Description

Technical Field

[0001] The present invention relates to the field of new energy charging, and in particular to a liquid-cooled charging seat for a new energy vehicle. Background Art

[0002] Due to the body resistance of the terminals, the crimping resistance of the cables, and the contact resistance of the male and female terminals, traditional new energy vehicle charging stations will generate heat when charging with high currents, causing the temperature of the charging device to rise, resulting in unstable charging.

[0003] Traditional new energy vehicle charging stations do not have heat dissipation devices and only rely on their own conductive heat dissipation, radiation heat dissipation and the current environmental heat dissipation. This is only passive heat dissipation, not active heat dissipation. Summary of the invention

[0004] In order to solve the above problems, the present technical solution provides a liquid-cooled charging station for new energy vehicles.

[0005] To achieve the above purpose, the technical solution is as follows:

[0006] A new energy vehicle liquid-cooled charging seat, comprising a connecting part for connecting to the charging seat, the connecting part is provided with a through cavity for a power cord to pass through, the connecting part is also provided with a first partition and a second partition to form two circulation chambers, wherein the bottom of the second partition is provided with a through hole connecting the two chambers, the connecting part is also provided with a circulation pipe respectively connected to the two chambers, a circulation pump is provided in one of the chambers, and when the circulation pump is working, the liquid in the circulation chamber is fully circulated through the circulation pipe.

[0007] In some embodiments, the second partition is detachably connected to the connecting portion.

[0008] In some embodiments, two sliding grooves for positioning and installing the second partition are provided in the connecting portion.

[0009] In some embodiments, it further includes a cover body threadedly connected to the connecting portion, and the circulation pipe passes through the cover body.

[0010] In some embodiments, a first sealing ring and a second sealing ring are respectively provided between the cover body and the connecting portion.

[0011] In some embodiments, the cover body is provided with an injection hole, a screw is provided in the injection hole, and the screw sleeve is provided with a third sealing ring.

[0012] In some embodiments, the screw is located below the first partition.

[0013] The beneficial effects of this application are:

[0014] This liquid-cooled charging stand has a compact structure and adopts a new alloy material one-piece molding process. The powerful water-liquid effect makes charging more stable, and the stable charging working temperature makes the service life of the liquid-cooled charging stand longer, which is significantly improved compared to traditional products.

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Please refer to Figure 1-4 As shown, a new energy vehicle liquid-cooled charging seat includes a connecting part 2 for connecting to a charging seat 1, the connecting part 2 is provided with a through cavity 3 for a power cord to pass through, the connecting part 2 is further provided with a first partition 4 and a second partition 5 to form two circulation chambers, wherein the second partition 5 is provided with a through hole 6 connecting the two chambers, the connecting part 2 is further provided with a circulation pipe 7 respectively connected to the two chambers, a circulation pump 8 is provided in one of the chambers, and when the circulation pump is working, the liquid in the circulation chamber is fully circulated through the circulation pipe.

[0022] There are the following advantages when using it:

[0023] The shell is made of a new alloy material in one piece, and a cavity is set inside to fill the coolant.

[0024] The new alloy material has good thermal conductivity and can efficiently transfer heat to the coolant, resulting in better heat dissipation effect;

[0025] The left and right chambers are separated by a partition, and holes are left at the bottom of the partition to achieve full circulation liquid cooling, and a vortex reflux pump is used to drive the coolant to circulate;

[0026] The vortex reflux pump is installed inside the left and right chambers, making the liquid-cooled charging station more compact and making better use of space.

[0027] The product adopts modular assembly technology, which makes installation and use more convenient;

[0028] Beneficial effects: On the premise of meeting the product functions, through efficient liquid cooling heat dissipation solutions, effective control of the temperature of the charging device, and convenient operation, the efficiency of charging of new energy vehicles is effectively improved, and unstable charging or even heat generation that causes a short service life of the entire charging device is avoided.

[0029] In this embodiment, the second partition plate 5 is detachably connected to the connecting portion 2, and the flow efficiency can be changed by replacing the partition plates with through holes of different apertures.

[0030] In this embodiment, two sliding grooves 9 for positioning and installing the second partition plate 5 are provided in the connecting portion 2, and the partition plates are quickly assembled through the sliding grooves.

[0031] In this embodiment, a cover body 10 threadedly connected to the connecting portion 2 is further included, and the circulation pipe 7 passes through the cover body 10 .

[0032] In this embodiment, a first sealing ring 11 and a second sealing ring 12 are respectively disposed between the cover body 10 and the connecting portion 2 .

[0033] In this embodiment, the cover body 10 is provided with a liquid injection hole, a screw 13 is provided in the injection hole, and the screw 13 is sleeved with a third sealing ring 14. After the screw is removed, the coolant is injected through the injection hole.

[0034] In this embodiment, the screw 13 is located under the first partition 4. When the coolant is injected, it can be poured into the two chambers at the same time until it reaches the top of the chamber and intersects at the through hole, thereby forming a circulation flow. At this time, the coolant can be completely contained in the periphery of the power cord, greatly improving the cooling effect.
