Specific embodiments

[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: a split-type DC charging pile host, including a chassis 1, and a cooling mechanism 5 is fixedly connected to the upper end of the chassis 1. The cooling mechanism 5 can cool the charging pile host during operation to prevent the equipment from overheating. In the upper part of the inner cavity of the chassis 1, there is a charging module group, which is composed of a plurality of charging modules 4 arranged in an array. The charging module 4 is a prior art. There is an interface 41 at its front end for connecting the incoming and outgoing coolant. The charging module 4 can convert the alternating current in the power grid into direct current for charging the power battery of new energy vehicles. During the processes of rectification and voltage transformation, a part of the electrical energy will be converted into heat. Therefore, the charging module 4 is the component that generates the most heat in the entire charging pile. Installing multiple charging modules 4 in the DC charging pile is to meet different power requirements and improve the charging efficiency. The multiple charging modules 4 are all fixedly installed in the chassis 1 through brackets.

[0028] Furthermore, a regulation module 2 is fixedly installed on the right side of the lower part of the inner cavity of the chassis 1. The regulation module 2 is a prior art and can precisely control the current and voltage output by the charging module 4 to meet the charging requirements of different types of electric vehicle batteries. And the regulation module 2 needs to be connected to the charging gun of the split-type charging pile terminal to ensure the charging function of the DC charging pile. A power control module 3 is fixedly installed on the left side of the lower part of the inner cavity of the chassis 1. The power control module 3 is a prior art, and it contains a circuit breaker and an AC contactor inside, which can connect and disconnect the circuit and control the power-on state of the entire charging pile host. In the front part of the inner cavity of the chassis 1, there is also a liquid cooling pipeline 6 for transporting coolant. The liquid cooling pipeline 6 is composed of an outlet pipeline 61 and a return pipeline 62. The outlet pipeline 61 and the return pipeline 62 are respectively used to cooperate with the input and return of coolant when multiple charging modules 4 are working.

[0029] Furthermore, a main board 31 and a power module 32 are provided at the rear end of the power control module 3. Both the main board 31 and the power module 32 are prior arts. The main board 31 plays a role of overall coordination and control in the entire host, and can receive and process signals from various sensors and input signals, including the signals of the regulation module 2, the charging module 4, and the cooling mechanism 5. The power module 32 can convert input voltages of different levels into output voltages suitable for specific electronic devices or systems, that is, convert the 220V AC mains into corresponding DC power for the equipment in the charging pile to operate.

[0030] Specifically, as Figures 4-6As shown in the figure, the cooling mechanism 5 includes a chiller frame 51 and an electronic water pump 52. The chiller frame 51 is fixedly installed at the upper end of the chassis 1. There are two cooling fans 55 at the upper end of the chiller frame 51, and a heat dissipation component 54 is provided at the lower end of the chiller frame 51. A heat exchanger is installed inside the heat dissipation component 54. A heat exchanger is a device used to transfer heat from one fluid to another fluid, and its purpose is to achieve heat exchange. The electronic water pump 52 is fixedly installed on the left side of the upper end of the chassis 1. An electric control box 53 for controlling the operation of the electronic water pump 52 and the cooling fans 55 is also fixedly installed on the right side of the upper end of the chassis 1. There are lifting rings 56 at the four corners of the upper end of the chiller frame 51. A lifting ring 56 is a commonly used mechanical connection part that can penetrate into lifting tools such as hooks and slings, so as to realize the lifting operation of the main body of this charging pile.

[0031] Furthermore, an output pipeline 521 is fixedly installed at the output end of the electronic water pump 52, and an input pipeline 522 is fixedly installed at the input end of the electronic water pump 52. The outer surface of the input pipeline 522 passes through the inside of the heat dissipation component 54, and the coolant passing through the input pipeline 522 is cooled under the cooperation of the heat exchanger and the cooling fans 55.

