Device for controlling heat dissipation of apparatus and apparatus having the same
Abstract:
A device for controlling heat dissipation of an apparatus and an apparatus having the same are provided. The apparatus comprises at least one heat radiation component. The device comprises: an ambient temperature sensing unit adapted to obtain an ambient temperature of internal space of the apparatus; a component temperature measuring unit adapted to obtain a local temperature for one of the at least one heat radiation component; and a temperature control unit adapted to select a corresponding temperature control profile based on the ambient temperature, and to obtain a control parameter for controlling the temperature of the apparatus based on the local temperature and the temperature control profile. According to the present invention, it is possible to select different temperature control profiles based on the ambient temperature, ant thus to satisfy both the requirement on system heat dissipation at high temperature and the requirement on noise at room temperature, and to avoid the noise resulted from large change in rotational speeds of fans due to change in the ambient temperature.
