In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Referring to FIG. 1 , a liquid-cooled server provided by an embodiment of the present invention includes a casing 10 , and the casing 10 is applied in the field of immersion liquid cooling.

In one embodiment, referring to FIG. 2 and FIG. 3 , the housing 10 includes a first housing 11 and a second housing 12. The first housing 11 is provided with a first receiving cavity 111, and the first receiving cavity 111 is used to receive the computing module. The second housing 12 is provided at one side of the first housing 11 and is fixedly connected to the first housing 11, and the second housing 12 is provided with a second receiving cavity 121, and the second receiving cavity 121 is used to receive the IO module 20.

Specifically, the computing module includes a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc. When working, the computing module generates a large amount of heat due to the computing, so a cooling liquid is provided in the first receiving chamber 111, and the cooling liquid is used to immerse the computing module to cool the computing module and dissipate heat. Therefore, the first housing 11 can also be understood as a wet area.

Specifically, the IO module 20 includes an IO function board 21. A transfer hole is provided on the side of the second housing 12 facing away from the first housing 11, and an optical fiber adapter is provided in the transfer hole, and the optical fiber adapter is connected to the IO function board 21. When working, the IO module 20 does not participate in the calculation and generates less heat, so there is no need to use cooling liquid, so the second housing 12 can also be understood as a dry area. The use of a dry and wet separation structure can effectively reduce the amount of cooling liquid.

In order to facilitate the connection between the computing module and the IO module 20, a through hole 112 is provided on one side where the first housing 11 and the second housing 12 are connected, and the through hole 112 is connected to the first receiving cavity 111 and the second receiving cavity 121. During installation, the transmission cable is provided in the through hole 112, one end of the transmission cable is located in the first receiving cavity 111 and connected to the computing module, and the other end of the transmission cable is located in the second receiving cavity 121 and connected to the IO module 20 to achieve data transmission.

It should be noted that the number of transmission cables can also be set according to actual needs, and no specific limitation is made here. In this embodiment, there are six transmission cables, namely USB/BTN (Universal Serial Bus/Power Button) cable, VGA (Video Graphics Array) cable, NIC (network interface card) cable, PWR/I2C cable and two 100G optical fiber cables. Among them, the optical fiber cable is connected to the optical fiber adapter.

In one embodiment, referring to FIG. 3 , the housing 10 further includes a liquid leakage prevention assembly 13. The liquid leakage prevention assembly 13 is disposed at the through hole 112, and the liquid leakage prevention assembly 13 is used to compress the transmission cable to seal and isolate the first receiving chamber 111 from the second receiving chamber 121. By disposing the liquid leakage prevention assembly 13 at the through hole 112, the liquid leakage prevention assembly 13 can compress the transmission cable to seal and isolate the first receiving chamber 111 from the second receiving chamber 121, thereby preventing the cooling liquid in the first receiving chamber 111 from entering the second receiving chamber 121 through the through hole 112 and affecting the function of the IO module, thereby improving the service life of the liquid-cooled server.

In one embodiment, referring to FIG. 3 , FIG. 4 and FIG. 5 , the anti-leakage assembly 13 includes a gland 131. The gland 131 has a first connection end 1311, which is disposed in the through hole 112 and connected to the hole wall of the through hole 112. The gland 131 is provided with a first through hole 1313 for the transmission cable to pass through. During installation, the transmission cable is disposed in the first through hole 1313, one end of the transmission cable is located in the first receiving cavity 111 and connected to the computing module, and the other end of the transmission cable is located in the second receiving cavity 121 and connected to the IO module 20. By providing the Gland head 131, the Gland head 131 can also seal the transmission cable to prevent the cooling liquid in the first receiving chamber 111 from entering the second receiving chamber 121 through the through hole 112 and affecting the function of the IO module. In addition, the Gland head 131 can lock the transmission cable to prevent the axial displacement and radial rotation of the transmission cable, and ensure that the two ends of the transmission cable are normally connected to the computing module and the IO module 20 respectively.

Optionally, the hole wall of the through hole 112 is provided with threads. The outer peripheral surface of the first connecting end 1311 is provided with threaded sections, and the first connecting end 1311 is arranged in the through hole 112 and is threadedly connected to the hole wall of the through hole 112. The gland 131 is installed on the first housing 11 by means of threaded connection, which facilitates the disassembly of the gland 131, and further facilitates the disassembly of the transmission cable.

