Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat dissipation of charging piles, and in particular to a heat dissipation device for a charging pile. Background Art
[0002] The charging pile power module accumulates heat continuously under efficient operation, and factors such as high temperature in weather can easily cause components to exceed the safe temperature. Not only are working failures prone to occur, but in severe cases, it can even cause the charging pile to spontaneously combust, directly endangering personal safety. Therefore, cooling components are installed in the charging pile.
[0003] The traditional cooling method of charging piles is to use multiple cooling fans for heat dissipation, which has low heat dissipation efficiency. Moreover, once the cooling fan is used for a long time, outdoor dust can easily enter the charging pile with the air circulation, which not only makes the heat dissipation worse, but the dust may even contaminate other precision electronic components and affect charging. In addition, since the charging module is directly bonded to the radiator through thermal grease, the charging module and the radiator cannot maintain stable and sufficient contact, thereby reducing the thermal efficiency.

[0008] Furthermore, the air inlet holes are relatively arranged on both sides of the heat exhaust cavity, and the air outlet holes are connected to the back side of the heat dissipation cavity to prevent external air and dust from being directly introduced into the working cavity.

Finally, the spacing between the two liquid cooling plates is adjusted to a suitable position through the cooperation of the bolt and the locking nut, so that the charging module is fully in contact with the liquid cooling plate through the thermal grease.
[0010] Furthermore, the cooling pipe is in a vortex structure or a U-shaped structure or a U-shaped structure connected end to end, so as to increase the heat exchange area of the cooling pipe.
