[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution 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 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 are within the scope of protection of this application.

[0053] As the power consumption of servers increases, air cooling will not be able to meet the cooling needs in the future, and liquid cooling servers will be the general trend. At present, the cooling technology of liquid cooling servers is mainly divided into cold plate liquid cooling technology and immersion phase change liquid cooling.

[0054] Cold plate liquid cooling technology is an indirect liquid cooling technology. Its working principle is to fix the liquid that needs to dissipate heat on the cold plate. The liquid passes through the cold plate to transfer the heat of the equipment to achieve heat dissipation. At present, the cold plate module structure includes a liquid cold plate, a handle fixing seat, a handle and a locking structure, wherein the liquid cold plate is used to fix the central processing unit and dissipate heat for the central processing unit; the handle fixing seat is fixed on the liquid cold plate; the handle is connected to the handle fixing seats on two liquid cold plates among the multiple liquid cold plates; the locking structure passes through a part of the handle fixing seat and is embedded in the handle to lock the handle with the handle fixing seat.

[0055] However, the liquid cooling tubes in this traditional cold plate structure are relatively long, difficult to disassemble and assemble, and lack liquid collection and leakage detection, which can easily lead to damage to the machine when a large amount of leakage occurs.

[0056] To this end, the present application provides a cold plate structure and a server. By adopting a design in which a fixture assembly is set on the top of the cold plate assembly, and the cold plate assembly is placed on the circuit board using the fixture assembly, the cold plate assembly can be easily disassembled and assembled; a leakage detection line is used to detect the leakage of the cold plate structure to prevent excessive leakage and damage to the machine; a disassembly tool is used to separate the cold plate bottom plate from the circuit board to avoid chip damage during the disassembly process. Compared with the traditional cold plate structure, this structure is easy to disassemble and assemble, and the leakage of the cooling plate structure can be detected in real time to prevent damage to the machine.

[0057] A cold plate structure in this embodiment is further described below.

[0058] Figure 1 is a structural schematic diagram of a cold plate structure provided in an embodiment of the present application; Figure 2 It is a structural schematic diagram of a cold plate assembly in a cold plate structure provided in an embodiment of the present application; Figure 3 is an exploded view of a cold plate assembly in a cold plate structure provided in an embodiment of the present application; Figure 4 It is a structural schematic diagram of a fixture assembly in a cold plate structure provided in an embodiment of the present application; Figure 5 is a structural schematic diagram of a cooling unit in a cold plate structure provided in an embodiment of the present application; Figure 6 It is a structural schematic diagram of a cooling pipeline in a cold plate structure provided in an embodiment of the present application; Figure 7 It is a structural schematic diagram of a bracket in a cold plate structure provided in an embodiment of the present application.

[0059] like Figure 1As shown, the embodiment of the present application provides a cold plate structure 10, including a cold plate module 100, which is constructed to be fixed on a circuit board 200; the cold plate module 100 includes a cold plate assembly 110 and a fixture assembly 130, the cold plate assembly 110 includes a plurality of cold plate units 111, and the plurality of cold plate units 111 are arranged in parallel on the circuit board 200; a coolant flows through the cold plate units 111 to dissipate heat from the circuit board 200, and the cold plate units 111 have a first mounting hole; the fixture assembly 130 includes a mounting plate 131 and a plurality of connectors 132, the mounting plate 131 is suitable for people to take, the mounting plate 131 has a connecting portion, and the connecting portion has a plurality of second mounting holes; the second mounting holes and the first mounting holes are arranged correspondingly; the connector 132 is arranged in the corresponding second mounting hole, and is screwed into the first mounting hole to fix the mounting plate 131 with the plurality of cold plate units 111.

