The present invention will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present invention.
Referring to fig. 1 to 3, fig. 1 is a schematic diagram of a liquid leakage detection device for a liquid-cooled tube of a server according to an embodiment of the present invention, fig. 2 is a visual diagram of a composite layer in the liquid leakage detection device for the liquid-cooled tube of 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 timely detect and discover leakage faults of the liquid cooling pipe when the liquid cooling pipe leaks, so that operation and maintenance personnel can timely maintain the liquid cooling pipe, and 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 electrode layer 6, a conductive positive electrode layer 8 and a water-absorbing dielectric layer 7 arranged between the conductive positive electrode layer 8 and the conductive negative electrode layer 6. The negative electrode of the power module 1 is electrically connected with the conductive negative electrode layer 6 through a wire, the positive electrode of the power module 1 is electrically connected with the conductive positive electrode layer 8 through a wire, and the current detection unit 2 is connected with the power module 1 in series, that is, the current detection unit 2 can be connected between the power module 1 and the conductive positive electrode layer 8 in series, and can also be connected between the power module 1 and the conductive negative electrode 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 from the conductive negative electrode layer 6; and after the dielectric layer 7 absorbs the coolant liquid of seepage, coolant liquid and dielectric layer 7 swell between conductive positive electrode layer 8 and conductive negative electrode layer 6, switch on conductive positive electrode layer 8 and conductive negative electrode layer 6, power module 1, current detection unit 2, conductive positive electrode layer 8 and conductive negative electrode layer 6 constitute closed loop this moment, current detection unit 2 can detect the electric current, operation and maintenance personnel only need observe current detection unit 2 have the electric current can confirm whether the liquid cooling pipe takes place the seepage, it is convenient to observe.
When the liquid leakage detection device of the server liquid-cooled tube is used, after the conductive negative electrode layer 6, the water-absorbing dielectric layer 7 and the conductive positive electrode layer 8 are stacked layer by layer, the conductive negative electrode layer 6 or the conductive positive electrode 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 electrode layer 8 and the conductive negative electrode layer 6 through wires. In the case of coating the liquid-cooled tube, the conductive negative electrode layer 6 is preferably used as an inner layer, and the power module 1 is usually a dc power supply. After the conductive negative electrode layer 6, the water-absorbing dielectric layer 7 and the conductive positive electrode layer 8 are coated on the liquid-cooled tube, on one hand, the conductive negative electrode layer 6, the water-absorbing dielectric layer 7 and the conductive positive electrode layer 8 can fully contact the cooling liquid leaking from each part of the absorption liquid-cooled tube, on the other hand, the conductive negative electrode layer 6, the water-absorbing dielectric layer 7 and the conductive positive electrode layer 8 coat the liquid-cooled tube, so that the heat exchange between the liquid-cooled tube and the environment can be reduced, and the loss of the cooling capacity of the cooling liquid is reduced.
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 equal sizes, the length of the rectangular film layers is equal to the length of the liquid-cooled tube to be coated, and the width of the rectangular film layers 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 water-absorbing dielectric layer, the conductive negative electrode layer and the conductive positive electrode layer are stacked layer by layer, then are coated on the periphery of the liquid cooling pipe and are bound and fixed by using a binding belt.
In order to facilitate the coating of the liquid cooling tube by the conductive negative electrode layer 6, the water absorption dielectric layer 7 and the conductive positive electrode layer 8, the conductive negative electrode layer 6, the water absorption dielectric layer 7 and the conductive positive electrode layer 8 are overlapped and fixedly connected in advance to form a composite layer, and the relative rotation between the layers in the circumferential direction is avoided after the coating is completed. Illustratively, the conductive negative electrode layer 6, the water absorbing dielectric layer 7, and the conductive positive electrode layer 8 may be connected by stitching to form a composite layer. The composite layer acts as a control switch which is closed when the coolant fully wets the water-absorbing dielectric layer 7 between the conductive negative electrode layer 6 and the conductive positive electrode layer 8, and which is opened when the liquid-cooled tube is not leaky, i.e. the water-absorbing dielectric layer 7 is not absorbing the coolant. Meanwhile, in order to facilitate the cladding of the liquid cooling pipe by the composite layer, connecting pieces 11 are arranged at two ends of the width direction of the composite layer, and as shown in fig. 2, the connecting pieces 11 at two ends of the width direction of the composite layer can be mutually matched to connect the composite layer to form a sleeve structure. For example, the connecting piece 11 may be a tape zipper or a velcro that is sewn on the upper and lower ends of the composite layer, and when the tape zipper or the velcro is adopted, the tape zipper and the velcro are respectively arranged to extend out of the composite layer, so that after the composite layer forms a sleeve structure through the connecting piece 11, only the connecting piece 11 is connected, and the conductive positive electrode layer 8 and the conductive negative electrode layer 6 on the upper and lower ends of the composite layer are not in direct contact.
