Description

[0001] This application is a divisional application of Chinese invention patent application filed on January 18, 2021, with application number 202110060886.9 and invention title "Rotary Distributor for Liquid-Cooled Cabinet and Liquid-Cooled Cabinet". Technical Field

[0002] This invention relates to the field of liquid cooling technology, and more particularly to a rotary distributor for liquid cooling cabinets and a liquid cooling cabinet. Background Technology

[0003] Electronic devices typically require heat dissipation when they are in operation due to the heat they generate.

[0004] For example, a single-phase immersion liquid cooling method has been applied, in which electronic equipment is placed in a liquid-cooled cabinet with upper and lower inlets and outlets. The coolant enters from the inlet located at the lower end of the cabinet and immerses the electronic equipment from bottom to top, and then flows out from the outlet located at the upper end of the cabinet. In this way, the coolant exchanges heat with the electronic equipment in the circulation flow, thereby dissipating heat from the electronic equipment.

[0005] However, in the above-mentioned scheme, the coolant usually enters from one side of the liquid-cooled cabinet. At this time, for the same horizontal position, the heat dissipation between electronic devices or between different positions of the same electronic device is not uniform. In order to maintain the overall heat dissipation requirements of electronic devices, the existing technology usually needs to increase the cooling capacity of the coolant, which results in a waste of resources. Summary of the Invention

A dispensing outlet is provided between a first end and a second end of the dispensing arm, and the dispensing outlet is located on the side of the dispensing arm opposite to the direction of rotation. In this way, when the distribution chamber rotates around its central axis, the coolant flows into the distribution chamber and then flows out from the distribution outlet that rotates with the distribution chamber. By rotating the coolant outlet, the coolant can be more evenly heated in the rotating area covered by the rotating distribution arm. It can be understood that at this time, the evenly heated coolant can dissipate heat evenly between electronic devices or between different locations of the same electronic device, improving the uniformity of liquid cooling heat dissipation. This solves the technical problem of resource waste caused by uneven liquid cooling heat dissipation, and achieves the technical effect of improving the uniformity of liquid cooling heat dissipation of electronic devices and reducing resource waste.

[0017] In this embodiment of the present disclosure, the liquid distribution chamber is provided with a liquid distribution inlet at one end facing away from the second direction, and a liquid inlet sub-pipe is connected to the liquid distribution inlet. The liquid inlet sub-pipe is connected to the liquid inlet main pipe, and the liquid inlet main pipe is also connected to the liquid inlet located at the bottom of the liquid cooling cabinet. Furthermore, the axis of the liquid inlet tube coincides with the central axis, so that the liquid dispensing chamber rotates around the liquid inlet tube in the first direction.

[0033] To better understand the above technical solutions, exemplary embodiments of this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0034] This application provides a rotary distributor for a liquid-cooled cabinet. The rotary distributor includes a dispensing chamber 10 and dispensing arms 30. The dispensing chamber 10 has a central axis 11 and rotates around the central axis 11 in a first direction. A plurality of dispensing arms 30 are evenly distributed around the dispensing chamber 10 in the circumferential direction relative to the central axis 11. The dispensing arms 30 rotate with the dispensing chamber 10. The first end of the dispensing arm 30 is connected to the dispensing chamber 10, and the second end of the dispensing arm 30 is closed. Furthermore, a dispensing outlet 31 is provided between the first end and the second end of the dispensing arm 30. The dispensing outlet 31 is located on the side of the dispensing arm 30 facing away from the first direction, that is, the instantaneous flow direction of the coolant flowing out of the dispensing outlet 31 is opposite to the first direction. The dispensing outlet 31 is used to allow the coolant flowing into the dispensing chamber to flow out of the rotary distributor.

