根據本發明的一可選實施例，冷卻系統包括：空調冷卻系統20和電動車輛的電池或高壓電器的冷卻系統，充電裝置100設置的管路可以為兩個，二管路分別為第一冷卻管路24和第二冷卻管路50，第一冷卻管路24用於冷卻接線端子11，接線端子11中開設有流路以形成第一冷卻管路24；第二冷卻管路50用於冷卻充電線束12。According to an alternative embodiment of the present invention, the cooling system includes: an air-conditioning cooling system 20 and a cooling system for batteries or high-voltage electrical appliances of an electric vehicle. The charging device 100 may be provided with two pipes, and the two pipes are respectively the first cooling The pipeline 24 and the second cooling pipeline 50, the first cooling pipeline 24 is used for cooling the terminal 11, the terminal 11 is provided with a flow path to form the first cooling pipeline 24; the second cooling pipeline 50 is used for cooling Charge harness 12

空調冷卻系統20與第一冷卻管路24和第二冷卻管路50中的一者相連且電動車輛的電池或高壓電器的冷卻系統與第一冷卻管路24和第二冷卻管路50中的另一者相連以向第一冷卻管路24和第二冷卻管路50提供冷卻液。The air conditioning cooling system 20 is connected to one of the first cooling pipe 24 and the second cooling pipe 50 and the cooling system of the battery or high-voltage electrical appliance of the electric vehicle is connected to the first cooling pipe 24 and the second cooling pipe 50. The other is connected to supply cooling liquid to the first cooling line 24 and the second cooling line 50.

下面以空調冷卻系統20與第一冷卻管路24相連且電動車輛的電池或高壓電器的冷卻系統與第二冷卻管路50相連為例進行說明。In the following, the air-conditioning cooling system 20 is connected to the first cooling pipe 24 and the battery or high-voltage electrical appliance cooling system of the electric vehicle is connected to the second cooling pipe 50 as an example for description.

如第1圖所示，空調冷卻系統20包括：壓縮機21、冷凝器22、閥體和蒸發器23，壓縮機21、冷凝器22、閥體和和蒸發器23串聯設置，第一冷卻管路24設置在充電連接件10內，而且第一冷卻管路24與蒸發器23相連。也就是說，在充電連接件10處設置第一冷卻管路24，然後第一冷卻管路24參與到冷媒的迴圈中，這樣位於第一冷卻管路24內的低溫冷媒可以有效與充電連接件10進行換熱，從而可以保證充電連接件10的工作可靠性。As shown in FIG. 1, the air-conditioning cooling system 20 includes: a compressor 21, a condenser 22, a valve body and an evaporator 23, the compressor 21, the condenser 22, a valve body and the evaporator 23 are arranged in series, and the first cooling pipe The path 24 is provided in the charging connector 10, and the first cooling pipe 24 is connected to the evaporator 23. That is, the first cooling pipe 24 is provided at the charging connector 10, and then the first cooling pipe 24 participates in the circulation of the refrigerant, so that the low-temperature refrigerant located in the first cooling pipe 24 can be effectively connected to the charging The piece 10 performs heat exchange, so that the working reliability of the charging connection piece 10 can be ensured.

可選地，第一冷卻管路24可以與蒸發器23串聯。這樣經過蒸發器23後的冷媒可以繼續流經第一冷卻管路24，並且在第一冷卻管路24處於充電連接件10進行換熱，從而可以帶走充電連接件10的熱量。Alternatively, the first cooling line 24 may be connected in series with the evaporator 23. In this way, the refrigerant after passing through the evaporator 23 can continue to flow through the first cooling pipe 24, and the first cooling pipe 24 is at the charging connector 10 for heat exchange, so that the heat of the charging connector 10 can be taken away.

