Electronic apparatus

An electronic apparatus comprising:

• a housing including a sealable housing section;
• a plurality of heat generating components accommodated within the housing section;
• an internal-side heat exchange section disposed in contact with one inner surface of one wall of the housing configuring the housing section, the one inner surface facing the housing section;
• an external-side heat exchange section including:
• a first external-side heat exchange section portion disposed in contact with one outer surface of the one wall in an opposed relationship with the internal-side heat exchange section, the one outer surface facing an outside of the housing section;
• and
• a second external-side heat exchange section portion for heat exchange between the heat generating components and external air outside the housing section;
• and
• an internal fan accommodated within the housing section, wherein
• the heat generating components include a high-heat generating component disposed in contact with the one inner surface in an opposed relationship with the second external-side heat exchange section portion, the high-heat generating component generating a largest amount of heat among the heat generating components during an operation,
• the internal fan circulates internal air in the housing section to deliver the internal air to the internal-side heat exchange section,
• heat exchange between the high-heat generating component and the external air outside the housing section is effected through the second external-side heat exchange section portion, and
• heat exchange between the internal air inside the housing section and the external air outside the housing section is effected through the internal-side heat exchange section and the first external-side heat exchange section portion.
