Title:
METHOD FOR FORMING TEMPERATURE-RESPONSIVE HYDROPHILIC-HYDROPHOBIC CONVERSION SURFACE, AND TEMPERATURE-RESPONSIVE HYDROPHILIC-HYDROPHOBIC CONVERSION SURFACE AND HEAT EXCHANGER, USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/240203
Kind Code:
A1
Abstract:
The present invention relates to a temperature-responsive hydrophilic-hydrophobic conversion surface and a heat exchanger using same, and the temperature-responsive hydrophilic-hydrophobic conversion surface of the present invention has a surface property that is hydrophobic at a low temperature and is converted to be hydrophilic when the temperature rises. Accordingly, by applying the present invention to the fins of a heat exchanger, frost formation can be delayed in a low temperature environment due to the hydrophobicity, and remaining meltwater can be easily dried due to the conversion of the surface from hydrophobic to hydrophilic when the temperature is raised for defrosting. Therefore, according to the present invention, the surface property of the fins of a heat exchanger is automatically converted according to the temperature and exhibits only favorable advantages at respective temperatures, so that heat transfer performance and power efficiency of the heat exchange can be effectively improved.
