Ventilation system for casing containing electronic components, includes grille sections formed by arrays offset along air entry path into casing

摘要

Sections forming the grille are arranged in two or more arrays (9a, 9b), which are offset along the air (or gas) entry path through the grille and into the casing (30). Numbers of such grilles are similarly offset along the entry path. Independent claims are included for the mold used for manufacture, and the casing and its ventilated sections.
