Description

Technical Field

[0001] The invention relates to the technical field of testing equipment, in particular to a flow-water type liquid heating module testing platform. Background Art

[0002] A liquid heater is a device that precisely heats liquids to a specific temperature and is widely used in the chemical, food, and scientific research industries. Liquid flows in through an inlet connector, where an internal heating wire converts electrical energy into heat, heating the liquid before discharging it through an outlet connector. A liquid cooler, on the other hand, allows high-temperature liquid to flow into a radiator pipe. As it passes through the fins, air cools the liquid, removing heat and cooling it. These coolers are commonly used in industrial cooling applications.

[0003] During testing, after the liquid heater is connected to the flow-through test platform, the platform's water pump injects low-temperature liquid. The heated liquid then flows back, which is monitored by temperature sensors to determine performance. During testing of the liquid cooler, the platform's water pump injects high-temperature liquid, and the cooled, low-temperature liquid then flows back, which is monitored for temperature to determine performance. However, existing testing technology has drawbacks. The liquid heater and liquid cooler each utilize independent test platforms, resulting in poor versatility. The liquid heated by the liquid heater and the liquid tested by the liquid cooler are not fully utilized, resulting in wasted resources, increased costs and space usage, and hindering large-scale integrated testing.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figures 1 to 11 As shown, the present invention includes the following embodiments:

[0033] Example 1: A flow-type liquid heating module test platform, comprising a test box 1 and a water tank 2 and a water pump 3 inside the test box 1; the water tank 2 is placed horizontally and fixedly connected directly below the water pump 3; the water tank 2 is slidably and sealedly connected to a piston plate 21 inside; the piston plate 21 divides the water tank 2 into a hot chamber 22 and a cold chamber 23; a first joint 11 and a second joint 12 are provided on one side of the test box 1; the first joint 11 is connected to the hot chamber 22 through a hot water pipe 4; the second joint 12 is connected to the cold chamber 23 through a cold water pipe 5; the hot water pipe 4 And the temperature sensor 41 is connected in series on the cold water pipe 5; the cold water pipe 5 is connected in series and connected to the inner side of the outer ring shell 6; the inner side of the outer ring shell 6 is provided with an inner ring shell 7; the water pump 3 is fixedly connected to the inner side of the inner ring shell 7, and the two joints of the water pump 3 are symmetrically connected to the outer side of the inner ring shell 7; the rotating ring 8 is rotatably sealed and connected between the inner side of the outer ring shell 6 and the outer side of the inner ring shell 7 near the two ports; the two S-shaped blocks 9 are symmetrically fixedly connected to the common center of the two rotating rings 8; the two S-shaped blocks 9 separate the space between the two rotating rings 8 into two independent conversion chambers 91.

[0034] After pushing the test box 1 to the liquid heater test area using the universal wheels at the bottom, connect the liquid inlet joint of the liquid heater to the second joint 12, connect the liquid outlet joint of the liquid heater to the first joint 11, and rotate one of the swivels 8. The rotation of one of the swivels 8 will drive the two S-shaped blocks 9 and the other swivel 8 to rotate. For the sake of convenience, the pipe opening connecting the cold water pipe 5 to the inner wall of the outer ring shell 6 is called the outer opening, and the pipe openings connecting the two symmetrical joints of the water pump 3 to the outer wall of the inner ring shell 7 are called the inner opening. One side of the test box 1 with the first joint 11 and the second joint 12 is in the main viewing direction. In the main viewing direction, the water pump 3 is horizontally connected in series to the cold water pipe 5. In the main viewing direction, (such as Figure 3 and Figure 8 ) The inner and outer ports on the cold water pipe 5 are, from left to right, the first outer port, the first inner port, the second inner port, and the second outer port. When the two S-shaped blocks 9 are moved away from between the corresponding outer and inner ports, the first outer port is directly connected to the first inner port, and the second inner port is directly connected to the second outer port.

