Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid cooling heat dissipation, and particularly relates to a single-phase immersion liquid cooling cabinet. BACKGROUND

[0002] The immersion liquid cooling cabinet cools the electronic equipment through circulating cooling liquid.

[0003] The lower end of the liquid cooling cabinet is provided with an inlet of cooling liquid, the upper end is provided with an outlet of cooling liquid, and the electronic equipment is arranged in the liquid cooling cabinet, so that the cooling liquid with low temperature flows into the electronic equipment from the inlet at the lower end and immerses the electronic equipment, absorbs heat of the electronic equipment, and then flows out from the outlet at the upper end, and then exchanges heat with an external heat source through a pipeline, and after cooling, flows into the liquid cooling cabinet from the inlet, so as to realize the liquid cooling heat dissipation of the electronic equipment through circulation.

[0004] However, in the prior art, the inlet and outlet of the liquid cooling cabinet are connected with the heat source through a pipeline, the system design is limited, the diameter of the pipeline is much smaller than the cross-sectional area of the liquid cooling cabinet, which makes the circulation flow rate of the cooling liquid in the liquid cooling cabinet low, the cooling liquid is in a laminar flow state, and the heat exchange performance between the cooling liquid and the electronic equipment is poor, which seriously reduces the liquid cooling heat dissipation effect of the electronic equipment.

[0058] In order to better understand the above technical solutions, the example embodiments of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and not all embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein.

[0059] The submerged liquid cooling cabinet cools the electronic equipment by circulating cooling liquid.

[0060] The common submerged liquid cooling cabinet is designed as an open-top container with a certain volume, please refer to Figure 1 , which can install multiple electronic equipment and contains insulating cooling liquid. The liquid cooling cabinet is provided with a cooling liquid inlet 61 at the bottom and a cooling liquid outlet 62 at the top. The low-temperature cooling liquid is discharged from the cabinet after heat exchange with the electronic equipment, and then circulated through the pipeline to the heat exchanger 65 for heat exchange with the external cold source, and then circulated through the pipeline to the cooling liquid inlet of the liquid cooling cabinet after cooling.

[0061] However, in the aforementioned liquid-cooled cabinets, considering the pressure drop and pipe diameter of the coolant circulation pipeline, the coolant velocity within the pipeline is generally around 1–2 m / s, and the circulation flow rate is typically designed based on a 5–15°C temperature difference between the inlet and outlet, according to the total heat generation. The cross-sectional area of ​​a standard-sized liquid-cooled cabinet is more than 100 times the cross-sectional area of ​​the circulation pipeline. This results in a very low coolant circulation velocity within the cabinet; that is, the velocity of the coolant flowing from the bottom to the top within the cabinet is extremely low, on the order of 10 m / s. -2 In addition, the viscosity of conventional insulating coolant is relatively high, about 7 to 40 times that of water. At this time, the coolant in the liquid-cooled cabinet is in a laminar flow state, which has poor convective heat transfer performance and a large temperature difference between the coolant and the heat-generating components of electronic equipment, which seriously reduces the liquid cooling heat dissipation effect of electronic equipment.

[0062] To address the aforementioned issues, this application discloses a single-phase immersion liquid-cooled cabinet. The cabinet includes two double-layered storage spaces. By embedding an external cold source within the cabinet and allowing coolant to flow through it via overflow, the coolant's circulation flow rate and velocity are increased. This alters the coolant's flow state (from laminar to turbulent), improving its convective heat transfer performance, reducing the temperature difference between the coolant and electronic equipment, and ultimately enhancing the liquid cooling effect on the electronic equipment.

[0063] like Figure 2 As shown, in this embodiment, the liquid-cooled cabinet 60 includes a first housing and a second housing. The first housing forms a first accommodating space 71, which extends along a second direction (e.g., ...). Figure 2 A power drive device 77 is provided at the first end of the first housing (in the C2 direction); a second housing is provided on the circumferential outer side of the first housing along the second direction, and a second accommodating space 72 is formed between the second housing and the first housing; wherein, the first accommodating space 71 is used to carry electronic equipment, and the second accommodating space 72 is used to carry heat exchanger device 78; the first end of the first accommodating space 71 along the second direction is connected to the second accommodating space 72 through the power drive device 77, and the second end of the first accommodating space 71 along the second direction is connected to the second accommodating space 72 through an opening, so that coolant circulates between the first accommodating space 71 and the second accommodating space 72.

