Present paper reports theoretical analysis of Spiral heat exchanger(SPHE) and Gasketed plate heat exchanger (PHE), to investigate its efficacy of heat transfer. Experimental investigation of effect of chevron angle of plate in Gasketed PHE on thermal and hydraulic performance is carried out. The Spiral heat exchanger when compared with Gasketed plate heat exchanger (PHE), the performance of PHE is found better than SPHE. Overall heat transfer coefficient (U) is increased by 86.8% by GPHE over SPHE. Performance of PHE is investigated for two different plate chevron angles, 65° and 30°. Overall heat transfer coefficient is increased by 26% for chevron angle 65° as compared to 30°. Also, pressure drop is increased by 12.77% when chevron angle increased from 65° to 30°.
