Claims17
A cooling auxiliary unit used for an accommodation room configured to accommodate one or more electronic apparatuses, said cooling auxiliary unit comprising:
- a duct member that stands upon a ventilation hole provided in a raised floor, and has an air passage connected to the ventilation hole, and at least one opening connected to the air passage;
- and
- a fan that moves air along the air passage,
- wherein the duct member includes:
- a top plate configured to shield the air passage;
- a first duct part that includes a first exhaust surface facing a predetermined direction parallel to the raised floor and intersecting a central axis of the duct member perpendicular to the raised floor, the first duct part having a first width, and the first exhaust surface having at least one of the openings;
- and
- a second duct part that is provided between the first duct part and the top plate and includes a second exhaust surface having at least another of the openings in the predetermined direction, a width of the second duct part gradually increasing in a direction from the first duct part to the top plate,
- wherein 2.1Px≦Dc≦13Px is met where Px is the first width, and Dc is a second width of the top plate.
A method of cooling a pair of electronic apparatuses using air exhausted from openings in a duct member that stands upon a ventilation hole provided in a raised floor and is provided between the pair of electronic apparatuses, the duct member having an air passage connected to the ventilation hole, and the openings being connected to the air passage,
- wherein the duct member includes:
- a top plate configured to shield the air passage;
- a first duct part that includes a first exhaust surface facing a predetermined direction parallel to the raised floor and intersecting a central axis of the duct member perpendicular to the raised floor, the first duct part having a first width, and the first exhaust surface having at least one of the openings;
- and
- a second duct part that is provided between the first duct part and the top plate and includes a second exhaust surface having at least another of the openings in the predetermined direction, a width of the second duct part gradually increasing in a direction from the first duct part to the top plate,
- wherein 2.1Px≦Dc≦13Px is met where Px is the first width, and Dc is a second width of the top plate, and
- the method comprising the step of arranging the pair of electronic apparatuses so that 0.7D≦Dc≦1.3D is met where D is a distance between the pair of electronic apparatuses.
