【 摘 要 】

An experimental study was performed on Oscillating Heat Pipe (OHP) with closed loop structure. The capillary tube made up of copper of this OHP has inner diameter of 2.15 mm and thickness of wall is 1 mm. Different set of experiments were performed with filling ratios ranging from 30% to 100%, heating power ranging from 115 to 430 W at evaporator section and free convection condition at condenser section. The water has been considered as a working fluid. The thermal resistance was calculated for measuring the thermal performance of OHP. The changes in thermal resistance with heat input for various filling ratios has been carried out. The thermal resistance achieved lowest for 70 % filling ratio.
