[0028] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model will be further described in detail in combination with the drawings and examples.

[0029] Example 1

[0030] As shown in the figure, a sliding immersion type server case with adjustable liquid amount is provided. Figure 1 The whole case is divided into an upper case and a lower case for the convenience of liquid cooling deployment. The upper case is used for arranging servers, and the lower case is used for cooling the cooling liquid. Secondly, the structure of the lower case is similar to a sliding rail mechanical structure, which is convenient for maintenance work after the cooling liquid is discharged. Then, two groups of refrigeration layers are symmetrically installed at the front and back of the lower case, which are used for refrigerating the cooling liquid and guaranteeing stable refrigeration effect. Finally, a mechanical mechanism with compressible space is designed in the lower case to compress or release the space to adjust the height of the cooling liquid. When the space is completely compressed, the whole cooling liquid surface is the highest. When the space is completely released, the whole cooling liquid is completely recovered to the lower case.

[0031] In the structural design, the server case comprises an upper case chamber 1, a lower case chamber 2, and a partition plate 3 installed and connected between the upper case chamber 1 and the lower case chamber 2, which are separated by the partition plate 3; the partition plate 3 is provided with a passage opening for the cooling liquid to pass through, and the passage opening is provided with a two-way hydraulic valve 4 for controlling the passage of the cooling liquid; at the same time, the lower case chamber 2 is provided with a piston 5, one end of the piston 5 close to the partition plate 3 is provided in sliding contact with the partition plate 3, and the other end of the piston 5 away from the partition plate 3 is provided in sliding contact with the inner wall of the lower case chamber 2, one end of the piston 5 is connected with a piston rod 6, and the other end of the piston rod 6 away from the piston 5 is movably arranged through the side wall of the lower case chamber 2 and the end thereof is connected with the output end of a cylinder.

[0032] In the embodiment, the cooling liquid for cooling is introduced into the lower case chamber 2 of the server case which is specially used for containing the cooling liquid; when the cooling liquid needs to be used, the piston 5 is controlled to move, the piston 5 extrudes the cooling liquid in the lower case chamber 2, at this time the two-way hydraulic valve 4 is opened, the cooling liquid enters the upper case chamber 1 through the passage opening of the partition plate 3, and then the cooling liquid is controlled by the upper case chamber 1 to perform "circulating heat dissipation" on the server case. When the amount (which can be understood as the height) of the cooling liquid in the upper case chamber 1 needs to be controlled according to the actual situation, at this time an active adjusting mechanism is arranged between the piston 5 and the inner wall of the lower case chamber 2, and the active adjusting mechanism is used to adjust the amount of the cooling liquid in the upper case chamber 1.

[0033] Embodiment 2

[0034] Further, based on embodiment 1, the active adjusting mechanism comprises an active adjusting block 7; the active adjusting block 7 is arranged between the piston 5 and the bottom end of the inner wall of the lower case chamber 2, one end of the active adjusting block 7 close to the piston 5 is provided with a sliding groove, one end of the piston 5 close to the active adjusting block 7 is connected with a sliding block, the sliding block and the sliding groove are arranged in sliding fit, and the bottom end of the active adjusting block is connected with the bottom end of the inner wall of the lower case chamber 2. At the same time, the active adjusting block 7 is provided with an active blind hole, and an active blind hole plug is arranged in the active blind hole; one end of the active blind hole plug is connected with a connecting rod 71, the other end of the connecting rod 71 is movably arranged through the side wall of the lower case chamber 2, and the end thereof is connected with the delivery end rod body of a hydraulic rod 72, and the hydraulic rod 72 is fixedly installed on the outer side wall of the lower case chamber 2.

[0035] In the embodiment, the hydraulic rod 72 drives the connecting rod 71 to move, so as to drive the active blind hole plug to move in the active blind hole according to the "driving depth" of the active blind hole plug, and the amount of the cooling liquid entering is controlled. Since the upper case chamber 1 and the lower case chamber 2 are connected, the amount of the cooling liquid in the upper case chamber 1 can be accurately controlled and adjusted, so as to meet the use requirements.

[0036] It should be noted that, due to the large overall piston 5, in the entire embodiment, to achieve the adjustment of the overall amount of coolant in the upper machine box chamber 1, the lower machine box chamber 2; if you need to adjust the actual use of the amount of coolant in the upper machine box chamber 1, you need to achieve through the "active adjustment mechanism".