另一種可選地，如第1圖所示，第一冷卻管路24與蒸發器23的至少一部分管路並聯。也就是說，第一冷卻管路24與蒸發器23的至少一部分管路採用並聯形式，這樣第一冷卻管路24可以更好地降低充電連接件10的工作溫度。而且，第一冷卻管路24可以與蒸發器23的一部分管路並聯，也可以與整個蒸發器23並聯。Alternatively, as shown in FIG. 1, the first cooling pipe 24 is connected in parallel with at least a part of the pipe of the evaporator 23. In other words, the first cooling line 24 and at least a part of the evaporator 23 are connected in parallel, so that the first cooling line 24 can better reduce the working temperature of the charging connector 10. Furthermore, the first cooling line 24 may be connected in parallel with a part of the line of the evaporator 23 or in parallel with the entire evaporator 23.

再一種可選地，蒸發器23的至少一部分構成第一冷卻管路24，這樣第一冷卻管路24可以更好地降低充電連接件10的工作溫度。In another alternative, at least a part of the evaporator 23 constitutes the first cooling line 24, so that the first cooling line 24 can better reduce the working temperature of the charging connection 10.

其中，如第2圖所示，第一冷卻管路24鄰近接線端子11設置。由此，第一冷卻管路24可以直接與接線端子11進行換熱，從而可以直接帶走接線端子11所產生的熱量，進而可以有效降低充電連接件10的工作溫度。As shown in FIG. 2, the first cooling pipe 24 is provided adjacent to the terminal 11. As a result, the first cooling pipe 24 can directly exchange heat with the terminal 11, so that the heat generated by the terminal 11 can be directly taken away, and the working temperature of the charging connector 10 can be effectively reduced.

可選地，第一冷卻管路24穿過接線端子11。例如，接線端子11可以為兩個，第一冷卻管路24穿過從殼體14的一側伸入到殼體14內部，然後橫向穿過二接線端子11，再從殼體14的另一側伸出，這樣第一冷卻管路24可以直接與接線端子11接觸，而且可以有效帶走接線端子11的熱量，而且如此設置的第一冷卻管路24結構簡單。Optionally, the first cooling pipe 24 passes through the terminal 11. For example, there may be two connection terminals 11. The first cooling pipe 24 extends from one side of the housing 14 into the inside of the housing 14, and then passes laterally through the two connection terminals 11, and then from the other of the housing 14. The side is extended, so that the first cooling pipe 24 can directly contact the terminal 11 and can effectively take away the heat of the terminal 11, and the first cooling pipe 24 thus provided has a simple structure.

另一種可選地，如第2圖所示，第一冷卻管路24可以套設在接線端子11上。採用套設的形式可以有效增加第一冷卻管路24和接線端子11之間的接觸面積，從而可以更好地降低接線端子11的工作溫度。Alternatively, as shown in FIG. 2, the first cooling pipe 24 may be sleeved on the terminal 11. The form of nesting can effectively increase the contact area between the first cooling pipe 24 and the terminal 11 so that the working temperature of the terminal 11 can be better reduced.

進一步地，接線端子11為兩個，第一冷卻管路24彎折設置以套設二接線端子11。也就是說，一第一冷卻管路24可以同時套設在二接線端子11上這樣可以省略一第一冷卻管路24，而且可以使得第一冷卻管路24佈置簡單，二接線端子11換熱均勻。Further, there are two connection terminals 11, and the first cooling pipeline 24 is bent to cover the two connection terminals 11. That is to say, a first cooling line 24 can be sleeved on the two terminals 11 at the same time so that a first cooling line 24 can be omitted, and the first cooling line 24 can be arranged simply, and the two terminals 11 exchange heat Evenly.