[0060] In this way, by adopting a design of setting a fixture assembly 130 on the top of the cold plate assembly 110, and using the fixture assembly 130 to place the cold plate assembly 110 on the circuit board 200, the cold plate assembly 110 is easier to disassemble and assemble; a leakage detection line 118 is used to detect the leakage of the cold plate structure to prevent excessive leakage and damage to the machine; a disassembly tool 137 is used to separate the cold plate bottom plate 112 from the circuit board 200 to avoid chip damage during the disassembly process. Compared with the traditional cold plate structure, this structure is easy to disassemble and assemble, and can detect the leakage of the cold plate structure in real time to prevent damage to the machine.

[0061] Among them, Figure 1 As shown, the cold plate assembly 110 is composed of a plurality of cold plate units 111 arranged according to a certain rule, and the cooling tube 115 is wound inside the plurality of cold plate units 111 to achieve cooling of the circuit board 200. However, the cooling tube 115 is mostly made of flexible materials. In order to facilitate the removal of the cold plate assembly 110 and prevent damage to the chip on the circuit board 200 when replacing the cold plate assembly 110, it is usually necessary for multiple people to work together, resulting in low work efficiency. To this end, this embodiment designs a fixture assembly 130 adapted to the cold plate assembly 110, which is used to support the cold plate assembly 110 and transfer the cold plate assembly 110 from the circuit board 200 to achieve the replacement operation.

[0062] When disassembling the cold plate assembly 110, the connector 132 is first used to screw the fixture assembly 130 into the internal threaded hole at the top of the cold plate assembly 110, and then the cold plate assembly 110 is transferred to the corresponding position of the circuit board 200 or removed from the circuit board 200. Specifically, after the disassembly is completed, the fixture assembly 130 can be placed on the top of the cold plate assembly 110, so that the fixture assembly 130 does not need to be installed when it is used next time, which reduces the operation steps and improves work efficiency; the fixture assembly 130 can also be taken out from the top of the cold plate assembly 110 and placed inside the machine room as an auxiliary tool for the next disassembly of the cold plate assembly 110, and the placement position of the fixture assembly 130 is not limited in this embodiment.

[0063] Among them, as an optional implementation, the type of the connecting member 132 is a hand screw. Specifically, the hand screw is connected and fixed to each cold plate base plate 112. After the fixture assembly 130 and the cold plate assembly 110 are assembled, the entire cold plate module 100 can be lifted by holding the first handle 135 on the fixture assembly 130 with one hand, which increases the convenience and safety of maintenance.

[0064] As an optional implementation, water can be selected as the coolant. The purpose of this setting is that water has good thermal conductivity, can quickly absorb and take away heat, and can ensure the purity and cleanliness of the coolant to avoid the influence of impurities and pollutants on the cold plate base.

[0065] In some embodiments, the connection portion includes two first connection portions 133 and at least two second connection portions 134 , and the two first connection portions 133 are spaced apart and arranged in parallel, the first connection portion 133 extends along the length direction of the mounting plate 131 , and the second connection portion 134 is spaced apart between the two first connection portions 133 .

[0066] Among them, an internal threaded hole is provided inside the connection part, and the connecting member 132 is screwed into the internal threaded hole to connect the cold plate assembly 110 with the fixture assembly 130. Specifically, a plurality of threaded holes are provided around the fixture assembly 130, so that when the arrangement of the cold plate unit 111 is changed, it can also be used, and has good applicability.

[0067] Among them, as an optional implementation, the edge of the jig assembly 130 can be designed with a telescopic structure. Specifically, when the length of the cold plate assembly 110 changes, the size of the jig assembly 130 can be changed by adjusting the telescopic structure of the edge of the jig assembly 130, which can be suitable for cold plate assemblies 110 of different sizes and specifications.

[0068] In some embodiments, the fixture assembly 130 includes a first handle 135 , which is fixedly disposed on a side of the mounting plate 131 that is away from the cold plate unit 111 .

