Description

Technical Field

[0001] The invention belongs to the technical field of servers, and in particular relates to a liquid-cooling server. Background Art

[0002] The server is composed of multiple motherboards. When the motherboard performs high-speed calculations and processes data, a large amount of heat will be generated. If this heat cannot be removed in a timely and effective manner, the motherboard temperature will continue to rise, which will in turn affect the normal operation and overall performance of each electronic component on the motherboard. In order to ensure the stable operation of the server and extend its service life, effective cooling measures must be taken to dissipate the heat of the motherboard to prevent overheating from adversely affecting server performance.

DETAILED DESCRIPTION

[0030] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] Example: Reference Figure 1-Figure 14 A liquid-cooled server comprises a bottom 1, a frame 2 is arranged on the bottom 1, three groups of liquid cooling units are arranged on the bottom 1, the liquid cooling unit comprises a socket 3, a mainboard 4 is inserted into the socket 3, heat sinks 5 are arranged on both sides of the mainboard 4, the heat sinks 5 are used to cool the mainboard 4, the heat sinks 5 are slidably arranged on a vertical slide seat 6, the vertical slide seat 6 is fixedly arranged on the bottom 1, two ends of a spring 7 are respectively connected to the heat sink 5 and the vertical slide seat 6, L-shaped plates 8 are arranged on both sides of the heat sink 5, two ends of a side connecting rod 9 are respectively hinged to the end of the L-shaped plate 8 and a rotating plate 10, a turning handle 11 is arranged in the middle of the rotating plate 10, and the turning handle 11 is rotatably arranged on the frame 2.

[0032] Specifically, the turning handle 11 is rotated to drive the rotating plate 10 to rotate, and the power is transmitted through the side connecting rod 9, so that the heat sink 5 moves on the vertical sliding seat 6 in the direction away from the main board 4, and the spring 7 is compressed.

[0033] The socket 3 is provided with long vertical plates 12 on both sides, and the long vertical plates 12 are fixed on the bottom 1. A slide 13 is slidably provided on the top of the long vertical plates 12. Guide rods 14 are slidably provided at both ends of the slide 13. A bump block 15 is provided at the end of the guide rod 14. The two ends of the spring 16 are respectively connected to the slide 13 and the bump block 15. A pressing shaft 17 is provided between the two bump blocks 15 of the heat sink 5 on each side. The two ends of the pressing connecting rod 18 are respectively hinged to the pressing shaft 17 and the pressing seat 19. The pressing seat 19 is fixed on the heat sink 5 on this side. A pressing cylinder 20 is rotatably provided on the pressing shaft 17. The pressing cylinder 20 is used to press the mainboard 4 into the socket 3.

[0034] Specifically, when the two heat sinks 5 are in the open state, the slide 13 contacts the boss at the upper end of the long vertical plate 12. When the two heat sinks 5 move toward the direction of the main board 4, the heat sink 5 is close to the surface of the main board 4, and the heat sink 5 dissipates heat for the main board 4. The heat sink 5 drives the pressure seat 19 to move synchronously. During the movement of the pressure seat 19, the spring 2 16 provides elastic force to make the guide rod 14, the bump block 15, the pressure shaft 17, and the pressure connecting rod 18 move synchronously. After the two bump blocks 15 touch, the two bump blocks 15 no longer move, while the heat sink 5 continues to move, and the pressure connecting rod 18 rotates on the pressure seat 19 to make the bump block 15 and the pressure shaft 17 move downward, and the slide 13 also moves downward along the long vertical plate 12. The pressure shaft 17 brings the pressure cylinder 20 down synchronously, and the pressure cylinder 20 presses the main board 4 into the socket 3.

[0035] When the two heat sinks 5 move away from the main board 4, the spring 2 16 provides elastic force, so that the bump block 15 and the guide rod 14 no longer move on the slide 13, so the slide 13 moves upward on the long vertical plate 12, and the bump block 15, the pressure shaft 17 and the pressure cylinder 20 move upward synchronously with the slide 13. When the slide 13 contacts the boss at the upper end of the long vertical plate 12, the slide 13 no longer moves upward, and the heat sink 5 moves outward with the pressure seat 19, the pressure connecting rod 18 and the bump block 15, so the two pressure cylinders 20 move outward to make room for placing the main board 4.

[0036] Two positioning plates 401 are disposed on both sides of the main board 4 .

[0037] The heat dissipation plate 5 is provided with a heat dissipation channel 501 inside, and the two ends of the heat dissipation channel 501 are respectively connected to the inlet and outlet of the heat dissipation channel 501, wherein the heat dissipation channel 501 is a reciprocating channel, and the coolant flows in the heat dissipation channel 501 to take away the heat.