[0064] Please refer to Figure 2 , 3 The first housing includes, for example, a base plate and sidewalls, and the first housing forms a first receiving space, which is located along a second direction ( Figure 2 The first end (in the C2 direction) Figure 2 The middle and bottom ends are equipped with a power drive device, and the second end ( Figure 2The second shell is arranged on the circumferential outer side of the first shell, so that the second accommodating space is formed between the first shell and the second shell, and the two accommodating spaces are communicated, for example, through cooling liquid communication holes which are communicated to the inlet of the power driving device; in this way, the electronic equipment is placed in the first accommodating space, and the heat exchanger device is placed in the second accommodating space, and at this time, the cooling liquid can flow in circulation between the two accommodating spaces under the driving of the power driving device.

[0065] Firstly, in the first accommodating space, the cooling liquid absorbs heat from the electronic equipment and overflows into the second accommodating space, and it can be understood that the cooling liquid can overflow from the end of the first shell when the first accommodating space is filled with the cooling liquid, and the flow of the cooling liquid from the first accommodating space to the second accommodating space is large; secondly, in the second accommodating space, the cooling liquid with large flow can be cooled and heat-exchanged by the heat exchanger device while falling, and then flows back to the first accommodating space through the multiple communicated cooling liquid communication holes; thereby increasing the circulation flow of the cooling liquid, improving the circulation flow rate of the cooling liquid, and further enhancing the liquid cooling heat dissipation effect of the cooling liquid on the electronic equipment.

[0066] The embodiment of the present application provides a single-phase immersion liquid cooling cabinet, which comprises a first shell and a second shell, the first shell is formed with a first accommodating space, the first accommodating space is provided with a power driving device at one end (bottom end) along a second direction and is open at the other end (top end), then, the second shell is arranged on the circumferential outer side of the first shell along the second direction, so that the second accommodating space is formed between the first shell and the second shell, wherein the first accommodating space is used for carrying electronic equipment, and the second accommodating space is used for carrying a heat exchanger device; and the two accommodating spaces are communicated through multiple cooling liquid communication holes which are communicated to the inlet of the power driving device; in this way, the cooling liquid can flow in circulation between the two accommodating spaces to liquid cool and heat dissipate the electronic equipment in the first accommodating space.

[0067] Specifically, in the first accommodating space, the cooling liquid flows out from the power driving device, then gradually immerses the electronic equipment, and after absorbing the heat of the electronic equipment, the cooling liquid overflows from the opening of the first shell into the second accommodating space; in the process of flowing downward in the second accommodating space, the cooling liquid which is high in temperature after absorbing heat exchanges heat with the heat exchanger device, releases heat and reduces in temperature; then, the cooling liquid flows into the power driving device from the cooling liquid communication hole, so as to flow in circulation, thereby realizing liquid cooling and heat dissipation of the electronic equipment.

[0068] That is, in the cooling liquid circulation process, on the one hand, the cooling liquid flows from the first accommodating space to the second accommodating space, and the flow of the cooling liquid is large; on the other hand, the two accommodating spaces are communicated through the plurality of cooling liquid communication holes; that is, the external cooling source is built-in the liquid cooling cabinet, the two accommodating spaces are double-layered, and one end is overflowed and the other end is communicated, thereby solving the technical problem that the liquid cooling heat dissipation effect is poor when the cooling liquid is connected with the external cooling source through the pipeline; through the above arrangement, the circulation flow rate of the cooling liquid is increased, the convective heat transfer performance of the cooling liquid is improved, and the liquid cooling heat dissipation effect of the cooling liquid on the electronic equipment is improved.

[0069] In the embodiment, the power driving device should be a power driving device for driving the cooling liquid to flow, such as a driving pump, and the power driving device should have an inlet and an outlet of the cooling liquid, for example, referring to Figure 2 The power driving device can be placed in the first accommodating space as a whole, so that the cooling liquid directly flows from the outlet of the power driving device to the first accommodating space, or it can be understood that the plurality of cooling liquid communication holes correspond to the inlets of the plurality of power driving devices, and then the outlets of the power driving devices are communicated to the first accommodating space.

