In Convective heat transfer the transfer of heat occurs from one place to another due to the movement of fluids, a process that is initiated by the transfer of heat via transfer. It is significant in many physical situations where Bulk motion of fluid enhances heat transfer, such as between a solid surface and the fluid. Thus the dominant form of heat transfer in liquids and gases is usually Convection., convection is usually used to describe the combined effects of heat conduction within the fluid (diffusion) and heat transference by bulk fluid flow streaming although sometimes discussed as a third method of heat transfer. This paper is about an investigation for a special V-Fin Array effecting the convective heat transfer.
