[0002] At present, the heat dissipation method of new energy vehicle charging piles is mainly air cooling. The air cooling method has the disadvantages of high charging pile operation noise and low protection level. As new energy vehicles have an increasing demand for power and current of charging piles, the air cooling method cannot meet this demand.

[0003] Existing charging piles generally have a cooling fan installed inside the charging pile. The cooling fan exhausts the air inside the charging pile and draws in the air outside the charging pile, realizing air flow inside and outside the charging pile, thereby achieving the effect of heat dissipation and cooling. However, when the charging pile is charging and running, the air cooling effect is poor and it is difficult to meet the charging requirements of high power and large current. Utility Model Content

[0032] Example 1

[0033] See also Figures 1 to 6 This embodiment provides a charging pile, including: a cabinet 1; a conductive copper busbar 2, arranged in the cabinet 1 and suitable for transmitting electrical energy; a liquid cooling assembly 3, arranged in the cabinet 1 and suitable for providing a cooling medium; a charging gun interface 4, arranged on the cabinet 1 and electrically connected to the conductive copper busbar 2, suitable for connecting a charging gun; the charging gun is connected to the liquid outlet of the liquid cooling assembly 3 through a liquid outlet pipe 6, and the charging gun interface 4 is connected to the liquid inlet of the liquid cooling assembly 3 through a liquid inlet pipe 5.

[0034] It should be noted that the charging gun is connected to the liquid inlet pipe 5 at the charging gun interface 4 through a pipeline.

[0035] In this embodiment, a liquid cooling component 3 is provided in the cabinet 1 to provide a cooling medium. The cooling medium flows out from the liquid outlet of the liquid cooling component 3, passes through the liquid outlet pipe 6, flows through the gun line of the charging gun, and is transported to the charging gun to dissipate heat for the charging gun and its gun line. After the heat is dissipated, the cooling medium returns to the charging gun interface 4 through the pipeline, and then flows back to the liquid cooling component through the liquid inlet pipe 5 at the charging gun interface 4 for circulation cooling. Compared with air cooling, this embodiment uses a liquid cooling component 3 and a liquid outlet pipe 6 to transport the cooling medium, which improves the overall heat dissipation effect, reduces the heat dissipation noise, and improves the user experience. By improving the heat dissipation effect, the charging pile as a whole meets the high-power and high-current charging requirements. In addition, while meeting the heat dissipation requirements, the copper consumption in the charging gun and its gun line can be reduced, making the overall lightweight, thereby effectively reducing the weight of the charging gun and facilitating user operation. In specific applications, the charging pile provided by this embodiment can be adapted to charging equipment with a current of 600A or greater.

[0036] Example 2

[0037] As a further improvement to Example 1, Figure 1 As shown, the liquid outlet pipe 6 includes a DC+ liquid outlet pipe and a DC- liquid outlet pipe; the liquid outlet of the liquid cooling component 3 includes a DC+ liquid outlet and a DC- liquid outlet; one end of the DC+ liquid outlet pipe is connected to the DC+ liquid outlet, and the other end is connected to the charging gun; one end of the DC- liquid outlet pipe is connected to the DC- liquid outlet, and the other end is connected to the charging gun.

[0038] In this embodiment, the number of liquid outlet pipes 6 is increased by two DC+ liquid outlet pipes and DC- liquid outlet pipes, further improving the cooling effect. At the same time, the two DC+ liquid outlet pipes and DC- liquid outlet pipes are directly connected to the charging gun for heat dissipation, thereby improving the heat dissipation effect of the charging gun.

[0039] On the basis of the above embodiment, in a preferred embodiment, as Figure 1 As shown, the liquid inlet pipe 5 includes a DC+ liquid inlet pipe and a DC- liquid inlet pipe; the liquid inlet of the liquid cooling component 3 includes a DC+ liquid inlet and a DC- liquid inlet; one end of the DC+ liquid inlet pipe is connected to the DC+ liquid inlet, and the other end is connected to the charging gun interface 4; one end of the DC- liquid inlet pipe is connected to the DC- liquid inlet, and the other end is connected to the charging gun interface 4; the cooling medium in the charging gun is suitable for flowing back to the DC+ liquid inlet pipe and the DC- liquid inlet pipe through the charging gun interface 4.

[0040] It should be noted that the charging gun is connected to the DC+ liquid inlet pipe and the DC- liquid inlet pipe at the charging gun interface 4 through a pipeline, and the pipeline is connected to the liquid outlet pipe inside the charging gun to facilitate circulation and reflux.

[0041] In this embodiment, by providing a DC+ liquid inlet pipe and a DC- liquid inlet pipe, after the cooling medium completes heat dissipation in the charging gun, it flows through the pipeline to the charging gun interface 4, and then returns to the liquid cooling component 3 through the DC+ liquid inlet pipe and the DC- liquid inlet pipe, thereby increasing the reflux speed of the cooling medium, improving the cooling medium's return to the liquid cooling component 3 for circulating heat dissipation, improving the circulation efficiency of the cooling medium, and thereby improving the cooling effect.

[0042] On the basis of the above embodiment, in a preferred embodiment, as Figure 2 and Figure 3 As shown, the liquid cooling component 3 includes an oil pot assembly 31, a heat dissipation device and an oil pump 32 which are connected in sequence through pipelines along the conveying direction of the cooling medium; the liquid outlet of the liquid cooling component 3 is arranged on the oil pump 32; and the liquid inlet of the liquid cooling component 3 is arranged on the oil pot assembly 31.

