Description

Technical Field

[0001] This invention belongs to the field of charging pile heat dissipation technology, specifically referring to a heat dissipation device for new energy charging piles. Background Technology

[0002] With technological advancements, new energy vehicles, powered by electricity and possessing advantages such as energy conservation and environmental friendliness, are gradually becoming a part of everyday life. As the equipment providing charging services for new energy vehicles, charging stations are playing an increasingly important role. However, most charging stations lack heat dissipation designs, and in high-temperature seasons, especially summer, the internal temperature of the charging station can easily rise after prolonged operation. This high-temperature environment can damage internal circuitry and circuit boards, and in severe cases, may even lead to explosions and other safety accidents, causing unnecessary losses and potential hazards.

[0003] The existing heat dissipation equipment for new energy charging piles currently has the following problems:

[0004] The existing heat dissipation equipment of new energy charging piles cannot adjust the contact time between the incoming airflow and the heat dissipation components according to the outside air temperature, which will cause two problems: First, the contact time between the relatively high outside temperature air and the heat dissipation components is longer, which affects the heat dissipation efficiency; Second, the contact time between the relatively low outside temperature air and the heat dissipation components is shorter, which cannot fully cool the heat dissipation components and reduce the heat exchange efficiency.

[0005] Furthermore, the traditional heat dissipation equipment for new energy charging piles uses air filtration to allow airflow to directly contact the charging pile. As dust accumulates on the filter surface, airflow decreases, which cannot meet the heat dissipation requirements of the charging pile during operation.

[0006] Therefore, there is an urgent need for a device that can fully utilize outside air to dissipate heat from charging stations. Summary of the Invention

[0007] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a heat dissipation device for new energy charging piles that can adjust the contact time between the incoming airflow and the heat dissipation components in a timely manner according to the outside air temperature, thereby improving the filtration efficiency of the outside air on the charging pile and preventing outside dust from entering the charging pile with the airflow.

[0008] The technical solution adopted in this plan is as follows: This plan proposes a heat dissipation device for new energy charging piles, including a charging shell, a heat dissipation shell, an air guiding mechanism, a wind-facing mechanism, a temperature measuring mechanism, and a buoyancy measuring mechanism. The heat dissipation shell is connected to one side of the charging shell, the air guiding mechanism is located above the heat dissipation shell, the wind-facing mechanism is located inside the air guiding mechanism, the temperature measuring mechanism is located at the end of the air guiding mechanism near the heat dissipation shell, and the buoyancy measuring mechanism is located on the temperature measuring mechanism. The air guiding mechanism includes an air intake component and a conduction component. The air intake component is located on the upper wall of the heat dissipation shell, and the conduction component penetrates through the inner wall of the end of the heat dissipation shell away from the charging shell. The wind-facing mechanism includes a heat exchange component and a wind control component. The heat exchange component is located inside the conduction component, and the wind control component is located on the side of the conduction component away from the heat dissipation shell. The temperature measuring mechanism includes a pushing component and a sensing component. The pushing component is located at the end of the conduction component near the heat dissipation shell, and the sensing component is located on the upper wall of the pushing component.

[0009] As a further preferred embodiment of the present invention, the air-exhausting assembly includes an arc-shaped box, an air-exhausting duct, and an air-exhausting fan. The arc-shaped box is disposed on the upper wall of the heat sink housing, the air-exhausting ducts are symmetrically disposed on both sides of the arc-shaped box, and the air-exhausting ducts are through-type. The air-exhausting fan is disposed inside the air-exhausting duct. The conduction assembly includes an air-guide box, cylindrical grooves, conductive copper pipes, exhaust valves, and air-guide pipes. The air-guide box is disposed through-type on the inner wall of the end of the heat sink housing away from the charging housing. Multiple sets of cylindrical grooves are disposed on the side of the air-guide box near the heat sink housing, and the cylindrical grooves are through-type. The conductive copper pipes are disposed inside the cylindrical grooves. Multiple sets of exhaust valves are connected and disposed on the bottom wall of the air-guide box, and multiple sets of air-guide pipes are connected and disposed between the arc-shaped box and the upper wall of the air-guide box.

[0010] During use, cooling water is added to the copper conduction pipe, and the exhaust fan draws outside air into the arc-shaped box. The air inside the arc-shaped box flows into the air guide box through the air duct. The air flows vertically downward, carrying away the heat inside the copper conduction pipe. The heat-exchanged air is discharged through the exhaust valve. The vertical downward airflow is in the same direction as gravity, which can accelerate the settling of dust particles in the air, making it easier to discharge them from the air guide box. This reduces the chance of dust in unfiltered air accumulating inside the air guide box and ensures the air permeability inside the air guide box.

