Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and more specifically to a heat dissipation structure of a charging pile for a new energy vehicle. Background Art

[0002] With the shortage of oil resources and the development of battery technology, a new generation of energy-saving and environmentally friendly vehicles represented by electric vehicles has become an inevitable trend in the development of the automobile industry. With the development and popularization of electric vehicles, electric vehicle charging piles, as an indispensable supporting facility for electric vehicles, are increasingly in demand. The function of the charging pile is similar to that of a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. If the charging pile uses low-power charging, it will take a long time to charge. If you want to charge faster, you need to use high-power charging. Long-term operation or high-power operation will cause heat generation. Therefore, both need to use active heat dissipation to ensure the safety of the device. However, the existing heat dissipation structure of the new energy charging pile still has the disadvantage of being simple in structure during use. It only uses a heat dissipation fan to speed up the air circulation of the main parts inside the device to dissipate heat. When the external air temperature is high, the heat dissipation effect is not good. In addition, the main parts inside the device are directly connected to the outside. Once there is strong wind or heavy rain, there is a possibility of water or dust entering the inside of the device, which is easy to cause damage to the internal structure of the device.

[0003] Therefore, it is necessary to propose a heat dissipation structure of a charging pile for new energy vehicles to solve the above problems. Utility Model Content

Once encountering strong winds or heavy rain, there is a possibility of water or dust entering the inside of the device, which easily leads to damage to the internal structure of the device. The utility model provides a heat dissipation structure of a charging pile for new energy vehicles.

[0030] In this embodiment, the water inside the water tank 11 can be introduced into the heat dissipation pipe 5 through the matching of the water pump 7, and the water inside the heat dissipation pipe 5 can be introduced into the cooling pipe 9 through the connecting pipe 10. The water flowing inside the cooling pipe 9 can be cooled by ventilation through the through hole 12, and the precipitation can be discharged into the water tank 11 through the drainage pipe 22. In this way, the temperature of the object in contact with the heat dissipation plate 3 can be diverted by the flowing water, thereby achieving the purpose of heat dissipation.

[0031] Example 2

[0032] See also Figure 2 This embodiment is further optimized on the basis of the embodiment 1. Specifically, the heat dissipation pipe 5 is arranged horizontally in an S shape, and the cooling pipe 9 is arranged in an S-shaped ring shape. The heat dissipation pipe 5, the cooling pipe 9, the connecting pipe 10 and the drain pipe 22 are all made of metal copper material. The metal copper material has a good thermal conductivity. The use of copper material can make its heat dissipation efficiency higher.

[0033] Specifically, a control switch 13 is fixedly connected to one side of the upper end of the charging pile 1 , and a charging gun 14 is symmetrically fixedly connected to the front side of the upper end of the charging pile 1 .

[0034] Specifically, a plurality of heat sinks 15 made of metal aluminum are fixedly connected to the inner side of the cooling tube 9 . The ends of the plurality of heat sinks 15 that are close to each other penetrate the charging pile 1 and are located in the through hole 12 . The air flowing through the through hole 12 can indirectly cool the cooling tube 9 via the heat sink 15 .

[0035] Specifically, a fixing frame 16 is fixedly connected to one end of the inner side of the through hole 12 , a heat dissipation fan 17 is fixedly installed on the inner side of the fixing frame 16 , and mesh plates 18 are fixedly connected to both end openings of the through hole 12 .

[0036] In this embodiment, the heat sink 15 and the heat dissipation fan 17 can increase the contact area between the cooling tube 9 and the flowing air while accelerating the air flow rate inside the through hole 12, thereby achieving a better cooling effect and a faster cooling speed. During the entire cooling process, the main body 4 does not come into contact with the outside world, thereby preventing water or dust from coming into contact with the main body 4.

[0037] Example 3

[0038] See also Figure 1 and 3 This embodiment is optimized as follows based on Example 1 or Example 2. Specifically, a box door 19 is movably installed on one side of the upper end of the charging pile 1, and the box door 19 is adapted to the cavity 2.

[0039] Specifically, a micro low-pressure air pump 20 is fixedly installed on the upper side of the rear end of the cavity 2, and the inner side of the micro low-pressure air pump 20 includes a drying device.

[0040] In this embodiment, the main body 4 can be inspected and maintained when necessary through the box door 19, and the box door 19 is usually in a normally closed state. Air can be injected into the cavity 2 through the micro low-pressure air pump 20, and the injected air can be dried by the drying device inside the micro low-pressure air pump 20. The air pressure inside the cavity 2 can be made higher than that outside by air injection, so as to prevent external humid air from entering the cavity 2. Air can flow out through the door gap of the box door 19, and dry air can be pumped into the cavity 2 with the micro low-pressure air pump 20, so that the inside of the cavity 2 can always be in a dry state.

[0041] In summary, the utility model, when in use, can adapt the water pump 6 and the water pump 7, so that the water inside the water tank 11 can be introduced into the heat dissipation pipe 5, and the water inside the heat dissipation pipe 5 can be introduced into the cooling pipe 9 through the connecting pipe 10. The water flowing inside the cooling pipe 9 can be cooled by ventilation through the through hole 12, and the precipitation can be discharged into the water tank 11 through the drainage pipe 22. In this way, the circulating flow can guide the temperature of the object in contact with the heat dissipation plate 3 through the flowing water, so that the main body 4 and the inside of the cavity 2 can be cooled. The heat sink 15 and the heat dissipation fan 17 can speed up the air flow speed inside the through hole 12 while making the contact area between the cooling pipe 9 and the flowing air larger, so that the cooling effect is better and the cooling speed is faster. During the whole cooling process, the main body 4 is not in contact with the outside world. The main body 4 can be kept dry by the miniature low-pressure air pump 20, and the air pressure inside the cavity 2 can be made higher than that outside by the air injection, so as to prevent the external humid air from entering the cavity 2, and the air can flow out through the gap of the door 19, and the micro-low-pressure air pump 20 can be used to pump dry air into the cavity 2, so as to keep the interior of the cavity 2 in a dry state at all times, so as to prevent the humid air from entering the main body 4 and damaging it.
