Three flat plate heat pipes in different size was chosen to match the size of heat sink and compared each other. The heating area (evaporator section) of flat plate heat pipe (FPHP) made the discussion, the experimental results show the thermal resistance value of large-size (8370 mm2) less than that of small-size (2773 mm2). When some area of condenser section of flat plate heat pipe did not contact heat sink, the heat can’t be take the away effectively. For the sake of heat accumulation, the thermal resistance of heat sink module was increased; therefore, the size of heat sink should be carefully chosen to match the heat dissipation performance of flat plate heat pipe. Three copper powders, the gas-atomized copper powder (GA), water-atomized copper powder (WA), oxide reduced copper powder (OR) were used to sintering the wick of FPHP, respectively. The thermal performance of wick structure using GA copper powder is the best among three powders. Advisor Committee Liu-Ho Chiu - advisor
