Referring to fig. 1 to 3, the present utility model provides a cooling system applied to a charging gun 200, wherein the charging gun 200 is provided with a housing 220 and a charging electrode 210 disposed in the housing 220. The cooling system includes an insulating heat conductive member 110 and a heat sink 120, the insulating heat conductive member 110 being used to connect with the charging electrode 210. The heat sink 120 is connected to the insulating heat conductive member 110, and the heat sink 120 extends to the outside of the charging gun 200, and the heat of the charging electrode 210 is transferred to the outside of the case 220 through the insulating heat conductive member 110 and the heat sink 120. Specifically, the heat generated at the charging electrode 210 is transferred to the insulating and heat conducting member 110, and the insulating and heat conducting member 110 transfers the heat to the heat sink 120, and the heat sink 120 transfers the heat to the outside air. Because the cooling fin 120 extends to the outside of the shell 220, the heat of the cooling fin 120 can be quickly exchanged with the external air, so that the heat at the charging electrode 210 is timely conducted to the atmosphere, the heat transfer efficiency is high, the cooling effect on the charging electrode 210 is good, the temperature at the charging electrode 210 is prevented from being too high, and the charging safety is improved.

Optionally, the heat sink 120 is provided as at least a portion of the housing 220. Thus, the structure of the case 220 can be simplified, and the heat dissipation area of the heat sink 120 can be increased. In addition, the heat sink 120 replaces a part of the housing 220, so that the weight and the volume of the whole charging gun 200 can be reduced, and the charging gun 200 can be conveniently taken and placed. In some embodiments, the heat sink 120 may be used instead of the whole housing 220 to further increase the heat dissipation area and improve the heat dissipation efficiency. The heat sink 120 may be made of a metal material such as an aluminum integrated part or a copper heat sink. The heat sink 120 and the housing 220 may also be integrally manufactured.

In the present embodiment, the heat dissipation fins 120 are arranged in an arc shape or a wave shape, so as to increase the heat dissipation area and the heat dissipation efficiency on the premise of saving the volume. It is understood that the number of the heat sinks 120 may be one or more, and the distribution manner thereof may be flexibly set. For example, the heat sink 120 is disposed in a ring shape around the charging electrode 210, i.e., is connected around the insulating and heat conducting member 110, or is connected to opposite sides of the insulating and heat conducting member 110, or is connected to one side of the insulating and heat conducting member 110, which is not particularly limited herein.

The insulating and heat conducting member 110 may employ a ceramic heat conducting block. The ceramic heat conducting block is an insulating member and is fixedly connected with the charging electrode 210. It is easily understood that the charging electrode 210 includes a positive electrode 211 and a negative electrode 213. The ceramic heat conducting blocks are connected with the positive electrode 211 and the negative electrode 213 respectively. In this embodiment, the ceramic heat conducting block is a rectangular plate, and mounting holes for the charging electrode 210 to pass through are respectively formed at two ends of the ceramic heat conducting block. The ceramic heat conducting block can be fixedly connected with the charging electrode 210 by adopting modes of bonding, clamping or bolting, and the like, and the ceramic heat conducting block is in close contact with the charging electrode 210, so that heat generated by the charging electrode 210 can be quickly conducted to the radiating fin 120.

It can be appreciated that the charging electrode 210 is inserted into the insulating heat conducting member 110, and the heat sink 120 is disposed around the outer side of the insulating heat conducting member 110, so as to increase the contact area between the insulating heat conducting member 110 and the charging electrode 210, and increase the heat exchange area between the heat sink 120 and the insulating heat conducting member 110, thereby improving the heat dissipation efficiency.

Of course, in other embodiments, other heat conductive objects such as heat conductive glue may be used for the insulating and heat conductive member 110, which is not particularly limited herein.

The cooling system further includes a heat transfer member 130, the heat transfer member 130 being connected between the insulating heat conductive member 110 and the heat sink 120. In this way, the heat generated at the charging electrode 210 is transferred to the insulating and heat conducting member 110, the insulating and heat conducting member 110 transfers the heat to the heat transfer member 130, the heat transfer member 130 transfers the heat to the heat sink 120, and the heat sink 120 transfers the heat to the outside air.

Optionally, the heat transfer member 130 includes at least one of a semiconductor cooling fin 140, a soaking plate 150, and a heat pipe. In other words, the heat transfer member 130 may employ the semiconductor cooling fin 140 alone, the soaking plate 150 alone, or both the semiconductor cooling fin 140 and the soaking plate 150. The heat transfer efficiency can be further increased by the heat transfer member 130, and the heat dissipation effect can be improved.

The insulating and heat conducting member 110 transfers heat to the semiconductor cooling fin 140, and the semiconductor cooling fin 140 transfers heat to the heat sink 120. By providing the semiconductor cooling fin 140, the semiconductor cooling fin 140 can rapidly reduce the temperature of the insulating and heat conducting member 110, thereby absorbing a large amount of heat of the charging electrode 210 and achieving the effect of rapid cooling.

Of course, in some embodiments, the heat transfer member 130 may also be connected between the insulating heat conductive member 110 and the charging electrode 210. The heat transfer member 130 includes at least one of a semiconductor cooling fin 140, a soaking plate 150, and a heat pipe. For example, the semiconductor cooling fin 140 may be connected between the insulating and heat-conducting member 110 and the charging electrode 210. The semiconductor refrigerating sheet 140 has high refrigerating efficiency, and can rapidly absorb and transfer the heat of the charging electrode 210 to the insulating heat conductive member 110, thereby reducing the temperature of the charging electrode 210. And then is directly transferred to the heat sink 120 by the insulating and heat conducting member 110, or transferred to the heat transfer member 130 by the insulating and heat conducting member 110, and then transferred to the heat sink 120 by the heat transfer member 130.

It should be noted that, the semiconductor cooling fin 140 can quickly reduce the temperature of the charging electrode 210, and due to the working principle of the semiconductor cooling fin 140, a part of heat is generated during the cooling process, but the part of heat generated by the semiconductor cooling fin 140 is not urgent to be dissipated through the heat sink 120. In actual operation, the semiconductor refrigeration sheet 140 does not need to be operated all the time, and can be started only before the risk of over-temperature occurs, and can be stopped after the temperature of the charging electrode 210 is rapidly reduced. After the semiconductor refrigerating fin 140 is arranged, the heat dissipation requirement on the heat dissipation fin 120 is lower, and the number or the size of the heat dissipation fin 120 can be reduced, so that the cost is saved, and the volume is reduced.

By providing the soaking plate 150, the soaking plate 150 can quickly reduce the temperature of the insulating and heat conducting member 110, thereby absorbing a large amount of heat of the charging electrode 210 and achieving the effect of quick temperature reduction.

The vapor chamber 150 has small volume, thin thickness, light weight, high thermal response speed, no need of external power supply and no need of special maintenance during working. The heat dissipation efficiency is high, the isothermal performance is good, and after the heat balance is achieved, the temperature difference between the evaporation section and the cooling section is small, and the heat dissipation efficiency can be almost regarded as zero.
