Fig. 1 is a schematic diagram of a server system in an embodiment of the present application, fig. 2 is a schematic diagram of a pipeline transportation structure in an embodiment of the present application, and fig. 3 is a schematic partial sectional view of the pipeline transportation structure shown in fig. 2. As shown in fig. 1 to 3, a pipeline conveying structure 100 provided in an embodiment of the present application includes an inner pipe 110, a leakage detecting member 120 and an outer pipe 130, wherein one end of the inner pipe 110 is used for being connected with a liquid reservoir, and the other end is used for being connected with a server 200, so as to convey cooling liquid stored in the liquid reservoir to the server 200; the leakage detecting member 120 is connected to the outer wall of the inner tube 110; the liquid leakage detecting member 120 has a terminal 121, and the terminal 121 is used for being electrically connected with an external power supply, so that the liquid leakage detecting member 120 forms a detection loop; the outer tube 130 is sleeved on the outer wall of the inner tube 110, and the inner wall of the outer tube 130 abuts against the liquid leakage detecting member 120.

Thus, when the inner pipe 110 leaks, the leakage can be blocked by the inner wall of the outer pipe 130 and guided to the leakage detecting member 120 on the outer wall of the inner pipe 110, and the weak current passing through the water changes the impedance value of the leakage detecting member 120, thereby reminding the operator. Through with outer pipe fitting 130 cover establish on the outer wall of inner pipe fitting 110 to fasten leak detection spare 120, with the connection effect that promotes leak detection spare 120 and inner pipe fitting 110, make inner pipe fitting 110 and leak detection spare 120 in close contact with, the coolant liquid that inner pipe fitting 110 oozes can be guided to leak detection spare 120 by outer pipe fitting 130, in order to improve leak detection's accuracy and reliability. Meanwhile, the outer pipe fitting 130 is sleeved on the outer wall of the inner pipe fitting 110, so that the inner pipe fitting 130 is more convenient to install and detach, when liquid leakage occurs, the inner pipe fitting 110 is convenient to maintain and replace, the reliability of conveying cooling liquid by the inner pipe fitting 110 is improved, and the running stability of the server 200 is improved.

As shown in fig. 2, in one embodiment, the leak detection member 120 includes a leak detection wire that is spirally wound around the outer wall of the inner tube 110. Through the spiral winding mode, the connection tightness of the liquid leakage detection line and the inner pipe fitting 110 can be improved, so that the outer pipe fitting 130 can play a role in fixing and guiding, and the liquid seeped out from the inner pipe fitting 110 can be guided to the liquid leakage detection line in time, so that an operator can monitor the liquid leakage condition; and can also reduce the possibility that the pipeline conveying structure 100 leads to the deformation of the liquid leakage detection line in the bending process, and improve the service life and detection accuracy of the pipeline conveying structure. Wherein, the liquid leakage detection line can be flat or cylindrical; the outer tube 130 may be made of transparent PE material, which facilitates inspection of the winding quality.

In other embodiments, the leakage detecting member may be a cable for detecting leakage of oil, a cable for detecting leakage of acid, a cable for detecting leakage of oil, or a cable for detecting leakage of other solvents, in addition to the cable for detecting leakage of water. Different types of leak detection lines may be used for different media, such as an ASC1100 detection band for leak detection, an ASC9100 detection band for leak detection.

In one embodiment, the outer tubular member is deformed by shrinkage when the outer tubular member is at a predetermined temperature. For example, the assembled pipeline conveying structure is placed in an incubator with the temperature of 100-200 ℃ for a period of time, and the outer pipe is heated to deform. Through the shrinkage deformation of outer pipe fitting to the clearance between compression outer pipe fitting and the inner tube spare is with the more firm fixing of leak detection line on the inner tube fitting, thereby more timely detection weeping condition improves the reliability of weeping detection effect.

As shown in fig. 2, in one embodiment, the leak detector 120 is bonded to the outer wall of the inner tube 110. Through the mode of bonding, further promote the connection effect of weeping detection spare 120 and interior pipe fitting 110, guarantee that the liquid that interior pipe fitting 110 oozes can in time be guided to weeping detection spare 120 to the operating personnel monitors the weeping condition. The leak detection member 120 and the inner tube member 110 may be bonded and fixed by an adhesive tape. In other embodiments, besides being an adhesive manner, the outer wall of the inner tube 110 may be connected with a ring of iron sheet, and the leakage detection member 120 is connected with a magnet, so that the leakage detection member 120 and the inner tube 110 are adsorbed by magnetic force, and connection tightness of the two is improved.

