Description

Technical Field

[0001] The present invention relates to the technical field of charging pile design, and in particular to a high-power liquid-cooled charging pile. Background Art

[0002] A charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electric energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging piles are divided into public charging piles and private charging piles, and are divided into AC charging piles and DC charging piles in terms of charging methods.

[0003] When charging, the current will generate heat when passing through the resistor. According to the law of conservation of energy, this part of the electric energy will be converted into heat energy and dissipated into the surrounding environment. In particular, DC fast charging piles usually have a large power, such as the common 60kW, 120kW or even higher power charging piles, which generate more considerable heat when working.

[0004] In addition, the electronic components inside the charging pile, such as the power module and inductor module, will also generate a lot of heat under high current and high voltage working conditions. For example, for a charging pile with a power of 60kW, the heat dissipation of the module alone can reach about 3000W, which greatly increases the heat dissipation demand of the entire charging pile.

[0005] In addition, in order to facilitate users to charge electric vehicles, the charging cables used by the charging heads on traditional charging piles are designed to be longer. When the charging piles are not in use, the charging cables are scattered on one side of the charging piles, which may be kicked and trip pedestrians or cause the charging heads to fall to the ground and break, resulting in certain inconveniences when using the charging piles.

[0044] A positioning device 2 is provided on one side of the cabinet 1;

[0045] The positioning device 2 includes a slot rod 21, one end of which is fixedly connected to one side of the cabinet 1, and the other end is connected to a T-shaped rod 22; the outer surface of the T-shaped rod 22 slides on the inner wall of the slot rod 21, and the distance between the T-shaped rod 22 and the cabinet 1 is controlled and fixed by a second screw rod 28;

[0046] When charging is finished, the cable 7 is wound around the slot rod 21 to store the cable 7 .

[0047] The lower end of the inner wall of the T-shaped rod 22 is slidably connected to a sliding rod 24, and one side of the sliding rod 24 is fixedly connected to a rectangular rod 25, which is located below the groove rod 21;

[0048] When charging is finished, the cable 7 is wound around the grooved rod 21 and the rectangular rod 25 to store the cable 7 .

[0049] The lower end of the T-shaped rod 22 is provided with a slot, and the position of the sliding rod 24 is controlled by the sliding distance of the first screw rod 26 and the threaded ring 27 in the slot, thereby adjusting the distance between the rectangular rod 25 and the groove rod 21, so as to adjust the number of winding turns of the cable 7 when it is stored.

[0050] A collar 23 is fixedly connected to the upper end of the T-shaped rod 22 for accommodating the charging head 8 .

[0051] A threaded ring 27 is threadedly connected to the outer surface of the first screw rod 26 , and a stopper 29 is fixedly connected to the end thereof to prevent the threaded ring 27 from being separated from the first screw rod 26 .

[0052] A gasket 210 is fixedly connected to one side of the threaded ring 27 , and the gasket 210 is made of rubber.

[0053] The heat sink 6 is provided with a filter screen inside and a plurality of through holes are opened on the outer surface.

[0054] After charging is completed, the second screw rod 28 is rotated to control the T-shaped rod 22 to slide on the inner wall of the groove rod 21, and the distance between the T-shaped rod 22 and the cabinet 1 is adjusted and fixed; the sliding rod 24 is pushed to slide on the inner wall of the T-shaped rod 22, and the distance between the rectangular rod 25 and the groove rod 21 is adjusted.

The brush piece 33 on one side of the push rod 32 can sweep away the dust accumulated on the through holes on the outer surface of the heat sink 6 and the filter surface, and the dust can be blown out by the wind force blown out by the heat exchanger 5, so as to avoid dust accumulation on the surface of the heat sink 6 and affect the heat dissipation effect of the heat exchanger 5 as much as possible.

[0064] A slot block 34 is fixedly connected to the outer side of the push rod 32 , and two grooves are formed on the outer surface of the slot block 34 .

[0065] By pinching the two grooves on the outer surface of the groove block 34 , it is more convenient to pinch the groove block 34 to control the push rod 32 to move back and forth, thereby improving the convenience when using the cleaning device 3 .

[0066] A positioning block 35 is fixedly connected to the bottom end of the push rod 32 , and one side of the positioning block 35 slides on one side of the cabinet 1 .

[0067] When the push rod 32 moves back and forth on one side of the cabinet 1, one side of the positioning block 35 will slide on the outer surface of the cabinet 1. The positioning block 35 can further limit the angle between the push rod 32 and the cabinet 1 to avoid shaking of the push rod 32 when moving.

[0068] This high-power liquid-cooled charging pile not only solves the heat dissipation problem of the charging pile, but also solves the problem of cable storage;

[0069] By setting a positioning device, when the charging pile is not in use, the cable can be wrapped around the outer surface of the groove rod and the rectangular rod and the charging head can be inserted into the ring to facilitate the storage and fixation of the cable on one side of the cabinet, thereby avoiding the cable from being scattered around the cabinet and being accidentally damaged as much as possible. The number of cable wraps can be changed by adjusting the position of the sliding rod, thereby improving the convenience and practicality of using the charging pile.

[0070] The embodiment described above is only one specific implementation of the present invention.
