[0046] As described in the background technology, the liquid cooling equipment in the related art is prone to refrigerant leakage, which reduces the safety of the server. The inventors have found that the reason for this problem is that the liquid cooling equipment in the related art usually includes a chip liquid cooling plate and a liquid distributor, wherein the liquid distributor has a liquid inlet joint and a liquid outlet joint, and the liquid inlet joint and the liquid outlet joint are connected to the liquid inlet and liquid outlet of the chip liquid cooling plate to ensure that the refrigerant can flow in the chip liquid cooling plate, thereby taking away the heat generated by the server. However, the liquid inlet joint and the liquid inlet and / or the liquid outlet joint and the liquid outlet may become loose or separated, causing the refrigerant to overflow the liquid distributor and the chip liquid cooling plate, and then the refrigerant flows to the electronic components of the server, causing damage to the electronic components, thereby reducing the safety and service life of the server.

[0047] In response to the above technical problems, the embodiments of the present application provide a liquid cooling device and a server. By setting the liquid distributor in the box, when the liquid inlet joint and the liquid inlet and / or the liquid outlet joint and the liquid outlet become loose or separated, the overflowed refrigerant can be collected by the box, so as to prevent the overflowed refrigerant from flowing to the electronic components of the server, thereby improving the safety and service life of the server. In addition, the liquid cooling device also includes a first detection component, wherein the first detection component includes a detection part and a processor, and the detection end of the detection part is located on the side of the liquid distributor close to the bottom wall of the box and is arranged close to the bottom wall of the box; the processor is used to be arranged on the main board of the server and connected to the detection part, and the processor is used to judge whether there is refrigerant in the box according to the detection signal of the detection part, so as to remind the staff to deal with it in time, thereby improving the safety of the server.

[0048] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0049] Please refer to the attached Figure 1 To Attachment Fig. 9 The embodiment of the present application provides a liquid cooling device, which is used to quickly dissipate heat and cool down a PCle chip. The liquid cooling device includes a housing 100, a chip liquid cooling plate 200, a liquid distributor 300, and a first detection component. It should be noted that the chip liquid cooling plate 200 can be understood as a component formed by integrating a chip into a liquid cooling plate, wherein the chip can be a PCle chip.

[0050] Please refer to the attached Figure 2 and attached Figure 3 The housing 100 includes a receiving chamber 110, and the receiving chamber 110 is used to receive some components of the liquid cooling device, for example, for receiving the liquid dispenser 300 and part of the first detection component. The housing 100 may include a bottom plate 120 and a side plate 130 arranged around the bottom plate 120, and the bottom plate 120 and the side plate 130 are arranged to form a receiving chamber with a top opening, so that the liquid dispenser 300 can be installed in the receiving chamber 110 through the top opening. It should be understood that the side plate 130 includes a first side plate, a second side plate, a third side plate and a fourth side plate connected in sequence; the first side plate and the third side plate are arranged opposite to each other, and the second side plate and the fourth side plate are arranged opposite to each other; Figure 3 Taking the orientation shown as an example, the first side panel and the third side panel are respectively the left side panel and the right side panel of the box body 100, and the second side panel and the fourth side panel are respectively the front side panel and the rear side panel of the box body 100. Among them, the first side panel, the second side panel, the third side panel and the fourth side panel can be integrally formed or can be a separate structure. When the side panel 130 is an integral part, the structural strength of the box body 100 can be improved, thereby improving the stability of the box body 100.

[0051] Please refer to the attached Figure 1 and attached Figure 2 The liquid distributor 300 is disposed in the accommodating chamber 110. For example, the liquid distributor 300 can be fixedly connected to the side plate 130 by screws, or the liquid distributor 300 can be fixedly connected to the first side plate and the third side plate by screws. It should be noted that there is a gap between the bottom surface of the liquid distributor 300 and the bottom plate 120 of the box body 100, which can be used to accommodate the overflowed refrigerant and set the detection end of the first detection component.

[0052] Please refer to the attached Figure 6 The liquid distributor 300 includes a liquid inlet connector 310 and a liquid outlet connector 320, which are respectively plugged into the liquid inlet and liquid outlet of the chip liquid cooling plate 200 to achieve connectivity between the liquid distributor 300 and the chip liquid cooling plate 200, thereby ensuring that the refrigerant circulates in the chip liquid cooling plate 200, thereby cooling the chip integrated on the chip liquid cooling plate 200.

