In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, fig. 1 is a schematic diagram of a liquid-cooled tube leakage detection device for a server according to an embodiment of the present invention, fig. 2 is a schematic diagram of a composite layer in the liquid-cooled tube leakage detection device for the server, and fig. 3 is an exploded view of the composite layer in an embodiment.
The leakage detection device for the liquid cooling pipe of the server provided by the invention has high detection sensitivity, and can detect and find leakage faults of the liquid cooling pipe in time when the liquid cooling pipe leaks, so that operation and maintenance personnel can maintain the leakage detection device in time, and the continuous leakage of cooling liquid is avoided.
As shown in fig. 1, in the embodiment provided by the invention, the server liquid-cooled tube leakage detection device comprises a power module 1, a current detection unit 2, a conductive negative layer 6, a conductive positive layer 8 and a water-absorbing dielectric layer 7 arranged between the conductive positive layer 8 and the conductive negative layer 6. The negative pole of the power module 1 is electrically connected with the conductive negative pole layer 6 through a wire, the positive pole of the power module 1 is electrically connected with the conductive positive pole layer 8 through a wire, and the current detection unit 2 is connected with the power module 1 in series, i.e. the current detection unit 2 can be connected between the power module 1 and the conductive positive pole layer 8 in series, and can also be connected between the power module 1 and the conductive negative pole layer 6 in series. The water-absorbing dielectric layer 7 is arranged between the conductive positive electrode layer 8 and the conductive negative electrode layer 6, and when the water-absorbing dielectric layer 7 does not absorb the cooling liquid, the water-absorbing dielectric layer 7 plays a role in insulating and isolating the conductive positive electrode layer 8 and the conductive negative electrode layer 6; and after absorbing the coolant liquid of seepage when dielectric layer 7 absorbs, coolant liquid and dielectric layer 7 that absorbs water fill to expand between electrically conductive positive layer 8 and electrically conductive negative pole layer 6, switch on electrically conductive positive layer 8 and electrically conductive negative pole layer 6, power module 1 this moment, current detection unit 2, electrically conductive positive layer 8 and electrically conductive negative pole layer 6 constitute closed circuit, current detection unit 2 can detect the electric current, fortune dimension personnel only need observe current detection unit 2 and have or not the electric current can confirm whether the liquid cooling pipe takes place the seepage, it is convenient to observe.
When the liquid-cooled tube leakage detection device of the server is used, the conductive negative layer 6, the water absorption dielectric layer 7 and the conductive positive layer 8 need to be stacked layer by layer, then the conductive negative layer 6 or the conductive positive layer 8 is used as an inner layer to be coated on the periphery of the liquid-cooled tube, and finally the power module 1 and the current detection unit 2 are connected between the conductive positive layer 8 and the conductive negative layer 6 through a wire. When the liquid cooling tube is coated, the conductive negative electrode layer 6 is preferably used as an inner layer, and a direct current power supply is usually selected for the power supply module 1. Conductive negative layer 6, the dielectric layer 7 that absorbs water and conductive positive layer 8 three cladding behind the liquid cooling pipe, on the one hand can fully contact the coolant liquid that absorbs each position seepage of liquid cooling pipe, and on the other hand, conductive negative layer 6, the dielectric layer 7 that absorbs water and conductive positive layer 8 cladding the liquid cooling pipe, can reduce liquid cooling pipe and environment heat transfer, reduce the loss of the "cold volume" of coolant liquid.
The conductive negative electrode layer 6, the water-absorbing dielectric layer 7 and the conductive positive electrode layer 8 are generally rectangular film layers with basically the same size, the length of the rectangular film layer is equal to that of the liquid-cooled tube to be coated, and the width of the rectangular film layer is equal to or slightly smaller than the circumference of the liquid-cooled tube to be coated; further, the length and width of the water-absorbing dielectric layer 7 can be slightly larger than those of the conductive negative electrode layer 6 and the conductive positive electrode layer 8, and the three layers are stacked layer by layer, then coated on the periphery of the liquid cooling pipe, and bound and fixed by a binding belt.
In order to facilitate the cladding of the liquid cooling pipe by the conductive negative layer 6, the water absorption dielectric layer 7 and the conductive positive layer 8, the three layers are overlapped and fixedly connected in advance to form a composite layer, and circumferential relative rotation between the layers after the cladding is finished is avoided. Illustratively, the conductive negative electrode layer 6, the water-absorbent dielectric layer 7, and the conductive positive electrode layer 8 may be joined by sewing to form a composite layer. The composite layer functions as a control switch which is closed when the cooling liquid is sufficiently soaked in the water-absorbing dielectric layer 7 between the conductive negative layer 6 and the conductive positive layer 8, and is opened when the liquid-cooling pipe does not leak, that is, the water-absorbing dielectric layer 7 does not absorb the cooling liquid. Simultaneously, in order to facilitate the cladding of the composite layer to the liquid cooling pipe, the connecting pieces 11 are arranged at the two ends of the composite layer in the width direction, as shown in fig. 2, the connecting pieces 11 at the two ends of the composite layer in the width direction can be matched with each other to connect the composite layer to form a sleeve structure. For example, the connecting piece 11 can adopt the strap zip fastener or the magic subsides of sewing up both ends about the composite bed, and when adopting strap zip fastener or magic to paste, the strap zip fastener and the magic are pasted the homogeneous phase and are extended the setting from top to bottom to the composite bed to after the composite bed passes through connecting piece 11 and forms the sleeve structure, only connecting piece 11 connects, and do not have the electrically conductive positive pole layer 8 and the electrically conductive negative pole layer 6 direct contact of lower extreme on the composite bed.
