One of the most important techniques of the convective process is by means of fins, which have a significant impact in the manufacture of cooling and heat transfer transformers used in many of the devices used. These fins have the ability to increase the area of heat transfer as they work on turbulence of the fluid used and thus increase the process heat transfer. In this research paper, the presence and distribution of fins in a mini-channel and irrigation system were studied to improve heat transfer in it. The effect of this disturbance on the deformation and stress affecting the fins was studied. The results showed an improvement in heat transfer in the use of distributed fins.
