图15 (a)传统蒸发池的示意图，入射的阳光被体相吸收，使整体水温上升，实现蒸发;(b)提出的太阳伞的示意图，它将入射的阳光转换为中红外辐射，其中水的吸收能力很强，从而提高了表面温度和蒸发速率，而整体保持在较低的温度; (c)太阳伞和水的能量平衡和传热模式，红色区域表示表面非接触的热局部化;(d)非接触式太阳能蒸发器的示意图[73-74]

Fig.15 (a) Schematic of a conventional evaporation pond where incoming sunlight is volumetrically absorbed，causing a bulk water temperature increase that achieves to evaporation; (b) the proposed solar umbrella converts incoming sunlight into mid-infrared radiation where water is strongly absorbing，thereby increasing the surface temperature and evaporation rate while the bulk remains at a lower temperature; (c) energy balance and modes of heat transfer for the umbrella and water，the red region represents non?contact heat localization at the surface; (d) schematic of the contactless solar evaporator(after ref.[73-74])
