Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of charging pile, concretely relates to a liquid cooling terminal charging pile. BACKGROUND

[0002] With the popularity of electric vehicles, charging piles as an important supporting facility of electric vehicles, its performance and stability are concerned. The liquid cooling terminal charging pile is a new type of charging pile, compared with the traditional air-cooled charging pile, it adopts liquid cooling technology to efficiently dissipate the heat generated during charging, which can effectively improve the power density and charging efficiency of the charging pile, reduce the failure of the charging pile caused by overheating, and prolong the service life of the charging pile.

[0003] However, the existing traditional liquid cooling terminal charging pile has many drawbacks. First, in terms of structural design, the internal layout of some traditional liquid cooling terminal charging piles is not reasonable. For example, the size of the front door plate does not match the main body of the charging pile, which makes installation and maintenance inconvenient, and the sealing performance is poor, which makes it easy for dust, water vapor and other impurities to enter the internal charging pile, affecting the normal work of the internal electronic components. At the same time, the distribution of internal functional modules is not scientifically planned, which makes the line connection complex and increases the difficulty of troubleshooting and maintenance. Secondly, in terms of heat dissipation, although the liquid cooling technology is adopted, the design of the heat dissipation channel has defects. The position of the liquid cooling unit of some traditional liquid cooling terminal charging piles does not match the ventilation opening, which leads to low heat dissipation efficiency. The liquid cooling unit cannot fully utilize the cold air introduced by the ventilation opening for heat exchange, so that the internal temperature of the charging pile is still too high during long-time high-power charging, which affects the performance and life of the electronic components. Moreover, the heat insulation and heat dissipation measures between different functional areas inside are insufficient, such as the heat generated by high-voltage direct-current contactors, fuses and other heat-generating components, which can easily be transmitted to other modules, interfering with the normal operation of other modules. SUMMARY

[0004] Therefore, the utility model provides a liquid cooling terminal charging pile, which solves the problem of unreasonable internal layout of the traditional liquid cooling terminal charging pile and improves the work efficiency.

[0005] The utility model is realized as follows:

[0006] The utility model provides a liquid cooling terminal charging pile, which includes a charging pile, wherein the front face of the charging pile is provided with a front door plate, the charging pile is provided with a containing space corresponding to the position of the front door plate, the containing space includes an upper through slot and a lower through slot, the inner side of the front door plate is sequentially provided with a display screen, a vehicle controller unit and a fan from top to bottom, the top of the charging pile is provided with an antenna and a lifting ring, the lower through slot is provided with a liquid cooling unit, and the side face of the charging pile is provided with a gun seat and a gun line outlet for passing out the gun line.

[0007] The master control module is electrically connected with a card swiping display screen, a TCU (vehicle controller unit) and a fan.

[0008] On the basis of the above technical scheme, the liquid-cooled terminal charging pile can be further improved as follows:

[0009] The front door plate is rectangular, and the size of the rectangle is equal to the size of the front of the charging pile.

[0010] The size matching design ensures that the front door plate is closely attached to the main body of the charging pile, enhances the sealing property of the charging pile, prevents impurities such as dust and water vapor from entering the interior, protects the internal electronic components, prolongs the service life of the equipment, and also makes the appearance more beautiful and neat.

[0011] Further, the upper through slot is sequentially provided with a master control module, a water immersion sensor, a high-voltage direct-current contactor, a fuse, a shunt and a copper busbar from top to bottom, a wire slot is arranged between the master control module and the water immersion sensor, and a partition plate is arranged between the water immersion sensor and the high-voltage direct-current contactor, the fuse, the shunt and the copper busbar.

[0012] The orderly element layout facilitates line connection and fault troubleshooting, the partition plate effectively prevents electromagnetic interference and heat transfer between different modules, ensures stable work of each module in a relatively independent environment, and improves the stability and reliability of the charging pile operation.

[0013] Further, the display screen, the vehicle controller unit and the fan in the closed state of the front door plate correspond to the upper through slot.

