Description

Technical Field

[0001] The utility model relates to the technical field of charging and cooling, and in particular to a new energy charging box with a double-liquid thermal management cooling system. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and new vehicle power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] Pure electric vehicles need to be connected to new energy cables when charging. In order to increase the charging speed of pure electric vehicles, they need to be equipped with charging boxes for charging. The power during charging is very high, so a lot of heat will be generated during the charging process. When the cable is overheated, the insulation skin on the outside is prone to aging and cracking. Therefore, it is necessary to design a charging solution through liquid cooling. The prior art (Announcement No.: CN116018656A, Announcement Date: 2023.04.25) discloses a liquid-cooled charging cable for new energy vehicles. A cooling pipe and a return pipe are provided in the cable to achieve liquid cooling of the power core. However, when the fluorinated liquid in the cooling pipe cools the power core, it is equipped with an insulating layer to wrap the core conductor, resulting in poor heat dissipation effect. At present, the fluorinated liquid itself has insulating properties (for example, pure water is not conductive), and the insulating fluorinated liquid can be directly transported to the core conductor for heat dissipation, and there will be no leakage. Moreover, this method can further improve the cooling effect of the cable, and there is no need to equip the cooling pipe and the return pipe separately, thereby effectively reducing the preparation cost of the cable.

[0004] To this end, the utility model patent with application number 2024210518251 records a cable that uses air cooling and liquid cooling for cooling. A conductive gap is set to achieve stable transmission of air or insulating fluorinated liquid between the wire core and the insulating sleeve, thereby effectively reducing the temperature of the cable when the new energy vehicle is charging. However, there is currently no matching charging box. Therefore, the utility model provides a new energy charging box with a dual-liquid thermal management cooling system to solve this technical problem. Utility Model Content

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1-8 As shown, a new energy charging box with a dual-liquid thermal management cooling system of the utility model includes a pile body 1, a cable 2 is connected to the pile body 1, a charging gun 3 is connected to the outer end of the cable 2, a gun seat 4 is fixedly installed on the outer side of the pile body 1, and the charging gun 3 is detachably connected to the gun seat 4;

[0043] The cable 2 comprises an outer protective tube 2.1, a liquid inlet tube 2.2 and two liquid cooling cables 2.3, and the liquid inlet tube 2.2 and the two liquid cooling cables 2.3 are both installed in the outer protective tube 2.1;

[0044] Two gun needles 5 are fixedly installed in the charging gun 3, and a needle seat 6 is formed at the tail end of the gun needle 5. Two liquid cooling cables 2.3 are sealed and connected to the needle seats 6 of the two gun needles 5 one by one. The outer end of the liquid inlet pipe 2.2 is connected to the two needle seats 6, and the liquid inlet pipe 2.2 supplies liquid to the liquid cooling cable 2.3 through the needle seat 6;

[0045] A condensation box 7 is fixedly installed in the pile body 1, and a liquid outlet pipe 8 is fixedly installed at the inner end of the two liquid cooling cables 2.3. The liquid outlet pipe 8 extends into the condensation box 7 for cooling and then flows back to the liquid inlet pipe 2.2 from the condensation box 7;

[0046] The principle is as follows: the utility model utilizes the liquid inlet pipe 2.2 to infuse liquid into the two liquid-cooling cables 2.3, and the liquid in the liquid-cooling cable 2.3 is transported to the condensation box 7 through the liquid outlet pipe 8 for cooling. Since the condensation box 7 can store fluorinated liquid, the fluorinated liquid in the liquid inlet pipe 2.2 and the two liquid-cooling cables 2.3 can be quickly cooled, thereby achieving the technical effect of quickly reducing the temperature of the gun needle 5, ensuring the stability of the new energy vehicle during charging, preventing the cable 2 from overheating, and effectively reducing safety hazards.

[0047] The charging box of the utility model can withstand high-power use of 800A 1500V and has high stability during long-term high-power charging, thereby enhancing the safety of new energy vehicles during charging.

