Description

Technical Field

[0001] This invention belongs to the field of charging pile technology, and in particular relates to a car charging pile with a high-efficiency heat dissipation mechanism. Background Technology

[0002] Car charging stations are mainly used to charge electric vehicles. As the number of electric vehicles increases, the number of charging stations is also gradually increasing. With the development of technology, the power of charging stations is also increasing to charge cars faster. During the charging process, the heat generated by the increased power is also increasing, which makes it necessary for charging stations to be equipped with efficient heat dissipation structures.

[0003] Nowadays, high-power charging piles often use liquid cooling to dissipate heat, ensuring that the charging gun and cables are within a suitable temperature range. When used in low-temperature environments such as winter, the coolant becomes viscous due to the temperature drop, which not only hinders flow but also affects the charging power increase rate of the charging pile, thus affecting the overall charging efficiency of electric vehicles. Summary of the Invention

[0004] The purpose of this invention is to provide a car charging station with a high-efficiency heat dissipation mechanism to solve the problem that the coolant becomes viscous in low-temperature environments, which affects the coolant circulation effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a car charging pile with a high-efficiency heat dissipation mechanism, comprising a cabinet, a cable on one side of the cabinet, a charging gun at one end of the cable, and further comprising:

[0006] A heat dissipation assembly, comprising finned tubes disposed inside the cabinet, which are used to cool the coolant flowing through the cabinet.

[0007] A cooling assembly includes a cooling sleeve disposed on the outer wall of the charging terminals inside the charging gun, wherein a coolant flows inside the cooling sleeve to cool the charging terminals inside the charging gun.

[0016] The push rod is slidably installed in the sliding groove inside the mounting base, and a lever is rotatably installed at one end of the push rod. A stop block corresponding to the lever is also provided at one end of the push rod. The movement of the push rod drives the lever to move the rotating frame, thereby causing the ball core to rotate.

[0017] As a further description of the above technical solution:

The movable seat has movable modules on both sides, and one side of the movable seat has an extrusion groove corresponding to the push rod. The push rod is pushed by the protrusion inside the extrusion groove, which causes the ball core to rotate, thereby connecting the movable seat with the fin tube.

[0020] As a further description of the above technical solution:

[0021] The heat dissipation assembly further includes an input pipe, which is installed at the bottom of the movable base and is connected to the internal through hole of the movable base.

[0025] Telescopic tubes are installed on the upper and lower sides of the support base, and multiple telescopic tubes are arranged linearly.

[0029] The extrusion block is disposed inside the fixed sleeve, and the bottom end of the extrusion block is in contact with the outer wall of the cooling sleeve. The extrusion block extrudes the cooling sleeve to tighten it inward.

[0030] The bolts are rotatably disposed in the through hole on the outer wall of the fixed sleeve, and the bolts are threadedly connected to the extrusion block through the threaded hole provided on the top surface of the extrusion block, and multiple bolts are arranged linearly.

[0034] As a further description of the above technical solution:

[0035] The exhaust assembly further includes a grid plate, which is installed inside the mounting housing and collects air bubbles inside the coolant.

[0036] A float is disposed inside the exhaust shell, and the internal through hole of the exhaust shell corresponds to the float. The float blocks the internal through hole of the exhaust shell to control the communication state of the exhaust shell.

[0037] As a further description of the above technical solution:

[0038] The exhaust assembly further includes a sealing ring, which is installed on the outer wall of the float;

[0039] A fixing rod is installed on the top of the float, and a limiting plate is installed on the top of the fixing rod, and the limiting plate is slidably disposed in the through hole of the exhaust shell.

[0040] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0041] 1. In this invention, by setting up a heat dissipation component, this design enables the use of charging piles in cold environments such as winter. By changing the position of the movable base, the entry point of the coolant can be altered, and the flow path length of the coolant inside the finned tube can be changed. This alters the amount of heat dissipated by the finned tube to the coolant, allowing the coolant to quickly recover from a low temperature to a certain temperature, reducing the impact of low temperature on the coolant and ensuring rapid coolant flow. Furthermore, when the subsequent cables and charging gun generate high heat, the position of the movable base can be changed again to ensure timely heat dissipation of the coolant by the finned tube, thus guaranteeing the stable operation of the charging pile.

