热交换器为化工、炼油、原子能和食品等工业部门所广泛应用的通用设备。对于化工、炼油工业尤为重要。如果以传统的指标热效率来评价热交换器,大多数是较理想的。但是,热效率仅仅是输出能量和输入能量的数量之比,所建立的功和热能的平衡也仅仅是数量之间的平衡。由于传递和转换过程中热能的输出 Heat exchangers are general-purpose devices widely used in industrial sectors such as chemical, oil refining, atomic energy, and food. It is particularly important for the chemical and refining industries. Most of the heat exchangers are ideal if they are evaluated with traditional index thermal efficiency. However, thermal efficiency is only the ratio of the amount of output energy and input energy, and the balance of work and thermal energy established is only a balance between the quantities. Due to thermal energy output during transfer and conversion
