Abstract:
A cooling apparatus including a heat generating element arranged in a housing, comprising:a sole cooling fan arranged in an interior of said housing and providing an air flow to the heat generating element, said sole cooling fan being the only cooling fan in said housing; intake hole portions formed in said housing for allowing an air flow to be supplied from an outside of the housing to the air flow produced by said sole cooling fan; and exhaust hole portions formed in said housing for allowing the air flow provided to the heat generating element by said sole cooling fan to be discharged to the outside of the housing, wherein a first path length of a first path for the air flow from said intake hole portions to said sole cooling fan is substantially equal to a second path length of a second path for the air flow from said sole cooling fan to said exhaust hole portions, wherein said intake hole portions include first and second intake holes and said second intake hole is provided in a position below said first intake hole, so that air heated by the heat generated by the heat generating element flows upwardly from a bottom of the housing.
