[0002] Charging piles are charging devices that provide energy replenishment for electric vehicles. Their function is similar to that of a gas pump in a gas station. They can be fixed to the ground or a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] During use, charging piles generate a significant amount of heat. To reduce the heat inside the charging pile host, cooling fans are typically installed inside to dissipate heat using natural air. However, the cooling effect of these fans is limited. To address this issue, this invention proposes a liquid-cooled heat exchange system. Summary of the Invention

A water guide box that runs vertically through the bottom of each set of through holes is fixedly connected to the bottom of each set of through holes. A triangular plate for separating the falling water is fixedly connected between the inner walls of the two sides of the top of the water guide box.

[0007] A partition is fixedly connected between the inner walls of the two sides of the water collection tank, and a gap is provided between the water guide box and the partition for circulating water to flow through.

[0010] Furthermore, the water collection tank has installation ports on both sides, and a filter screen and a mounting bracket are fixedly connected in the installation ports respectively. A motor is fixedly connected to one side of the mounting bracket, and a fan blade is fixedly connected to one end of the motor output shaft. The installation port is located on one side of the water guide box.

[0011] Furthermore, a mounting box with through ends is fixedly connected to the bottom of the partition, the top of the mounting box contacts the bottom of the partition, and a semiconductor cooling chip is fixedly connected to the inner top wall of the mounting box.

[0013] Furthermore, a second guide block is fixedly connected to one side of the outer wall of the water collection tank, and a through sliding frame is slidably connected inside the second guide block. The other end of the sliding frame passes around the side of the machine body and is fixedly connected to a brush plate for cleaning the filter screen. A first tension spring is fixedly connected between the second guide block and the sliding frame.

[0014] Furthermore, a support base for supporting one end of the sliding frame is fixedly connected to one side of the outer wall of the water collection tank, and multiple rollers are rotatably connected between the inner walls on both sides of the support base.

[0019] In this invention, by installing a water guide box at the bottom of the return water tank, and installing a triangular plate inside the water guide box, when the circulating water enters the return water tank, it falls onto the triangular plate through the perforation, and then the circulating water flows along the triangular plate to the side wall of the water guide box, thereby accelerating the natural heat dissipation effect of the circulating water.

At the same time, the circulating water can be naturally cooled by the fan blades and then cooled a second time by the semiconductor cooling chip, further reducing the temperature of the circulating water and improving the heat dissipation effect of the machine body. Meanwhile, the brush plate cleans the filter screen to prevent the filter screen from clogging, improve the ventilation effect, and improve its automation level. Attached Figure Description

[0031] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0032] Example 1

[0033] Reference Figures 1-6 A liquid-cooled heat exchange system, comprising:

[0034] The main body 1 has a water collection tank 2 fixedly connected to its top. A return water tank 3 is fixedly connected to the top of the water collection tank 2. The bottom of the return water tank 3 has multiple sets of perforations 4 that communicate with the water collection tank 2. The bottom of each set of perforations 4 is fixedly connected to a water guide box 5 that runs vertically through the water. Triangular plates 6 for separating the falling water are fixedly connected between the inner walls on both sides of the top of the water guide box 5. The circulating water falls into different water guide boxes 5 through the multiple perforations 4 in the return water tank 3. After entering the water guide box 5, it is dispersed to both sides by the triangular plates 6 and then flows along the inner wall of the water guide box 5 to improve the heat dissipation effect of the circulating water. Heat conduction plates 7 are fixedly connected between the water guide boxes 5.

[0035] A partition 8 is fixedly connected between the inner walls of the two sides of the water collection tank 2. A gap is provided between the water guide box 5 and the partition 8 for circulating water to flow through. The circulating water flows through the gap and passes through the partition 8, reducing the evaporation of the circulating water.

[0036] A circulating cooling mechanism is installed below the water collection tank 9 to circulate cooling water.

[0037] Reference Figure 3The circulating heat dissipation mechanism includes a first drain pipe 10, a second drain pipe 12, a first return water pipe 13, a second return water pipe 14, and a water pump 15. Multiple heat exchange pipes 11 are fixedly connected between the first drain pipe 10, the second drain pipe 12, the first return water pipe 13, and the second return water pipe 14. The heat exchange pipes 11 are located beside the inner walls on both sides of the body 1. Heat dissipation fins can be installed between the heat exchange pipes 11 on the same side to increase the heat exchange effect. A water collection trough 9 is provided between the partition plate 8 and the water collection tank 2, and the first drain pipe 10 is fixedly connected to the bottom of the water collection trough 9. The second return water pipe 14 is fixedly connected to the top of the return water tank 3. A water pump 15 is provided between the second drain pipe 12 and the first return water pipe 13. The water pump 15 is fixedly connected to the second drain pipe 12 and the water pump 15 is fixedly connected to the first return water pipe 13. When the water pump 15 is started, the water pump 15 draws circulating water, which then enters the return water tank 3 after passing through the first return water pipe 13 and the second return water pipe 14. After passing through the return water tank 3 and the water collection tank 2, it enters the first drain pipe 10 and the second drain pipe 12, and then circulates.

