A 3D-printed ceramic phone case promises to solve two problems at once: phone overheating and the discomfort of pressing it against the skin during long calls. Its passive heat sink draws heat away from the device and, when in contact with the chest, also cools the user. A simple object with a dual function that prevents sweat and hot screens.
Porous ceramic and passive cooling geometry 🧊
The design uses a structure of internal channels made from high thermal conductivity ceramic. When the phone is held, heat transfers from the battery and processor to the outer surface of the case. If the user holds it against their chest, the material acts as a heat exchanger: it absorbs heat from the phone while simultaneously drawing body heat through direct contact. It requires no fans or liquids, only the temperature difference between the two bodies. 3D printing allows customization of the porosity to optimize thermal flow without adding excessive weight.
The invention that turns your chest into a radiator 🔥
Now you can have a cool phone while your torso cools down. It's like having a PC heat sink embedded in the case, but without RGB or noisy fans. If you used to sweat after talking for ten minutes, now you can go for half an hour and feel like you're near an air conditioner. The downside: if you call in winter, you might prefer a wool case. Progress has these paradoxes.
