There are multiple batteries in the charging stack, so there are also many lines connected to the batteries. Each battery end in the existing charging stack is equipped with a fan to dissipate heat from the battery. The heat dissipation effect is poor, the noise generated during heat dissipation is large, and an air duct needs to be designed for air-cooled heat dissipation. Therefore, the sealing performance of the box is insufficient, and it is vulnerable to the erosion of dust, salt spray, and water vapor, resulting in the attenuation of the equipment life.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the present invention, terms such as "first" and "second" are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "a plurality" is two or more.

[0029] The implementation of the present invention will be described in detail below in conjunction with specific drawings:

[0030] Figure 1 is a front view structure diagram of a liquid-cooled high-power charging pile provided by an embodiment of the present application, Figure 2 is a rear view structure diagram of a liquid-cooled high-power charging pile provided by an embodiment of the present application, as Figure 1 and Figure 2As shown in the figure, the charging stack includes a cabinet body and a heat exchange module 1, a liquid-cooled charging module 2, an AC input module 3, and a DC output module 4 installed in the cabinet body. The liquid-cooled charging module 2 is electrically connected to the AC input module 3 and the DC output module 4 respectively. Alternating current is stored in the liquid-cooled charging module 2 and output through the DC output module 4. The heat exchange module 1 is arranged on the top of the cabinet body to facilitate taking out the heat of the liquid-cooled charging module 2 in the cabinet body. The AC input module 3 and the DC output module 4 are arranged at the bottom of the cabinet body to facilitate users to plug in external power sources and charge electric vehicles.

[0031] The heat exchange module 1 includes two groups of fans 11 and two groups of heat dissipation pipes 12. The fans 11 are arranged on the top of the cabinet body, and the fan blades are higher than the top of the cabinet body to discharge the hot air between the heat dissipation pipes 12 out of the cabinet body, as Figure 5 shown. Each group of heat dissipation pipes 12 is at least five groups of serially connected serpentine coils. The heat dissipation pipes are stacked from top to bottom, increasing the contact area between the heat dissipation pipes and the air, thereby increasing the heat dissipation efficiency.

[0032] The liquid-cooled charging module 2 includes 18 groups of liquid-cooled charging units 21 and a condensation pipe 22. Figure 3 For Figure 1 the front view structural schematic diagram of the liquid-cooled charging unit in Figure 3 shown, the liquid-cooled charging unit 21 includes a liquid inlet 211 and a liquid outlet 212. The condensation pipe 22 sequentially connects the liquid inlets 211 and the liquid outlets 212 of each group of liquid-cooled charging units 21. Condensate is introduced into the condensation pipe 22. At the same time, the condensation pipe 22 is connected to the heat dissipation pipe 12 to form a loop, absorbing and sending out the heat in the liquid-cooled charging unit 21 through the condensate in the condensation pipe 22, reducing the temperature in the liquid-cooled charging unit 21. The liquid-cooled charging unit 21 also includes a heating element (not shown in the figure) and a heat absorption pipe arranged near the heating element. The heat absorption pipe is a serpentine coil, which is arranged inside the liquid-cooled charging unit 21 and is connected to the liquid inlet 211 and the liquid outlet 212 at both ends. Compared with air-cooled heat dissipation, this liquid-cooled heat dissipation can be set near the heating element as needed for easy operation, avoiding the influence of different air volumes caused by space design in air-cooled heat dissipation on the heat dissipation effect.

[0033] The cabinet body includes a first side wall, a second side wall, a third side wall, and a fourth side wall. The first side wall is Figure 1 the side shown in the front view, and the third side wall is Figure 2 the side shown in the rear view. The second side wall and the fourth side wall are the left side wall and the right side wall of the cabinet body respectively.

[0034] The liquid cooling charging unit 21 further includes an AC input terminal 213 and a DC output terminal 124. The AC input terminal 213 and the DC output terminal 124 are arranged on one side facing the third side wall, and the liquid inlet 211 and the liquid outlet 212 are arranged on one side facing the first side wall. This arrangement can separate the electrical part and the condensation part of the liquid cooling charging unit, avoiding circuit damage caused by condensation water leakage.

[0035] A number of heat dissipation holes 13 are provided on the cabinet body corresponding to the heat dissipation pipeline 12. The heat dissipation holes 13 are long holes arranged in parallel, increasing the air circulation between the cabinet body and the outside air. Therefore, the heat exchange module 1 and the liquid cooling charging module 2 are only connected through the heat dissipation pipeline 12. The liquid cooling charging module 2 is a closed structure, and the charging device is not easily eroded by dust, salt spray, and water vapor, extending the service life of the device. The heat exchange module 1 maximizes the contact area with the outside air as much as possible to increase the heat dissipation efficiency. The fan only needs to take out the heat in the heat exchange module 1, so the volume of air blown by the required fan is small, and thus the generated noise is small. While using pure air-cooled heat dissipation, the air duct needs to be redesigned, making the entire charging stack occupy a large space.

[0036] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
