Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, specifically a combined liquid cooler applied to multi-cell testing. Background Technology

[0002] Battery cells generate a lot of heat, so they must be equipped with an efficient and precise thermal management system to maintain the cells at the set temperature conditions and ensure the accuracy, consistency and safety of test data.

[0003] In existing liquid chillers, the cooling medium circulating inside inevitably oxidizes and decomposes over long periods due to contact with metal components such as pipes, joints, and pumps. It may also combine with trace impurities introduced by the battery cell testing environment, forming sludge-like contaminants. Simultaneously, mechanical impurities such as metal shavings and sealing material particles may gradually accumulate within the system. If these oil stains and impurities are not cleaned promptly, they will adhere to the inner walls of the pipes, especially in the flow channels of critical components such as plate heat exchangers, precision valves, and filters, leading to serious problems: First, a significant reduction in heat exchange efficiency decreases the temperature control capability of the liquid chiller, directly affecting the temperature stability of battery cell testing; second, increased circulation resistance leads to increased pump load, higher energy consumption, and even malfunctions; third, it may clog precision flow channels or damage sensors, resulting in reduced system reliability, dramatically increased maintenance costs, and prolonged downtime of the entire testing system due to cleaning and maintenance.

[0004] In existing technologies, the conventional maintenance method involves installing a simple filter at the inlet of the liquid chiller and periodically stopping the machine for manual cleaning or replacement of the cooling medium. This method has limited filtration accuracy and cannot effectively separate viscous oily contaminants.

[0005] Therefore, there is a need for a liquid chiller that can improve the cleaning effect of the pipes and, after thoroughly cleaning the impurities in the liquid cooling pipes, can improve the heat exchange efficiency and ensure that the liquid chiller has sufficient temperature control capabilities. This is an urgent technical need and has significant market value. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Figures 1-6 As shown, this invention provides a technical solution for a combined liquid chiller applied to multi-cell testing. The combined liquid chiller includes a cabinet 1, a testing unit 2 housed within the cabinet 1, a water pump 3 located at the bottom of the cabinet 2, the water pump 3 connected to a liquid cooling unit 4, the liquid cooling unit 4 connected to a cooling pipe 5, and a cleaning unit 6 housed within the cooling pipe 5. The testing unit 2 includes a testing platform 21, a baffle 22 mounted on the testing platform 21, heat insulation plates 2201 mounted on both sides of the baffle 22, a testing element 23 mounted on the top of the testing platform 21, and a control center located on one side of the testing platform 21. 24; During the cell testing process, multiple cells to be tested are placed into the areas divided by the baffle 22. Then, the control center 24 performs a series of tests on the cells. The testing device 23 can test all cells at any time. During the testing process, in addition to the cooling pipe 5 at the bottom of the testing platform 21 for heat dissipation, exhaust fans 14 and many evenly distributed heat sinks 13 are also installed on the cabinet to ensure that the cells always operate under the set temperature conditions during the testing process, ensuring the accuracy, consistency and safety of the test data.

[0021] The liquid cooling circuit inside the liquid chiller consists of the liquid cooling unit 4 and the cooling pipe 5. The pressure stabilizing tank on the water pump 3 provides a sufficient and stable power source for the circulation of the liquid cooling circuit, ensuring stable cooling. The flow rate in the pipe can be adjusted by adjusting the ball valve 4303, thereby adjusting the cooling speed of the battery cell. The check valve 4202 on the return pipe 42 can prevent the backflow of coolant and affect the normal circulation of coolant. A filter 32 is installed at the connection between the output end of the water pump 3 and the liquid cooling unit 4, which can initially filter out most of the impurities in the water tank 12, alleviating the accumulation of impurities in the liquid cooling unit 4 and the cooling pipe 5. During long-term circulation, the cooling medium in the liquid cooling circuit will inevitably oxidize and decompose gradually due to contact with metal parts such as pipes, joints, and pump body, forming sludge-like contaminants. If not cleaned in time, it will affect the cooling efficiency of the liquid chiller.

