Description

Technical Field

[0001] This invention relates to the field of electric vehicle power supply device manufacturing technology, specifically to a high-efficiency heat dissipation new energy vehicle charging pile. Background Technology

[0002] New energy charging piles, also known as electric vehicle power supply equipment, are special devices that provide power to the power batteries of electric vehicles. They are similar to gas stations for gasoline vehicles and are the core infrastructure for the development of the electric vehicle industry.

[0003] Currently, the biggest challenge for new energy charging piles after they are put into use is how to solve the overheating problem of the charging gun during the charging process. When the vehicle is charging at high speed, the connection between the charging gun and the vehicle's charging port, as well as the inside of the charging gun's cable, are prone to overheating. There are usually two ways to cool them: passive cooling and forced cooling. Forced cooling is divided into air cooling and water cooling. However, with the continuous increase in charging power, air cooling is no longer effective in cooling down. Water cooling involves placing a circulating water cooling system inside the charging gun and charging cable for liquid cooling circulation. Currently, existing liquid cooling systems usually use a water tank and a water pump for circulating cooling. However, after continuous high-power charging, the water temperature in the tank rises to a certain level and completely loses its liquid cooling effect. Therefore, a new energy charging pile with good heat dissipation capacity is needed to solve this problem. Summary of the Invention

[0008] Preferably, the inner wall of the air duct is provided with a spiral groove.

[0009] Preferably, a cooling water tank is fixedly installed on the inner wall of the fixed frame, a water inlet pipe is fixedly connected to the outer wall of the cooling water tank, a water pump is fixedly installed on the cooling water tank, a water cooling pipe is fixedly connected to the output end of the water pump, a heat dissipation water pipe is fixedly connected to one end of the water cooling pipe, a heat dissipation water pipe is fixedly installed on the outer wall of the heat dissipation water pipe, a plurality of evenly distributed first vent holes are opened on the heat dissipation water pipe, an air guide pipe is fixedly connected to the outer wall of the fixed frame, and the other end of the air guide pipe is fixedly connected to the inner wall of the charging pile housing.

[0010] Preferably, both ends of the heat dissipation water pipe are fixedly connected to water cooling pipes, the inner wall of the charging pile housing is fixedly installed with a charging pile control motherboard, the inner wall of the charging pile housing is fixedly installed with multiple circuit breakers, a charging cable is fixedly connected to the circuit breaker, a cable core is fixedly installed on the inner wall of the charging cable, the water cooling pipe is fixedly connected inside the charging cable, the other end of the water cooling pipe is connected to the cooling water tank, and a charging gun is fixedly installed at one end of the charging cable.

[0011] Preferably, a cable hanging wheel is fixedly connected to the outer wall of the charging pile housing, and the charging cable is wound on the cable hanging wheel.

[0012] Preferably, the charging pile housing has multiple heat dissipation slots, a display screen and an emergency stop button are fixedly installed on the charging pile housing, a terminal block is rotatably installed on the charging pile housing, and the charging cable is slidably installed in the terminal block.

[0013] Preferably, a temperature monitoring module and an intelligent monitoring module are fixedly installed on the inner wall of the charging pile housing. The temperature monitoring module and the intelligent monitoring module are electrically connected to the charging pile control motherboard. Multiple concealed conduits are fixedly installed inside the charging pile housing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when the first guide rod rotates, it drives the rotating disk to rotate synchronously. When the rotating disk rotates, the airflow blown onto the surface of the rotating disk through the air duct will spread outwards along the arc surface, thereby increasing the airflow coverage of the heat dissipation fan on the heat spreader and further improving the heat dissipation efficiency of the heat spreader.

[0015] 2. In this invention, the airflow passing through the air duct will be guided by the spiral groove, so that the blown airflow is in a spiral shape, which can further increase the coverage of the airflow. After the airflow is blown into the air collecting hood, the airflow can bounce back in it and continue to blow towards the heat spreader plate due to the closed structure of the air collecting hood.

[0016] 3. In this invention, when the second ball slides along its inner wall, it is guided by a force. The force causes the second ball and the second guide rod to move in one of the random directions, up or down. This causes the direction of the rotating disk to change from facing the center of the heat spreader to facing outwards from the center. This changes the direction of the airflow after it blows onto the rotating disk and the direction of the airflow after it passes through the second vent hole and blows onto the heat spreader. This further increases the range of airflow covering the heat spreader and strengthens the different angles at which the airflow blows onto the heat spreader.

[0017] 4. In this invention, when the second guide rod, carrying the second ball, contacts the contact ball in the annular wave groove, the rotating disk will move the second sleeve away from the first sleeve, causing the second spring in the first sleeve to be stretched. At this time, the rotating disk will move closer to the heat spreader, and the blowing force will be relatively enhanced.