[0053] In this embodiment, the liquid distributor 300 may be a pipeline, or other options may be provided. Figure 4 The liquid distributor 300 includes a circulation tube 330 and two blocking members 340. The two blocking members 340 are respectively arranged at both ends of the circulation tube 330 to block the circulation tube 330 to prevent the refrigerant from overflowing the liquid distributor 300. The liquid inlet connector 310 and the liquid outlet connector 320 are arranged on the circulation tube 330 and are interconnected with the inner cavity of the circulation tube 330. The blocking members 340 can be fixedly connected to the side plate 130 by screws. For example, one of the blocking members 340 is fixedly connected to the first side plate by screws, and the other blocking member 340 is fixedly connected to the third side plate by screws.

[0054] It should be understood that there are multiple chip liquid cooling plates 200 in the server, so the number of liquid inlet connectors 310 and liquid outlet connectors 320 can match the number of chip liquid cooling plates 200 so that refrigerant can circulate in each chip liquid cooling plate 200.

[0055] In this embodiment, the liquid distributor 300 is disposed in the accommodating cavity 110 of the housing 100. When the liquid inlet connector 310 and the liquid inlet port and / or the liquid outlet connector 320 and the liquid outlet port become loose or separated, the overflowed refrigerant can be collected by the housing 100, thereby preventing the overflowed refrigerant from flowing to the electronic components of the server, thereby improving the safety and service life of the server.

[0056] Please refer to the attached Figure 2 The first detection component includes a detection member 400 and a processor (not shown in the figure). The detection end of the detection member 400 is located on the side of the liquid dispenser 300 close to the bottom wall of the box 100 and is arranged close to the bottom wall of the box 100. The processor is used to be arranged on the main board of the server and connected to the detection member 400. The processor is used to determine whether there is refrigerant in the box 100 according to the detection signal of the detection member 400. If the processor determines that there is refrigerant, an alarm prompt can be issued.

[0057] In this embodiment, the detection end of the detection member 400 is located on a side of the liquid dispenser 300 close to the bottom wall of the box 100 and is arranged close to the bottom wall of the box 100, so that the detection member 400 can detect whether there is refrigerant in the box 100 as soon as possible. The processor is used to determine whether there is refrigerant in the box according to the detection signal of the detection member, and issue an alarm prompt to remind the staff to handle it in time, thereby improving the safety of the server.

[0058] It should be noted that the detection element in this embodiment may be a liquid level sensor, or may have other structures. Figure 2 The detection member 400 includes a first connection cable, which is disposed in the accommodating cavity 110 and close to the bottom wall of the box 100; wherein the first connection cable can be fixed to the side panel of the box 100 by a buckle, for example, the first connection cable can be fixed to the fourth side panel of the box 100 by a buckle. The first connection cable can also be connected to the fourth side panel in other ways. For example, please continue to refer to the attached Figure 2 , a plurality of connecting posts are also provided on the inner wall of the box 100. For example, a plurality of connecting posts 140 are provided on the inner wall of the fourth side plate of the box 100. The plurality of connecting posts 140 are arranged at intervals on the inner wall of the fourth side plate. It should be noted that the number of the plurality of connecting posts 140 in this embodiment can be set according to the size of the box 100 and the first connecting cable. Exemplarily, the number of the connecting posts 140 in this embodiment is seven, and the distances between adjacent connecting posts 140 can be equal or unequal.

[0059] The first connecting cable surrounds any connecting column 140, and the connecting column 140 is used to achieve fixed connection of the first connecting cable, which has the advantages of simple structure and convenient operation. It should be noted that the bottom surface of the dispenser 300 provided in this example can also be pressed against the top surface of the connecting column 140 to prevent the first connecting cable from loosening, thereby ensuring that the first connecting cable can be close to the bottom wall of the box 100.

[0060] The two ends of the first connecting cable are respectively located outside the box 100 and connected to the processor. There are many ways to connect the first connecting cable to the processor. For example, the two ends of the first connecting cable can be directly welded to the motherboard, and then connected to the processor through the circuit set in the motherboard. The first connecting cable can also be connected to the processor in other ways. In another example, please refer to the attached Figure 7 Both ends of the first connecting cable are connected to the connector 540 disposed on the mainboard 500 through the connecting connector, and then connected to the processor through the connector 540 and the circuit disposed in the mainboard 500.

[0061] The processor is used to determine whether there is refrigerant in the box 100 according to the resistance value of the first connecting cable. When the first connecting cable is immersed in the refrigerant, the resistance of the first connecting cable will change, for example, the resistance of the first connecting cable will increase, and the processor can detect the change of the resistance of the first connecting cable in time, and then issue an alarm prompt in time and effectively.