[0038] The heat sink 5 is provided with a positioning assembly, which includes a transverse plate 21, which is slidably arranged on the plug-in slide seat 22, and the two ends of a spring three 23 are respectively connected to the transverse plate 21 and the plug-in slide seat 22, and the two ends of the transverse plate 21 are respectively slidably provided with positioning slide rods 24, and the ends of the positioning slide rods 24 are provided with positive positioning blocks 25, and the two ends of a spring four 26 are respectively connected to the transverse plate 21 and the positive positioning block 25, and the upper and lower sides of the positive positioning block 25 are provided with oblique slide grooves 27, and the four corners of the side positioning block 28 are provided with oblique slide blocks 281, and the oblique slide blocks 281 on both sides of the side positioning block 28 respectively form a sliding fit with the oblique slide grooves 27 of the positioning assemblies of two adjacent main boards 4.

[0039] The surfaces of the front positioning block 25 and the side positioning block 28 are both provided with shock-absorbing pads, which position the positioning plate 401 of the main board 4 and prevent the main board 4 from being damaged.

[0040] Specifically, when the two heat sinks 5 move toward the direction of the main board 4, the insert slide 22 drives the cross plate 21 to move synchronously, and then transmits power through the spring four 26 to make the positioning slide bar 24 and the positive positioning block 25 move toward the direction of the positioning plate 401. When the two positive positioning blocks 25 move toward the direction of the positioning plate 401, the inclined slide block 281 of the side positioning block 28 slides on the inclined slide groove 27, that is, the side positioning block 28 moves toward the side of the positioning plate 401, so the two positive positioning blocks 25 and the side positioning blocks 28 position and clamp the positioning plate 401 of the main board 4, and the heat sink 5 continues to move toward the direction of the main board 4, the positive positioning blocks 25 and the side positioning blocks 28 no longer move, and the cross plate 21 slides on the positioning slide bar 24, and the spring four 26 is compressed.

[0041] After the two positive positioning blocks 25 and the side positioning blocks 28 position and clamp the positioning plate 401 of the main board 4, when the main board 4 moves downward, the main board 4 moves downward synchronously with the cross plate 21 and the cross plate 21 moves downward along the sliding seat 22, and the spring three 23 extends.

[0042] The liquid cooling unit also includes a connecting pipe 29, the middle part of which is fixed on a long vertical plate 12, and the two ends of the connecting pipe 29 are respectively slidably connected to the inlet and outlet of the two heat sinks 5 of the liquid cooling unit; the inlet and outlet of the heat sinks 5 close to each other of the two adjacent liquid cooling units are respectively slidably connected to the two ends of a connecting pipe 2 30, and the connecting pipe 2 30 is fixed on another long vertical plate 12; the inlet of a heat sink 5 of the first group of liquid cooling units is slidably connected to one end of a connecting pipe 3 31, and the other end of the connecting pipe 3 31 is connected to the inlet of a cooling liquid source 33; the outlet of a cooling plate 5 of the third group of liquid cooling units is slidably connected to one end of a connecting pipe 4 32, and the connecting pipe 4 32 is connected to the inlet of a cooling liquid source 33, and the cooling liquid source 33 is fixed on the bottom 1.

[0043] Specifically, the cooling liquid source 33 provides cooling liquid, and the cooling liquid enters the heat sink 5 of the first group of liquid cooling units through the connecting pipe four 32. The cooling liquid is transported between two heat sinks 5 in each group of liquid cooling units by a connecting pipe one 29, and the cooling liquid is transported between the heat sinks 5 of adjacent liquid cooling units by a connecting pipe two 30. The cooling liquid is transported between the heat sink 5 of the third group of liquid cooling units and the cooling liquid source 33 by a connecting pipe four 32.

[0044] The bottom 1 is provided with a partition 34 for isolating the cooling liquid source 33 from the liquid cooling unit. Air holes 201 are provided on both sides of the frame 2 , and the air holes 201 of the frame 2 are located on both sides of the cooling liquid source 33 .

[0045] Specifically, the heat of the cooling liquid source 33 is dissipated from the air holes 201 of the frame 2, and at the same time, the partition 34 seals the liquid cooling unit in a sealed environment to prevent dust from being spread on the liquid cooling unit, thereby avoiding performance damage.

[0046] The bottom 1 is provided with a rotating shaft 35, one end of a fixed link 36 is connected to the rotating shaft 35, the other end of the fixed link 36 is hinged to one end of a lower link 37, the other end of the lower link 37 is hinged to the middle of a clamping plate 38, the clamping plate 38 is provided with three lower drive plates 39, the lower drive plates 39 are provided with racks 40, the racks 40 are used to mesh with gears 41, the gears 41 are fixedly arranged on the rotating shaft of the corresponding turning handle 11, the lower drive plates 39 are slidably arranged on the lower sliding seat 42, the two ends of a spring 43 are respectively connected to the lower drive plates 39 and the lower sliding seat 42, and the lower sliding seat 42 is fixedly arranged on the inner side of the frame 2.

[0047] The rotating shaft 35 is provided with a handle 44 .

