Condensation or frost suppressing carrier and heat exchanger having the same

摘要

To provide a dew condensation or frost suppressing carrier enabling highly efficient and stable cooling on a heat exchange surface and a heat exchanger having the carrier.SOLUTION: It is possible to provide a maintenance-free heat exchange surface by preventing mass transfer on the heat exchange surface S having a large temperature difference from the surroundings, and it is possible to cool the moist air through the heat exchange surface , In the case of absorbing heat from moist air below freezing point in the temperature boundary layer BL, it is preferable that in the temperature boundary layer determined in accordance with the temperature Tout of the cooling heat exchanging surface S and the airflow caused by the humid air in contact with the humid air, A carrier C having a thickness at least partly arrangeable and having a thermal conductivity higher than that of moist air by opposing to the exchanging surface so as to condense steam in the humid air or sublimate Thereby dehumidifying the humid air, thereby suppressing condensation or frost formation on the cooling heat exchange surface.BACKGROUND OF THE INVENTION
