Leveraging this phenomenon, we develop a high-temperature dew point evaporative cooler capable of reducing hot airflow from 437 °C to below ambient temperature. The cooler also performs effectively below the boiling point, lowering inlet air from 43 °C to 16.7 °C. These findings open pathways for potential practical applications of dew point evaporative cooling in power generation, internal combustion engines, and generative AI systems.Nature communicationsHigh temperature evaporative cooler utilizing boiling suppression at water's boiling point.PMC1284804312402295W25310436237503312204082Vorobyev AYZheng JChen QLi YYan ZLiang ZFang RWei YSun ZPan NDeng YfalseHigh temperature evaporative cooler utilizing boiling suppression at water's boiling point.We experimentally demonstrate boiling suppression in a water film confined within superhydrophilic hierarchical nano/microstructured surfaces, enabling intense interfacial steam generation without bubble formation at the boiling point.
