[0044] Through the above-mentioned drawings, the clear embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0045] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] As shown in the background art, in the prior art, the liquid leakage detection line is fixed to the coolant delivery pipe by acetic acid tape. When the coolant leaks, the coolant conducts the liquid leakage detection line, so that the liquid leakage detection line can timely send a liquid leakage signal to the control module in the electronic device. However, fixing the liquid leakage detection line by tape requires a large amount of manpower and time, resulting in a low assembly efficiency of the liquid leakage detection device. In addition, when the coolant leaks out of the delivery pipe, the leaked coolant may drip onto electronic components such as circuit boards in the electronic device, causing damage to the electronic device.

[0047] To solve the above technical problems, an embodiment of the present application provides a liquid leakage detection device, a refrigeration system and an electronic device. The liquid leakage detection device includes a delivery pipe, a liquid leakage detection line and a sleeve. The delivery pipe is connected to a coolant supply device to deliver coolant. The liquid leakage detection line is arranged on the side of the delivery pipe to detect whether the delivery pipe leaks. The sleeve is sleeved outside the delivery pipe and the liquid leakage detection line to fix the liquid leakage detection line. The liquid leakage detection device delivers coolant through the delivery pipe. The liquid leakage detection line is fixed to the side of the delivery pipe by the sleeve to detect whether the delivery pipe leaks. When the coolant leaks out of the delivery pipe, the coolant flows to the liquid leakage detection line, making the liquid leakage detection line conductive so as to send a liquid leakage signal in time, so as to stop delivering coolant in time and repair the delivery pipe. In this way, compared with the prior art of fixing the liquid leakage detection line to the delivery pipe by tape, fixing by the sleeve has a more stable structure. And when assembling the liquid leakage detection device, only need to insert the delivery pipe and the liquid leakage detection line into the sleeve at the same time to complete the assembly, the operation is simple and convenient, which is beneficial to saving the manpower and time required for fixing the liquid leakage detection line and improving the assembly efficiency of the liquid leakage detection device.

[0048] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings:

[0049] It should be noted that the liquid leakage detection device provided by the embodiment of the present application can be applied to various different refrigeration systems.

[0050] See Figure 1 、Figure 7 and Figure 9 As shown in Figure 9 , the liquid leakage detection device 100 for a refrigeration system according to an embodiment of the present application includes a delivery pipe 110, a liquid leakage detection line 120, and a sleeve 130. Among them, the delivery pipe 110 is used to be connected to a coolant supply device to deliver coolant. Figure 1 The direction indicated by the arrow in Figure 1 is the flow direction of the coolant in the delivery pipe 110; the liquid leakage detection line 120 is used to detect whether the coolant in the delivery pipe 110 leaks; the sleeve 130 is sleeved on at least part of the delivery pipe 110 and the liquid leakage detection line 120, so that the liquid leakage detection line 120 is fixed to the side of the delivery pipe 110.

[0051] In the present application, the liquid leakage detection device 100 delivers coolant by setting the delivery pipe 110. The liquid leakage detection line 120 is fixed to the side of the delivery pipe 110 through the sleeve 130 to detect whether the delivery pipe 110 leaks. When the coolant leaks from the delivery pipe 110, the coolant flows onto the liquid leakage detection line 120, making the liquid leakage detection line 120 conductive so as to emit a liquid leakage signal, so as to stop delivering coolant in time and repair the delivery pipe 110. At the same time, the liquid leakage detection line 120 can be arranged below the delivery pipe 110, so that when any part of the delivery pipe 110 is damaged and leaks, the coolant can flow to the liquid leakage detection line 120 under the action of gravity, so as to ensure that the liquid leakage detection line 120 can detect the liquid leakage of any part of the delivery pipe 110 and avoid omission.

[0052] It can be understood that since the delivery pipe 110 needs to be connected to devices such as cold plates in the refrigeration system, the delivery pipe 110 may be arranged in multiple sections. In order to ensure the connectivity of the circuit, the liquid leakage detection line 120 is a whole. Therefore, the sleeve 130 only needs to be correspondingly arranged in multiple sections with the delivery pipe 110. Compared with the prior art, fixing the liquid leakage detection line 120 on the delivery pipe 110 with tape requires a large amount of manpower and time. By fixing with the sleeve 130, when assembling the liquid leakage detection device 100, only the delivery pipe 110 and the liquid leakage detection line 120 need to be inserted into the sleeve 130 at the same time to complete the assembly, and the operation is simple and convenient, which is beneficial to improving the assembly efficiency of the liquid leakage detection device 100.