[0035] In the main viewing direction, the right port of the water pump 3 sucks in liquid and the left port discharges liquid. When the water pump 3 is working, the low-temperature liquid in the cold chamber 23 at the right position enters the second outer port along the cold water pipe 5 under the action of the negative pressure of the water pump 3 and passes through the second inner port to enter the right port of the water pump 3. The water pump 3 will discharge the low-temperature liquid along the left port into the first inner port and into the second outer port. The low-temperature liquid will continue to pass through the temperature sensor 41 on the cold water pipe 5 and the second joint 12 to enter the liquid inlet joint of the liquid heater. After the liquid heater is heated, the low-temperature liquid is discharged along the liquid outlet joint of the liquid heater. The high-temperature liquid discharged from the liquid outlet joint of the liquid heater will enter the hot water pipe 4 along the first joint 11. The temperature sensor 4 on the hot water pipe 4 1. The temperature of the high-temperature liquid is monitored. The performance parameters of the liquid heater are obtained based on the measured temperature and liquid flow time, and compared with the standard values ​​to determine whether the liquid heater meets the qualification requirements. The high-temperature liquid entering the hot water pipe 4 will flow into the hot chamber 22 for storage. During the flow of the liquid in the cold chamber 23, a negative pressure will be formed in the space inside the cold chamber 23, causing the piston plate 21 in the water tank 2 to move right. The rightward movement of the piston plate 21 will increase the space in the hot chamber 22 to form a negative pressure. In this way, the high-temperature liquid flows into the hot chamber 22 under the dual action of the thrust of the water pump 3 and the negative pressure. The amount of liquid in the cold chamber 23 meets the test requirements of multiple liquid heaters. The liquids in the cold chamber 23 and the hot chamber 22 are not limited to water, but can also be other liquids.

[0036] After one of the liquid heaters completes the performance test, the first connector 11 and the second connector 12 are connected to the new liquid heater until the liquid in the cold chamber 23 is exhausted, and the performance test of the liquid heater is stopped. At this time, the high-temperature liquid storage in the hot chamber 22 is maximized; then the test box 1 is pushed to the test area of ​​the liquid cooler, and the liquid inlet connector and the liquid outlet connector of the liquid cooler are connected to the first connector 11 and the second connector 12 respectively, and then the rotating ring 8 is rotated to drive the two S-shaped blocks 9 to rotate until the S-shaped blocks 9 are rotated to the corresponding outer port and inner port, so that the first outer port is connected to the second inner port through one of the conversion chambers 91, and the first inner port is connected to the second conversion chamber through the second conversion chamber. 91 is connected to the second external port, the right port of the water pump 3 is connected to the second internal port and sucks in liquid, and the left port is connected to the first internal port and discharges liquid. When the water pump 3 is working, the high-temperature liquid in the hot chamber 22 will follow the hot water pipe 4, pass through the temperature sensor 41 on the hot water pipe 4, and the first joint 11 into the liquid cooler. The liquid cooler uses the air cooling principle to cool the high-temperature liquid. The low-temperature liquid flowing out of the liquid cooler will flow along the second joint 12 into the cold water pipe 5 and contact with the temperature sensor 41 on the cold water pipe 5, so as to realize the temperature collection of the cooled liquid. The performance of the liquid cooler is judged according to the temperature derived from the liquid cooler to meet the testing requirements of the liquid cooler.

[0037] The low-temperature liquid will enter the right port of the water pump 3 along the first external port, one of the conversion chambers 91, and the second internal port. After the operation of the water pump 3, the liquid will be discharged along the left port to the first internal port. The liquid in the first internal port will enter the second external port along the other conversion chamber 91, and finally flow into the hot chamber 22 along the cold water pipe 5 for storage. The high-temperature liquid storage capacity in the hot chamber 22 can meet the testing requirements of multiple liquid refrigerators. After the high-temperature liquid in the hot chamber 22 is exhausted, the test of the liquid refrigerator is stopped and the test of the liquid heater is then carried out.

[0038] The present invention divides the internal space of the water tank 2 into two independent chambers using a piston plate 21, so that high-temperature or low-temperature liquid can be discharged according to test requirements, thereby meeting the performance test requirements of various equipment. In addition, the tested liquids of the liquid heater and the liquid cooler can be used for each other, which is more energy-saving and environmentally friendly. The liquids in the hot chamber 22 and the cold chamber 23 are independent of each other and do not interfere with each other.

[0039] Example 2: The side of the test box 1 away from the first joint 11 is provided with an operating window 13 aligned with the swivel 8; the inner wall of the outer ring shell 6 is provided with an arc-shaped limit groove 61; a limit block 62 is slidably connected in the limit groove 61; the limit block 62 is fixedly connected to the outer edge of one of the swivels 8.

[0040] An annular driving groove 81 is provided inside the rotating ring 8 near the operating window 13; the driving groove 81 is slidingly and sealably connected to the driving plate 82; the driving plate 82 divides the driving groove 81 into a working chamber 83 and a non-working chamber 84; the non-working chamber 84 is provided near the operating window 13; the non-working chamber 84 is communicated with the external gas; the driving plate 82 is fixedly connected to the driving rod 85 on one side near the operating window 13; the driving rod 85 passes through the rotating ring 8 at one end near the operating window 13 and is fixedly connected to the driving block 86; the driving block 86 is connected to the outer wall of the rotating ring 8 by a tension spring 87; a groove 88 is provided on the arc-shaped outer wall of the rotating ring 8 near the operating window 13; a card block 89 is slidingly and sealably connected to the groove 88; the bottom of the groove 88 is communicated with the working chamber 83 through the first liquid hole 881; the inner wall of the outer ring shell 6 is provided with a plurality of card grooves 63 corresponding to the card block 89.

