[0002] A charging pile is a device that provides power supply for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). With the development and popularization of electric vehicle technology, charging piles have become an important part of the infrastructure.

[0003] As an important part of the charging pile design, the heat dissipation window is used to ensure the normal operating temperature of the internal electronic components of the charging pile. When the charging pile is working, some electrical components inside will generate heat. After part of the electrical components export the heat through the heat sink, the fan leads the heat to the heat dissipation window and dissipates it, so as to avoid overheating of the internal components.

[0004] However, most charging piles are located outdoors. Especially when charging in hot weather, during the process of the fan of the charging pile taking away the internal heat for heat dissipation, the temperature of the air circulating outside and inside the charging pile is still very high, resulting in a reduction in the cooling and heat dissipation effect. In addition, most of the existing heat dissipation windows of charging piles are open and cannot adjust the temperature according to different situations, and the practicability is relatively single.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Please refer to Figures 1-7, a charging pile heat dissipation window and a charging pile, including a heat dissipation window body 101 installed at the rear end of the charging pile body 1. A heat dissipation shell 2 is fixedly connected to the outer wall on the rear side of the charging pile body 1. A through port 203 is penetrated and opened on the side of the heat dissipation shell 2 close to the charging pile body 1. A temperature monitoring mechanism, a refrigeration mechanism and a heat dissipation mechanism are connected to the middle of the inner wall of the heat dissipation shell 2. The through port 203, the refrigeration mechanism and the heat dissipation mechanism are all matched and aligned with the heat dissipation window body 101. And the refrigeration mechanism is located on the side close to the through port 203 and the heat dissipation window body 101, while the heat dissipation mechanism is located on the side far from the through port 203 and the heat dissipation window body 101. Blowing windows 201 are penetrated and opened on both sides of the heat dissipation shell 2. Sliding ports 204 are opened on the bottom surfaces of the two blowing windows 201. Blowing mechanisms are connected to both sides of the inner wall of the heat dissipation shell 2. Sealing mechanisms are connected to the bottom surfaces of the two blowing mechanisms. And the two blowing mechanisms and the two sealing mechanisms are respectively matched and aligned with the two blowing windows 201.

[0027] As Figures 1 through 7 shown, when the charging pile heat dissipation window in the present utility model is in normal use, various component parts inside the charging pile body 1 will emit a certain degree of heat. At this time, this heat will spread from the heat dissipation window body 101 to the inside of the heat dissipation shell 2. When the temperature monitoring mechanism inside the heat dissipation shell 2 detects that the temperature exceeds the set value, the PLC controller inside the charging pile body 1 (this is prior art, so no detailed description is made for it) starts the refrigeration mechanism and the heat dissipation mechanism. After the refrigeration mechanism is started, it will cool the inside of the heat dissipation shell 2. Then the heat dissipation mechanism will blow the cooled temperature from the through port 203 to the heat dissipation window body 101, and then pass through the heat dissipation window body 101 to cool the component parts that are working inside the charging pile body 1. During the cooling period, the temperature monitoring mechanism keeps working. When it detects that the temperature inside the heat dissipation shell 2 drops below the set value, it stops working to prevent the component parts inside the charging pile body 1 from being damaged due to overcooling.

[0028] In addition, when the charging pile body 1 charges a new energy vehicle, the driver will be located outside the vehicle. However, when it is hot, the driver located outside the vehicle will be roasted by high temperature. At this time, when the driver scans the code to start charging (this is prior art), the driver can manually select whether auxiliary cooling is needed. If needed, the sealing mechanism is opened, and at the same time the blowing mechanism is started. Then the blowing mechanism can blow the cold air inside the heat dissipation shell 2 to the outside through the blowing window 201. At this time, the driver only needs to sit on one side of the heat dissipation shell 2, and can relieve the high temperature through the blowing mechanism, which is more user-friendly.

[0029] As a preferred solution of the present utility model, the temperature monitoring mechanism includes a support block 5 and a temperature sensor 6. One end of the support block 5 is fixedly connected to the side of the inner wall of the heat dissipation shell 2 far from the through port 203, and the other end of the support block 5 is fixedly connected to the temperature sensor 6.

[0030] More specifically, when it is necessary to monitor the temperature inside the heat dissipation shell 2, it is only necessary to monitor the temperature inside the heat dissipation shell 2 in real time through the temperature sensor 6, and when it reaches the temperature at which the refrigeration mechanism and the heat dissipation mechanism can be turned on or off, transmit the electrical signal to the processor and the controller inside the charging pile body 1.

[0031] As a preferred solution of the present utility model, the heat dissipation mechanism includes a heat dissipation motor 8, a heat dissipation fan blade 9 and a motor seat 10. One end of the motor seat 10 is fixedly connected to the side of the inner wall of the heat dissipation shell 2 away from the through port 203, the other end of the motor seat 10 is fixedly connected to the outer wall of the heat dissipation motor 8, the output shaft of the heat dissipation motor 8 is fixedly connected to one end of the central axis of the heat dissipation fan blade 9, the central axis of the heat dissipation fan blade 9 is matched and aligned with the through port 203 and the heat dissipation window 101, and the temperature sensor 6 is located directly below the heat dissipation motor 8.

[0032] More specifically, when it is necessary to blow the cold air generated by the refrigeration mechanism into the through port 203 and the heat dissipation window 101, it is only necessary to turn on the heat dissipation motor 8 through the PLC controller inside the charging pile body 1, and the output shaft of the heat dissipation motor 8 can drive the heat dissipation fan blade 9 to rotate, thereby generating wind and blowing this wind into the through port 203 and the heat dissipation window 101.

