[0002] When the charging gun is charging, the cables inside the charging gun will generate a lot of heat. In related technologies, liquid cooling pipes are installed inside the charging gun to exchange heat with the cables, so as to reduce the temperature of the cables and ensure the normal operation of the charging gun.

[0003] However, the heat exchange efficiency of using liquid cooling to dissipate heat from the cable is relatively low, which affects the normal use of the charging gun. Summary of the Invention

[0004] The purpose of this disclosure is to provide a charging gun and a charging device, wherein the charging gun is provided with an internal eddy current tube to at least partially solve the above-mentioned technical problems.

[0007] Optionally, multiple cables are provided, and the cooling component further includes a flow divider. The flow divider has a first interface and multiple second interfaces. The first interface is connected to the cold air exhaust section, and the multiple second interfaces are connected to the first cooling channels of the multiple cables in a one-to-one correspondence.

[0008] Optionally, the refrigeration assembly further includes a connecting hose, through which the cold air exhaust section is connected to the first interface; and / or, each of the second interfaces is provided with a flow regulating valve; and / or, the flow divider has a third interface, which communicates with the second cooling channel.

Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, the terms "first," "second," and "third," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. Additionally, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0021] The charging cabinet and charging device in the exemplary embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0022] refer to Figures 1 to 7As shown, in a first aspect of this disclosure, a charging gun is provided, including a charging gun housing 1, a cable 2, a cooling channel 4, and a cooling assembly 3. The charging gun housing 1 has an internal mounting chamber 11; a portion of the cable 2 is located within the mounting chamber 11; a cooling channel 4 is provided inside the cable 2 and / or within the mounting chamber 11, the cooling channel 4 being used for heat exchange with the cable 2; the cooling assembly 3 includes a vortex tube 31, which is installed within the mounting chamber 11. The vortex tube 31 has an air inlet 5 and a cold air outlet 6. The air inlet 5 is connected to a compressed gas supply device, and the cold air outlet 6 is connected to the cooling channel 4.

[0023] When the charging gun is working, the compressed gas supply device will introduce high-pressure gas into the vortex tube 31 through the air inlet 5. The high-pressure gas will generate cold air in the vortex tube 31. The cold air will enter the cooling channel 4 through the cold air discharge part 6 to exchange heat with the cable 2.

[0024] The vortex tube 31 is installed in the mounting chamber 11, which can shorten the distance between the vortex tube 31 and the cooling channel 4. This reduces the energy loss of the cold air during the flow from the vortex tube 31 to the cooling channel 4, thereby achieving efficient heat exchange between the cold air and the cable 2, improving the heat dissipation efficiency of the cold air on the cable 2, and ensuring the normal use of the charging gun.

[0025] It is understandable that, such as Figures 2 to 4 as well as Figure 6 As shown, the vortex tube 31 has a swirling channel inside. After the high-pressure gas enters the vortex tube 31, it expands and accelerates within the vortex tube 31, and enters the swirling channel tangentially to form a free vortex. The rotational angular velocity of the free vortex increases closer to the center. Due to the difference in angular velocity, friction is generated between the layers of the free vortex. The airflow angular velocity is the largest in the central part. After friction between the layers of the vortex, energy is transferred to the outer layer airflow with a lower angular velocity. The airflow in the central layer loses energy, has low kinetic energy, and its speed and temperature decrease, thus forming cold air, which enters the cooling channel 4 through the cold air discharge part 6.

[0026] Correspondingly, the airflow in the outer layer gains momentum and its kinetic energy increases. At the same time, it rubs against the wall of the vortex tube 31, thus converting some of the kinetic energy into heat energy, thereby forming hot air. The hot air can be discharged to the outside of the charging gun housing 1 to prevent the generated hot air from interfering with the heat exchange between the cold air and the cable 2.

[0027] In embodiments of this disclosure, such as Figure 5 As shown, the cooling channel 4 includes a first cooling channel 41, and the cable 2 includes a tubular body 21 and a conductor wire 22. The conductor wire 22 is disposed in the tubular body 21, and the space between the outer surface of the conductor wire 22 and the inner wall of the tubular body 21 forms the first cooling channel 41.

[0028] In other words, after the conductor wire 22 is placed in the tubular body 21, there will be a certain gap between it and the inner wall of the tubular body 21. In this way, the cold air exhaust section 6 connected to the first cooling channel 41 can directly deliver cold air to the gap between the tubular body 21 and the conductor wire 22. The cold air will flow in the gap, thereby allowing the cold air to directly contact the conductor wire 22 for heat exchange. Compared with setting a separate heat exchange pipeline in the tubular body 21, this can avoid the situation where the cold air needs to exchange heat with the pipe wall of the heat exchange pipeline first, and then exchange heat with the conductor wire 22 through the pipe wall of the heat exchange pipeline. This effectively reduces thermal resistance, further reduces the energy loss of the cold air, and improves the heat exchange efficiency between the cold air and the conductor wire 22.

