Abstract

PURPOSE:To excellently cool a semiconductor component placed in a package in the uppermost stage unit of a book shelf unit stacked in multiple stages by providing a discharge duct at the top of the unit disposed at the uppermost stage. CONSTITUTION:In an electronic device 1 in which a plurality of units 4 having packages 3 for placing semiconductor components in multiple stages in a book shelf type are stacked in multiple stages through convection guide plates 5 in a cabinet 2 to be cooled by a natural air cooling type, a discharge duct 7 is provided at the top of the unit 4 disposed at the uppermost stage. Or, a front face cover 8 for shielding the flow of air to be intaken is further attached to the top of the front face of the unit of the upper most stage. Thus, since a chimney effect of the duct 7 can be utilized, discharging efficiency is raised, and more air 6 can be accordingly intaken from the front face of the unit 4. As a result, the environmental temperature of the component placed on the package 3 of the unit 4 disposed at the uppermost stage can be reduced.
