[0002] Currently, the leveling device for direct-cooling pipeline distributors mainly uses three bolts for leveling, which allows for convenient and quick horizontal adjustment of the equal-volume distributor. This improves the ease of leveling, reduces the difficulty of adjustment, increases the efficiency of adjustment, and thus saves time. However, existing distributors suffer from problems such as imbalance during adjustment, uneven flow distribution, long adjustment time, low efficiency, and inconvenience. To further facilitate convenient and quick horizontal adjustment of the equal-volume distributor, improve the ease of leveling, reduce the difficulty of adjustment, increase the efficiency of adjustment, and thus save time, existing technology has certain drawbacks. For example, once the device is fixed, the height and horizontal position of the target adjustment device cannot be changed. Each time the position of the target adjustment device needs to be changed, the leveling device needs to be disassembled and moved. The leveling method is limited, requires high precision in equipment manufacturing, and if any of the three threaded holes is damaged, the entire internal distributor needs to be replaced.

A mounting plate is connected to the rear side of the base plate, and a lifting seat is connected to the top of the mounting plate. A slide groove is opened on the front side of the lifting seat, and a first slider and a second slider are symmetrically arranged at the upper and lower ends inside the slide groove. A lead screw is connected through the upper side of the first and second sliders. A motor is installed on the top of the lifting seat corresponding to the position of the slide groove. The output end of the motor passes through the lifting seat and is connected to the upper end of the lead screw. A movable seat is connected to the front side of the first slider. A connecting pipe is installed on the inner rear end of the movable seat. A rotating rod is connected to the front end of the connecting pipe. A limit clamp is installed at the front end of the rotating rod. A pressure plate is installed on the front side of the second slider. A pressure rod is connected to the bottom of the pressure plate.

An air supply pipe is connected to the lower side of the air bladder. A telescopic sleeve is connected to the upper end of the front end of the air supply pipe.

[0004] The aforementioned existing technology has the following problems: 1. Existing leveling devices are large in size and heavy in weight, difficult to move, unsuitable for small spaces, and have high space requirements for installation sites.

[0005] 2. Once the existing leveling device is fixed, it is difficult to change the height and horizontal position of the target equipment; if the position needs to be adjusted, the entire heavy base needs to be disassembled and moved, which is cumbersome.

[0006] For example, Chinese utility model patent: Leveling Equal Distribution Tower Device, application publication number: CN223555537U, discloses: including a cylinder, an equal distributor installed on the inner side of the cylinder, and a plurality of adjustment mechanisms arranged on the inner side of the cylinder and distributed sequentially along the circumference of the cylinder; wherein, the adjustment mechanism includes an adjustment support, an adjustment plate, and an adjustment component, the adjustment support is connected to the inner wall of the cylinder, the adjustment plate is connected to the outer periphery of the equal distributor, and the adjustment component is connected to the adjustment support and the adjustment plate respectively and is used to drive the adjustment plate to rise and fall relative to the adjustment support to adjust the horizontal state of the equal distributor.

[0007] The aforementioned existing technology has the following problems: 1. Once the existing device is fixed, the height and horizontal position of the target adjustment equipment cannot be changed. Every time the position of the target adjustment equipment needs to be changed, the leveling device needs to be disassembled and moved.

[0008] 2. The leveling method is limited and requires high precision in equipment processing. If any of the three threaded holes is damaged, the entire internal distributor needs to be replaced. Summary of the Invention

[0020] A fixing spring is provided on the rotating movable bolt.

[0021] A leveling method for a direct-cooling pipeline distributor leveling device, characterized by the following specific steps: Step s1: Periodically iteratively collect historical data on the distance between the dispenser and the battery rack, the distance between the dispenser and the ground, and the historical data on the specification stroke scheme group of the dispenser when the dispenser reaches the average distribution flow condition. Install the leveling device, use the fixed base to fix the clamping device, and level and check the locking of the clamping device. Step s2: According to the specifications of the distributor and the docking position of the distributor with the upper and lower liquid cooling pipes, use the rotating movable bolt to clamp the first conical frame and the second conical frame with the distributor head, and at the same time, press the front ends of the first fixed bending rod and the second fixed bending rod tightly against the distributor head and tighten the nut. Step s3: Connect the lower end of the distributor to the vertical distribution main pipe to receive the refrigerant delivered by the liquid cooling unit, and connect the upper end to the capillary tube on the liquid cooling plate of the battery pack. Step s4: Observe whether the leveling device shifts after the separator is clamped. If it shifts, loosen all bolts to adjust and compensate, then tighten them again to complete the leveling.

