I'm not sure many of us are qualified to say. It's impossible to tell from that picture what the internal structure of that thing is. Based on the external structure, though, my guess is it won't work well at all. Looks like too much metal with too little surface area, and no apparent way to achieve decent airflow.
That's just conjecture on my part, though. But there's probably a reason you haven't seen other folks using similar designs....
