastic contact part 212 has a groove.

[0057] like Figure 4 As shown, a layer of elastic structure is injected on the lower surface of the rigid part 22 as the overlap part 211, and an elastic elastic contact part 212 is formed on the right side of the free end of the rigid part 22 to abut against the second joint. Optionally, as Figure 7 As shown, the number of the elastic contact portions 212 is greater than or equal to two, and the plurality of elastic contact portions 212 are arranged in a straight line on the side of the overlap portion 211. Optionally, as shown in FIG. Figure 8 As shown, there is only one long elastic contact portion 212 on the side of the overlapping portion 211, and a groove is opened on the upper surface or the lower surface of the elastic contact portion 212. The groove can be a straight groove or a wavy groove, etc., so that after the second joint abuts the elastic portion 21, the elastic contact portion 212 can be folded or relatively rotated to effectively reduce the stress damage during blind error.

[0058] Based on the above embodiment, the rigid part 22 has a conical hole surface 221, and the cross-sectional dimension of the conical hole surface 221 close to the second mounting hole 12 is larger than the cross-sectional dimension of the end close to the first mounting hole 11; the overlapping part 211 has a protruding structure 2111, the elastic part 21 is injection molded on the rigid part 22, and the protruding structure 2111 is snapped into the conical hole surface 221.

[0059] like Figure 4As shown, a conical hole 221 is opened on the rigid part 22 along the thickness direction. When the elastic part 21 is injection molded on the rigid part 22, the original liquid forming the elastic part 21 can flow into the conical hole 221 during the injection molding stage and be fixed to form a snap connection. Such an arrangement is beneficial to the stability of the opening and closing door 2.

[0060] like Figures 4 to 8 As shown, based on the above embodiment, the rigid part 22 is an L-shaped plate; the elastic part 21 is a rectangular plate, and the overlapping part 211 and the elastic contact part 212 are stepped, and the elastic contact part 212 is embedded in the installation groove at the free end of the rigid part 22.

[0061] On the basis of the above embodiment, at least two switch doors 2 are provided between the first mounting hole 11 and the second mounting hole 12 whose axes are colinear, and the free ends of the switch doors 2 are arranged opposite to each other.

[0062] like Figures 1 to 4 As shown, in this embodiment, the free ends of each switch door 2 are relatively arranged between the first mounting hole 11 and the second mounting hole 12 with collinear axes. Optionally, two switch doors 2 are arranged between the first mounting hole 11 and the second mounting hole 12 with collinear axes. When the two switch doors 2 keep the second mounting hole 12 in a closed state, the two switch doors 2 each occupy half of the central angle of the first mounting hole 11. Optionally, three switch doors 2 are arranged between the first mounting hole 11 and the second mounting hole 12 with collinear axes. When the three switch doors 2 keep the second mounting hole 12 in a closed state, the three switch doors 2 each occupy one third of the central angle of the first mounting hole 11. Of course, the number of switch doors 2 between the first mounting hole 11 and the second mounting hole 12 with collinear axes is not limited to the above-mentioned examples, as long as the free ends relative to each switch door 2 can both open and close the second mounting hole 12.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the shell 1 has two first mounting holes 11 and two second mounting holes 12, the axes of the second mounting holes 12 are collinear with the axes of the corresponding plug-in holes, and a switch door 2 is provided between the corresponding first mounting holes 11 and second mounting holes 12 with collinear axes. With such an arrangement, the device is suitable for adjacent first joints 4 on adjacent tube bodies, or adjacent first joints 4 on a tube body, or first joints 4 of a double plug-in structure, etc.

[0064] Of course, in some other possible embodiments, a number greater than or equal to three first mounting holes 11 and second mounting holes 12 are provided on the housing 1 , and the axes of several first mounting holes 11 are collinear with the axes of the corresponding second mounting holes 12 .

[0065] On the basis of the above embodiment, the switch door 2 is provided with a pressing portion 23 , the top wall of the housing 1 has a movable hole 13 , and the pressing portion 23 is movably inserted and protrudes from the movable hole 13 .

[0066] like Figures 1 to 3 As shown, a rectangular or trapezoidal through hole is opened on the top wall of the shell 1 as a movable hole 13, and a rod-shaped or L-shaped rod body is provided on the switch door 2 as a pressing portion 23. The pressing portion 23 passes through the movable hole 13 to protrude to the outside of the shell 1. When the second connector is inserted into the second mounting hole 12, the peripheral edge structure of the second connector first contacts the pressing portion 23 to push the switch door 2 to rotate, and then the second connector is inserted into the second mounting hole 12.

