New manufacturing techniques could improve heat exchangers in everything from air conditioners to massive ships.

With this in mind [Advanced Engineering Solutions] created a metal 3D printed heat exchanger that is half the size and four times the efficiency of the one it was designed to replace. Video after ...

“With our present work, we can 3D print exactly the needed shape of thermoelectric materials,” says Xu. “The resulting devices exhibit a net cooling effect of 50 degrees in the air, matching ...
