PURPOSE:To cool components in a cubicle uniformly by communicating the interior of the cubicle with the outer air through a cross duct of suction and discharge ducts disposed at an end of a horizontal partition board and through vents made at the upper and lower parts of the cubicle. CONSTITUTION:A partition board 4 is provided horizontally in the housing 1 of a cubicle and heating elements 3b, 3a are disposed, respectively, in the upper and lower spaces 12, 11. A cross duct 5 alternately formed with upwardly inclining faces 6a and downwardly inclining faces 7a is disposed at a part where the partition board 4 contacts with a door 2 so that discharge ducts 6 and suction ducts 7 open alternately between upper and lower doors 2, 2' thus communicating the interior of the cubicle with the outer air. Furthermore, vents 2b, 2a are made at upper and lower parts of the front and rear faces of the housing 1. Air is fed through the vent 2a to cool the heating element 3a and discharged through the discharge duct 6. Similarly, air is fed through the suction duct 7 to cool the heating element 3b and discharged through the vent 2b. Consequently, heating components in the housing are cooled uniformly. |
