Abstract:
1. An electronic device comprising: a casing interiorly accommodating electronic components including a heat-emitting component that emits heat during operation, the casing having an exteriorly opening discharge outlet; a heat-dissipating unit including: a first shutter provided on a side of the heat-dissipating component that is reverse from the opposing side of the heat dissipating component, and facing the discharge outlet in the casing that opposes the fan, wherein when the heat-dissipating unit is in a first mode of operation, the first shutter configured for allowing airflow through the heat-dissipating component and the discharge outlet, whereby heat transferred from the heat-emitting component to the heat-dissipating component is heat-exchanged with the air flowing from the fan, the heated airflow being released outside the casing through the discharge outlet, and wherein when the heat-dissipating unit is in a second mode of operation, the first shutter configured for shutting off the airflow through the heat-dissipating component and the discharge outlet, whereby the air from the fan main unit flows along the opposing side of the heat-dissipating component and passes through the opening formed in the fan case.