In the above embodiment, the water-absorbing dielectric layer 7 may be made of an insulating material layer such as a resin film layer which can sufficiently absorb and permeate water, and sufficiently exerts its own insulating property and water-absorbing property; the conductive negative electrode layer 6 preferably adopts a hollow conductive layer, such as a conductive carbon fiber film, a metal wire mesh grid and the like, and the conductive negative electrode layer 6 adopts a hollow conductive layer which is favorable for the leaked cooling liquid to quickly flow to the water-absorbing dielectric layer 7; the conductive positive electrode layer 8 may be a conductive carbon fiber film. In addition, in order to facilitate the electrical connection between the power module 1 and the conductive positive electrode layer 8 and the conductive negative electrode layer 6, two ends of the conductive positive electrode layer 8 and the conductive negative electrode layer 6 in the length direction are both provided with convex lead welding areas 12, so that the conductive positive electrode layer 8 and the conductive negative electrode layer 6 can be conveniently connected through leads. The wire bonding area 12 of both the conductive positive electrode layer 8 and the conductive negative electrode layer 6 may be provided at the opposite end in the longitudinal direction.
Referring to fig. 3, in a preferred embodiment of the present invention, in order to improve the reliability of the liquid leakage detection device, the composite layer further includes an inner water-absorbing protective layer 10, the inner water-absorbing protective layer 10 is attached to the inner side of the conductive negative electrode layer 6, where the inner side specifically refers to the composite layer covering the periphery of the liquid cooling tube and attached to one side of the liquid cooling tube. By arranging the inner water absorption protective layer 10, the inner water absorption protective layer 10 is directly contacted with the liquid cooling pipe, and compared with the hollow conductive negative layer 6, the cooling liquid leaked from the pipe wall of the liquid cooling pipe can be absorbed more easily and directly, and the cooling liquid can be infiltrated to the water absorption dielectric layer 7 more uniformly; meanwhile, the arrangement of the inner water absorption protection layer 10 increases the resistance between the conductive negative layer 6 and the liquid cooling pipe, and the electric leakage to the liquid cooling pipe when the liquid cooling pipe is a metal pipe and the conductive negative layer 6 and the conductive positive layer 8 are conducted is avoided.
Preferably, the composite layer further comprises an outer water absorption protective layer 9 disposed outside the conductive positive electrode layer 8, that is, when the composite layer is wrapped around the liquid cooling pipe, the outer water absorption protective layer 9 is located at the outermost layer of the sleeve structure. Generally speaking, the thickness of the outer water-absorbing protective layer 9 is the largest or the outer water-absorbing protective layer 9 can be arranged into multiple layers, and the arrangement has the advantages that on one hand, when the leakage detection device detects leakage of the liquid cooling pipe, the outer water-absorbing protective layer 9 can continuously absorb leaked cooling liquid, so that certain processing time is reserved for operation and maintenance personnel from fault finding to fault removing, namely the outer water-absorbing protective layer 9 plays a role in buffering; on the other hand, the outer water absorption protective layer 9 can absorb or isolate water vapor in the air to a certain extent by matching with the inner water absorption protective layer 10, so that water vapor condensation at the pipe wall of the liquid cooling pipe is reduced, and misjudgment of the liquid cooling pipe leakage detection device caused by the water condensation inflating the water absorption dielectric layer 7 is avoided. When the composite layer is coated on the liquid cooling pipe, the outermost layer of the composite layer can be coated with a plastic film to further isolate water vapor.
In order to optimize the above embodiment, improve the convenience of detection and find the leakage fault of the liquid cooling pipe in time, the liquid cooling pipe leakage detection device of the server provided by the invention further comprises a controller 4 and an alarm 5. The alarm 5 and the current detection unit 2 are both connected with the controller 4, when the current detection unit 2 detects a current signal, the current signal is sent to the controller 4, the controller 4 controls the alarm 5 to operate according to the existence of the current signal, if the current signal exists, the leakage of the liquid cooling pipe is indicated, and the controller 4 controls the alarm 5 to alarm. Alarm 5 can be bee calling organ, pilot lamp, can also be integrative with controller 4 is integrated, if controller 4 and alarm 5 adopt the computer, current detection unit 2 is connected to the computer, and current detection unit 2 carries the computer with the current value that detects in real time, when the current value is nonzero, utilizes the display interface suggestion liquid cooling pipe seepage. It should be noted that, in order to avoid the situation that the short-circuit current of the power module 1 is too large when the conductive positive electrode layer 8 and the conductive negative electrode layer 6 are conducted, the power module 1 may also be connected in series with the protection resistor 3 or directly connected in series with the alarm 5 and the power module 1 as needed, and details are not repeated here.