[0014] The corresponding layout minimizes the line connection, reduces signal transmission loss, and facilitates equipment installation and maintenance. When the display screen, the vehicle controller unit or the fan needs to be repaired, it can be directly operated by opening the front door plate, thereby improving the maintenance efficiency.

[0015] Further, the left and right sides of the charging pile are both provided with ventilation openings.

[0016] The beneficial effects of the above improvement scheme are that the ventilation opening provides good ventilation conditions for the charging pile, cooperates with the liquid cooling unit to form an efficient heat dissipation system, ensures that the heat generated by the charging pile during operation can be dissipated in time, ensures that the internal electronic components work in a suitable temperature environment, and improves the performance and service life of the equipment.

[0017] Further, the ventilation opening position corresponds to the position of the liquid cooling unit in the lower through groove.

[0018] The liquid cooling unit mainly consists of a cooling liquid circulating pump, a heat exchanger, a cooling liquid storage tank, connecting pipelines, and various sensors.

[0019] Cooling liquid circulating pump: It is the power source of the entire liquid cooling system, which drives the cooling liquid to circulate in the entire liquid cooling circuit. Through mechanical power, the cooling liquid is pumped out from the cooling liquid storage tank and then pressurized to be delivered to the parts inside the charging pile that need to be cooled, ensuring that the cooling liquid can continuously absorb heat and carry it away.

[0020] Heat exchanger: It is one of the core components of the liquid cooling unit, which is a key device for heat exchange. The heat exchanger adopts a high-efficiency heat exchange structure, such as a plate heat exchanger or a tube heat exchanger. When the charging pile is working, the high-temperature cooling liquid that has absorbed the heat of the internal components of the charging pile flows into the heat exchanger, where it exchanges heat with the cold air introduced from the ventilation opening.

[0021] Cooling liquid storage tank: used for storing cooling liquid to provide cooling liquid reserves for the entire liquid cooling system. It not only ensures the continuous supply of cooling liquid, but also plays a role in buffering and stabilizing the pressure of the cooling liquid. At the same time, the cooling liquid storage tank is usually equipped with a liquid level sensor to monitor the liquid level of the cooling liquid in real time, and when the liquid level is too low, it will send out an alarm to remind the staff to supplement the cooling liquid.

[0022] Connecting pipeline: responsible for connecting various components into a complete liquid cooling circuit to ensure smooth flow of cooling liquid.

[0023] Various sensors: including temperature sensors, pressure sensors, etc.

[0024] The beneficial effects of the above improvement scheme are that the precise corresponding position enables the liquid cooling unit to fully utilize the cold air introduced by the ventilation opening for heat exchange, greatly improving the heat dissipation efficiency, effectively reducing the internal temperature of the charging pile even during high-power charging, and ensuring stable operation of the equipment.

[0025] Further, a partition is arranged between the upper through groove and the lower through groove, the partition is provided with a through hole, and the through hole corresponds to the projected position of the shunt and the copper busbar.

[0026] The beneficial effects of the improved scheme are that the partition prevents electromagnetic interference and disordered heat transfer between the upper through groove and the lower through groove, the through hole design enables the heat generated by the shunt and the copper bus to be transferred to the lower through groove for unified heat dissipation by the liquid cooling unit, the overall heat dissipation and efficiency are improved, and the heat dissipation performance of the charging pile is optimized.

[0027] Further, the front door plate is hinged to the front face of the charging pile.

[0028] Further, the display screen is specifically a card swiping display screen.

[0029] Further, the two lifting rings are respectively located at left and right sides of the top of the charging pile.

[0030] The beneficial effects of the improved scheme are that the symmetrical design of the two lifting rings can ensure uniform stress during the carrying and installation of the charging pile, facilitate the operation of the staff, ensure the safety of the charging pile during the carrying process, and avoid equipment damage caused by uneven stress.

