Description

Technical Field

[0001] The present application relates to the field of liquid cooling, and in particular to a flexible cavity liquid cooling cabinet. Background Art

[0002] As computing power and performance requirements increase, and technologies such as AI, IoT, and machine learning advance, the temperature of data center infrastructure and IT equipment continues to rise. More computing means more energy, more energy means more heat, more heat means more cooling, and cooling consumes more energy, and so on.

[0003] Given the inefficiencies of traditional air cooling systems, coupled with sustainability-focused design goals, rising electricity costs, and technical demands for cooling CPUs and GPUs, the need for more efficient, lower-power cooling systems is clear.

[0004] Liquid cooling is an emerging technology in computer cooling that has the advantages of being able to handle greater power densities, running cleanly and quietly, and costing much less than traditional air cooling.

[0005] However, in current liquid cooling cabinets, due to the different heat dissipation amounts of different parts of the heat dissipation elements and the shielding of the heat dissipation elements themselves, the coolant may have a problem of local heat accumulation.

[0006] To address the problem of heat accumulation, the traditional method is generally to install a circulation pump inside the cabinet to accelerate the flow of coolant in the cabinet to achieve uniform temperature. However, the installation of a circulating pump will take up space, affecting the number of servers placed, and the circulating pump is inconvenient to install and maintain inside the cabinet. Summary of the invention

[0007] In order to improve the problem of heat accumulation, the present application provides a flexible cavity liquid cooling cabinet.

[0008] A flexible cavity liquid cooling cabinet provided in the present application adopts the following technical solution: a flexible cavity liquid cooling cabinet, comprising a frame and a flexible cabinet for accommodating a heat dissipation element; the frame comprises a placement rack for mounting the heat dissipation element and a support rack connected to the placement rack; the top of the flexible cabinet is open; the support rack is located outside the flexible cabinet, and the placement rack extends into the flexible cabinet from the opening; mounting parts are formed at both ends of the placement rack, and the support rack has a fixing part fixed to the mounting part.

[0009] By adopting the above technical solution, the coolant is injected into the flexible cabinet, and the server is immersed in the coolant through the placement rack. The flexible cabinet can be deformed and shaken through the outside or its own structure to make the internal coolant flow and improve heat accumulation. At the same time, because the placement rack and the flexible cabinet are independently arranged, the service cabinet on the placement rack will not be affected when the flexible cabinet is deformed.

[0010] Optionally, the opening of the flexible cabinet has edging formed on two sides, and connecting edges formed at both ends of the opening; the mounting portion extends into the edging, and the fixing member simultaneously connects the edging and the mounting portion; the support frame includes a supporting surface supporting the edging and the connecting edge, and a sealing cover is provided at the opening, and the sealing cover abuts the edging and the connecting edge to seal the opening.

[0011] By adopting the above technical solution and the above method, the installation of the sealing cover can be facilitated. The supporting surface enables the sealing cover to press the edge and the connecting edge, and the edge and the connecting edge are deformed to improve the sealing effect.

[0012] Optionally, the support frame includes a support rod, the edging is provided with a connecting port that passes through the upper and lower parts, the support rod abuts the lower surface of the edging, the mounting portion is provided with a through hole, the top of the support rod is provided with a threaded hole, and the fixing part is a bolt, which passes through the connecting port, the through hole and the threaded hole to connect.

[0013] By adopting the above technical solution, the support frame is split into a support rod and a fixing piece, and the fixing piece is threadedly connected to the support rod, so that the placement frame can be quickly installed.

[0014] Optionally, a transition plate is provided on the upper surface of the edging, and a through hole is opened on the transition plate. After the bolt passes through the through hole, the bolt cap abuts against the upper surface of the transition plate.

[0015] By adopting the above technical solution, the setting of the transition plate increases the contact area with the edge, reduces the local extrusion of the bolt on the edge, and makes the edge less likely to be damaged.

[0016] Optionally, a sealing portion is formed on the upper surface of the edging, and an abutting portion abutting against the outer side of the sealing portion is formed on the transition plate.