[0041] There are multiple grooves 88 ; the multiple grooves 88 are evenly distributed on the arc-shaped outer wall of the rotating ring 8 ; and the multiple clamping grooves 63 are correspondingly arranged to the grooves 88 .

[0042] In the initial state, the S-shaped block 9 is staggered between the corresponding outer and inner openings, the limit block 62 is located at one end of the limit slot 61, and the card block 89 is locked in the card slot 63, so that the position of the S-shaped block 9 is positioned. At this time, the test platform is used to test the liquid heater. When it is necessary to change the flow direction of the liquid in the cold water pipe 5, that is, when it is necessary to test the liquid cooler, it is necessary to operate through the operating window 13. Specifically, the driving block 86 is pulled close to the operating window 13. When the driving block 86 approaches the operating window 13, the tension of the tension spring 87 is overcome. The driving block 86 is pulled to drive the driving plate 82 to slide in the driving slot 81, so that the space of the non-working chamber 84 becomes smaller, the space of the working chamber 83 becomes larger, and the non-working chamber The space inside 84 is connected to the external gas, so it will not affect the movement of the driving plate 82. The space inside the working chamber 83 becomes larger to form a negative pressure. The liquid medium in the groove 88 will flow into the working chamber 83 along the first liquid hole 881, and the block 89 will move out of the corresponding groove 63 and retract into the groove 88, thereby unlocking the swivel 8. In this way, the swivel 8 can be rotated to drive the two S-shaped blocks 9 on the inside to rotate. During the rotation of the swivel 8, the limit block 62 on the arc-shaped outer wall will be driven to slide along the limit groove 61. After the limit block 62 slides to the other end of the limit groove 61, the S-shaped block 9 moves to between the corresponding outer port and the inner port, so that the liquid flow direction in the cold water pipe 5 can be changed, and the limit block 62 serves the purpose of rotating and positioning the swivel 8.

[0043] After the swivel 8 rotates to the extreme position, the driving block 86 is released. The driving block 86 is pulled away from the operating window 13 by the tension spring 87, and the driving block 86 drives the driving rod 85 and the driving plate 82 to move. The driving plate 82 slides along the driving groove 81 and squeezes the working chamber 83. The liquid medium in the working chamber 83 flows into the groove 88 along the first liquid hole 881. The block 89 in the groove 88 is pushed by the liquid and is stuck in the corresponding groove 63, thereby locking the swivel 8. In this way, when the water pump 3 impacts the S-shaped block 9, the swivel 8 will not rotate or shift, making the testing process of the test platform more stable. In addition, in this embodiment, since there are multiple grooves 88, multiple grooves 88 are aligned with the corresponding grooves 63 after the swivel 8 rotates, and the blocks 89 in multiple grooves 88 will be stuck in the corresponding grooves 63, thereby further improving the locking strength of the swivel 8 after rotation.

[0044] Example 3: The S-shaped block 9 is provided with an avoidance groove 92 on the end face close to the outer wall of the inner ring shell 7 and the inner wall of the outer ring shell 6; an elastic sealing bag 93 is fixedly connected to the avoidance groove 92; the interior of the elastic sealing bag 93 is connected to the interior of the working chamber 83 through a second liquid hole 94; the second liquid hole 94 is provided inside the S-shaped block 9.

[0045] The outer wall of the inner ring shell 7 and the inner wall of the outer ring shell 6 are aligned with the position of the S-shaped block 9 after movement, and reinforcement grooves 71 are provided.

