Document Type and Number:
Japanese Patent JP7291983
Kind Code:
B2
Abstract:
A heat exchanger member, a heat exchanger, a heat exchanger, and a cooling system that are highly efficient are realized by providing, to a surface of a metal in contact with a refrigerant, of a heat exchanger used for a cooling unit and a heat dissipation unit, characteristics not found in the metal itself with a coating film excelling in thermal conductivity and excelling in wettability with the refrigerant.A heat exchanger member made of metal having a surface that comes into contact with a refrigerant when a heat exchanger is operated includes a metal oxide film provided on the surface, having protrusions, and containing crystalline carbon. An average spacing between apexes of the protrusions is greater than or equal to 20 nm and less than or equal to 80 nm, an average value of the heights of the apexes of adjacent protrusions is greater than or equal to 10 nm and less than or equal to 70 nm, and an aspect ratio which is a value obtained by dividing the average height by the average spacing is less than one.