[0048] Furthermore: a water injection port 9 and a safety valve 10 are provided on the side of the condensation box 7. The condensation box 7 is filled with fluorinated liquid through the water injection port 9, and the liquid outlet pipe 8 extends into the fluorinated liquid in the condensation box 7 for rapid cooling; the fluorinated liquid can be injected into the condensation box 7 through the water injection port 9, and a water level gauge is provided on the outside of the pile body 1, so that the remaining fluorinated liquid in the condensation box 7 can be visually seen, thereby achieving the effect of quickly replenishing the fluorinated liquid. The setting of the safety valve 10 can prevent the difference between the internal and external air pressures of the condensation box 7 and be too large, thereby providing the condensation box 7 with an explosion-proof effect.

[0049] Furthermore: the liquid transported in the liquid inlet pipe 2.2, the liquid outlet pipe 8 and the liquid cooling cable 2.3 is fluorinated liquid, and a curved and coiled condenser tube is arranged in the condenser box 7, and the cooling liquid is transported in the condenser tube; the fluorinated liquid can quickly vaporize and absorb heat, and can also quickly condense into liquid for flow. At the same time, it has the characteristic of being non-conductive, and can be applied to the liquid cooling cable 2.3 to achieve rapid cooling, ensuring that the temperature of the cable 2 will not be too high when the new energy vehicle is charging. The cooling liquid can flow into the curved and coiled condenser tube from the bottom of the condenser box 7, thereby quickly reducing the temperature of the condenser box 7.

[0050] Furthermore: a widening box 11 is formed at the top of the pile body 1, and a T-shaped structure is formed between the widening box 11 and the pile body 1, and the inner end of the cable 2 leads to the bottom side of the widening box 11, so that the top end of the cable 2 can be vertically transported into the pile body 1.

[0051] Furthermore: an anti-pull sensor 12 is fixedly installed in the widened box 11, and the inner end of the cable 2 is installed on the bottom side of the anti-pull sensor 12; pulling the cable 2 during charging will trigger the anti-pull sensor 12, thereby automatically powering off the cable 2 and stopping charging, which can avoid the situation where the charging gun 3 becomes loose due to pulling the cable 2 during charging and avoid malfunctions.

[0052] Furthermore: a 90° forward and reverse rotation limiter 13 is fixedly installed on the anti-pull sensor 12; it can effectively limit the rotation angle of the cable 2 to avoid excessive rotation causing the line connection to break; at the same time, the cable 2 is limited when it rotates 90°, and the cable 2 can rotate, allowing the user to move and use the charging gun 3 more conveniently.

[0053] Further: the forward and reverse rotation 90° limiter 13 includes a bottom ring 13.1 and a top ring 13.2, the top side edge of the bottom ring 13.1 is formed with a first cam edge 13.3, the bottom side edge of the top ring 13.2 is formed with a second cam edge 13.4, the second cam edge 13.4 is against the first cam edge 13.3, the bottom ring 13.1 is fixedly mounted on the anti-pull sensor 12, and the inner end of the cable 2 is fixedly mounted in the top ring 13.2; so that it can be rotated 90° in the forward direction or 90° in the negative direction, the cable 2 will be more convenient to use.

[0054] Furthermore: a pressure sensor and a tension sensor are provided in the anti-pull sensor 12, and the two sensors are used to accurately determine whether the cable 2 is pulled during charging. When the cable 2 is pulled, the power can be cut off in time, thereby effectively preventing leakage and improving safety.

[0055] Furthermore: a collision sensor 14 is fixedly installed at the tail end of the charging gun 3; when the cable 2 is pulled or the charging gun 3 collides during charging, the collision sensor 14 will be triggered, causing the cable 2 to automatically cut off power and stop charging, thereby effectively preventing the cable 2 and the charging gun 3 from malfunctioning.

[0056] Furthermore: a vacuum tube 15 is also installed in the outer protective tube 2.1, a vacuum hole 16 is formed in the middle of the gun needle 5, and the outer end of the vacuum tube 15 is connected to the vacuum hole 16; the vacuum tube 15 can be adsorbed to the charging end of the new energy vehicle, and a stable connection can be achieved by plugging and vacuum adsorption.

