[0003] However, in the above-mentioned liquid cooling cabinet, since some areas are blocked by other factors, there is a problem of local heat accumulation in the cabinet. Summary of the invention

[0004] In order to improve the problem of energy consumption, the present application provides a cabinet that can reduce local heat accumulation.

[0005] The present application provides a cabinet capable of reducing local heat accumulation, which adopts the following technical solution: a cabinet capable of reducing local heat accumulation, comprising a cabinet and a cooling liquid circulation system, wherein at least part of the cabinet is a flexible structure, and the cabinet capable of reducing local heat accumulation also comprises a driving device for driving the flexible structure to deform so as to make the cooling liquid in the cabinet flow. The driving device comprises a mounting base, a cam, a driving member for driving the cam to rotate, a connecting member connected to the outer wall of the cabinet, and a resetting member installed on the connecting member for resetting, wherein the connecting member and the cam are kept in contact under the action of the resetting member.

[0006] A partition is installed in the cabinet to divide the cabinet into a first chamber and a second chamber. The first chamber is used to install the server. The top of the partition is spaced from the lower end surface of the cabinet top to form an overflow space. The first chamber is filled with coolant. The liquid outlet of the coolant circulation system is connected to the first chamber, and the liquid return end is connected to the second chamber. The driving device includes a guide plate on one side of the partition, the height of the guide plate is lower than the upper end surface of the partition, a reflux hole is provided on the guide plate, and the reflux hole is connected to a reflux pipe extending downward. A pressure relief valve is installed in the reflux pipe, and a buffer space is formed at the upper end of the pressure relief valve in the reflux pipe. When the buffer space is full of coolant, the pressure relief valve opens. A rotatable water wheel shaft is provided below the reflux pipe. The first chamber part is a flexible structure, and the water wheel shaft is connected to the flexible structure by a rope.

[0007] A partition is installed in the cabinet to divide the cabinet into a first chamber and a second chamber. The first chamber is used to install the server. The top of the partition is spaced from the lower end surface of the cabinet top to form an overflow space. The first chamber is filled with coolant. The liquid outlet of the coolant circulation system is connected to the first chamber, and the liquid return end is connected to the second chamber. The driving device includes a guide plate on one side of the partition, the height of the guide plate is lower than the upper end surface of the partition, a reflux hole is provided on the guide plate, and the reflux hole is connected to a reflux pipe extending downward. A pressure relief valve is installed in the reflux pipe, and a buffer space is formed at the upper end of the pressure relief valve in the reflux pipe. When the buffer space is full of coolant, the pressure relief valve opens. A rotatable water wheel shaft is provided below the reflux pipe, and the water wheel shaft is connected to a stirring device through a transmission assembly. The stirring device is located in the first chamber.

[0008] By adopting the above technical solution, the coolant flows from the overflow space into the return pipe. Due to the presence of the pressure relief valve, the coolant will not flow in temporarily and will slowly accumulate in the buffer space. When the pressure relief value of the pressure relief valve is exceeded, the pressure relief valve opens, and the coolant flows down quickly to impact the water wheel shaft, driving the water wheel shaft to rotate. The water wheel shaft is connected to the stirring device through the transmission assembly. Since the pressure relief valve is set, it will release pressure at intervals. This method can make the coolant in the buffer space flow out at once in a short period of time, and its impact is stronger.

[0009] Optionally, the stirring device includes a rope and stirring members spaced apart on the rope, one end of the rope has an elastic section, and the elastic section is fixedly connected to the inner wall of the first chamber.

[0010] By adopting the above technical solution, the rope is pulled, and the rope moves to drive the stirring member to move in the coolant, so that the coolant is pushed and mixed by the stirring member, and the elastic section is used to reset the rope after it moves.

[0011] Optionally, the stirring member is in a truncated cone shape, and a cross section of an end surface of the stirring member away from the elastic section is larger than an end surface close to the elastic section, and a groove is provided on the end surface of the stirring member away from the elastic section.

[0012] By adopting the above technical solution, when the pressure is released, the end surface with a large cross-section moves toward the partition plate, which can bring more coolant. After the pressure is released, the side wall of the truncated cone structure has the function of dispersing the water flow, and the elastic section is easier to recover.

[0013] Optionally, the transmission assembly includes a pulley block, the pulley block includes a fixed pulley, a movable pulley and a transmission rope, one end of the transmission rope is fixed to the water wheel shaft, and the other end passes around the fixed pulley and the movable pulley and is installed on the lower end surface of the cabinet top, and the end of the rope away from the elastic section is connected to the movable pulley.