As shown in fig. 1 and 2, in one embodiment, the pipeline conveying structure 100 further includes a control module 140, where the control module 140 is electrically connected to the terminal 121 of the leakage detecting member 120, and the control module 140 supplies power to the leakage detecting member 120 to form a detection loop. Meanwhile, the control module 140 can acquire parameters of the detection loop, and compare the acquired parameter values with normal value ranges to judge whether a liquid leakage situation occurs. In other embodiments, the control module 140 and the leak detector 120 may be connected by a connector.

In a specific embodiment, the parameter of the detection loop comprises an impedance value. When the inner pipe has liquid leakage, the liquid leakage detection part is immersed by liquid, which is equivalent to a parallel loop, so that the impedance value of the detection loop is smaller than the lower limit of the normal value range. In this way, by acquiring the impedance value of the detection circuit and comparing the impedance value with the normal value, it is possible to determine whether or not a leakage condition has occurred. When the pipeline conveying structure does not leak the cooling liquid and the leakage detecting piece is not broken, the impedance value of the leakage detecting piece is in a normal value range, namely the normal value corresponds to the impedance value when no leakage occurs.

In other embodiments, the parameter of the detection loop may be a current value. When the coolant seeps out from the inner pipe member to the leak detection member, the resistance value thereof decreases, and as is known from ohm's law, when the power supply voltage is inconvenient, the current value of the detection circuit increases. Thus, by acquiring the current value of the detection circuit and comparing the current value with the normal value, it is possible to determine whether or not a liquid leakage condition occurs.

In one embodiment, the control module includes a first resistor and a first power supply, one end of the first resistor is connected with the first power supply, the other end of the first resistor is electrically connected with the first end of the leakage detection member, and the second end of the leakage detection member is grounded. At this time, the first resistor is connected in series with the leakage detecting member. Under the condition that the input voltage of the detection loop is unchanged, when the inner pipe is leaked, the voltage value obtained by the leakage detection part is reduced, and the voltage value obtained by the first resistor is increased, so that whether the pipeline conveying structure leaks or not can be monitored by monitoring the voltage value of the leakage detection line or the voltage value of the first resistor.

In some embodiments, the control module further comprises a wire breakage detection member electrically connected to the leakage detection member. When the leakage detection member breaks, the impedance value of the leakage detection member is larger than the upper limit of the normal value range, so that the current value of the loop is smaller than the lower limit of the normal value range. The leakage detection part is used for detecting the current value of the loop and outputting a first signal; the broken wire detecting piece is used for detecting the current of the loop and outputting a second signal. The leakage detection part and the broken wire detection part can be analog-to-digital conversion circuits formed by comparators and can also be analog-to-digital conversion chips.

Specifically, the first signal includes a high level signal and a low level signal, and the second signal includes a high level signal and a low level signal. For example, when the pipeline conveying structure has no leakage of the cooling liquid and the leakage detecting member has no fracture, the first signal output by the leakage detecting member is at a low level, and the second signal output by the broken line detecting member is at a high level; when the pipeline conveying structure has a liquid leakage condition and the liquid leakage detection part is not broken, the first signal output by the liquid leakage detection part is at a high level, and the second signal output by the broken line detection part is at a high level; when the leakage detection piece breaks and the pipeline conveying structure does not leak the cooling liquid, the first signal output by the leakage detection piece is at a low level, and the second signal output by the broken line detection piece is at a low level; when the pipeline conveying structure is leaked with cooling liquid and the leakage detecting piece is broken, the first signal output by the leakage detecting piece is at a high level, and the second signal output by the broken line detecting piece is at a low level. Therefore, whether the pipeline conveying structure has a liquid leakage condition or a breakage condition of a liquid leakage detection part is conveniently judged, and the operation reliability of the server is improved.

