Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a liquid-cooled supercharging pile. Background Technology

[0002] As more and more car owners choose new energy vehicles, their share of the automotive market is gradually increasing. However, compared to traditional gasoline vehicles that use gasoline for energy storage, most new energy vehicles require a longer charging time when charging. Current technology uses supercharging stations to increase charging power, but this increased power requires the charging cables connecting the new energy vehicle and the charging station to withstand greater charging loads, causing the battery cells in the cables to generate significant heat. Therefore, when using supercharging stations, heat dissipation measures are necessary for the internal components of the charging cables to prevent accidents caused by overheating.

[0003] In existing technologies, the charging cable is cooled by a cooling pipe laid inside the charging cable, and a cooling chamber is arranged at the charging terminal of the charging gun to wrap the main heat-generating battery cells, thereby cooling the main heat-generating areas at the charging terminal. However, existing technologies usually involve continuous circulation of coolant inside the cooling pipe for cooling. Traditional liquid-cooled supercharging piles directly start at maximum cooling capacity and maximum circulation speed during operation. This excessive cooling capacity increases the power consumption of the liquid-cooled supercharging pile, and the coolant stays at the heat-generating parts of the cable for a short time, which cannot achieve sufficient heat exchange. Furthermore, the time for the coolant to exchange heat with the outside environment is also limited in the heat sink section, resulting in limited efficiency of the cooling equipment. There is room for improvement. Therefore, a liquid-cooled supercharging pile is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a liquid-cooled supercharging pile. This solves the problems of traditional liquid-cooled supercharging piles, which directly activate the maximum cooling capacity and maximum circulation speed during operation, resulting in excessive cooling capacity that increases power consumption. Furthermore, the coolant stays at the heating point of the cable for a short time, failing to achieve sufficient heat exchange, and the coolant also has limited time to exchange heat with the outside environment while in the radiator, leading to limited cooling equipment efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a liquid-cooled supercharging pile, comprising:

[0006] The cooling pipeline is installed inside the cable. The cooling pipeline includes an exchange pipeline and a circulation pipeline. The exchange pipeline is distributed in a spiral shape at the main heat-generating points inside the cable. The circulation pipeline is connected to the exchange pipeline.

[0007] A switching end, which is connected to the exchange pipeline and the circulation pipeline, and the switching end, the circulation pipeline and the exchange pipeline form an internal circulation;

[0008] A heat dissipation component, the heat dissipation component being filled with coolant, the heat dissipation component being used to cool the coolant;

[0009] The switching end is also provided with two sets of connecting pipes for connecting heat dissipation components, and the switching end, connecting pipes and heat dissipation components form an external circulation;

[0010] The switching end is equipped with a first switching valve, which is used to switch the internal and external circulation paths of the coolant.

[0011] Furthermore, the switching head is provided with a first chamber, a second chamber, a third chamber, and a fourth chamber;

[0012] The first chamber and the second chamber are respectively connected to the circulation pipeline and the exchange pipeline;

[0013] The third and fourth chambers are connected to the two sets of connecting pipes;

[0014] A connecting hole is provided between the first chamber and the third chamber, and between the second chamber and the fourth chamber;

[0015] The first switching valve is disposed between the first chamber and the second chamber;

[0016] The first switching valve is provided with a blocking block corresponding to the connecting hole;

[0017] The first switching valve rotates to block the connecting hole via the sealing block, thus connecting the first chamber and the second chamber; conversely,

[0018] The first switching valve rotates to separate the first chamber and the second chamber, and removes the blocking block that blocks the connecting hole, so that the first chamber and the third chamber, and the second chamber and the fourth chamber are connected respectively.

[0019] Furthermore, the switching head is equipped with a drive unit and a temperature sensor;

[0020] The temperature sensor is used to detect the temperature of the coolant in the internal circulation path;

[0021] The drive unit is used to drive the first switching valve to rotate 90 degrees.

[0022] Furthermore, the switching end is also equipped with a first circulation pump corresponding to the circulation pipeline and the exchange pipeline.

[0023] Furthermore, the heat dissipation component includes a first liquid storage tank, a second liquid storage tank, and a heat exchange pipe connecting the two.

[0024] It also includes a second circulation pump and a circulation pipe connecting the first and second storage tanks;

[0025] The second circulation pump is equipped with a second switching valve at its input end, and the second switching valve is connected to the circulation pipe and a set of connecting pipes.

[0026] Furthermore, the heat dissipation component also includes a heat dissipation fan disposed below the heat exchange pipe.

