Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, and in particular to an anti-splash device and a liquid cooling cabinet. Background Technology

[0002] Currently, liquid cooling is one method for dissipating heat from equipment (such as servers) inside a server rack. In this liquid cooling system, the server connectors at the equipment terminals and the manifold connectors are mostly connected by blind insertion to improve efficiency and space utilization. In order to prevent abnormal liquid spraying at the two connectors from adversely affecting the equipment inside the rack, anti-spray boxes are added at the connector locations.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the anti-spray box is provided with a rotatable door at the opening of the server connector to prevent the liquid splashed from the manifold connector inserted in the anti-spray box from affecting the server. However, the internal structure of the anti-spray box is compact and its internal space is limited. Moreover, its door does not have a clearance function. That is, when the door is open, and during the process of the manifold connector docking with the server connector, it may collide with the door, resulting in poor reliability.

[0004] Therefore, how to provide a splash-proof device to at least partially solve the above-mentioned drawbacks is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-splash device that can effectively solve the technical problem in the prior art where the manifold connector collides with the door during the docking process with the server connector. This application also provides a liquid-cooled cabinet that includes an anti-splash device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The first aspect of this application provides a splash-proof device, comprising:

[0008] The box body has an internal cavity. The box body includes a first through hole on its first end face for inserting a first connector and a second through hole on its second end face for inserting a second connector, and both of them are in communication with the cavity.

[0009] The door is rotatably mounted on the inner wall of the first end face of the box. The door has a closed position that seals the first through hole and an open position that opens the first through hole. A clearance groove is provided on the surface of the door near the first through hole. The clearance groove is used to make way for the second connector inserted into the second through hole when the door is in the open position.

[0010] In one possible design, the door body includes a first door body and a second door body. A first side of the first door body is rotatably disposed on one side of the first through hole, and a first side of the second door body is rotatably disposed on the other side of the first through hole. When the second side of the first door body and the second side of the second door body are in the closed position, they are mated to seal the first through hole.

[0011] In one possible design, the first door body includes a first pivot and a first plate connected to the first pivot, and the second door body includes a second pivot and a second plate connected to the second pivot, with at least one end of both the first pivot and the second pivot pivot pivotally connected to the inner wall of the box.

[0012] In one possible design, at least one end of the first rotating shaft is fitted with a first elastic reset member, and the two ends of the first elastic reset member abut against the first plate and the box respectively.

[0013] At least one end of the second rotating shaft is fitted with a second elastic reset member, and the two ends of the second elastic reset member abut against the second plate and the box respectively.

[0014] In one possible design, a first sealing edge is provided on the second side of the first plate, and a second sealing edge is provided on the second side of the second plate. When the first and second doors are in the closed position, the first sealing edge and the second sealing edge are mated to seal the first through hole.

[0015] In one possible design, the surface of the first plate near the first through hole is provided with a first protrusion, and the surface of the second plate near the first through hole is provided with a second protrusion. The surface of the second protrusion facing away from the second plate is inclined, and the height of the second protrusion decreases linearly in the direction away from the first plate. The height of the first protrusion is the same as the height of the second protrusion.

[0016] In one possible design, the box body includes an upper half box and a lower half box, which are spliced ​​together to form a cavity. The upper half box has a snap-fit ​​protrusion and / or a snap-fit ​​groove on the side near the lower half box, and the lower half box has a snap-fit ​​groove and / or a snap-fit ​​protrusion on the side near the upper half box. The snap-fit ​​protrusion can engage with the snap-fit ​​groove for snap-fit.

[0017] The side wall of the box is equipped with a water outlet.

[0018] In one possible design, the housing is provided with mounting through holes for a guide pin, which is used to movably mount the housing to the manifold.

[0019] The first and second rotating shafts have clearance portions at their ends near the guide pin, which are used to prevent the first and second door bodies from interfering with the guide pin.

[0020] In one possible design, the clearance groove is an arched structure.

[0021] The second aspect of this application also provides a liquid-cooled cabinet, including a water manifold equipped with the anti-splash device provided in the first aspect of this application.