[0067] Further, the pressing portion 23 can be completely immersed in the interior of the movable hole 13. Such a configuration is conducive to pushing the pressing portion 23 to move it into place and avoid affecting the plug-in mating of the first connector 4 and the second connector. It should be noted that there is no limitation on the means for achieving the above functions, as long as it can be achieved. Optional, such as Figures 1 to 5 The pressing portion 23 adopts a bending structure. When the switch door 2 is closed, the longitudinal extension structure of the pressing portion 23 is inserted into the movable hole 13, and the transverse extension structure protrudes from the housing 1 and extends in the transverse direction. The pressing margin d1 of the pressing portion 23 is less than or equal to the pressing margin d2 of the movable hole 13. Figure 1 As shown, the pressing margin d1 of the pressing portion 23 refers to the lateral width of the pressing portion 23 that exceeds the movable hole 13 when the switch door 2 is closed, and the pressing margin d2 of the movable hole 13 refers to the lateral width of the vacant portion of the movable hole 13 when the switch door 2 is closed. Optionally, the pressing portion 23 adopts a straight rod structure, and the pressing portion 23 of a preset length can be immersed in the movable hole 13 during the rotation process.

[0068] On the basis of the above embodiment, the first side of the switch door 2 has a shaft portion 24 extending along the first direction, and the switch door 2 is rotatably disposed on the housing 1 through the shaft portion 24. Figures 4 to 8 As shown, a rotating shaft portion 24 extending along the X direction is provided on one side of the switch door 2 to facilitate the installation of the switch door 2 on the housing 1.

[0069] Optionally, the length of the shaft portion 24 is greater than the dimension of the switch door 2 along the X-direction, and the first end of the shaft portion 24 protrudes from one end of the switch door 2 along the X-direction, and the second end protrudes from the other end of the switch door 2 along the X-direction; optionally, the shaft portion 24 includes a first shaft portion 24 and a second shaft portion 24, the first shaft portion 24 is arranged at one end of the switch door 2 along the X-direction, and the second shaft portion 24 is arranged at the other end of the switch door 2 along the X-direction, etc. It should be noted that the shaft portion 24 is not limited to the above-mentioned examples, as long as the switch door 2 can be rotatably arranged on the shell 1.

[0070] Furthermore, the switch door 2 is connected to the shell 1 through a reset member to assist the switch door 2 in resetting. A reset member is set between the switch door 2 and the shell 1 to assist the switch door 2 in automatically resetting. When in use, after the second connector is pulled out, the switch door 2 can be reset in time under the action of the reset member to prevent liquid from spraying.

[0071] Optionally, the reset member can use positive and negative magnetic poles, the positive magnetic pole is installed on the side of the shell 1 where the second mounting hole 12 is opened, and the negative magnetic pole is installed on the switch door 2. Under the attraction of the positive and negative magnetic poles, the switch door 2 has potential energy close to the side of the shell 1 where the second mounting hole 12 is opened. After the second connector is pulled out, the switch door 2 can be automatically reset.

[0072] Preferably, the reset member is a torsion spring 3, and one end of the torsion spring 3 abuts the switch member, and the other end abuts the housing 1. With this arrangement, the anti-spraying device has a simple structure and is easy to install. It should be noted that the number of torsion springs 3 and their arrangement are not limited. For example, a torsion spring 3 is sleeved on the first and second ends of a rotating shaft portion 24 of a switch door 2, or a torsion spring 3 is sleeved on the first, second and intermediate shaft ends of a rotating shaft portion 24 of a switch door 2, etc., as long as the reset function can be achieved.

[0073] On the basis of the above embodiment, the housing 1 has at least two mounting holes 14, and the plurality of mounting holes 14 are parallel to the first mounting hole 11 and the second mounting hole 12. After assembly, Figure 3 As shown, the installation hole 14 can realize the installation of the device by cooperating with a rod or a strap or other structure at a preset installation position.

[0074] In addition to the above-mentioned anti-spraying device, the present invention also provides a liquid cooling server including the anti-spraying device disclosed in the above-mentioned embodiment. For the structures of other parts of the liquid cooling server, please refer to the prior art and will not be described in detail herein.

[0075] In some possible embodiments, precise sealing design is used to ensure that the coolant does not leak, such as sealing rings. In addition, the cooling pipes and connectors are made of corrosion-resistant and high-pressure resistant structures, and a protective shell is added to the outside of the coolant pipes to enhance the pressure resistance and safety of the system.

[0076] In some possible embodiments, a safety monitoring system and an emergency response mechanism are also included. For example, the safety monitoring system will monitor key parameters such as the pressure, temperature, and flow rate of the coolant in real time. Once an abnormality is detected, the emergency response mechanism will be immediately activated to shut down the cooling system and / or issue an alarm.

[0077] It should be noted that the relational terms such as "first" and "second" mentioned above are merely used to distinguish one entity from other entities, and do not necessarily require or imply any actual relationship or order between these entities; the "upper surface, lower surface" and the directional words "upper, lower, left, right" mentioned above are all defined based on the drawings in the specification.