[0014] By adopting the above technical solution, the water wheel shaft is driven to rotate by the power during pressure relief, and the pulley group has the function of increasing the load, which can make the elastic section stretch longer and make the stirring member larger, which is conducive to the flow and mixing of the coolant.

[0015] Optionally, the stirring device further comprises a guide wheel, wherein the guide wheel is a guide wheel capable of adjusting height, and the rope passes around the guide wheel.

[0016] By adopting the above technical solution, the direction of the stirring device can be changed.

[0017] Optionally, the connection point between the liquid return end of the circulation system and the second chamber is located below the water wheel shaft, and during pressure relief, it is ensured that the liquid level in the second chamber is not higher than the height of the water wheel shaft.

[0018] By adopting the above technical solution, if the coolant in the second chamber cannot be pumped out in time, the coolant in the second chamber will hit the water wheel shaft. Due to the resistance of the coolant, the number of rotations of the water wheel shaft will be affected during subsequent pressure relief.

[0019] Optionally, the circulation system includes an inlet pipe, an outlet pipe, a circulation pump and a radiator, one end of the inlet pipe is connected to the radiator, and the other end is connected to the first chamber, one end of the outlet pipe is connected to the radiator, and the other end is connected to the second chamber, and the circulation pump is installed on the outlet pipe.

[0020] Optionally, the pressure relief valve includes a sealing plate rotatably connected to the return pipe via a rotating shaft, a torsion spring is installed on the rotating shaft, and the rotating shaft is a damping rotating shaft.

[0021] By adopting the above technical solution, the rotating shaft is first set as a damping rotating shaft. When it releases pressure, it needs to overcome the combined force of the damping rotating shaft and the torsion spring. Therefore, more coolant can be stored in the buffer space. When the sealing plate is opened, the impact force is stronger. More importantly, the damping element can make the sealing plate recover slowly after opening, so that the coolant in the storage space has enough time to fall.

[0022] Optionally, the stirring device includes a stirring shaft rotatably connected to the first chamber, and one end of the stirring shaft is sealed and passes through the partition plate to the second chamber; the transmission assembly includes a first bevel gear fixed on the water wheel shaft, and a second bevel gear fixed on the stirring shaft, and the first bevel gear and the second bevel gear are meshed.

[0023] The stirring shaft is driven by a bevel gear transmission, and the stirring shaft drives the coolant to flow and mix. This method does not require high sealing between the stirring shaft and the partition plate. Even if a small amount of coolant flows into the second chamber through the gap between the stirring shaft and the hole on the partition plate, it does not matter.

[0024] Optionally, a fan is provided on the top of the cabinet, and the fan faces the guide plate.

[0025] By adopting the above technical solution, the setting of the guide plate allows the coolant to be spread out, and the cooling can be accelerated by the fan.

[0026] Optionally, the cabinet includes a metal frame and an elastic rubber plate sealed and connected to the metal frame.

[0027] By adopting the above technical solution, the elastic rubber layer will also deform when the coolant flows, further driving the mixing of the coolant. The metal frame mainly provides support and installation of parts.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The cabinet is at least partially configured as a flexible structure, and the flexible structure is deformed by a driving device, so that the coolant in the cabinet can flow and avoid local heat accumulation;

[0030] 2. The cabinet is set up with an integrated flexible structure, which has good sealing performance and is lighter than ordinary stainless steel structure;

[0031] 3. In this embodiment, the water wheel shaft is driven to rotate by the power of the coolant reflux, and the water wheel shaft drives the stirring device through the transmission assembly, without the need for additional power, thereby reducing energy consumption;

[0032] 4. The cooling water in the one-time falling buffer space separated by water storage has a stronger impact force and the water wheel shaft rotates faster than continuous flow. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-9 This application is described in further detail.

[0045] Embodiment 1: The embodiment of the present application discloses a cabinet capable of reducing local heat accumulation, comprising a cabinet 1 and a cooling liquid circulation system.

[0046] A partition plate 2 is installed in the cabinet 1 to divide the cabinet 1 into a first chamber 3 and a second chamber 4. The top of the partition plate 2 is spaced from the lower end surface of the top of the cabinet 1 to form an overflow space 7. The first chamber 3 is filled with a coolant, which can be a single-phase liquid or a two-phase liquid. In this embodiment, a one-way liquid is preferred, specifically Novec7100 / 7100DL or Novec71IPA produced by 3M Company, wherein the boiling point of Novec7100 / 7100DL is 61°C, and the boiling point of Novec71IPA is 55°C. Specifically, the cabinet 1 is composed of a cabinet body 5 and a lid 6. The top of the cabinet body 5 is open, and one side of the lid 6 is hinged to the top of the cabinet body 5, so that it is convenient to open the lid 6 to place the server 37 in the first chamber 3. The partition plate 2 is fixed in the cabinet body 5, and the upper surface of the partition plate 2 is lower than the upper surface of the cabinet body 5, so that when the lid 6 is closed, an overflow space 7 is formed between the upper surface of the partition plate 2 and the lower surface of the lid 6.