根據本發明的另一可選實施例，如第3圖和第4圖所示，冷卻系統包括：空調冷卻系統20，冷卻管路設置在殼體14、接線端子11和充電線束12中的至少一個上。也就是說，冷卻管路可以選擇性地冷卻殼體14、接線端子11和充電線束12中的至少一個，這樣也可以有效降低充電連接件10的工作溫度。其中，在本實施例中，冷卻系統20可以不包括蒸發器23，這樣冷卻系統20可以省略蒸發器23，從而可以進一步地簡化冷卻系統20的結構，可以降低冷卻系統20的成本。接線端子11和充電線束12至少一個的冷卻管路以構成該空調冷卻系統的蒸發器的至少一部分。According to another optional embodiment of the present invention, as shown in FIG. 3 and FIG. 4, the cooling system includes: an air conditioning cooling system 20, and a cooling pipe is provided in at least one of the housing 14, the terminal 11 and the charging harness 12 One on. That is to say, the cooling line can selectively cool at least one of the housing 14, the connection terminal 11 and the charging harness 12, which can also effectively reduce the working temperature of the charging connector 10. In this embodiment, the cooling system 20 may not include the evaporator 23, so that the cooling system 20 can omit the evaporator 23, thereby further simplifying the structure of the cooling system 20 and reducing the cost of the cooling system 20. The cooling line of at least one of the connection terminal 11 and the charging harness 12 constitutes at least a part of the evaporator of the air conditioning cooling system.

可選地，如第3圖和第4圖所示，冷卻管路可以為複數，冷卻管路包括：第一冷卻管路24，第一冷卻管路24設置在殼體14內，或者說，殼體14上設有流道形成第一冷卻管路24。殼體14可以起到保護第一冷卻管路24的作用，而且第一冷卻管路24在殼體14內可以與接線端子11有效換熱，從而可以更好地帶走接線端子11的熱量，可以有效降低接線端子11的工作溫度。Optionally, as shown in FIG. 3 and FIG. 4, the cooling pipeline may be plural. The cooling pipeline includes: a first cooling pipeline 24, and the first cooling pipeline 24 is disposed in the housing 14, or, The casing 14 is provided with a flow passage to form a first cooling pipe 24. The housing 14 can protect the first cooling pipe 24, and the first cooling pipe 24 can effectively exchange heat with the terminal 11 in the housing 14, so that the heat of the terminal 11 can be better taken away. The working temperature of the terminal 11 can be effectively reduced.

可選地，第一冷卻管路24穿過接線端子11。例如，接線端子11可以為兩個，第一冷卻管路24穿過從殼體14的一側伸入到殼體14內部，然後橫向穿過二接線端子11，再從殼體14的另一側伸出，這樣第一冷卻管路24可以直接與接線端子11接觸，而且可以有效帶走接線端子11的熱量，而且如此設置的第一冷卻管路24結構簡單。Optionally, the first cooling pipe 24 passes through the terminal 11. For example, there may be two connection terminals 11. The first cooling pipe 24 extends from one side of the housing 14 into the inside of the housing 14, and then passes laterally through the two connection terminals 11, and then from the other of the housing 14. The side is extended, so that the first cooling pipe 24 can directly contact the terminal 11 and can effectively take away the heat of the terminal 11, and the first cooling pipe 24 thus provided has a simple structure.

另一種可選地，如第3圖和第4圖所示，第一冷卻管路24可以套設在接線端子11上。採用套設的形式可以有效增加第一冷卻管路24和接線端子11之間的接觸面積，從而可以更好地降低接線端子11的工作溫度。Alternatively, as shown in FIGS. 3 and 4, the first cooling pipe 24 may be sleeved on the terminal 11. The form of nesting can effectively increase the contact area between the first cooling pipe 24 and the terminal 11 so that the working temperature of the terminal 11 can be better reduced.

進一步地，接線端子11為兩個，第一冷卻管路24彎折設置以套設二接線端子11。也就是說，一第一冷卻管路24可以同時套設在二接線端子11上這樣可以省略一第一冷卻管路24，而且可以使得第一冷卻管路24佈置簡單，二接線端子11換熱均勻。Further, there are two connection terminals 11, and the first cooling pipeline 24 is bent to cover the two connection terminals 11. That is to say, a first cooling line 24 can be sleeved on the two terminals 11 at the same time so that a first cooling line 24 can be omitted, and the first cooling line 24 can be arranged simply, and the two terminals 11 exchange heat Evenly.

