I do something similar, and I use a snippet like this

#+begin_src emacs-lisp
  (defun the-in-the-org-lib-p ()
    (and (f-this-file)
         (f-child-of? (f-this-file) the-org-lib-directory)))

  (defun the-org-lib-hook ()
    (if (the-in-the-org-lib-p)
          (setq-local org-babel-default-header-args:emacs-lisp
                      `((:tangle . ,(f-expand (f-swap-ext (f-filename 
(f-this-file)) "el") the-lib-directory))
                        (:noweb . "yes"))))))

    (add-hook 'org-mode-hook 'the-org-lib-hook)

`the-org-lib-directory' points to where all my Org config sources are,
while `the-lib-directory' points to where the tangled files go. My Org
files then have a structure like


* Configuring Whatever Features
** Requirements :noexport:
#+begin_src emacs-lisp
  ;; -*- lexical-binding: t; -*-
  ;;; whatever.el --- Whatever functionality
  (require 'whatever)
** Some Subfeature
Explain how we use the feature
#+begin_src emacs-lisp
  (my-configuration 'stuff)

** Provides :noexport:
#+begin_src emacs-lisp
  (provide 'whatever)

  ;;; whatever.el ends here

I have some additional configuration to tangle my lib files on save, and
to regenerate the top-level documentation so that (in theory) the README
is always up to date with the configuration. The :noexport: tags remove
the noise of require and provides when I export.