[0022] In step s1, the process involves periodic iterations, with the specific steps as follows: Step s1.1: Using simulation to keep the shape of the distributor unchanged, change the pipe diameter and length to obtain the dimensional parameters of the distributor outlet when the liquid distribution is balanced under different given total flow rates; Step s1.2: Based on the dimensional parameters of the liquid dispenser outlet when it achieves balanced distribution, manufacture a test liquid dispenser of the corresponding size; Step s1.3: Set a specific flow rate at the inlet of the dispenser, connect a flow sensor to each outlet of the dispenser, introduce the flow for 1 to 2 minutes, and record the readings of each outlet flow sensor after the flow stabilizes. Step s1.4: When the deviation between the maximum and minimum outlet flow rates of the distributor outlet pipe is less than 4% to 6%, convergence is considered achieved, and the final dimensions are output. Otherwise, the distributor dimensions are optimized, and the simulation cycle is repeated in step 1.

[0023] In step s1, the clamping device is pre-adjusted by using the distance between the dispenser and the battery rack, the distance from the dispenser to the ground, and the specifications of the dispenser when the dispenser reaches the average flow rate condition in the past. Suitable first conical frame, second conical frame, rotating movable component, telescopic movable component, and fixed base frame are selected and the clamping device is installed.

[0024] In step s1, the leveling device levels the fixed base by detecting the levelness of the fixed base with a level on the fixed base; if there is tilt, the clamping position of the clamping fixture is adjusted until the levelness of the fixed base reaches the preset tolerance.

[0025] In step s1, checking the locking condition involves checking whether all component bolts, nuts, rotating movable bolts, and rotating adjusting screws are tightened; whether the elasticity of the fixing spring is intact; and whether the rubber pad is firmly adhered.

[0026] In step s2, the docking position between the distributor and the upper and lower liquid cooling pipelines is adjusted by adjusting the angle of the fixed base and the rotating movable component and the length of the telescopic movable component.

[0027] The advantages of using this invention are: Compared with existing technologies, this invention uses bolts, nuts, slots, and telescopic rods, without any motor or pneumatic system; it is small in size and light in weight, making it suitable for operation in confined spaces such as battery racks; at the same time, this invention does not have components that can move up and down, so that the leveling device cannot move vertically, ensuring that the leveling of the dispensing head can be completed at the same time as the leveling of the device. If the leveling device is slightly offset during the installation of the dispensing device, only minor adjustments are needed to complete the leveling of the dispensing device, making the adjustment method simple.

[0028] Second, compared with the prior art, the tooling base of the present invention is fixed on the battery rack, and the liquid dispenser can still be adjusted in terms of horizontal angle rotation, front and back extension and left and right spacing by loosening the bolts. This multi-degree-of-freedom adjustment does not require moving the base again, which greatly improves the installation efficiency.

[0029] Third, this invention is applicable to various scenarios. When the ground is uneven, the support bracket can be disassembled and replaced with a clamping bracket. When the ground is flat and there is nothing to clamp, the clamping bracket can be disassembled and replaced with a support bracket. By adjusting the screws, it can adapt to different ground conditions, greatly expanding the application range of the equipment.

[0030] Fourth, this invention utilizes historical data on the distance between the distributor and the battery rack, the distance from the distributor to the ground, and the specifications of the distributor when the distributor reaches the average flow rate condition. Based on this data, the corresponding length of the adjustment rod or the height of the bracket can be directly selected, which greatly shortens the on-site debugging time and ensures the consistency of installation quality for different batches and different personnel.

[0031] V. The present invention provides protrusions on the first conical frame and the second conical frame to ensure that the first fixed bending rod and the second fixed bending rod will not shift downward after being fixed, and to ensure the accuracy of the first fixed bending rod and the second fixed bending rod when they are in close contact with the dispenser.