[0035] In this embodiment, see Figure 1 The rotary distributor includes a dispensing chamber with an internal space for containing coolant. The dispensing chamber is rotatable about a central axis, for example, see [reference needed]. Figure 1 , 2 The liquid separation chamber rotates around its central axis along the first direction C1 ( Figure 1 Rotate counterclockwise (in the middle); then, along this central axis, at one end of the dispensing chamber ( Figure 2 The lower part of the cavity has a liquid inlet, and multiple liquid dispensing arms are evenly distributed around its circumference. One end of each dispensing arm is connected to the receiving space of the dispensing cavity, and the other end is closed. Furthermore, a liquid outlet is provided between the two ends of each dispensing arm, located on the side of the dispensing arm facing away from the first direction. See [reference needed]. Figure 1 In the multiple dispensing arms, the dispensing outlet is located on the side of the corresponding dispensing arm opposite to the rotation direction C1. Thus, it can be understood that when the dispensing arm rotates with the dispensing chamber, the rotating dispensing arm forms a rotating area, and the coolant flowing out from the dispensing outlet can be evenly distributed in this rotating area, so that the coolant can evenly dissipate heat to the electronic equipment located in the rotating area.

[0036] In this embodiment, the rotary distributor is used in a liquid cooling cabinet; specifically, it can be combined with... Figure 8 , 9 The liquid-cooled cabinet is, for example, square in shape. The liquid-cooled cabinet 60 has a liquid inlet 61 at the bottom and a liquid outlet 62 at the top. The heat dissipation area 64 of the liquid-cooled cabinet 60 houses electronic equipment to be cooled. Coolant flows into the distribution area 63 from the liquid inlet at the bottom, then gradually rises from bottom to top and absorbs the heat of the electronic equipment, and then flows out from the liquid outlet at the top. It is then cooled by external refrigeration equipment, and so on. Specifically, in this embodiment, the rotary distributor should be located in the distribution area 63 at the bottom of the liquid-cooled cabinet, and the distribution inlet 20 is connected to the liquid inlet 61 of the liquid-cooled cabinet. Coolant flows into the rotary distributor from the liquid inlet through the distribution inlet, and then flows out from the rotating distribution outlet, thereby achieving the effect of uniform distribution of coolant in the above-mentioned rotating area. The uniformly distributed coolant gradually rises from bottom to top and absorbs the heat of the electronic equipment, thus providing uniform heat dissipation for the electronic equipment.

[0037] Understandably, to ensure a uniform distribution of coolant in the aforementioned rotating region, a distribution outlet should be provided on the distribution arm as needed (see [reference]). Figure 1 and Figure 3 The location and number of liquid outlets on the liquid dispensing arm should be determined by actual needs or the structure of the liquid cooling cabinet.

[0038] Understandably, multiple rotary distributors should be evenly distributed across the cross-section of the liquid cooling cabinet along the coolant flow direction (see [reference]). Figure 8 and Figure 9 Furthermore, the length of the dispensing arm of each rotary dispenser can be determined according to actual needs.

[0039] This application provides a rotary distributor for a liquid-cooled cabinet and a liquid-cooled cabinet. The rotary distributor includes a dispensing chamber, a dispensing inlet, and dispensing arms disposed in the dispensing chamber. The dispensing chamber rotates around its central axis. The dispensing inlet is located at one end of the dispensing chamber along the central axis. Multiple dispensing arms are evenly distributed around the circumference of the dispensing chamber, i.e., the dispensing arms rotate with the dispensing chamber. Then, a dispensing outlet is provided between the first and second ends of the dispensing arms, and the dispensing outlet is located on the side of the dispensing arm opposite to the direction of rotation. In this way, when the distribution chamber rotates around its central axis, the coolant flows into the distribution chamber from the distribution inlet and then flows out from the distribution outlet that rotates with the distribution chamber. By rotating the coolant outlet, the coolant can be more evenly heated in the rotating area covered by the rotating distribution arm. It can be understood that at this time, the evenly heated coolant can dissipate heat evenly between electronic devices or between different locations of the same electronic device, improving the uniformity of liquid cooling heat dissipation. This solves the technical problem of resource waste caused by uneven liquid cooling heat dissipation, and achieves the technical effect of improving the uniformity of liquid cooling heat dissipation of electronic devices and reducing resource waste.