[0011] Preferably, the heat exchange assembly includes spring tubes and arc-shaped copper tubes. Multiple sets of spring tubes are connected and disposed on the side of the conductive copper tubes near the air guide box, with the length of the spring tubes increasing sequentially from top to bottom. The arc-shaped copper tubes are connected and disposed on the side of the spring tubes away from the conductive copper tubes, with the distance between the arc-shaped copper tubes and the inner wall of the air guide box increasing sequentially from top to bottom. The air control assembly includes an air control magnetic sleeve, an air control rod, and an electromagnet. Multiple sets of air control magnetic sleeves are disposed through the air guide box on the side away from the heat dissipation shell. The air control rod is disposed between the air control magnetic sleeve and the arc-shaped copper tubes, and the air control rod is slidably connected to the air control magnetic sleeve. The electromagnet is disposed at the end of the air control rod away from the arc-shaped copper tube.

[0012] During use, cooling water is filled into the arc-shaped copper tube and the spring tube. The conductive copper tube is connected to the arc-shaped copper tube through the spring tube. The spring tube is normally extended. From a top view, the arc-shaped copper tube is a flat surface with no gaps between it. This allows the relatively cool vertical airflow from the air duct into the air box to fully impact the surface of the arc-shaped copper tube, improving the cooling efficiency of the outside air on the arc-shaped copper tube. The arc-shaped copper tube cools the cooling water inside it. The cooling water absorbs heat and cools the space inside the charging shell and heat dissipation shell through the conductive copper tube, thus ensuring that the operating temperature of the charging pile does not become too high.

[0013] Specifically, the pushing assembly includes a temperature measuring groove, a connecting sleeve, a temperature measuring cylinder, and a piston plate. The temperature measuring groove is located on the side wall of the air guide box above the cylindrical groove. The temperature measuring cylinder is located inside the temperature measuring groove. The connecting sleeve is connected between the temperature measuring cylinder and the conductive copper pipe. The piston plate is slidably located on the inner wall of the temperature measuring cylinder. The sensing assembly includes a sensing element and a distance sensor. The sensing element is disposed through the upper wall of the temperature measuring cylinder and on the upper wall of the piston plate.

[0014] When in use, when the temperature of the cooling water inside the conductive copper tube rises, some water vapor is generated. The water vapor flows upward through the gap between the inner wall of the connecting sleeve and the lightweight float and enters the temperature measuring cylinder below the piston plate. As the steam accumulates inside the temperature measuring cylinder below the piston plate, the piston plate is pushed to slide upward along the inner wall of the temperature measuring cylinder. The piston plate drives the sensing element to rise. At this time, the distance between the sensing element and the distance measuring end of the distance measuring sensor is shortened.

[0015] The buoyancy measuring mechanism includes a lightweight float and a lightweight buoy. The lightweight float is installed on the bottom wall of the piston plate through a connecting sleeve, and the diameter of the lightweight float is smaller than the inner diameter of the connecting sleeve. The lightweight buoy is installed on the bottom wall of the lightweight float, and the diameter of the lightweight buoy is smaller than the inner diameter of the conductive copper tube.

[0016] In use, a lightweight float is suspended in the cooling water. The lightweight float drives the piston plate to the middle position of the temperature measuring cylinder through a lightweight float rod. When the distance measuring end of the distance measuring sensor detects that the distance between it and the sensing plate has shortened, it indicates that the temperature of the cooling water inside the conductive copper pipe has increased. When the distance measuring end of the distance measuring sensor detects that the distance between it and the sensing plate has increased, it indicates that the amount of cooling water inside the conductive copper pipe has decreased.

[0017] The beneficial effects achieved by this solution using the above structure are as follows:

[0018] Compared with existing technologies, this solution adopts a combination of air guiding mechanism, wind-facing mechanism, temperature measuring mechanism, and buoyancy measuring mechanism. Through the setting of air-inducing component, conduction component, heat exchange component, air control component, pushing component, and sensing component, it can adjust the contact area and contact resistance between the vertical airflow and the arc-shaped copper pipe in a timely manner according to the temperature of the cooling water inside the conduction copper pipe. This changes the flow speed of the airflow inside the air guide box, thereby improving the cooling and heat dissipation efficiency of the natural wind on the internal space of the charging shell and heat dissipation shell, thus ensuring the stable operation of the charging pile. The relatively low-temperature vertical airflow discharged into the air guide box by the air guide pipe can completely impact the surface of the arc-shaped copper pipe, improving the cooling efficiency of the arc-shaped copper pipe by the outside air. The arc-shaped copper pipe cools the cooling water inside it, and the cooling water absorbs heat and cools the internal space of the charging shell and heat dissipation shell through the conduction copper pipe.