[0017] By adopting the above technical solution, the setting of the abutting portion restricts the sealing portion from moving outward, so that the sealing portion can only contact with the sealing cover.

[0018] Optionally, the support rod is a telescopic rod, and a plurality of support rods are provided. The plurality of support rods on the same side share an adjusting device, and the adjusting device synchronously adjusts the heights of the support rods on the same side.

[0019] By adopting the above technical solution, by setting the support rod as a telescopic rod, the height of the support surface can be adjusted, so that the flexible cabinet has two optional states: suspended and touching the ground (the bottom of the flexible cabinet is in contact with the ground or other base); according to the heat generation of the heat dissipation element, the suspended state is selected if more heat is generated. The sides and the ground of the suspended flexible cabinet can be deformed, and there is an additional bottom surface for heat dissipation.

[0020] Optionally, the rack also includes a support base located at the bottom of the flexible cabinet, the support base forms a plurality of spaced grooves, the bottoms of the support rods on the same side are connected through a bottom plate, a cross bar is placed in the groove, and the height of the cross bar is consistent with the height of the groove.

[0021] By adopting the above technical solution, the base is used in conjunction with the telescopic rod. When the cross bar is located in the groove, the upper surface of the cross bar is flush with the upper surface of the base, and the flexible cabinet is in a ground-touching state. Another way is to remove the cross bar so that the bottom of the flexible cabinet partially touches the ground, and a driving device is set in the groove. This way takes into account the heavy weight of the coolant and uses partial ground contact to balance the force on the flexible cabinet.

[0022] Optionally, a driving device is installed on the frame, and the driving device intermittently pushes the outer surface of the flexible cabinet to deform the flexible cabinet.

[0023] By adopting the above technical solution, the flexible cabinet is driven to deform through an external driving device.

[0024] Optionally, the flexible cabinet is made of heat-deformable material.

[0025] Since the temperature of the coolant is different at different heights (the temperature difference between different layers of liquid is about 2-3°, which can be applied to heat dissipation fields such as single-phase immersion and two-phase immersion), the flexible cabinet is subjected to different thermal deformation at different positions. At the same time, the temperature in the coolant is constantly changing, which causes the flexible cabinet to continuously deform. The internal coolant shakes with the deformation of the flexible cabinet, improving the problem of heat accumulation inside the coolant.

[0026] A flexible cavity liquid cooling cabinet comprises a flexible cabinet for accommodating a heat dissipation element and a placement rack located in the flexible cabinet, wherein the placement rack is located at the bottom of the flexible cabinet.

[0027] This method has a simpler structure. The placement rack is integrally formed in the flexible cabinet and is made of a rigid material, generally stainless steel.

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

[0029] 1. The present application sets the cabinet to be flexible. Due to the uneven heat distribution of the liquid in the cabinet, the external force can be applied to the heat transfer liquid in the cabinet through the deformation of the flexible material under the action of temperature difference, thereby promoting the flow of the heat transfer liquid inside, thereby increasing the convective heat transfer effect between the internal heat transfer liquids.

[0030] 2. The external driving device drives the flexible cabinet to deform, thereby driving the internal coolant flow to improve the internal heat accumulation problem;

[0031] 3. Since the cabinet is set to be flexible, there is no place to install the server in the conventional way, so an independent rack structure is set up for installing the server;

[0032] 4. By improving the structure of the flexible cabinet, it is convenient to install the sealing cover to ensure that the internal coolant is clean, and single-phase and two-phase coolants can be used. It can also be used for cooling by spraying, immersion, and cold plate cooling methods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-12 This application is described in further detail.

[0047] The embodiment of the present application discloses a flexible cavity liquid refrigerator.

[0048] Embodiment 1: A flexible cavity liquid refrigerator, such as Figure 1 , including a rack, a flexible cabinet 1 for accommodating a heat dissipation element; the rack includes a placement rack 2 for installing the heat dissipation element, and a support rack 3 connected to the placement rack 2; the top of the flexible cabinet 1 is open. Figure 6 The two ends of the placement frame 2 form a mounting portion 21, and an L-shaped plate 22 is provided between the two mounting portions 21. The L-shaped plate 22 is provided with a hanging hole 23, and the fixed hook on the server can be hung on the hanging hole 23. The support frame 3 has a fixing member 4 fixed to the mounting portion 21.