[0053] In addition, since the casing 130 has a uniform shape, fixing the liquid leakage detection line 120 through the casing 130 can ensure that the distances between the liquid leakage detection line 120 and various parts of the delivery pipe 110 are consistent, which is beneficial to improving the structural stability and ensuring that the liquid leakage detection line 120 can accurately detect liquid leakage. At the same time, the casing 130 can be made of thermoplastic elastomer, polyurethane, thermoplastic polyurethane, polyvinyl chloride, silicone, etc. The embodiments of the present application do not limit this, as long as a flexible, waterproof and insulating material is selected, so that the casing 130 can change its shape according to the pipeline of the delivery pipe 110. Since the casing 130 has waterproofness, when the coolant in the delivery pipe 110 leaks out, while the liquid leakage detection line 120 emits a liquid leakage signal, the casing 130 can receive the leaked coolant, preventing the coolant from dripping onto devices such as circuit boards inside the electronic device, which is beneficial to further ensuring the safety of the electronic device and preventing it from being damaged.

[0054] In some realizable ways, referring to Figure 1 、 Figure 7 and Figure 9 as shown, the casing 130 of the embodiment of the present application defines an accommodation space, and the accommodation space includes a first accommodation cavity 131 and a second accommodation cavity 132 that communicate with each other; both the first accommodation cavity 131 and the second accommodation cavity 132 extend along the axial direction of the casing 130, and the first accommodation cavity 131 and the second accommodation cavity 132 are distributed along the radial direction of the casing 130. The delivery pipe 110 is located in the first accommodation cavity 131, and the liquid leakage detection line 120 is located in the second accommodation cavity 132.

[0055] In some embodiments, the cross-section of the casing 130 along the radial direction is in the shape of an "8", that is, the cross-sections of the first accommodation cavity 131 and the second accommodation cavity 132 are circular corresponding to the shapes of the delivery pipe 110 and the liquid leakage detection line 120. In this way, when assembling the liquid leakage detection device 100, it is only necessary to insert the delivery pipe 110 and the liquid leakage detection line 120 into the first accommodation cavity 131 and the second accommodation cavity 132 of the casing 130 respectively, which is simple to operate and beneficial to improving the assembly efficiency of the liquid leakage detection device 100. At the same time, the first accommodation cavity 131 and the second accommodation cavity 132 are distributed and communicate along the radial direction. When the coolant in the delivery pipe 110 leaks out, the coolant flows from the first accommodation cavity 131 into the second accommodation cavity 132 and then contacts the liquid leakage detection line 120, so that the liquid leakage detection line 120 can emit a liquid leakage signal to remind the staff to perform maintenance in time. Therefore, the casing 130 can also play a role in guiding the flow path of the coolant to ensure that the leaked coolant can contact the liquid leakage detection line 120.

[0056] In some realizable ways, referring to Figure 1 、 Figure 7 and Figure 9 as shown, there is a gap between the liquid leakage detection line 120 of the embodiment of the present application and the inner wall of the second accommodation cavity 132.

[0057] It is understandable that the inner diameter of the second accommodating cavity 132 is set to be larger than the diameter of the liquid leakage detection line 120. When assembling the liquid leakage detection line 120, the liquid leakage detection line 120 can be inserted into the sleeve 130 more quickly, reducing the resistance generated by the friction between the sleeve 130 and the liquid leakage detection line 120, improving the assembly efficiency of the liquid leakage detection line 120. At the same time, it can also reserve a certain storage space for the leaked coolant, preventing the coolant from directly overflowing from the sleeve 130 after leakage and damaging the electronic device, which is beneficial to protecting the electronic device from damage.

