The invention belongs to the technical field of aluminum alloy forming machining, and discloses a multifunctional aluminum alloy hollow structure wallboard which is an arc-shaped active hollow cooling wallboard, longitudinal flow channels are formed in the hollow cooling wallboard side by side, necking throttling holes are formed in the two ends of each longitudinal flow channel, the ends of the necking throttling holes correspondingly communicate with annular confluence channels on the two sides of the hollow structure wall plate, and confluence ring frames are arranged on the outer sides of the annular confluence channels on the two sides correspondingly. The multifunctional hollow structure wallboard is formed at a time through the penetration welding and superplastic forming composite technology, the multiple functions of converging, throttling and rigidity increasing can be achieved, the sizes of the throttling holes and the cooling channels can be designed according to requirements, and the design freedom degree is high.

    本发明属于铝合金成形加工技术领域,公开了一种多功能铝合金空心结构壁板,所述空心结构壁板为弧形主动空心冷却壁板,空心冷却壁板上并排设置有纵向流道,纵向流道的两端设置有缩颈节流孔,缩颈节流孔的端部对应连通空心结构壁板两侧的环向汇流通道,两侧环向汇流通道的外侧分别设置有汇流环框。本发明将多功能空心结构壁板采用穿透焊接与超塑成形复合工艺实现了一次成形,可实现汇流,节流和增加刚度多重功能,节流孔及冷却通道其大小可根据需求进行设计,设计自由度高。