[0043] This invention provides a detachable leveling device and method for a direct-cooling distributor, mainly to solve the problem of unbalanced installation and tilting of the refrigerant distributor head in existing direct-cooling systems. Specifically, it refers to: assisting in the installation and leveling of the distributor head; and enabling free adjustment of the installation position.

[0044] like Figure 1 and Figure 2 As shown, the entire tooling of this invention mainly comprises a fixed base frame 1, a movable screw 24, a fixed pressure head 25, a rubber pad 20, a bolt 38, a nut 39, a rotating movable component 2, a fixed pin 34, a telescopic movable component 3, a first conical frame 9, a second conical frame 10, a fixed spring 40, a fixed spring 40 washer, a first fixed bent rod 12, and a second fixed bent rod 13. The movable screw 24 is screwed into the fixed base frame 1 through the through hole 8 of the straight plate 18 at one end. Then, one end of the movable screw 24 is connected to the fixed pressure head 25. A rubber pad 20 is fixed on the end face of the other straight plate 18, and the rubber pad 20 on the movable screw 24 is fixed on the end face of the fixed pressure head 25. The two rubber pads 20 are fixedly placed facing each other.

[0045] When using the fixed base frame, place the vertical rod of the battery rack between the two straight plates 18 at one end of the fixed base frame 1, observe the level of the level instrument 5, and ensure that the maximum height difference of the tilt within the leveling range is less than or equal to 2mm to 5mm; then, when the movable screw 24 is rotated clockwise, the fixed pressure head 25 will gradually press the vertical rod of the battery rack, and the two rubber pads 20 will press against the two end faces of the vertical rod of the battery rack to increase the friction, so that the fixture is fixed on the vertical rod of the battery rack.

[0046] like Figure 4 As shown, bolts 38 are used to connect the first connector 16 on the fixed base frame 1 to the third connector 31 of the rotating movable component 2.

[0047] like Figure 5 and Figure 6 As shown, the end face sawtooth groove 23 structure at the contact point between the fixed base frame 1 and the rotating movable component 2 is shown respectively. When the fixed base frame 1 and the rotating movable component 2 are connected, the pattern of the sawtooth groove 23 and the pattern of the sawtooth 32 are engaged one-to-one. In addition, the through hole 8 at the connection port between the fixed base frame 1 and the rotating movable component 2 is designed as a square hole 41, and the bolt 38 is designed with a directional block to prevent the bolt 38 from rotating.

[0048] When the rotating movable component 2 is in use, rotating the bolt 38 counterclockwise gradually reduces the contact pressure between the serrations 32 on the outer periphery of the through hole 8 on the first connector 16 of the fixed base frame 1 and the serration groove 23 on the outer periphery of the through hole 8 on the third connector 31 of the rotating movable component 2. At this time, the rotating movable component 2 can be rotated horizontally to a suitable angle. Then, rotating the nut 39 clockwise gradually increases the contact pressure between the serrations 32 and the serration groove 23 until the rotating movable component 2 is finally completely locked and fixed. The part where the rotating movable component 2 connects to the third connector 31 has two slots 6 on the top and bottom, and multiple through holes 8 are opened through the slot plates of the two slots 6.

[0049] like Figure 7 As shown, the upper and lower long plates 7 of the telescopic movable component 3 are provided with opposing through holes 8; as Figure 8 As shown, during installation, the long plate 7 of the telescopic movable component 3 is directly inserted into the slot 6 of the rotating movable component 2; when in use, the telescopic movable component 3 is adjusted to a suitable position in the horizontal direction by extending and retracting it in the slot 6 through the long plate 7, so that the through hole 8 on the long plate 7 of the telescopic movable component 3 is aligned with the corresponding through hole 8 on the rotating movable component 2, and then the fixing pin 34 is inserted to fix the movement of the telescopic movable component 3.

[0050] like Figure 9 As shown, the fifth connector 35 of the first conical frame 9 and the sixth connector 36 of the second conical frame 10 are fixed to the fourth connector 33 of the telescopic movable component 3 by bolts 38. At the same time, the arms of the first conical frame 9 and the second conical frame 10 are respectively provided with two through holes 8, which are fixed by rotating movable bolts 11 passing through the through holes 8. A fixing spring 40 is provided on the rotating movable bolt 11, and a fixing spring 40 washer is provided on the end face of the fixing spring 40. The end faces of the two conical frames 4 are provided with through holes 8, which pass through the first fixing bent rod 12 and the second fixing bent rod 13 respectively, and are respectively fixed by nuts 39.