[0070] In one possible implementation, the first shell includes a first side wall 73 extending in the second direction, the second shell includes a second side wall 74 extending in the second direction, and the second accommodating space 72 is formed between the first side wall 73 and the second side wall 74; wherein the first side wall 73 and the second side wall 74 are connected with a bearing plate 75, and the bearing plate 75 is provided with a cooling liquid communication hole 76.

[0071] Specifically, the first shell and the second shell respectively include a first side wall and a second side wall, and the two side walls are arranged in parallel and extend in the second direction, so that the second accommodating space is formed between the two side walls; then, the two side walls are also connected through a bearing plate, and the bearing plate is provided with a cooling liquid communication hole for the cooling liquid to flow; that is, please refer to Figure 2 The upper end of the bearing plate is the second accommodating space, and the lower end of the bearing plate is the first accommodating space, that is, the cross section of the first accommodating space is T-shaped with the bottom end protruding outward, and the bearing plate is arranged perpendicular to the second direction, so that the cooling liquid is conveniently returned to the first accommodating space by gravity.

[0072] In one possible implementation, the cross section of the first shell relative to the second direction is square or rectangular, and the second accommodating space 72 is arranged on the outer side of at least one side wall of the first shell.

[0073] In this embodiment, the liquid cooling cabinet is generally cuboid structure, in order to make the cooling liquid overflow to the second accommodating space with the shortest stroke and combine with the actual needs, the second accommodating space is arranged outside at least one side wall of the first shell.

[0074] That is, for example, the cross section of the first shell relative to the second direction is square, at this time, because the stroke of the cooling liquid overflowing from any side wall is similar, combined with the actual needs, Figure 4 the second accommodating space is circumferentially around the first accommodating space, that is, the second accommodating space is arranged outside the four side walls of the first shell, which maximizes the flow of the cooling liquid;

[0075] For example, the cross section of the first shell relative to the second direction is rectangular, at this time, because the stroke of the cooling liquid overflowing from the longer side wall is shorter, combined with the actual needs, Figure 3 the second accommodating space is circumferentially around the first accommodating space, that is, the second accommodating space can be arranged outside the three side walls of the first shell (two longer side walls and one shorter side wall); or, according to the actual needs, combined with Figure 5 the second accommodating space can also be arranged outside the two longer side walls of the first shell; or, according to the actual needs, the second accommodating space can also be arranged outside the one longer side wall of the first shell.

[0076] In one possible implementation, the power driven device 77 includes a cooling liquid circulating pump; the heat exchanger device 78 includes heat exchange pipes, which are laid in the second accommodating space 72 along the plane perpendicular to the second direction.

[0077] It can be understood that the power driven device should be a device for driving the flow of the cooling liquid, such as a cooling liquid circulating pump; then, the heat exchanger device should be a device for cooling the cooling liquid, for example, the heat exchanger device includes heat exchange pipes, which are finned heat exchange pipes, and the finned heat exchange pipes flow through refrigerant, so that the cooling liquid can exchange heat with the heat exchange pipes during the falling process, thereby being cooled; combined with Figure 2 , 3 the heat exchange pipes can be laid in the second accommodating space along the plane perpendicular to the second direction, so that in the falling direction of the cooling liquid, the heat exchange pipes are arranged in layers, which maximizes the contact area of the cooling liquid with the heat exchange pipes, and improves the cooling efficiency of the cooling liquid.

[0078] In one possible implementation, the outlet of the power driven device 77 is communicated with a plurality of rotating distributors 79, and the plurality of rotating distributors 79 are uniformly distributed on the cross section of the first accommodating space 71 relative to the second direction.

[0079] That is, referring to Figure 2 , 3For example, the first accommodating space includes a heat dissipation area 64 at the upper end and a liquid distribution area 63 at the lower end. The heat dissipation area is used to place electronic equipment. Then, on the cross section of the liquid distribution area relative to the coolant flow direction (i.e., the second direction C2), the first accommodating space 71 is evenly distributed with a plurality of rotating liquid distributors 79. The rotating liquid distributors 79 are connected to the main liquid inlet pipe 50 through the liquid inlet sub-pipe 40, and then the main liquid inlet pipe 50 is connected to the power drive device 77.

[0080] The evenly distributed multiple rotating distributors 79 enable the cooled liquid to be evenly distributed in the distribution zone, thereby improving the uniformity of liquid cooling heat dissipation in electronic equipment.

