Patent ID: 8867208

Claim:
An electronic device comprising: a casing in which electronic components including a heat-emitting component, which emits heat during operation, are accommodated; and a heat-dissipating unit that includes a heat-dissipating component having a plurality of fins to which heat is transferred from the heat-emitting component, and a fan for supplying air to the heat-dissipating component, wherein heat exchange between heat transferred from the heat-emitting component to the heat-dissipating component, and air supplied from the fan, is performed to release heated air to the exterior of the casing; wherein a communicating path is formed, between an air outlet of the fan, and a surface of the heat-dissipating component on a side that opposes the fan, for communicating therebetween; a dust removal path is formed connected to the communicating path so as to communicate with the exterior of the casing; and the dust removal path is formed so as to be tilted at an angle less than or equal to 90° relative to a direction opposite to a flow direction of air supplied from the fan.