[0029] In addition, the charging gun disclosed herein does not require the installation of heat exchange pipelines, which simplifies the structure of the charging gun, thereby ensuring the heat exchange effect on cable 2, facilitating the manufacturing and molding of the charging gun, and reducing the production cost of the charging gun.

[0030] Furthermore, the diameter of the conductor wire 22 and the diameter of the tubular body 21 can be adaptively adjusted according to requirements, thereby changing the size of the gap between the conductor wire 22 and the tubular body 21, which facilitates changing the flow rate of the cold air entering the first cooling channel 41.

[0031] For example, when the power of the charging gun is high, the diameter of the tubular body 21 can be large to ensure that there is a sufficient gap between the conductor wire 22 and the tubular body 21. In this way, when the charging gun is working and the conductor wire 22 generates a lot of heat, a sufficient amount of cold air can be introduced into the first cooling channel 41 to exchange heat with the conductor wire 22, thereby ensuring the normal use of the charging gun. When the power of the charging gun is low, the diameter of the tubular body 21 can be small, as long as the flow rate of cold air introduced into the first cooling channel 41 is sufficient to effectively dissipate heat from the conductor wire 22.

[0032] In other possible implementations, such as Figure 4 As shown, the cooling channel 4 includes a second cooling channel 42, which is formed by the space between the outer surface of the cable 2 in the mounting chamber 11 and the inner wall of the charging gun housing 1.

[0033] In this way, the cold air generated by the vortex tube 31 can flow into the second cooling channel 42 and enter the installation chamber 11 through the second cooling channel 42. Thus, the cold air can cool the outside of the tubular body 21 to achieve heat exchange between the cold air and the cable 2. The cold air can directly exchange heat with the tubular body 21, which also improves the heat exchange efficiency between the cold air and the conductor wire 22 to a certain extent.

[0034] In embodiments of this disclosure, such as Figure 4 and Figure 5As shown, the cooling channel 4 includes a first cooling channel 41 and a second cooling channel 42. The cable 2 includes a tubular body 21 and a conductor wire 22. The conductor wire 22 is disposed in the tubular body 21. The space between the outer surface of the conductor wire 22 and the inner wall of the tubular body 21 forms the first cooling channel 41. The space between the outer surface of the cable 2 located in the mounting chamber 11 and the inner wall of the charging gun housing 1 forms the second cooling channel 42.

[0035] Therefore, the cold air generated by the vortex tube 31 can simultaneously exchange heat with the conductor wire 22 inside the tubular body 21 and the outside of the tubular body 21. In other words, the cold air can simultaneously reduce the temperature inside and outside the cable 2, thus further improving the heat exchange efficiency between the cold air and the cable 2.

[0036] In some possible implementations, such as Figure 2 As shown, multiple cables 2 can be provided, and the cooling component 3 can also include a flow divider 32. The flow divider 32 has a first interface and multiple second interfaces 321. The first interface is connected to the cold air exhaust section 6, and the multiple second interfaces 321 are connected to the first cooling channels 41 in the multiple cables 2 in a one-to-one correspondence.

[0037] For example, two cables 2 can be provided, and the conductor wires 22 in the two cables 2 can be positive conductor wires and negative conductor wires respectively. The first interface of the shunt 32 can be connected to the inside of the tubular body 21 with the positive conductor wire, and the second interface 321 of the shunt 32 can be connected to the inside of the tubular body 21 with the negative conductor wire. When the charging gun is working, the current passing through the positive conductor wire and the negative conductor wire will cause Joule heating. At this time, the cold air generated by the eddy tube 31 can enter the shunt 32 and enter the first cooling channel 41 in the two cables 2 under the action of the first interface and the second interface 321 of the shunt 32, so as to dissipate heat from the positive conductor wire and the negative conductor wire respectively, thereby ensuring the normal use of the charging gun.

[0038] In addition, the tubular body 21 may have a first tube segment and a second tube segment. The first tube segment may be constructed as a flexible tube segment, that is, the first tube segment may be bent or deformed to a certain extent, thereby facilitating the movement of the cable 2 when the charging gun is in use. The second tube segment may be constructed as a sleeve structure with a certain rigidity and located in the charging gun housing 1, that is, the second tube segment is not easy to bend or deform. The first tube segment may be sleeved on the second tube segment, which facilitates the connection between the second interface 321 of the diverter 32 and the second tube segment, thereby realizing the connection between the diverter 32 and the cable 2.

