ABSTRACT:
An electronic circuit assembly (10) including circuit boards (14, 16 and 18) includes a plenum (22) disposed adjacent the components (38 and 40) on the circuit boards for directing air from a blower (18) selectively onto the components (38 and 40). Struts (34, 34', and 82) extending between the plenum's face walls (24, 26) prevent excessive bowing of those walls under the pressure caused by the blower (18). As a consequence, the plenum can be made of material that is relatively thin and light.