[0033] As a preferred solution of the present utility model, the refrigeration mechanism includes a compressor system 7, a partition plate 3 and an evaporator coil 4. The side wall of the partition plate 3 is fixedly connected to the inner wall of the heat dissipation shell 2, the compressor system 7 is located below the partition plate 3, and the outer wall of the compressor system 7 is fixedly connected to the bottom surface of the inner wall of the heat dissipation shell 2. The output end and the input end of the compressor system 7 are respectively fixedly connected to both ends of the evaporator coil 4. The middle section of the evaporator coil 4 passes through the partition plate 3 and is located between the heat dissipation fan blade 9 and the through port 203.

[0034] More specifically, when it is necessary to cool the inside of the heat dissipation shell 2, it is only necessary to turn on the compressor system 7. After the compressor system 7 starts, it will cooperate with the evaporator coil 4 to generate cold air, and thus can complete the cooling of the inside of the heat dissipation shell 2.

[0035] It should be particularly noted here that:

[0036] 1. The compressor system 7 includes, but is not limited to, a compressor, a condenser, an expansion valve / throttle device, a fan, a refrigerant, a liquid storage dryer / filter, etc. Since it is a very mature existing technology, the working principle and the connection relationship of the internal structure will not be described in detail.

[0037] 2. A number of fins can also be provided on the evaporator coil 4 to increase the heat exchange area.

[0038] By setting the partition plate 3, the compressor system 7 can be separated from the evaporator coil 4, the heat dissipation mechanism, etc., so that the heat generated during the operation of the compressor system 7 will not affect the internal temperature of the heat dissipation shell 2.

[0039] As a preferred solution of the present utility model, a ventilation window 202 is penetrated and opened on one side of the heat dissipation shell 2 away from the charging pile body 1. The ventilation window 202 is located below the partition plate 3 and is matched and aligned with the compressor system 7.

[0040] More specifically, by setting the ventilation window 202, it can help the compressor system 7 dissipate heat.

[0041] As a preferred solution of the present utility model, the blowing mechanism includes a cross bracket 11, a blowing motor 12, a blowing fan blade 13 and a support frame 14. One side of the support frame 14 is fixedly connected to the inner wall of the heat dissipation shell 2, and the inner wall of the support frame 14 is matched and aligned with the inner wall of the blowing window 201. The four ends of the cross bracket 11 are fixedly connected to the inner wall of the support frame 14. The outer wall of the blowing motor 12 is fixedly connected to the middle of the cross bracket 11. The output shaft of the blowing motor 12 is fixedly connected to one end of the central axis of the blowing fan blade 13. The bottom surface of the support frame 14 is connected to the sealing mechanism.

[0042] More specifically, when the driver selects the need for auxiliary cooling, at this time, the PLC controller inside the charging pile body 1 turns on the blowing motor 12. The output shaft of the blowing motor 12 drives the blowing fan blade 13 to rotate. When the blowing fan blade 13 rotates, the cold air inside the heat dissipation shell 2 can be blown from the support frame 14 and the blowing window 201 to the outside, thereby assisting the driver in cooling down.

[0043] As a preferred solution of the present utility model, the sealing mechanism includes a sealing plate 15, a lifting mechanism and two moving blocks 16. The sealing plate 15 is located in the sliding port 204, and the outer wall of the sealing plate 15 is slidably connected to the inner wall of the sliding port 204. The side of the sealing plate 15 away from the sliding port 204 is slidably connected to the side wall of the support frame 14. The lower end of the sealing plate 15 close to the support frame 14 is fixedly connected to the two moving blocks 16. The upper end of the lifting mechanism is connected to the two moving blocks 16, and the lower end of the lifting mechanism is connected to the partition plate 3.

[0044] More specifically, when auxiliary cooling is not required, in order to prevent the cold air inside the heat dissipation shell 2 from flowing out through the blowing window 201, at this time, the lifting mechanism can be used to control the moving blocks 16 and the sealing plate 15 to rise, so as to cut off the connection between the support frame 14 and the blowing window 201, thereby preventing cold air from leaking.

[0045] As a preferred embodiment of the present utility model, the lifting mechanism includes a lifting motor 17, a lead screw 18 and a sliding rod 19. The outer wall of the lifting motor 17 is fixedly connected to the bottom surface of the partition plate 3. The output shaft of the lifting motor 17 is fixedly connected to the lower end of the lead screw 18. The other end of the lead screw 18 penetrates through the partition plate 3 and one of the moving blocks 16, and is rotatably connected to the inner wall of the support frame 14. The lead screw 18 is threadedly connected to the penetrated moving block 16. The two ends of the sliding rod 19 are respectively fixedly connected to the support frame 14 and the partition plate 3, and the outer wall of the sliding rod 19 is slidably connected to the inner wall of the other moving block 16.

[0046] More specifically, when it is necessary to control the lifting of the sealing plate 15, only need to turn on the lifting motor 17. After the lifting motor 17 starts, the output shaft can drive the lead screw 18 to rotate. After the lead screw 18 rotates, due to the restriction of the sliding rod 19, the moving block 16 on the surface of the lead screw 18 can move up and down along the lead screw 18, so that the opening and closing of the blowing window 201 can be completed during the lifting process.

[0047] The present utility model also provides a charging pile, including a charging pile body, and further including any one of the aforementioned charging pile heat dissipation windows.

[0048] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
