The heat transfer characteristics of the heat
transfer devices can be enhanced by changing the properties and
flow features of working fluids. In this regard, heat transfer
characteristics of a two–phase closed thermosyphon (TPCT) with
clinoptilolite/water nanofluid are experimentally determined for
3 different particle size of clinoptilolite nanoparticles, that is 50
nm, 340-370 nm and 450-500 nm, respectively. The TPCT is
fabricated from the copper tube with the 13 mm inner and 15
mm outer diameters, whereas the length of it is 1 m. The
experimental work was carried out under different operating
conditions ranging from 200 W to 400 W and 5 g/s to 10 g/s for
the heater power and coolant mass flow rate, respectively. The
input parameters such as effects of mass flow rates of cooling
water, heater power and thermal resistance of the TPCT were
investigated. It is observed that the efficiency of the TPCT
increases when clinoptilolite/water nanofluid was used as the
working fluid instead of deionized water. Moreover, the
maximum enhancement in the thermal performance was
obtained as approximately 16% for all conditions in the
experiments in which TPCT was charged with the nanofluid as
the working fluid.