[0022] When pipe cleaning is required, the cleaning unit 6 can be placed into the liquid cooling circuit. The minimum diameter of the cleaning unit 6 must be smaller than the smallest diameter section of the pipe in the liquid cooling circuit, so that the cleaning unit 6 can be smoothly inserted, ensuring that the outer cleaning ring 6703 is tightly against the inner wall of the pipe. Then, by starting the motor 64, the paddle 6401 is driven to rotate, thus providing forward power for the cleaning unit 6. At the same time, a small motor is also installed in the drive wheel 6501 to assist the movement of the cleaning unit 6. The cleaning ring 6703 scrapes off the oil stains adhering to the inner wall, and the scraped oil stains flow into the collection tank 6 along the cleaning ring 6703. Within 103, the oil stains are collected. During the movement of the cleaning unit 6, the arc-shaped plate 6303 protects the drive component 61, preventing larger impurities in the pipe from damaging it. When the pipe diameter changes, the camera 6302 at the front of the cleaning unit 6 measures the pipe diameter and controls the operation of the regulating motor 62. Both ends of the regulating motor 62 rotate simultaneously. First, the regulating motor 62 drives the main lead screw 63 to rotate, which in turn moves the sliding seat 67 on the main lead screw 63. During the movement of the sliding seat 67, the first airbag 6702 is compressed. Airbag 6702 is connected to the second airbag 6704. Therefore, the gas in the first airbag 6702 is forced into the second airbag 6704, increasing its volume. This causes the cleaning ring 6703 to expand outward, allowing it to continue to scrape away oil stains while adhering tightly to the inner wall of the pipe. Meanwhile, the movement of the sliding seat 67 drives the connecting rod 6701 to rotate, causing the arc-shaped plate surrounding the main lead screw 63 to expand outward, continuing to protect the components on the drive unit 61. On the other hand, the adjusting motor 62 drives the adjusting gear 6201 at the other end to rotate. Because the adjusting gear 6201 and the gear on the auxiliary lead screw 66... When 6601 engages, the auxiliary lead screw 66 rotates accordingly, causing the telescopic rod 6502 on the auxiliary lead screw 66 to move along the auxiliary lead screw 66, driving the folding rod 65 to rotate outward. Ultimately, the drive wheel 6501 also adheres to the inner wall of the pipe, maintaining the stability of the cleaning unit 6's movement. Furthermore, by setting the telescopic rod 6502, the drive wheel 6501 can have a certain amount of extension and retraction, allowing the cleaning unit 6 to pass through some bends, further improving the cleaning capacity of the device. The improved cleaning capacity of the liquid chiller pipe can reduce losses in the cooling cycle, improve heat exchange efficiency, and thus enhance the temperature control capability of the liquid chiller.

[0023] The cleaning unit 6 includes a drive unit 61, with a accommodating chamber 6101 in the middle of the drive unit 61. Both ends of the accommodating chamber are sealed by end caps 6102. An adjusting motor 62 is installed inside the accommodating chamber 6101. One end of the adjusting motor 62 is connected to the main lead screw 63, and the other end of the adjusting motor 62 is provided with an adjusting gear 6201. The drive chamber 61 is provided with a collection groove 6103 and an adjusting chamber 6104 in the inner ring. A motor 64 is provided near the adjusting gear 6201, and the output end of the motor 64 is connected to a blade 6401.

[0024] The drive component 61 has evenly spaced storage slots 6105 on its outer side. A folding rod 65 is rotatably connected inside the storage slot 6105. A drive wheel 6501 is provided at the end of the folding rod 65. A secondary lead screw 66 is provided at the bottom of the storage slot 6105. The folding rod 65 and the secondary lead screw 66 are connected by a telescopic rod 6502. A spring 6503 is sleeved on the telescopic rod 6502. A gear 6601 is provided at one end of the secondary lead screw 66. The gear 6601 is located inside the adjustment chamber 6104.

