Charging stations are an indispensable supporting facility for the normal use of electric vehicles and one of the key technologies for their development. The charging power of charging stations directly affects the application and development of electric vehicles. With the development of charging station technology, charging speeds are getting faster and charging times are getting shorter, but at the same time, with the increasing power, temperature control of charging stations is becoming more and more difficult.

[0003] Chinese patent application number 202222058441.X discloses a mobile charging pile, which has the advantages of small size and large capacity, but still has the problem of insufficient heat dissipation.

[0004] Therefore, the inventors added a liquid cooling system to it to solve problems such as difficulty in temperature control. Utility Model Content

[0005] To achieve the above objectives, this application proposes a liquid-cooled charging pile, including a support base, a power module, and a control module. The charging pile is equipped with a liquid cooling system, which includes a liquid cooling mechanism, a liquid cooling plate, and a liquid cooling pipeline unit for connecting the liquid cooling plate and the liquid cooling mechanism.

Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0027] like Figures 1 to 3 As shown, a liquid-cooled charging pile includes a support base 1, a power module 3, and a control module 2. The charging pile is equipped with a liquid cooling system, which includes a liquid cooling mechanism 5, a liquid cooling plate 9, and a liquid cooling pipeline unit connecting the liquid cooling plate 9 and the liquid cooling mechanism 5. The liquid cooling mechanism 5 is located on the lower end face of the support base 1 and is configured to pump coolant, allowing the coolant to circulate between the liquid cooling mechanism 5 and the liquid cooling plate 9. An installation groove 4 is provided on the outer wall of the support base 1, and the power module 3 is detachably installed in the installation groove 4. At least one outer end face of the installation groove 4 is provided with the liquid cooling plate 9. A liquid cooling pipeline unit connecting the liquid cooling plate 9 and the liquid cooling mechanism 5 is installed inside the support base 1.

[0028] The liquid cooling piping unit includes: an inlet pipe and an outlet pipe; the inlet pipe and the outlet pipe are respectively located on both sides of the support base 1.

[0029] The inlet and outlet water pipes are set on separate sides to avoid mixing of hot and cold fluids and ensure stable cooling effect; and when one side of the pipe fails, it will not affect the other side, allowing for independent maintenance and reducing maintenance complexity.

[0030] Specifically, the liquid cooling piping unit includes: an inlet pipe and an outlet pipe; the inlet pipe and the outlet pipe are respectively located on both sides of the support base 1.

[0031] Specifically, the water inlet pipeline includes: water inlet 11, water inlet main pipe 12 and water inlet branch pipes 14; the water inlet main pipe 12 is connected to the liquid cooling mechanism 5, and the water inlet main pipe 12 inputs cooling water into the liquid cooling plate 9 through several water inlet branch pipes 14 connected to it.

[0032] Specifically, the water outlet pipeline includes: water outlet 13, water outlet main pipe 15 and water outlet branch pipes; water outlet main pipe 15 is connected to liquid cooling mechanism 5, and water outlet main pipe 15 discharges cooling water from liquid cooling plate 9 through several water outlet branch pipes connected to it.

[0033] The branch pipes collect the hot water from each liquid cooling plate 9 and then flow into the main pipe to avoid hot water stagnation and ensure smooth cooling circulation.

[0034] Furthermore, the temperature of the hot water collected in the main pipe can be centrally monitored. In some feasible embodiments, a temperature sensor can be installed at the main pipe to facilitate real-time monitoring of the heat dissipation system's operating status.

[0035] Specifically, it also includes: a three-way valve 10; the three-way valve 10 is installed at the connection between the main pipe and the branch pipe.

[0036] By adjusting the flow rate of each branch pipe through the three-way valve 10, the cooling water volume can be increased for high-load modules to achieve precise heat dissipation.

[0037] Under a possible operating condition, if a liquid cooling plate 9 fails, the corresponding branch can be shut down to maintain the normal operation of other modules and improve system reliability.

[0038] In one possible embodiment, a check valve can be provided in the three-way valve 10 to avoid the problem of liquid backflow.

[0039] Specifically, the front end of the support base 1 is provided with a charging port 8; the charging port 8 is connected to the power module 3 through the control module 2.

[0040] Specifically, it also includes a heat sink 7; the heat sink 7 is located on the front end face of the support base 1 and close to the opening of the mounting slot 4.

[0041] The liquid cooling plate 9 is responsible for heat dissipation inside the module, while the heat dissipation coil 7 cools the module surface through air convection, forming a synergistic heat dissipation system.

[0042] Specifically, the heat dissipation coil 7 includes multiple cooling pipes, which are located at the front end of the opening of the mounting slot 4. The output and input ends of the cooling pipes are connected to the output and input ends of the liquid cooling mechanism 5, respectively.

[0043] Specifically, the cooling pipes are S-shaped bends.

[0044] Specifically, it also includes pulley unit 6; pulley unit 6 is located at the bottom of support base 1.

[0045] The liquid path of the cooling liquid in this application is as follows: Figure 4 As shown, the cooling mechanism pumps the cooling liquid, which is pumped from the main water inlet pipe 12 and through the three-way valve 10 to each liquid cooling plate 9. The battery module is combined in the form of "liquid cooling plate 9-battery module-liquid cooling plate 9". Through this stacked arrangement, the battery module can obtain a better heat dissipation effect. Moreover, due to its large contact area, the liquid cooling plate 9 has a better heat dissipation effect than the traditional liquid cooling solution of heat pipe.

[0046] Furthermore, the liquid that absorbs heat from the battery module is discharged from the drain outlet of the liquid cooling plate 9, and flows into the main drain pipe from each drain branch pipe, and then re-enters the liquid cooling mechanism 5, realizing the recycling of the cooling liquid.

[0047] In addition, to better adapt to operating conditions, each component is coated with an anti-corrosion coating to form a protective film that prevents corrosive substances such as chlorides.

[0048] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
