Electronic apparatus having heat sink for cooling heat generating component

摘要

The electronic apparatus comprises a housing including a heat generating component and a heat sink. The housing can be displaced between a first usage form in which a ventilation port is set maintained in a standard opening shape and a second usage form in which the ventilation port is expanded to be larger than the standard opening shape. The heat sink has a plurality of heat radiation fins. The heat radiation range of the heat radiation fins expands when the housing is displaced from the first usage form to the second usage form and is reduced when the housing is displaced from the second usage form to the first usage form.
