Title:

MEMBER FOR HEAT EXCHANGER, HEAT EXCHANGER, INDOOR UNIT FOR AIR CONDITIONER, OUTDOOR UNIT FOR AIR CONDITIONER, REFRIGERATOR, AND WASHER WITH DRYER

Document Type and Number:

Japanese Patent JP2023143804

Kind Code:

A

Abstract:

To realize a member for a heat exchanger with high efficiency while imparting characteristics not found in a metal itself with a coating with excellent heat transfer to a metal surface.SOLUTION: A fin 112 is made of metal, and has a carbon nanotube-containing oxide film 112B having a thread-like structure 112C on a surface of the metal when a cross section of the surface of the metal is observed with a scanning transmission electron microscope (STEM). The carbon nanotube-containing oxide film 112B contains carbon nanotubes in a direction in which a thermal diffusivity in a film thickness direction is higher than a thermal diffusivity in a film surface direction of the carbon nanotube-containing oxide film 112B.SELECTED DRAWING: Figure 3
