Let's do the Gyroid again



I'd had prior exposure to Peter Pearce's Structure In Nature..., so when I run the 3D slicer software and saw a gyroid fill, I immediately understood that it subdivides a space into two equal, interpenetrated volumes.

Structure in Nature Is a Strategy for Design by Peter Pearce - Goodreads
the structural designs that occur in nature--in molecules, in crystals, in living cells, in galaxies--is the proper source of inspiration, peter pearce affirms, for the design of man-made structures.nature at all levels builds responsive and adaptive strategies that conserve material and energy resources through the use of modular components …
I'd picture a rectilinear box with inlets and outlets in the corners, but as it occurs, the optimal shape is a spindle/football shape.

Lattices on the outside, and on the inside as a permanent support structure for terminating the gyroid. Half the weight and four times the performance of the hand-crafted part.

This would look awesome on the firewall of a 1932 Ford highboy roadster, would it not? An oil cooler that pre-heats the fuel?

One of the advantages of the gyroid fill is less pressure drop across a heat exchanger. What might that mean to an Ecomodderer?

Unpressurized ICE engine radiators are limited to 212 degrees F., IDK about pressurized systems. The lower pressure drop on the air side would reduce the overall drag of the vehicle. The lower pressure drop on the water side would reduce the load on the engine.

The FDM materials of choice would be Polycarbonate or ABS. Parts can be autoclaved, up to 260 degrees or thereabouts.

Limited print bed size suggests twin radiators, like Porsche uses.