[0022] Compared with the prior art, the splash-proof device provided in this application has at least the following beneficial effects:

[0023] With the aforementioned anti-splash device, when the first and second connectors need to be connected, the second through hole of the box is first aligned with the second connector, the first connector is aligned with the first through hole and inserted, and then the first connector is inserted into the first through hole. The first connector will resist the door to rotate, switching it from the closed position to the open position. When the door is in the open position, the second connector is inserted. During the insertion process, due to the compact internal structure and limited space of the anti-splash device, the end of the second connector near the first connector will just pass through the avoidance groove provided on the surface of the door. This avoidance groove is provided on the surface of the door near the first through hole, and when in the open position, it will be located on the side of the inserted second connector. The avoidance groove provides more space for the second connector to facilitate its connection with the first connector, effectively preventing the second connector from colliding with the door when connecting with the first connector. In summary, applying the anti-splash box provided in this application to a water distributor can effectively solve the problem in the prior art where the second connector is prone to colliding with the door when it is in the open position.

[0024] The liquid-cooled cabinet provided in this application includes the aforementioned anti-splash device, and therefore also has the aforementioned technical effects. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0039] The purpose of this invention is to provide an anti-splash device that can effectively solve the technical problem in the prior art where the manifold connector collides with the door during the docking process with the server connector.

[0040] To achieve the above objectives, the present invention provides the following technical solution:

[0041] Please see Figures 1 to 7 This embodiment provides a splash-proof device, including: a box body 100 and a door body 200.

[0042] The housing 100 has an internal cavity. The housing 100 includes a first through hole 110 on its first end face for inserting a first connector, and a second through hole 120 on its second end face for inserting a second connector, both communicating with the cavity. The first connector can be a server connector, and the second connector can be a water manifold connector. Both are inserted into the cavity within the housing 100. This ensures that any splashed liquid during connection or separation is confined within the cavity of the housing 100, preventing it from spraying onto other equipment and affecting its normal operation. It is understood that the first and second end faces of the housing 100 are opposite to each other.

[0043] The door 200 is rotatably mounted on the inner wall of the first end face of the box 100, that is, the door 200 is disposed against the inner wall where the first end face of the box 100 is located; in this embodiment, the door 200 has a closed position that seals the first through hole 110 and an open position that opens the first through hole 110; the closed position is as follows: Figure 4 As shown, the door body 200 is entirely abutted against the first through hole 110, thereby effectively ensuring that the door body 200 completely closes the first through hole 110; the opening position is as follows. Figure 5 As shown, the door 200 is rotated 90 degrees toward the second through hole 120, so that the first through hole 110 is fully exposed. This can effectively ensure that the first connector is smoothly inserted into the box 100 to wait for the docking of the second connector.

[0044] It should be noted that a clearance groove 210 is provided on the surface of the door body 200 near the first through hole 110. The clearance groove 210 is used to make way for the second connector inserted into the second through hole 120 when the door body 200 is in the open position, so as to prevent the second connector from colliding with the door body 200.

[0045] Understandably, when the door 200 rotates towards the second through hole 120 to open the first through hole 110, the entire door 200 will be located inside the cavity of the box 100. Thus, when the second connector is inserted, it will first pass through the door 200 and then mate with the first connector. To prevent the second connector from colliding with the door 200 during its movement towards the first connector, a clearance groove 210 is provided on the surface of the door 200 near the first through hole 110. The clearance groove 210 provides some space for the second connector within the narrow space of the box 100, allowing it to mate smoothly with the first connector. Of course, the shape of the clearance groove 210 can be set according to actual conditions, as long as it does not affect the opening and closing of the door 200 and serves to provide clearance during the mating process of the first and second connectors.

