3-D natural convection heat transfer in a vertical parallel channel with protruding single module was investigated numerically. The particular interest was in the removal of thermal energy from the module by convective heat transfer. The commercial code based on the finite volume method, PHOENICS was used to obtain velocity vectors and temperatures. Heat transfer characteristic was promoted at the lower corner of the module and was decreased at the upper corner due to recirculation zone. For the range of 8.28×10³ < Ra^(*)_(c) < 3.48×10^(6), a useful correlation of mean Nusselt number was proposed as a function of modified channel Rayleigh number. In addition the temperature of the module surface was strong1y affected by channel ratio and with the increasing channel ratio, the effect was decreased.