[0027] Furthermore, a partition is provided between the first chamber and the second chamber, and the partition is provided with a flow section corresponding to the first switching valve;

[0028] Magnetic elements are provided both inside the flow section and on the first switching valve.

[0029] Furthermore, it also includes a control unit, which is electrically connected to a temperature sensor, a first switching valve, a first circulating pump, a second switching valve, and a second circulating pump.

[0030] Furthermore, the driving unit is a temperature-sensing power component, which has a double-helix metal structure. One end of the temperature-sensing power component is fixedly connected to the first switching valve, and the other end of the temperature-sensing power component is fixedly connected to the switching end.

[0031] The beneficial effects of this invention are reflected in:

[0032] This invention allows switching the internal and external circulation paths of the coolant in the cooling pipeline via a switching terminal. During internal circulation, the coolant can flow within the exchange and circulation pipelines, continuously exchanging heat with the cables. When the coolant temperature reaches a set value, the switching terminal switches again, allowing the cooling pipeline to interact with the coolant inside the heat dissipation component. The coolant at lower temperatures enters the cooling pipeline, while the coolant at higher temperatures enters the heat dissipation component for circulation and heat dissipation. This solves the problem of traditional liquid-cooled supercharging piles directly activating maximum cooling capacity and maximum circulation speed during operation, resulting in excessive cooling capacity and increased power consumption.

[0047] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0048] Please see Figures 1-9 This invention discloses a liquid-cooled supercharging pile, comprising:

[0049] The cooling pipeline 1 is installed inside the cable 01. The cooling pipeline 1 includes an exchange pipeline 11 and a circulation pipeline 12. The exchange pipeline 11 is spirally distributed inside the main heat-generating parts of the cable 01. The circulation pipeline 12 is connected to the exchange pipeline 11.

[0050] Switching end 2, the switching end 2 is connected to the exchange pipeline 11 and the circulation pipeline 12, and the switching end 2, the circulation pipeline 12 and the exchange pipeline 11 form an internal circulation;

[0051] Heat dissipation component 3, the heat dissipation component 3 is filled with coolant, the heat dissipation component 3 is used to cool the coolant, the coolant is water or other liquid;

[0052] The switching end 2 is also provided with two sets of connecting pipes 21 for connecting the heat dissipation component 3. The switching end 2, the connecting pipes 21 and the heat dissipation component 3 form an external circulation.

[0053] The switching end 2 is equipped with a first switching valve 22, which is used to switch the internal and external circulation paths of the coolant.

[0054] In use, this application allows switching the internal and external circulation paths of the coolant in the cooling pipe 1 via the switching end 2. During the internal circulation process, such as Figure 8 As shown, the coolant can circulate within the exchange pipe 11 and the circulation pipe 12, continuously exchanging heat with cable 01. When the coolant temperature reaches the set value, the switching terminal 2 switches again, exchanging the coolant in the cooling pipe 1 with the coolant inside the heat dissipation component 3. The lower temperature coolant enters the cooling pipe 1, while the higher temperature coolant enters the heat dissipation component 3 for circulation and heat dissipation. Figure 9 As shown, this addresses the problem that traditional liquid-cooled supercharging piles directly activate maximum cooling capacity and maximum circulation speed during operation, resulting in excessive cooling capacity and increased power consumption. At the same time, it avoids the problem that the coolant stays at the heating point of the cable for a short time, which prevents sufficient heat exchange, and that the coolant also has limited time to exchange heat with the outside environment while in the radiator, leading to limited efficiency of the cooling equipment.

[0055] Specifically, such as Figure 7 As shown, the switching end 2 is provided with a first chamber 201, a second chamber 202, a third chamber 203 and a fourth chamber 204, wherein the switching end 2 is provided with a partition to separate the above chambers;

[0056] The first chamber 201 and the second chamber 202 are respectively connected to the circulation pipeline 12 and the exchange pipeline 11;

[0057] The third chamber 203 and the fourth chamber 204 are connected to the two sets of connecting pipes 21;

[0058] A connecting hole 205 is provided between the first chamber 201 and the third chamber 203, and between the second chamber 202 and the fourth chamber 204;

[0059] The first switching valve 22 is disposed between the first chamber 201 and the second chamber 202;

[0060] The first switching valve 22 is provided with a blocking block 23 corresponding to the connecting hole 205. The diameter of the blocking block 23 is larger than that of the connecting hole 205. When the first switching valve 22 rotates, the blocking block 23 can completely cover the connecting hole 205 and block it.

