DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Example 1

[0041] In conjunction with the accompanying drawings, some implementation methods of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0042] Please refer to Figures 1 to 3As shown, an embodiment of the utility model provides a charging pile, which includes: a box body 101, a first air duct 102 is provided on a first side thereof, and a second air duct 103 is provided on a second side thereof; a waterproof air inlet 104 is provided on the outside of the first air duct 102, and a waterproof air outlet 105 is provided on the outside of the second air duct 103; at least one group of fans 201 is provided on the inside of the first air duct 102, and the fan 201 is connected to a wind cavity 202, and the wind cavity is connected to an air inlet 232 of a vortex tube 203 through a conduit 204; the vortex tube 203 also includes an air chamber 231, and a first end of the air chamber 231 is connected to a hot air outlet 234 through a pipe with a smaller diameter than the hot air outlet 234, and a V-shaped plug 235 with a smaller diameter than the hot air outlet 234 is provided inside the hot air outlet 234; the hot air outlet 234 extends out of the top of the box body 101, and a rain cover 236 is provided on the top thereof; a second end of the air chamber 231 is provided with a cold air outlet 233 with an inner diameter smaller than that of the air chamber;

[0043] The inner bracket has an electric energy conversion processing unit disposed therein, the electric energy conversion processing unit is provided with a heat sink, and the electric energy conversion processing unit is electrically connected to the charging gun via a cable extending out of the outlet 303; the cold air outlet 233 faces the heat sink; the box body 101 is provided with a sealed operation panel 301.

[0044] In this embodiment, two air ducts are arranged inside the box body 101 of the charging pile, namely, the first air duct 102 and the second air duct 103; wherein, the first air duct 102 introduces external air into the charging pile through the inner fan 201 and the wind cavity 202, as well as the structure of the duct 203 and the vortex tube 203, so that the air of the external environment can be provided for airflow exchange for cooling and heat dissipation; further, the fan 201 introduces airflow into the wind cavity 202 from the outside, and since the wind cavity 202 has a relatively large space, the gas will be compressed in the wind cavity 202, and the compressed gas will be sent from the air inlet 232 of the above-mentioned vortex tube 203 to the air chamber 231 of the above-mentioned vortex tube 203 through the duct 204, and the above-mentioned vortex tube 203 has a hot air outlet 234 located outside the box body and a V-shaped plug 235 structure therein, The hot air flow is discharged directly from the top of the box 101, and the above-mentioned rain cover 236 can effectively prevent rainwater from entering the box 101 from the above-mentioned hot air outlet 234; and the cold air outlet 233 of the above-mentioned vortex tube 203 fills cold air into the box. Since the power conversion processing unit is provided with a heat sink, and the above-mentioned cold air outlet 233 faces the heat sink, while dissipating heat, the equipment in the box is also cooled as a whole. After the gas enters the box through the cold air outlet 233, the air pressure in the box is increased, and then the gas is discharged through the air outlet 105 of the second air duct 103, so that the air pressure in the box 101 can be balanced, and the hot air is discharged outside the box 101; the above-mentioned waterproof air inlet 104 and waterproof air outlet 105 and the top rain cover 236 protect the equipment inside the charging pile from the influence of the external environment. At the same time, the box 101 is provided with a closed operation panel 301, which is convenient for charging operation and ensures that the equipment inside the charging pile is not affected by external conditions such as humidity, thereby improving the stability and service life of the equipment.

[0045] Example 2

[0046] The utility model embodiment provides a charging pile, referring to Figure 1 and Figure 5 As shown, the air inlet 104 and the air outlet 105 are both provided with a plurality of louver bars 141, and the louver bars 141 have an inclined surface inclined downwardly outwardly; Figure 8 and Fig. 9 As shown, the orthographic projections of two adjacent louvers 141 have overlapping parts. Through the louver 141 structure, the airflow entering the air inlet 104 is in an oblique direction from bottom to top, and the air outlet 105 discharges the airflow in an oblique direction from top to bottom, further preventing rainwater and water from entering the air inlet 104 and the air outlet 105 during spraying.

