DETAILED DESCRIPTION

[0026] The present invention provides Figure 1 A DC charging device using a vertical air duct is shown, comprising a device body 1, and further comprising: The heat dissipation mechanism 2 arranged on the inner side of the device body 1 is used to dissipate heat from the operation of the device body 1. The heat dissipation mechanism 2 constitutes a vertical air duct, so that air can flow fully in the device body 1, which can improve the heat dissipation efficiency of the device body 1. At the same time, the design of the vertical air duct can save the floor space of the device body 1.

[0027] In order to facilitate the heat dissipation of the internal working modules of the device body 1, Figure 1-6 and Figure 8 As shown, the heat dissipation mechanism 2 includes a first air inlet 201 and a second air inlet 203. The first air inlet 201 is opened at the bottom of one side of the device body 1, and a first air outlet 202 is opened at the top of one side of the device body 1. The second air inlet 203 is opened at the bottom of the other side of the device body 1, and a second air outlet 204 is opened at the top of the other side of the device body 1. A lower partition 206 and an upper partition 207 are fixedly installed at the bottom and top of one side of the device body 1 respectively, a guide plate 210 is fixedly installed at the top of the other side of the device body 1, a partition plate 208 is fixedly installed at the top of the inner side of the device body 1, and a cooling fan 205 is installed on the top of the partition plate 208; The cooling fan 205 operates so that air can flow into the interior of the device body 1 through the first air inlet 201 and the second air inlet 203. After the guiding effect of the lower partition 206, the upper partition 207, the guide plate 210 and the partition plate 208, the cold air can fully flow inside the device body 1, and the heat generated by the operation of the modules inside the device body 1 can be sent out. The hot air can be discharged from the interior of the device body 1 through the first air outlet 202 and the second air outlet 204. The air duct adopts a vertical design, so that the air can form an orderly vertical flow inside the charging pile, which improves the efficiency of the charging process. The heat dissipation efficiency is improved and precise heat dissipation is achieved. At the same time, the first air inlet 201 and the second air inlet 203 are both installed with air filter cotton. The air filter cotton adopts a detachable design, which is convenient for regular cleaning and replacement. The first air outlet 202 and the second air outlet 204 are both installed with a protective net. The combination of the air filter cotton at the air inlet and the protective net at the air outlet effectively prevents dust and other impurities from entering the interior of the charging pile, protects electronic components, and improves the reliability and stability of the charging pile. At the same time, the design of the vertical air duct can better save the floor space of the equipment body 1 and improve space utilization.

[0028] In order to save equipment space and ensure its stable operation, such as Figure 1-7 As shown, the device body 1 includes a cabinet 101, a fixed base 102 is fixedly installed at the bottom of the cabinet 101 by bolts, a front door 103 is fixedly installed on one side of the cabinet 101 by bolts, a canopy 104 is fixedly installed on the top of the cabinet 101 by bolts, a right door 107 is fixedly installed on the outer wall of one side of the cabinet 101, and a left door 108 is fixedly installed on the outer wall of the other side of the cabinet 101. A DC unit mounting plate 105 is fixedly installed on the top of the side of the cabinet 101 near the front door 103, an AC unit mounting plate 106 is fixedly installed on the bottom of the side of the cabinet 101 near the front door 103, a module mounting plate 109 is fixedly installed on the side of the cabinet 101 away from the DC unit mounting plate 105, and a charging module 110 is fixedly installed on the inner side of the module mounting plate 109. The module 110 is arranged below the partition plate 208. A heat insulation device is applied or pasted between the air duct plate and the heating part of the charging module 110 to improve the heat transfer efficiency. The cabinet 101 is made of high-quality steel plates and is processed through cutting, bending, welding and other processes. The surface of the cabinet 101 is sprayed with plastic to improve its corrosion resistance and aesthetics. The AC / DC charging module 110 is installed on the AC / DC module mounting plate 109 inside the cabinet 101, and the power and signal lines are connected. The position of the AC / DC charging module 110 and the vertical air duct assembly must correspond accurately to ensure that heat can be smoothly transferred to the air duct. Due to the unique vertical air duct design, the noise of the AC / DC charging module 110 cannot be directly transmitted to the outside of the cabinet 101, reducing noise pollution.