[0081] In one possible embodiment, the rotary distributor includes a dispensing chamber 10, a dispensing inlet 20, and dispensing arms 30. The dispensing chamber 10 has a central axis 11 along a second direction, and the dispensing chamber 10 rotates about 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, with a first end connected to the dispensing chamber 10 and a second end of the dispensing arm 30 being closed. The dispensing inlet 20 is located at one end of the dispensing chamber 10 along the central axis 11 and is used to connect to the outlet of a power drive device. Furthermore, a dispensing outlet 31 is provided between the first and second ends of the dispensing arms 30, located on the side of the dispensing arm 30 facing away from the first direction. The dispensing inlet 20 is used to allow coolant to flow into the rotary distributor, and the dispensing outlet 31 is used to allow coolant to flow out of the rotary distributor.

[0082] In this embodiment, see Figure 6 The rotary distributor includes a dispensing chamber with an internal space for containing coolant. The dispensing chamber is rotatable about a central axis, which is positioned along a second direction, for example, see [reference needed]. Figure 6 , 7 The liquid separation chamber rotates around its central axis along the first direction C1 ( Figure 6 Rotate counterclockwise (in the middle); then, along this central axis, at one end of the dispensing chamber ( Figure 7 A liquid-dispensing inlet is provided at the lower middle end, which is used to connect with the outlet of the power drive device. Multiple liquid-dispensing arms are evenly distributed circumferentially around the liquid-dispensing chamber. One end of each liquid-dispensing arm is connected to the receiving space of the liquid-dispensing chamber, and the other end of the liquid-dispensing arm is closed. Furthermore, a liquid-dispensing outlet is provided between the two ends of each liquid-dispensing arm, located on the side of the liquid-dispensing arm facing away from the first direction; that is, see... Figure 6, the liquid distribution outlets of the plurality of liquid distribution arms are arranged on the side of the liquid distribution arms opposite to the rotation direction C1. In this way, when the plurality of liquid distribution arms rotate simultaneously with the liquid distribution cavity, the rotating liquid distribution arms form a rotating area perpendicular to the flow direction of the cooling liquid, and the cooling liquid flowing out of the liquid distribution outlets can be uniformly distributed in the rotating area. In addition, the plurality of rotating liquid distributors are uniformly distributed in the first accommodation space, so that the cooling liquid can be uniformly distributed in the cross section perpendicular to the second direction, thereby uniformly liquid-cooling and dissipating heat from the electronic device.

[0083] It can be understood that, in order to uniformly distribute the cooling liquid in the rotating area, the positions and number of the liquid distribution outlets on the liquid distribution arms should be arranged as required (see Figure 6 and Figure 8 ). That is, the positions and number of the liquid distribution outlets on the liquid distribution arms should be determined according to actual needs or the structure of the liquid cooling cabinet.

[0084] It can be understood that, a plurality of rotating liquid distributors 79 should be uniformly arranged on the cross section of the liquid cooling cabinet 60 along the flow direction of the cooling liquid (see Figure 3 ). In addition, the length of the liquid distribution arms of each rotating liquid distributor can be determined according to actual needs.

[0085] The rotating liquid distributor of the embodiment includes a liquid distribution cavity, a liquid distribution inlet and liquid distribution arms arranged on the liquid distribution cavity. The liquid distribution cavity rotates around a central axis, the liquid distribution inlet is arranged at one end of the liquid distribution cavity along the central axis, and a plurality of liquid distribution arms are uniformly distributed on the circumferential direction of the liquid distribution cavity, that is, the liquid distribution arms rotate with the liquid distribution cavity. Then, a liquid distribution outlet is arranged between the first end and the second end of the liquid distribution arm, and the liquid distribution outlet is located on the side of the liquid distribution arm opposite to the rotation direction.

[0086] In this way, when the liquid distribution cavity rotates around the central axis, the cooling liquid flows into the inside of the liquid distribution cavity from the liquid distribution inlet and then flows out of the liquid distribution outlet rotating with the liquid distribution cavity. By rotating the outlet of the cooling liquid, the cooling liquid can be better uniformly tempered in the rotating area covered by the rotating liquid distribution arms. It can be understood that, at this time, the uniformly tempered cooling liquid uniformly dissipates heat from the electronic devices or different positions of the same electronic device, thereby improving the uniformity of liquid cooling heat dissipation and achieving the technical effects of improving the uniformity of liquid cooling heat dissipation of the electronic device and reducing resource waste.