[0040] In this embodiment, for ease of understanding, the rotation of the liquid distribution chamber around the central axis can be achieved by external driving units such as a drive motor, which can drive the liquid distribution chamber to rotate at a constant speed. The rotation speed of the liquid distribution chamber can be determined according to actual needs. Alternatively, the liquid distribution chamber can be driven to rotate by the reverse thrust of the coolant flowing out. Then, the liquid distribution chamber and the liquid distribution arm are subjected to the resistance of the coolant when rotating. When the resistance and the reverse thrust are in balance, the liquid distribution chamber is in a state of uniform rotation.

[0041] In this embodiment, for ease of understanding, the liquid outlet is located in the opposite direction of the liquid distribution arm to the first direction of rotation of the liquid distribution arm. This facilitates the flow of coolant from the liquid outlet and also facilitates the full and uniform distribution of coolant within the aforementioned rotation area.

[0042] In one possible implementation, the dispensing outlet 31 includes at least a first dispensing outlet 311 located at the first end of the dispensing arm 30.

[0043] That is, in this embodiment, if the liquid distribution chamber rotates at a constant speed by being driven by an external drive motor or the like, in order to ensure the uniform distribution of coolant in the rotating area of ​​the liquid distribution arm, it is understood that at least a first liquid distribution outlet should be provided on the liquid distribution arm, and the first liquid distribution outlet should be as close as possible to the liquid distribution chamber to ensure the uniform distribution of coolant at the center of the rotating area.

[0044] In one possible implementation, the liquid dispensing outlet 31 includes at least a first liquid dispensing outlet 311 located at the first end of the liquid dispensing arm 30 and a second liquid dispensing outlet 312 located at the second end of the liquid dispensing arm 30.

[0045] That is, in this embodiment, if the liquid distribution chamber rotates due to the reverse thrust of the coolant flowing out, then refer to... Figure 1 At least two distribution outlets should be provided on the distribution arm, one close to the distribution chamber and the other far away from the distribution chamber. In this case, the coolant flowing out from the second distribution outlet far from the distribution chamber exerts a larger torque on the rotating distributor, which can generate a larger rotational driving force. Meanwhile, the coolant flowing out from the first distribution outlet close to the distribution chamber can simultaneously ensure the uniformity of the coolant flowing out above the rotation area of ​​the distribution arm. In other words, in this embodiment, by setting the first and second distribution outlets as described above, the uniformity of the coolant flowing out above the rotation area of ​​the distribution arm can be ensured while ensuring the rotation of the distribution chamber, thus eliminating the need for an external drive unit.

[0046] In addition, see Figure 3 Other liquid separation outlets may be provided as needed between the first liquid separation outlet 311 and the second liquid separation outlet 312.

[0047] Regarding the rotation of the distribution chamber due to the reverse thrust of the coolant flowing out, please refer to [the relevant documentation / reference]. Figure 1 and Figure 4 For example, when coolant is sprayed out from the distributor outlet, according to the law of conservation of momentum, the coolant generates a reverse thrust on the distributor outlet. This reverse thrust then acts on the distributor arm. The direction of the reverse thrust is opposite to the flow direction of the coolant. This reverse thrust causes the distributor arm to drive the distributor cavity to generate a rotational effect around the central axis. The rotational effect is quantified by torque, which is equal to the force multiplied by the distance of the force. This torque causes the distributor arm to obtain an angular acceleration around the central axis. As the distributor arm accelerates in the coolant (the distributor cavity rotates together), the resistance of the distributor arm to the coolant and the resistance of the distributor cavity also increase. Moreover, the direction of these two resistances is opposite to the direction of the reverse thrust. That is, the two resistances will generate a rotational effect opposite to the reverse thrust. When these three rotational effects are in balance, the distributor cavity and the distributor arm rotate at a constant speed.

