Menetelmä jäähdytyselementin valmistamiseksi ja menetelmällä valmistettu jäähdytyselementti

摘要

The invention relates to a method of fabricating a pyrometallurgical reactor cooling element with flow channels. In order to enhance heat transfer capability, the wall surface area of the flow channel, which is traditionally round in cross-section, is increased without increasing the diameter or length of the channel.
