[0002] With the rapid development of cloud computing, the requirements for computing performance are getting higher and higher. While the performance of servers has been improved, the power consumption has shown a rapid upward trend. The power consumption of cabinets has increased exponentially, and the cooling capacity of the air-cooling method of air conditioners is also approaching its limit and cannot meet the cooling requirements. Therefore, liquid cooling technology has emerged. The advantage of liquid cooling technology lies in that the specific heat capacity and thermal conductivity of its heat transfer medium are higher, and it can better solve the thermal management of battery systems than air cooling. The working mode of liquid cooling is to immerse heat exchange equipment such as servers that need to be cooled in the insulating coolant in the cabinet, and use the circulating flow of the coolant to achieve heat dissipation.

The examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Based on the embodiments in the embodiments, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0025] The phrase "in one embodiment" as used in this specification does not necessarily refer to the same embodiment when it appears in various positions in the specification.

[0026] Embodiment:

[0027] Such as Figures 1 to 3As shown, this embodiment provides a liquid-cooled cabinet, including a shell 1 filled with cooling liquid and at least one electronic information device 2 arranged in the shell 1. The liquid-cooled cabinet also includes a lifting platform 11 and a driving mechanism 12 arranged in the shell 1, and the lifting platform 11 carries the electronic information device 2; the shell 1 is provided with an opening 13, and the driving mechanism 12 drives the lifting platform 11 to move so that the electronic information device 2 is close to or away from the opening 13.

[0028] In this embodiment, a liquid-cooled cabinet is provided, which includes a shell 1 and an electronic information device 2 (such as a server) stored in the shell 1. The shell 1 is filled with coolant, and the electronic information device 2 is immersed in the coolant. The flow of the coolant can absorb and take away the heat generated by the electronic information device 2 during operation, so that the device maintains a low operating temperature, prolongs its service life, and improves operating stability. The shell 1 is also provided with a lifting platform 11 for carrying the electronic information device 2 and a driving mechanism 12 for driving the lifting platform 11 to move, that is, the driving mechanism 12 can drive the lifting platform 11 carrying the electronic information device 2 to move. In addition, an opening 13 opposite to the bottom wall of the shell 1 is formed at the end of the shell 1. The driving mechanism 12 can drive the lifting platform 11 to move so that the electronic information device 2 is close to or away from the opening 13, so that the electronic information device 2 can be easily taken in and maintained through the opening 13, without relying on an external operation and maintenance vehicle, which significantly improves the installation and maintenance efficiency of the electronic information device 2 and simplifies the maintenance operation process of the electronic information device 2.

[0029] In the related art, when electronic information equipment 2 such as servers needs to be maintained, the cabinet usually needs to be lifted and taken out with the help of an operation and maintenance vehicle, but the operation steps for lifting using an operation and maintenance vehicle are relatively complicated, and it is inconvenient to take and place the electronic information equipment 2 without an operation and maintenance vehicle. 2 In this embodiment, a lifting platform 11 and a drive mechanism 12 are arranged in the cabinet shell 1 to realize automatic lifting of the electronic information equipment 2, without relying on heavy equipment such as external operation and maintenance vehicles, and also avoiding the safety risks generated during the lifting process of the operation and maintenance vehicle, and reducing maintenance costs.

[0030] In addition, a retractable support frame can be set on the top surface of the lifting platform 11, and the electronic information equipment 2 can be placed on the support frame. After the electronic information equipment 2 is lifted by the lifting platform 11, it can also be moved to the outside of the cabinet by the support frame, thereby improving the convenience and efficiency of maintenance, replacement or upgrading of the electronic information equipment 2.

[0031] like Figure 2 and Figure 3As shown, the driving mechanism 12 includes a lead screw 121 and a slider 122 sleeved on the lead screw 121. The lead screw 121 extends towards the opening 13 along the height direction of the housing 1; the slider 122 is formed with an internal thread, and the surface of the lead screw 121 is formed with an external thread that mates with the internal thread so that the slider 122 moves up and down along the lead screw 121, and the slider 122 is fixedly connected to the lifting platform 11.