[0025] A main end cap 6301 is provided at the end of the main lead screw 63. A camera 6302 is installed on the main end cap 6301. Several arc-shaped plates 6303 are rotatably connected to the outside of the main end cap 6301. A sliding seat 64 is sleeved on the main lead screw 63. Several connecting rods 6401 are rotatably connected to the outside of the sliding seat 64. The connecting rods 6401 are connected to the arc-shaped plates 6303. A first airbag 6402 is provided at the bottom of the sliding seat 64. A cleaning ring 6403 is provided around the outside of the drive chamber 61. A second airbag 6404 is provided inside the cleaning ring 6403. The first airbag 6402 and the second airbag 6404 are connected.

[0026] The liquid cooling unit 4 includes an inlet pipe 41 and a return pipe 42. The inlet pipe 41 includes a transition pipe 43, which is provided with a first inlet 4301 and a second inlet 4302. The second inlet 4302 is provided with a regulating ball valve 4303. The return pipe 42 is provided with a return port 4201 and a check valve 4202.

[0027] The cooling pipe 5 is a serpentine pipe. One end of the cooling pipe 5 is connected to the second liquid inlet 4302, and the other end of the cooling pipe 5 is connected to the liquid return port 4201. The cooling pipe 5 is located at the bottom of the test platform 21. The serpentine pipe can increase the contact area between the cooling pipe 5 and the bottom of the test platform 21, thereby improving the cooling efficiency of the battery cell.

[0028] The bottom of the cabinet 1 is equipped with casters 11, the inside of the cabinet 1 is equipped with a water tank 12, the outside of the cabinet 1 is equipped with radiators 13, and the rear of the cabinet 1 is equipped with an exhaust fan 14.

[0029] The cabinet 1 is also equipped with a water collection tank 7, which is located at the bottom of the liquid cooling unit 4. A leakage sensor 71 is installed in the water collection tank 7. When a leak occurs in the liquid cooling circuit, the leaked liquid will fall to the bottom of the cabinet 1. Since the water collection tank 7 is the lowest point in the cabinet, the leaked liquid will eventually collect in the water collection tank 7. The leakage sensor 71 installed in the water collection tank 7 can detect the composition of the liquid in the water collection tank 7. When the presence of coolant is detected in the liquid, an alarm will be issued in time to remind the staff to stop the machine for maintenance.

[0030] A pressure stabilizing tank 31 is installed on the top of the water pump 3. The input end of the water pump 3 is connected to the water tank 12, and the output end of the water pump 3 is connected to the first liquid inlet 4301. A filter 32 is installed at the output end of the water pump 3. The pressure stabilizing tank 31 on the water pump 3 can provide a sufficient and stable power source for the circulation of the liquid cooling circuit, ensuring stable cooling. The flow rate in the pipeline can be adjusted by adjusting the ball valve 4303, thereby adjusting the cooling speed of the battery cell. The check valve 4202 installed on the return pipeline 42 can prevent the backflow of coolant and affect the normal circulation of coolant. A filter 32 is installed at the connection between the output end of the water pump 3 and the liquid cooling unit 4, which can initially filter out most of the impurities in the water tank 12 and alleviate the accumulation of impurities in the liquid cooling unit 4 and the cooling pipe 5.

[0031] Working principle of the invention: During the cell testing process, multiple cells to be tested are placed into different areas divided by baffle 22. Then, the control center 24 performs a series of tests on the cells. The testing device 23 can test all cells at any time. During the testing process, in addition to the cooling pipe 5 at the bottom of the testing platform 21 for heat dissipation, exhaust fans 14 and many evenly distributed heat sinks 13 are also installed on the cabinet to ensure that the cells always operate under the set temperature conditions during the testing process, ensuring the accuracy, consistency and safety of the test data.

[0032] The liquid cooling circuit inside the liquid chiller consists of the liquid cooling unit 4 and the cooling pipe 5. The pressure stabilizing tank 31 installed on the water pump 3 provides a sufficient and stable power source for the circulation of the liquid cooling circuit, ensuring stable cooling. The flow rate in the pipe can be adjusted by adjusting the ball valve 4303, thereby adjusting the cooling speed of the battery cell. The check valve 4202 installed on the return pipe 42 can prevent the backflow of coolant and affect the normal circulation of coolant. A filter 32 is installed at the connection between the output end of the water pump 3 and the liquid cooling unit 4, which can initially filter out most of the impurities in the water tank 12, alleviating the accumulation of impurities in the liquid cooling unit 4 and the cooling pipe 5. During long-term circulation, the cooling medium in the liquid cooling circuit will inevitably oxidize and decompose gradually due to contact with metal parts such as pipes, joints, and pump body, forming sludge-like contaminants. If not cleaned in time, it will affect the cooling efficiency of the liquid chiller.

