Study of pressure characteristics with heat transfer inside Oscillating Heat Pipe
The article focuses on the pressure characteristics inside single loop oscillating heat pipe (OHP) having 4.5 mm inner diameter copper tube with the loop height of 440 mm. Distilled water is used as working fluid inside the OHP with different filling ratios of 40％, 60％ and 80％ of total inside volume. Experimental results show that the thermal characteristics are significantly interrelated with pressure fluctuations as well as pressure frequency. And the pressure frequency also depends upon the evaporator temperature that is maintained in the range of 60°C to 96°C. Piezoresistive absolute pressure sensor (Model-Kistler 4045A5) has been used to take data. The Investigation shows the filling ratio of 60％ gives highest inside pressure magnitude at maximum number of pressure frequency at any of setting evaporator temperature and the lowest thermal resistance has been achieved at 60％ filling ratio.
