Since 2020, the new energy vehicle industry has entered a fast-lane development stage. With the implementation of the country's new infrastructure policy, the era of new charging piles has officially opened. Since the construction of new energy vehicles and charging piles has been included in the scope of new national infrastructure this year, the construction of charging piles has set off a new upsurge, and the charging pile industry will usher in a period of development.
Charging pile is an indispensable charging equipment for new energy vehicles, and its quality directly affects the safety of charging. Stable performance, safety and reliability have become very important indicators for charging piles. This paper focuses on the protection design of the ventilation and heat dissipation shell of the charging pile.
The most important power module in a charging pile is the AD-CD power module. The power module generates a lot of heat during operation and requires effective ventilation and heat dissipation. If heat accumulates in the cabinet and is not dissipated effectively, it will seriously threaten the operation of the power module. If the temperature is too high, the power module will burn out due to the high temperature, or even **even**. Therefore, the research on the ventilation and heat dissipation of charging piles has become the top priority in the research and development process of charging pile manufacturers.
At present, almost all charging pile manufacturers in China use forced air cooling to effectively ventilate and dissipate heat from charging piles. Install a dry air cooler in the cabinet for exhaust, and then open the ventilation shutters on the charging pile cabinet, such as left in and right out, to form forced circulating air, that is, cold air outside the cabinet enters, hot air comes out, and the cabinet is drained. Bring heat to the outside to dissipate heat and cool down. This forced air cooling method is currently the most economical and mature cooling solution for charging piles, so almost all charging pile manufacturers have adopted the same design route.