還有，如第3圖和第4圖所示，冷卻管路還可以包括：第二冷卻管路50，第二冷卻管路50套設在充電線束12上。由此，第二冷卻管路50可以用於冷卻充電線束12，從而可以有效降低充電線束12的溫度，可以進一步地降低接線端子11的工作溫度。In addition, as shown in FIGS. 3 and 4, the cooling pipe may further include: a second cooling pipe 50, and the second cooling pipe 50 is sleeved on the charging harness 12. Thus, the second cooling line 50 can be used to cool the charging harness 12, so that the temperature of the charging harness 12 can be effectively reduced, and the working temperature of the terminal 11 can be further reduced.

冷凝器22和第二冷卻管路50之間以及第二冷卻管路50和壓縮機21之間分別連接有連接管路，連接管路的直徑小於冷卻管路的直徑。壓縮機21將氣態的冷媒壓縮為高溫高壓的氣態冷媒，然後送到冷凝器22散熱後成為常溫高壓的液態冷媒，然後進入連接管路後空間突然增大，壓力減少，液態的冷媒就會汽化，變成氣態低溫的冷媒，從而吸收大量的熱量，大量的熱量來自充電線束12。其中，第一冷卻管路24的直徑也大於連接管路的直徑。Connecting pipes are connected between the condenser 22 and the second cooling pipe 50 and between the second cooling pipe 50 and the compressor 21, and the diameter of the connecting pipe is smaller than the diameter of the cooling pipe. The compressor 21 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser 22 to dissipate heat to become a normal-temperature and high-pressure liquid refrigerant. After entering the connecting pipe, the space suddenly increases and the pressure decreases, and the liquid refrigerant will vaporize. , Becomes a gaseous low-temperature refrigerant, thereby absorbing a large amount of heat, and a large amount of heat comes from the charging harness 12. The diameter of the first cooling pipe 24 is also larger than the diameter of the connecting pipe.

需要說明的是，如第4圖所示，第一冷卻管路24和第二冷卻管路50之間可以串聯連接，如第3圖所示，第一冷卻管路24和第二冷卻管路50之間可以並聯連接。It should be noted that, as shown in FIG. 4, the first cooling pipe 24 and the second cooling pipe 50 may be connected in series, as shown in FIG. 3, the first cooling pipe 24 and the second cooling pipe 50 can be connected in parallel.

It can be understood that the difference between this embodiment and the above-mentioned embodiment is that the second cooling line 50 no longer passes the refrigerant, but passes the cooling water, and is connected to the liquid storage tank 30 and the pump body 40. In this way, when the charging connector 10 is working, the pump body 40 starts to work, pumping the cooling water in the liquid storage tank 30 into the second cooling pipe 50, so that the second cooling pipe 50 can cool the charging wire harness outside the charging wire harness 12 12, so that the operating temperature of the charging harness 12 can be better reduced. It should be noted that the second cooling line 50 can also be used to cool the terminal 11 and/or the housing 14, that is to say, the second cooling line 50 can be used to connect the terminal 11, the charging cable 12 and the housing At least one of 14. In the following, the description will be continued by taking the second cooling pipe 50 for cooling the charging harness as an example.

另外，在充電連接件10完成充電之後，泵體40還可以將第二冷卻管路50內的冷卻水泵入儲液箱30內，這樣可以避免第二冷卻管路50內的冷卻水洩漏，從而可以保證充電裝置100的使用可靠性。In addition, after the charging connector 10 is charged, the pump body 40 can also pump the cooling water in the second cooling line 50 into the liquid storage tank 30, which can prevent the cooling water in the second cooling line 50 from leaking, thereby The use reliability of the charging device 100 can be guaranteed.