[0049] The support frame 3 is located outside the flexible cabinet 1, and the placement frame 2 extends from the opening into the flexible cabinet 1. The fixing member 4 can be a bolt, which is threadedly connected to the placement frame 2. This method generally adopts an open method (that is, the opening is not closed). Since the support frame 3 and the flexible cabinet 1 are separately arranged, and the support frame 3 and the placement frame 2 are made of rigid materials, specifically stainless steel, they can bear the weight of the server.

[0050] In order to allow the coolant inside the flexible cabinet 1 to flow and improve heat accumulation, one way is to process the flexible cabinet 1 as a whole with a heat-deformable material. The heat-deformable material is generally a rubber material, which expands when heated, and is formed by an integral injection molding process. Fig.12The second method is based on the first method. An annular hoop 10 is installed at different heights of the flexible cabinet 1. The hardness of the hoop 10 is harder than that of the rubber material. For example, the hoop 10 is made of hard plastic, stainless steel or copper, and the spacing between adjacent hoops 10 may not be fixed (or fixed), and the heights of adjacent hoops 10 may not be the same (the heights may also be the same). In this way, a greater deformation of the rubber material part can be achieved. At the same time, stainless steel or copper materials are more conducive to heat conduction. The hoop 10 is placed in a way that it is directly covered (it can be completely covered or partially covered) in the rubber.

[0051] The third method is to install a driving device 5 on the frame, and the driving device 5 intermittently pushes the outer surface of the flexible cabinet 1 to deform the flexible cabinet 1. The driving device 5 can be a hydraulic cylinder, a cylinder, an electric cam, an electric push rod, etc. The driving device 5 can be installed on the side of the flexible cabinet 1 or on the bottom. In this embodiment, since there is no overhead support at the bottom of the flexible cabinet 1 and there is no installation position at the bottom, the driving device 5 is set on the side of the flexible cabinet 1. Specifically, the electric cam includes a motor 51 and an eccentric wheel 52. The motor 51 drives the eccentric wheel 52 to rotate and abut against the side wall of the flexible cabinet 1. Of course, the number of eccentric wheels 52 needs to be set according to the situation. One method is to set multiple eccentric wheels 52, each eccentric wheel 52 with an independent motor 51. Another method is to use a connecting rod to connect the eccentric wheels 52 in series, and the motor 51 drives the connecting rod to rotate through a gear set. Generally, the latter is used more.

[0052] Embodiment 2: A flexible cavity liquid cooling cabinet comprises a frame, a flexible cabinet 1 for accommodating a heat dissipation element; the frame comprises a placement rack 2 for mounting the heat dissipation element, and a support rack 3 connected to the placement rack 2; the top of the flexible cabinet 1 is open; the support rack 3 is located outside the flexible cabinet 1, and the placement rack 2 extends into the flexible cabinet 1 from the opening; mounting portions 21 are formed at both ends of the placement rack 2, and the support rack 3 has a fixing member 4 fixed to the mounting portion 21.

[0053] The opening of the flexible cabinet 1 forms a rim 11 on both sides, and a connecting edge 12 is formed at both ends of the opening, wherein the cross section of the rim 11 is C-shaped, the mounting portion 21 extends into the rim 11, and the fixing member 4 connects the rim 11 and the mounting portion 21 at the same time. The rim 11 includes a first connecting portion 111, a second connecting portion 112, and a third connecting portion 113 connected thereby, the first connecting portion 111 is connected to the body of the flexible cabinet 1, the second connecting portion 112 is perpendicular to the first connecting portion 111, and the third connecting portion 113 is parallel to the first connecting portion 111. The spacing between the upper surface of the first connecting portion 111 and the lower surface of the third connecting portion 113 is slightly greater than the height of the mounting portion 21, which can be understood as a gap between the mounting portion 21 and the lower surface of the third connecting portion 113 in the absence of the fixing member 4, and the gap is generally set to about 2 mm. The upper surface of the first connecting portion 111 is flush with the upper surface of the connecting edge 12. The length of the first connection portion 111 is greater than that of the second connection portion 112 . Both ends of the first connection portion 111 protrude from the second connection portion 112 . The third connection portion 113 is equal in length to the second connection portion 112 .