[0087] In the embodiment, for the convenience of understanding, the rotation of the liquid distribution cavity around the central axis can be driven by an external driving unit such as a driving motor, and the speed of the rotation of the liquid distribution cavity can be determined according to actual needs. Alternatively, the liquid distribution cavity can also be driven to rotate by the reverse thrust when the cooling liquid flows out. Then, the liquid distribution cavity and the liquid distribution arms are subjected to the resistance of the cooling liquid when rotating. When the resistance and the reverse thrust are in balance, the liquid distribution cavity is in a uniform rotation state.

[0088] In this embodiment, for the convenience of understanding, the distribution outlet is located at the side of the distribution arm opposite to the first direction of rotation of the distribution arm, so that the outflow of the cooling liquid from the distribution outlet is facilitated, and the uniform distribution of the cooling liquid in the above-mentioned rotating plane is facilitated.

[0089] In one possible implementation, the distribution outlet 31 comprises at least a first distribution outlet 311 located at the first end of the distribution arm 30.

[0090] That is, in this embodiment, if the distribution cavity rotates at a constant speed by the driving of an external driving motor or the like, in order to ensure the uniform distribution of the cooling liquid in the rotating area of the distribution arm, it can be understood that at least one first distribution outlet should be provided on the distribution arm, and the first distribution outlet should be as close as possible to the distribution cavity to ensure the uniform distribution of the cooling liquid at the center of the above-mentioned rotating area.

[0091] In one possible implementation, the distribution outlet 31 comprises at least a first distribution outlet 311 located at the first end of the distribution arm 30 and a second distribution outlet 312 located at the second end of the distribution arm 30, and the linear rotational speed of the second distribution outlet 312 when rotating at a constant speed in the first direction is not less than the flow speed of the cooling liquid.

[0092] That is, in this embodiment, if the distribution cavity rotates by the reverse thrust when the cooling liquid flows out, referring to Figure 6 , at least two distribution outlets should be provided on the distribution arm, one of which is close to the distribution cavity, and the other of which is away from the distribution cavity; at this time, the cooling liquid flowing out of the second distribution outlet away from the distribution cavity has a larger torque on the rotating distributor, which can generate a larger rotational driving force, and the cooling liquid flowing out of the first distribution outlet close to the distribution cavity can ensure the uniformity of the outflow of the cooling liquid above the rotating area of the distribution arm; that is, in this embodiment, by providing the above-mentioned first distribution outlet and the second distribution outlet, the uniformity of the outflow of the cooling liquid above the rotating area can be ensured while the distribution cavity rotates, and the setting of an external driving unit can be omitted.

[0093] In addition, referring to Figure 8 , other distribution outlets can also be provided between the above-mentioned first distribution outlet 311 and the second distribution outlet 312 as needed.

[0094] Regarding the rotation of the distribution cavity by the reverse thrust when the cooling liquid flows out, please refer to Figure 6 and Figure 9For example, when the coolant is sprayed from the distribution outlet, according to the law of conservation of momentum, the coolant generates a reverse thrust to the distribution outlet, and the reverse thrust further acts on the distribution arm. The direction of the reverse thrust is opposite to the flow direction of the coolant. The reverse thrust causes the distribution arm to rotate the distribution cavity around the central axis. The rotation effect is quantified as torque, which is equal to force multiplied by the distance of force. The torque causes the distribution arm to obtain angular acceleration around the central axis. As the distribution arm accelerates in the coolant (the distribution cavity rotates together), the resistance of the distribution arm and the resistance of the distribution cavity increase, and the direction of the sum of the two resistances is opposite to the direction of the reverse thrust, i.e. the two resistances generate a rotation effect opposite to the reverse thrust. When the three rotation effects are balanced, the distribution cavity and the distribution arm rotate at a constant speed.

[0095] Therefore, the farther the second distribution outlet is from the distribution cavity, the greater the reverse thrust it generates. The total reverse thrust obtained by the rotating distributor should be superimposed by the plurality of distribution outlets on the plurality of distribution arms. Furthermore, the final rotating state of the rotating distributor is determined by the number of distribution arms, the state of the coolant, the number and position of the distribution outlets on each distribution arm, etc.

