Abstract:
With the development of miniaturization, integration and high power of electronic devices and their urgent need for technologies enabling to solve high heat flux density dissipation at small-scale space, research on high-efficiency condensation heat transfer (CHT) interface materials has attracted widespread attention. Compared with filmwise condensation, dropwise condensation is a type of more efficient heat transfer way. However, discrete condensate drops on ordinary hydrophobic flat surfaces only can depart under gravity with relatively higher drop thermal resistance and slower renewal frequency, which is disadvantage to CHT. Clearly, how to realize high-density self-renewal of small-scale condensate microdrops for more efficient energy transport has become current research focus. So far, great breakthrough has been made in the development of bio-inspired surfaces for enhancing CHT, including superhydrophobic surfaces mimicking cicada wings, hydrophilic-hydrophobic hybrid surfaces mimicking desert beetles and super-slippery surfaces mimicking the peristome of pitcher plants. In this review, we briefly summarize their latest progress and respective issues, which are helpful to develop high-efficiency CHT interface materials for phase-change-based heat dissipation devices.