[0032] In this embodiment, the driving mechanism 12 includes a lead screw 121 and a slider 122 sleeved on the lead screw 121. The lead screw 121 extends from the bottom of the housing 1 along the height direction of the housing 1 until it approaches or reaches the opening 13 of the housing 1. An internal thread is formed inside the slider 122, and an external thread matching the internal thread is machined on the outer surface of the lead screw 121. When the lead screw 121 rotates, due to the meshing of the internal thread and the external thread, the slider 122 will move up and down along the length direction of the lead screw 121 (i.e., the height direction of the housing 1). At the same time, the lifting platform 11 is fixedly connected to the slider 122. When the slider 122 moves up and down, it will drive the entire lifting platform 11 and the electronic information device 2 carried thereon to move up and down synchronously. In other embodiments, the driving mechanism 12 can also be other structures that can realize the lifting of the lifting platform 11, such as a hydraulic cylinder, which drives the lifting platform 11 to lift through the piston in the hydraulic cylinder, or an electric push rod, which realizes the lifting movement of the push rod by controlling the forward and reverse rotation of the motor, and then drives the lifting platform 11 to lift. Therefore, the structure of the driving mechanism 12 in this application is not limited to the cooperation between the lead screw 121 and the slider 122, and the structures of other driving mechanisms 12 that can realize the lifting of the lifting platform 11 should also be covered within the scope of protection required by this application.

[0033] The lifting platform 11 includes a bracket 111 composed of main beams 1111 and secondary beams 1112 intersecting with the main beams 1111. The driving mechanism 12 further includes a cover plate 15 provided with a guide groove 151. The guide groove 151 extends towards the opening 13, and the end of the main beam 1111 passes through the guide groove 151 so that the bracket 111 moves along the guide groove 151.

[0034] In this embodiment, a plurality of main beams 1111 and a plurality of secondary beams 1112 intersect and are fixedly connected to form a stable frame structure, forming a bracket 111 for carrying the electronic information device 2. The bracket 111 can disperse and bear the weight and force from the electronic information device 2, so that the lifting platform 11 can remain stable when carrying the electronic information device 2 and is not easily deformed or damaged. In addition, the bracket 111 can not only provide a bearing function, but also serve as a connection point between the lifting platform 11 and the driving mechanism 12. Specifically, the driving mechanism 12 includes a cover plate 15 with a guide groove 151, and the guide groove 151 can guide the movement of the lifting platform 11. The shape and size of the guide groove 151 match the structure of the end of the main beam 1111, so that the end of the main beam 1111 can smoothly pass through the guide groove 151 and move inside it. The extension direction of the guide groove 151 determines the moving direction of the lifting platform 11, that is, it extends toward the opening 13 of the cabinet. The guide groove 151 can ensure that the lifting platform 11 can move smoothly along the predetermined path, avoiding errors and accidents caused by deviation or shaking. Specifically, in this embodiment, the bracket 111 includes two main beams 1111 and four sub-beams 1112 arranged between the two main beams 1111, and the sub-beams 1112 are arranged perpendicular to the main beams 1111. In other embodiments, the main beams 1111 and the sub-beams 1112 can also be other combinations of numbers, and the angle between the two can also be 30° or 50°, etc., which is not limited here.

[0035] The bracket 111 includes two main beams 1111 arranged in parallel. Both ends of each main beam 1111 are fixedly connected with a slider 122 . The screw rods 121 correspond to the sliders 122 one by one.

[0036] In this embodiment, the bracket 111 is roughly constructed as a rectangular structure, two main beams 1111 are arranged in parallel, and sliders 122 are fixedly connected to both ends of each main beam 1111, the screw rods 121 correspond to the sliders 122 one by one, and each screw rod 121 is provided with a slider 122, that is, there are four groups of screw rods 121 and sliders 122 in the shell 1, and the four groups of screw rods 121 and sliders 122 are respectively arranged at the four end corners of the bracket 111, so that the bracket 111 is subjected to more uniform force, and each corner bears part of the weight and reaction force during the lifting process, thereby reducing the distortion and deformation of the bracket 111 and improving the stability of the lifting process.

[0037] The lifting platform 11 includes a tray 112 disposed on a bracket 111 . The electronic information device 2 is placed on the tray 112 . The tray 112 is provided with a plurality of liquid leakage holes 1121 .

[0038] In this embodiment, a tray 112 with dimensions close to those of the bracket 111 is further provided on the bracket 111. The tray 112 is provided with a plurality of liquid leakage holes 1121. During the lifting process of the lifting platform 11, the coolant can freely enter and exit through the liquid leakage holes 1121, reducing the impact of the coolant on the lifting operation of the lifting platform 11. When the lifting platform 11 is lifted or lowered, if there are no liquid leakage holes 1121 on the tray 112, the coolant will become a resistance to the rising or falling of the tray 112, thereby affecting the stability and lifting accuracy of the lifting platform 11.

