U.S. Radiator Core Designs
________________
My reading of Pearce (
mitpress.mit.edu/books/structure-nature-strategy-design suggests that an aluminum small-scale
gyroid* fillled box would make an excellent radiator. Conventional radiators rely on a tube and fin arrangement that throttles heat transfer. As a gyroid reduces in scale, it increases in surface area.
Maybe one of our resident experts could run the numbers. I'm getting closer to being able to produce a test part. Tomorrow I have to find a local source for PLA filament.

* The gyroid separates space into two oppositely congruent labyrinths of passages. The gyroid has space group I4132 (no. 214).[5] Channels run through the gyroid labyrinths in the (100) and (111) directions; passages emerge at 70.5 degree angles to any given channel as it is traversed, the direction at which they do so gyrating down the channel, giving rise to the name "gyroid".