[0018] 5. In this invention, the dynamic swinging and multi-angle sweeping air-cooling mechanism of the charging pile can achieve efficient air supply and heat dissipation without dead angles throughout the entire area. While the cooling fan drives the rotating disk to rotate at high speed, the second ball slides along the annular wave groove on the inner wall of the air collector, causing the rotating disk to continuously swing up and down dynamically. Combined with the swirling airflow formed by the spiral groove on the inner wall of the air supply pipe and the guide flow on the arc surface of the rotating disk, the airflow forms a multi-angle dynamic sweep on the heat spreader plate, completely eliminating the air cooling blind zone. During the swinging process, the airflow diffusion angle and spray direction are continuously changed to fully cover all areas of the heat spreader plate. When the second ball touches the ball in the groove, the rotating disk will also move forward slightly to enhance the close-range blowing intensity. The swirling air supply and dynamic swinging sweeping work together to greatly improve the air cooling heat exchange efficiency, continuously and efficiently cool the water cooling circulation system, and ensure that the charging pile always maintains a stable heat dissipation state under high-power continuous charging conditions.

One end of the first spring 31 is fixedly connected to the outer wall of the fixing plate 30, and the other end of the first spring 31 is fixedly connected to the outer wall of the first sleeve 33.

[0024] The inner wall of the air duct 25 is provided with a spiral groove 29.

[0025] A cooling water tank 18 is fixedly installed on the inner wall of the fixed frame 16. A water supply pipe 24 is fixedly connected to the outer wall of the cooling water tank 18. A water pump 19 is fixedly installed on the cooling water tank 18. A water cooling pipe 17 is fixedly connected to the output end of the water pump 19. A heat dissipation water pipe 21 is fixedly connected to one end of the water cooling pipe 17. A heat dissipation plate 20 is fixedly installed on the outer wall of the heat dissipation water pipe 21. A plurality of evenly distributed first vent holes 22 are opened on the heat dissipation plate 20. A duct 23 is fixedly connected to the outer wall of the fixed frame 16. The other end of the duct 23 is fixedly connected to the inner wall of the charging pile housing 1.

[0026] Both ends of the heat dissipation water pipe 21 are fixedly connected to water cooling pipes 17. The inner wall of the charging pile housing 1 is fixedly installed with the charging pile control motherboard 14. Multiple circuit breakers 15 are fixedly installed on the inner wall of the charging pile housing 1. Charging cables 8 are fixedly connected to the circuit breakers 15. Cable cores 10 are fixedly installed on the inner wall of the charging cables 8. Water cooling pipes 17 are fixedly connected inside the charging cables 8. The other end of the water cooling pipes 17 is connected to the cooling water tank 18. A charging gun 9 is fixedly installed on one end of the charging cables 8.

[0027] A cable hanging wheel 4 is fixedly connected to the outer wall of the charging pile housing 1, and the charging cable 8 is wound on the cable hanging wheel 4.

[0028] Multiple heat dissipation slots 5 are provided on the charging pile housing 1. A display screen 2 and an emergency stop button 3 are fixedly installed on the charging pile housing 1. A terminal block 7 is rotatably installed on the charging pile housing 1, and the charging cable 8 is slidably installed in the terminal block 7.

[0029] A temperature monitoring module 12 and an intelligent monitoring module 13 are fixedly installed on the inner wall of the charging pile housing 1. The temperature monitoring module 12 and the intelligent monitoring module 13 are electrically connected to the charging pile control motherboard 14. Multiple concealed conduits 6 are fixedly installed inside the charging pile housing 1.

[0030] In this embodiment: When using this high-efficiency heat dissipation new energy charging pile, the user can remove the charging gun 9, pull the charging gun 9 and the charging cable 8, and align the end of the charging gun 9 with the car charging port for charging. Since the charging cable 8 is often dragged on the ground and easily causes wear, a hanging wheel 4 is provided to wind the excess charging cable 8 around the hanging wheel 4, so that the entire charging cable 8 is in a suspended state, reducing its friction contact with the ground.

[0031] During the charging process, the temperature monitoring module 12 and the intelligent monitoring module 13 installed inside the charging pile housing 1 will continuously monitor the temperature inside the charging pile housing 1 and the charging gun 9. When the temperature is abnormal, the temperature monitoring module 12 transmits an electrical signal to the charging pile control motherboard 14, and the charging pile control motherboard 14 controls the circuit breaker 15 to disconnect the circuit, quickly cutting off the overall passage of the charging pile housing 1 and providing fire safety protection.

[0032] Furthermore, the intelligent monitoring module 13 allows users to set up the charging pile through the display screen 2, supporting functions such as scheduled charging and querying the vehicle battery health index. The intelligent monitoring module 13 inside the charging pile housing 1 and the charging pile control motherboard 14 work together to achieve the above functions.