[0038] Example 2

[0039] Based on Example 1, in Example 2,

[0040] Reference Figures 1-6 The water collection tank 2 has installation ports on both sides. A filter screen 30 and a mounting bracket 16 are fixedly connected in the installation ports respectively. A motor 17 is fixedly connected to one side of the mounting bracket 16. A fan blade 18 is fixedly connected to one end of the output shaft of the motor 17. The installation port is located on one side of the water guide box 5. When the motor 17 starts, it drives the fan blade 18 to rotate, thereby drawing air from between the water guide boxes 5 and using natural air to dissipate heat from the falling circulating water.

[0041] Reference Figure 3 The bottom of the partition 8 is fixedly connected to a mounting box 32 with both ends extending through it. The top of the mounting box 32 contacts the bottom of the partition 8. A semiconductor cooling chip 33 is fixedly connected to the inner wall of the top of the mounting box 32. The cooling surface of the semiconductor cooling chip 33 contacts the inner wall of the top of the mounting box 32. This is an existing refrigeration technology. The working principle and usage method will not be described in detail here. The cooling effect of the circulating water is increased by using the semiconductor cooling chip 33.

[0042] Reference Figure 5A cam 19 is fixedly connected to the circumference of the output shaft of motor 17. A first guide block 20 is fixedly connected to one side of water tank 2. A slide plate 21 is slidably connected inside the first guide block 20. A through slide 22 is opened on one side of water tank 2. A lever 23 is slidably connected to the inner wall of slide 22. The lever 23 is fixed to the slide plate 21. A second tension spring 28 is fixedly connected between the first guide block 20 and the lever 23. Multiple levers 24 are fixedly connected to the bottom of lever 23. All levers 24 are located above the semiconductor cooling chip 33. After the protrusion of cam 19 contacts the slide plate 21, it pushes the slide plate 21 to move. The slide plate 21 pushes the lever 23 and levers 24 to move. Then, it is reset under the pull of the second tension spring 28, thereby agitating the circulating water passing through the semiconductor cooling chip 33 and improving the cooling effect of the circulating water.

[0043] Reference Figure 5 A second guide block 25 is fixedly connected to one side of the outer wall of the water collection tank 2. A through sliding frame 26 is slidably connected inside the second guide block 25. The other end of the sliding frame 26 passes around the side of the body 1 and is fixedly connected to a brush plate 31 for cleaning the filter screen 30. A first tension spring 27 is fixedly connected between the second guide block 25 and the sliding frame 26. The cam 19 can also push the sliding frame 26 to move and form a reciprocating motion under the pull of the first tension spring 27, so that the sliding frame 26 drives the brush plate 31 to clean the filter screen 30 back and forth, so as to avoid the filter screen 30 from being blocked and improve the natural ventilation effect.

[0044] Reference Figure 6 A support base 29 for supporting one end of the sliding frame 26 is fixedly connected to one side of the outer wall of the water collection tank 2. Multiple rollers are rotatably connected between the inner walls on both sides of the support base 29 to increase the stability of the movement of the sliding frame 26.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the water pump 15, motor 17, and semiconductor cooling chip 33 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The working principle and usage process of this technical solution are as follows: When the machine body 1 needs to circulate heat dissipation, the water pump 15, motor 17 and semiconductor cooling chip 33 are started. First, the water pump 15 draws circulating water, which then enters the return water tank 3 after passing through the first return water pipe 13 and the second return water pipe 14. It then falls into different guide boxes 5 through multiple perforations 4 in the return water tank 3. After entering the guide boxes 5, it is dispersed to both sides by the triangular plate 6 and then flows along the inner wall of the guide boxes 5. When the motor 17 is started, it drives the fan blade 18 to rotate, thereby drawing air between the guide boxes 5. Natural air is used to dissipate heat from the falling circulating water. At the same time, the action of the guide boxes 5 under the circulating water reduces evaporation and the number of water replenishment times.

[0047] After being cooled naturally, the water is cooled again by the semiconductor cooling chip 33, providing a cooling effect. Then it falls into the water collection tank 9 and is drawn back into the body 1 to cool the body 1.

[0048] While the motor 17 is starting, it also drives the cam 19 to rotate. After the protrusion of the cam 19 contacts the slide plate 21, it pushes the slide plate 21 to move. The slide plate 21 pushes the lever 23 and the lever 24 to move. Then, it is reset under the pull of the second tension spring 28, which in turn moves the circulating water passing through the semiconductor cooling chip 33 to improve the cooling effect of the circulating water. After the protrusion of the cam 19 contacts the sliding frame 26, it pushes the sliding frame 26 to move and forms a reciprocating motion under the pull of the first tension spring 27. This causes the sliding frame 26 to drive the brush plate 31 to clean the filter screen 30 back and forth, preventing the filter screen 30 from clogging and improving the natural ventilation effect.

[0049] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