[0046] Before rotating the swivel 8 to drive the S-shaped block 9 to move, it is necessary to pull the driving block 86 close to the operating window 13, so that the space in the working chamber 83 becomes larger and forms a negative pressure, and the liquid medium in the elastic sealing bag 93 will flow into the working chamber 83 along the second liquid hole 94, so that the elastic sealing bag 93 will shrink and retract into the avoidance groove 92 for avoidance. Then the swivel 8 is controlled to rotate. During the rotation of the swivel 8, the two S-shaped blocks 9 will be driven to move, and the S-shaped block 9 will drive the elastic sealing bag 93 in the avoidance groove 92 to move. Since the elastic sealing bag 93 is retracted into the avoidance groove 92 for avoidance, the elastic sealing bag 93 does not contact the inner wall of the outer ring shell 6 and the outer wall of the inner ring shell 7, thereby improving the service life of the elastic sealing bag 93 without wear; after the S-shaped block 9 rotates to the corresponding position along with the swivel 8, the driving block 86 is released. , the space of the working chamber 83 will become smaller, and the liquid medium in the working chamber 83 will flow along the second liquid hole 94 into the elastic sealing bag 93 in the avoidance groove 92. The elastic sealing bag 93 is equivalent to a sealing ring that can be elastically deformed. After the liquid medium enters the elastic sealing bag 93, the elastic sealing bag 93 is pressurized and expanded to press against the outer wall of the inner ring shell 7 and the inner wall of the outer ring shell 6, thereby realizing the sealing between the S-shaped block 9 and the inner wall of the outer ring shell 6 and the outer wall of the inner ring shell 7. After the S-shaped block 9 moves to the corresponding position, the avoidance groove 92 on the S-shaped block 9 is aligned with the outer wall of the inner ring shell 7 and the reinforcing groove 71 on the inner wall of the outer ring shell 6. The elastic sealing bag 93 on the S-shaped block 9 will expand into the reinforcing groove 71, which on the one hand improves the sealing strength of the elastic sealing bag 93, and on the other hand improves the sealing performance of the elastic sealing bag 93 between the S-shaped block 9 and the outer wall of the inner ring shell 7 and the inner wall of the outer ring shell 6.

[0047] Example 4: The sliding seal in the reinforcement groove 71 is connected to the anti-blocking block 72; the bottoms of the two adjacent reinforcement grooves 71 on the inner ring shell 7 are connected through a first connecting hole 73; the bottoms of the two adjacent reinforcement grooves 71 on the outer ring shell 6 are connected through a second connecting hole 74.

[0048] After one of the two adjacent reinforcing grooves 71 on the outer wall of the inner ring shell 7 enters the elastic sealing bag 93, the elastic sealing bag 93 will squeeze the anti-blocking block 72 in the reinforcing groove 71. The anti-blocking block 72 will squeeze the liquid medium in the reinforcing groove 71 under pressure. The liquid medium in the reinforcing groove 71 entering the elastic sealing bag 93 is pressed along the first connecting hole 73 to enter the other reinforcing groove 71, and the anti-blocking block 72 in the other reinforcing groove 71 is blocked at the notch of the reinforcing groove 71 under the push of the liquid medium, thereby preventing impurities in the liquid from remaining in the exposed reinforcing groove 71, achieving the purpose of anti-blocking the exposed reinforcing groove 71, and preparing for the next entry of the elastic sealing bag 93; similarly, after one of the two adjacent reinforcing grooves 71 on the inner wall of the outer ring shell 6 enters the elastic sealing bag 93, the anti-blocking block 72 in the other reinforcing groove 71 moves to the notch position of the reinforcing groove 71, which can also achieve the purpose of anti-blocking the exposed reinforcing groove 71.

[0049] Example 5: The hot chamber 22 and the cold chamber 23 are internally slidingly sealed and connected with a partition 24; the sliding direction of the partition 24 is consistent with the piston plate 21; adjacent partitions 24 are connected by springs 25; flow grooves 26 are provided on both sides of the partition 24; the flow grooves 26 on adjacent partitions 24 are arranged away from each other in the vertical direction.

[0050] The elastic forces of the plurality of springs 25 are sequentially reduced as they are away from the piston plate 21 .

[0051] As the high-temperature liquid in the hot chamber 22 enters and the low-temperature liquid in the cold chamber 23 flows out, the space in the cold chamber 23 becomes smaller, and the multiple partitions 24 in the cold chamber 23 move with the movement of the piston plate 21. The partitions 24 that are farther away from the piston plate 21 are folded first, so that the low-temperature liquid far away from the piston plate 21 can be discharged first, and the low-temperature liquid close to the piston plate 21 is discharged last. After the adjacent partitions 24 approach each other, the springs 25 will also form gaps between the adjacent partitions 24 to ensure that the liquid close to the piston plate 21 can pass through the gaps between the partitions 24 that are folded away from the piston plate 21. The arrangement of the flow grooves 26 separates the liquid on both sides of the adjacent partitions 24 and Maintain connectivity; the closer the low-temperature liquid is to the piston plate 21, the greater the impact of the high-temperature liquid in the hot chamber 22 is. By separating the liquid in the cold chamber 23 into multiple areas, on the one hand, the circulation of the liquid is met, and on the other hand, the thermal insulation requirements are better met; in the process of the high-temperature liquid in the hot chamber 22 entering, the space in the hot chamber 22 becomes larger, and the multiple partitions 24 in the hot chamber 22 are opened first the closer they are to the piston plate 21, so that the high-temperature liquid enters the hot chamber 22 first and the closer it is to the piston plate 21, thereby minimizing the impact of the low-temperature liquid in the cold chamber 23 on the high-temperature liquid in the hot chamber 22, and achieving the purpose of keeping the high-temperature liquid in the hot chamber 22 warm as much as possible.