[0042] 2. In this invention, by setting a cooling component, the cooling sleeve can be compressed by the compression block when the cooling sleeve is connected to the charging terminal, causing the cooling sleeve to shrink. This ensures a tight connection between the cooling sleeve and the charging terminal and avoids gaps, eliminating the need to fill the gaps with a heat-conducting medium, thus preventing the heat-conducting medium from aging and affecting the cooling efficiency. At the same time, the charging terminal can be supported by a support base to prevent bending of the charging terminal due to the shrinkage of the cooling sleeve.

[0043] 3. In this invention, by setting up an exhaust assembly, the design enables the grid plate to intercept air bubbles as the coolant enters the mounting housing during the coolant circulation process, preventing the bubbles from continuing to flow with the coolant and ensuring the stable operation of the device. As the gas gradually increases, the liquid level inside the exhaust housing gradually decreases, allowing the float to fall and the gas to be discharged to the outside, thus preventing excessive gas accumulation and re-entry into the coolant, which would affect the coolant circulation.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figures 1-10 This invention provides a technical solution: a car charging pile with a high-efficiency heat dissipation mechanism, including a cabinet 1, a cable 2 on one side of the cabinet 1, a charging gun 3 at one end of the cable 2, and further including:

[0058] The heat dissipation component 4 includes a finned tube 401 disposed inside the cabinet 1, which is used to cool the coolant flowing through it.

[0059] Cooling component 6 includes a cooling sleeve 604 disposed on the outer wall of the charging terminal inside the charging gun 3. Coolant flows inside the cooling sleeve 604 to cool the charging terminal inside the charging gun 3.

[0060] The exhaust assembly 5 includes an exhaust shell 507 disposed on one side of the cooling jacket 604, through which the exhaust shell 507 is used to separate and discharge the gas in the coolant circuit.

[0061] like Figures 4-6 As shown, the heat dissipation assembly 4 also includes: a mounting base 404, a ball core 408, and a mounting shaft 415;

[0062] Mounting base 404 is located at the bottom corner of fin tube 401, and mounting base 404 has a through hole communicating with fin tube 401. Ball core 408 is rotatably mounted inside mounting base 404, and ball core 408 has a through hole corresponding to the inside of mounting base 404. Rotating ball core 408 controls the opening and closing of the through hole inside mounting base 404. Mounting shaft 415 is mounted on the outer wall of ball core 408, and mounting shaft 415 is rotatably mounted in the groove inside mounting base 404.

[0063] The heat dissipation assembly 4 also includes: a rotating frame 414, a ratchet disk 413, and a push rod 411;

[0064] The rotating frame 414 is installed on the outer wall of the mounting shaft 415, and a spring pin is provided on one side of the rotating frame 414. The mounting base 404 is provided with a groove corresponding to the spring pin. The rotation of the rotating frame 414 drives the ball core 408 to rotate, which is used to control the on / off state of the through hole inside the mounting base 404. The ratchet disk 413 is installed at one end of the mounting shaft 415, and the ratchet disk 413 is fixedly connected to the mounting base 404. The ratchet disk 413 is used to prevent the rotating frame 414 from rotating in the opposite direction. The push rod 411 is slidably installed in the groove inside the mounting base 404, and a lever 412 is rotatably installed at one end of the push rod 411. A stop block corresponding to the lever 412 is provided at one end of the push rod 411. The movement of the push rod 411 drives the lever 412 to move the rotating frame 414, thereby causing the ball core 408 to rotate.

[0065] The heat dissipation assembly 4 also includes: a guide rod 409 and a movable base 406;

[0066] The guide rod 409 is installed at the top of the push rod 411, and the guide rod 409 is slidably connected to the mounting base 404 through the internal sliding groove of the mounting base 404. The outer wall of the guide rod 409 is fitted with a spring 410, which pushes the push rod 411 to reset. The movable base 406 is slidably disposed inside the mounting base 404, and the movable base 406 has a through hole corresponding to the through hole inside the mounting base 404. The movable base 406 has movable modules 407 on both sides, and a pressing groove corresponding to the push rod 411 is provided on one side of the movable base 406. The push rod 411 is pushed by the protrusion inside the pressing groove, which causes the ball core 408 to rotate, thereby connecting the movable base 406 with the fin tube 401.