[0051] One end of the first conical frame 9 and the second conical frame 10 is designed with a conical groove 46 for placing the dispensing head, restricting the dispensing head from moving horizontally, downward, and rotating in any direction, and adjusting the size of the dispensing head that can be placed between the first conical frame 9 and the second conical frame 10 by moving closer or further apart. This operation is achieved by the tensioning and contraction of the fixed spring 40 and the rotation of the movable bolt 11.

[0052] When using the separator head fixing structure, first place the separator head in the conical groove 46 of the first conical frame 9 and the second conical frame 10, and then install the first fixing rod 12 and the second fixing rod 13 in sequence. The two rods are designed with bosses 37 for locking. The front ends of the two rods are attached to the upper part of the separator head. While tightening the nut 39 clockwise, the axial up and down movement of the separator head is restricted.

[0053] like Figure 10 As shown, tighten the nut 39 clockwise, the first fixed bent rod 12 and the second fixed bent rod 13 move closer to each other, the fixed spring 40 is compressed, and the liquid separator head is fully pressed, thus achieving clamping and fixing.

[0054] This invention does not have components that can move up and down; it can only be adjusted left and right, so that the leveling device cannot move vertically. When the leveling device is clamped, the dispensing head will automatically maintain the required leveling state, ensuring that the leveling of the device is completed at the same time as the leveling of the dispensing head. If the leveling device is slightly offset during the clamping and installation of the dispensing device, only a small adjustment is needed to complete the leveling of the dispensing device. The adjustment method is simple.

[0055] Example 2 The supporting bracket 15 includes a fixed bracket 26 and a bracket base 27; the fixed bracket 26 and the bracket base 27 are connected by a rotating adjusting screw 28, and the height of the fixed bracket 26 is adjusted by rotating the adjusting screw 28; the fixed bracket 26 includes a connecting rod 29 and a second connecting head 30, the connecting rod 29 and the second connecting head 30 are connected as a whole, a level 5 is provided on the outer side of the second connecting head 30, and the third connecting plate 42 and the fourth connecting plate 43 on the second connecting head 30 are provided with opposing through holes 8; the fixed bracket 26 is fixedly connected to the telescopic movable component 3 by bolts 38 passing through the through holes 8.

[0056] like Figure 3 and 11 As shown, optionally, if the site is flat or clamping conditions are not available in the actual project, the clamping fixing bracket 14 can be disassembled and replaced with the support fixing bracket 15. Align the through hole 8 on the second connector 30 of the support fixing bracket 15 with the through hole 8 on the third connector 31 of the telescopic movable component 3, and then insert the fixing pin 34 to fix it. A level 5 is provided on the outer side of the second connector 30. The levelness of the support fixing bracket 15 can be adjusted by observing the level 5. The bracket base 27 at the lower end of the support fixing bracket 15 includes, but is not limited to, tripods, discs, etc. The height of the bracket can be adjusted by rotating the adjusting screw 28. When there are no clamping conditions on site or the site is flat, the position of the leveling device can be adjusted by moving the support fixing bracket 15. The support fixing bracket 15 is used for installation. ①Based on historical records of the distance between the dispenser and the battery rack, the distance between the dispenser and the ground, and the specifications of the dispenser when the dispenser reaches the average distribution flow condition, determine the height of the clamping device from the ground and select a suitable height-adjustable bracket. ② Disassemble the original fixed base frame assembly and connect the support fixed bracket to the telescopic movable component through the fixing pin; ③ Place the support base and rotate the adjusting screw to adjust the dispenser to the appropriate height from the ground.