[0039] In other possible implementations, such as Figure 2 and Figure 3 As shown, the refrigeration component 3 may also include a connecting hose 7, and the cold air exhaust section 6 is connected to the first interface through the connecting hose 7.

[0040] The connecting hose 7 can be bent in the installation chamber 11, which facilitates the connection of the cable 2 and the eddy tube 31 within a limited space.

[0041] Understandably, in order to ensure the effectiveness of the connecting hose 7, a low-temperature resistant hose can be used.

[0042] For example, the connecting hose 7 can be configured as a polyurethane hose, a nylon hose, etc.

[0043] In some possible implementations, each of the second interfaces 321 may be equipped with a flow regulating valve. Before using the charging gun, the operator can adjust the opening of the flow regulating valve to adjust the flow rate of the cold air entering the first cooling channel 41, so as to ensure that the flow rate of the cold air is compatible with the power of the charging gun.

[0044] In other possible implementations, such as Figure 3 As shown, the flow divider 32 may have a third interface 322, which may be connected to the second cooling channel 42.

[0045] In this way, the cold air generated by the vortex tube 31 can be introduced into the mounting chamber 11 through the third interface 322 to cool the outside of the cable 2.

[0046] In the embodiments of this disclosure, the diverter 32 may have a cavity. The diverter 32 is provided with a first interface, a second interface 321 and a third interface 322, all of which are connected to the cavity. The first interface is connected to the cold air exhaust section 6. In this way, the cold air discharged from the vortex tube 31 can first enter the cavity. Then, the cold air in the cavity will enter the first cooling channel 41 from the second interface 321 and enter the second cooling channel 42 from the third interface 322. This ensures that the cold air can simultaneously dissipate heat to the inside and outside of the cable 2, thereby ensuring the normal use of the charging gun.

[0047] In some possible implementations, when the charging gun has a second cooling channel 42, a first through hole may also be provided on the charging gun housing 1, the first through hole being used to connect the second cooling channel 42 to the outside of the charging gun housing 1.

[0048] In this way, the cold air flowing through the second cooling channel 42 can exchange heat with the outside of the cable 2 and then flow from the first through hole to the outside of the charging gun housing 1, thereby forming a complete cooling circuit.

[0049] It is understandable that multiple first through holes can be provided, and multiple first through holes can be arranged at intervals on the charging gun housing 1 to ensure the gas flow efficiency in the installation chamber 11, thereby improving the heat exchange efficiency between the cold air and the cable 2 in the installation chamber 11.

[0050] For example, the charging gun may have a first wall and a second wall that are arranged opposite to each other. The third interface 322 may be arranged opposite to the first wall, and the first through hole may be arranged on the second wall. In this way, when the cold air enters the second cooling channel 42 through the third interface 322, the cold air will first flow towards the first wall. After being reflected by the first wall, the cold air will flow towards the second wall. During this process, the cold air can exchange heat with the cable 2 and finally flow out of the charging gun housing 1 through the first through hole on the second wall. Thus, the cold air can flow through most of the area of ​​the mounting chamber 11, avoiding uneven local heat exchange in the mounting chamber 11, thereby ensuring the heat exchange efficiency between the cold air and the cable 2.

[0051] In some possible implementations, such as Figure 2 and Figure 3 As shown, the vortex tube 31 may also have a hot gas exhaust section 8, which is used to communicate with the outside of the charging gun housing 1. The charging gun housing 1 is provided with a second through hole and a third through hole. The air inlet 5 passes through the second through hole, and the hot gas exhaust section 8 passes through the third through hole.

[0052] The hot gas generated by the vortex tube 31 can be discharged to the outside of the charging gun housing 1 through the hot gas discharge part 8. The air inlet 5 and the hot gas discharge part 8 can be provided with threads, and the air inlet 5 and the hot gas discharge part 8 can be connected to the charging gun housing 1 by means of threaded connection. In this way, the connection efficiency between the vortex tube 31 and the charging gun housing 1 can be improved.

[0053] It is understandable that the end of the heat exhaust section 8 located outside the charging gun housing 1 can extend toward the side away from the charging gun head, so that the position from which the heat exhaust section 8 is discharged is as far away from the user as possible, or the end of the heat exhaust section 8 located outside the charging gun housing 1 can be connected to a heat dissipation box with a cooling fan.

[0054] In addition, a heat insulation film can be provided on the charging gun housing 1, thereby minimizing the risk of the user being harmed by the hot or cold air generated by the vortex tube 31.