[0096] In this embodiment, the number of distribution arms and distribution outlets should be set such that when the distribution cavity and the distribution arm rotate at a constant speed, the rotational linear speed of the distribution outlet on the distribution arm farthest from the distribution cavity should be not less than the flow rate of the coolant. In this way, the accumulation of coolant at the distribution outlet position can be prevented, and the uniformity of the distribution of the coolant is improved.

[0097] In the above embodiment, regarding the distribution outlet 31, it can be understood that the distribution outlet 31 can be directly provided on the distribution arm 30, or in a possible implementation, a first flow dividing port 32 is provided between the first end and the second end of the distribution arm 30, the first flow dividing port 32 is externally connected with a distribution sub-pipe 33, and the distribution outlet 31 is provided at the outer end of the distribution sub-pipe 33. The axis of the distribution sub-pipe 33 is arranged at a predetermined angle with respect to the axis of the distribution arm 30.

[0098] That is, in this embodiment, in combination with Figure 6 , Figure 9 A bifurcated distribution sub-pipe can be provided on the distribution arm. One end of the distribution sub-pipe is connected to the first flow dividing port on the distribution arm, and then the distribution outlet is located at the other end of the distribution sub-pipe. Through the gathering effect of the distribution sub-pipe on the coolant, the spraying area of the coolant can be expanded, and the area of uniform heat dissipation of the coolant can be improved.

[0099] Furthermore, the axis of the distribution sub-pipe and the axis of the distribution arm are arranged at a predetermined angle. It can be understood in combination with Figure 10At 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.

[0100] 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.

[0101] In one possible implementation, the liquid outlet 31 is inclined relative to the first diversion port 32 toward the second end of the liquid dispensing arm 30; and / or, the liquid outlet 31 is inclined relative to the first diversion port 32 toward the opening of the first accommodating space.

[0102] In this embodiment, on the one hand, combined with Figure 6 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 10 The dispensing tube 33 should be located in the region where the conical surface F is in the negative direction of the X-axis.

[0103] In this embodiment, on the other hand, combined with Figure 2 , 10 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 2 The direction of C2 is the same, which reduces the circulation resistance of the coolant; that is, combined with Figure 10 The dispensing tube 33 should be located in the region where the conical surface F is in the positive direction of the Z-axis.

[0104] In summary, combining the above and Figure 10 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.

[0105] In one possible implementation, the cross section of the distribution cavity 10 is circular along the direction of the central axis 11; and / or, the cross section of the distribution arm 30 is elliptical along the direction of the axis of the distribution arm 30, with the minor axis of the ellipse parallel to the central axis 11 of the distribution cavity 10.

[0106] In this embodiment, the distribution cavity is cylindrical, and then, as shown in Figure 11 , the distribution arm is elliptical, with the minor axis of the ellipse parallel to the central axis of the distribution cavity, so as to reduce the frictional resistance during rotation, and thus to increase the rotation speed of the distribution cavity when rotating at a constant speed.

[0107] Further, the cross section of the distribution sub-pipe can also be elliptical along the direction of the axis of the distribution sub-pipe, with the minor axis of the ellipse parallel to the central axis.

[0108] In one possible implementation, the distribution cavity 10 is provided with a plurality of second distribution openings 12 distributed uniformly along the circumference of the distribution cavity 10 relative to the central axis 11, and the first end of the distribution arm 30 is connected to the second distribution opening 12; the plurality of second distribution openings 12 are distributed in a central symmetry relative to the central axis 11 along the circumference of the distribution cavity 10; the first end of the distribution arm 30 is detachably connected to the second distribution opening 12; and the rotary distributor further comprises a distribution cover 13 for closing the second distribution opening 12 not connected to the distribution arm 30.

[0109] For details, please refer to Figure 12 , that is, a plurality of second distribution openings can be provided along the circumference of the distribution cavity, and then the first end of the distribution arm is inserted or threadedly connected to the second distribution opening, so that the distribution arm is detachably connected, and different numbers of distribution arms can be connected to the distribution cavity according to actual needs, and the second distribution opening not connected to the distribution arm can be closed by the distribution cover; in addition, the plurality of second distribution openings can be distributed in a central symmetry relative to the central axis.

[0110] In combination with the above description of the first distribution opening, it can be seen that the cooling liquid is first distributed from the distribution cavity to different distribution arms through the plurality of second distribution openings; and then, in the same distribution arm, the cooling liquid flows out of the rotary distributor from the distribution arm through the plurality of first distribution openings.