[0057] Example 3 A leveling method for a direct-cooling pipeline distributor leveling device, the specific steps of which are as follows: Step s1: Use periodic iteration to change the thermal load conditions and liquid cooling pipeline layout parameters, while adjusting the spatial position of the distributor in front of the battery rack. Collect historical data on the distance between the distributor and the battery rack, the distance from the distributor to the ground, and the distributor's specification stroke scheme group when the distributor reaches the average distribution flow condition. Install the leveling device, use the fixed base to fix the clamping device, and level and check the locking of the clamping device. Step s2: According to the specifications of the distributor and the docking position of the distributor with the upper and lower liquid cooling pipes, use the rotating movable bolt 11 to clamp the first conical frame 9 and the second conical frame 10 to clamp the distributor head of the distributor. At the same time, the front ends of the first fixed bending rod 12 and the second fixed bending rod 13 are pressed tightly against the distributor head, and the nut 39 is tightened. Step s3: Connect the lower end of the distributor to the vertical distribution main pipe to receive the refrigerant delivered by the liquid cooling unit, and connect the upper end to the capillary tube on the liquid cooling plate of the battery pack. Step s4: Observe whether the leveling device shifts after the separator is clamped. If it shifts, loosen all bolts 38 to adjust and compensate, then tighten them again to complete the leveling.

[0058] In step s1, the process involves periodic iterations, with the specific steps as follows: Step s1.1: Using simulation to keep the shape of the distributor unchanged, change the pipe diameter and length to obtain the dimensional parameters of the distributor outlet when the liquid distribution is balanced under different given total flow rates; Step s1.2: Based on the dimensional parameters of the liquid dispenser outlet when it achieves balanced distribution, manufacture a test liquid dispenser of the corresponding size; Step s1.3: Set a specific flow rate at the inlet of the dispenser, connect a flow sensor to each outlet of the dispenser, introduce the flow for 1 to 2 minutes, and record the readings of each outlet flow sensor after the flow stabilizes. Step s1.4: When the deviation between the maximum and minimum outlet flow rates in the distributor outlet pipe in the test results is less than 4%~6%, it is considered converged, and the final size is output. Otherwise, optimize the distributor size, substitute it back into the first step for simulation loop, and output the final distributor size.

[0059] In step s1, the clamping device is pre-adjusted by using the distance between the dispenser and the battery rack, the distance between the dispenser and the ground, and the specifications of the dispenser when the dispenser reaches the average flow rate condition in the past. The appropriate first conical frame 9, second conical frame 10, rotating movable component 2, telescopic movable component 3 and fixed base frame 1 are selected and the clamping device is installed.

[0060] In step s1, the leveling device levels the fixed base frame 1 by detecting the levelness of the fixed base frame 1 using the level 5 on the fixed base frame 1; if there is tilt, the clamping position of the clamping fixture is adjusted until the levelness of the fixed base frame 1 reaches the preset tolerance.

[0061] In step s1, checking the locking condition involves checking whether all component bolts 38, nuts 39, rotating movable bolts 11, and rotating adjusting screws 28 are locked; whether the elasticity of the fixing spring 40 is intact; and whether the rubber pad 20 is firmly adhered.

[0062] In step s2, the docking position of the distributor with the upper and lower liquid cooling pipelines is adjusted by adjusting the angle of the fixed base 1 and the rotating movable component 2 and the length of the telescopic movable component 3.

[0063] The specific steps for using it are as follows: Step 1: Simulate the condition when the distributor reaches the average flow distribution using a periodic iterative method. Record relevant data such as heat load conditions, distributor specifications, liquid cooling pipeline parameters, distance between the distributor and the battery rack, and distance from the distributor to the ground. Replace distributors of different specifications and adjust their spatial positions, recording the above-mentioned relevant data when the flow is evenly distributed for different specifications of distributors. Sequentially allocate the distance between the distributor and the battery rack, the distance from the distributor to the ground, and the historical data of the corresponding distributor specifications forming a scheme group. Based on the size parameters of different specifications of distributors, fabricate the first conical frame 9 and the second conical frame 10 of corresponding specifications (e.g., size, shape, etc.). Based on the distance L between the distributor and the battery rack, fabricate the rotating movable component 2 and the telescopic movable component 3 with corresponding adjustable lengths. Based on the distance from the distributor to the ground, fabricate the support with corresponding adjustable height. Determine the distance between the distributor and the battery rack. Replace and install the rotating movable component 2 and telescopic movable component 3 of the conical frame 4 to meet the reasonable length adjustment range; perform adaptive pre-adjustment of the conical frame 4, and select a reasonable scheme group according to the actual project conditions; check each bolt 38, nut 39, screw, rotating movable bolt 11 and rotating adjusting screw 28 to confirm that there is no stripping or jamming; check that the fixing spring 40 is elastic and has no plastic deformation; check that the rubber pad 20 is firmly adhered and has no detachment or damage; adjust the clamping height from the ground according to the actual situation of the liquid separator, and adjust the fixing height; after the conical frame 4 is fixed, the level 5 can be placed on the upper plane of the fixed base 1 to check the levelness of the fixed base 1. If there is tilt, slightly loosen the movable screw 24, fine-tune the tooling clamping position until the levelness of the fixed base 1 reaches the preset tolerance, and tighten the movable screw 24 again to complete the secondary locking.