[0062] Please refer to the attached Figure 2 and attached Figure 3 The box body 100 includes a first avoidance gap 150, which is arranged on the wall surface where the first connecting cable is located, and is used for the first connecting cable to pass through. For example, when the first connecting cable is arranged on the inner wall surface of the fourth side plate, the first avoidance gap 150 is correspondingly arranged on the fourth side plate, and the first avoidance gap 150 penetrates the fourth side plate along the thickness of the fourth side plate and exposes the top surface of the fourth side plate, so that the first avoidance gap 150 is a U-shaped structure.

[0063] With such arrangement, when the first connecting cable extends to the outside of the box body 100 through the first avoidance gap 150 , the first connecting cable is prevented from contacting the chip liquid cooling plate 200 arranged thereon, thereby reducing wear on the first connecting cable.

[0064] In one possible implementation, please refer to the attached Figure 1 To Attachment Figure 4 The liquid distributor 300 further includes a liquid inlet manifold 350 and a liquid outlet manifold 360 , both of which are connected to the inner cavity of the circulation tube 330 to ensure that the refrigerant can circulate in the liquid distributor 300 .

[0065] The inlet manifold 350 is disposed on the side of the circulation tube 330 and extends in a direction perpendicular to the circulation tube 330, and the outlet manifold 360 is disposed on the top surface of the circulation tube 330 and extends in a direction perpendicular to the circulation tube 330; in view of this, the box body 100 is provided with a second avoidance notch 160 for avoiding the inlet manifold 350, so as to facilitate the installation of the inlet manifold 350 and reduce the wear on the inlet manifold 350. The shape of the second avoidance notch 160 can be the same as that of the first avoidance notch 150, and this embodiment will not be described in detail here.

[0066] The refrigerant enters the flow pipe 330 of the liquid distributor 300 through the liquid inlet main pipe 350, and then enters the chip liquid cooling plate 200 through the corresponding liquid inlet joint 310 to dissipate heat and cool the chip; after absorbing the heat, the refrigerant enters the flow pipe 330 of the liquid distributor 300 through the liquid outlet and the liquid outlet joint 320, and is finally discharged to the outside of the liquid cooling device through the liquid outlet main pipe 360.

[0067] In one possible implementation, please refer to the attached Figure 2 and attached Figure 3 The liquid distributor 300 further includes a plug connector 370 connected to the inner cavity of the circulation tube 330, wherein the plug connector 370 can be connected to the liquid cooling plate of other heating units to dissipate heat for other heating units.

[0068] In this embodiment, the plug connector 370 extends in a direction perpendicular to the side wall of the box 100 and extends to the outside of the box 100. In view of this, the box 100 provided in this embodiment further includes an extension section 170, which extends in a direction perpendicular to the side wall of the box so that the extension section 170 protrudes from the box 100.

[0069] Among them, the extension section 170 is provided with a collection groove 171 opposite to the plug-in connector 370, and the collection groove 171 is located on the side of the plug-in connector 370 close to the bottom wall of the box body 100, that is, the collection groove 171 is located directly below the plug-in connector 370, and is used to collect the refrigerant leaked from the plug-in connector 370, thereby further improving the safety of the server.

[0070] Please refer to the attached Figure 3 In the width direction of the box body 100, the bottom plate 120 protrudes from the side plates 130, and a plurality of reinforcing plates 180 are arranged on the protruding portion of the bottom plate 120, and the reinforcing plates 180 are also connected to the side plates 130. With such an arrangement, the box body 100 can be connected to the chassis of the server by means of captive screws, so as to facilitate the installation of the box body 100; in addition, the arrangement of the reinforcing plates 180 can also improve the structural strength of the box body 100 and enhance the carrying capacity of the box body 100.

[0071] Please refer to the attached Figure 1 , Attachment Figure 2 And attached Figure 5 To Attachment Fig. 9 , an embodiment of the present application also provides a server, which can be applied to a data processing center.

[0072] The server includes a mainboard 500, a chassis 600, and the liquid cooling device described in the first aspect. Figure 5 and attached Figure 6 The chassis 600 is used to carry the motherboard 500 and the liquid cooling device. For example, the liquid cooling device case 100 can be fixed to the chassis 600 by captive screws; the motherboard 500 can also be fixed to the chassis 600 by screws and located on one side of the case 100.

