【Abstract】 おn the basis of heat transfer and flow friction performance for cross flow tube banks, and by the thermodynamic principle and the energy analysis of irreversibility the energy performance in the process of heat transfer of tube banks is studied. This work combined the heat transfer with flow friction to analyse the comprehensive utilization of energy and established the dimensionless equation, which can analyse the influence of structure parameters and working condition parameters. The paper takes spiral fin tube bank and smooth tube bank for example.更多还原
