Abstract
An electronic apparatus including a housing having an air outlet and a heat generating component in the housing, a heat sink in the housing and having heat radiating fins arrayed. The apparatus includes heat radiating fins having air flow paths between adjacent pairs of the heat radiating fins, and a fan in the housing. The fan feeds air to an air inlet of the heat sink to exhaust heat of the heat radiating fins from the air outlet of the housing. The air outlet of the housing has openings arrayed which divide the air flow paths formed between the pairs of heat radiating fins.
Claims9
An electronic device comprising:
- a housing including an air outlet;
- a heat generating component in the housing;
- a heat sink in the housing, the heat sink comprising:
- a heat radiating member, and
- a heat conducting member, the heat radiating member including a plurality of heat radiating fins arrayed, the plurality of heat radiating member fins having a plurality of air flow paths formed between adjacent pairs of the heat radiating fins, an air outlet which faces the air outlet of the housing and an air inlet which is in a side remote from the air outlet of the heat radiating fins, and the heat conducting member contacting the heat generating component to absorb heat and conducting the heat to the heat radiating member;
- and
- a fan in the housing, the fan feeding air to the air inlet of the heat radiating member to exhaust heat of the heat radiating fins from the air outlet of the housing;
- wherein the air outlet of the housing includes a plurality of openings arrayed and a part of the housing between each of the respective openings that divide the air flow paths formed between the pairs of heat radiating fins of the heat radiating member, as viewed in a direction looking from outside the housing to the air outlet of the housing.
