HEAT EXCHANGER MEMBER, HEAT EXCHANGER, AIR CONDITIONER INDOOR UNIT, AIR CONDITIONER OUTDOOR UNIT, AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2022/196497
Kind Code:
A1
Abstract:
The present invention realizes a highly efficient heat exchanger member while using a coating having excellent thermal conductivity to impart, to a surface of a metal, properties that the metal itself does not possess. The heat exchanger member comprises a metal, and has, on the surface of the metal, a carbon-containing hydrated oxide film (112B) provided with fine irregularities (112C). The average spacing between the vertices of the protrusions of the fine irregularities (112C) is 20-120 nm, inclusive, and the average value of the difference in height between the vertex of a protrusion and the nadir of a recess that are adjacent to each other is 10-250 nm, inclusive. In addition, at least a portion of the surface of the carbon-containing hydrated oxide film (112B) is constituted by a hydrated oxide.