[0048] Therefore, the farther the second liquid outlet is from the liquid distribution chamber, the greater the reverse thrust it generates; and the total reverse thrust obtained by the rotary liquid distributor should be obtained by the superposition of multiple liquid outlets on multiple liquid distribution arms. In addition, the final rotation state of the rotary liquid distributor is determined by the number of liquid distribution arms, the state of the coolant, the number and position of liquid outlets on each liquid distribution arm, etc.

[0049] In one possible implementation, when the dispensing chamber 10 and the dispensing arm 30 rotate at a constant speed, the rotational linear velocity of the second dispensing outlet 312 along the first direction is not less than the flow velocity of the coolant.

[0050] In this embodiment, the number of the dispensing arm and the dispensing outlet should be set such that when the dispensing chamber and the dispensing arm rotate at a constant speed, the rotational linear velocity of the dispensing outlet on the dispensing arm that is farthest from the dispensing chamber should not be less than the flow velocity of the coolant. This can prevent coolant from accumulating at the dispensing outlet and improve the uniformity of coolant distribution.

[0051] In the above embodiments, regarding the liquid distribution outlet 31, it can be understood that the liquid distribution outlet 31 can be directly opened on the liquid distribution arm 30, or, in one possible embodiment, a first diversion port 32 is opened between the first end and the second end of the liquid distribution arm 30, and a liquid distribution sub-tube 33 is connected to the outside of the first diversion port 32 relative to the liquid distribution arm 30, and the liquid distribution outlet 31 is located at the outer end of the liquid distribution sub-tube 33; wherein, the axis of the liquid distribution sub-tube 33 is set at a predetermined angle with the axis of the liquid distribution arm 30.

[0052] That is, in this embodiment, combined with Figure 1 , Figure 4 A branched sub-tube can be installed on the dispensing arm. One end of the sub-tube is connected to the first branch port on the dispensing arm, and the dispensing outlet is located at the other end of the sub-tube. Through the gathering effect of the sub-tube on the coolant, the spray area of ​​the coolant can be expanded, and the area of ​​uniform heat dissipation of the coolant can be increased.

[0053] Furthermore, the axis of the dispensing sub-tube and the axis of the dispensing arm are set at a predetermined angle; this is understandable, please refer to... Figure 5 At this time, the dispensing tube can be located on a cone surface E or cone surface F at a predetermined angle with the axis of the dispensing arm as the central axis. Furthermore, in conjunction with the fact that the dispensing outlet is located on the side of the dispensing arm opposite to the first direction, the dispensing tube should be located in the region of cone surface E or cone surface F in the negative direction of the X-axis.

[0054] It should be understood that, regarding the aforementioned predetermined angle, when a dispensing arm is provided with multiple dispensing sub-tubes, the predetermined angles corresponding to the multiple dispensing sub-tubes may be the same, or the predetermined angles corresponding to the multiple dispensing sub-tubes may be different.

[0055] Furthermore, in one possible implementation, on the same dispensing sub-tube 33, the dispensing outlet 31 is inclined relative to the first dispensing port 32 toward the second end of the dispensing arm 30.

[0056] In this embodiment, combined with Figure 1 Relative to the rotating area of ​​the dispensing arm, such as the rotating plane, the opening of the dispensing sub-tube (i.e., the dispensing outlet) is arranged radially outward, thus increasing the spray area of ​​the coolant; that is, combined with Figure 5 The dispensing tube 33 should be located in the region where the conical surface F is in the negative direction of the X-axis.

[0057] Furthermore, in one possible implementation, the rotary distributor is located at the bottom of the liquid cooling cabinet 60, with the central shaft 11 positioned in the direction from the bottom to the top of the liquid cooling cabinet 60; and on the same dispensing sub-tube 33, the dispensing outlet 31 is inclined relative to the first diversion port 32 toward the top of the liquid cooling cabinet 60.

