[0002] In recent years, with the intensification of global climate change, the harm and impact of the greenhouse effect. The global oil resources are becoming increasingly depleted. As a new energy force, electric cars are impacting the domestic fuel vehicle market economy with a rapid growth trend. In order to promote environmentally friendly and low-carbon travel, reduce dependence on oil resources, improve energy utilization, and protect the environment. The government has introduced relevant policies to subsidize car purchases and replacements, and more and more customer groups have flocked to electric cars. This has caused a sharp increase in the demand and dependence on charging stations and charging piles. However, the existing charging pile rectifier cabinet installs the power module with high heat generation and the electrical components with relatively low heat generation in the cabinet without separation, resulting in the power module with high heat generation transferring heat to the vicinity of the electrical components, thereby affecting the working efficiency of the electrical components. For this reason, we propose a DC charging pile rectifier cabinet. Utility Model Content

[0026] See also Figure 1-6 , the utility model provides a technical solution:

[0027] A DC charging pile rectifier cabinet, such as Figure 1-3 As shown, it includes a cabinet 1 and a partition 2 installed in the cabinet 1. The partition 2 is arranged horizontally to form two independent chambers inside the cabinet 1. The power module is installed on the partition 2. The inner bottom wall of the cabinet 1 is connected to a plurality of support frames 3 with the tops against the lower end of the partition 2. The electrical components are installed on the support frames 3. The support frames 3 not only improve the supporting strength of the partition 2, but are also used for the installation of electrical components. Shutters 4 are installed on both sides of the cabinet 1 for ventilation and heat dissipation.

[0028] In some examples, the shutter 4 is installed on the side wall of the cabinet 1 above the partition 2 to isolate the electrical components from the outside and prevent them from being corroded by rain.

[0029] It should be noted that a through hole is provided on the partition 2 , and a cooling fan 21 is installed in the through hole. When the cooling fan 21 is started, the heat generated by the electrical components is discharged through the shutter 4 .

[0030] The partition 2 separates the battery module and the electrical components to prevent the heat from being transferred to each other and affecting the working efficiency.

[0031] In some examples, a fan mounting frame 5 is installed on one side of one of the shutters 4 close to the inner cavity of the cabinet 1, and a plurality of cooling fans 2 51 are installed on the fan mounting frame 5. When the cooling fans 2 51 are started, the heat inside the cabinet 1 is taken out. A dust screen is attached to the other shutter 4. When opened, the two shutters 4 form convection, effectively discharging the heat in the chamber where the battery module is installed. A cooling fan 1 21 is installed on the partition 2. When opened, the heat in the chamber where the electrical components are installed is effectively discharged through the shutter 4.

[0032] See also Figure 4 The shutter 4 includes a shutter frame 41 and a plurality of shutter blades 42. The plurality of shutter blades 42 are sequentially arranged on the inner side of the shutter frame 41 from top to bottom. Figure 6 As shown, the louver 42 is in a bent structure, and the top of the lower louver 42 of any two adjacent louvers 42 exceeds the bottom of the upper louver 42, which does not affect the heat flow and prevents rainwater from entering the cabinet 1.

[0033] For some examples, see Figure 5 The louver 42 includes a vertical plate 1 421 and a vertical plate 2 425 which are arranged in parallel and not on the same plane, and the bottom of the vertical plate 2 425 is higher than the top of the vertical plate 1 421, and an oblique plate 2 424 is connected between the top of the vertical plate 1 421 and the bottom of the vertical plate 2 425, and the two sides of the vertical plate 1 421 are connected to the card block 423. The louver frame 41 is provided with a card slot, which allows the louver 42 to be fixed to the louver frame 41 when the card block 423 is embedded therein, and the louver 42 is easy to disassemble and install.

[0034] In some examples, the lower end of vertical plate 1 421 is connected to an inclined plate 1 422 inclined toward one side of vertical plate 2 425 to reduce the height of raindrops and the risk of rainwater splashing into the cabinet 1. The upper end of vertical plate 2 425 is connected to a baffle 426 extending toward one side of vertical plate 1 421 and arranged horizontally. Baffle 426 blocks splashing rainwater from entering the cabinet 1.

[0035] It should be noted that the thickness of the louver frame 41 is not less than the horizontal distance between the vertical plate 1 421 and the vertical plate 2 425 , and the periphery of the louver frame 41 is sealed to prevent rainwater from intruding.

[0036] The above embodiments are merely illustrative of the principles and effects of this patent application, and are not intended to limit this patent application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of this patent application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in this patent application should still be covered by the claims of this patent application.
