Abstract

Heat exchanger is an equipment used to move heat between two fluids or more without the occurrence of mixing (direct contact) between the fluids. The purpose of this research is to know the effect of cold fluid mass flow rate to cold temperature change of fluid, change of heat rate received cold fluid, total heat transfer coefficient, cold fluid heat transfer coefficient, heat exchanger efficiency, and change of curing load mass in the form of cassava at heat exchanger cross flow 2 rectangular fin tube and heat exchanger cross flow 4 rectangular fin tube. The flow of this heat exchanger is a cross flow, where cold fluid is flowed to the heat exchanger through the tube. The cold fluid will receive the heat from the hot fluid generated from the LPG gas combustion process. Hot fluid is flowed on a heat exchanger shell. The cold fluid that has been flowed in the heat exchanger tube and receives the heat will go out to the drying machine used to dry the cassava as a drying load. In heat exchanger cross flow 2 rectangular fin tube, the optimum result is obtained in cold fluids with mass flow rate of 0.022 Kg / s with the change of cassava mass of 0.2 Kg, the heat rate received by cold fluida of 2755.3 watt and efficiency of heat exchanger 49.9%. In the heat exchanger cross flow 4 rectangular fin tube, the optimum result is obtained in cold fluid with a mass flow rate of 0.023 Kg / s with a change of cassava mass of 0.21 Kg, heat receiving rate of 3858.3 watt, and heat exchanger efficiency of 69.9%.
