Abstract
A heat radiation device for a thin electronic apparatus includes a rectangular plate-shaped base, a rectangular intermediate plate stacked on the base, a rectangular box-shaped cover stacked on the intermediate plate, and a fan. A depression is formed at a center portion of the base. A plurality of parallel fins are provided to form a discharge port for cooling air. The depression and the discharge port are connected via an arcuate communication portion. A circular opening is formed in the intermediate plate at a position corresponding to that of the depression, and the fan is attached to the circular opening. The intermediate plate and the base are connected together such that heat can be conduced therebetween. When the end surface of a side plate provided at each longer side of the cover is caused to abut the intermediate plate and/or the base, an intake port for cooling air is formed at a shorter side of the cover. When the fan is operated, cooling air is caused to flow between the intake port and the discharge port, so that heat accumulated within the base is radiated to the outside.