[0054] The support frame 3 includes a support surface for supporting the edging 11 and the connecting edge 12, and a sealing cover 6 is provided at the opening, and the sealing cover 6 abuts against the edging 11 and the connecting edge 12 to seal the opening. Specifically, the support frame 3 includes a support rod 31, and a connecting port 13 that passes through the edging 11 from top to bottom is provided. The upper surface of the support rod 31 serves as a support surface abutting against the lower surface of the edging 11, and the connecting port 13 is smaller than the upper surface of the support rod 31. When installed, the lower surface of the support rod 31 is directly opposite to the connecting port 13, and the connecting port 13 is generally a square hole, slightly larger than the diameter of the bolt. A through hole 211 is provided on the mounting portion 21, and a threaded hole 311 is provided on the top of the support rod 31. The fixing member 4 is a bolt, and the bolt passes through the connecting port 13, the through hole 211 and the threaded hole 311 for connection.

[0055] Further optimization, a transition plate 7 is provided on the upper surface of the edge 11 (third connection portion 113), and the transition plate 7 is larger than the area of ​​the connection port 13. A through hole is provided on the transition plate 7, and after the bolt passes through the through hole, the bolt cap abuts against the upper surface of the transition plate 7. A sealing portion 14 is formed on the upper surface of the edge 11 (third connection portion 113), and an abutting portion 71 abutting against the outer side of the sealing portion 14 is formed on the transition plate 7.

[0056] In this embodiment, a plurality of support rods 31 are arranged at the corresponding edges 11 on both sides of the opening, and the specific number of support rods 31 on each side is the same as the number of the placement racks 2. A U-shaped connecting rod 32 is connected between the two outermost support rods 31 on each side, and the upper surface of the U-shaped connecting rod 32 is flush with the upper surface of the support rod 31. The U-shaped connecting rod 32 mainly serves as a support surface for the connecting edge 12, and also partially serves as a support surface for the lower surface of the first connecting portion 111. On the basis of the support surface, the sealing cover 6 abuts against the first connecting portion 111 and the connecting edge 12 by its own weight and squeezes and seals. At the same time, the sealing cover 6 abuts against the end surfaces of the second connecting portion 112 and the third connecting portion 113.

[0057] like Figure 7 The sealing cover 6 is in an I-shaped shape when viewed from above. Specifically, the sealing cover 6 includes an upper cover portion 61, side cover portions 62 located on both sides of the upper cover portion 61, and end cover portions 63 located at both ends of the upper cover portion 61. The sealing cover 6 is also made of stainless steel. The side cover portion 62 abuts against the inner wall of the sealing portion 14, the length of the end cover portion 63 is greater than the length of the upper cover portion 61, and both ends of the end cover portion 63 extend out of the upper cover portion 61. The lower end surface of the end cover portion 63 abuts against the upper surface of the first connecting portion 111 and the connecting edge 12, and the two ends of the end cover portion 63 extend out of the upper cover portion 61 and abut against the end surfaces of the second connecting portion 112 and the third connecting portion 113 to close the two ends of the edge 11.

[0058] It should be additionally explained that the sealing cover 6 may not be provided in this embodiment.

[0059] like Figure 3-5 In order to adapt to the flexible cabinets 1 of different heights, the support rod 31 is set as a telescopic rod, and considering the overall movement, a bottom plate 34 is installed at the bottom of the support rod 31, and the bottom plate 34 is connected to the support rod 31 on the same side. The support rod 31 can be an electric push rod or the like to achieve automatic telescopic extension. However, the manual height adjustment structure adopted in this scheme is that the support rod 31 includes an upper rod body 312 and a lower rod body 313. A cavity 3121 is provided below the upper rod body 312, and the lower rod body 313 is partially inserted into the cavity 3121. A screw rod 314 is rotatably connected in the lower rod body 313, and a threaded groove 3131 is provided on the lower rod body 313, and the screw rod 314 is threadedly connected to the threaded groove 3131.