[0046] With the aforementioned anti-splash device, when the first connector and the second connector need to be connected, the second through hole 120 of the housing 100 is first aligned with the second connector, and the first connector is aligned with the first through hole 110 and inserted. Then, the first connector is inserted into the first through hole 110, and the first connector will abut against the door 200 to rotate, switching it from the closed position to the open position. When the door 200 is in the open position, the second connector is inserted. During the insertion process, due to the compact internal structure and limited space of the anti-splash device, the end of the second connector near the first connector will just pass through the avoidance groove 210 provided on the surface of the door 200. The avoidance groove 210 is provided on the surface of the door 200 near the first through hole 110. When it is in the open position, it will be located on the side of the inserted second connector. The avoidance groove 210 can provide more space for the second connector to facilitate its connection with the first connector, effectively preventing the second connector from colliding with the door 200 when it is connected with the first connector. In summary, applying the anti-spray box provided in this application to the water distributor can effectively solve the problem in the prior art where the second connector is prone to collision with the door 200 when it is in the open position.

[0047] In one embodiment, the door 200 includes a first door 220 and a second door 230. A first side of the first door 220 is rotatably disposed on one side of the first through hole 110, and a first side of the second door 230 is rotatably disposed on the other side of the first through hole 110. When the second side of the first door 220 and the second side of the second door 230 are in the closed position, they are engaged to seal the first through hole 110.

[0048] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the door body 200 includes a first door body 220 and a second door body 230 that can rotate towards or away from each other. The first side of the first door body 220 is located on one side of the first through hole 110, and the second side is located in the middle of the first through hole 110. The second door body 230 is similar, with its first side located on the side of the first through hole 110 away from the first door body 220, and its second side also located in the middle of the first through hole 110. The second sides of the first door body 220 and the second door body 230 can be joined together when they are in the closed position to seal the first through hole 110. That is, the overall length of the first door body 220 and the second door body 230 when they are in the closed position is greater than the diameter of the first through hole 110. Thus, when the first door body 220 and the second door body 230 are in the closed position, they cooperate with the first end face of the box body 100 to seal the first through hole 110, thereby blocking the liquid sprayed from the second connector, i.e., preventing liquid spray from the second connector.

[0049] Furthermore, the first door body 220 includes a first pivot 221 and a first plate 222 connected to the first pivot 221, and the second door body 230 includes a second pivot 231 and a second plate 232 connected to the second pivot 231. At least one end of the first pivot 221 and the second pivot 231 are pivotally connected to the inner wall of the box body 100.

[0050] Specifically, such as Figure 6 and Figure 7 As shown, the first door body 220 and the second door body 230 have similar structures. The first door body 220 includes a first rotating shaft 221 for its own rotation and a first plate 222 for closing the first through hole 110. Similarly, the second door body 230 is the same, including a first rotating shaft 221 for its own rotation and a second plate 232 for closing the first through hole 110. The first plate 222 and the second plate 232 have the same shape and size. That is, the first door body 220 and the second door body 230 are symmetrically arranged with respect to the first through hole 110.

[0051] It should be noted that when the first pivot 221 and the second pivot 231 are installed on the inner wall of the box 100, since the first plate 222 and the second plate 232 are relatively light, it is sufficient for only one end to be pivotally connected to the inner wall of the box 100. Of course, in order to ensure the stability of the rotational connection between the first door 220 and the second door 230, both ends can be pivotally connected to the inner wall of the box 100.

[0052] Furthermore, at least one end of the first rotating shaft 221 is fitted with a first elastic reset member 223, and the two ends of the first elastic reset member 223 abut against the first plate 222 and the box 100 respectively; at least one end of the second rotating shaft 231 is fitted with a second elastic reset member 233, and the two ends of the second elastic reset member 233 abut against the second plate 232 and the box 100 respectively.

[0053] Understandably, in order to enable the first door 220 and the second door 230 to automatically switch from the open position to the closed position when the first connector inside the box 100 is pulled out, a first elastic reset member 223 and a second elastic reset member 233 are respectively provided at the ends of the first rotating shaft 221 and the second rotating shaft 231. Since the first plate 222 and the second plate 232 are small in size and light in weight, in order to save space inside the box 100, the first elastic reset member 223 and the second elastic reset member 233 can be installed only at one end of the first rotating shaft 221 and the second elastic reset member 233. Alternatively, to ensure the stability of the first door 220 and the second door 230 when closed, the first elastic reset member 223 can be installed at both ends of the first rotating shaft 221, and the second elastic reset member 233 can be installed at both ends of the second rotating shaft 231. Furthermore, in this embodiment, the first elastic reset member 223 and the second elastic reset member 233 can specifically be torsion springs.