As shown in fig. 2 and 3, in one embodiment, the outer tube 130 sequentially includes a supporting layer 131 and a protecting layer 132 from inside to outside, and the supporting layer 131 abuts against the liquid leakage detecting member 120. Specifically, the supporting layer 131 includes an annular supporting ring, and the supporting layer 131 may be made of a plastic material with higher hardness by abutting the supporting ring on the outer wall of the inner tube 110 to improve the connection effect between the inner tube 110 and the leakage detecting member 120. The protective layer 132 is used for protecting the pipeline transportation structure 100 from being scratched or broken during production and transportation, and the protective layer 132 may be a polyethylene layer.

As shown in fig. 2 to 4, in one embodiment, the inner wall of the protective layer 132 is provided with a plurality of liquid storage tanks 1321, and a liquid level relay 133 is installed in the liquid storage tanks 1321; the protective layer 132 is connected with a liquid discharge pipe 134, one end of the liquid discharge pipe 134 is communicated with a liquid storage tank 1321, and the other end of the liquid discharge pipe 134 is provided with an electromagnetic valve 135 electrically connected with a liquid level relay 133; solenoid valve 135 is responsive to level relay 133 to cause solenoid valve 135 to open.

Specifically, when the inner pipe 110 leaks, the leakage flows from the leakage port of the inner pipe 110 into the outer wall of the inner pipe 110 and into the liquid storage tank 1321 near the leakage port, so that the liquid level relay 133 in the liquid storage tank 1321 is closed, and the solenoid valve 135 of the corresponding liquid discharge pipe 134 is controlled to be opened, so that the leakage is discharged through the liquid discharge pipe 134. Meanwhile, the control module 140 further comprises an alarm electrically connected with the electromagnetic valve 135, and after the electromagnetic valve 135 is opened, the alarm gives an alarm to remind the staff of the leakage of the inner pipe fitting 110, so that the staff can repair the leakage point of the inner pipe fitting 110 or replace the inner pipe fitting 110 in time.

In one embodiment, the pipeline conveying structure further comprises a drying module connected with the leakage detection member, and the drying module is used for evaporating liquid attached to the leakage detection member. The drying module comprises an electric heating wire, and after the inner pipe fitting is overhauled, the electric heating wire is used for heating the leakage detection line, so that the part which is immersed by liquid originally is dried rapidly, and false alarm is avoided. The leakage detection parts and the electric heating wires work independently, no electric signal or control signal is transmitted between the leakage detection parts and the electric heating wires, and the electric heating wires are isolated from the leakage detection parts in an insulating way to avoid mutual interference.

Wherein, the electric heating wire includes a plurality of, and the resistivity of a plurality of electric heating wires is different. When in use, the electrothermal wire with corresponding resistivity can be selected and electrified according to the use environment. For example, for a relatively humid use environment, an electric wire with a small resistivity may be selected, and the heating effect of the electric wire is good, while for a less humid use environment, an electric wire with a large resistivity may be selected, and the heating effect of the electric wire is poor, but the electric energy can be effectively saved on the premise of evaporating water vapor.

In still other embodiments, the electrothermal layer includes a first conductive layer, a second conductive layer, and a filler layer. The filling layer is located between the first conductive layer and the second conductive layer, and conductive particles are doped in the filling layer, and the conductive particles are used for forming a conductive path between the first conductive layer and the second conductive layer. The resistivity of the electrothermal layer is the resistivity formed by the first conductive layer, the second conductive layer and the conductive particles. When the external power supply supplies power to the electric heating layer, the whole electric heating layer is equivalent to a conductive wire due to the existence of conductive particles, so that the electric heating layer can continuously heat, and water vapor on the leakage detection piece is evaporated.

In some embodiments, the control module further comprises a second power supply electrically connected to the electric heating wire for forming a continuous heating circuit. The first power supply and the second power supply can be integrated in a power supply with multiple power supply ports, and different power supply ports are respectively and electrically connected with the leakage detection piece and the electric heating wire.

Next, the outer tube 130 is sleeved outside the inner tube 110, and the outer tube 130 may be made of transparent material, so that an operator can check the winding quality of the leakage detection member 120 conveniently. After the sleeving is finished, the temperature in the incubator is adjusted to the thermal shrinkage temperature, and the pipeline conveying structure 100 is placed in the incubator. After a period of time, the pipe conveying structure 100 is taken out from the incubator, and the two ends of the outer pipe 130 are subjected to glue treatment, so that the cooling liquid is prevented from penetrating into the leakage detection member 120, and false alarm occurs.