[0069] Among them, Figure 4 As shown, friction layers are provided at both ends of the first handle 135, and the purpose of such provision is to increase friction and facilitate grasping of the cold plate assembly 110. Specifically, the first handle 135 is made of a lightweight material to reduce weight. In addition, the first handle 135 is small in size, which can reduce space occupancy and will not interfere with other components, thus facilitating the layout of the cold plate assembly 110.

[0070] In some embodiments, the fixture assembly 130 further includes an elastic buckle 136 and a disassembly tool 137 . The elastic buckle 136 is fixed to the mounting plate 131 , and the disassembly tool 137 is clamped in the elastic buckle 136 .

[0071] The elastic buckle 136 is provided with a slot inside, and the disassembly tool 137 is clamped in the elastic buckle 136 through the slot. Specifically, when the cold plate bottom plate 112 is disassembled, the disassembly tool 137 can be taken out from the elastic buckle 136.

[0072] In some embodiments, the cold plate unit 111 includes a cold plate bottom plate 112 and a second handle 113 ; the top of the second handle 113 is detachably connected to the mounting plate 131 , the second handle 113 is movably disposed on the cold plate bottom plate 112 , and the second handle 113 is detachably connected to the cold plate bottom plate 112 .

[0073] The second handle 113 is provided with a wire hole, and the cooling pipe 115 can pass through the wire hole, so that the cooling pipe 115 is regularly arranged on the cold plate bottom plate 112 to contact with the cold plate bottom plate 112, and prevent the cooling pipe 115 from being suspended above the cold plate bottom plate 112 and failing to cool the circuit board 200. Specifically, a groove is provided on the cold plate bottom plate 112 for collecting liquid leaking from the connection between the cooling pipe 115 and the diverter 122.

[0074] Among them, the second handle 113 is connected to the cold plate base plate 112 by a step screw. Specifically, the assembly of the step screw and the cold plate base plate 112 maintains a certain floating amount. The purpose of this setting is that since the fixture assembly 130 is used to fix and connect multiple cold plate base plates 112 and then assemble them onto the circuit board 200, the more cold plate base plates 112 there are, the greater the cumulative assembly tolerance is, and it is possible that some cold plates may not be assembled in place. Therefore, the cold plate base plate 112 and the second handle 113 are fixed by a step screw, and the assembly gap between the step screw and the second handle 113 is adjusted to create a floating amount between the second handle 113 and the cold plate base plate 112, so that it can be ensured that each cold plate base plate 112 of the cold plate module 100 is assembled in place.

[0075] In some embodiments, a notch 114 is provided at the edge of the cold plate bottom plate 112 , and the shape of the notch 114 matches the port shape of the disassembly tool 137 . The disassembly tool 137 is configured to pry the cold plate bottom plate 112 off the circuit board 200 when inserted into the notch 114 .

[0076] In order to overcome the problem that the cold plate bottom plate 112 is difficult to disassemble due to thermal conductive materials, especially phase change materials, this embodiment uses a principle similar to a crowbar. When in use, one end of the cold plate disassembly tool is inserted into the notch 114 of the cold plate bottom plate 112, and the other end of the disassembly tool 137 is pried to lift the cold plate bottom plate 112, thereby achieving the purpose of separating the cold plate bottom plate 112 from the chip on the circuit board 200.

[0077] In some embodiments, the cold plate unit 111 further includes a cooling pipe 115 and a water tank, the cooling pipe 115 includes a water inlet pipe 116 and a water outlet pipe 117, and the water inlet pipe 116 and the water outlet pipe 117 are respectively connected to the water tank to form a circulation loop;

[0078] The water inlet pipe 116 contacts the cold plate bottom plate 112 so that the coolant in the cooling pipe 115 exchanges heat with the cold plate bottom plate 112 ; the water outlet pipe 117 is configured to recover the coolant after heat transfer with the cold plate bottom plate 112 into the water tank.

