[0002] The liquid-cooled supercharging terminal is an electrical integrated device that enables fast charging of electric vehicles. The input is three-phase power electricity, which is converted from AC to DC by the power module, and then charged by DC devices. The power module is the core component for realizing current conversion and is also the most important heat source component. To achieve stable operation of various components of the charging pile, heat needs to be dissipated in time. Chinese patent CN202223594563.7 discloses a high-power liquid-cooled DC charger, but because the liquid cooler in this solution is located at the bottom of the cabinet, the power line needs to enter from the narrow bottom of the cabinet and connect to the DC input unit located on the top of the liquid cooler, which makes on-site wiring difficult and increases construction costs.

DETAILED DESCRIPTION

[0016] The utility model is described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 and 2As shown, this embodiment discloses a liquid-cooled supercharging terminal, wherein a control unit 1, a liquid cooler 2 and a DC input-output unit 3 are arranged inside the cabinet from top to bottom, and the cabinet comprises a front door 4, a right door 5, a rear door and a left door 6 which are connected in sequence, and the front door 4 is provided with an air inlet 7 corresponding to the DC input-output unit 3, and a fan is arranged at the air inlet 7, and the right door 5 or the left door 6 is provided with an air outlet 8, and the inner wall of the cabinet is provided with an air guide plate 9 for allowing cold air to flow from the air inlet 7 through the liquid cooler 2 and out of the air outlet 8. The DC input-output unit 3 is installed at the position directly below the cabinet, so that the equipment incoming line is closer to the wiring position, which saves cables and makes wiring more convenient; the DC output wiring is close to the fixed position of the gun line, which makes the gun line wiring more convenient. Through reasonable layout, the overall size of the cabinet is smaller, the height is lower, and the processing cost is reduced. Sufficient space is left for the DC input unit and the DC output unit, which is more convenient for equipment installation and user wiring. Cold air flows through the DC input-output unit 3 and the liquid cooler 2 in sequence, which has a good heat dissipation effect.

[0018] In this embodiment, if Figure 1 As shown, the air outlet 8 is located on the right door 5 or the left door 6, and the air outlet 8 is arranged corresponding to the DC input and output unit 3. The air guide plate 9 prevents the wind blown out of the fan from blowing out directly along the fan, but the wind is discharged under the guidance of the air guide plate 9, which is equivalent to extending the air duct 13, lowering the position of the noise source and further away from the human ear, thereby achieving the purpose of noise reduction.

[0019] In this embodiment, if Figure 1 As shown, the air outlet 8 is arranged on the right door 5, one end of the air guide plate 9 is connected to the right door 5, and a partition 10 for installing the liquid cooler 2 is arranged between the other end of the air guide plate 9 and the left door 6, and the partition 10 divides the inner part of the cabinet into an upper chamber 11 and a lower chamber 12. There are two air guide plates 9, and the two air guide plates 9 are arranged to form an air duct 13, and the upper chamber 11, the lower chamber 12, and the air duct 13 are connected in sequence. The air guide plate 9 is connected to the position of the right door 5 corresponding to the DC input and output unit 3, and the air outlet 8 can also be arranged on the left door 6, and the air guide plate 9 is connected to the left door 6. There is a gap between the air guide plate 9 and the front door 4, so that the upper chamber 11 and the lower chamber 12 are connected. The liquid cooler 2 is located in the upper chamber 11, and the DC input and output unit 3 is located in the lower chamber 12. There are two air guide plates 9, and the two air guide plates 9 are correspondingly arranged to form an air duct 13. The flow path of the cold air is the air inlet 7-lower chamber 12-upper chamber 11-air duct 13-air outlet 8, thereby ensuring the heat dissipation of the DC input and output unit 3 and the liquid cooler 2.

[0020] In this embodiment, if Figure 1As shown, the air inlet 7 is filled with dustproof cotton. The dustproof cotton plays a filtering role. The front door 4 is rotatably connected to the left door 6 through a hinge. The front door 4 and the inner wall of the air guide plate 9 are provided with soundproof cotton 14. The soundproof cotton 14 plays an effect of isolating noise.

[0021] In this embodiment, if Figure 1 As shown, the front door 4 is provided with a human-machine interaction unit 15, and the human-machine interaction unit 15 is electrically connected to the control unit 1. The user controls through the human-machine interaction unit 15. The control unit 1 is an integrated motherboard. The integrated motherboard is highly integrated, which reduces the design failure points, makes wiring more convenient, improves the reliability and maintainability of the control unit 1, and reduces the system cost.

[0022] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