[0037] Further, the outer wall of the set of movable blind hole plug is connected with a limiting block on both sides, and the inner wall of the movable blind hole is provided with a limiting sliding groove on both sides which is slidingly matched with the limiting block. In this embodiment, when controlling the movement of the movable blind hole plug in the movable blind hole, the limiting block and the limiting sliding groove are slidingly matched, which can not only stabilize the guidance, but also ensure that the movable blind hole plug is in close contact with the inner wall of the movable blind hole, thereby ensuring its air tightness. In addition, the movable adjusting block 7 is movably connected with the piston 5 and is arranged between the piston 5 and the inner wall bottom end of the lower machine box chamber 2. When the piston 5 is stationary, the movable adjusting block 7 is also stationary. Therefore, by controlling the movement of the movable blind hole plug in the movable blind hole, the coolant can only enter the movable blind hole under the action of pressure, and the amount of coolant entering or flowing out of the movable blind hole is the amount of "decrease" or "increase" adjustment of the upper machine box chamber 1 at this time. The amount of coolant in the upper machine box chamber 1 is adjusted by the movable adjusting mechanism, and the "accurate adjustment" is made according to the actual needs.

[0038] In order to "accurately adjust" the amount of coolant in the upper machine box chamber 1 according to the actual needs, it is fully utilized. Therefore, a length sensor is installed and connected on one side of the outer wall of the lower machine box chamber 2 close to the output end of the hydraulic rod 72. The length sensor is electrically connected with the control module. The length of the output end of the hydraulic rod 72 "in and out" of the lower machine box chamber 2 is measured by the length sensor. Through design and calculation, the length of the output end of the hydraulic rod 72 "in and out" is converted into the volume of coolant entering the "movable blind hole", so as to realize the "accurate" control and adjustment of the amount of coolant in the upper machine box chamber 1.

[0039] For example:

[0040] Through the length sensor counting, the output end rod body of the hydraulic rod 72 of 1 unit length is converted into the volume of the movable blind hole V1, and 1 unit of V1 is converted into the volume of the upper machine box chamber 1 V2; therefore, finally, 1 unit length of the hydraulic rod 72, the movable blind hole plug realizes the volume of the movable blind hole V1, and the volume change amount of the cooling liquid in the upper machine box chamber 1 is 1 unit of the volume of the upper machine box chamber 1, that is, V2; then, through the volume formula of the volume of the upper machine box chamber 1, it is converted into the height of the cooling liquid in the upper machine box chamber 1, and finally the amount of the cooling liquid is controlled through the height change, so as to achieve the design purpose. In the calculation process, the calculation formula (volume formula) is the prior art, and the proportional relationship is determined according to the size relationship between the two during design. These are prior art, and in this example, they are not specifically described.

[0041] Embodiment 3

[0042] Further, the piston 5 is connected with a top movable block at one end close to the partition plate 3, the top movable block is arranged in sliding contact with the partition plate 3; the partition plate 3 is connected with a stop plate 8 at one end surface close to the piston 5, the stop plate 8 is arranged on the same axis line with the top movable block. A stop limiting movable rod is movably arranged on the stop plate 8, one end of the stop limiting movable rod close to the top movable block is arranged in elastic contact with the top movable block. A shape change spring is movably arranged on the stop limiting movable rod, one end of the shape change spring is connected with the stop plate 8, and the other end of the shape change spring is connected with the stop limiting movable rod. An alarm sensor is installed on the stop plate, the alarm sensor is electrically connected with the control module, and the control module is further electrically connected with an alarm. A sealing rubber ring is sleeved on the outer wall of the piston, and the piston is arranged in close contact with the inner wall of the partition plate and the lower machine box chamber through the sealing rubber ring.

[0043] In the embodiment, when the cooling liquid in the lower machine box chamber 2 is “introduced” into the upper machine box chamber 1 through the piston 5, due to the design, the volume of the lower machine box chamber 2 is greater than that of the upper machine box chamber 1, so the cooling liquid contained in the lower machine box chamber 2 is greater than that in the upper machine box chamber 1, which can facilitate the adjustment of the amount of the cooling liquid in the upper machine box chamber 1 and the subsequent maintenance. Therefore, when the piston 5 moves to the position of the stop plate 8 and elastically abuts against the stop limiting movable rod, the alarm sensor receives the signal feedback to the alarm sensor at this time, reminding that the cooling liquid in the upper machine box chamber 1 reaches the maximum limit. When the piston 5 is controlled to move “in the opposite direction”, all the cooling liquid in the upper machine box chamber 1 can be “sucked” into the lower machine box chamber 2, which facilitates the cleaning and maintenance of the upper machine box chamber 1. When the lower machine box chamber 2 needs to be cleaned and maintained, the entire piston 5 and the connecting structure of the piston 5 are removed, and the piston 5, the connecting structure of the piston 5 and even the lower machine box chamber 2 are cleaned and maintained.

[0044] In addition, temperature sensors are installed in the lower cabinet chamber 2 and the upper cabinet chamber 1, respectively, and are electrically connected to the control module. When the temperature in the lower cabinet chamber 2 or the upper cabinet chamber 1 exceeds a set threshold value, the control module can control the piston 5 to reciprocate, so that the coolant in the lower cabinet chamber 2 or the upper cabinet chamber 1 is subjected to “overall cold-hot mixing and exchange”, thereby improving the utilization efficiency of the coolant.
