Abstract: 
n this study, the comparison of the heat transfer of heat exchanger of the spiral tube and the direct pipe using the hybrid nanofluid in the turbulent flow has been empirically investigated. The nano fluid used in this study consists of a mixture of titanium oxide, silicon oxide and magnesium oxide with a medium diameter (20-30 nm) in a base water fluid at a temperature range of 60 to 30 ° C. Nanoparticles have been used in the volume fractions range of 0. 25, 0. 5, 0. 75 and 1%. The results showed that the Nusselt number increased by increasing the Reynolds number and the concentration in the spiral tube compared to the direct tube by 6. 6% on average. Also, the results are reported as temperature difference, the use of nanoparticles in the spiral tube is higher than the direct tube in the volume fraction of 0. 25% and the temperature of 60 ° C, 37. 6%. The percentage increase in the optimal temperature difference of the hybrid nano fluid in the spiral tube in the volume fraction is 0. 25% and 60 ° C, which is 10% higher than the base fluid and in the direct tube in the volume fraction of 0. 75% and 60 ° C Compared to the base fluid, the temperature difference is increased by 6%.