In the above embodiment, the water-absorbing dielectric layer 7 may employ an insulating material layer such as a resin film layer capable of sufficiently absorbing water and water penetration, giving full play to its own insulating property and water-absorbing property; the conductive negative electrode layer 6 is preferably a conductive layer, such as a conductive carbon fiber film, a metal wire woven mesh, etc., which is hollow, and the conductive negative electrode layer 6 is provided with a hollow for facilitating the rapid flowing of the leaked cooling liquid 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 respectively provided with a convex wire welding area 12, so that the conductive positive electrode layer 8 and the conductive negative electrode layer 6 are conveniently connected by wires. The wire lands 12 of both the conductive positive electrode layer 8 and the conductive negative electrode layer 6 may be provided at opposite ends in the longitudinal direction.
Referring to fig. 3, in order to improve the reliability of the liquid leakage detecting device according to the preferred embodiment of the present invention, the composite layer further includes an inner water absorbing protective layer 10, and the inner water absorbing protective layer 10 is adhered to the inner side of the conductive negative electrode layer 6, where the inner side specifically refers to that the composite layer is coated on one side of the liquid cooling tube adhered to the outer periphery of the liquid cooling tube. By arranging the inner water absorption protective layer 10, the inner water absorption protective layer 10 is in direct contact with the liquid cooling pipe, and the conductive negative electrode layer 6 is arranged relative to the hollow part, so that the cooling liquid leaked from the pipe wall of the liquid cooling pipe is easier to be absorbed directly, and the cooling liquid is more uniformly permeated to the water absorption dielectric layer 7; meanwhile, the arrangement of the inner water absorption protective layer 10 increases the resistance between the conductive negative electrode layer 6 and the liquid cooling pipe, and electric leakage to the liquid cooling pipe is avoided when the liquid cooling pipe is a metal pipe and the conductive negative electrode layer 6 and the conductive positive electrode layer 8 are conducted.
Preferably, the composite layer further comprises an outer water-absorbing protective layer 9 arranged outside the conductive positive electrode layer 8, that is, when the composite layer is coated on the periphery of the liquid cooling tube, the outer water-absorbing protective layer 9 is located on the outermost layer of the sleeve structure. In general, the thickness of the outer water-absorbing protective layer 9 is the largest or the outer water-absorbing protective layer 9 can be multi-layered, so that the advantage of this arrangement is 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 the leaked cooling liquid, and a certain processing time is reserved for the operation and maintenance personnel from fault finding to fault removing, that is, the outer water-absorbing protective layer 9 plays a role of buffering; on the other hand, the outer water absorption protective layer 9 and the inner water absorption protective layer 10 are matched to absorb or isolate the water vapor in the air to a certain extent, so that the water vapor condensation at the pipe wall of the liquid cooling pipe is reduced, and the misjudgment of the liquid leakage detection device of the liquid cooling pipe caused by the inflation of the water absorption dielectric layer 7 by condensed water is avoided. When the composite layer is coated on the liquid cooling pipe, a plastic film can be coated on the outermost layer of the composite layer to further isolate water vapor.
In order to optimize the embodiment, improve the convenience of detection and discover 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. The alarm 5 can be a buzzer or an indicator lamp, and can be integrated with the controller 4, for example, the controller 4 and the alarm 5 adopt a computer, the computer is connected with the current detection unit 2, the current detection unit 2 transmits the detected current value to the computer in real time, and when the current value is not zero, the display interface is used for prompting the leakage of the liquid cooling tube. It should be noted that, in order to avoid the overlarge short-circuit current of the power module 1 when the conductive positive electrode layer 8 and the conductive negative electrode layer 6 are conducted, the power module 1 may be further connected with the protection resistor 3 in series or directly connected with the alarm 5 and the power module 1 in series as required, which is not described herein.
It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities. The current detection unit 2 in the present application does not only refer to an ammeter capable of detecting specific values of current, but also includes electric equipment or an electricity inspection device for indicating whether current exists.
The server liquid cooling pipe leakage detection device provided by the invention is described in detail above. The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
