Technical Field

[0001] The utility model relates to a charging pile, in particular to a DC integrated charging pile with a noise reduction function. Background Art

[0002] When the charging pile is installed near a residential area, the high-power DC charging pile will generate a lot of noise during nighttime charging in order to dissipate heat, which will affect the rest of nearby residents. It is necessary to control the noise at a distance of 1 meter from the charging pile. This will not affect the rest of nearby residents and improve the user experience. Utility Model Content

[0003] The purpose of the utility model is to provide a DC integrated charging pile with noise reduction function to solve the above technical problems.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a DC integrated charging pile with noise reduction function, comprising a charging pile, a front cabinet door, a control panel, a cable interface, a gun head interface, a side cabinet door, an air outlet, an air inlet shutter, and a noise reduction and heat dissipation channel, characterized in that: the front cabinet door is installed at the front end of the charging pile, the control panel is installed on the front cabinet door, the cable interface is installed at the front middle part of the side end of the charging pile, the gun head interface is opened on the upper side of the cable interface through the charging pile, the side cabinet doors are respectively installed at the rear of the left and right ends of the charging pile, the air outlet is opened on the left side cabinet door, the air inlet shutter is opened at the rear end of the charging pile, and the noise reduction and heat dissipation channel is arranged at the rear of the charging pile through the air inlet shutter.

[0005] On the basis of the above technical scheme, the noise reduction and heat dissipation channel includes a heat dissipation chamber, an exhaust fan, air outlet sound-absorbing cotton, partition sound-absorbing cotton, a charging module, a side door sound-absorbing cotton, an air inlet sound-absorbing cotton, and dust-proof cotton. The heat dissipation chamber is opened at the rear part of the charging pile, and the exhaust fan is installed at the air outlet through the heat dissipation chamber. The air outlet sound-absorbing cotton is distributed between the exhaust fan and the air outlet in a louver posture. The partition sound-absorbing cotton is vertically installed in the middle left part of the heat dissipation chamber, and the partition sound-absorbing cotton divides the heat dissipation chamber into an N-shaped air duct. The charging module is installed on the front side of the partition sound-absorbing cotton through the charging pile, and the side door sound-absorbing cotton is installed on the inner side of the side cabinet door through the heat dissipation chamber. The air inlet sound-absorbing cotton is blocked on the left side of the air inlet shutter through the partition sound-absorbing cotton, and the dust-proof cotton is distributed on the air inlet shutter through the heat dissipation chamber.

[0006] Based on the above technical solution, the external air is blown to the right along the air duct through the air inlet louver, passes through the right end of the separated sound-absorbing cotton, and then blows to the exhaust fan on the left to take away the heat from the charging module.

[0007] Compared with the prior art, the utility model has the following advantages: the utility model can reduce the noise generated by the side air intake by taking in air through the back. In addition, a layer of sound-absorbing cotton is designed at the air inlet to absorb part of the noise coming out of the air inlet. At the same time, the air duct is designed to be a curved air duct. When the width of the cabinet is the same, the length of the air duct can be effectively extended, and part of the noise can be eliminated by the mutual cancellation of sound waves inside the cabinet. There is no hole in the door panel on the right side of the cabinet, and sound-absorbing cotton is installed on the entire door panel. When the air flows to the right door panel, the direction of the airflow will change, and part of the noise will be absorbed by the sound-absorbing cotton to prevent the noise on the right side of the cabinet from being too loud.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 4 As shown, a DC integrated charging pile with noise reduction function includes a charging pile 1, a front cabinet door 2, a control panel 3, a cable interface 4, a gun head interface 5, a side cabinet door 6, an air outlet 7, an air inlet shutter 8, and a noise reduction heat dissipation channel 9, characterized in that: the front cabinet door 2 is installed at the front end of the charging pile 1, the control panel 3 is installed on the front cabinet door 2, the cable interface 4 is installed at the front middle part of the side end of the charging pile 1, the gun head interface 5 is opened on the upper side of the cable interface 4 through the charging pile 1, the side cabinet doors 6 are respectively installed at the rear of the left and right ends of the charging pile 1, the air outlet 7 is opened on the left side cabinet door 6, the air inlet shutter 8 is opened at the rear end of the charging pile 1, and the noise reduction heat dissipation channel 9 is arranged at the rear of the charging pile 1 through the air inlet shutter 8.

[0015] The noise reduction and heat dissipation channel 9 includes a heat dissipation chamber 10, an exhaust fan 11, an outlet sound-absorbing cotton 12, a partition sound-absorbing cotton 13, a charging module 14, a side door sound-absorbing cotton 15, an air inlet sound-absorbing cotton 16, and a dust-proof cotton 17. The heat dissipation chamber 10 is opened at the rear of the charging pile 1, and the exhaust fan 11 is installed at the air outlet 7 through the heat dissipation chamber 10. The air outlet sound-absorbing cotton 12 is distributed between the exhaust fan 11 and the air outlet 7 in a louver posture. The partition sound-absorbing cotton 13 is vertically installed in the middle left part of the heat dissipation chamber 10, and the partition sound-absorbing cotton 13 divides the heat dissipation chamber 10 into an N-shaped air duct. The charging module 14 is installed on the front side of the partition sound-absorbing cotton 13 through the charging pile 1, and the side door sound-absorbing cotton 15 is installed on the inner side of the side cabinet door 6 through the heat dissipation chamber 10. The air inlet sound-absorbing cotton 16 is blocked on the left side of the air inlet louver 8 through the partition sound-absorbing cotton 13, and the dust-proof cotton 17 is distributed on the air inlet louver 8 through the heat dissipation chamber 10.