[0033] like Figures 1-10As shown, this solution proposes a heat dissipation device for new energy charging piles, including a charging shell 1, a heat dissipation shell 2, an air guiding mechanism 3, a wind-facing mechanism 13, a temperature measuring mechanism 21, and a buoyancy measuring mechanism 30. The heat dissipation shell 2 is connected to one side of the charging shell 1. The air guiding mechanism 3 is located above the heat dissipation shell 2.

The air intake component 4 is disposed on the upper wall of the heat dissipation shell 2, and the conduction component 8 is disposed through the inner wall of the heat dissipation shell 2 at the end away from the charging shell 1. The air intake mechanism 13 includes a heat exchange component 14 and an air control component 17.

[0034] The air intake assembly 4 includes an arc-shaped box 5, an air intake duct 6, and an air intake fan 7. The arc-shaped box 5 is located on the upper wall of the heat dissipation shell 2. The air intake duct 6 is symmetrically located on both sides of the arc-shaped box 5 and is a through-type air intake duct. The air intake fan 7 is located inside the air intake duct 6. The conduction assembly 8 includes an air guide box 9, a cylindrical groove 10, a conduction copper pipe 11, an exhaust valve 12, and an air guide pipe 33. The air guide box 9 is located through-type air intake duct 10 on the inner wall of the end of the heat dissipation shell 2 away from the charging shell 1. Multiple sets of cylindrical grooves 10 are located on the side of the air guide box 9 close to the heat dissipation shell 2 and are a through-type air intake duct. The conduction copper pipe 11 is located inside the cylindrical groove 10. Multiple sets of exhaust valves 12 are connected to the bottom wall of the air guide box 9. Multiple sets of air guide pipes 33 are connected between the arc-shaped box 5 and the upper wall of the air guide box 9.

[0035] The heat exchange assembly 14 includes a spring tube 15 and an arc-shaped copper tube 16. Multiple sets of the spring tubes 15 are connected and disposed on the side of the conductive copper tube 11 near the air guide box 9. The length of the spring tubes 15 increases sequentially from top to bottom. The arc-shaped copper tube 16 is connected and disposed on the side of the spring tubes 15 away from the conductive copper tube 11. The distance between the arc-shaped copper tube 16 and the inner wall of the air guide box 9 increases sequentially from top to bottom. The air control assembly 17 includes an air control magnetic sleeve 18, an air control rod 19, and an electromagnet 20. Multiple sets of the air control magnetic sleeves 18 are disposed through the air guide box 9 on the side away from the heat dissipation shell 2. The air control rod 19 is disposed between the air control magnetic sleeve 18 and the arc-shaped copper tube 16. The air control rod 19 and the air control magnetic sleeve 18 are slidably connected. The electromagnet 20 is disposed at the end of the air control rod 19 away from the arc-shaped copper tube 16.

[0036] The pushing assembly 22 includes a temperature measuring groove 23, a connecting sleeve 24, a temperature measuring cylinder 25, and a piston plate 26. The temperature measuring groove 23 is located on the side wall of the air guide box 9 above the cylindrical groove 10. The temperature measuring cylinder 25 is located inside the temperature measuring groove 23. The connecting sleeve 24 is connected between the temperature measuring cylinder 25 and the conductive copper pipe 11. The piston plate 26 is slidably located on the inner wall of the temperature measuring cylinder 25. The sensing assembly 27 includes a sensing element 28 and a distance sensor 29. The sensing element 28 is located through the upper wall of the temperature measuring cylinder 25 and on the upper wall of the piston plate 26.

[0037] The buoyancy measuring mechanism 30 includes a lightweight float 31 and a lightweight float 32. The lightweight float 31 is disposed on the bottom wall of the piston plate 26 through the connecting sleeve 24. The diameter of the lightweight float 31 is smaller than the inner diameter of the connecting sleeve 24. The lightweight float 32 is disposed on the bottom wall of the lightweight float 31. The diameter of the lightweight float 32 is smaller than the inner diameter of the conductive copper tube 11.

