PDMS is used as the substrate of flexible flat plate heat pipe. The flexible flat plate heat pipe can be arbitrary bent in repetition without causing permanent damages due to excellent mechanical properties of PDMS. The silicon wafer is used as the mold with conjugated micro-structures. Then, the PDMS fluid was cast on the silicon mold to form the substrate of the flexible flat plate heat pipe. The flexible flat plate was completed after filling of adequate working fluid inside. The micro-structure in the heat pipe is used as the wick structure, and the working fluid flows by capillary force along the wick structure in heat circulation. The mechanical properties and the variations of the working fluid inside the flexible flat plate heat pipe have been measured.口試委員會審定書 i 謝 ii要 iiibstract ivist of Figures viiist of Tables xhapter 1 Introduction 1hapter 2 Principle of heat pipe 11hapter 3 Materials 13hapter 4 Meniscus wick structure 15-1 Introduction 15-2 Fabrication 16-2-1 Heat pipe Configuration 16-2-2 Mold Fabrication 17-2-3 Heat pipe Fabrication 20-3 Experimental procedure 21-4 Discussions 23-5 Conclusions 24hapter 5 Trapezoid wick structure 25-1 Introduction 25-2 Fabrication 26-2-1 Heat pipe configuration 26-2-2 Fabrication preparation 28-2-3 Heat pipe fabrication 30-3 Experimental procedure 31-4 Result 34-4-1 Discussion – radius of curvature R 36-4-2 Discussion – capillary pressure difference 39-5 Conclusion 42hapter 6 Triangular wick structure 43-1 Introduction 43-2 Fabrication 44-2-1 Heat pipe configuration 44-2-2 Process preparation 46-2-3 Heat pipe fabrication 47-3 Experiment procedure 49-4 Result 54-4-1 Discussion – radius of curvature R 57-4-2 Discussion – capillary pressure difference 59-5 Conclusion 62hapter 7 Future work 63eference 64ppendix 692961622 bytesapplication/pdfen-US可撓式平板型熱管毛細結構工作流體毛細力熱循環Flexible flat plate heat pipewick structureworking fluidcapillary forceheat circulationthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/187267/1/ntu-98-R95522522-1.pdf
