碩士 === 淡江大學 === 航空太空工程學系碩士班 === 101 === This paper discusses numerical studies of the heat transfer characteristics at vertical heating state of a 3-D closed loop oscillating heat pipe(CLOHP), the parameters studied were working fluid filling ratio ,and inclination angle. A set of copper-tube CLOHP with internal diameter of 1.3mm,consisting of 4meandering turns and characteristic heat transfer length of 100mm was used in this study. The CLOHP condenser ,and evaporator section length both are 20mm,working fluid in this study was used water with filling ratio is 50% of total volume of the tube. The result shows that in this study the model ,numerical method which we chose can predict heat transfer mechanism of 3-D CLOHP, and with different filling ratios ,and inclination angles .Verticl heating modle and filling ratio is 50% compare with others inclination angles ,and filling ratio ,it heat resistance is the optimum.