[0054] Specifically, such as Figure 2 As shown, a first elastic reset member 223 can be fitted at both ends of the first rotating shaft 221, or at one end. One end of the first elastic reset member 223 will abut against the inner wall of the box 100, and the other end will engage with the first plate 222. The first elastic reset member 223 will always have a tendency to make the first door 220 return from the open position to the closed position, that is, it will always have a tendency to make the first plate 222 rotate around the first rotating shaft 221 toward the first through hole 110. Similarly, a second elastic reset member 223 can be fitted at both ends of the second rotating shaft 231. The reset member 233, or one end of which is fitted with a second elastic reset member 233, will also abut against the inner wall of the box 100 at one end, and the other end will be engaged with the second plate 232. The second elastic reset member 233 will always have the tendency to make the second door 230 return from the open position to the closed position, that is, it will always have the tendency to make the second plate 232 rotate around the second pivot 231 toward the first through hole 110. It should be noted that the first plate 222 and the second plate 232 can be connected in the closed position to seal the water distribution end connector.

[0055] In one embodiment, a first sealing edge is provided on the second side of the first plate 222, and a second sealing edge is provided on the second side of the second plate 232. When the first door 220 and the second door 230 are in the closed position, the first sealing edge and the second sealing edge are connected to seal the first through hole 110.

[0056] To enhance the sealing of the first through hole 110 by the first door body 220 and the second door body 230 when they are in the closed position, a first sealing edge and a second sealing edge that can be mated are respectively provided on the second side of the first plate body 222 and the second plate body 232. Both the first sealing edge and the second sealing edge are stepped structures. In the closed position, the second sealing edge is located outside the first sealing edge.

[0057] Furthermore, the surface of the first plate 222 near the first through hole 110 is provided with a first protrusion 224, and the surface of the second plate 232 near the first through hole 110 is provided with a second protrusion 234. The surface of the second protrusion 234 away from the second plate 232 is an inclined surface, and the height of the second protrusion 234 decreases linearly in the direction away from the first door 220. The height of the first protrusion 224 is the same as the height of the second protrusion 234.

[0058] As shown in the figure, in order to make it easier for the first connector to force the first door body 220 and the second door body 230 to rotate toward the second through hole 120, a first protrusion 224 and a second protrusion 234 are respectively provided on the surfaces of the first door body 220 and the second door body 230 near the first through hole 110. It should be noted that the first protrusion 224 and the second protrusion 234 have different shapes. The thickness of the first protrusion 224 remains constant, while the thickness of the second protrusion 234 gradually decreases in the direction away from the first door body 220. In this way, when the first connector is inserted into the second through hole 120... During the insertion of the first connector 110, it will first contact the first protrusion 224. As the first connector continues to be inserted, the first door 220 will rotate first. Then the first connector will contact the second protrusion 234. As the manifold connector continues to be inserted, the second door 230 will also start to rotate. This can avoid the first door 220 and the second door 230 rotating at the same time, causing the first sealing edge and the second sealing edge to rub against each other and cause poor engagement, which would affect the sealing effect later. Moreover, after the first connector is fully inserted, it can ensure that the first door 220 and the second door 230 are both in the open position.

[0059] In one embodiment, the box body 100 includes an upper half box 130 and a lower half box 140, which are joined together to form a cavity. The upper half box 130 is provided with a snap-fit ​​protrusion 150 and / or a snap-fit ​​groove 160 on the side near the lower half box 140, and the lower half box 140 is provided with a snap-fit ​​groove 160 and / or a snap-fit ​​protrusion 150 on the side near the upper half box 130. The snap-fit ​​protrusion 150 can engage with the snap-fit ​​groove 160. The side wall of the box body 100 is provided with a water outlet 180.