[0047] The liquid outlet of the cooling liquid circulation system is connected to the first chamber 3, and the liquid return end is connected to the second chamber 4; the specific circulation system includes a liquid inlet pipe 8, a liquid outlet pipe 9, a circulation pump 10 and a radiator 11, one end of the liquid inlet pipe 8 is connected to the radiator 11, and the other end is connected to the first chamber 3, one end of the liquid outlet pipe 9 is connected to the radiator 11, and the other end is connected to the second chamber 4, and the circulation pump 10 is installed on the liquid outlet pipe 9. The radiator 11 is a cold row, and the specific structure can refer to the water cooling row structure disclosed in CN219574756U. Since the cold row is a conventional technology, it will not be repeated in this embodiment.

[0048] A guide plate 12 is provided on one side of the partition plate 2. The guide plate 12 is located in the second chamber 4 and seals the top opening of the second chamber 4. The guide plate 12 is lower than the upper end surface of the partition plate 2. The guide plate 12 includes an inclined portion 13 and a horizontal portion 14. A fan 36 is installed on the cover 6, and the fan 36 faces the guide plate 12.

[0049] A reflux hole 16 is provided on the horizontal portion 14, and a reflux pipe 17 extending downward is connected to the reflux hole 16. A pressure relief valve 15 is installed in the reflux pipe 17, and a buffer space is formed at the upper end of the pressure relief valve 15 in the reflux pipe 17, and the pressure relief valve 15 opens when the buffer space is filled with coolant. In this solution, the reflux hole 16 is a square hole, and the corresponding reflux pipe 17 is configured as a square pipe. Although the ordinary pressure relief valve 15 can also play a role, in order to achieve better results, the present application additionally designs a pressure relief valve 15, which includes a sealing plate 18 rotatably connected to the return pipe 17 through a rotating shaft 34, and a torsion spring 19 is installed on the rotating shaft 34. One end of the torsion spring 19 is fixed to the sealing plate 18, and the other end is connected to the side wall of the return pipe 17. The rotating shaft 34 is a damping rotating shaft. The rotating shaft 34 passes through the through hole on the sealing plate 18, so that the sealing plate 34 can rotate relative to the rotating shaft 34. The damping rotating shaft can be understood as a rubber sleeve fixed on the outer shell of the metal rotating shaft 34, and the rubber sleeve is frictionally matched with the through hole on the sealing plate 18.

[0050] A rotatable water wheel shaft 20 is provided below the return pipe 17. The water wheel shaft 20 is connected to the stirring device through a transmission assembly. The stirring device is located in the first chamber 3. Specifically, the water wheel shaft 20 includes a fixed shaft 21 and an impeller 22 fixed on the fixed shaft 21. Both ends of the fixed shaft 21 are rotatably connected in the second chamber 4 through bearings. The fixed shaft 21 is located below the return pipe 17 and deviates from the return pipe 17 in the horizontal direction, that is, the fixed shaft 21 is not located directly below the return pipe 17, but obliquely below. Part of the impeller 22 is located directly below the return pipe 17. When the coolant falls, the impeller 22 is impacted to drive the fixed shaft 21 to rotate.

[0051] The connection point between the return end of the circulation system and the second chamber 4 is located below the water wheel shaft 20, and the liquid level in the second chamber 4 is ensured not to be higher than the height of the water wheel shaft 20 during pressure relief. Therefore, it is best to set a liquid level gauge at the bottom of the second chamber 4, and control the operation of the circulation pump 10 through the liquid level gauge and the controller of the circulation system.

[0052] The stirring device is located in the active space 35 between the server and the side wall of the first chamber 3. The stirring device includes a rope 23, stirring members 24 spaced apart on the rope 23, one end of the rope 23 has an elastic section 25 (the rope 23 can also be directly made of an elastic rope 23 for easy processing), and the elastic section 25 is fixedly connected to the inner wall of the first chamber 3 (a fixing ring is welded on the inner wall of the first chamber 3 for tying the elastic section 25). The stirring member 24 is truncated cone-shaped, and the cross section of the end face of the stirring member 24 away from the elastic section 25 is larger than the end face close to the elastic section 25, and a truncated cone-shaped groove is provided on the end face of the stirring member 24 away from the elastic section 25. In this way, when the pressure is released, the end face of the stirring member 24 with a larger cross section moves toward the partition plate 2, which can drive more coolant, and when the pressure is released, due to the side wall of the truncated cone structure, it has the function of dispersing the water flow, and the elastic section 25 is easier to recover. The stirring member and rope are generally made of plastic materials that will not rust, such as PVC, PE, etc.