[0073] A slot 510 is provided on the mainboard 500. When the housing of the liquid cooling device is installed to the chassis, the gold finger of the chip liquid cooling plate 200 is inserted into the slot 510 to realize electrical connection between the chip integrated on the chip liquid cooling plate 200 and the mainboard 500.

[0074] In view of the fact that the liquid cooling device in this embodiment includes a box 100, when the liquid inlet joint 310 and the liquid inlet and / or the liquid outlet joint 320 and the liquid outlet are loosened or separated, the overflowed refrigerant can be collected by the box 100 to prevent the overflowed refrigerant from flowing to the electronic components of the server, thereby improving the safety and service life of the server. At the same time, the liquid cooling device also includes a detection member 400, which is connected to the processor of the mainboard 500, and the detection end of the detection member 400 is located on the side of the liquid distributor 300 close to the bottom wall of the box 100 and is arranged close to the bottom wall of the box 100, so that the detection member 400 can detect whether there is refrigerant in the box 100 as soon as possible. The processor is used to determine whether there is refrigerant in the box according to the detection signal of the detection member, and issue an alarm prompt to remind the staff to handle it in time, thereby improving the safety of the server.

[0075] In a possible implementation, the server further includes a second detection component, which is used to detect whether the connector of the liquid dispenser 300 is inserted into place with the chip liquid cooling plate 200. For example, the second detection component is used to detect whether the liquid outlet connector 320 of the liquid dispenser 300 is inserted into place with the liquid outlet of the chip liquid cooling plate 200, and to detect whether the liquid inlet connector 310 of the liquid dispenser 300 is inserted into place with the liquid inlet of the chip liquid cooling plate 200.

[0076] Please refer to the attached Fig. 9 , wherein the second detection component includes a conduction switch 700 set in the liquid cooling device and a detection circuit set in the mainboard 500, wherein the conduction switch 700 includes an on state and an off state; an indicator light 520 and a switching transistor 530 are connected in series in the detection circuit; and a gate of the switching transistor 530 is connected to the conduction switch 700.

[0077] When the connector of the dispenser 300 is inserted into the chip liquid cooling plate 200, the conduction switch 700 is turned on and the switch transistor 530 is controlled to be turned on, so that the indicator light 520 located in the detection circuit is in a light-emitting state. If the connector of the dispenser 300 is not inserted into the chip liquid cooling plate 200, the corresponding indicator light 520 is not lit. In this way, by using the light or no light of the indicator light 520, it can be better and more clearly known whether the connector of the dispenser 300 and the chip liquid cooling plate 200 are inserted into the right place, which is convenient for the staff to check and repair in time, avoid the refrigerant from the connection between the dispenser 300 and the chip liquid cooling plate 200. Overflow, and then avoid the overflowed refrigerant from flowing to the electronic components of the server, thereby improving the safety of the server.

[0078] In this embodiment, please refer to the attached Figure 8, the conduction switch 700 includes a shell 710, a movable column 720, and a conduction member (not shown in the figure) disposed in the shell 710; the movable column 720 can be slidably disposed on the shell 710 and move along the bottom wall direction perpendicular to the shell 710. When the chip liquid cooling plate 200 is installed in the slot 510, the chip liquid cooling plate 200 will contact the movable column 720 and drive the movable column 720 to move in the direction toward the bottom wall of the shell 710, so that the movable column 720 is connected to the conduction member, so that the conduction switch 700 is in a conduction state; when the movable column 720 is not in contact with the conduction member, the conduction switch 700 is in an off state. It should be noted that the conduction member can be a knife switch or two conductive contacts.

[0079] The conduction switch 700 is mounted on the box 100. Exemplarily, the housing 710 includes at least one protrusion 730, and correspondingly, the box 100 is provided with a connection hole, and the housing 710 can be mounted on the box 100 by bolts.

[0080] In a possible implementation, there are multiple second detection components and chip liquid cooling plates 200 that correspond to each other; that is, one second detection component is used to detect whether the corresponding chip liquid cooling plate 200 is installed in place.

[0081] Please refer to the attached Figure 2 and attached Figure 5 To Attachment Figure 7 , multiple conduction switches 700 are respectively connected to the first switch connector 800 through the second connecting cable 810; multiple detection circuits are respectively connected to the second switch connector 900, and the second switch connector 900 is connected to the first switch connector 800 to form a second detection component for independently detecting whether each chip liquid cooling plate 200 is installed in place. In this way, multiple second detection components are connected in parallel and independently of each other, and can detect whether each chip liquid cooling plate 200 is installed in place.
