  • Microfabricated passively and/or actively cooled apparatus for highly efficient, low cost atmospheric water generators
    Patent number: 10876276
    Abstract: An atmospheric water generation system with high efficiency is based on a counter flowing heat exchanger including multiple cold channels, each cold channel surrounded by multiple hot channels. The hot and warm gases flow in opposite directions, allowing the cool dry air to contribute to cooling the warm humid air to the dew point. Thermoelectric or passive cooling of the warm humid air, and hydrophobic surfaces in a cyclone structure also contribute in increasing the efficiency of the water generation system.
