PURPOSE:To make a uniform cooling of all electronic devices by a method wherein cooling air is flowed from an air supplying chamber and right triangular openings at both rising ducts along a guiding inclined wall through a bottom surface of fixing panel to cool the electronic devices and discharged to the rear surface of the device. CONSTITUTION:A rising duct 5 is arranged at a side surface 5-1 in each of the stages where a substantial right angular opening 7 is made in an electronic device 1. The upper surface of the opening 7 is a fixing panel 3-1, and an opening 3-2 is arranged near the electronic device 1. A rear surface of the electronic device 1 is prodided with an opening. The cooling air is fed, as indicated by an arrow, from a feeding-out port 15 of an air conditioner 14 to the air supplying chamber 9 below the lifting floor 4, enters from the air inlet opening 10 into the rising duct 5, and fed from the blowing port 7 for the electronic device arranged at each of the stages at both racks of the rising duct 5 by a separator 6. The cooling air cools the electronic device at each of the stages, is discharged into the room from each of the stages at the rear surface of the rack, merged and mixed with the cooling air blown from the blowing port 8 at the upper and rear surface of the rising duct 5 and then is returned from the suction port 13 back to the air conditioner 14. |
