Let's have a talk on flow of fluids in Heat exchangers!
In my view, we prefer counter current because temperature gradients in hot and cold fluids are maintained at a large value. This gives us higher efficiency at a small heat transfer area. Secondly, counter-current maintains a (almost constant) declining temperature gradient.