[0039] As Figure 3 and Figure 4 shown, the driving mechanism 12 includes a driving motor 123 and a transmission shaft assembly 124 connected to the output shaft 1231 of the driving motor 123. The transmission shaft assembly 124 includes a driving shaft 1241 and a driven shaft 1242 linked to the driving shaft 1241, and the driven shaft 1242 is linked to the lifting platform 11.

[0040] In this embodiment, the driving mechanism 12 includes a driving motor 123 and a transmission shaft. The power output by the driving motor 123 is transmitted through the transmission shaft assembly 124, and finally the lifting or movement of the lifting platform 11 is realized. Specifically, the output shaft 1231 of the driving motor 123 is connected with two driving shafts 1241 through a three-way coupling. A transmission gear for transmitting power is arranged inside the three-way coupling. Under the action of the three-way coupling, the rotation of the output shaft 1231 can drive the rotation of the driving shaft 1241. Then each driving shaft 1241 is connected with two driven shafts 1242 through a three-way coupling, and each driven shaft 1242 is linked to a lead screw 121 through a gear set to transmit power to the lead screw 121 and drive the lead screw 121 to rotate. In other embodiments, the transmission shaft assemblies 124, between the transmission shaft assembly 124 and the output shaft 1231 of the driving motor 123, or between the transmission shaft assembly 124 and the lead screw 121 can also be transmitted by means such as chain drive and belt drive, which are not limited here.

[0041] A partition 14 is installed inside the housing 1, and the transmission shaft assembly 124 is accommodated between the partition 14 and the bottom wall of the housing 1.

[0042] In this embodiment, by installing the partition 14 inside the housing 1, the vertical space inside the housing 1 can be utilized to accommodate the transmission shaft assembly 124 in a relatively enclosed and orderly space, reducing the space occupied by the entire device and making the internal layout more compact and reasonable. In addition, the partition 14 provides an additional protective layer for the transmission shaft assembly 124, reducing the direct impact and damage of external factors on the transmission shaft assembly 124.

[0043] The drive motor 123 is disposed outside the housing 1. The housing 1 is provided with a mounting hole, and the output shaft 1231 of the drive motor 123 extends into the housing 1 through the mounting hole. An oil seal is installed in the gap between the output shaft 1231 of the drive motor 123 and the mounting hole.

[0044] In this embodiment, the drive motor 123 is disposed outside the housing 1, and the housing 1 is provided with a mounting hole to enable the output shaft 1231 of the drive motor 123 to extend into the housing 1 and be connected to the transmission shaft assembly 124. In order to improve the sealing performance of the housing 1, prevent the leakage of lubricating oil or other liquids, and reduce the intrusion of dust and impurities while the drive motor 123 is working, an oil seal is installed in the gap between the mounting hole and the output shaft 1231 of the drive motor 123.

[0045] The liquid-cooled cabinet includes a liquid inlet 16 and a liquid outlet 17 that are both communicated with the inside of the housing 1. The liquid inlet 16 and the liquid outlet 17 are respectively disposed on opposite side walls of the housing 1.

[0046] In this embodiment, the liquid inlet 16 and the liquid outlet 17 are respectively disposed on opposite sides of the housing 1, so that the coolant forms a relatively uniform flow path inside the cabinet, and the heat in each area inside the cabinet can be taken away, thereby improving the heat dissipation effect. When it is necessary to clean or replace the coolant, the connection pipelines of the liquid inlet 16 and the liquid outlet 17 can be conveniently connected or disconnected.

[0047] A baffle 18 is disposed inside the housing 1. The baffle 18 and the side wall of the housing 1 enclose an overflow chamber 19, and the overflow chamber 19 is provided with a liquid outlet 17.

[0048] In this embodiment, the baffle 18 and the side wall of the housing 1 cooperate to define a specific space as the overflow chamber 19. The liquid inlet 16 continuously supplies coolant to the inside of the housing 1. The relatively hot coolant after heat exchange floats upward, and the overflow chamber 19 is used to collect the high-temperature coolant exceeding the height of the opening 13 of the overflow chamber 19, and then quickly discharge the excess coolant through the liquid outlet 17 of the overflow chamber 19 to prevent excessive pressure inside the cabinet or coolant overflow.

[0049] In this embodiment, a liquid retaining block is further disposed on the side wall of the housing 1. The liquid retaining block can reduce the space inside the housing 1, and thus reduce the amount of coolant used. Specifically, the upper end of the lead screw 121 is fixed to the surface of the liquid retaining block.

[0050] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
