The invention relates to the technical field of aircrafts, in particular to a nacelle skin with a divergent enhanced heat transfer structure, which comprises a skin body, and a plurality of surface structure infinitesimal elements are arranged on the connecting surface of the skin body and a surface structure; the surface structure infinitesimal element comprises a plurality of protrusions, one protrusion is arranged corresponding to the jet flow holes of the flute-shaped pipe, and the other protrusions form a plurality of protrusion layers and are arranged around the protrusions corresponding to the jet flow holes respectively. According to the technical scheme, the technical problem that the heat exchange effect is affected due to the fact that the area, directly acting on the nacelle skin, of hot air sprayed out of the jet flow holes in the prior art is small can be effectively solved.
本发明涉及飞行器技术领域,尤其涉及一种具有发散状强化换热结构的短舱蒙皮,包括蒙皮本体,蒙皮本体与表面结构的连接面具有多个表面结构微元;表面结构微元包括若干凸起,其中一个凸起对应笛形管的射流孔布置,其它凸起形成若干凸起层,并分别环绕于与射流孔对应的凸起布置。本发明通过上述技术方案,可以有效解决相关技术中从射流孔喷出的热气直接作用在短舱蒙皮上的面积较小,影响换热效果的技术问题。
