Plate-type heat exchangers are characterized as compact and highly efficient type for their ability to operate at higher pressure in comparison to the conventional heat exchanger. Further enhancement of such type can be implemented by augmenting the thermal properties of the base fluid such as the thermal conductivity and the heat transfer convention coefficient. This could be achieved by adding additive in nano-sized to the fluid. The present research addresses the influence of utilizing Aluminium Oxide and Titanium oxide on the performance and energy interaction with the environment of plate-type heat exchanger. Different volume fractions of the abovementioned nanofluid are experimentally investigated to reveal the relation of the exchanger effectiveness with the concentration of the nanofluid. Effect of Reynolds number of nanofluid is also reported. The results confirm that existence of nanofluid does enhance the performance of the heat exchanger remarkably. The exchanger effectiveness also ameliorates with augmentation in VoF of nanoparticle. Analysis of the results ascertains that the exchanger performance shows better enhancement when Aluminium Oxide is employed in comparison to Titanium oxide, particularly at large Reynolds number. The outcome of the analysis reports that 13% increment in the exchanger effectiveness when 3% of TiO2 nanofluid is used. In return, using same amount of Al2O3 nanofluid upgrades the exchanger performance by 23%. For the system/environment energy interaction, the results shows that 3% of Aluminium oxides augments the heat leak factor by 40% when Re ~12000 while the increment in the leak factor approach 45% for the case of Titanium oxide. Increasing the nanofluid flowrates to Re = 14000 results in ameliorating in the heat interaction for both nanofluid, though TiO2 is barely touch 50%.
