Reylonds no. is a parameter which determine the nature of flow of fluid (laminar or turbulent). In heat exchanger design we need to know the Re no. for both tube and shell side in order to determine the heat transfer coefficient from Sieder Tate eq. for tube side and Donohue eq. for shell side.

In heat exchanger, reynolds no. is used only to calculate heat transfer coefficient.

By knowing Re number, we can calculate Heat transfer area, overall heat transfer coefficient, tube arrangement like square or triangular pitch based on fluid.

The Reynolds number is first used to understand what flow regime (i.e. turbulent, transition zone, laminar). It is then used to calculate the shell-side and tube-side film coefficients which are then used to calculate an overall U.
