8. A method of cooling an electronic apparatus, the apparatus including a housing that forms a sealed inner space and including a circuit unit provided in the inner space, the method comprising:
causing a full circulation of air flow in the inner space from a portion of the inner space through the inner space and returned back to the portion of the inner space by; feeding the air in the inner space from a side of a lower surface of an upper/lower partition portion to a side of an upper surface of the upper/lower partition portion through an opening provided on the upper/lower partition portion, the upper/lower partition portion being provided in the inner space and extending horizontally in the inner space such that at least a part of the circuit unit is separated from an upper space of the upper/lower partition portion; guiding the air along the upper surface of the upper/lower partition portion toward side surfaces of the housing, the air being fed to the side of the upper surface of the upper/lower partition portion; cooling the air while guiding the air in a downward direction along the side surfaces of the housing, the air reaching the side surfaces of the housing; and guiding the cooled air in an upward direction toward the opening.