[0067] The heat dissipation assembly 4 also includes: an input pipe 405 and a circulation pump 402;

[0068] The input pipe 405 is installed at the bottom of the movable base 406 and is connected to the internal through hole of the movable base 406. The coolant is delivered through the input pipe 405 to the finned tube 401 for heat dissipation by passing through the movable base 406 and the ball core 408. The circulation pump 402 is located at one end of the outlet of the finned tube 401 and the output end of the circulation pump 402 is equipped with an output pipe 403. The circulation pump 402 is used to drive the coolant circulation.

[0069] In another embodiment, the mobile module 407 is well known in the art and therefore is not described in detail herein.

[0070] Specifically: During the charging process of the charging station, the circulating pump 402 can drive the coolant through the output pipe 403 and the inlet pipe 607 to the cooling jacket 604 to cool the charging terminals and the charging gun 3. The coolant can then be returned to the finned tube 401 through the discharge pipe 501 and the input pipe 405 for heat dissipation. Since both the output pipe 403 and the input pipe 405 pass through the cable 2, the cable 2 can be cooled.

[0071] Furthermore, when used in environments with low temperatures, such as winter, the coolant will become viscous due to the low temperature. Therefore, the moving module 407 can drive the moving base 406 to move to the bottom corner of the corresponding finned tube 401 to change the flow path length of the coolant inside the finned tube 401, thereby adjusting the heat dissipation of the finned tube 401 on the coolant. During the movement of the moving base 406, the circulation pump 402 is temporarily shut off and turned on when the moving base 406 is reconnected.

[0072] Furthermore, during the movement of the movable seat 406, since the movable seat 406 has a pressing groove on one side corresponding to the push rod 411, the protrusion on the inner wall of the pressing groove can be used to push the push rod 411, thereby causing the push rod 411 to rise and use the lever 412 to push the rotating frame 414, so that the rotation of the rotating frame 414 drives the ball core 408 to rotate, thereby connecting the through hole inside the ball core 408 with the through hole inside the mounting seat 404 and the movable seat 406, and allowing the coolant to enter the fin tube 401;

[0073] Furthermore, when the lever 412 moves the rotating frame 414 to rotate a certain angle, since the rotating frame 414 is provided with a spring pin on one side and the mounting base 404 is provided with a groove corresponding to the spring pin, the rotating frame 414 can rotate a certain angle under the pressure between the spring pin and the groove, ensuring that the ball core 408 can rotate stably by ninety degrees. When the through hole inside the moving base 406 corresponds to the through hole of the ball core 408, the bottom end of the push rod 411 is between two protrusions in the extrusion groove. Therefore, when the moving base 406 is moved away, the other protrusion can be used to push the push rod 411 to make the ball core 408 rotate and block the through hole inside the mounting base 404.

[0074] like Figure 7 , Figure 8 As shown, the cooling component 6 also includes: a support base 606, a telescopic tube 605, and a liquid inlet tube 607;

[0075] The support base 606 is located inside the cooling sleeve 604 and between the two charging terminals. The support base 606 is used to support the charging terminals. The telescopic tube 605 is installed on the upper and lower sides of the support base 606, and multiple telescopic tubes 605 are arranged linearly. The other end of the telescopic tube 605 is connected to the cooling sleeve 604. The telescopic tube 605 delivers coolant to the inside of the support base 606 to cool the charging terminals. The liquid inlet pipe 607 is installed on one side of the cooling sleeve 604, and the other end of the liquid inlet pipe 607 is connected to the output pipe 403.

[0076] The cooling component 6 also includes: a fixing sleeve 603, a pressing block 602, and a bolt 601;

[0077] The fixing sleeve 603 is disposed inside the charging gun 3 and is fitted onto the outer wall of the cooling sleeve 604. The extrusion block 602 is disposed inside the fixing sleeve 603 and the bottom end of the extrusion block 602 contacts the outer wall of the cooling sleeve 604. The extrusion block 602 extrudes the cooling sleeve 604 to tighten it inward. The bolt 601 is rotatably disposed in the through hole on the outer wall of the fixing sleeve 603 and is threadedly connected to the extrusion block 602 through the threaded hole on the top surface of the extrusion block 602. Multiple bolts 601 are arranged linearly.