可選地，充電線束12的外表面設置有防水層。防水層的設置可以避免冷卻水洩漏到充電線束12內部，這樣可以保證充電線束12的使用安全性，可以避免發生安全事故。Optionally, the outer surface of the charging harness 12 is provided with a waterproof layer. The provision of the waterproof layer can prevent the cooling water from leaking into the charging harness 12, so that the safety of the charging harness 12 can be ensured and a safety accident can be avoided.

還有，如第6圖所示，第二冷卻管路50的兩端設置有密封套51，密封套51套設在充電線束12上。由於第二冷卻管路50套設在充電線束12上，通過在其兩端設置密封套51，可以有效避免冷卻液從第二冷卻管路50的兩端洩漏，從而可以保證第二冷卻管路50的密封性，可以保證充電裝置100的使用安全性。 As shown in FIG. 6, the second cooling pipe 50 is provided with sealing sleeves 51 at both ends, and the sealing sleeves 51 are sleeved on the charging harness 12. Since the second cooling pipe 50 is sleeved on the charging harness 12, by providing the sealing sleeves 51 at both ends thereof, the leakage of the cooling liquid from both ends of the second cooling pipe 50 can be effectively avoided, thereby ensuring the second cooling pipe The tightness of 50 can ensure the safety of the charging device 100 in use.

In other words, the cooling water can flow through the driving motor 60 and the motor controller 61 through the connecting pipe, so that the cooling water can effectively take away the heat at the driving motor 60 and the motor controller 61. In other words, the cooling functions of the driving motor 60, the motor controller 61, and the charging harness 12 are all controlled and provided by the pump body 40 and the liquid storage tank 30, so that the cooling system 20 can be effectively simplified.

還有，如第6圖所示，充電裝置100還可以包括：冷卻風扇90，冷卻風扇90鄰近泵體40設置。冷卻風扇90可以有效增強冷卻水與外界環境的換熱能力，從而可以為充電線束12、驅動電動機60和電動機控制器61提供溫度低的冷卻水。 In addition, as shown in FIG. 6, the charging device 100 may further include a cooling fan 90 that is disposed adjacent to the pump body 40.

可選地，充電裝置100還包括：控制閥(圖未示出)，控制閥設置在泵體40和第二冷卻管路50之間。控制閥可以用於切斷泵體40和第二冷卻管路50，這樣在第二冷卻管路50中充滿冷卻水後，控制閥關閉，從而可以使得第二冷卻管路50保持充滿狀態，在充電結束後，控制閥打開，允許泵體40將第二冷卻管路50內的冷卻水抽走，抽走完成後，控制閥關閉。 Optionally, the charging device 100 further includes: a control valve (not shown), the control valve is disposed between the pump body 40 and the second cooling line 50. The control valve can be used to cut off the pump body 40 and the second cooling line 50, so that after the second cooling line 50 is filled with cooling water, the control valve is closed, so that the second cooling line 50 can be kept full. After the charging is completed, the control valve is opened, allowing the pump body 40 to draw the cooling water in the second cooling line 50, and after the pumping is completed, the control valve is closed.

具體地，控制閥可以為兩個，二控制閥可以分別設置在第二冷卻管路50的進口和出口。 Specifically, there may be two control valves, and the two control valves may be respectively provided at the inlet and outlet of the second cooling line 50.

