Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to a liquid-cooled supercharging pile and its temperature control system capable of autonomous temperature control. Background Technology

[0002] Supercharging stations are high-power output fast charging devices that can significantly shorten the charging time of electric vehicles and solve the problem of low charging efficiency in traditional charging methods. Because supercharging stations operate at high power during charging, they generate a significant amount of heat. This heat needs to be dissipated promptly to ensure safe operation. Currently, supercharging stations use liquid cooling, which is effective. Liquid cooling primarily uses liquid cooling plates to remove heat from the supercharging station. However, existing supercharging stations do not allow for quick installation and removal of the liquid cooling plates, making later inspection and maintenance inconvenient. Furthermore, existing supercharging stations cannot utilize the flow of coolant to open and close the vents in conjunction with air cooling to improve heat dissipation while preventing external dust from entering the supercharging station through the vents. Summary of the Invention

[0003] The purpose of this invention is to provide a liquid-cooled supercharging pile and its temperature control system that can achieve autonomous temperature control, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A liquid-cooled supercharging pile capable of autonomous temperature control includes: a charging pile body, an internal cavity being formed on the charging pile body, an installation support plate being fixedly arranged in the internal cavity, and an internal groove being formed on the charging pile body below the internal cavity. A liquid-cooled drive assembly is installed in an internal tank to drive the coolant to circulate. A liquid cooling plate is installed in an internal cavity and connected to a liquid cooling drive assembly, and a movable connection assembly is installed on the liquid cooling plate; A locking plate assembly, which is also installed in the built-in cavity, provides double locking for the liquid cooling plate; The air-cooling auxiliary mechanism cooperates with the movable connecting component, and is moved by the movable connecting component to provide auxiliary air-cooling heat dissipation for the interior cavity.

[0005] Preferably, the liquid-cooled drive assembly includes a pump body, a liquid storage tank, and a condenser, and a circulation pipe is provided between the pump body, the liquid storage tank, and the condenser to connect the three components.

[0006] Preferably, an inlet pipe and an outlet pipe are fixedly provided on the liquid cooling plate, the inlet pipe is connected to one end of the circulation pipe, and the outlet pipe is connected to the other end of the circulation pipe.

[0007] Preferably, the movable connection component is a movable connecting pipe, which is movably installed on the liquid outlet pipe, and the liquid outlet pipe is connected to the circulation pipe through the movable connecting pipe.

[0008] Preferably, the locking plate assembly includes: a threaded lever, which is mounted on the mounting plate; Locking strip, which is also mounted on the mounting plate; A locking plate frame is movably connected to a locking plate strip, and the locking plate frame is moved by the locking plate strip; The locking ring is also movably connected to the locking strip, and the locking strip drives the locking ring to move.

[0009] Preferably, the threaded lever is threadedly connected to the locking plate, and the locking plate is moved up and down by the threaded lever.

[0010] Preferably, a support plate is movably mounted on the locking plate, and the locking plate is locked by the cooperation between the support plate and the locking ring.

[0011] Preferably, the locking strip presses down and fixes the liquid cooling plate, and the locking plate frame and locking plate ring insert and fix the liquid cooling plate.

[0012] Preferably, the air-cooling auxiliary mechanism includes: a drive support block, which cooperates with the movable connecting pipe and drives it to move downward through the movable connecting pipe; A drive base frame is movably connected to a drive support block, and the drive support block drives the base frame to move. A sealing plate is movably connected to a drive base frame, and the drive base frame drives it to rotate. A cooling fan is fixedly installed in the built-in cavity.

[0013] A temperature control system includes a temperature sensing module, a transmission module, and a central controller module. The temperature sensing module senses the temperature in the built-in cavity and transmits the high-temperature information to the central controller module through the transmission module. The central controller module controls the pump, condenser, and cooling fan to perform heat dissipation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. When installing the liquid cooling plate, place it on the mounting plate, connect its inlet and outlet pipes to the circulation pipe to position the liquid cooling plate, and then rotate the threaded lever to move the locking plate downward. As the locking plate moves downward, the pressure plate at its upper end will press on the upper end of the liquid cooling plate to initially fix it. At the same time, the locking plate can automatically lock to ensure the stability of the liquid cooling plate installation.

[0015] 2. When the locking plate moves downward, it will drive the locking plate frame and locking plate ring to move in opposite directions, clamping the liquid cooling plate. At the same time, the first locking pin on the locking plate frame and the second locking pin on the locking plate ring are inserted into the locking holes of the plate body to further fix the liquid cooling plate, fully ensuring the firmness of the liquid cooling plate installation. The operation is simple, convenient and quick.

