Description

Technical Field

[0001] This invention belongs to the field of charging pile technology, and in particular relates to a heat sink and heat dissipation component for electric vehicle charging piles. Background Technology

[0002] As energy replenishment devices for electric vehicles, the charging performance of electric vehicle charging piles directly impacts battery lifespan and charging time. Achieving rapid, efficient, safe, and reasonable power replenishment of the power battery is a fundamental design principle of electric vehicle chargers. With the rapid development of new energy electric vehicles, the demand for electric vehicle charging piles as energy replenishment stations is continuously increasing. Because charging piles are high-power energy conversion devices, the charging modules inside generate a significant amount of heat during charging. If this heat cannot be effectively dissipated, it will affect the lifespan of the charging pile components and may even pose safety hazards such as fires and explosions. Generally, a method is adopted where the heat-generating elements in the charging pile are tightly integrated with a heat sink. The heat sink rapidly dissipates the heat from the heat-generating elements, effectively cooling the charging pile.

[0003] Currently, most charging stations have ventilation holes on their outer casing for better heat dissipation. While this provides some cooling, it also makes them susceptible to moisture and dust, as well as short circuits or even fires caused by small rodents or insects damaging the cables inside the station.

[0004] In response to the aforementioned problems of moisture and dust, as well as the ease with which small rodents and insects can enter the charging station and cause accidents, this invention designs a heat sink and its heat dissipation components for electric vehicle charging stations. Summary of the Invention

[0005] The purpose of this invention is to provide a heat sink and its heat dissipation assembly for electric vehicle charging piles. Through the functions of the charging pile, heat dissipation assembly and heat sink, it not only achieves the function of ventilation and heat dissipation, but also has the effects of moisture and water resistance, dust resistance and rodent resistance. It solves the problems mentioned above, such as moisture and dust, as well as small rodents and insects that can easily enter the charging pile and cause accidents.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-9 As shown, this invention relates to a heat sink and its heat dissipation assembly for an electric vehicle charging pile, comprising a charging pile 1, a charging module, a heat dissipation assembly 2, and a heat sink 3; the charging pile 1 has a charging module for charging the electric vehicle and for the main heat-generating parts fixedly installed inside; a heat-conducting plate 4 is tightly attached to the charging module; a heat sink 3 is fixedly attached to the outer side of the heat-conducting plate 2, and a heat dissipation assembly 2 for ventilation and waterproofing is assembled on the outer side of the heat sink 3; the heat dissipation assembly 2 includes a ventilation pipe group 201 and a mounting clamp plate 202, and ventilation pipes 203 are evenly arranged in the ventilation pipe group 201; the mounting clamp plate 202 fixes the ventilation pipes 203 inside the charging pile 1; the heat sink 3 includes a heat dissipation base plate 301 and heat dissipation fins 302; heat dissipation fins 302 are evenly arranged on the outer side of the heat dissipation base plate 301; ventilation pipes 203 are fixed between the heat dissipation fins 302 on the heat dissipation base plate 301; the charging pile 1 adopts a closed shell.

[0033] Among them, such as Figure 3 and Figure 5 As shown, the ventilation duct 203 includes an air inlet duct 204 and an arc-shaped air outlet duct 205. The arc-shaped air outlet duct 205 is fixedly installed at the end of the air inlet duct 204, and the port orientation of the air inlet duct 204 is perpendicular to the port orientation of the arc-shaped air outlet duct 205. The air inlet duct 204 is a straight duct, designed to facilitate natural airflow for natural ventilation and heat dissipation, achieving a relatively low-efficiency heat dissipation effect, primarily used in winter and low-temperature periods. The port orientation of the arc-shaped air outlet duct 205 is perpendicular to the air inlet duct 204, allowing the arc-shaped air outlet duct to... The air outlet of the air duct 205 does not affect the air intake effect of the air inlet duct 204, nor does it have a mutually reinforcing effect. Each pair of adjacent ventilation ducts 203 are ventilation duct A2031 and ventilation duct B2032, respectively. The ports of the air inlet ducts 204 in ventilation ducts A2031 and B2032 face opposite directions, while the ports of the arc-shaped air outlet ducts 205 in ventilation ducts A2031 and B2032 face the same direction. A heat dissipation fin 302 is fixed between each pair of adjacent ventilation ducts A2031 and B2032.

[0034] Among them, such as Figure 5-9As shown, the ports of the air inlet duct 204 and the arc-shaped air outlet duct 205 both penetrate the charging pile 1 and are fixedly connected to the outside of the charging pile 1; the air inlet ports of the air inlet duct 204 located on both sides of the charging pile 1 are fixedly equipped with fan units 207; the side of the air inlet port of the air inlet duct 204 is provided with an air intake flare 206; the air intake flare 206 is an inclined structure 208; the bottom edge of the air inlet port of the air inlet duct 204 is provided with an air intake flare 209.

The fan unit 207 provides stable ventilation and heat dissipation effects for the air inlet ports of the air inlet pipes 204 on both sides of the charging pile 1, mainly used for heat dissipation mode in summer and high-temperature periods to ensure the cooling and heat dissipation effect inside the charging pile during charging. The air inlet flare 209 increases the inlet area of ​​natural wind and is not blocked by the fan unit 207, thereby improving the ventilation and heat dissipation effect.

The cooling fan 502 is fixedly installed on one side of the heat sink 3. When it is winter or during low temperature periods, the internal heat dissipation circulation component 5 dissipates the heat from the charging module and the heat conduction plate 4, which has a low power consumption heat dissipation effect.