[0058] In this embodiment, combined with Figure 5 , 8 Relative to the rotating area of ​​the dispensing arm, such as the rotating plane, the opening of the dispensing sub-tube (i.e., the dispensing outlet) is oriented towards the top of the liquid cooling cabinet 60; that is, the orientation of the dispensing outlet 31 is opposite to the flow direction of the coolant in the liquid cooling cabinet. Figure 8 The direction of C2 is the same, which reduces the circulation resistance of the coolant; that is, combined with Figure 5 The dispensing tube 33 should be located in the region where the conical surface F is in the positive direction of the Z-axis.

[0059] In summary, combining the above and Figure 5 It should be understood that, with the first branch port as the origin O, the rotational tangent direction of the first branch port is the X-axis, that is, the tangent direction of C1 is the X-axis, the axial direction of the dispensing arm is the Y-axis, the positive direction of the Y-axis is radially outward, and the direction of the central axis of the dispensing chamber is the Z-axis, the positive direction of the Z-axis is the circulating flow direction of the coolant C2. Therefore, in the above coordinate system, firstly, the spatial angle of the dispensing sub-tube should have a negative X-axis component to ensure that the dispensing outlet is located on the side of the dispensing arm opposite to the first direction; secondly, the spatial angle of the dispensing sub-tube should have a positive Y-axis component to expand the spray area of ​​the coolant; and thirdly, the spatial angle of the dispensing sub-tube should have a positive Z-axis component to reduce the circulation resistance of the coolant.

[0060] In one possible implementation, the cross-section of the dispensing chamber 10 is circular along the direction of the central axis 11; and / or, the cross-section of the dispensing arm 30 is elliptical along the axial direction of the dispensing arm 30, with the minor axis of the ellipse parallel to the central axis 11 of the dispensing chamber 10.

[0061] In this embodiment, the liquid separation chamber is cylindrical. Then, refer to... Figure 6 The dispensing arm is elliptical, with the minor axis of the ellipse parallel to the central axis of the dispensing chamber. This reduces frictional resistance during rotation and increases the rotational speed of the dispensing chamber when it is in equilibrium.

[0062] Furthermore, along the axial direction of the dispensing sub-tube, the cross-section of the dispensing sub-tube can also be set to an ellipse, with the minor axis of the ellipse parallel to the central axis 11 of the dispensing chamber 10.

[0063] In one possible implementation, a plurality of second diversion ports 12 are evenly distributed circumferentially around the liquid distribution chamber 10 relative to the central axis 11, and the first end of the liquid distribution arm 30 is connected to the second diversion port 12; the plurality of second diversion ports 12 are centrally symmetrically distributed circumferentially around the liquid distribution chamber 10 relative to the central axis 11; the first end of the liquid distribution arm 30 is detachably connected to the second diversion port 12; and the rotary liquid distributor also includes a diversion cover 13, which is used to close the second diversion port 12 that is not connected to the liquid distribution arm 30.

[0064] For details, please refer to [link / reference]. Figure 7 That is, multiple second diversion ports can be provided around the circumference of the liquid distribution chamber. Then, the first end of the liquid distribution arm is connected to the second diversion port, for example by insertion or threading. In this way, the liquid distribution arms can be detachably connected, and different numbers of liquid distribution arms can be connected to the liquid distribution chamber according to actual needs. Furthermore, the second diversion ports without connected liquid distribution arms can be closed by the diversion cap. In addition, the multiple second diversion ports can be centrally symmetrically distributed relative to the central axis.

[0065] Based on the above description of the first diversion port, it can be seen that the coolant first flows from the distribution chamber through multiple second diversion ports into different distribution arms; then, in the same distribution arm, the coolant flows out of the rotary distributor from the distribution arm through multiple first diversion ports.

[0066] In one possible implementation, the rotary distributor is located at the bottom of the liquid cooling cabinet 60, and the central axis 11 is arranged in a second direction from the bottom to the top of the liquid cooling cabinet 60; multiple rotary distributors are evenly arranged in a plane perpendicular to the second direction.

