Abstract

PROBLEM TO BE SOLVED: To remove water droplets generated by dew formation at a cooling panel provided with a thermo-electrical element. SOLUTION: A cooling panel 1 is comprised of an N-type semiconductor 2a, a P-type semiconductor 2b, a metallic plate electrode 3, an electrical insulator 5, a thermal conductor 6 and a thermal insulating member 7. A hydrophobic film 8 is fixed to a cooling side (a heat absorbing) side of the panel 1. It is possible to remove water droplets formed as dew at a cooling surface due to water repelling characteristic of the hydrophobic film 8.
