NON-STOP TYPE COMPUTER

摘要

PURPOSE: To provide constitution capable of continuous operations without the need of stoppage even when abnormality is generated in a part of a cooling fan in a non-stop type computer for which logic system units for which at least one part is provided doubly and cooling system units provided in front and behind the respective logic system units are insertably and detachably arranged inside a case body. CONSTITUTION: Cooling air 48a from a take-in port 26a0 enters the case body 1 from an intake port 10a, passes through a CPU and DC/DC units 2a, 2b, 7a and 7b, enters cooling fan units 92a-92c and flows out from the take-out port of a top plate 14. The cooling air 48b from the take-in port 26b0 enters the case body 1 from the intake port 10b, passes through HDD units 3a and 3b and enters the cooling fan units 93a-93c. The part 48b1 passes through PS units 4a and 4b and flows out from the take-out port of a bottom plate 60, however, the other part 48b, flows into extension IO units 6a and 6b on a back surface side, joins the cooling air 48c from the take-in port 270 , becomes the cooling air 48d, passes through the cooling fan units 95a-95c and the IO units 5a and 5b and flows out from the take-out port of the top plate 14.