[0055] In the embodiments of this disclosure, a first through hole may also be provided on the charging gun housing 1. The first through hole is used to connect the second cooling channel 42 with the outside of the charging gun housing 1. The second through hole and the first through hole are the same through hole, and there is a first gap between the hole wall of the second through hole and the air inlet 5.

[0056] In this way, the cold air in the mounting chamber 11 can flow out through the first gap after exchanging heat with the cable 2, so as to realize the circulation of gas inside and outside the mounting chamber 11 and ensure the circulation of gas inside and outside the mounting chamber 11.

[0057] In some possible implementations, the third through hole and the first through hole can be the same through hole, and there is a second gap between the wall of the third through hole and the hot gas exhaust part 8.

[0058] In this way, the cold air in the mounting chamber 11 can flow out through the second gap after exchanging heat with the cable 2, so as to realize the circulation of gas inside and outside the mounting chamber 11 and ensure the circulation of gas inside and outside the mounting chamber 11.

[0059] In some other possible embodiments, the wall of the second through hole has a first gap with the air inlet 5, and the wall of the third through hole has a second gap with the hot air outlet 8.

[0060] This improves the efficiency of gas circulation inside and outside the installation chamber 11, thereby ensuring the cooling effect of the cold air on the outside of the cable 2.

[0061] In embodiments of this disclosure, such as Figures 1 to 3 As shown, the charging gun may also include a connection terminal 9, the first end of which passes through the charging gun housing 1 and is electrically connected to the cable 2, and the second end of which is used to electrically connect to the device to be charged.

[0062] The first end of the connecting terminal 9 can be connected to the cable 2 by welding. In other words, the first end of the connecting terminal 9 can also be located inside the tubular body 21. In this way, the cold air in the first cooling channel 41 can dissipate heat to the first end of the connecting terminal 9 while cooling the conductor wire 22, thereby improving the cooling efficiency of the eddy current tube 31 and ensuring the normal use of the charging gun.

[0063] When the charging gun is working, the cold air generated by the vortex tube 31 enters the first cooling channel 41 and flows along the tubular body 21 toward both ends of the tubular body 21. One end of the tubular body 21 is connected to the connecting terminal 9, and the other end is connected to the charging pile of, for example, the charging device. Thus, the cold air generated by the vortex tube 31 can cool the conductor wire 22 and the connecting terminal 9 at the same time, and the gas after exchanging heat with the conductor wire 22 and the connecting terminal 9 can be discharged from the charging pile side to form a complete cooling circuit.

[0064] It is understandable that since the connection terminal 9 is located close to the charging gun housing 1, the eddy current tube 31 is located in the charging gun housing 1, which can also shorten the distance that the cold air flows to one end of the connection terminal 9. Thus, the cooling effect of the cold air on the connection terminal 9 can also be guaranteed.

[0065] A second aspect of this disclosure provides a charging device, including the aforementioned charging gun. It should be noted that this charging device possesses all the beneficial effects of the aforementioned charging gun, and this disclosure will not limit it further.

[0066] In embodiments of this disclosure, the charging device may further include a compressed gas supply device, with the air inlet 5 connected to the compressed gas supply device.

[0067] The compressed gas supply device can be configured as a compressor.

[0068] In summary, this disclosure exemplarily illustrates the use of a charging gun.

[0069] When the charging gun is in use, the compressor inputs compressed gas into the vortex tube 31 through the air intake 5. The compressed gas generates cold air and hot air in the vortex tube 31. The hot air is discharged from the charging gun housing 1 through the hot air exhaust 8, while the cold air enters the diverter 32 through the cold air exhaust 6 and the connecting hose 7. The cold air in the diverter 32 is split into two paths and discharged from the second interface 321 and the third interface 322 respectively. The cold air discharged from the second interface 321 enters the first cooling channel 41, that is, the gap between the tubular body 21 and the conductor wire 22, and flows in the first cooling channel 41 to dissipate heat from the conductor wire 22 and the connecting terminal 9. The cold air that has undergone heat exchange in the tubular body 21 is finally discharged from the charging pile side. The cold air discharged from the third interface 322 enters the second cooling channel 42 to cool the outer surface of the cable 2. The cold air that has undergone heat exchange in the second cooling channel 42 is finally discharged from the first through hole on the charging gun housing 1.

[0070] Based on this, the cooling system can simultaneously dissipate heat from the inside and outside of the cable 2 as well as the terminals. The eddy current tube 31 is installed in the mounting chamber 11, which can also shorten the distance between the eddy current tube 31 and the cooling channel 4, thereby reducing the energy loss of the cold air flowing into the cooling channel 4, thus improving the heat dissipation efficiency of the cold air on the cable 2 and ensuring the normal use of the charging gun.

[0071] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0072] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0073] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
