Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and more specifically to a server, a liquid cooling system and a liquid leakage protection device thereof. Background Art

[0002] As the power density of servers increases, higher requirements are placed on heat dissipation. Liquid cooling heat exchange can provide higher heat exchange efficiency than air cooling heat exchange to meet the server heat exchange requirements. At present, the liquid cooling of servers is mainly cold plate liquid cooling. Cold plate liquid cooling is also called liquid cooling plate. The liquid cooling plate exchanges heat with high-heat generating components of the server, and then connects to the heat exchange device through the inlet and outlet liquid pipes to quickly transfer heat to the outside of the server.

[0003] During the operation of the server, the liquid cooling plate, the inlet and outlet pipes, or the welding parts between the liquid cooling plate and the inlet and outlet pipes may leak due to fatigue, vibration, etc. If the electronic components of the server come into contact with the leaked high-pressure liquid, short circuits and other faults may occur. Therefore, it is necessary to detect whether the liquid cooling heat dissipation module has leaks, and shut down the machine in time when a leak is detected. In order to extend the processing time, a liquid collection component can be set for the location where the liquid cooling system is prone to leaks, and connected to the pump body through a pipeline. When the pump body is started, the leaked liquid collected in the liquid collection component can be sucked away.

[0004] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0005] Corresponding to different leakage positions of the liquid cooling module, multiple liquid collecting components are usually set correspondingly, and the multiple liquid collecting components are respectively connected to the same pump body through pipelines, that is, the pump body is connected to multiple branches to achieve leakage suction. However, if some of the branches in the multiple branches leak at the corresponding positions, and some branches do not leak, the pump body will suck liquid and gas from the multiple branches at the same time when working, so the leakage is difficult to be effectively sucked away. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a server, a liquid cooling system and a leakage protection device thereof, the structural design of which can effectively solve the problem that leakage from multiple branches is difficult to be effectively sucked away simultaneously.

[0032] The embodiment of the utility model discloses a server, a liquid cooling system and a liquid leakage protection device thereof, which can control the on-off of a suction pipeline in a physical manner without manual operation or electric control switching, thereby improving the suction capacity.

[0033] 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.

[0034] The leakage protection device provided in the present application is applicable to, but not limited to, providing leakage collection and pumping functions for the liquid cooling and heat dissipation module of the server. When the liquid cooling and heat dissipation module leaks, the liquid will flow into the liquid collecting component along the drainage tube and the liquid collecting device, and the suction component will be started at the same time to suck away the leaked liquid in the liquid collecting component. Usually, multiple liquid collecting components are provided, and suction pipelines are provided respectively, and the ends of each suction pipeline are placed in the liquid collecting component. One suction device can be specifically provided, that is, a one-to-many method is adopted. When a suction device of the leakage protection device corresponds to multiple branches, a suction pipeline is connected to the corresponding liquid collecting component as a branch. In order to improve the suction effect, the inventor of the present application has found that valves can be provided in each branch, and each valve is controlled manually or by circuits so that some branches are connected and some branches are disconnected during suction. It can be understood that the connection here refers to the connection between the liquid collecting component and the suction device through the corresponding suction pipeline, and the disconnection refers to the suction pipeline disconnecting the connection between the liquid collecting component and the suction device. However, manually controlling valves inside the server will affect the timeliness of pumping out leaks, the circuit control cost is too high, and too many control units and lines will be introduced into the server, making the lines complicated and unsightly. And there is no good solution to the above technical problems for multi-branch pumping structures that are inconvenient to install valves or have high valve installation costs.

[0035] The leakage protection device provided in the present application is suitable for a single suction device corresponding to multiple branches, and controls the unblocking of the suction pipeline by physical means, so as to at least partially solve the defects such as the need to detect pipeline leakage when opening and closing the valve, which makes the cost high, the overall circuit is complicated and unsightly, and the pumping capacity is poor if the valve is not installed.

