According to the low efficiency of the organic heat transfer material heater, this paper studies the heat transfer process under temperature difference in the organic heat transfer material heater with the finite time thermodynamics, derives the calculation formula and characteristic parameter x to determine the minimum temperature difference with the minimum exergy loss. Based on this, this paper proposes that the characteristic parameter x can be used as the optimization criterion of energy-saving and to judge the energy utilization efficiency of the organic heat transfer material heater, fu...