[0048] Specifically, twisting the handle 44 causes the shaft 35 to rotate, and power is transmitted through the fixed connecting rod 36 and the lower connecting rod 37 to drive the clamping plate 38 to move downward, and the clamping plate 38 drives the three lower drive plates 39 to move downward, the spring 43 is compressed, and the rack 40 begins to engage with the gear 41, and the rack 40 drives the gear 41 to rotate, thereby rotating the handles 11 of the three groups of liquid cooling units.

[0049] Working principle: when the mainboard 4 needs to be installed, open the upper cover of the frame 2, manually turn the handle 11 to drive the rotating plate 10 to rotate, transmit power through the side connecting rod 9, so that the heat sink 5 moves on the vertical slide 6 in the direction away from the mainboard 4, and the spring 7 is compressed to put the two heat sinks 5 in the open state. The slide 13 contacts the boss at the upper end of the long vertical plate 12, and the heat sink 5 moves outward with the pressure seat 19, the pressure connecting rod 18 and the bump block 15, and the two pressure cylinders 20 move outward synchronously to make room for placing the mainboard 4. The mainboard 4 is placed on the socket 3, and the positioning plate 401 of the mainboard 4 is located between each pair of positive positioning blocks 25. The turning handle 11 is released, and the spring 1 7 provides power to move the two heat sinks 5 toward the direction of the mainboard 4. The plug slide 22 drives the cross plate 21 to move synchronously, and then the power is transmitted through the spring 4 26 to move the positioning slide bar 24 and the positive positioning block 25 toward the direction of the positioning plate 401 of the mainboard 4. The positive positioning block 25 drives the inclined slide groove 27 to move synchronously, and the inclined slide block 281 of the side positioning block 28 slides on the inclined slide groove 27, that is, the side positioning block 28 moves to the side of the positioning plate 401 of the mainboard 4. Therefore, the two positive positioning blocks 25 and the side positioning blocks 28 automatically position and clamp the positioning plate 401 of the mainboard 4, that is, the mainboard 4 can be fixed. The plate 4 is positioned and clamped to ensure that the mainboard 4 can be aligned with the socket 3; the two heat sinks 5 continue to move in the direction of the mainboard 4, the positive positioning block 25 and the side positioning block 28 no longer move, the cross plate 21 slides on the positioning slide 24, the spring four 26 is compressed, and after the two bump blocks 15 touch, the two bump blocks 15 no longer move, the pressing connecting rod 18 rotates on the pressing seat 19, so that the bump blocks 15 and the pressing shaft 17 move downward, the slide 13 also moves downward along the long vertical plate 12, the pressing shaft 17 brings the pressing cylinder 20 down synchronously, and the pressing cylinder 20 automatically presses the mainboard 4 into the socket 3 to ensure that the mainboard 4 is automatically connected to the socket 3, the mainboard 4 moves downward synchronously with the cross plate 21 and the cross plate 21 moves downward along the plug sliding seat 22, and the spring three 23 stretches.

[0050] When the main board 4 needs to be repaired, the handle 11 is manually turned in the reverse process of the above principle. The two pressure cylinders 20 move outward, and the pressure cylinder 20 is separated from the main board 4 to make room for pulling out the main board 4. The spring three 23 contracts, and the spring three 23 provides power to move the cross plate 21 upward. The positive positioning block 25 and the side positioning block 28 still clamp the main board 4 and automatically pull the main board 4 out of the socket 3. The two heat sinks 5 continue to move away from the main board 4. In the reverse process of the above principle, the positive positioning block 25 and the side positioning block 28 release the main board 4, making it easy to take out the main board 4 for repair.

[0051] The heat sink 5 is in close contact with the surface of the mainboard 4, and the heat sink 5 dissipates heat for the mainboard 4. The coolant source 33 provides coolant, and the coolant is transported through the connecting pipe 1 29, the connecting pipe 2 30, the connecting pipe 3 31, and the connecting pipe 4 32, so that all the heat sinks 5 are filled with flowing coolant. The coolant brings the heat of the mainboard 4 to the coolant source 33, and the heat of the coolant source 33 is dissipated from the air holes 201 of the frame 2. At the same time, the partition 34 seals the liquid cooling unit in a sealed environment to prevent dust from being spread on the liquid cooling unit, thereby avoiding performance damage.

[0052] When it is necessary to install or overhaul all the mainboards 4 at the same time, twist the handle 44 to rotate the shaft 35, transmit power through the fixed connecting rod 36 and the lower connecting rod 37, drive the clamping plate 38 to move downward, the clamping plate 38 drives the three lower drive plates 39 to move downward, the spring 43 is compressed, the rack 40 begins to mesh with the gear 41, the rack 40 drives the gear 41 to rotate, thereby rotating the handles 11 of the three groups of liquid cooling units, and all the mainboards 4 are installed or overhauled through the above principle.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
