[0001] The invention relates to the technical field of liquid cooling cabinets, and in particular to an immersion liquid cooling cabinet. Background Art

[0002] Liquid-cooled cabinets are cabinets that use liquid as a cooling medium. Among them, immersion-type liquid-cooled cabinets are an efficient data center cooling solution that completely or partially immerses IT equipment such as servers in non-conductive liquids, using the high thermal capacity and excellent heat transfer properties of liquids to effectively transfer heat and achieve the purpose of cooling. This technology is particularly suitable for high-density computing environments such as high-performance computing and large-scale data centers, and can significantly reduce energy consumption and operating costs.

[0003] At present, when placing IT equipment such as servers in immersion liquid cooling cabinets, in order to ensure orderliness, most of them are installed in a modular and equidistant arrangement on the mounting base (mounting frame) inside the cabinet. The modules are immersed in the coolant. When performing maintenance and repairs, the modular equipment needs to be taken out of the coolant. This process is relatively complicated. For example, when replacing or repairing faulty equipment, most of the time, it is necessary to drain some of the coolant first, disassemble the entire liquid cooling cabinet, and then manually and carefully remove the modular equipment from the liquid cooling cabinet. After the repair is completed, the coolant is re-injected and the system is debugged. The whole process is time-consuming and requires high technical personnel.

After the independent supporting part 52 supports the module mounting frame 3, the integral lifting part 51 can be used to lift the module mounting frame 3 below the coolant level to move the electronic information equipment to be repaired up. When the independent supporting part 52 releases the state of supporting the module mounting frame 3, the integral lifting part 51 is used not to lift the unsupported module mounting frame 3, so that a single, two or more modules can be selectively lifted according to the needs of repairing the module. A module mounting frame 3 is provided, and a supporting member 9 is arranged on each independent supporting part 52. The supporting member 9 is used to support the bracket 4 so that the overall lifting part 51 can synchronously lift the corresponding module mounting frame 3 and bracket 4. The lifting assembly 5 is arranged on the bracket 4, and the deflection assembly 7 is used to deflect the module mounting frame 3 lifted by the overall lifting part 51. When it is necessary to deflect the module mounting frame 3 to be repaired, the supporting member 9 is used to support the bracket 4 so that the module mounting frame 3 and the bracket 4 can be lifted together. When it is lifted above the coolant level, the deflection assembly 7 can be used to realize the deflection of the module mounting frame 3, which is convenient for maintenance operations.

[0020] Among them, in the specific implementation mode, refer to Figure 1-Figure 2 as well as Figure 5As shown, the integral lifting part 51 includes two servo motors 511 and two lead screws 514. The two servo motors 511 are symmetrically mounted on the upper ends of both sides of the cabinet body 1, and the output end of the servo motor 511 is mounted with a driving bevel gear 512 through a connecting shaft. A sealing ring can be arranged at the place where the connecting shaft passes through the cabinet body 1 to improve the sealing performance under the premise of ensuring rotation.

The driven bevel gear 513 drives the screw 514, so that the screw nut seat 516 can be lifted and lowered, and then the connecting strip 517 and the side plate 515 can be driven to lift and lower synchronously, thereby realizing the lifting of the module to be repaired.

[0021] See also Figure 5-Figure 6 As shown, the independent supporting part 52 includes a plurality of second electric telescopic rods 523 and second mounting grooves 524, and the plurality of second mounting grooves 524 are equidistantly arranged on a surface of the side plate 515 facing the bracket 4, one end of each bracket 4 corresponds to a second mounting groove 524, and a second electric telescopic rod 523 is installed at the bottom of each second mounting groove 524, and a first electric telescopic rod 521 perpendicular to the top of the second electric telescopic rod 523 is installed, and a support block 522 is fixed to the output end of the first electric telescopic rod 521, and a groove 44 for accommodating the support block 522 is opened in the middle of both ends of the bracket 4.

[0022] As described above, by starting the first electric telescopic rod 521, the first electric telescopic rod 521 can be used to drive the support block 522 to extend outward, so that the support block 522 can be located in the groove 44 (at the bottom end of the module mounting frame 3), and then the overall lifting part 51 is started to lift the supported module mounting frame 3. Secondly, the lifting and lowering of the first electric telescopic rod 521 can be adjusted by using the second electric telescopic rod 523. After two or more module mounting frames 3 are lifted above the liquid level at the same time, the height of each module mounting frame 3 can be further adjusted by the second electric telescopic rod 523 to achieve different height differences, reduce mutual obstruction, and further facilitate maintenance operations.