In one embodiment, referring to FIG. 3 , FIG. 4 and FIG. 5 , the anti-leakage assembly 13 further includes a sealing member 132. The sealing member 132 is disposed in the first through hole 1313, and the outer peripheral surface of the sealing member 132 is sealed with the hole wall of the first through hole 1313. The sealing member 132 is provided with a second through hole 1321 for the transmission cable to pass through. Thus, by disposing the sealing member 132 in the first through hole 1313, the sealing member 132 further seals the transmission cable, effectively sealing and isolating the first receiving chamber 111 and the second receiving chamber 121, and effectively preventing the cooling liquid in the first receiving chamber 111 from entering the second receiving chamber 121 through the through hole 112 and affecting the function of the IO module.

Optionally, the sealing member 132 is a rubber sealing ring, and the outer peripheral surface of the rubber sealing ring is pressed against the hole wall of the first through hole 1313. Of course, in other embodiments, the sealing member 132 can also be made of other materials.

Furthermore, the number of the second through holes 1321 is equal to the number of the transmission cables, and the diameter of each second through hole 1321 is equal to the outer diameter of the transmission cable to be installed. During installation, the transmission cables are placed in the second through holes 1321 one by one, and the hole walls of the second through holes 1321 wrap around the outer peripheral surface of the transmission cables to avoid gaps between two adjacent transmission cables and leakage, thereby improving the sealing effect.

In this embodiment, referring to FIG. 5 , there are six second through holes 1321 , and the six second through holes 1321 are arranged at intervals along the circumference of the sealing member 132 . The six transmission cables are arranged in the six second through holes 1321 , respectively.

A plurality of first elastic arms 1314 are provided on one side of the second connection end 1312 away from the first connection end 1311, and all the first elastic arms 1314 are arranged at intervals along the circumference of the gland 131, and the seal 132 is arranged in the space surrounded by the first elastic arms 1314. Furthermore, the anti-leakage assembly 13 further includes a nut 133, which is sleeved on the first elastic arm 1314 and the second connection end 1312, and the nut 133 is threadedly connected to the second connection end 1312. During installation, an external force acts on the nut 133, causing the nut 133 to rotate. During the rotation, the nut 133 squeezes the first elastic arm 1314, causing the seal 132 to be tightly deformed to compress the transmission cable, thereby achieving a sealing effect.

In one embodiment, referring to Figures 1 and 6, a power-assisting handle 14 is provided on a side of the second housing 12 away from the first housing 11. During installation, the housing 10 is arranged corresponding to the opening of the cabinet, and an external force acts on the power-assisting handle 14, so that the housing 10 can be quickly pushed into the cabinet.

It should be noted that the number of the power-assisting handles 14 can be set according to actual needs and is not specifically limited here. In this embodiment, referring to FIG. 6 , there are two power-assisting handles 14 , one of which is disposed on the upper portion of the second housing 12 and the other is disposed on the lower portion of the second housing 12 .

In one embodiment, referring to FIG. 6 , the power-assisting handle 14 has a first end 141 and a second end 142 , and the first end 141 and the second end 142 are respectively two ends of the power-assisting handle 14 along its length direction.

Further, referring to FIG. 6 and FIG. 7 , the first end 141 is rotatably mounted on the second housing 12, and the first end 141 is provided with a slot 1411 for clamping the cabinet. The notch of the slot 1411 is arranged away from the second end 142. Optionally, the first end 141 is rotatably mounted on the upper part and/or the lower part of the second housing 12. When the first end 141 is rotatably arranged on the upper part of the second housing 12, the slot 1411 is arranged upward so that the slot 1411 clamps the preset position of the top of the cabinet. When the second end 142 is rotatably arranged on the lower part of the second housing 12, the slot 1411 is arranged downward so that the slot 1411 clamps the preset position of the bottom of the cabinet.

Further, referring to Figures 6 and 7, the second end 142 is detachably mounted on the second housing 12. Optionally, the second end 142 is provided with a first mounting hole 1421, and a second mounting hole is correspondingly provided on a side of the second housing 12 away from the first housing 11, and mounting members 17 are provided in the first mounting hole 1421 and the second mounting hole. The mounting member 17 is a screw.

