[0001] The present invention relates to the technical field of automobile charging piles, and more specifically, to a liquid cooling and heat dissipation automobile charging pile with leakage warning and an early warning device. Background Art

[0002] A car charging pile is a charging device designed specifically for electric vehicles. It charges the battery of an electric vehicle by providing electricity. Charging piles are usually installed in public places, parking lots, home garages, etc. to provide convenience for electric vehicle users.

[0003] The charging pile will generate more heat when in use, causing the temperature inside the charging pile to rise. Generally, the high-temperature air inside is discharged through the heat dissipation holes through the heat dissipation fan to achieve heat dissipation of the charging pile. In order to improve the heat dissipation effect, some charging piles will use liquid cooling. However, for some extreme weather in summer or high-temperature areas, the temperature of the cooling water gradually increases with the process of liquid cooling, resulting in a significant decrease in the heat dissipation effect, which cannot meet normal heat dissipation needs.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Conductive refrigeration plate 602, the left side of the semiconductor refrigeration plate 602 is fixedly connected to a thermal conductive plate 603, the left side of the thermal conductive plate 603 is fixedly connected to a thermal conductive plate 604, a circulating water pump 605 is installed at the bottom of the inner side of the water tank 601, and a circulating water inlet 611 is opened at the top of the back side of the water tank 601. The second heat dissipation component 7 includes a fixed plate 701 fixedly connected to the inner wall of the charging pile body 101, the inner side of the fixed plate 701 is fixedly connected to a fixed water pipe 702, the outer side of the fixed water pipe 702 is fixedly sleeved with a second heat sink 703, the back side of the fixed water pipe 702 is fixedly connected to a connecting pipe 704, the other end of the connecting pipe 704 is fixedly connected to the circulating water inlet 611, and the front side of the fixed water pipe 702 is fixedly connected to the outlet of the cooling water coil 5.

[0022] In the embodiment of the present application, the device temperature sensor 111 can monitor the temperature inside the charging pile body 101. When the temperature inside the charging pile body 101 exceeds the set range, starting the second heat dissipation fan 113 can accelerate the air flow and discharge the high-temperature air inside the charging pile body 101 to the outside, so that the low-temperature air outside enters the inside of the charging pile body 101 to achieve heat dissipation. When the second heat dissipation fan 113 cannot adjust the temperature inside the charging pile body 101 to the normal working temperature, the circulation of cooling water can be achieved through the circulating water pump 605. The cooling water enters the inside of the cooling water coil 5 through the outlet of the circulating water pump 605. Water has a large specific heat capacity and can absorb the high-temperature heat inside the charging pile body 101, so that the temperature of the cooling water increases.

When the above method still cannot lower the temperature inside the charging pile body 101 to the normal working temperature, the cooling water inside the water tank 601 can be cooled by the semiconductor refrigeration sheet 602. The left side of the semiconductor refrigeration sheet 602 is the cooling surface, and the right side of the semiconductor refrigeration sheet 602 is the heat dissipation surface. The cooling water of the cooling surface of the semiconductor refrigeration sheet 602 can be quickly cooled by the thermal conductive plate 603 and the thermal conductive plate 604, thereby increasing the temperature difference between the cooling water in the cooling water coil 5 and the air inside the charging pile body 101, greatly improving the cooling effect on the inside of the charging pile body 101, and the heat dissipation plate 201, the first heat dissipation sheet 202 and the first heat dissipation fan 203 can quickly dissipate the heat dissipation surface of the semiconductor refrigeration sheet 602, thereby ensuring the cooling effect on the left side of the semiconductor refrigeration sheet 602.

[0024] When the charging pile body 101 is working, or when the cooling water flows inside the cooling water coil 5, the cooling water coil 5 will inevitably vibrate. The fastener 402 fixes the cooling water coil 5 to prevent the cooling water coil 5 from deforming or even breaking during use.

[0025] Among them, a water temperature sensor 606 is installed on the left side of the inner wall of the water tank 601, and the water temperature sensor 606 is electrically connected to the semiconductor cooling plate 602.

[0026] The water temperature sensor 606 can monitor the temperature of the cooling water inside the water tank 601. When the temperature of the cooling water is lower than the set temperature, the water temperature sensor 606 transmits a signal to the semiconductor refrigeration chip 602, and the semiconductor refrigeration chip 602 stops working to prevent the cooling water from freezing.

[0027] The first heat dissipation component 2 includes a heat dissipation plate 201 fixedly connected to the right side of the semiconductor refrigeration sheet 602 , a first heat dissipation fin 202 is fixedly connected to the right side of the heat dissipation plate 201 , and a first heat dissipation fan 203 is installed on the right side of the first heat dissipation fin 202 .

[0029] A heat dissipation channel 112 is provided at the bottom of the right side of the charging pile body 101 , and a second heat dissipation fan 113 is installed inside the heat dissipation channel 112 .

[0030] The second heat dissipation fan 113 can accelerate the air flow to achieve air cooling and heat dissipation inside the charging pile body 101 and heat dissipation of the second heat sink 703 .