[0016] 3. In addition, when the coolant in the liquid cooling plate flows out from the outlet pipe, it will drive the movable connecting pipe to move downward. As the movable connecting pipe moves downward, it will push the drive support block to move downward. Under the action of the drive support block, the drive base frame will move. The drive base frame will drive the sealing plate to rotate, so that the heat dissipation slot is in the open state. This can realize air cooling. The heat dissipation fan will dissipate the heat inside the charging pile body. When there is no cooling, the heat dissipation slot is closed by the sealing plate to prevent external dust from entering the internal cavity. Attached Figure Description

That is, the lower end of the movable connecting pipe 58 is inserted into the connecting pipe sleeve 44 at the other end of the circulation pipe 43. A mating guide rod 59 is welded to the lower end of the liquid cooling plate 5. The mating guide rod 59 is inserted into the mating through hole 585. A first spring 591 is sleeved on the mating guide rod 59. The two ends of the first spring 591 are respectively welded to the liquid cooling plate 5 and the outer connecting plate 584.

[0038] like Figure 2 , Figure 6 , Figure 11 , Figure 12 and Figure 13 The locking plate assembly includes: a threaded lever 25, a locking plate strip 6, a locking plate frame 7, and a locking plate ring 8. A bearing 24 is sleeved on the threaded lever 25 and inserted into the assembly hole 23. The locking plate strip 6 is mounted on the mounting plate 2. The locking plate frame 7 is movably connected to the locking plate strip 6, and the locking plate frame 7 is moved by the locking plate strip 6. The locking plate ring 8 is also movably connected to the locking plate strip 6, and the locking plate ring 8 is moved by the locking plate strip 6.

[0039] The locking plate 6 has a threaded through hole 61. The threaded lever 25 is threadedly connected to the locking plate 6 through the threaded through hole 61. The locking plate 6 is moved up and down by the threaded lever 25. The locking plate 6 has an integrally formed support frame 62. The upper end of the support frame 62 has an integrally formed pressure plate 63. The locking plate 6 also has an installation bearing hole 64.

[0040] A bearing strip 65 is movably mounted on the locking strip 6. A mounting support rod 66 is integrally formed symmetrically on the bearing strip 65. The mounting support rod 66 is inserted into the mounting support hole 64, and a second spring 67 is sleeved on the mounting support rod 66. The two ends of the second spring 67 are welded to the locking strip 6 and the bearing strip 65 respectively. In addition, a locking bar post 68 is welded to the bearing strip 65. A lower extension strip 82 is integrally formed at the lower end of the locking ring 8. A mating insertion hole 83 is opened on the lower extension strip 82. When the locking strip 6 is locked by the cooperation of the bearing strip 65 and the locking ring 8, the locking bar post 68 is inserted into the mating insertion hole 83.

[0041] When the locking plate 6 presses down to fix the liquid cooling plate 5, the pressure plate 63 presses on the upper end surface of the liquid cooling plate 5. The two sides of the locking plate 6 are symmetrically integrally formed with protruding support brackets 69. The protruding support brackets 69 are symmetrically hinged with movable connecting rods 691. The other end of one movable connecting rod 691 is hinged to a locking plate frame 7, and the other end of the other movable connecting rod 691 is hinged to a locking plate ring 8. The locking plate frame 7 is symmetrically welded with a first locking post 71, and the locking plate ring 8 is symmetrically welded with a second locking post 81. When the locking plate frame 7 and the locking plate ring 8 are inserted to fix the liquid cooling plate 5, the first locking post 71 and the second locking post 81 are both inserted into the locking hole 51 of the plate body.

