Description

server

The invention relates to a server, particularly a server with a liquid leakage detection system.

With the gradual improvement of the performance of electronic components such as processors in the server, more heat and higher temperature will be generated, so the conventional air-cooled heat dissipation method has gradually become inadequate. In order to solve the heat dissipation problem of the server, the industry is gradually changing to a liquid-cooled heat dissipation method. Through the heat exchange between the coolant and the electronic components, the heat dissipation capacity of the server can be effectively improved.

Generally speaking, most of the cooling liquid is transported through liquid-cooled pipes. However, the liquid-cooled tube used to transport the coolant is easily shaken during the process of transporting the server, which increases the probability of damage to the liquid-cooled tube and even leaks. Since the common coolant is a mixed solution of pure water and propylene glycol, it is a conductive solution. Once the liquid leakage occurs too serious, it is easy to short-circuit the electronic components in the server and cause damage to the electronic components. Therefore, how to detect the leakage of liquid-cooled pipes is one of the urgent problems for R&D personnel in this field.

The present invention is to provide a server to solve the problem of liquid-cooling tube leakage in the prior art.

The server disclosed in an embodiment of the present invention includes a chassis, a processor, a liquid cooling tube, and a liquid leakage detection system. The processor is arranged in the chassis. The liquid cooling pipe is installed in the processor. The leakage detection system includes a circuit board and a first detection line. The circuit board is arranged in the chassis. The first detection line is arranged in the liquid cooling tube and electrically connected to the circuit board.

According to the server disclosed in the above embodiment, the leakage detection system provided in the chassis can detect through the first detection line whether the coolant inside the liquid cooling tube has leaked, and the first detection line can transmit the detection result to the electric Road board.

The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention and provide a further explanation of the scope of the patent application of the present invention.

The following will describe an embodiment of the present invention. First, please refer to FIG. 1 to FIG. 3. FIG. 1 is a three-dimensional schematic diagram of a server 10a according to an embodiment of the present invention. FIG. 2 is a partial three-dimensional diagram of the server 10a of FIG. 1. FIG. 3 is a schematic plan view of the server 10a of FIG. 2.

The server 10a of this embodiment includes a rack 100a, at least one chassis 200a, at least one processor 300a, at least one liquid cooling pipe 400a, and at least one liquid leakage detection system 500a. The chassis 200a is installed in the rack 100a. The processor 300a is, for example, an arithmetic element that generates a large amount of heat, and the processor 300a is disposed in the chassis 200a. The liquid cooling tube 400a is disposed on the processor 300a to take away the heat generated by the processor 300a by means of heat exchange through the cooling liquid (not shown) flowing inside the liquid cooling tube 400a. The liquid leakage detection system 500a is installed in the case 200a.

In this embodiment, the number of chassis 200a is multiple and the chassis 200a are arranged in the rack 100a, the number of processors 300a provided in each chassis 200a is multiple, and the liquids provided in each chassis 200a The number of the cold pipe 400a is one, and the number of the leakage detection system 500a provided in each cabinet 200a is one, but the present invention is not limited to this. In some embodiments, the number of chassis may be only one, the number of processors provided in each chassis may be only one, and the number of liquid cooling pipes provided in each chassis may be multiple, or each The number of leakage detection systems set in one chassis can be multiple.

In this embodiment, the liquid leakage detection system 500a provided in the cabinet 200a can detect whether the cooling liquid inside the liquid cooling pipe 400a leaks. Specifically, the liquid leakage detection system 500a includes a circuit board 510a and a first detection line 520a. The circuit board 510a is disposed on the chassis 200a, and the first detection line 520a is disposed on the liquid cooling tube 400a and electrically connected to the circuit board 510a. The liquid leakage detection system 500a can detect the leakage of the coolant inside the liquid cooling tube 400a through the first detection line 520a, and the first detection line 520a can transmit the detection result to the circuit board 510a.