[0078] In another embodiment, the cooling sleeve 604 can be configured according to the number of charging terminals inside the charging gun 3.

[0079] Specifically: When cooling the charging terminal, the cooling sleeve 604 and the support base 606 can be connected, and the coolant can flow into the cooling sleeve 604 from the inlet pipe 607. At the same time, the telescopic pipe 605 can be used to allow the coolant to enter the support base 606, thereby ensuring the cooling effect on the charging terminal.

[0080] Furthermore, the compression block 602 can be moved by rotating the bolt 601 to compress the cooling sleeve 604, thereby causing the cooling sleeve 604 to contract inward. This ensures that the cooling sleeve 604 is tightly connected to the charging terminal. Since the support base 606 is located between the two charging terminals, it can support the charging terminals and prevent the charging terminals from shifting due to excessive compression force of the cooling sleeve 604.

[0081] like Figure 9 , Figure 10 As shown, the exhaust assembly 5 also includes: a mounting housing 502 and an exhaust pipe 501;

[0082] Mounting housing 502 is installed at the bottom of exhaust housing 507 and is connected to exhaust housing 507. Discharge pipe 501 is installed inside mounting housing 502, and one end of discharge pipe 501 is connected to one side of cooling sleeve 604, and the other end of discharge pipe 501 is connected to input pipe 405.

[0083] The exhaust assembly 5 also includes: a grille 508 and a float 505;

[0084] The grid plate 508 is installed inside the mounting housing 502 to collect air bubbles inside the coolant. The float ball 505 is located inside the exhaust housing 507, and the through hole inside the exhaust housing 507 corresponds to the float ball 505. The float ball 505 blocks the through hole inside the exhaust housing 507 to control the communication state of the exhaust housing 507.

[0085] The exhaust assembly 5 also includes: a sealing ring 506 and a fixing rod 503;

[0086] A sealing ring 506 is installed on the outer wall of the float 505, a fixing rod 503 is installed on the top of the float 505, and a limiting plate 504 is installed on the top of the fixing rod 503, and the limiting plate 504 is slidably disposed in the through hole of the exhaust shell 507.

[0087] Specifically: When the coolant flows out of the cooling jacket 604 and enters the mounting shell 502, because the mounting shell 502 is equipped with a grid plate 508, when the coolant passes through the grid plate 508, the air bubbles in the coolant will come into contact with the grid plate 508, thereby intercepting the air bubbles through the grid plate 508. And because the grid plate 508 is placed at an angle, the air bubbles will gradually move upward and enter the exhaust shell 507.

[0088] Furthermore, as the gas inside the exhaust casing 507 gradually increases, the coolant level inside the exhaust casing 507 will gradually drop. When the level drops below the lowest point of the float 505, the float 505 will move downwards by a certain distance under the influence of gravity.

[0089] Furthermore, as the float 505 moves downward, it can cause the sealing ring 506 to move downward, thereby exposing the through hole at the upper end of the vent housing 507 and connecting the vent housing 507 with the outside, allowing gas to be discharged to the outside. As the gas is discharged, the liquid level can rise again, which can then cause the float 505 to move upward to re-seal. At the same time, an exhaust pipe is connected to the outside of the vent housing 507, and the exhaust pipe is in contact with the output pipe 403 inside the charging gun 3, and the outlet of the exhaust pipe extends to the outside of the charging gun 3.

[0090] Working principle: During assembly, the cooling sleeve 604, support base 606, and charging terminal are connected. The compression block 602 is pushed by the bolt 601 to compress the cooling sleeve 604, making the cooling sleeve 604 tight. During use, the coolant is circulated by the circulation pump 402 and cooled by the finned tube 401. In cold environments such as winter, the position of the moving base 406 can be changed, and the ball core 408 connects the moving base 406 to the inside of the finned tube 401, thereby changing the flow path of the coolant inside the finned tube 401. During the coolant circulation process, air bubbles inside the coolant can be collected by the grid plate 508. When the air bubbles accumulate to a certain extent, the liquid level inside the exhaust shell 507 drops, causing the float ball 505 to drop, allowing the gas to be discharged from the through hole inside the exhaust shell 507.

[0091] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
