Description

Technical Field

[0001] This utility model relates to the field of charging bases for new energy vehicles, and in particular to a split-type liquid-cooled charging base for new energy vehicles. Background Technology

[0002] With the government's policy support for new energy, new energy vehicles are developing rapidly. These vehicles require efficient, fast, and safe charging. To shorten charging time, existing fast charging technologies use high-power charging (such as fast DC charging). However, the connection between the charging gun and the charging socket's power terminals generates a significant amount of heat. This has several drawbacks: First, the resistance of the charging socket's DC terminals is directly proportional to temperature rise; continuous heating affects terminal performance and reduces charging speed. Second, the continuous temperature increase of electronic components may cause overheating and component failure, potentially even leading to combustion and posing a safety risk, impacting charging safety. Third, the continuous high temperature of electronic components within the charging socket causes frequent equipment shutdowns, hindering stable operation, resulting in low charging efficiency, and potentially affecting component lifespan in the long run.

[0005] A vertical plate is threadedly connected to the middle of the inner wall of the housing, and the power terminal bushing at the front end of the housing is connected to the shaft hole of the positioning platform of the vertical plate.

[0006] The cooling module includes a liquid cooling box made of thermally conductive material and thermally conductive pads.

The set screw passes through the end shaft hole of the adapter copper busbar connecting the power terminal and presses the liquid cooling box forward to fix it to the back of the vertical plate.

[0007] The two inlet and outlet ports of the liquid cooling box are connected to the coolant circuit. The heat generated by the copper busbar is conducted to the coolant in the liquid cooling box through the thermal pads and the box cover, thereby achieving heat dissipation.

[0008] In some embodiments, the liquid cooling box includes an open heat dissipation shell, with a number of fins integrally and vertically connected to the rear side of the bottom wall of the heat dissipation shell. The fins are flush with the circumferential ring wall and are all in contact with the box cover, dividing the inner cavity of the heat dissipation shell into a number of cooling channels.

[0009] In some implementations, the two inlet and outlet ports are located on the circumferential ring wall, and the fins are tilted at a certain angle near the inlet and outlet ports.

[0010] In some embodiments, a positioning hole is provided at the end corner of the heat sink, and a positioning post is provided at the corresponding position on the front side of the cover, with the positioning post inserted into the positioning hole.

The axial positioning hole 100 of the liquid cooling box 1 surrounds and connects to the positioning platform 020. The liquid cooling box 1 is positioned in front of the adapter copper busbar 3 connecting the power cable 06.

The thermally conductive silicone pad 6 facilitates the connection between the two adapter copper busbars 3 and the cover plate 2, and at the same time, it has high thermal conductivity and can achieve good cooling function.

[0032] The set screw 05 passes through the end shaft hole of the power terminal 04 connected to the adapter copper busbar 3, and presses the liquid cooling box 1 forward to fix it against the back of the vertical plate 02;

[0033] The two inlet and outlet ports 12 of the liquid cooling box 1 are connected to the coolant circuit. The heat generated by the copper busbar 3 is conducted to the coolant in the liquid cooling box 1 through the thermal pad 2 and the box cover 11, thereby achieving heat dissipation.

[0034] This new energy vehicle split-type liquid-cooled charging base has an independent cooling module 03, which dissipates heat from the internal copper busbar 3 and its connections.

Second, the cooling module 3 is equipped with a liquid cooling box 1 made of thermally conductive material. The liquid cooling box is fixed inside the vertical plate 02. This structure is easy to disassemble and assemble, allowing for quick replacement of parts and convenient maintenance. Third, the liquid cooling box is positioned by the positioning platform 020 and axially fixed by the set screws 05.

[0041] The heat sink 10 is divided into left and right end cavities by an axial positioning hole 100 and connected by a central channel. The left and right end cavities of the heat sink 10 are respectively provided with a number of fins 103.

[0042] Two liquid inlet and outlet ports 12 are symmetrically distributed on the left and right end cavities, and the lower end of the fins 103 is inclined towards the liquid inlet and outlet ports 12. The beneficial effect is that this arrangement allows the coolant in the cooling channel 104 to flow fully around the power terminals, achieving rapid and efficient heat dissipation.

[0043] Furthermore, the inlet and outlet ports 12 are vertical pipes, and each inlet and outlet port 12 is threaded with a water nozzle 4. The water nozzle 4 is connected to the coolant circuit through a water pipe 5.
