| Abstract: | In this paper,the heat transfer of a tube-shell type heat exchanger with two fluids'counter flow was analyzed.In the heat exchanger,the heat transfer tubes are square in-lined and filled with porous foam metal both inside and outside.And both the fluids flow in the porous foam metal are forced.The average theoretical equation of tube outside heat convection nusselt number has been obtained.And the overall heat transfer coefficient and the overall heat transfer area have been obtained,too. |

| Keywords: | porous foam metal tube-shell type heat exchanger heat convection overall heat transfer coefficient |