[0029] In order to make the heat dissipation mechanism 2 able to stably dissipate heat from the charging module 110, Figure 2-7 As shown, the first air inlet 201 and the first air outlet 202 are respectively opened at the bottom and top inner wall of the right door 107, the second air inlet 203 and the second air outlet 204 are respectively opened at the bottom and top inner wall of the left door 108, the bottom of the side of the cabinet body 101 near the left door 108 is fixedly connected to the lower partition 206, the top of the side of the cabinet body 101 near the left door 108 is fixedly connected to the upper partition 207, the top of the side of the cabinet body 101 near the right door 107 is fixedly connected to the guide plate 210, the top of the inside of the cabinet body 101 is fixedly connected to the partition plate 208, and the top of one end of the partition plate 208 near the guide plate 210 is fixedly installed with a support partition 206. 9. The lower partition 206 is arranged above the second air inlet 203, the upper partition 207 is arranged below the second air outlet 204, and the guide plate 210 is arranged below the first air outlet 202. The various mounting plates, module mounting plates 109, and multiple air duct partitions inside the cabinet 101 are fixed at various positions inside the cabinet according to design requirements to form multiple independent vertical air ducts. The air duct plate and the cabinet 101 are connected by bolts to ensure a firm connection. A heat insulation device is applied or pasted between the air duct plate and the heating part of the charging module 110 to improve the heat transfer efficiency, so that the heat dissipation mechanism 2 can fully dissipate the heat of the charging module 110, which can improve the heat dissipation effect of the equipment.

[0030] The specific implementation method is as follows: when installing and using the device body 1, high-quality steel plates are used according to needs, and are processed into a cabinet 101 through cutting, bending, welding and other processes, and the surface is sprayed with plastic. At the same time, the DC unit mounting plate 105, the AC unit mounting plate 106 and the module mounting plate 109 are installed inside the cabinet 101 with bolts, and the charging module 110 is installed on the inside of the module mounting plate 109. Then, the lower partition 206 is installed to the bottom of one end of the cabinet 101 near the left door 108, and the upper partition 207 is installed to the top of one end of the cabinet 101 near the left door 108, and then the guide plate 210 is installed. It is installed inside the cabinet 101 at one end near the right door 107, and a partition plate 208 is installed on the top of the module installation plate 109. Then, a support partition 209 is installed on the top of the partition plate 208 near the guide plate 210. Then, a first air inlet 201 and a first air outlet 202 are opened on the inner wall of the left door 107, and a second air inlet 203 and a second air outlet 204 are opened on the inner wall of the right door 108. At the same time, detachable air filter cotton is installed at the two air inlets. Then, a cooling fan 205 is installed on the top of the partition plate 208 so that its air outlet side corresponds to the position of the first air outlet 202 and the second air outlet 204. When the charging device is assembled, the power is turned on, the motor is started, and the cooling fan 205 is operated, so that the outside air can enter the cabinet 101 through the first air inlet 201 and the second air inlet 203, and pass through the guiding effect of the lower partition 206, the guide plate 210 and the supporting partition 209, so that the air can pass through the inside of the charging module 110, and the heat generated by the operation of the charging module 110 can be sent out through the flow of air, and then pass through the guiding effect of the upper partition 207 and the partition plate 208, and then under the action of the cooling fan 205, the hot air is discharged. The air can be discharged from the inside of the cabinet 101 through the first air outlet 202 and the second air outlet 204. The design of the vertical air duct allows the air to form an orderly vertical flow inside the charging pile, which can fully dissipate the heat of the charging module 110, improve the heat dissipation efficiency, and achieve precise heat dissipation. Compared with the liquid-cooled heat dissipation system, the air-cooled heat dissipation structure of the present invention is simpler and has lower cost. It is also easy to install and maintain and has higher market competitiveness. This embodiment specifically solves the problems of low heat dissipation efficiency, large occupied area and noise pollution of charging equipment in the prior art.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