[0057] Furthermore, a vacuum pump 17 is fixedly installed in the pile body 1, and the inner end of the vacuum tube 15 is connected to the vacuum pump 17; the vacuum pump 17 can be used to perform vacuum adsorption to achieve a stable connection.

[0058] Furthermore: the gun needle 5, the vacuum hole 16, and the vacuum tube 15 form an air-cooling heat dissipation channel 18 during charging; while vacuum adsorption occurs, part of the airflow will pass through the gap between the gun needle 5 and the charging end of the new energy vehicle, thereby forming an air-cooling heat dissipation channel 18, which can accelerate the heat dissipation effect.

[0059] Furthermore: a shunt 19 is fixedly installed in the pile body 1, a first grounding wire 20 is installed in the vacuum tube 15, the inner end of the first grounding wire 20 is connected to the shunt 19, a leakage monitoring line 21 is arranged on the side of the shunt 19, and the shunt 19 is also electrically connected to a second grounding wire 22 and a third grounding wire 28, the second grounding wire 22 is connected to the inner side of the pile body 1 for grounding, and the third grounding wire 28 is directly connected to the ground; the shunt 19 can be used for grounding to avoid leakage during vacuum adsorption, thereby effectively preventing electric shock and having higher safety.

[0060] The leakage monitoring line 21 is two electric wires drawn out from the shunt 19, which are used to monitor whether there is leakage, thereby effectively preventing electric shock, and the use safety is high.

[0061] Furthermore: the cable 2 and the charging gun 3 are fixedly installed with luminous optical fibers; when charging, the luminous optical fibers can be turned on to prompt the user, thereby quickly determining whether the new energy vehicle is in a charging state.

[0062] Furthermore: a control area 23 is fixedly installed on the outer wall of the pile body 1. When in use, the control area 23 will be connected to the license plate entry and brake linkage system. Charging and payment can be completed by setting a touch screen 23.1 and a code scanning, card swiping, face swiping, and palm swiping area 23.2 on the control area 23. A stop button 23.3 is fixedly installed on the pile body 1. The stop button 23.3 is electrically connected to the charging gun 3 for pausing or completely stopping charging, which is convenient for actual use. The license plate can be scanned and entered through a camera and linked with the brake system, eliminating the step of manual entry in the traditional charging box, making charging more convenient.

[0063] Furthermore: a liquid-cooled temperature sensor 27 is fixedly installed at one end of the liquid outlet pipe 8 extending into the condensation tank 7, and a gun needle temperature sensor 24 is fixedly installed at the inner end of the gun needle 5; the gun needle temperature sensor 24 is arranged at the connection between the gun needle 5 and the cable 2, and can monitor the temperature of the gun needle 5 in real time. It can send a signal when the temperature of the gun needle 5 is too high, and it will stop working instantly when it is overheated; the liquid-cooled temperature sensor 27 is used to monitor the temperature of the condensate when it returns to the condensation tank 7. If the temperature is too high, a signal warning will be issued to stop the charging gun 3 from working, thereby forming multiple protections with the gun needle temperature sensor 24.

[0064] Furthermore: a radar sensor switch 25 and a touch sensor switch 26 are fixedly installed in the charging gun 3; the two sensors can be used to simultaneously determine whether the charging gun 3 is being held. When one of the sensors is triggered, it can be determined that the charging gun is being held. At this time, the power is off, avoiding electric shock caused by illegal operation by the user, which is safer.

[0065] The radar sensing switch 25 is used for remote sensing. When the user is 70 cm close to the charging gun during car charging, an alarm is issued, and the power is disconnected at 40 cm. The touch sensing switch 26 is used for double protection. If the radar sensing switch 25 fails to respond in time and the user touches the gun body before charging is completed, the charging gun 3 will be instantly powered off, which can form multiple protections with the radar sensing switch 25.

[0066] Furthermore: a support ring 29 is sleeved on the gun needle, and the support ring 29 is fixedly installed in the needle seat. The support ring 29 is made of a low thermal conductivity alloy, which can effectively protect the gun body and prevent the gun needle from overheating instantly, causing the charging gun to deform.

[0067] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
