1. An electronic apparatus comprising:
- a housing comprising a printed circuit board which comprises a first surface comprising a first heat-generating component and a second surface that is opposed to the first surface;
a fan unit which comprises a case and a fan that is rotatably contained in the case, the case comprising an air intake part and an exhaust part configured to exhaust air directly on the first surface along the printed circuit board; and
first partition members which define a first ventilation space between the first surface and an internal surface of the housing, the first partition members configured to guide the air through the first ventilation space toward the first heat-generating component, whereinthe second surface comprises a second heat-generating component;
the exhaust part is configured to exhaust air directly on the second surface along the printed circuit board; and
the electronic apparatus further comprises a fifth partition member which defines a second ventilation space between the second surface and the internal surface of the housing the fifth partition member configured to guide the air through the second ventilation space toward the second heat-generating component.
