折边翻折后于左侧板和右侧板上形成连通侧板两侧空间的散热口，供气体进出两侧板之间的空间以对功率模块进行散热。After the folded edge is turned over, heat dissipation openings are formed on the left side plate and the right side plate to communicate with the space on both sides of the side plate, allowing gas to enter and exit the space between the two side plates to dissipate heat from the power module.
其有益效果在于：在左、右侧板上加工内翻的折边，利用折边来承载功率模块，利用加工折边所形成的开口来作为供气体流通的散热口。其中，折边与两侧板为一体式结构，在支撑功率模块的两侧或与承载体连接时具有较高的强度，能够满足支撑功率模块的要求，保证充电功率模块安装箱使用时的稳定性；设置的散热口增加了空气进入充电功率模块安装箱的路径，提高了空气在充电功率模块安装箱中的流通性，在充电功率模块安装箱中形成了多个分别对功率模块进行散热的分支风道，保证了充电功率模块安装箱的散热性能。操作人员可以通过形成折边的这一次加工来同时实现对功率模块的支撑及散热，结构简单，便于加工。The beneficial effect is that inwardly turning folded edges are processed on the left and right side plates, the folded edges are used to carry the power module, and the openings formed by the processed folded edges are used as heat dissipation ports for gas circulation. Among them, the folded edge and the two side plates are of an integrated structure, which has high strength when supporting the two sides of the power module or connecting with the carrier, which can meet the requirements for supporting the power module and ensure the stability of the charging power module installation box when used. The heat dissipation port provided increases the path for the air to enter the charging power module installation box, improves the circulation of the air in the charging power module installation box, and forms a plurality of heat dissipation for the power module in the charging power module installation box The branch air duct ensures the heat dissipation performance of the charging power module installation box. The operator can support and dissipate heat for the power module at the same time through the process of forming the folded edge. The structure is simple and easy to process.
进一步的，所述折边沿水平方向延伸。Further, the folded edge extends along the horizontal direction.
其有益效果在于：将折边沿水平方向延伸布置，利用折边支撑功率模块时，折边可以作为供功率模块滑入充电功率模块安装箱内的轨道，操作人员只需通过简单的推拉动作就可以使功率模块安装到位，简化了充电功率模块安装箱的结构，又减少了操作人员的任务量。The beneficial effect is that the folded edge is extended and arranged in the horizontal direction, and when the folded edge is used to support the power module, the folded edge can be used as a track for the power module to slide into the charging power module installation box, and the operator only needs to push and pull the power module. The power module is installed in place, the structure of the charging power module installation box is simplified, and the workload of the operator is reduced.
进一步的，所述折边为向上翻折而成的上翻折边。Further, the folded edge is an upward folded edge formed by folding upwards.

At the same time, the folded edge is located at the upper edge of the heat dissipation port. The folded edge is turned inward by external force during processing, and the folded edge is affected by the gravity of the power module during use and has a tendency to fold outward. At this time, the original inversion posture will resist the movement trend of valgus, so that the folded edge maintains a stable inversion state to support the power module.
进一步的，充电功率模块安装箱上于折边的后方设置有供充电桩中散热风扇伸入的空间。Further, the charging power module installation box is provided with a space behind the folding edge for the cooling fan in the charging pile to extend into.
其有益效果在于：在充电功率模块安装箱中预留有供散热风扇伸入的空间，能够减少冷却用气流的流动路径，加快循环速度，提高散热效果。The beneficial effect is that a space is reserved in the charging power module installation box for the cooling fan to extend in, which can reduce the flow path of the cooling air flow, accelerate the circulation speed, and improve the heat dissipation effect.
进一步的，充电功率模块安装箱还包括连接在左侧板和右侧板之间的底板，底板上设置有连通底板两侧的透气孔。Further, the charging power module installation box also includes a bottom plate connected between the left side plate and the right side plate, and the bottom plate is provided with ventilation holes communicating with both sides of the bottom plate.
其有益效果在于：充电功率模块安装箱中设置底板能够拉紧左右侧板，保证充电功率模块安装箱整体的连接强度。底板上设置的透气孔增加了空气对于充电功率模块安装箱的流通性，并且透气孔能够对上升的气流进行避让，使热气流通过对功率模块进行散热的冷却气流带走，减少热量在充电功率模块安装箱底部的堆积，保证散热的效果。The beneficial effect is that: the bottom plate set in the charging power module installation box can tighten the left and right side panels, ensuring the overall connection strength of the charging power module installation box. The ventilation holes set on the bottom plate increase the circulation of air to the charging power module installation box, and the ventilation holes can avoid the rising airflow, so that the hot airflow can be taken away by the cooling airflow that dissipates heat from the power module, reducing the heat in the charging power module.

With such a structure, the top of the power module 90 located below the folded edge 50 can be closer to the heat dissipation port 60, and the power module The top position of 90 is generally the position where heat gathers, making it closer to the heat dissipation port 60, which can shorten the path of heat exchange and improve the efficiency of heat dissipation. Moreover, the location of the folded edge 50 at the upper edge also has the advantage that the folded edge 50 is turned inward by an external force during processing, and the folded edge 50 is affected by the gravity of the power module 90 when it is used. At this time, the original inversion posture will resist the movement tendency of valgus, so that the folded edge 50 maintains a stable inversion state to support the power module 90 .
