Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to circuit breakers, and in particular to a graphene heat dissipation structure of a heat dissipation charging pile. Background Art
[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles at different voltage levels. Due to the needs of modern life, the demand for charging piles is increasing.
[0003] As more and more people use charging piles, the charging piles are in working condition most of the time, and a lot of heat is generated inside the charging piles. The charging piles need good heat dissipation effect, especially in the summer when the temperature is high. If the heat cannot be dissipated in time, it will affect the use of the charging piles.
[0004] The DC module is the core component of a charging pile and directly determines its operational reliability. Traditional DC modules use silicone grease as the filler between the heat-generating components and the heat sink. Due to the low thermal conductivity of silicone grease, the electronic components within the DC module can easily overheat, forcing the charging pile to operate at a reduced rating and, in severe cases, even burning out the DC module. Utility Model Content
[0005] In order to solve the defect in the existing technology that when silicone grease is used as the filling medium between the heating device and the radiator, the electronic devices in the DC module are easily heated up, causing the charging pile to be forced to operate at a reduced rating, and in severe cases even burning the DC module, the utility model provides a graphene heat dissipation structure for the heat dissipation charging pile.