[0060] Understandably, to improve the assembly efficiency of the splash guard, the box 100 can be divided into two parts: an upper half 130 and a lower half 140. These two parts can be joined together to form a complete box 100, as detailed below. Figure 2 As shown; furthermore, snap-fit ​​protrusions 150 and / or snap-fit ​​grooves 160 can be provided at the mating edge of the upper half box 130. Correspondingly, snap-fit ​​grooves 160 and / or snap-fit ​​protrusions 150 that can cooperate with them need to be provided at the mating edge of the lower half box 140. The number and setting method of snap-fit ​​grooves 160 and snap-fit ​​protrusions 150 can be adjusted appropriately according to actual needs, but it is necessary to ensure that the upper half box 130 and the lower half box 140 can be stably connected.

[0061] It should be noted that the upper half box 130 and the lower half box 140 are assembled by snap-fit, but the assembly method of the upper half box 130 and the lower half box 140 is not limited to snap-fit.

[0062] In addition, to prevent excessive water from entering the housing 100, a water outlet 180 can be installed on one side of the housing 100. Liquid splashed into the housing 100 can be drained into the corresponding water receiving tank through the water outlet 180, and finally discharged through the external water receiving pipe and water receiving tray, effectively preventing excessive liquid from entering the cabinet. The water outlet 180 can also be formed by assembling the upper half of the housing 130 and the lower half of the housing 140.

[0063] In one embodiment, the housing 100 is provided with a mounting through hole 170 for a guide pin to pass through, the guide pin being used to movably mount the housing 100 to the manifold.

[0064] Specifically, such as Figures 1 to 5 As shown, a through hole 170 is provided at a diagonal position of the box 100, penetrating the entire box 100. The through hole 170 allows the anti-splash device to be installed on the guide pin of the manifold. This provides a certain guiding effect to the box 100 and also serves a fixing function. That is, the anti-splash device can be firmly fixed to the manifold through the guide pin, ensuring that the first connector can be blindly inserted into the first through hole 110 and accurately connected to the second connector. Specifically, when the first connector needs to be connected to the second connector, the first connector is first inserted into the first through hole 110, which will abut against the door 200, causing it to switch from the closed position to the open position. At the same time, it will press the box 100 to move along the guide pin toward the second connector, so that the second connector can be smoothly inserted into the second through hole 120 and then accurately connected to the first connector.

[0065] In addition, in order to ensure that the box 100 can automatically move away from the second connector after the first connector and the second connector are separated, thereby ensuring that the second connector is disengaged from the second through hole 120, a spring can be sleeved on the outer periphery of the guide pin, and the spring is located between the box 100 and the water manifold, so that the box 100 always has elastic restoring force.

[0066] Furthermore, the first pivot 221 and the second pivot 231 are provided with a clearance portion 240 at the end near the guide pin. The clearance portion 240 is used to prevent the first door body 220 and the second door body 230 from interfering with the guide pin.

[0067] Understandably, in order to prevent the first door body 220 and the second door body 230 from interfering with the guide pin when they rotate, a partial cut can be made at the end of the first rotating shaft 221 and the second rotating shaft 231 near the guide pin to create a clearance portion 240, as shown in the following figure. Figure 6 and Figure 7 As shown, this setup avoids interference with the guide pins in confined spaces.

[0068] In one embodiment, the clearance groove 210 has an arched structure.

[0069] Understandably, the clearance groove 210 is designed to allow the passage of the second connector when the door 200 is in the open position. Therefore, to maximize the use of the space in the box 100, the clearance groove 210 is designed as an arched structure, i.e., an arc-shaped groove, that matches the shape of the end of the second connector. Specifically, as shown... Figure 6 and Figure 7 As shown.

[0070] Based on the anti-splash device provided in the above embodiments, this application provides a liquid-cooled cabinet, including a water manifold equipped with the above-mentioned anti-splash device. Therefore, the liquid-cooled cabinet also has the above-mentioned technical effects.

[0071] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0072] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0073] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
