Description

Technical Field

[0001] The utility model belongs to the technical field of server accessories, in particular to a liquid cooling pipe leakage detection device. Background Art

[0002] In computer design architecture, as CPU power consumption increases, the traditional method of using fans for heat dissipation is subject to physical limits and will no longer meet the needs of high-power CPU heat dissipation, which will cause server system downtime. In addition, as energy efficiency is increasingly valued, the use of liquid cooling can effectively improve energy efficiency and effectively reduce power output. More and more new technologies use liquid cooling to meet computer room requirements. This is especially evident in high-power components such as CPU / GPU. In the use of liquid cooling, the biggest problem currently comes from the risk of short circuits caused by leakage, so there needs to be a leakage detection mechanism to continuously monitor the leakage status. Once a leakage is detected, the server needs to be shut down immediately to avoid a short circuit.

[0003] In the existing technology, the main method is based on the design of the liquid cooling radiator supplier, which mostly uses a detection line wrapped around the water pipe. When the detection line senses moisture, it feeds back a signal to the BMC controller, which is informed of the leakage condition and then realizes the shutdown function.

[0004] The prior art has the following disadvantages:

[0005] a. This detection line depends on the supplier's process and design. Different suppliers cannot unify the method or interface, which may cause functional inconsistency between the main material and the substitute material. It is easy to cause misjudgment or misinterpretation, and it is not conducive to the developer's design of the BMC controller function.

[0006] b. This detection line is provided by the manufacturer and is made of the same material as the radiator body. This will increase the cost of the radiator body, complicate the assembly process, and increase the replacement of damaged ones. In addition, due to the complex process, the delivery time of the radiator will be extended, which will easily lead to problems in the supply chain.

[0007] c. The design is complex and cumbersome, which increases the damage rate of materials and the probability of RMA. It is a cumbersome problem for production preparation and return for rework, which brings great inconvenience to the factory production.

[0008] d. In addition, the detection line is laid along the periphery of the water pipe, and the leakage point cannot be detected in time, causing the leaked liquid to spread to the peripheral components, and some of the liquid will contaminate the surrounding components; and the leakage point generally occurs at the joint. Utility Model Content

[0009] In order to solve the problem that the wiring and assembly of the detection line for sensing liquid leakage in the prior art is complicated and the leakage of liquid cannot be absorbed, resulting in contamination of surrounding components, the utility model provides a liquid cooling tube leakage detection device which can absorb the leaked liquid and avoid contamination of surrounding components.

[0010] The utility model is realized by the following technical solutions:

[0011] A liquid cooling pipe leakage detection device comprises a water collecting box arranged below the joint of the liquid cooling pipe body, wherein the water collecting box is provided with a waterproof belt capable of crossing the joint of the liquid cooling pipe body; a detection component capable of acting on liquid is provided on the water collecting box on one side of the waterproof belt, wherein the detection component comprises a detection wire connected to an alarm, wherein a detection head is provided at one end of the detection wire away from the alarm, and the detection head extends to the inner bottom surface of the water collecting box.

[0012] The water collecting box is arranged below the joint of the liquid cooling tube body, which helps to prevent the leaked liquid from contaminating the surrounding components and causing downtime; the waterproof belt arranged in the water collecting box spans the upper part of the liquid cooling tube body, which helps to prevent the liquid from splashing outward due to pressure; the detection component is installed on the water collecting box, which is convenient and fast, and can quickly detect the occurrence of leakage.

[0013] A further improvement of the utility model is that the detection assembly further includes a fixing card, the fixing card sleeve is arranged between the detection head and the detection wire; the fixing card is provided with a groove that can match with the side wall of the water collection box. The groove on the fixing card matches with the side wall of the water collection box, which helps to improve the installation convenience; and the fixing card helps to fix the detection head, thereby improving the detection accuracy of the leakage.

[0014] A further improvement of the utility model is that a fixing hole is provided on the side wall of the water collecting box, and a locking protrusion that can cooperate with the fixing hole is provided on the inner wall of the groove. The fixing protrusion cooperates with the fixing hole to complete the stable installation of the fixing card on the water collecting box.

[0015] A further improvement of the utility model is that the fixing hole is centrally arranged on the side wall of the water collecting box on one side of the axis of the liquid cooling tube body, which helps to avoid interference with the layout of the liquid cooling tube body caused by the installation of the fixing card and optimizes the structural layout.

[0016] A further improvement of the utility model is that guide plates are provided on both sides of the fixing hole, and the two guide plates are arranged on the inner wall of the water collecting box. The guide plates provide guidance for the installation of the fixing card on the water collecting box, thereby improving the convenience of operation.

[0017] A further improvement of the utility model is that slopes are respectively arranged on both sides of the fixing hole, and the two slopes are arranged on the inner bottom surface of the water collecting box. The slopes can gather the liquid in the water collecting box to the middle, so that the detection head can sense the liquid in time.

[0018] A further improvement of the utility model is that a hand-held portion is provided on the upper part of the fixing card to facilitate the gripping of the fixing card.

[0019] A further improvement of the utility model is that the water collecting box is provided with a wire groove matched with the liquid cooling tube body. The wire groove can limit the placement of the liquid cooling tube body to prevent the liquid cooling tube body from deviating, resulting in an increase in the force at the joint of the liquid cooling tube body, thereby reducing the risk of liquid leakage.

[0020] A further improvement of the utility model is that both ends of the waterproof belt are connected with counterweight blocks respectively. The counterweight blocks can make the waterproof belt cover the liquid cooling pipe body to prevent it from slipping outward easily.

[0021] A further improvement of the utility model is that a limit bar is arranged in the water collecting box, and the limit bar cooperates with the side wall of the water collecting box to fix the counterweight block.

[0022] It can be seen from the above technical scheme that the beneficial effects of the utility model are: the water collecting box is arranged below the joint of the liquid cooling tube body, which helps to prevent the leaked liquid from contaminating the surrounding components and causing downtime; the waterproof belt arranged in the water collecting box spans the upper part of the liquid cooling tube body, which helps to prevent the liquid from splashing outward due to pressure; the detection component is installed on the water collecting box, which is convenient and quick, and can quickly detect the occurrence of leakage.