Please refer to FIG. 4 and FIG. 5 to describe in more detail the method of detecting leakage by the first detection line 520a. FIG. 4 is a schematic front sectional view of the first detection line 520a of the server 10a in FIG. 2. FIG. 5 is a schematic side sectional view of the first detection line 520a of the server 10a in FIG. 2. As shown in FIG. 4, in this embodiment and some embodiments of the present invention, the first detection line 520a may further include a core 521a, an insulating layer 522a, and a covering layer 523a. The core 521a is located in the insulating layer 522a, and the insulating layer 522a is located in the covering layer 523a. In other words, the first detection line 520a is composed of the core 521a, the insulating layer 522a, and the covering layer 523a in order from the inside to the outside.

The insulating layer 522a has at least one first opening 5221a, and the covering layer 523a has at least one second opening 5231a. In this embodiment and some embodiments of the present invention, the number of the first openings 5221a is multiple, and the number of the second openings 5231a is multiple, but the present invention is not limited thereto. In some embodiments, the insulating layer may only have one first opening, and the covering layer may only have one second opening. In this embodiment and some embodiments of the present invention, the first opening 5221a communicates with the second opening 5231a, and the core 521a communicates with the outside through the first opening 5221a and the second opening 5231a. In other words, the first opening 5221a and the second opening 5231a expose the core 521a to the outside.

The material of the core 521a is, for example, stainless steel, and the core 521a has conductivity. The insulating layer 522a has electrical insulation. The material of the coating layer 523a is, for example, nylon, and the coating layer 523a has electrical insulation and capillary function. When the cooling liquid inside the liquid cooling tube 400a leaks, the coating layer 523a will absorb and diffuse the cooling liquid by its own capillary action. Once the cooling liquid diffused to the second opening 5231a reaches a certain amount, the cooling liquid will pass through the first opening 5221a and contact the core 521a, causing the conductivity of the core 521a to change. The conductivity change of the core 521 is, for example, a change in the resistance of the core 521a, and the result of the change in resistance of the core 521a is transmitted to the circuit board 510a. Based on the result of the resistance change of the core 521a, the circuit board 510a can determine whether the liquid cooling tube 400a is leaking.

In addition, the electrical insulation of the insulating layer 522a can ensure that the cooling liquid absorbed by the coating layer 523a needs to pass through the first opening 5221a and the second opening 5231a to change the conductivity of the core 521a to avoid some moisture. As a result, the conductivity of the core 521a is changed, so that the possibility of misjudgment of coolant leakage can be reduced. In some embodiments, the first detection line can also be provided without an insulating layer and a coating layer, and only a stainless steel core can be used to detect liquid leakage.

In this embodiment and some embodiments of the present invention, the first openings 5221a are separated from each other by a distance of, for example, 25 mm, and the second openings 5231a are separated from each other by a distance of, for example, 25 mm. In this way, it can be ensured that the detection points for liquid leakage are sufficient, and the first opening 5221a and the second opening 5231a can be closer to the place where there is a greater chance of liquid leakage depending on the actual configuration of the liquid cooling tube 400a inside the chassis 200a.

Please refer to Figure 2, Figure 4 and Figure 5 together. In this embodiment and some embodiments of the present invention, the chassis 200a may further have a bottom surface 201a. When the server 10a is placed on a platform such as the ground, the chassis 200a is set in the rack 100a with the bottom surface 201a facing the platform, and the first detection line 520a is closer to the bottom surface 201a of the chassis 200a than the liquid cooling pipe 400a. In this way, when the cooling liquid inside the liquid cooling tube 400a leaks, the cooling liquid will be affected by gravity and flow toward the bottom surface 201a, so it is easier to be adsorbed by the covering layer 523a, and therefore it is easier to detect by the aforementioned method To the leakage situation.

Please refer to Figure 2 and Figure 6. FIG. 6 is a three-dimensional schematic diagram of the liquid leakage detection system 500a of the server 10a in FIG. 2. In this embodiment and some embodiments of the present invention, the liquid leakage detection system 500a may further include at least one connector 530a. The connector 530a is, for example, a wire quick connector and includes a female connector 531a and a male connector 532a. The female connector 531a is disposed on the circuit board 510a. The first detection line 520a is provided on the male connector 532a in a screw-locked manner, for example. The male connector 532a is detachably disposed on the female connector 531a so that the first detection line 520a is electrically connected to the circuit board 510a through the connector 530a. In this way, the first detection line 520a can be quickly and simply installed on the circuit board 510a, and the first detection line 520a can transmit the leakage detection result to the circuit board 510a through the connector 530a.