[0061] The first switching valve 22 is used in the following steps:

[0062] The first switching valve 22 rotates to block the connecting hole 205 via the sealing block 23, and connects the first chamber 201 and the second chamber 202; conversely,

[0063] The first switching valve 22 rotates to separate the first chamber 201 and the second chamber 202, and removes the blocking block 23 that blocks the connecting hole 205, so that the first chamber 201 and the third chamber 203, the second chamber 202 and the fourth chamber 204 are connected respectively.

[0064] It should be added that, in order to detect problems with the coolant in the internal circulation, the switching terminal 2 is equipped with a drive unit 24 and a temperature sensor.

[0065] The temperature sensor is used to detect the temperature of the coolant in the internal circulation path;

[0066] The drive unit 24 is used to drive the first switching valve 22 to rotate ninety degrees.

[0067] It should be added that the switching end 2 is also equipped with a first circulation pump 25 corresponding to the circulation pipeline 12 and the exchange pipeline 11.

[0068] During the above process, the temperature sensor, drive unit 24, and first circulation pump 25 are linked. When the temperature sensor detects that the coolant temperature reaches a specified value during the circulation process in the cooling pipeline 1, the drive unit 24 drives the first switching valve 22 to rotate, thereby connecting the first chamber 201 and the third chamber 203, the second chamber 202 and the fourth chamber 204 respectively, so that the coolant in the cooling pipeline 1 can exchange with the coolant in the heat dissipation component 3. Afterwards, when the temperature sensor detects that the coolant temperature in the cooling pipeline 1 has dropped to a specified value, the drive unit 24 drives the first switching valve 22 to rotate again, connecting the first chamber 201 and the second chamber 202, and starting the first circulation pump 25. The first circulation pump 25 drives the coolant inside the first chamber 201 and the second chamber 202 to circulate, and repeats the above steps to circulate and cool the equipment.

[0069] It should be further added that the heat dissipation component 3 includes a first liquid storage tank 31, a second liquid storage tank 32, and a heat exchange pipe 33 connecting the two.

[0070] It also includes a second circulation pump 34 and a circulation pipe 37 connecting the first liquid storage tank 31 and the second liquid storage tank 32;

[0071] The input end of the second circulating pump 34 is provided with a second switching valve 36, which is connected to the circulating pipe 37 and a set of connecting pipes 21.

[0072] Meanwhile, the heat dissipation component 3 also includes a heat dissipation fan 35 disposed below the heat exchange pipe 33.

[0073] In the heat dissipation component 3, the coolant's path during external circulation is as follows: the second switching valve 36 connects the connecting pipe 21 and the first reservoir 31. Driven by the second circulation pump 34, the coolant is drawn from the cooling pipeline 1 into the first reservoir 31, and then passes through the heat exchange pipe 33 into the second reservoir 32. After that, it is input back into the cooling pipeline 1 through the connecting pipe 21.

[0074] In the internal circulation process of the heat dissipation component 3, the path of the coolant is as follows: the second switching valve 36 connects the circulation pipe 37 and the first reservoir 31. Driven by the second circulation pump 34, the coolant in the circulation pipe 37 is drawn into the first reservoir 31, and then the coolant passes through the heat exchange pipe 33 and enters the second reservoir 32. After that, it is fed back into the first reservoir 31 through the circulation pipe 37, so that the coolant circulates through the heat exchange pipe 33 and is cooled down by the action of the cooling fan 35.

[0075] It should be added that a partition is provided between the first chamber 201 and the second chamber 202, and a flow section 221 corresponding to the first switching valve 22 is provided on the partition;

[0076] Both the flow section 221 and the first switching valve 22 are provided with magnetic suction components 222, which are used to improve the rotation accuracy of the first switching valve 22.

[0077] Finally, it should be added that a control unit is also included, which is electrically connected to the temperature sensor, the first switching valve 22, the first circulation pump 25, the second switching valve 36, and the second circulation pump 34.

[0078] In another embodiment of this application, the driving unit 24 is a temperature-sensing power component, which is a double-helix metal structure. One end of the temperature-sensing power component is fixedly connected to the first switching valve 22, and the other end of the temperature-sensing power component is fixedly connected to the switching end 2. In the above, the double-helix metal structure can bend and rotate when the temperature changes significantly, thereby driving the first switching valve 22 to rotate, thereby realizing the self-opening and closing of the switching end 2.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
