The study investigates, by calculations, some ways to improve the thermal efficiency of plate heat exchangers (PHEs) used in vegetable oil processing industry. performance these is limited transfer rate side and low conductivity material. starts from a base case with oils cooled water exchangers, all chevron angle 30° different number channels areas. change one geometrical characteristic plates, namely angle, 45° then 60°, led significant increase overall coefficients 16.0% when changing 28.1%, on average, increasing 60°. This accompanied rise pressure drops circuits, but values are acceptable since they do not exceed 1 bar circuit 1.4 cold fluid circuit, respectively. use Fe3O4–SiO2/Water hybrid nanofluids concentrations 0.5% v/v, 0.75% 1% v/v were investigated replace cooling water. An 2.2% average was noticed using nanofluid comparatively water, which large adds increase. A supplementary 2.6% possible manufacturing material for plates aluminum alloy 6060 also adding performances obtained previous modifications. total sets modifications can 34.2% average. Thus, design new PHEs, miniaturization equipment becomes possible.
