The heat transfer and fluid flow in the parallel-plate channels with transverse fin arrayswas investigated numerically. The influences of the configuration and the thermal conduc-tivity of the fin on the characteristics of heat transfer and fluid flow were considered. It wasfound that in the range of Re = 300 ~ 800, the heat transfer of the channels was enhancedgreatly compared with the smooth channel. Small fin thermal conductivity will deterioratethe ability of enhancing heat transfer.
