Abstract

This research article deals with design and experimental study of three-stage cascade heat pipe for electronic device and energy storage device like super and ultra-capacitor. Suitable materials of primary and secondary fluids for single and cascade heat pipe was selected and fabricated given dimensions. The both single and multistage experiment conducted with different loads. The cascade heat pipe focused to two different fluid combination and experiment results acquired and discussed. The experiment was conducted with three different heat inputs like 40 to 200 W. The axial temperature was measured for both single and multistage and integrated with NI DAQ Data Logger. The experiments attained steady state temperature for each stage after 35 seconds. Thermal resistance, heat transfer co-efficient were predicted for both single and multistage.  Both single and multistage heat pipe Pressure measured by using piezo electric pressure transducer and integrated. Suitable working range of 40-200 0C was predicted by experimentally. Merit number of primary fluid (water is 4.26x10) 25 times higher than ethanol merit number 166.3x106 and acetone merit number, but latent heat of evaporation of ethanol was higher compared to water. Based on this experimental research, cascade heat pipe efficiency was higher than compared to single stage. Heat pipe working range (40to 220 deg C) was suitable for energy storage devices.