[0032] As Figure 6 shown in the figure, the liquid outlet pipeline 61 includes a liquid outlet main pipe 611. A plurality of first tower ball valves 612 are provided on both the left and right sides of the outer surface of the liquid outlet main pipe 611. When the charging module 4 at the corresponding work station is not needed, the corresponding first tower ball valve 612 needs to be closed. Liquid outlet branch pipes 613 are provided at one end of the plurality of first tower ball valves 612 away from the liquid outlet main pipe 611.

[0033] Furthermore, the structure and principle of the liquid return pipeline 62 are similar to those of the liquid outlet pipeline 61. The liquid return pipeline 62 includes a liquid return main pipe 621. A plurality of second tower ball valves 622 are provided on both the left and right sides of the outer surface of the liquid return main pipe 621. When the charging module 4 at the corresponding work station is not needed, the corresponding second tower ball valve 622 needs to be closed. After closing the corresponding first tower ball valve 612 and the second tower ball valve 622, it is equivalent to isolating the corresponding charging module 4. Liquid return branch pipes 623 are provided at one end of the plurality of second tower ball valves 622 away from the liquid return main pipe 621.

[0034] In addition, the end of the output pipeline 521 away from the electronic water pump 52 is connected to the upper end of the liquid outlet main pipe 611, and the end of the input pipeline 522 away from the electronic water pump 52 is connected to the upper end of the liquid return main pipe 621. And an interface 41 is provided at the front end of each of the plurality of charging modules 4. The same group of liquid return main pipe 621 and second tower ball valves 622 are connected to the corresponding interface 41. Therefore, the flow direction of the coolant in the liquid cooling pipeline 6 is as Figure 6As shown by the arrow in [Figure 0], first, when the electric water pump 52 operates, it will transport the coolant to the main liquid outlet pipe 611 through the output pipeline 521. During the downward transportation process of the coolant in the main liquid outlet pipe 611, it will enter each liquid outlet branch pipe 613. When the coolant enters the corresponding charging module 4 from each liquid outlet branch pipe 613, it will cool the charging module 4. After that, the coolant in each charging module 4 will enter the main liquid return pipe 621 through the corresponding liquid return branch pipe 623 and be transported upward. The coolant in the main liquid return pipe 621 will finally enter the input pipeline 522, be cooled when passing through the heat dissipation component 54, and then return to the electric water pump 52 for recycling.

[0035] Furthermore, a third tower ball valve 63 is provided at the lower ends of both the main liquid outlet pipe 611 and the first tower ball valve 612. When the liquid cooling system of this charging pile needs to replace the coolant, the third tower ball valve 63 can be opened to drain the coolant. A mounting rod 64 is fixedly connected between the outer surfaces of the main liquid outlet pipe 611 and the first tower ball valve 612. The mounting rod 64 is fixedly connected to the inner surface of the chassis 1. The mounting rod 64 is used to fix the positions of the main liquid outlet pipe 611 and the main liquid return pipe 621.

[0036] It should be noted that for this split-type DC charging pile host, the number of actually installed charging modules 4 can be selected according to the number of charging pile terminals (i.e., charging bays) that need to be installed actually. For the workstations where the charging modules 4 are not installed, the corresponding first tower ball valve 612 and the second tower ball valve 622 can be closed.

[0037] The working principle of the present utility model is as follows: For this split-type DC charging pile host, during operation, the electric water pump 52 will transport the coolant to the main liquid outlet pipe 611 through the output pipeline 521. During the downward transportation process of the coolant in the main liquid outlet pipe 611, it will enter each liquid outlet branch pipe 613. When the coolant enters the corresponding charging module 4 from each liquid outlet branch pipe 613, it will cool the charging module 4. After that, the coolant in each charging module 4 will enter the main liquid return pipe 621 through the corresponding liquid return branch pipe 623 and be transported upward. The coolant in the main liquid return pipe 621 will finally enter the input pipeline 522, be cooled when passing through the heat dissipation component 54, and then return to the electric water pump 52 for recycling.
