摘要
A channel forming body for mounting semiconductor power modules or a heat sink for power modules has a heat-transfer portion having a very complicated construction in order to increase the heat-transfer coefficient, leading to need for extremely high techniques and high cost for manufacturing.;By arranging an expanded metal 13 in a channel 12 formed to lie between two planes 11 and 11 placed face-to-face, local fluid flows 16 guided by the expanded metal 13 are allowed to act on various boundary layers 15 formed between these two planes 11 and 11 and a fluid so as to improve fluid flow characteristics concerning heat transfer and/or mass transfer through a local turbulent flow acceleration effect.