進一步地，充電裝置100還可以包括：控制器和溫度感測器，溫度感測器用於檢測充電線束12的溫度，控制器分別與溫度感測器和控制閥電連接以在溫度感測器檢測的溫度值達到預定值時控制泵體40工作和控制閥打開。這樣控制閥和泵體40之間可以同步工作，例如，泵體40工作時，控制閥打開，泵體40停止工作時，控制閥關閉。這樣可以保證冷卻系統20的工作可靠性。 Further, the charging device 100 may further include: a controller and a temperature sensor, the temperature sensor is used to detect the temperature of the charging harness 12, and the controller is electrically connected to the temperature sensor and the control valve to detect the temperature sensor When the temperature value reaches a predetermined value, the pump body 40 is controlled to work and the control valve is opened. In this way, the control valve and the pump body 40 can work synchronously. For example, when the pump body 40 works, the control valve opens, and when the pump body 40 stops working, the control valve closes. In this way, the operational reliability of the cooling system 20 can be ensured.

較佳地，溫度感測器為複數，而且複數溫度感測器在充電線束12的長度方向上間隔開設置。複數溫度感測器的設置可以有利於提高控制器的控制精准性。 Preferably, the temperature sensors are plural, and the plural temperature sensors are arranged at intervals in the length direction of the charging harness 12.

另外，在存在壓縮機21的冷卻系統20中，控制器還可以與壓縮機21電連接以在溫度感測器檢測的溫度值達到預定值時控制壓縮機21工作。由此，可以合理控制冷卻系統20，從而可以適時地控制冷卻系統20工作，從而可以保證充電連接件10的工作溫度適宜。 In addition, in the cooling system 20 where the compressor 21 is present, the controller may also be electrically connected to the compressor 21 to control the operation of the compressor 21 when the temperature value detected by the temperature sensor reaches a predetermined value. Thus, the cooling system 20 can be reasonably controlled, so that the operation of the cooling system 20 can be controlled in a timely manner, so that the working temperature of the charging connector 10 can be ensured to be appropriate.

The air supply member 25 is disposed in the air cooling channel 73, and the outlet of the air cooling channel 73 communicates with the cooling cabin 70.

Alternatively, the blower 25 may be an axial fan. The axial fan can facilitate the air supply to the interior of the cooling cabin 70, and the structure of the axial fan is simple.

具體地，如第8圖所示，前固定座71包括：底壁71a和周壁71b，充電連接件10固定在底壁71a上，周壁71b上設置有出風口71c。也就是說，送風件25吹向冷卻艙70內的冷風可以從出風口71c吹出，這樣吹出後的冷風可以再次與充電連接件10接觸，從而可以更好地帶走充電連接件10的熱量。 Specifically, as shown in FIG. 8, the front fixing base 71 includes a bottom wall 71a and a peripheral wall 71b, and the charging connector 10 is fixed on the bottom wall 71a, and an air outlet 71c is provided on the peripheral wall 71b. That is to say, the cold wind blown into the cooling compartment 70 by the blowing member 25 can be blown out from the air outlet 71c, so that the blown cold wind can come into contact with the charging connector 10 again, so that the heat of the charging connector 10 can be better taken away.

其中，如第10圖所示，充電連接件10可以包括：殼體14和接線端子11，接線端子11固定在殼體14內，殼體14的內周形成有通風孔15。由此，在充電連接件10與充電槍對接時，冷風通過進風口71d進入冷卻艙70，然後冷風從出風口71c流出，然後從出風口71c吹出的冷風可以流過通風孔15，將充電連接件10包裹住，這樣冷風不僅可以冷卻充電連接件10，還可以冷卻充電槍，從而可以更好的降低充電連接件10的工作溫度。 As shown in FIG. 10, the charging connector 10 may include a housing 14 and a terminal 11.

That is to say, the air blowing member 25 and the compressor 21 can not work at the same time. For example, when the temperature is low and the charging connector 10 starts to charge, the air blowing member 25 starts to work, which can provide the charging connector 10 with a certain flow of normal temperature Wind, which can slow down the working temperature of the charging connector 10 does not rise. When the temperature of the charging connector 10 rises to a predetermined temperature, the compressor 21 starts to work again, the evaporator 23 first exchanges heat with the air, and then the air and the charging connector 10 heat exchange, so that the working temperature of the charging connector 10 can be quickly reduced.
