RE: HX - surface area
I have never seen the tube area and the shell area added together to be called the "surface area of the exchanger". The only time that would matter is if you were having a coating applied to the tubes and shell and they were charging you by the square inch.

RE: HX - surface area
Surface area usually is limited to the tubes only, and if a U tube, only the straight tube portion. The bends are not considered, nor is the surface area of the tubesheet nor shell surfaces. If these help your heat transfer, then they are just lagniappe.
