The corrugated heat sink was neat, and I had already tried to figure out a
way to make that work. I do have some of the miracle brazing compound that
Ed found, and that would be perfect for joining the folded heat sink to the
inside and out of the pan. This may actually be the leading candidate at
the moment. Just a couple more thoughts I've had, Rusty.
Make the corrugated fin from really thin aluminum by weaving it through a stack of paint stir sticks, then drill 1/8" holes through it to increase airflow and surface area (lanced fin construction is what they call it). Take some of the "miracle brazing compound and smash it flat. I have one of the sheet metal working tools that would do an excellent job of it. Put the brazing strip between the fin and oil cooler box and put a rivet at each corner to hold it tight, then stick it in an oven to flow the brazing. The brazing can be run perpendicular to the fins to guaranteed solid attach points. The rivets may need extra brazing for a good seal.
Other thoughts:
The assembly might need to go in the oven at an angle so gravity will pull the brazing into the joints.
There will probably be issues with flux and subsequent cleanup.
The inside and out could be done at the same time.
Could the sticks be left in for the brazing operation? It would depend on the flow temperature of the brazing material, I guess.
