A closed forced air system cools the electronic circuitry in a control
console of an x-ray inspection station directed to food products in
containers. A U-shaped tubular duct located beneath the console enclosure
has both upwardly-directed ends attached to the bottom panel of the
enclosure with openings provided for airflow communication, thus creating
a closed loop air passageway. A pair of electric fans are installed at
the upper ends of the U-shaped duct in manner to circulate air flow
through the loop. Air in the enclosure, warmed by the electronic control
circuitry, is drawn by one fan down into one arm of the U. The duct acts
as a heat dissipater, and cool air at the opposite arm of the U is drawn
by the other fan back up into the enclosure. The bottom of the U-shaped
duct is attached to a front region of a support platform at the floor
level and thus the arms of the U serve as a front pair of supports. A
straight tubular support strut, extending from the enclosure down to a
rear portion of the platform as a rear support, may serve as a wiring
conduit.
