Description

Technical Field

[0001] The present invention belongs to the technical field of new energy charging equipment, and in particular relates to an installation structure of a new energy charging device. Background Art

[0002] With the rapid development of new energy vehicles and other new energy equipment, in order to meet the charging needs of new energy equipment, the market demand for charging devices with charging piles as the core continues to increase. In the "Guidelines for the Development of Electric Vehicle Charging Infrastructure" issued in 2015, the construction goal is to build 4.8 million charging piles by 2020 to meet the charging needs of 5 million new energy vehicles, including 500,000 public charging piles and 4.3 million private charging piles, with a car-to-pile ratio of basically 1:1. However, the current charging network construction is far behind the plan. By the end of 2023, my country's new energy vehicle ownership will be 20.41 million, with a car-to-pile ratio of 2.4:1, which is a large gap compared with the 1:1 car-to-pile ratio planned in the "Development Guidelines". At the same time, limited by the characteristics of capital nature, among the newly added charging devices in recent years, the incremental private charging piles installed on vehicles account for more than 70%, and the incremental public charging piles account for less than 30%; this leads to that compared with the use of private charging piles, public charging piles are often under greater vehicle-to-pile ratio pressure and higher operating load pressure. In some areas, these charging piles often need to operate continuously for a long time to meet public charging needs. Although the current charging pile devices have tried their best to reduce system pressure by controlling and adjusting the charging method and optimizing the interaction logic between the charging device and the vehicle charging cycle system, the high-load limit operation of most charging devices is still unavoidable. This has led to the installation structure of new energy charging devices in some areas being plagued by heating problems caused by continuous operation for a long time. At the same time, since new energy charging piles are often set up on roads and areas with large traffic volume, the air quality in the environment is poor and the regional temperature is high. Affected by this, the air cooling method commonly used in the current installation structure of new energy charging devices has a small wind force and cannot achieve effective cooling, while a large wind force can easily lead to rapid accumulation of dust and dirt in the internal structure.

DETAILED DESCRIPTION

[0033] The present invention is described in detail below in conjunction with specific embodiments.

[0034] A new energy charging device installation structure of the present invention is mainly used to provide an installation structure for a new energy charging base station such as a new energy charging pile, including but not limited to DC, AC or AC / DC integrated charging piles, etc. This structure is mainly used to provide an installation structure that can ensure that the new energy charging device can achieve effective cooling and heat dissipation during high-load continuous operation in an environment with high traffic volume, while ensuring the isolation and safety of different areas. The interior of the installation structure can be used to install various types of charging units or equipment for traditional new energy charging piles, which are not limited in this application.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, the installation structure of the new energy charging device of the present application mainly includes a temperature control cabinet 2, an electrical cabinet 3, and a circulation component 5;

[0036] The front side of the temperature control cabinet 2 is open, and the electrical cabinet 3 is buckled at the front side of the temperature control cabinet 2; a panel 4 is installed on the front side of the electrical cabinet 3;

[0037] Specific structure such as Figure 3 , Figure 4 , Figure 5 As shown, the circulation assembly 5 includes: a filter box 50 installed at the upper part of the front opening of the electrical cabinet 3, a dust collecting box 51 located at the bottom of the filter box 50, a filter cartridge holder 52 provided inside the filter box 50, and a plurality of filter cartridges 53 installed on the filter cartridge holder 52;

[0038] A partition 30 is provided on the top of the electrical cabinet 3, an air intake fan 31 is installed on the partition 30, and the partition 30 and the front wall of the electrical cabinet 3 form a negative pressure chamber 3a;

[0039] The front side of the filter box 50 is hollowed out to form an air intake passage, and the top of the dust collecting box 51 is open;

[0040] A filter cartridge positioning plate 55 is provided in the middle of the filter cartridge frame 52; the front end surface of the filter cartridge positioning plate 55 and the front half of the filter cartridge frame 52 enclose a diversion chamber 5a, and the rear end surface of the filter cartridge positioning plate 55 and the rear half of the filter cartridge frame 52 enclose a reflux chamber 5b; the bottom of the diversion chamber 5a is communicated with the dust collecting box 51, and the top of the reflux chamber 5b is communicated with the negative pressure chamber 3a;

[0041] The front side of the filter cartridge frame 52 is evenly provided with mounting holes, which extend and penetrate the filter cartridge positioning plate 55. The filter cartridge 53 is installed in the mounting holes, and the rear side is plugged into the filter cartridge positioning plate 55. A spiral air guide 531 is provided at the front opening of the filter cartridge 53, and a conical air outlet pipe 532 is embedded in the rear opening of the filter cartridge 53. A guide outlet 53a is provided at the bottom of the filter cartridge 53, close to the conical air outlet pipe 532.

[0042] An exhaust fan 32 is provided at the lower rear side of the electrical cabinet 3 .