[0053] The transmission assembly includes a pulley group, which includes a fixed pulley 26, a movable pulley 28 and a transmission rope 27, wherein two fixed pulleys 26 are provided, which are respectively located on both sides of the partition plate 2 and close to the top of the partition plate 2, and one movable pulley 28 is provided. One end of the transmission rope 27 is fixed to the fixed shaft 21 (the transmission rope 27 can be directly tied to the fixed shaft 21), and the other end is fixed under the cover 6 after passing through the two fixed pulleys 26 and one movable pulley 28 (a fixing ring is provided on the cover 6, and a hook is provided at one end of the transmission rope 27, and the connection between the transmission rope 27 and the cover 6 is achieved by hanging the hook on the fixing ring), and the end of the rope 23 away from the elastic section 25 is connected to the shell of the movable pulley 28. Since the transmission rope 27 passes through the partition plate 2 (i.e., the partition plate 2 has a rope threading hole for the transmission rope 27 to pass through), a sealing rubber head 29 is fixed on the transmission rope 27. The sealing rubber head 29 is located in the second chamber 4. The sealing rubber head 29 is a truncated cone structure, and its small end cross section is smaller than the rope threading hole diameter, and its large end cross section is larger than the rope threading hole diameter. The sealing rubber head 29 is used to prevent the coolant from flowing from the first chamber 3 into the second chamber 4 when the pressure is not released.

[0054] Two limit plates can be fixed on the fixed shaft 21, so that the transmission rope 27 can only be wound between the two limit plates. In this solution, since the movable pulley 28 moves up and down in the coolant, a stirring piece can be fixed on the housing of the movable pulley 28 to further improve the coolant mixing ability, and the moving direction of the movable pulley 28 and the stirring piece 24 are perpendicular to each other, that is, the coolant can be mixed in two directions.

[0055] The stirring device also includes a guide wheel 30, which is a guide wheel 30 capable of adjusting the height, and the rope 23 is passed around the guide wheel 30. In this embodiment, the lower tangent point of the guide wheel 30 and the line connecting the connection point of the elastic section 25 and the first chamber 3 are horizontal, so the rope 23 between the guide wheel 30 and the elastic section 25 is horizontal, and the stirring member 24 moves horizontally. If the height of the guide wheel 30 changes, the rope 23 between the guide wheel 30 and the elastic section 25 can be tilted, and the moving direction of the stirring member 24 can be changed. In this embodiment, a plurality of installation positions (installation holes) of different heights are set in the first chamber 3, and the shaft of the guide wheel 30 can be inserted into different installation positions. Specifically, the shaft of the guide wheel 30 is interference fit with the installation hole, and the wheel of the guide wheel 30 rotates around the shaft of the guide wheel 30.

[0056] The implementation principle of a cabinet that can reduce local heat accumulation in the embodiment of the present application is as follows: the coolant flows into the return pipe 17 through the overflow space 7 and is blocked by the pressure relief valve 15, the coolant will not flow in temporarily, and will slowly accumulate in the buffer space. When the set pressure relief value of the pressure relief valve 15 is exceeded, the pressure relief valve 15 opens, and the coolant flows down quickly to impact the water wheel shaft 20, driving the water wheel shaft 20 to rotate. The rotation of the water wheel shaft 20 drives the transmission rope 27 to be wound around the fixed shaft 21 and pulls the movable pulley 28 upward, thereby pulling the rope 23 to move, driving the stirring member 24 on the rope 23 to move and promote the coolant to flow and mix, and at this time the elastic section 25 is stretched. After the pressure relief is completed, the elastic section 25 is reset.

[0057] Example 2: Figure 6-7 , which is different from Example 1, in this embodiment, an additional set of transmission components and stirring devices are provided, and the elastic section 25 is fixed to the partition plate 2, and the fixed pulley 26 located in the first chamber 3 is arranged away from the partition plate 2. The moving direction of the stirring member 24 in Example 2 is just opposite to the movement direction of the stirring member 24 in Example 1, so that the two sets of stirring devices can cooperate with each other to drive the coolant to move in the same direction.