[0023] A gap is provided between the side plate 515 and the bracket 4, and the width of the gap is not less than the width of the support block 522, so that when the first electric telescopic rod 521 is retracted, the support block 522 can be completely separated from the bottom end of the module mounting frame 3 to release the supporting effect on the module mounting frame 3.

[0024] See also Figure 10-11 As shown, the supporting member 9 includes a third mounting groove 93 provided on the bracket block 522, a bidirectional electric telescopic rod 91 is installed in the middle of the third mounting groove 93, both ends of the bidirectional electric telescopic rod 91 are fixed with embedded blocks 92, and both sides of the inner side of the groove 44 are provided with embedded grooves 41 for accommodating the embedded blocks 92. When it is necessary to move up together with the bracket 4, the bidirectional electric telescopic rod 91 inside the groove 44 can be started at this time, and the bidirectional electric telescopic rod 91 can be used to drive the embedded block 92 to extend outward, so that the embedded block 92 is embedded in the embedded groove 41, and the embedded block 92 can be used to support the bracket 4, and the bracket 4 can be supported by the bracket 522 to support the module mounting frame 3, so that the module mounting frame 3 and the bracket 4 can be lifted synchronously.

[0025] Among them, an embedding bevel is provided at the outer end of the embedding block 92, the length of the embedding groove 41 is greater than the length of the embedding block 92, and the width of the embedding groove 41 is greater than the width of the embedding block 92. The setting of the embedding bevel and the length and width of the embedding groove 41 makes it easy for the embedding groove 41 to be embedded into the embedding groove 41.

[0026] See also Figure 7 -and Fig. 9 As shown, the deflection assembly 7 includes a rack 71 and a gear 72, one end of the rack 71 is connected to the side of the bracket 522 away from the first electric telescopic rod 521, the bottom end of the gear 72 is connected to the first connecting rod 73, the bottom end of the first connecting rod 73 is provided with a bearing seat embedded on the bracket 4, the top of the gear 72 is connected to the second connecting rod 74, the upper end of the outer wall of the second connecting rod 74 is fixed with a positioning protrusion 75, and the middle of the bottom end of the module mounting frame 3 is provided with a receiving groove for accommodating the second connecting rod 74 and the positioning protrusion 75, the rack 71 can be meshed with the gear 72, in the initial state, the rack 71 is not meshed with the gear 72, and meshes with the rack 71 as the rack 71 is pushed forward, and secondly, a first mounting is provided in the middle of the upper end surface of the bracket 4 Slot 42, gear 72 is arranged in the first mounting slot 42, and a movable slot 43 is further provided on the upper end surface of the bracket 4, the movable slot 43 is connected with the first mounting slot 42, and the rack 71 is in the movable slot 43. When the module mounting frame 3 of the coolant level needs to be deflected and transferred out (it is necessary to ensure that the module mounting frame 3 and the bracket 4 are lifted synchronously), at this time, the first electric telescopic rod 521 can be further extended, and the first electric telescopic rod 521 pushes the bracket 522 to move outward, thereby driving the rack 71 to move outward and engage with the gear 72. As it continues to move outward, the engaged gear 72 can be driven to rotate, thereby driving the second connecting rod 74 and the module mounting frame 3 at the top of the positioning protrusion 75 to deflect, and then the direction can be deflected according to the maintenance needs, which is more convenient and practical.

[0027] In order to ensure that the rack 71 moves smoothly along the moving groove 43 , it is necessary to ensure that the embedding groove 41 and the groove 44 have sufficient length to maintain sufficient moving space.

[0028] In addition, when returning the deflected module mounting frame 3 to its original position, the first electric telescopic rod 521 can be retracted, and when the rack 71 is out of meshing with the gear 72 , it returns to its original position.

[0029] Example 2: Please refer to Figure 1 and Figure 6 As shown, this embodiment is extended on the basis of the first embodiment. Specifically, a guide groove 8 is provided on the connecting strip 517, and a guide rod 6 is provided near the corner inside the cabinet body 1. The guide rod 6 passes through the guide groove 8, and the outer wall of the guide rod 6 is smooth without protrusions.

[0030] Through the above, when the integral lifting part 51 drives the module mounting frame 3 to rise and fall, the connecting strip 517 with the guide groove 8 moves along the guide rod 6, which can ensure the stability of the module mounting frame 3 in the lifting and falling, and is not prone to skewing.