[0060] An outer frame 8 is fixed to multiple support rods 31 on the same side, and a worm 84 is connected to the outer frame 8 for horizontal rotation. A worm wheel 81 meshing with the worm 84 is connected to the outer frame 8 for rotation. A first bevel gear 82 is coaxially fixed to the worm wheel 81, and a second bevel gear 83 is fixed to the screw 314. The first bevel gear 82 meshes with the second bevel gear. In the above case, one worm 84 is used, and the number of the worm wheel 81, the first bevel gear 82 and the second bevel gear 83 is consistent with the number of the placement rack 2. The worm wheel 81 and the worm 84 are self-locking and quickly adjusted in height.

[0061] like Figure 8The frame also includes a support base 9 located at the bottom of the flexible cabinet 1, and the support base 9 forms a plurality of grooves 91 arranged at intervals. A crossbar 33 is placed in the groove 91, and the height of the crossbar 33 is consistent with the height of the groove 91.

[0062] Since the support rod 31 is a telescopic rod, the height of the flexible cabinet 1 can be adjusted. When the cross bar 33 is located exactly in the groove 91, the upper surface of the support seat 9 is flush with the upper surface of the cross bar 33, and the bottom of the flexible cabinet 1 is in contact with the support seat 9. At this time, the bottom of the flexible cabinet 1 generally does not deform, but the side wall deforms.

[0063] When the height of the flexible cabinet 1 is relatively high, the support base 9 is spaced apart from the bottom of the flexible cabinet 1, and the driving device 5 can be installed in the groove 91 of the support base 9. Therefore, the above two modes can be adjusted.

[0064] Another way is to take out the cross bar 33, but the bottom of the flexible cabinet 1 is in contact with the upper surface of the support seat 9, and the driving device 5 can also be installed in the groove.

[0065] Installation process: Slide the mounting portion 21 of the placement rack 2 into the opening at the end of the edge 11. Each mounting portion 21 of the placement rack 2 corresponds to a support rod 31. Place the transition plate 7 on the third connection portion 113. Bolts are passed through the transition plate 7, the third connection portion 113, the mounting portion 21, the first connection portion 111 and the threaded hole 311 on the support rod 31 at one time (the bolts are not tightened at this time). Then hang the server on the placement rack 2 and cover it with the sealing cover 6, so that the side cover portion 62 abuts against the inner wall of the sealing portion 14, the lower end face of the end cover portion 63 abuts against the first connection portion 111 and the upper surface of the connecting edge 12, and the end cover portion 63 extends out of the two ends of the upper cover portion 61 and abuts against the end faces of the second connection portion 112 and the third connection portion 113 to close the two ends of the edge 11. Then, the bolts are turned again to squeeze the package 11. Due to the gap between the mounting portion 21 and the lower surface of the third connecting portion 113, the third connecting portion 113 will tilt downward, so the sealing portion 14 is squeezed toward the side cover portion 62, and the bolts will also squeeze the third connecting portion 113 along the length direction of the third connecting portion 113 through the transition plate 7, so that the end of the edge 11 is further abutted against the end cover portion 63.

[0066] Example 3: Fig.11 A flexible cavity liquid cooling cabinet comprises a flexible cabinet 1 for accommodating a heat dissipation element, and a placement rack 2 located in the flexible cabinet 1, wherein the placement rack 2 is located at the bottom of the flexible cabinet 1. The above-mentioned cabinet is produced by an integral injection molding method. After the placement rack 2 is directly placed in the mold, the rubber material is directly injected so that the flexible cabinet 1 and the placement rack 2 are connected as a whole. In this method, the bottom of the flexible cabinet 1 is generally not suspended. The placement rack 2 is U-shaped as a whole, and hanging holes 23 are provided on both sides of the placement rack 2. The server is located in the U-shape.