[0038] In practical use, the new energy vehicle charging pile is installed in the space inside the charging shell 1 and the heat dissipation shell 2. Cooling water is added into the conductive copper pipe 11, the spring pipe 15 and the arc-shaped copper pipe 16. The conductive copper pipe 11 and the arc-shaped copper pipe 16 are connected through the spring pipe 15. The lightweight float 32 is suspended in the cooling water inside the conductive copper pipe 11. The lightweight float 32 drives the piston plate 26 to the middle position of the temperature measuring cylinder 25 through the lightweight float rod 31, which controls the start of the distance measuring sensor 29. The distance measuring sensor 29 monitors the distance between itself and the sensing plate 28 through the distance measuring end.

[0039] The spring tube 15 is normally extended. From a top view, the arc-shaped copper tube 16 is a flat surface with no gaps between them. When the exhaust fan 7 is started, it draws outside air into the arc-shaped box 5. The air inside the arc-shaped box 5 flows into the air guide box 9 through the air guide pipe 33. The relatively cool vertical airflow entering the air guide box 9 impacts the surface of the arc-shaped copper tube 16. The airflow is blocked by the arc-shaped copper tube 16, which prolongs the contact time with the airflow, thus enabling sufficient heat exchange with the cooling water inside the arc-shaped copper tube 16. The cooling water absorbs heat and cools the internal space composed of the charging shell 1 and the heat dissipation shell 2 through the conduction copper tube 11, thereby ensuring that the operating temperature of the charging pile is not too high.

[0040] After the impact heat exchange, the airflow flows downward through the area between the upper and lower walls of the arc-shaped copper tube 16 with a height difference. The vertical downward airflow is in the same direction as gravity, which can accelerate the settling of dust particles in the air and facilitate their discharge from the air guide box 9. This reduces the chance of dust in the unfiltered air accumulating inside the air guide box 9 and ensures the air permeability inside the air guide box 9. The heat-exchanged air is discharged through the exhaust valve 12.

[0041] When the outside air temperature rises, the airflow impacts the seamless arc-shaped copper tube 16 from a planar perspective, which prolongs the contact time between the relatively hot airflow and the arc-shaped copper tube 16. This reduces the heat dissipation efficiency of the cooling water in the conductive copper tube 11 and the arc-shaped copper tube 16 to the internal space of the charging shell 1 and the heat dissipation shell 2, causing the charging pile inside the charging shell 1 and the heat dissipation shell 2 to operate at a relatively high temperature. The cooling water in the conductive copper tube 11 is affected by the heat inside the charging shell 1 and the heat dissipation shell 2, which raises the temperature and generates some water vapor. The water vapor flows upward through the gap between the inner wall of the connecting sleeve 24 and the lightweight float 31 and enters the temperature measuring cylinder 25 below the piston plate 26. As the steam accumulates inside the temperature measuring cylinder 25 below the piston plate 26, the piston plate 26 is pushed to slide upward along the inner wall of the temperature measuring cylinder 25. The piston plate 26 drives the sensing plate 28 to rise. At this time, the distance between the sensing plate 28 and the measuring end of the ranging sensor 29 is shortened.

[0042] The control electromagnet 20 is energized to generate magnetism. The magnetic poles of the electromagnet 20 are N pole, S pole, N pole, and S pole from bottom to top. The magnetic poles of the control magnetic sleeve 18 set on the side wall of the air guide box 9 are all S poles. This causes the arc-shaped copper tube 16 to move from bottom to top, pushing and pulling out, pushing and pulling out, respectively. This widens the gap of the arc-shaped copper tube 16 in the plane view, so that the relatively high temperature airflow can quickly pass through the inside of the air guide box 9. The faster airflow velocity inside the air guide box 9 is used to reduce the temperature of the cooling water inside the arc-shaped copper tube 16 and the conductive copper tube 11, thereby ensuring the heat dissipation efficiency of the charging shell 1 and the heat dissipation shell 2 and ensuring the stable operation of the charging pile.

[0043] After the level of cooling water in the conductive copper pipe 11 drops, the lightweight float 32 drives the piston plate 26 to slide down along the inner wall of the temperature measuring cylinder 25 via the lightweight float rod 31. The distance between the sensing plate 28 and the measuring end of the ranging sensor 29 increases, requiring the injection of cooling water into the arc-shaped copper pipe 16 and the conductive copper pipe 11. The above operation can be repeated for the next use.

[0045] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this.
