ELECTRONIC APPARATUS DEVICE

PROBLEM TO BE SOLVED: To provide an electronic apparatus device where an optimum amount of circulating air is divided into each electronic apparatus unit, in accordance with the quantity of heat generated in the unit. SOLUTION: By providing partition walls 7, 8 in an enclosed box 1, its inside is divided into ventilating ducts 9, 10, 11 which form independent individual inside air circulating paths A1 , A2 , A3 , so that a required amount of circulating air from an inside air circulating fan 5 may flow into each electronic apparatus unit 31, 32, 33 from a heat exchanger 4, and the amount of heat generated in the unit. Consequently, it is possible to balance and uniformize the temperature rises of the electronic apparatus units 31, 32, 33. Along with it, it is possible to reduce the dimensions of the electronic apparatus device, and to make the density of the electronic apparatus units higher in addition.
