[0028] In order to more clearly illustrate the embodiments of the present invention, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0029] Example 1:

[0030] like Figure 1-3 As shown, the liquid cooling cabinet of this embodiment includes a cabinet body 1 and a lifting mechanism 2 installed in the cabinet body 1. The lifting mechanism 2 is used to lift the server 0 to facilitate maintenance operations on the server.

[0031] The above-mentioned lifting mechanism 2 includes a tray 3, a drive motor 4, a drive handle 5 and two pairs of transmission components 6. The tray 3 is located in the cabinet body 1 of the liquid cooling cabinet. The two pairs of transmission components 6 are respectively arranged on the opposite inner walls of the cabinet body 1 of the liquid cooling cabinet. The drive motor 4 and the drive handle 5 are used to drive the two pairs of transmission components 6 to synchronously drive the tray 3 up or down, thereby realizing the lifting or resetting of the server.

[0032] The transmission assembly 6 of this embodiment includes four transmission wheels 61 and a transmission belt 62. The transmission belt 62 crosses and wraps around the four transmission wheels to form two vertical transmission sections 620 that transmit in the same direction. Each vertical transmission section 620 is fixedly connected to a slider 7. The inner side wall of the cabinet body of the liquid cooling cabinet has a slide rail 8 corresponding to the slider 7 one by one. The slider 7 vertically slides and fits in its corresponding slide rail 8; wherein the slider 7 is fixedly connected to the tray 3, thereby realizing the transmission belt driving the tray to rise or fall.

[0033] The transmission belt 62 crosses and winds around the four transmission wheels 61 to form two triangular structures. The two triangular structures are centrally symmetrical with the vertices of the triangles, similar to a horizontal "8"-shaped structure.

[0034] like Figure 4As shown, the transmission assembly 6 of this embodiment also includes a meshing worm 91 and a worm wheel 92, wherein a pair of worms of the transmission assembly are drive-connected to the drive motor 4, and another pair of worms of the transmission assembly are drive-connected to the drive handle 5, which can realize both electric drive and manual drive, avoid the adverse effects of power outage or motor failure, and realize a redundant design of the drive; wherein, the worm wheel 91 is drive-connected to its adjacent target transmission wheel.

One of the transmission grooves of the pulley and the target transmission wheel is driven by a belt, and the other transmission groove is mounted with a transmission belt 62 .

[0037] The tray 3 of this embodiment is used to place the server. Figure 5 As shown, the tray 3 has an array of through holes 30 so that the coolant can cool the bottom of the server; in addition, both sides of the tray 3 have vertically extending convex edges 31, which are fixedly connected to the slider 7.

[0038] The above-mentioned fixed connection and transmission connection are both commonly used connection methods and will not be described in detail here.

[0039] The liquid cooling cabinet of this embodiment adopts the lifting mechanism of this embodiment to realize convenient lifting of the server, and has a simple structure, avoiding the stroke and thrust balance problems faced by using multiple electric and hydraulic push rods.

[0040] Example 2:

[0041] The lifting mechanism of this embodiment is different from that of embodiment 1 in that:

[0042] The worm, worm wheel and their auxiliary structures are omitted, and the transmission wheel is directly driven by the drive motor, which simplifies the overall structure and meets the needs of different applications;

[0043] For other structures, please refer to Example 1;