[0058] In some realizable ways, referring to Figure 1 、 Figure 2 and Figure 7 As shown, the embodiment of the present application further includes a valve assembly 140; the valve assembly 140 is connected to the delivery pipe 110, and the valve assembly 140 is electrically connected to the liquid leakage detection line 120; the valve assembly 140 is configured to block the delivery pipe 110 and the coolant supply device when the liquid leakage detection line 120 detects the leakage of the coolant in the delivery pipe 110.

[0059] In specific implementation, the valve assembly 140 can control the delivery pipe 110 to be blocked or conducted. When the electronic device is operating normally, the delivery pipe 110 remains conducted to ensure the normal circulation of the coolant in the refrigeration system for heat dissipation. When the coolant in the delivery pipe 110 leaks, the liquid leakage detection line 120 sends a liquid leakage signal to the valve assembly 140, and the valve assembly 140 blocks the delivery pipe 110 and the coolant supply device, preventing the coolant from continuing to flow into the delivery pipe 110 and avoiding more coolant leakage, providing time for the staff to repair and replace the delivery pipe 110.

[0060] In some realizable ways, referring to Figures 1 to 4 and Figure 7 As shown, the valve assembly 140 of the embodiment of the present application includes a control module and a solenoid valve 141; the control module is electrically connected to both the solenoid valve 141 and the liquid leakage detection line 120; the delivery pipe 110 includes an input section 111, a connection section 112, and an output section 113 that are connected in sequence, and both the input section 111 and the output section 113 are connected to the coolant supply device; both ends of the solenoid valve 141 are connected to the input section 111 and the connection section 112 respectively. When the liquid leakage detection line 120 detects the leakage of the coolant in the delivery pipe 110, the control module controls the solenoid valve 141 to close to block the delivery pipe 110.

[0061] It should be noted that the solenoid valve 141 is provided at the connection between the input section 111 and the output section 113, which can block or conduct the delivery pipe 110. The solenoid valve 141 has a valve body 1411 and a flow-through pipeline 1412 inside. The flow-through pipeline 1412 is connected to both the input section 111 and the output section 113. When the control module receives a liquid leakage signal, the control module controls the solenoid valve 141 to make the valve body 1411 fall to block the flow-through pipeline 1412, thereby preventing the coolant in the coolant supply device from further entering the connection section 112, which is beneficial to reducing liquid leakage. In addition, a solenoid valve 141 can be provided between the output section 113 and the connection section 112. When the two solenoid valves 141 work simultaneously, it can prevent the coolant from flowing backward and further reduce liquid leakage.

[0062] Meanwhile, after receiving the liquid leakage signal, the control module can also timely send out an alarm signal. For example, it controls the warning light to turn on and the buzzer to emit a beeping sound, etc., to remind the staff of the liquid leakage phenomenon, and timely repair the delivery pipe 110 to avoid further expansion of losses.

[0063] In some implementable ways, as shown in Figures 1 to 7 the valve assembly 140 of the embodiment of the present application further includes a check valve 142; both ends of the check valve 142 are respectively connected to the output section 113 and the connection section 112, and the check valve 142 is configured to block the delivery pipe 110 when the coolant flows from the output section 113 to the connection section 112.

[0064] In some embodiments, a check valve 142 is provided between the output section 113 and the connection section 112. When the solenoid valve 141 is conducting, the coolant in the delivery pipe 110 flows from the connection section 112 to the output section 113. At this time, the check valve 142 is conducting. When the solenoid valve 141 is closed, no new coolant flows into the connection section 112. As the coolant flows out, the hydraulic pressure in the coolant supply device is greater than the hydraulic pressure in the delivery pipe 110, which may cause the coolant to flow backward, that is, from the output section 113 to the connection section 112. At this time, the check valve 142 blocks the delivery pipe 110, which can prevent the coolant from flowing backward into the connection section 112, thereby ensuring that no new coolant flows into the connection section 112 and facilitating the repair of the delivery pipe 110.

[0065] In addition, compared with setting another solenoid valve 141 between the output section 113 and the connection section 112 and having the two solenoid valves 141 work simultaneously, in the embodiment of the present application, one check valve 142 is provided in cooperation with one solenoid valve 141. The check valve 142 occupies less space, has a simple structure, and lower cost, which is beneficial to reducing the production cost of the liquid leakage detection device 100 and saving the space inside the electronic device.

