| dc.description.abstract | Thermal control is crucial for managing small electrical and electronic equipment. The most
effective method for thermal management is becoming recognized as a closed-loop pulsing
heat pipe (CLPHP). This experimental investigation aim is to find a CLPHP to compare the
thermal performance of CLPHP with two (copper and aluminum) different wire inserts. This
experiment uses ethanol, methanol, distilled water and acetone as working fluids. The impact
of employing pure water, methanol, ethanol and acetone as working fluids is investigated in
various filling ratios. A copper capillary tube with an inner diameter of 2.75 mm, has been
attached. The CLPHP contains six loops, each measuring 50 mm in length for the evaporation,
100 mm adiabatic, and 60 mm condensation sections. They were inserting Copper 0.9 mm wire
and Aluminum 0.9 mm wire. The experiment was conducted with Filling Ratio ranging from
40% to 60% and heat input varied between 10 to 60 watts. The findings are compared based
on evaporator temperature, condenser temperature, their differences, thermal resistance, heat
transfer coefficient, power input, and the impact of filling ratios. The ideal filling ratios for
ethanol, Methanol, distilled water and acetone are 60%, 40%, 40% and 40%, respectively, in
Copper and Aluminum wire inserts. High boiling fluid, i.e., distilled water and ethanol copper
wire insert, works as optimal performance. In comparison, comparatively low boiling points
fluid such as methanol and acetone aluminum wire insert deliverers most remarkable
