本文报道了一种具有高效滴状冷凝传热（DCHT）性能的铜基镍基纳米锥薄膜，该薄膜可以通过简单的电沉积和低表面能化学改性来制备。与平面铜样品相比，我们的纳米样品显示冷凝液微滴自推进（CMDSP）功能和超过89%的DCHT系数增强。这种显着的增强可能归因于表面纳米结构诱导的CMDSP功能以及纳米膜的原位集成和可折叠性的合作。这些研究结果对设计和开发先进的DCHT材料和器件，提高热管理效率和能源利用率具有重要意义。
We report a type of copper-based ultrathin nickel nanocone films with high-efficiency dropwise condensation heat transfer (DCHT) performance, which can be fabricated by facile electrodeposition and low-surface-energy chemistry modification. Compared with flat copper samples, our nanosamples show condensate microdrop self-propelling (CMDSP) function and over 89% enhancement in the DCHT coefficient. Such remarkable enhancement may be ascribed to the cooperation of surface nanostructure-induced CMDSP function as well as in situ integration and ultrathin nature of nanofilms. These findings are very significant to design and develop advanced DCHT materials and devices, which help improve the efficiency of thermal management and energy utilization.