The liquid leakage detection system 500a may further include a signal line 540a. The signal line 540a is electrically connected to the circuit board 510a and the processor 300a. As mentioned above, when the leakage detection system 500a detects the leakage of the coolant inside the liquid cooling tube 400a through the first detection line 520a, the first detection line 520a can transmit the detection result to the circuit board 510a. Then, the circuit board 510a can transmit the detection result to the processor 300a through the signal line 540a. After the processor 300a receives the detection result of the coolant leakage, it can stop the circulation of the coolant by, for example, sending a control signal to prevent the leakage from becoming more serious; or by sending a visual or audible warning, for example To inform users, and allow users to take appropriate follow-up measures.

The following will only describe the differences between another embodiment of the present invention and some of the foregoing embodiments, and the remaining similarities will be omitted. In this embodiment and some embodiments of the present invention, the diameter of the entire liquid cooling tube 400b may be different due to the consideration of the flow rate of the cooling liquid inside the liquid cooling tube 400b. Specifically, the liquid cooling tube 400b may further include a first tube portion 410b and a second tube portion 420b. The first pipe portion 410b is disposed on the processor 300b, and the second pipe portion 420b is disposed on the chassis 200b. The first pipe portion 410b communicates with the second pipe portion 420b, and the pipe diameter of the first pipe portion 410b is smaller than the pipe diameter of the second pipe portion 420b. The first detection line 520b is disposed on the first pipe portion 410b and the second pipe portion 420b and is wound around the junction of the first pipe portion 410b and the second pipe portion 420b. Since the junction between the first pipe portion 410b and the second pipe portion 420b may be more prone to leakage than other parts of the liquid-cooled pipe 400b, by wrapping around the junction of the first pipe portion 410b and the second pipe portion 420b The first detection line 520b can be forced to detect liquid leakage at the winding place.

The first pipe portion 410c, the second pipe portion 420c, and the third pipe portion 430c are in communication with each other. The pipe diameter of the first pipe portion 410c is smaller than the pipe diameter of the second pipe portion 420c, and the pipe diameter of the second pipe portion 420c is smaller than the pipe diameter of the second pipe portion 420c. The pipe diameter of the third pipe part 430c. The first detection wire 520c is arranged on the first tube portion 410c and the second tube portion 420c and is wound around the junction of the first tube portion 410c and the second tube portion 420c, and the second detection wire 550c is wound around the second tube portion 420c and the second tube portion 420c. The junction of the third pipe 430c. Since the junction between the first pipe portion 410c and the second pipe portion 420c and the junction between the second pipe portion 420c and the third pipe portion 430c may be more prone to leakage than other parts of the liquid-cooled pipe 400c, by winding The first detection line 520c at the junction of the first pipe portion 410c and the second pipe portion 420c and the second detection line 550c wound at the junction of the second pipe portion 420c and the third pipe portion 430c can be forced to detect the twisted area The leakage situation.

In some embodiments, the first detection line may further include a core, an insulating layer, and a covering layer. When the cooling liquid inside the liquid cooling tube leaks, the coating layer will use its own capillary action to absorb and diffuse the cooling liquid. Once the cooling liquid spreading to the second opening reaches a certain amount, the cooling liquid will pass through the first opening and contact the core, causing the conductivity of the core to change. The circuit board can determine whether the liquid cooling tube is leaking. Situation.

In some embodiments, the first detection line is closer to the bottom surface of the chassis than the liquid cooling tube. In this way, when the cooling liquid inside the liquid cooling tube leaks, the cooling liquid will flow toward the bottom surface under the influence of gravity, so it is easier to be adsorbed by the coating layer, and therefore it is easier to detect the leakage.

In some embodiments, the leakage detection system may further include a signal line. The circuit board can transmit the test result to the processor through the signal line.