[0031] Among them, the protection component 3 includes a fixed frame 301 fixedly connected to the right side of the heat dissipation channel 112, a fixed louver 302 is fixedly connected to the inner side of the fixed frame 301, a dustproof net 303 is installed on the right side of the inner side of the fixed frame 301, an installation groove 311 is opened on the top of the fixed frame 301, and positioning grooves 312 are opened on the front and back sides of the inner wall of the fixed frame 301, and the installation groove 311 and the positioning groove 312 are both slidably connected with the dustproof net 303.

[0033] Among them, it includes a liquid level monitoring component 607 and a pressure sensor 608. The pressure sensor 608 is installed at the bottom of the inner wall of the water tank 601. The liquid level monitoring component 607 includes a fixed rod 671 fixedly connected to the inner side of the water tank 601. The inner side of the fixed rod 671 is fixedly connected with a fixed tube 672. The inner side of the fixed tube 672 is movably sleeved with a movable rod 673. The top of the movable rod 673 is fixedly connected with a buoyancy frame 674. It also includes a voice player 103 and a communication module 104. The communication module 104 is installed at the top of the charging pile body 101. The voice player 103 is installed at the top of the front of the charging pile body 101.

[0034] The communication module 104 adopts a GSM communication module, through which the signal data of the pressure sensor 608 can be sent to the management terminal of the administrator. The communication module 104 is a common prior art and will not be described in detail in this application.

[0035] When the cooling water leaks, the water level inside the water tank 601 will drop, and the movable rod 673 and the buoyancy frame 674 will drop as the water level drops, so that the movable rod 673 squeezes the pressure sensor 608, and then the pressure sensor 608 transmits the signal to the voice player 103 and the communication module 104. The voice player 103 can remind the user that the charging pile is faulty and cannot be used. The communication module 104 can send the leakage information to the administrator's monitoring terminal, thereby reminding the administrator to deal with it in time, thereby realizing liquid level monitoring and early warning.

[0036] It also includes a conical frame 705, which is fixedly connected to the bottom of the fixed plate 701, and a liquid sensor 706 is fixedly connected to the bottom of the inner side of the conical frame 705.

[0037] The liquid sensor 706 is a conductive liquid leakage sensor based on the conductivity of the liquid. When the liquid passes through the electrode of the sensor, the conductivity will change, thereby triggering a signal output.

[0038] The water circulation component 6 is located directly above the conical frame 705. When the water tank 601 leaks, the cooling water will fall into the inner side of the conical frame 705 under the action of gravity. When the cooling water contacts the liquid sensor 706, the liquid sensor 706 can transmit the signal to the voice player 103 and the communication module 104, thereby realizing liquid monitoring and early warning.

[0039] The working principle and use process of the present invention: The device temperature sensor 111 can monitor the temperature inside the charging pile body 101. When the temperature inside the charging pile body 101 exceeds the set range, starting the second heat dissipation fan 113 can accelerate the air flow, discharge the high-temperature air inside the charging pile body 101 to the outside, so that the low-temperature air outside enters the charging pile body 101 to dissipate heat. When the second heat dissipation fan 113 cannot adjust the temperature inside the charging pile body 101 to the normal working temperature, the circulation of cooling water can be realized through the circulating water pump 605. The cooling water enters the cooling water coil 5 through the outlet of the circulating water pump 605. Water has a large specific heat capacity and can absorb the high-temperature heat inside the charging pile body 101, so that the temperature of the cooling water increases. The heat of the cooling water is transferred to the second heat sink 703 through the fixed water pipe 702. The second heat sink 703 is dissipated by the second heat dissipation fan 113, thereby cooling the cooling water. The cooled cooling water finally flows back to the inside of the charging pile body 101 through the connecting pipe 704. When the above method still cannot lower the temperature inside the charging pile body 101 to the normal working temperature, the cooling water inside the water tank 601 can be cooled by the semiconductor refrigeration sheet 602. The left side of the semiconductor refrigeration sheet 602 is the cooling surface, and the right side of the semiconductor refrigeration sheet 602 is the heat dissipation surface. The cooling water of the cooling surface of the semiconductor refrigeration sheet 602 can be quickly cooled by the thermal conductive plate 603 and the thermal conductive plate 604, thereby increasing the temperature difference between the cooling water in the cooling water coil 5 and the air inside the charging pile body 101, greatly improving the cooling effect on the inside of the charging pile body 101, and the heat dissipation plate 201, the first heat dissipation sheet 202 and the first heat dissipation fan 203 can quickly dissipate the heat dissipation surface of the semiconductor refrigeration sheet 602, thereby ensuring the cooling effect on the left side of the semiconductor refrigeration sheet 602.

[0040] When the cooling water leaks, the water level inside the water tank 601 will drop, and the movable rod 673 and the buoyancy frame 674 will drop as the water level drops, so that the movable rod 673 squeezes the pressure sensor 608, and then the pressure sensor 608 transmits the signal to the voice player 103 and the communication module 104. The voice player 103 can remind the user that the charging pile is faulty and cannot be used, and the communication module 104 can send the leakage information to the administrator's monitoring terminal, so as to remind the administrator to deal with it in time, realizing the liquid level monitoring early warning; The water circulation component 6 is located directly above the conical frame 705. When the water tank 601 leaks, the cooling water will fall into the inner side of the conical frame 705 under the action of gravity. When the cooling water contacts the liquid sensor 706, the liquid sensor 706 can transmit the signal to the voice player 103 and the communication module 104, thereby realizing liquid monitoring and early warning.