[0066] In some implementable ways, as shown in Figures 1 to 7As shown in the figure, the check valve 142 of the embodiment of the present application includes a housing 1421, an elastic member 1422, and a stopper 1423; the housing 1421 defines a flow channel, and the flow channel includes an inlet section 1421a and an outlet section 1421b that are sequentially connected. The inlet section 1421a is connected to the connection section 112, and the outlet section 1421b is connected to the output section 113; one end of the elastic member 1422 is fixedly connected to the housing 1421, the other end of the elastic member 1422 is connected to the stopper 1423, and the stopper 1423 is slidably connected to the housing 1421 along the extension direction of the flow channel.

[0067] In a specific implementation, when the solenoid valve 141 is turned on, as Figure 5 shown, the hydraulic pressure in the inlet section 1421a is greater than the hydraulic pressure in the outlet section 1421b. The dotted line direction in the figure is the flow direction of the coolant. The coolant flows from the inlet section 1421a to the outlet section 1421b, and the stopper 1423 slides away from the inlet section 1421a, and the elastic member 1422 is compressed to connect the inlet section 1421a and the outlet section 1421b; when the solenoid valve 141 is closed, as Figure 6 shown, the hydraulic pressure in the inlet section 1421a is lower than the hydraulic pressure in the outlet section 1421b. The dotted line direction in the figure is the flow direction of the coolant. The coolant flows from the outlet section 1421b to the inlet section 1421a, and the elastic member 1422 pushes the stopper 1423 to slide toward the inlet section 1421a to block the inlet section 1421a with the stopper 1423 to prevent the coolant from flowing backward.

[0068] In some implementable ways, referring to Figures 1 to 7 shown, the refrigeration system of the embodiment of the present application includes at least a first cold plate 10 and a second cold plate 20. Among them, the specific number of cold plates is not limited in the embodiment of the present application and can be set according to the layout of electronic components inside the electronic device; the connection section 112 includes at least a first connection section 1121, a second connection section 1122, and a third connection section 1123 corresponding to the number of cold plates; both ends of the first connection section 1121 are respectively connected to the solenoid valve 141 and the first cold plate 10, both ends of the second connection section 1122 are respectively connected to the first cold plate 10 and the second cold plate 20, and both ends of the third connection section 1123 are respectively connected to the second cold plate 20 and the check valve 142.

[0069] In this way, while ensuring that both the first cold plate 10 and the second cold plate 20 can be filled with coolant, the on or off of the entire delivery pipe 110 can be controlled only by one solenoid valve 141 and one check valve 142, with a simple structure, which is beneficial to saving space and cost.

[0070] In some implementable ways, referring to Figures 1 to 7As shown, a connection structure 150 is provided at the end of at least one of the input section 111, the first connection section 1121, the second connection section 1122, the third connection section 1123, and the output section 113 of the embodiment of the present application.

[0071] It can be understood that connection structures 150 need to be provided between the input section 111 and the coolant supply device and the solenoid valve 141, between the first connection section 1121 and the solenoid valve 141 and the first cold plate 10, between the second connection section 1122 and the first cold plate 10 and the second cold plate 20, between the third connection section 1123 and the second cold plate 20 and the check valve 142, and between the output section 113 and the check valve 142 and the coolant supply device to ensure stable connection everywhere and prevent coolant from leaking out at the connections. In specific implementation, the connection structures 150 at each location can be set to the same structure to improve production efficiency, or can be flexibly set to different structures according to actual needs. The embodiment of the present application does not limit this.

[0072] In some realizable ways, referring to Figures 1 to 9 As shown, the connection structure 150 of the embodiment of the present application includes a nut 151 and a first joint 152; the nut 151 is partially sleeved on the conveying pipe 110, the first joint 152 passes through the nut 151 and is inserted into the conveying pipe 110, and the first joint 152 is bolted to the nut 151, and the sleeve 130 is in interference fit with the nut 151.

