| Abstract: |
| Functional surface structures for heat transfer refers to the structures with different morphology, scales and dimensions processing on a solid surface for heat transfer. The complex functional surface structures have wide application prospects on the thermal control of highly–integrated chip. How to actively design the functional surface structures according to heat requirements and propose suitable high–efficiency low–cost manufacture method is the key issue for solving the problem of high heat flux. Based on analyzing the research on present state of functional surface structures for heat transfer, the key manufacture techniques of functional surface structures are discussed in detail. Furthermore, the priority research areas for the future study of functional surface structures are brought forward, which aim to the micronization and complication of surface structures, and high–performance low–cost manufacture methods. |