[0043] In this embodiment, the cooling medium is transported in the liquid cooling component 3 by completing the oil pot assembly 31 to store the cooling medium and recover the cooled cooling medium, and then transported to the heat dissipation device for heat dissipation, and then the oil pump 32 outputs it through the liquid outlet for cooling, so as to complete the cooling cycle.

[0044] On the basis of the above embodiment, in a preferred embodiment, as Figure 2 and Figure 3 As shown, the heat dissipation device includes a heat exchanger 33 and a heat dissipation fan 34; the liquid inlet end of the heat exchanger 33 is connected to the oil pot assembly 31, and the liquid outlet end of the heat exchanger 33 is connected to the oil pump 32; the heat dissipation fan 34 is arranged on one side of the heat exchanger 33, which is suitable for improving the heat dissipation effect of the heat exchanger 33.

[0045] In this embodiment, a heat exchanger 33 is provided to exchange heat for the cooling medium, which facilitates circulating heat dissipation. At the same time, a cooling fan 34 is added to dissipate heat for the heat exchanger 33. At the same time, the cooling fan 34 can also dissipate heat inside the cabinet 1, further improving the heat dissipation effect and ensuring the cooling efficiency of the cooling medium, so that it can meet the charging requirements of high power and large current.

[0046] On the basis of the above embodiment, in a preferred embodiment, as Figure 2 and Figure 3 As shown, the liquid cooling component 3 also includes a control component 35; a liquid inlet temperature sensor is provided at the liquid inlet of the liquid cooling component 3, and a liquid outlet temperature sensor is provided at the liquid outlet of the liquid cooling component 3; the control component 35 is communicatively connected with the liquid inlet temperature sensor, the liquid outlet temperature sensor, the cooling fan 34 and the oil pump 32.

[0047] In this embodiment, the cooling fan 34 and the oil pump 32 are controlled by setting a control component 35, and the temperatures of the liquid inlet and the liquid outlet are collected and compared and analyzed. The target speed of the cooling fan and the oil pump 32 can be obtained by program setting using the existing control algorithm, and then the cooling fan and the oil pump 32 are controlled to maintain a suitable speed, thereby ensuring the heat dissipation effect and improving the degree of intelligence to adapt to various operating conditions.

[0048] Specifically, the control element 35 may be a controller that can be controlled through program settings.

[0049] On the basis of the above embodiment, in a preferred embodiment, as Figure 2 and Figure 3 As shown, a filter 37 for filtering the cooling medium is provided in the oil pump 32 .

[0050] In this embodiment, a filter 37 is provided in the oil pump 32 to filter the cooling medium (eg, coolant), thereby preventing particulate matter from contaminating the charging gun, reducing maintenance times, and increasing service life.

[0051] On the basis of the above embodiment, in a preferred embodiment, as Figures 4 and 5 As shown, heat dissipation windows 7 are provided on the peripheral side of the cabinet 1 corresponding to the liquid cooling assembly 3 .

[0052] It should be noted that the heat dissipation window 7 is provided with a plurality of through holes.

[0053] In this embodiment, by setting up a heat dissipation window 7 for convection with the outside world, the hot air in the cabinet 1 is discharged for heat dissipation, thereby preventing the temperature increase from affecting the stable operation of the internal equipment. Specifically, multiple heat dissipation windows 7 can be set to improve the heat dissipation effect.

[0054] Specifically, the cooling medium can be selected as dimethyl silicone oil, which improves the heat dissipation effect and has higher stability.

[0055] The specific working principle of the charging pile provided in this embodiment is as follows: when heat dissipation is required, the controller controls the oil pump 32 to start and output the cooling medium in the oil pump 32 assembly through the heat exchanger 33. The cooling medium is then output from the DC+ outlet and DC- outlet on the oil pump 32 through the DC+ outlet pipe and DC- outlet pipe, and flows through the gun line of the charging gun to the charging gun for heat dissipation, thereby dissipating heat from the charging gun and its gun line. After heat dissipation, the cooling medium returns to the charging gun interface through the pipeline. The cooling medium then returns to the oil pump 32 assembly through the DC+ inlet pipe and DC- inlet pipe at the charging gun interface 4, so as to be cooled again by the heat exchanger 33 and the heat dissipation fan and then circulates to dissipate heat, thereby improving the heat dissipation effect. In this process, the controller compares and analyzes the temperatures of the inlet and outlet, and can use the existing control algorithm to obtain the target speed of the heat dissipation fan and the oil pump 32 through program setting, and then controls the heat dissipation fan and the oil pump 32 to maintain them at an appropriate speed, thereby ensuring the heat dissipation effect, improving the degree of intelligence, and adapting to various operating conditions. Compared with the use of air cooling alone, this embodiment uses a liquid cooling component 3 and a liquid outlet pipe 6 to transport the cooling medium, which improves the overall heat dissipation effect, reduces heat dissipation noise, and improves the user experience. By improving the heat dissipation effect, the charging pile as a whole meets the high-power and high-current charging requirements, and meets the heat dissipation requirements of the charging pile under high-power and high-current operating conditions. In addition, while meeting the heat dissipation requirements, the copper consumption in the charging gun and its gun wire can be reduced, making the overall weight lighter, convenient for taking the charging gun, and reducing costs. In specific applications, the charging pile provided by this embodiment can be adapted to charging equipment with a current of 600A or greater. This solves the technical problem that the existing charging pile has poor air cooling and heat dissipation effect and is difficult to meet the charging requirements of high power and high current.

[0056] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