[0067] That is, combining Figure 8 , 9 Depending on the actual situation, multiple rotary distributors can be installed inside the liquid cooling cabinet, wherein multiple rotary distributors are perpendicular to the second direction C2 ( Figure 8 The liquid coolant is evenly distributed in a plane (vertical direction), and this second direction is the direction from the bottom to the top of the liquid coolant cabinet, or the second direction is the direction of circulation of the coolant in the liquid coolant cabinet.

[0068] Specifically, a liquid inlet 20 is provided on the liquid distribution chamber 10. The liquid inlet 20 is located at one end of the liquid distribution chamber facing away from the second direction. A liquid inlet sub-pipe 40 is connected to the liquid distribution inlet 20. The liquid inlet sub-pipe 40 is connected to the liquid inlet main pipe 50. The liquid inlet main pipe 50 is also connected to the liquid inlet 61 located at the bottom of the liquid cooling cabinet 60. Furthermore, the axis of the liquid inlet sub-pipe 40 coincides with the central axis 11, so that the liquid distribution chamber 10 can rotate around the liquid inlet sub-pipe 40 in the first direction.

[0069] In other words, for example, the liquid inlet is located at the end of the liquid distribution chamber opposite to the direction of coolant circulation. The liquid inlet is connected to the main liquid inlet via a sub-pipe, and multiple rotary distributors can be connected to the main liquid inlet. Then, the main liquid inlet is connected to the liquid inlet of the liquid cooling cabinet. In this way, the coolant flows from the inlet through the main liquid inlet and the sub-pipe into the liquid distribution chamber, flows from the liquid distribution chamber through the rotating liquid outlet into the liquid distribution area 63, and then gradually rises from the liquid distribution area 63 to the heat dissipation area 64, and finally flows out from the outlet, thus circulating.

[0070] This application also discloses a liquid-cooled cabinet, the bottom of which is provided with an inlet 61 for the coolant to circulate in, and the top of which is provided with an outlet 62 for the coolant to circulate out; at the bottom of the liquid-cooled cabinet 60, the inlet 61 is connected to a distributor, which is the aforementioned rotary distributor.

[0071] In one possible implementation, the liquid-cooled cabinet 60 includes a side wall, and an overflow return tank 65 is provided on the outer side of the top of the side wall so that the coolant overflows from the top of the side wall and flows into the overflow return tank 65. The outlet 62 is located at the lower end of the overflow return tank 65.

[0072] See Figure 8 That is, a double-layer overflow return tank is provided on the top outer side of the side wall of the liquid cooling cabinet, and an outlet is provided at the lower end of the overflow return tank; in this way, when the liquid cooling cabinet is full of coolant, the coolant overflows from the side wall of the liquid cooling cabinet and flows into the overflow return tank at the same time, and finally flows to the external refrigeration equipment from the outlet at the lower end of the overflow return tank.

[0073] In this embodiment, the overflow return tank provides a space for sufficient contact and heat exchange of the coolant return, improving the temperature uniformity of the coolant return, which in turn helps external refrigeration equipment to uniformly cool the coolant, improves refrigeration efficiency, and further increases the circulation speed of the coolant and the heat dissipation speed of electronic equipment.

[0074] In one possible implementation, the overflow return tank 65 circumferentially surrounds at least three sidewalls; or, The liquid-cooled cabinet 60 is rectangular and includes a pair of first sidewalls and second sidewalls. The length of the first sidewall is greater than the length of the second sidewall. The overflow return tank 65 is located on the outside of the first sidewall.

[0075] That is, combining Figure 9 The liquid cooling cabinet can typically be a square structure with the overflow return tank circumferentially surrounding three side walls; or, the liquid cooling cabinet can be a cube with the overflow return tank circumferentially surrounding four side walls; or, the liquid cooling cabinet can be a cuboid, and if the lengths of the two side walls of the cuboid differ significantly, then the overflow return tank should be located on the outside of the two long side walls.

[0076] In this embodiment, the coolant that has absorbed the heat from the electronic equipment can overflow into the overflow return tank with the shortest possible distance, which is beneficial for the hotter coolant to quickly and centrally leave the liquid cooling cabinet.