[0033] When pipe cleaning is required, the cleaning unit 6 can be placed into the liquid cooling circuit. The minimum diameter of the cleaning unit 6 must be smaller than the smallest diameter part of the pipe in the liquid cooling circuit, so that the cleaning unit 6 can be smoothly inserted, ensuring that the outer cleaning ring 6703 is tightly against the inner wall of the pipe. Then, by starting the motor 64, the paddle 6401 is driven to rotate, thereby providing forward power for the cleaning unit 6. At the same time, a small motor is also installed in the drive wheel 6501 to assist the movement of the cleaning unit 6. The cleaning ring 6703 scrapes off the oil stains adhering to the inner wall, and the scraped oil stains follow the cleaning... The oil slick flows into the collection tank 6103 through the ring 6703, collecting the oil. During the movement of the cleaning unit 6, the arc-shaped plate 6303 protects the drive component 61, preventing damage from larger impurities in the pipe. When the pipe diameter changes, the camera 6302 at the front of the cleaning unit 6 measures the pipe diameter and controls the operation of the regulating motor 62. Both ends of the regulating motor 62 rotate simultaneously. First, the regulating motor 62 drives the main lead screw 63 to rotate, which in turn moves the sliding seat 67 on the main lead screw 63. During the movement of 67, the first airbag 6702 is compressed. Since the first airbag 6702 is connected to the second airbag 6704, the gas inside the first airbag 6702 is forced into the second airbag 6704, causing it to expand in volume. This causes the cleaning ring 6703 to expand outward, allowing it to continue to scrape away oil stains while adhering tightly to the inner wall of the pipe. The movement of the sliding seat 67 also drives the connecting rod 6701 connected to it to rotate, causing the arc-shaped plate surrounding the main lead screw 63 to expand outward, continuing to protect the components on the drive unit 61. On the other hand, the adjusting motor 62 also drives... The adjusting gear 6201 at the other end rotates. Since the adjusting gear 6201 meshes with the gear 6601 on the auxiliary lead screw 66, the auxiliary lead screw 66 also rotates. This causes the telescopic rod 6502 on the auxiliary lead screw 66 to move along the auxiliary lead screw 66, driving the folding rod 65 to rotate outward. Ultimately, the drive wheel 6501 also adheres to the inner wall of the pipe, maintaining the stability of the cleaning unit 6's movement. Furthermore, by setting the telescopic rod 6502, the drive wheel 6501 can have a certain amount of extension and retraction, allowing the cleaning unit 6 to pass through some bends, further improving the cleaning capacity of the device.

[0034] The test station 21 is divided into multiple areas by the baffle 22. Each area can hold a battery cell, and the test piece 23 tests all the battery cells in all areas. During the test, the cooling pipe 5 at the bottom of the test station 21 dissipates heat from the battery cells in time, maintaining the battery cells at the set temperature conditions and ensuring the accuracy of the test data.

[0035] The liquid cooling unit 4 and the cooling pipe 5 form a liquid cooling circuit. The cooling efficiency of the liquid chiller is ensured by the cooperation of various valves. At the same time, the leakage sensor 71 set at the bottom of the liquid cooling unit 4 can detect the sealing of the liquid cooling circuit at all times to ensure the normal operation of the liquid chiller.

[0036] The cleaning unit 6 installed in the liquid cooling circuit can remove impurities and oil stains from the inner wall of the pipe. Since the pipe diameters in the liquid cooling unit 4 are not uniform, the cleaning unit 6 can adaptively adjust according to the pipe diameter to ensure that the cleaning ring 6703 is always in close contact with the inner wall of the pipe, and thoroughly remove the oil stains in the liquid cooling pipeline.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