[0031] Compared with the prior art, the liquid-cooled terminal charging pile has the following beneficial effects:

[0032] First, in terms of structural design, reasonable layout brings many conveniences. The design that the front door plate is matched in size with the front face of the charging pile and is hinged makes installation and maintenance simple and easy. Maintenance personnel can conveniently open the front door plate to check and replace internal elements, greatly shortening the maintenance time and improving the work efficiency. At the same time, the closely fitted front door plate improves the sealing property of the charging pile, reduces the erosion of external impurities on internal elements, reduces the probability of failure, and prolongs the service life of the charging pile. The reasonable distribution of internal functional modules makes the line connection more simple and clear, reduces line crossing and winding, reduces the risk of failure caused by line problems, and is convenient for troubleshooting and maintenance;

[0033] Secondly, in terms of heat dissipation performance, the utility model has a significant improvement. The corresponding design of the optimized liquid cooling unit and the ventilation opening greatly improves the heat dissipation efficiency. The liquid cooling unit can fully utilize the cold air introduced by the ventilation opening for heat exchange, quickly and effectively reducing the temperature inside the charging pile. Even in the case of long-time high-power charging, the internal elements of the charging pile can be kept within the appropriate working temperature range, thereby improving the performance stability and service life of the electronic elements.

[0034] In addition, the intelligent control has obvious advantages. The electrical connection of the main control module and each functional module realizes comprehensive monitoring and intelligent management of the charging pile. Through real-time monitoring of the running state and power consumption of the charging pile, the operator can timely understand the working condition of the charging pile, discover potential fault hidden dangers in advance, and perform preventive maintenance. At the same time, users can conveniently operate through the card swiping display screen, such as starting charging by swiping a card, inquiring about charging progress, and paying fees. In addition, remote reservation, real-time inquiry and other functions can be realized through the remote communication function, providing users with more convenient charging service experience and improving user satisfaction.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0043] As Figures 1-4The utility model provides a kind of liquid cooling terminal charging pile, and the embodiment of the utility model is shown, in this embodiment, including charging pile 10, wherein, the front of charging pile 10 is provided with front door plate 11, charging pile 10 is opened with accommodating space corresponding to the position of front door plate 11, accommodating space includes upper through slot 13 and lower through slot 18, the inside of front door plate 11 is sequentially provided with display screen 12, vehicle controller unit 14 and fan 15 from top to bottom, antenna 16 and lifting ring 17 are installed on the top of charging pile 10, lower through slot 18 position is provided with liquid cooling unit, the side of charging pile 10 is provided with gun seat 30 and the gun line outlet for passing out gun.

[0045] Further, in the above technical solution, the upper through slot 13 is sequentially provided with a main control module 131, a water immersion sensor 132, a high-voltage direct-current contactor 133, a fuse 134, a shunt 135, and a copper busbar 136 from top to bottom. A wire slot is provided between the main control module 131 and the water immersion sensor 132. A partition is provided between the water immersion sensor 132 and the high-voltage direct-current contactor 133, the fuse 134, the shunt 135, and the copper busbar 136.

[0046] Further, in the above technical solution, the display screen 12, the vehicle controller unit 14, and the fan 15 in the closed state of the front door plate 11 correspond to the upper through slot 13.

[0047] Further, in the above technical solution, the left and right sides of the charging pile 10 are both provided with ventilation openings.

[0048] Further, in the above technical solution, the ventilation openings correspond to the positions of the liquid cooling units in the lower through slots 18.

[0049] The cooperative working process of the liquid cooling unit and the ventilation opening is as follows:

[0050] When the charging pile starts to work, the internal electronic components such as high-voltage direct-current contactors and copper busbars will generate a large amount of heat. At this time, the cooling liquid circulating pump starts to pump the cooling liquid in the cooling liquid storage tank into the connecting pipeline. The cooling liquid flows in the pipeline, passes through the parts that need to be cooled, absorbs the heat generated by these parts, and thus the temperature rises.