[0036] In one embodiment, see Figure 1-Figure 2 The liquid leakage protection device provided in the present application comprises a suction device, a liquid collecting component 1 and a suction pipeline 2. The suction device is a power device of the liquid leakage protection device, which is used to provide negative pressure to pump the leaked liquid collected in the liquid collecting component 1 to the outside of the storage device or the liquid cooling module through the suction pipeline 2.

[0037] The number of the liquid collecting components 1 and the suction pipeline 2 are both multiple, and multiple here means two or more. Multiple liquid collecting components 1 are respectively arranged at different positions of the liquid cooling heat dissipation module to collect leaked liquid at different positions of the liquid cooling heat dissipation module. The specific setting position of the liquid collecting component 1 can be set accordingly according to the position where the liquid cooling heat dissipation module is prone to leakage, such as being set at the liquid cooling plate 11 of the liquid cooling heat dissipation module, the liquid inlet and outlet pipes 12 connected to the liquid cooling plate 11, the connection between the liquid inlet and outlet pipes 12 and the liquid cooling plate 11, the manifold, etc.

[0038] A plurality of suction pipelines 2 are respectively arranged corresponding to each liquid collecting part 1. Specifically, at least one suction pipeline 2 is arranged corresponding to one liquid collecting part 1. The first end of each suction pipeline 2 is arranged in the corresponding liquid collecting part 1, and the second end is connected to the suction device. At least one suction pipeline 2 is provided with a blocking component 21 at the first end. The blocking component 21 is used to block the passage of gas and allow the leakage in the corresponding liquid collecting part 1 to pass through. It should be noted that the blocking component 21 in the present application can block the passage of gas by using its own physical or chemical properties, and can automatically allow the leakage collected in the liquid collecting part 1 to pass through, that is, the properties of the blocking component 21 meet the requirements of being able to block the passage of gas and allow the leakage in the corresponding liquid collecting part 1 to pass through. It can be understood that the properties here include the physical or chemical properties of the blocking component 21 itself, that is, the opening and closing of the suction pipeline 2 does not require the help of manual operation or electrical control. The blocking effect of the blocking component 21 on gas refers to the ability to block the passage of gas before the blocking component 21 encounters liquid, and whether it can block gas after encountering liquid is not limited.

[0039] The liquid leakage protection device provided by the present application is applied, by setting a plugging component 21 at the first end of the suction pipeline 2, the plugging component 21 can block the passage of gas, and then when no leaked liquid is collected in the liquid collecting component 1 corresponding to the suction pipeline 2 or the collected leaked liquid does not meet the suction requirement, the plugging component 21 closes the suction pipeline 2, so that when the suction device starts suction, the leaked liquid in the corresponding liquid collecting component 1 can be better sucked away through other suction pipelines 2. In addition, when leaked liquid is collected in the liquid collecting component 1 corresponding to the suction pipeline 2 or the collected leaked liquid meets the suction requirement, the plugging component 21 at the first end of the suction pipeline 2 can allow the leaked liquid to enter the suction pipeline 2 through the first end and be sucked away along the suction pipeline 2. In summary, the leakage protection device provided in the present application can meet the needs of collecting and pumping leakage from multiple branches. When one or more branches leak, the leaked liquid can be quickly pumped away, thereby improving the pumping efficiency and pumping capacity, thereby providing a longer operation time for emergency operations of liquid cooling module leakage.

[0040] In some embodiments, the blocking component 21 is a seal for sealing the first end, and the seal can release the seal when it contacts the leaking liquid in the corresponding liquid collecting component 1 to connect the corresponding liquid collecting component 1 with the suction device. In this embodiment, the blocking component 21 is a seal, and the blocking component 21 is disposable, that is, the seal can maintain its original state when it does not contact the leaking liquid, that is, it blocks the suction pipeline 2 to disconnect the connection between the liquid collecting component 1 and the suction device. When the seal contacts the leaking liquid, its state changes, thereby releasing the blocking effect on the first end to connect the liquid collecting component 1 with the suction device. While the state change of the seal is used to block the passage of gas, the leaking liquid is allowed to pass through when there is a leak, and the structure is simple and reliable.