[0058] Example 3: Figure 8 , which is different from Example 1, is that the stirring device includes a stirring shaft 31 rotatably connected to the first chamber 3, and one end of the stirring shaft 31 is sealed and passes through the partition plate 2 to the second chamber 4; the transmission assembly includes a first bevel gear 32 fixed on the fixed shaft 21, and a second bevel gear 33 fixed on the stirring shaft 31, and the first bevel gear 32 and the second bevel gear 33 are meshed.

[0059] Working process: The coolant flows into the return pipe 17 through the overflow space 7 and is blocked by the pressure relief valve 15. The coolant will not flow in temporarily and will slowly accumulate in the buffer space. When the set pressure relief value of the pressure relief valve 15 is exceeded, the pressure relief valve 15 opens, and the coolant flows down quickly to impact the water wheel shaft 20, driving the water wheel shaft 20 to rotate. The rotation of the water wheel shaft 20 drives the stirring shaft 31 through the bevel gear transmission. The stirring shaft 31 drives the coolant to flow and mix. This method does not require high sealing between the stirring shaft 31 and the partition plate 2. Even if a small amount of coolant flows into the second chamber 4 through the gap between the stirring shaft 31 and the hole on the partition plate 2, it does not matter.

[0060] In the embodiments 1-3, the entire cabinet is a metal cabinet (stainless steel), wherein the cabinet 5 connected to the elastic section 25 is a flexible structure. The flexible structure is generally an elastic rubber material (low-density polyethylene material).

[0061] Embodiment 4, on the basis of embodiment 3, a plurality of branch ropes are fixedly connected to each rope 23, and the branch ropes are connected to the inner wall of the flexible structure, and can actively pull the flexible structure to deform.

[0062] Embodiment 5: A cabinet capable of reducing local heat accumulation, wherein at least part of the cabinet is a flexible structure, and the cabinet capable of reducing local heat accumulation further comprises a driving device for driving the flexible structure to deform so as to allow the coolant in the cabinet to flow. Specifically, the cabinet 1 comprises an elastic rubber container 40 (made of low-density polyethylene), the elastic rubber container 40 is a flexible structure as a whole, and the top of the elastic rubber container 40 is open.

[0063] In order to support the elastic rubber container 40, a metal frame can be provided as an auxiliary device. The metal frame includes a bottom plate 38 and a vertical plate 39 fixed on the bottom plate 38. The vertical plate 39 is provided with a vertically extending strip hole 41. The strip hole 41 provides deformation space for the elastic rubber plate 40. The elastic rubber container 40 is directly placed in the metal frame. The metal frame can provide certain support for the elastic rubber container 40. The lid 6 is sealed on the elastic rubber container 40. The metal frame is not necessary. As another way to make the cabinet 1 at least partially a flexible structure, the cabinet 1 can be directly made into a cabinet 1 with a hard material and a flexible material separated in the height direction. Generally, the flexible material is still made of rubber, and the hard material is made of a formulated hard plastic. This hard plastic has better compatibility with rubber. Of course, the hard material can also be made of stainless steel.

[0064] The driving device includes a mounting base 42, a cam 48, a driving member driving the cam 48 to rotate, a connecting member connected to the outer wall of the cabinet 1, and a reset member installed on the connecting member to reset the cabinet 1. The connecting member and the cam 48 are kept in contact under the action of the reset member. The driving member can be a motor, the reset member is a spring 43, the connecting member includes a connecting rod 44, a connecting block 45, and a rotating wheel 46. The connecting block 45 is fixed to the elastic rubber container 40, one end of the connecting rod 44 is fixed to the connecting block 45, and the rotating wheel 46 is rotatably connected to the other end of the connecting rod 44. A connecting plate 47 is fixed to the mounting base 42, the connecting rod 44 passes through the connecting plate 47, and the spring 43 is fixed to the connecting plate 47 and the connecting block 45. The mounting base 42 is made of stainless steel SUS304.

[0065] A large amount of heat is generated when the server is working. Since the elastic rubber container 40 is flexible, the plastic deformation characteristics of the material cause thermal expansion and contraction, and the cavity expands. The motor starts to drive the cam 48 to rotate. The cam 48 rotates to the near point and abuts against the rotating wheel 46. The spring 43 is compressed. The cam 48 is used for support to prevent the elastic rubber container 40 from cracking due to excessive thermal expansion. The cam 48 rotates to the far point and abuts against the rotating wheel 46. The spring 43 is reset. The thrust of the cam 48 is used to return the soft elastic rubber container 40 to its original state, and the thrust generated causes the liquid inside the elastic rubber container 40 to shake, thereby quickly dissipating heat.