[0064] The periodic iteration includes: 1. Simulation analysis: Using simulation, with the shape of the distributor fixed, the pipe diameter and length are changed to obtain the dimensional parameters of the distributor outlet when the liquid distribution is balanced under different given total flow rates; 2. Prototype fabrication: Based on the above dimensional parameters, a test distributor of corresponding dimensions is fabricated; 3. Testing and verification: A specific flow rate is given at the inlet of the distributor, and a flow sensor is connected to each outlet of the distributor. The flow rate is introduced for 1-2 minutes, and after stabilization, the readings of each outlet sensor are recorded; 4. Iterative optimization: When the deviation between the maximum and minimum outlet flow rates in the outlet pipe in the above test results is less than 4%-6%, convergence is considered, and the final dimensions are output; otherwise, the distributor dimensions are optimized, and the simulation cycle is repeated in step 1.

[0065] Step 2: Place the dispensing head into the conical groove 46 on the first conical frame 9 and the second conical frame 10. The conical groove 46 restricts the dispensing head's upward and downward movement in the horizontal direction and its rotation in any direction. Rotate the bolt 38 counterclockwise to release the engagement and locking between the fixed base frame 1 and the serrated groove 23 on the end face of the rotating movable component 2. Rotate the movable component 2 horizontally, and based on the designed number of teeth in the serrated groove 23 and considering the docking position of the dispensing device with the upper and lower liquid cooling pipes, quantitatively adjust the dispensing head to a suitable installation angle in the horizontal left and right directions. Then rotate the movable nut 39 clockwise to fully engage the serrated groove 23 and lock the rotation angle. Move the telescopic movable component 3 back and forth, and adjust the telescopic movable component 3 to a suitable position according to the distance L between the dispensing device and the battery rack. Align the through hole 8 on the long plate 7 of the telescopic movable component 3 with the corresponding through hole 8 on the rotating movable assembly, insert the fixing pin 34 to fix the axial movement of the telescopic movable component 3, and gently pull to confirm that there is no movement; install the first fixing rod 12 and the second fixing rod 13 in sequence, with the long side of the rod attached to the upper part of the distributor head, and the boss 37 to achieve locking; tighten the nut 39 under the second fixing rod 13 clockwise to restrict the axial up and down movement of the distributor head; tighten the rotating movable bolt 11 clockwise, the first fixing rod 12 and the second fixing rod 13 move closer to each other, and the fixing spring 40 is compressed; the first conical frame 9 and the second conical frame 10 clamp the distributor head simultaneously to achieve leveling and fixing of the distributor head.

[0066] Step 3: Connect the lower end of the distributor to the vertical distribution manifold to receive the refrigerant delivered by the liquid cooling unit, and connect the upper end to the capillary tube to allow the refrigerant to flow into the liquid cooling plates of different battery packs.

[0067] Step 4: Gently shake the distributor head to confirm that the fixture is securely clamped and that there is no deformation or damage to the pipe connection end face. If the leveling device is slightly offset during the clamping and installation process, use the level 5 to measure whether the distributor is level again. If there is a slight tilt, slightly loosen the corresponding rotating nut 39 for a small compensation adjustment, and immediately tighten it again after adjustment.

[0068] Disassemble in reverse order of installation: ① First, loosen the rotating bolt to reset the fixing spring, and then loosen the clamping of the conical frame on the dispensing head; ② Loosen the nut and remove the second fixed bend rod; pull out the fixing pin, loosen the bolt, and release the locking of the telescopic and rotating movable components; ③ Finally, rotate the movable screw counterclockwise to remove the tooling from the vertical rod of the battery rack.
