摘要
文中根据换热器效率的概念,即冷流体获得的能量与热流体放出的能量之比,提出换热器效率-单元数设计方法,得出顺流和逆流状态两种基本流型下的效率坐标图,并利用该方法进行实际算例计算。
In this paper, based on the concept of the efficiency of the heat exchanger, that is, the ratio of energy of cold fluid obtained and hot fluid released, a design method for heat exchanger ( η - NTU) has been propose, and the efficiency plot has been obtained under two basic flow patterns of the downstream and upstream states. Finally, the practical example has been done using this method.