[0047] Further, such as Figure 8As shown, the louver bar 141 located at the bottom end is also provided with a water retaining groove 143 at its lower end; the water retaining groove 143 is located below the louver bar 141, and the water retaining groove 143 has an opening facing the outside of the box body 101; each louver bar 141 has an inclined surface facing the outside, and the lower end position of the upper inclined surface from top to bottom is not lower than the upper end position of the next louver bar 141, so that when water flows from the side of the box body to the above-mentioned louver bar 141, the water can fall into the above-mentioned water retaining groove 143 and flow out from the opening of the above-mentioned water retaining groove 143.

[0048] As a preferred implementation method, refer to Fig. 9 As shown, an insect-proof net 142 is also provided at the air inlet 104 and the air outlet 105. The insect-proof net 142 can prevent small flying insects or crawling insects from entering the charging pile from the vent 104 and causing adverse effects on the components inside the charging pile.

[0049] As a preferred implementation method, Figure 2 and Figure 3 As shown, the side of the air cavity 202 has adjustable folds, so that the size of the air cavity 202 can be adjusted.

[0050] Example 3

[0051] The utility model embodiment provides a charging pile, referring to Figure 3 and Figure 7 As shown, sound-absorbing cotton 304 is also included; the sound-absorbing cotton 304 is arranged on the outer inner wall of the first air duct 102 avoiding the air inlet 104, and is arranged on the outer inner wall of the second air duct 103 avoiding the air outlet 105.

[0052] As a preferred implementation method, Figure 1 and Figure 5 As shown, a charging gun protective cover 302 is also provided on the box body 101; the charging gun protective cover 302 has a plug-in port adapted to the charging gun port at its lower end for plugging in and placing the charging gun, and the charging gun is protected by the charging gun protective cover 302. When the charging gun is not used, it can be inserted into the plug-in port; a raised edge is provided on the edge of the charging gun protective cover 302 for hanging a cable connected to the charging gun. When the charging gun is not in use, the cable can be hung on the upper end of the charging gun protective cover 302, and the raised edge thereon can prevent the cable from slipping, thereby preventing the cable from being dragged on the ground and damaged.

[0053] As a preferred implementation method, refer to Figure 6 As shown, a mounting frame 131 is provided on the inner side of the second air duct 103, and a filter cotton 132 is provided on the mounting frame 131, which can effectively prevent impurities in the channel from clogging the pipeline, keep the channel unobstructed, and ensure normal airflow.

[0054] As a preferred embodiment, the inner bracket is further provided with an internal circulation fan (not shown in the figure), through which the air inside the box 101 can circulate, so that the temperature inside the box 101 is relatively balanced.

[0055] As a preferred implementation, the pipe 203 at least at one end of the hot air outlet 234 is provided with a heat insulation layer, such as heat insulation cotton, which can prevent heat from overflowing from the pipe wall, thereby further improving the cooling effect.

[0056] As a preferred implementation method, Figure 8 and Fig. 9 As shown, the outer side of the above-mentioned louver strips 141 is provided with an extension end extending horizontally downward, wherein, at the positions of the air inlet 104 and the air outlet 105, for every two adjacent louver strips 141, the extension end of the upper louver strip 141 is lower than the upper end of the lower louver strip 141. Through the above-mentioned extension ends, the projections of the lower and upper ends of adjacent louver strips 141 have overlapping parts, thereby preventing external water from splashing into the interior of the charging pile and improving its waterproof performance.

[0057] It should be noted that the vortex tube is a device that can use compressed gas to produce a refrigeration effect. The air is cooled to room temperature and then compressed. After passing through the nozzle, the air is accelerated and expanded. The accelerated airflow is input into the vortex finder to form a free vortex. The free vortex rotates in the pipe. The rotation speed at different angles and different vortex layers will cause friction. The heat generated will form a hot air flow, which will flow out through the separation plate. The vortex in the center layer loses energy due to friction, and the temperature will drop. It is led out from the other end through the separation plate in the pipe, thus achieving the refrigeration effect. Vortex tube refrigeration technology is a method of using the vortex tube to generate a vortex in high-speed airflow to separate cold and hot airflows, and obtain refrigeration using cold airflow. This refrigeration technology has the advantages of low cost, no chemicals, and almost no maintenance. The airflow temperature can also be controlled by a valve. Its maximum temperature range is usually between -46°C and 127°C (depending on the pressure and speed of the airflow). It is very suitable for industrial cooling and cooling parts and machines.
