| Abstract: | the principle of field-coordinated enhancement of heat convection is presented that the better coordination between the velocity and temperature fields will lead a higher convective heat transfer coefficient, and the better coordination between the temperature fields of hot and cold fluids will lead a greater effectiveness of heat exchangers. Furthermore, applications of the principle of field-coordinated enhancement on upgrading the performance of heat exchanger are discussed. |

| Keywords: | Heat exchanger Heat transfer enhancement Field coordination |
