Title:
HEAT EXCHANGER MEMBER, HEAT EXCHANGER, AND COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/187088
Kind Code:
A1
Abstract:
In the present invention, a highly efficient heat exchanger member, a heat exchanger, and a cooling system are realized by coating the surface of a metal, which is in contact with a refrigerant of the heat exchanger used in a cooling unit or a heat dissipation unit, with a film that has excellent thermal conductivity and superior wettability with the refrigerant, thereby conferring properties that the metal itself does not have. The heat exchanger member, which comprises a metal with a surface that is in contact with the refrigerant when the heat exchanger is operating, has a metal oxide film that provides protrusions to said surface and that contains crystalline carbon. The average interval of the vertices of the protrusions is 20-80 nm; the average value of the height of the vertices of adjacent protrusions is 10-70 nm; and the aspect ratio, which is a value obtained by dividing the average height by the average interval, is less than 1.
