人们在设计热交换器和分析热交换器的热性能时通常采用能量平衡的方法。该文利用效率分析热交换器的热性能，并在此基础上给出了热交换器的效率与其热负荷、换热管直径以及冷、热流体流速的关系。图５参８
Energy balance methods are commonly used when designing heat exchangers and analyzing the thermal performance of heat exchangers. In this paper, the thermal performance of the heat exchanger is analyzed by the efficiency of , and on the basis of this, the relationship between the efficiency of the heat exchanger and its thermal load, the diameter of the heat transfer tube and the flow rate of the hot and cold fluids is given.