[0073] In specific implementation, the first joint 152 can be integrally provided with the solenoid valve 141, the coolant supply device, the first cold plate 10 or the second cold plate 20. At least part of the outer wall of the first joint 152 is provided with a thread matching the inner wall of the nut 151. The nut 151 is fixed on the conveying pipe 110, and the first joint 152 is inserted into the conveying pipe 110 and fixed by being bolted to the nut 151. Figure 7 It can be seen that since the nut 151 is sleeved on the conveying pipe 110, the end of the sleeve 130 can be in interference fit with the nut 151. Since the sleeve 130 is made of a flexible material, when the coolant leaks out and fills the accommodation space in the sleeve 130, the coolant can be extruded from the end of the sleeve 130. In this way, when more coolant leaks, the coolant can flow out concentratedly from the end of the sleeve 130, and only a liquid collecting device needs to be provided at the end of the sleeve 130, thus effectively preventing the overflowing coolant from dripping on the electronic components inside the electronic device and protecting the safety of the electronic device.

[0074] In some realizable ways, referring to Figures 1 to 5 、 Figure 10 and Figure 11As shown, the connection structure 150 of the embodiment of the present application includes a fastener 153 and a second joint 154; the second joint 154 is partially inserted into the delivery pipe 110, and the fastener 153 is sleeved outside the delivery pipe 110 to fix the second joint 154 and the delivery pipe 110.

[0075] In some embodiments, the fastener 153 may be an annular structure with an adjustable inner diameter. A tower-shaped clamping structure may be provided on the outer wall of the second joint 154, and a clamping and mating structure that mates with it may be provided on the inner wall of the delivery pipe 110. After the second joint 154 is inserted into the delivery pipe 110 and the clamping structure is clamped and mated with the clamping and mating structure, the fastener 153 further tightens the delivery pipe 110 to ensure the stability of the connection between the delivery pipe 110 and the second joint 154. The second joint 154 may be integrally provided with the solenoid valve 141, the check valve 142, etc. Exemplarily, as Figure 4 and Figure 5 shown, the second joint 154 is provided at the flow-through pipeline 1412 of the solenoid valve 141, the inlet section 1421a and the outlet section 1421b of the check valve 142.

[0076] In some implementable ways, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 shown, the embodiment of the present application further includes a liquid collecting structure 160. The liquid collecting structure 160 is provided below the connection structure 150.

[0077] It should be noted that the liquid collecting structure 160 may be a liquid collecting tank, a liquid collecting tray or other structures, which are not limited in the embodiment of the present application, as long as it can hold the coolant overflowing from the connection structure 150.

[0078] Referring to Figure 1 shown, the embodiment of the present application further provides a refrigeration system for an electronic device, including any one of the above-mentioned liquid leakage detection devices 100 for a refrigeration system.

[0079] Among them, the structure and working principle of the liquid leakage detection device 100 have been described in detail in the above embodiments, and will not be elaborated here one by one.

[0080] In the embodiment of the present application, by setting a refrigeration system inside the electronic device, heat can be dissipated in time, thereby ensuring the safe and stable operation of the electronic device.

[0082] In the embodiment of the present application, the refrigeration system is arranged on the server 1 of the electronic device to ensure that the server 1 works within a suitable temperature, which is conducive to ensuring the safe, efficient and stable operation of the electronic device. Among them, the control unit on the server 1 can be formed as a control module of the leakage detection device 100.

[0083] In summary, the embodiment of the present application provides a leakage detection device 100, a refrigeration system and a control module, wherein the leakage detection device 100 includes a delivery pipe 110, a leakage detection line 120 and a sleeve 130, and the leakage detection line 120 and the delivery pipe 110 are fixed together by the sleeve 130, and the structure is stable and conducive to improving the assembly efficiency of the leakage detection line 120, saving manpower and time. During specific operation, when the coolant in the delivery pipe 110 leaks out, the coolant contacts the leakage detection line 120, and the leakage detection line 120 sends a leakage signal to the control module, and the control module sends an alarm signal and controls the solenoid valve 141 to close, and the one-way valve 142 is closed accordingly, thereby preventing the coolant from continuing to be delivered, and the coolant overflows from the end of the sleeve 130 and is collected by the liquid collecting structure 160. At the same time, the staff promptly inspects and replaces the delivery pipe 110 to avoid further damage to the electronic equipment.