[0033] During the charging process, the charging pile control motherboard 14 will automatically start the water pump 19. After the water pump 19 starts, it will start to draw coolant from the cooling water tank 18 and deliver the coolant from the cooling water tank 18 to the water cooling pipe 17. Then, the coolant will be delivered through the water cooling pipe 17 through the charging cable 8 to perform heat exchange and heat dissipation on the cable core 10 inside the charging cable 8. The heat will be carried away by the flowing coolant. Then, the coolant will be delivered back to the cooling water tank 18 through the water cooling pipe 17 inside the charging cable 8 for a new round of circulation and heat dissipation, thus completing the basic water cooling operation of the charging cable 8.

[0034] To prevent the coolant temperature in the cooling water tank 18 from becoming too high after continuous high-power charging, after the water pump 19 delivers coolant into the water cooling pipe 17, one end of the water cooling pipe 17 is connected to the heat dissipation water pipe 21. The heat dissipation water pipe 21 is a copper pipe with multiple bends. Copper pipes have good thermal conductivity, and the heat dissipation plate 20 fixed outside the heat dissipation water pipe 21 is also made of copper plate. This allows for sufficient heat exchange and heat dissipation of the coolant delivered in the bend heat dissipation water pipe 21, further ensuring that the coolant can continuously circulate and dissipate heat for a long time.

[0035] While the charging pile control motherboard 14 starts the water pump 19, it also starts the cooling fan 27. After starting, the cooling fan 27 rotates at high speed with the rotating end. The cooling fan 27 blows the ambient temperature air from the outside through the heat sink 5 to the inner wall of the air duct 25. The airflow blows along the inner wall of the air duct 25 to the heat spreader 20, which is then cooled by air. The heat spreader 20 is provided with multiple first vent holes 22. The airflow passes through the first vent holes 22 and through the multiple heat spreaders 20, blowing the heat emitted by the heat spreader 20 into the air duct 23, and finally through the heat sink 5 to the outside, further ensuring the stability of the coolant during long-term use.

[0036] When the cooling fan 27 rotates, it drives the first guide rod 28 to rotate synchronously. When the first guide rod 28 rotates, it drives the rotating disk 36 to rotate synchronously. When the rotating disk 36 rotates, the airflow blown onto the surface of the rotating disk 36 through the air duct 25 will spread outwards along the arc surface 38. This can increase the airflow coverage of the cooling fan 27 on the heat spreader 20, further increasing the heat dissipation efficiency of the heat spreader 20, thereby ensuring the stability of the coolant during long-term use. In addition, the rotating disk 36 is provided with multiple second vent holes 37, through which airflow can be blown onto the heat spreader 20 at the center for heat dissipation without affecting the normal heat dissipation at the center.

[0037] The airflow passing through the air duct 25 is guided by the spiral groove 29, so that the blown airflow is in a spiral shape, which can further increase the coverage of the airflow. After the airflow is blown into the air collecting hood 26, the airflow can bounce back in it and continue to blow towards the heat spreader 20 due to the closed structure of the air collecting hood 26.

[0038] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-8 The rotating disk 36 has an arc surface 38 with an annular curved surface. A second guide rod 39 is fixedly connected to the rotating disk 36. A second ball bearing 42 is rotatably installed at one end of the second guide rod 39. An air collecting hood 26 is fixedly connected to one end of the air supply pipe 25. An annular wave groove 40 is opened on the inner wall of the air collecting hood 26. The second ball bearing 42 is slidably installed on the inner wall of the annular wave groove 40.

[0039] The inner wall of the annular wave groove 40 is fixedly connected with a plurality of evenly distributed abutment balls 41, which are configured as spherical blocks.

[0040] In this embodiment: when the rotating disk 36 rotates, it carries the second guide rod 39 to rotate synchronously. When the second guide rod 39 moves circumferentially, it carries the second ball bearing 42 at its end to slide along the inner wall of the annular wave groove 40. Since the inner contour of the annular wave groove 40 is set as a wave-shaped annular path, the second ball bearing 42 is guided by a force when it slides along its inner wall. This force causes the second ball bearing 42 and the second guide rod 39 to move in one of two random directions, up or down, causing them to move synchronously with the rotating disk 36. When the rotating disk 36 moves, it carries the second sleeve 34 and the first sleeve 33 to bend slightly along the first ball bearing 32, causing the direction in which the rotating disk 36 faces changes from directly facing... The position of the heat spreader 20 at the center changes to a position facing outwards from the center, which changes the direction of the airflow after it blows onto the rotating disk 36 and the direction of the airflow after it passes through the second vent 37 and blows onto the heat spreader 20. This further increases the range of airflow covering the heat spreader 20 and strengthens the different angles at which the airflow blows onto the heat spreader 20. When the second guide rod 39, carrying the second ball 42, contacts the abutting ball 41 in the annular wave groove 40, the rotating disk 36, carrying the second sleeve 34, moves away from the first sleeve 33, causing the second spring 35 in the first sleeve 33 to be stretched. At this time, the rotating disk 36 moves closer to the heat spreader 20, and the blowing force is relatively enhanced.
