Finned tubes are able to even out the heat transfer between the inside of the tube and the outside. When the heat transfer coefficient on the outside of the tube is significantly lower than the heat transfer coefficient on the inside of the tube, there is a major advantage to incorporate fins on the outside tube surface to take full advantage of the high heat transfer rate on the inside of the tube.
By using a finned tube with eight times as much surface on the outside of the tube, the total length of the tube required for heating the viscous oil can be reduced by one sixth, Fins are basically external surface on tube for increasing the surface area of the bare tube, resulting in a compact heat exchanger.

more surface area per square feet of heat exchanger
lower air resistance, resulting in less power to deliver the requires c.f.m.
reduction in number of tubes for given b.t.u. Transfer per rate area, resulting in fuel saving
light weight easier handling
more fins per inch can be incorporated on entire tube length