[0042] like Figure 2 , Figure 3 and Figure 14 As shown, the air-cooled auxiliary mechanism includes: a drive support block 9, a drive base frame 94, a sealing plate 10, and a cooling fan 104. The drive support block 9 cooperates with the movable connecting pipe 58, and is driven to move downwards through the movable connecting pipe 58. The drive support block 9 has a limiting guide hole 91 and a insertion through hole 92. A limiting support rod 3 is inserted into the limiting guide hole 91, and a matching guide rod 59 is inserted into the insertion through hole 92. The drive support block 9 is located below the outer connecting plate 584 and is in contact with the outer connecting plate 584. A drive connecting rod 93 is hinged to the drive base frame 94. The upper end of the drive connecting rod 93 is hinged to the drive support block 9, and is driven to move through the drive support block 9. The drive base frame 94 is inserted into the insertion channel 15, and the drive base frame 9... A connecting strip 95 is symmetrically welded and fixed on the 4. A connecting plate groove 96 is opened on the connecting strip 95. A hinge shaft 101 is inserted into the upper end of the sealing plate 10, and the sealing plate 10 is hinged to the mounting strip 17 through the hinge shaft 101. In addition, a bearing strip 102 is symmetrically welded and fixed on the sealing plate 10. A connecting rod 103 is welded between the bearing strips 102. The connecting rod 103 is inserted into the connecting plate groove 96 and contacts the inner wall of the connecting plate groove 96. The sealing plate 10 is driven to rotate by the drive base frame 94. When the sealing plate 10 is in a vertical state, it covers the heat dissipation groove 13 and contacts the support protrusion ring 16. The cooling fan 104 is fixedly installed in the built-in cavity 11 and is located on the opposite side of the heat dissipation groove 13.

[0043] like Figure 15As shown, a temperature control system includes a temperature sensing module, a transmission module, and a central controller module. The temperature sensing module senses the temperature in the built-in cavity 11 and transmits the high temperature information to the central controller module through the transmission module. The central controller module controls the pump body 4, the condenser 42, and the cooling fan 104 to perform heat dissipation.

[0044] During the installation of the liquid cooling plate 5, its inlet pipe 52 is connected to the connecting sleeve 44 at one end of the circulation pipe 43, and the movable connecting pipe 58 is connected to the connecting sleeve 44 at the other end of the circulation pipe 43. Simultaneously, the liquid cooling plate 5 is lowered onto the mounting plate 2 to complete its positioning. At this point, the threaded lever 25 is rotated, causing the locking plate 6 to move downwards under the action of the thread. This causes the pressure plate 63 on the locking plate 6 to press down and fix the liquid cooling plate 5. As the locking plate 6 moves downwards, the movable connecting rod 691 causes the locking plate frame 7 and the locking plate ring 8 to move towards each other. At this time, the lower extension bar 82 will contact the locking bar post 68. Thus, as the locking plate ring 8 moves, the lower extension bar 82 pushes the locking plate frame 7 and the locking plate ring 8 towards each other. The moving locking bar post 68 moves, thereby compressing the second spring 67 until the locking plate ring 8 and locking plate frame 7 come into contact with the liquid cooling plate 5 and clamp it, providing auxiliary support. Simultaneously, the first locking post 71 and the second locking post 81 are inserted into the locking holes 51 of the plate body to secure the liquid cooling plate 5, ensuring the firmness of the liquid cooling plate 5 installation. At this time, the locking bar post 68 is aligned with the mating insertion hole 83. Under the action of the second spring 67, the carrying plate 65 moves in the opposite direction, causing the locking bar post 68 to insert into the mating insertion hole 83 to lock the locking plate 65, thereby locking the threaded lever 25 and preventing it from rotating. During liquid cooling, coolant flows from the outlet... As the coolant flows back down from pipe 56 to circulation pipe 43, it acts on the inner support plate 581. This coolant action causes the movable connecting pipe 58 to move downwards, allowing the connecting sleeve 44, connected to the outlet pipe 56, to be inserted into the connecting cavity 586, further strengthening the seal at the connection. Simultaneously, as the movable connecting pipe 58 moves downwards, the outer connecting plate 584 pushes the drive support block 9 downwards, which in turn pushes the drive base frame 94 to move under the action of the drive connecting rod 93. This, in turn, with the cooperation of the connecting plate groove 96 and the connecting rod 103, causes the sealing plate 10 to rotate, opening the heat dissipation slot 13. This allows for auxiliary heat dissipation of the internal cavity 11 via air cooling, further... To improve heat dissipation efficiency, when the charging pile body 1 does not require heat dissipation, the coolant flows back. Under the action of the first spring 591, the movable connecting pipe 58 moves upward and resets. At the same time, the sealing plate 10 rotates downward and resets under its own gravity, which in turn drives the drive bearing block 9 to reset. The sealing plate 10 covers the heat dissipation groove 13 again to seal it, preventing external dust from entering the internal cavity 11. When it is necessary to remove the liquid cooling plate 5, push the bearing plate 65 to make the locking bar 68 disengage from the mating hole 83, so that the locking plate 6 is in the unlocked state. Then, rotate the threaded lever 25 in the opposite direction to move the locking plate 6 upward to unlock the liquid cooling plate 5, which is convenient and quick to remove. The operation is simple and fast.