[0051] The heated cooling liquid flows into the heat exchanger, and at this time, the cold air introduced from the left and right air vents of the charging pile also enters the heat exchanger. Inside the heat exchanger, the high-temperature cooling liquid and the cold air are subjected to sufficient heat exchange. Due to the special structural design of the heat exchanger, the two can achieve efficient heat transfer without mixing. The heat of the high-temperature cooling liquid is transferred to the cold air, the cooling liquid temperature is lowered, and it flows back to the cooling liquid storage tank, ready for the next cycle. The cold air that has absorbed heat is discharged outside the charging pile through the air vent.

[0052] Further, in the above technical solution, a partition plate is arranged between the upper through slot 13 and the lower through slot 18, and the partition plate is provided with a through hole corresponding to the projection position of the shunt 135 and the copper bar 136.

[0053] Further, in the above technical solution, the front door plate 11 is hinged to the front of the charging pile 10.

[0054] Further, in the above technical solution, the display screen 12 is specifically a card swiping display screen.

[0055] Further, in the above technical solution, the lifting ring 17 has two, and the two lifting rings 17 are respectively located at the left and right sides of the top of the charging pile 10.

[0056] Specifically, the principle of the liquid-cooled terminal charging pile of the utility model is based on reasonable structural design, efficient heat dissipation system and intelligent control module:

[0057] In the structural design, the charging pile is a cuboid as a whole, and the front door plate is rectangular and has the same size as the front of the charging pile. This design ensures that the front door plate is closely attached to the main body of the charging pile, improves the sealing performance, and effectively prevents dust and water vapor from entering. The front door plate is hinged to the front of the charging pile, which facilitates the installation, maintenance and repair of internal components. The display screen, vehicle controller unit and fan are arranged in the front door plate from top to bottom, corresponding to the upper through slot in the closed state, and the layout is reasonable, facilitating line connection and signal transmission.

[0058] The element layout in the upper through slot is also carefully designed. The main control module, water immersion sensor, high-voltage DC contactor, fuse, shunt and copper bar are arranged from top to bottom, and wire slots are arranged between the main control module and the water immersion sensor, and between the water immersion sensor and the high-voltage DC contactor and other elements.

[0059] The liquid cooling unit is arranged at the position of the lower through groove, and the ventilation openings are arranged on the left and right sides of the charging pile, and the positions of the ventilation openings correspond to the positions of the liquid cooling units in the lower through groove. The heat dissipation principle is that when the charging pile works, the cooling liquid in the liquid cooling unit flows under the action of the circulating pump, absorbs the heat generated by the internal elements of the charging pile, and then transfers the heat to the cold air entering from the ventilation opening through the heat exchanger. The cold air is discharged from the charging pile after absorbing the heat, thereby realizing the heat dissipation of the internal part of the charging pile. The partition plate arranged between the upper through groove and the lower through groove has through holes corresponding to the projection positions of the shunt and the copper bus bar, and such a design can make part of the heat generated in the upper through groove be transmitted to the lower through groove through the through holes, and the unified heat dissipation is realized by the liquid cooling unit, thereby improving the comprehensiveness and efficiency of heat dissipation.

[0060] In terms of intelligent control, the main control module is electrically connected with the card swiping display screen, the vehicle controller unit and the fan. The main control module serves as the core control unit of the entire charging pile and is responsible for collecting and processing data of various sensors such as temperature sensors and current sensors, and monitoring the running state of the charging pile in real time. According to the monitoring data, the main control module can control the rotating speed of the fan and adjust the ventilation volume to adapt to different heat dissipation requirements. At the same time, it can also communicate with the card swiping display screen to show the working state of the charging pile, charging cost and other information to the user, receive the operation instructions of the user, and realize the man-machine interaction function. The vehicle controller unit is mainly responsible for communicating with the electric vehicle, coordinating the charging process and ensuring the safety and stability of the charging.