[0079] Among them, Figure 6 As shown, a clamp is provided on the cooling pipe 115 to ensure the tightness of the connection between the cooling pipe 115 and the cold plate unit 111 to avoid leakage. Specifically, a quick-release joint is provided at one end of the cooling pipe 115 away from the cold plate assembly 110, so as to facilitate disassembly and speed up installation.

[0080] In some embodiments, the cold plate assembly 110 includes a leakage detection device, which includes a leakage detection controller and a leakage detection line 118. The leakage detection line 118 is wound around the circumference of the outer edge of the cooling tube 115. The leakage detection controller is connected to the leakage detection line 118 and provides current to the leakage detection line to determine the leakage state according to the resistance change of the leakage detection line 118.

[0081] Among them, as an optional implementation, the leakage detection line 118 is a positioning leakage detection line. Specifically, once a leakage occurs in the positioning detection cable, it can not only immediately issue an alarm, but also accurately display the distance where the leakage occurs, with an error range of no more than 0.5m. The positioning leakage detection line 118 is mainly composed of a positioning leakage controller, a positioning leakage rope, and a lead-out line. The structure of the positioning leakage sensing line is composed of two sensor lines and two signal transmission lines. When water is immersed between the two sensor lines, a leakage can be detected. The two signal transmission lines can accurately determine the location of the leakage through changes in resistance. After the signal is transmitted to the leakage controller, the location of the leakage point can be accurately viewed on its display screen.

[0082] The cold plate bottom plate 112 is provided with a plastic spring and a groove, and the purpose of providing the plastic spring is to limit and fix the liquid detection line 118, and to fit the liquid detection line 118 to the bottom of the groove, so that when leakage occurs, the liquid detection line 118 can detect it as quickly as possible. Specifically, a pagoda head is also provided at the bottom of the groove to fix the cooling pipe 115.

[0083] In some embodiments, the cold plate unit 111 includes a diverter assembly 120, and the diverter assembly 120 includes a bracket 121 and a diverter 122; the diverter 122 is provided with a plurality of connectors, and the plurality of connectors are connected to the cooling pipe 115, and is configured to divert the liquid inside the cooling pipe 115;

[0084] The diverter 122 and the second handle 113 are both disposed on a bracket 121, and the bracket 121 is configured to fix the diverter 122 to the second handle 113, wherein the bracket 121 is fixed to the second handle 113 by screws 123.

[0085] Among them, a pagoda head is arranged on the diverter 122, the main purpose of which is to divide the water flow of the water inlet pipe 116 into multiple water pipes, or to gather the water flows of multiple water pipes of the water outlet pipe 117 into one water pipe.

[0086] In the present embodiment, a cold plate structure 10 includes a cold plate module 100, which is configured to be fixed on a circuit board 200; the cold plate module 100 includes a cold plate assembly 110 and a fixture assembly 130, the cold plate assembly 110 includes a plurality of cold plate units 111, and the plurality of cold plate units 111 are arranged in parallel on the circuit board 200; a coolant flows through the cold plate units 111 to dissipate heat from the circuit board 200, and the cold plate units 111 have a first mounting hole; the fixture assembly 130 includes a mounting plate 131 and a plurality of connectors 132, the mounting plate 131 is suitable for people to take, the mounting plate 131 has a connecting portion, and the connecting portion has a plurality of second mounting holes; the second mounting holes and the first mounting holes are arranged correspondingly; the connector 132 is arranged in the corresponding second mounting hole and is screwed into the first mounting hole to fixedly connect the mounting plate 131 with the plurality of cold plate units 111. In this way, by adopting a design of setting a fixture assembly 130 on the top of the cold plate assembly 110, and using the fixture assembly 130 to place the cold plate assembly 110 on the circuit board 200, the cold plate assembly 110 is easier to disassemble and assemble; a leakage detection line 118 is used to detect the leakage of the cold plate structure to prevent excessive leakage and damage to the machine; a disassembly tool 137 is used to separate the cold plate bottom plate 112 from the circuit board 200 to avoid chip damage during the disassembly process.