[0043] Based on the above structure, the air intake fan 31 and the exhaust fan 32 form an air cooling cycle to drive the high-speed air flow through the filter box 50, the filter cartridge holder 52, and the negative pressure chamber 3a to enter the installation space surrounded by the electrical cabinet 3 and the temperature control cabinet 2, so as to realize the air heat dissipation cycle in the space; the filter cartridge holder located on the air intake side cooperates with the filter cartridge to separate and collect the particulate impurities in the body, wherein the air intake fan 31 continuously works to form a low-pressure area in the negative pressure chamber 3a, so that the external gas is subjected to atmospheric pressure and passes through the filter cartridge 53 and the filter cartridge 53 along the reflux chamber 5b to enter the negative pressure chamber 3. In a, when the high-speed airflow passes through the filter cartridge 53, a swirling wind is formed under the influence of the spiral air guide 531. Under the action of centrifugal force, high-density particulate impurities will be blown outward, and low-density air enters the conical air outlet pipe 532 from the middle and flows out. The small end of the conical air outlet pipe 532 faces inward, which is used to guide the low-density air in the middle and block the outer circle of particulate impurities. The particulate impurities are finally deposited at the bottom of the filter cartridge and are blown out from the guide port 53a driven by the airflow, and finally enter the dust collecting box 51 from the bottom of the diversion cavity 5a.

[0044] The temperature control cabinet 2 has an opening on the front side, the electrical cabinet 3 is a cabinet body with an opening on the front side, and the rear side of the electrical cabinet 3 is buckled at the front opening of the temperature control cabinet 2; the panel 4 is buckled at the front opening of the electrical cabinet 3; and a plurality of heat conducting strips 33 extending vertically downward are provided on the back of the cabinet body of the electrical cabinet 3.

[0045] In order to achieve better heat dissipation effect, the temperature control cabinet in this application is designed as a C-shaped structure, and a C-shaped opening is formed on the front side so that the top, rear and bottom of the electrical cabinet 3 are all surrounded by the air circulation passage formed by the temperature control cabinet 2, thereby increasing the contact area between the electrical cabinet 3 and the heat dissipation circulation loop; the size and shape of the electrical cabinet 3 are consistent with the C-shaped opening to ensure that the internal circulation channel is relatively closed; the panel 4 is used to install various display panels, control panels and other structures, and at the same time serves as an auxiliary isolation protection structure of the rear electrical cabinet to improve the safety of the electrical cabinet.

[0046] The circulation component is used to construct a basic high-speed air cooling structure. In order to ensure a better refrigeration cycle effect, it should be ensured that the circulation loop can be in contact with the contactable heat-generating equipment as much as possible, and the length of the heat exchange loop and the area of ​​the interaction area should be extended. For this reason, the present application combines the structural form of the temperature control cabinet 2 to form a C-row circulation passage, and at the same time reasonably distributes the inlet and outlet loop structures to form a cross-air circulation with front air intake and rear air outlet, high-position air intake and low-position air outlet.

[0047] In particular, in order to further improve the heat dissipation and cooling effect, a water circulation heat conduction component is also provided in this embodiment, including: a water storage tank 6 provided at the rear side of the partition 30, and a return water tank 7 provided at the bottom of the temperature control cabinet 2;

[0048] The top of the temperature control cabinet 2 is a drainage panel 20 with a high front and a low back, and a return hole 2a is provided at the lowest point of the drainage panel 20; the top of the water storage tank 6 is a drainage panel 60 with a low front and a high back, and the rear side of the drainage panel 60 is located below the return hole 2a; a plurality of water inlet holes 6a are evenly provided on the drainage panel 60;

[0049] The heat conducting strip 33 is a hollow tube structure, wherein the upper end of the hollow tube is connected to the inner cavity of the water storage tank 6 through a pipeline, and the lower end is connected to the return water tank 7 through a pipeline;

[0050] A circulating water pump is provided in the return water tank 7 , and a water outlet pipe of the circulating water pump is connected to the water storage tank 6 .

[0051] The exhaust fan 32 is arranged above the return water tank 7, and a plurality of heat sinks 70 are arranged on the top of the return water tank 7. The heat sinks 70 are used to improve the heat dissipation effect of the cooling water in the return water tank 7 so that the cooling water can be dissipated through the bottom circulating airflow.

[0052] The drainage panels 20 and the guide panels 60 are evenly provided with drainage grooves 9a extending in the front-to-back direction, wherein the water inlet holes are located at the bottom of the drainage grooves. The drainage grooves can better collect and control the flow direction of water.

[0053] In particular, the front side of the drainage panel 20 is connected to the front edge of the top of the temperature control cabinet 2 in an openable and closable manner through a rotating shaft; the left, right and rear edges of the top of the temperature control cabinet 2 extend upward and are higher than the drainage panel 20 to form a water surrounding edge. The openable and closable structure is convenient for inspecting and maintaining the internal state, convenient for eliminating faults such as debris blocking the channel, and at the same time simplifies the structural design and reduces the processing and manufacturing costs.

[0054] In the present application, the drainage panel 20 and the guide panel 60 can realize the collection and utilization of natural precipitation on the one hand, and make the water flow form a water film to expand the heat exchange with the hot air on the other hand, so as to achieve the effect of cooling the air when the air temperature is high.

[0055] In order to discharge the excess water in time, an overflow hole is provided on the return water tank 7, and the overflow hole is connected to the outside through a pipeline, so that the excess water in the return water tank 7 can be led out to the outside.

[0056] In the present application, the rear shell surface of the electrical cabinet 3 is used to install various types of heat-generating electrical components during use, and also acts as a heat-conducting structure so that heat can be transferred to the rear air circulation and water-cooled heat-conducting strips. In order to improve the heat exchange effect, in this embodiment, an electric heat exchange plate is arranged between the charging unit and the rear inner wall of the electrical cabinet 3. The point heat exchange plate can consume electric energy to realize directional transfer control of heat, which can be used to further enhance the heat exchange effect and improve the heat dissipation efficiency.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
