Abstract:
1. An electrical apparatus comprising: a casing comprising a first entrance, a first receptacle communicating with said first entrance, a first sidewall, and a first bottom surface, wherein at least one air inlet hole is formed in said first bottom surface, a concave region is defined at a junction between a central portion of said first sidewall and said first bottom surface, and at least one air outlet hole is formed in a second surface of said concave region, at least one air outlet hole is formed in a lateral surface of said concave region, said second surface is adjacent to said lateral surface and an angle is defined between said second surface and said lateral surface of said concave region, and at least one air outlet hole is formed in the two sides adjacent to said concave region of said first sidewall, said at least one air outlet hole of said second surface of said concave region is at a distance from said first sidewall; a control unit disposed on a first surface of said concave region, wherein said control unit is manipulated by a user to control operations of said electrical apparatus; a circuit board disposed within said first receptacle and having at least one electronic component mounted thereon; a top cover for sheltering said first entrance; and an active heat-dissipating element disposed within said first receptacle and arranged over said air inlet hole, wherein ambient air is inhaled into said first receptacle by said active heat-dissipating element and exhausted out of said casing through said air outlet holes of said second surface of said concave region, said lateral surface of said concave region and said first sidewall, thereby removing heat generated from said electronic component.
