The method increases the heat transfer surface in the fluid flow characteristics of

摘要

The invention relates to a method for improving the liquid flow properties, such as its wettability and capillary flow, of a heat transfer surface prepared on a piece made of a metal, ceramic, polymeric or composite material or a combination thereof, or on a metal piece advantageously made of copper, a copper alloy, aluminum, an aluminum alloy or steel or a combination of these metals. The piece with a heat transfer surface is subjected to oxidation by heating the same under an oxygen-rich atmosphere or using at least one chemical oxidizer. The invention also relates to the use of a heat transfer surface prepared with the help of the method.