The mounting member 17 is removed to separate the second end 142 from the second housing 12. Then, the power-assisting handle 14 is rotated to rotate the second end 142 away from the second housing 12, and the clamping groove 1411 of the first end 141 is clamped in the preset position of the cabinet. At this time, the power-assisting handle 14 is equivalent to a lever arm. Then, the power-assisting handle 14 is rotated in the opposite direction to rotate the second end 142 toward the second housing 12. In the process of the second end 142 rotating toward the second housing 12, the housing 10 is gradually pushed into the cabinet. When the housing 10 is completely pushed into the cabinet, the second end 142 is fixed to the second housing 12 using the mounting member 17. In this way, the housing 10 is pushed into the cabinet by the lever principle, which can achieve the purpose of labor saving. Only one person can perform operation and maintenance, saving manpower.

7 and 9, the slot walls of the slot 1411 at both ends along the width direction of the power handle 14 are provided with first avoidance openings 1412. During installation, the first avoidance openings 1412 can avoid the preset position of the cabinet, making it easier for the slot 1411 to lock the preset position of the cabinet, and avoiding the failure to lock the preset position of the cabinet due to interference from the slot walls.

In one embodiment, referring to FIG. 7 and FIG. 8 , the second housing 12 is provided with a receiving groove 122. The groove wall of the receiving groove 122 includes a first groove wall 1221 and a second groove wall 1222 opposite to each other, and the first groove wall 1221 is provided away from the first housing 11 relative to the second groove wall 1222. The first groove wall 1221 is provided with a second avoidance opening 1223. The first end 141 is provided in the receiving groove 122 through the second avoidance opening 1223. By providing the second avoidance opening 1223, the second avoidance opening 1223 avoids the first end 141 of the power-assisting handle 14, so that the first end 141 of the power-assisting handle 14 is provided in the receiving groove 122 through the second avoidance opening 1223.

Further, referring to FIG. 7 and FIG. 8 , a connecting shaft 15 is provided in the receiving groove 122. Both ends of the connecting shaft 15 are respectively connected to the two groove walls between the first groove wall 1221 and the second groove wall 1222. Specifically, the first end 141 is provided with a first shaft hole 1413, and both groove walls between the first groove wall 1221 and the second groove wall 1222 are provided with a second shaft hole 124, and both ends of the connecting shaft 15 are respectively provided in the first shaft hole 1413 and the second shaft hole 124. An elastic member 16 is provided on the connecting shaft 15, and a second elastic arm 161 is provided at one end of the elastic member 16, and a third elastic arm 162 is provided at the other end of the elastic member 16. The second elastic arm 161 abuts against the second housing 12, and the third elastic arm 162 abuts against the power-assisting handle 14. After the second end 142 of the power-assisting handle 14 is disassembled and separated from the second housing 12, the second end 142 of the power-assisting handle 14 rotates away from the second housing 12 under the action of the elastic member 16, so that the power-assisting handle 14 is kept at the maximum opening and closing angle, so as to push the housing 10 into the cabinet.

Optionally, the connecting shaft 15 is a pin. Of course, in other embodiments, the connecting shaft 15 can also be other components, not limited to this.

In one embodiment, referring to FIG. 8 , the bottom of the receiving groove 122 is horizontally arranged. The second groove wall 1222 is inclined relative to the groove bottom, and the second groove wall 1222 is inclined from the groove bottom to the groove opening toward the direction close to the first housing 11. During installation, the power-assisting handle 14 is rotated so that the first end 141 rotates toward the direction close to the second groove wall 1222. Since the second groove wall 1222 is inclined from the groove bottom to the groove opening toward the direction close to the first housing 11, the inclined second groove wall 1222 provides an avoidance position for the rotation of the power-assisting handle 14. When the power-assisting handle 14 rotates until the first end 141 is in contact with the second groove wall 1222, the slot 1411 of the first end 141 is tilted forward relative to the pushing direction, so that the slot 1411 can be clamped at the preset position of the top and/or bottom of the cabinet before the housing 10 is pushed into the cabinet. In addition, the second groove wall 1222 can also play a limiting role to prevent the power-assisting handle 14 from rotating excessively. In addition, when the slot 1411 is clamped at the preset position of the cabinet, the first end 141 can be pressed against the second groove wall 1222, so that the slot 1411 of the first end 141 can quickly clamp at the preset position of the cabinet.

In one embodiment, the first housing 11 and the second housing 12 are detachably connected, so that it is convenient to inspect and maintain the IO module 20 and the like in the liquid-cooled server.

In one embodiment, the top and bottom of the first housing 11 are provided with a first connection hole. The top and bottom of the second housing 12 are provided with connection ears 123, respectively, and the connection ears 123 are provided with a second connection hole.