[0041] In some embodiments, the material of the seal is a material that can be dissolved in the leaking liquid, that is, a material that dissolves when encountering a leaking liquid. Then, when encountering a leaking liquid, the suction pipeline 2 inside the liquid collecting component 1 without a leaking liquid is still blocked, and the seal on the suction pipeline 2 inside the liquid collecting component 1 with a leaking liquid will quickly dissolve, and the corresponding suction pipeline 2 will become a passage, and the suction device can quickly extract the leaking liquid in the liquid collecting component 1 to reduce the damage to the inside of the server caused by the leaking liquid. The seal is made of a material that is easily soluble in the leaking liquid, has a simple structure, low cost, and is easy to assemble with the suction pipeline 2. Specifically, the material of the seal is at least one of salt, oxide, and a water-soluble polymer material. In other embodiments, the seal can also be made of a material that breaks when encountering a leaking liquid, shrinks in volume, and can also release the seal. Or the seal can also be made of a solid that can undergo a chemical change and turn into a liquid when encountering a leaking liquid.

[0042] In some embodiments, see Figure 2 , the seal is arranged in the lumen of the suction line 2; or, see Figure 3, the sealing member is coated on the outside of the first end. The sealing member is sealed in the tube cavity of the first end or coated on the outside of the first end, both of which can block the passage of gas and contact and block when there is leakage. The sealing member is arranged in the tube cavity of the first end, which is convenient for assembly. The sealing member is coated on the outside of the first end, which is convenient for observing the use status of the sealing member.

[0043] In some embodiments, the seal is block-shaped, and the outer end of the seal is located inside the end surface of the first end or flush with the end surface of the first end, and there is a gap between the end surface of the first end and the liquid collecting component 1. By setting the gap, the leaked liquid can contact the seal to release the sealing function of the seal.

[0044] In some embodiments, the outer end of the seal protrudes from the end surface of the first end and contacts the bottom surface of the liquid collecting component 1. It is understandable that when the seal is disposed in the tube cavity of the first end, a portion of it protrudes from the end surface of the first end. When the seal is wrapped outside the first end, the seal naturally protrudes from the end surface of the first end. When the seal is in contact with the bottom surface of the liquid collecting component 1, when there is leakage on the bottom surface, the seal can quickly contact the leakage, thereby connecting the liquid collecting component 1 with the suction component to quickly absorb the leakage. In other embodiments, the outer end of the seal can also maintain a certain distance from the bottom surface of the liquid collecting component 1, and the seal will only contact the leakage when the leakage meets a certain amount, that is, the sealant contacts the leakage when the leakage reaches the suction requirement corresponding to the distance.

[0045] In some embodiments, the blocking member 21 is a water-permeable membrane. The water-permeable membrane is a membrane that blocks gas from passing through and allows liquid to pass through, and can specifically be a hollow fiber ultrafiltration membrane, etc. The water-permeable membrane is provided at the first end of the pumping pipeline in a sealed connection, so that gas can be blocked from passing through and liquid can be allowed to pass through at the same time. Specifically, the water-permeable membrane can be bonded to the inside of the first end of the pumping pipeline, or the water-permeable membrane can be coated on the outside of the first end of the pumping pipeline and bonded.

[0046] In some embodiments, the leakage protection device also includes a sensor and a controller. Among them, the sensor is arranged in the liquid collecting part 1 to detect whether there is leakage; the controller is connected to the sensor and the suction device respectively, and is used to control the suction device to start when the sensor detects leakage. When the liquid cooling heat dissipation module leaks, the leakage is detected by the sensor, and the leakage signal is transmitted to the controller and an alarm can be issued. The controller can be specifically arranged in the host or the collector to issue an alarm. At the same time, the controller starts the suction device, and the leakage is collected into one or several liquid collecting parts 1 along with the liquid collecting structure. The seal of the suction pipeline 2 in the liquid collecting part 1 quickly dissolves after touching the liquid to release the seal, and the suction pipeline 2 becomes a passage. The leakage can leave the server along the suction pipeline 2, reducing the damage of the leakage to the server hardware and server information, and increasing the maintenance time of the maintenance personnel.
