Abstract: A heat dissipating device includes an air flow tube having a mounting hole between an air inlet and an air outlet, a heat-conducting member mounted in the mounting hole in the air flow tube and adapted to be disposed in close proximity with a heat-generating component, and a fan unit mounted in the air outlet of the air flow tube and operable so as to draw air into the air flow tube via the air inlet for cooling the heat-conducting member in the mounting hole and to expel air in the air flow tube via the air outlet.

Abstract: The system is combined with an inlet and an outlet air vent. Within the inlet air vent, there is a cooling fan attached. Also there is a half-circled shape net piece designed in the air ventilation system that has numerous holes on the net piece. By using the half-circled shape net piece, it will create a greater contact of hot and cold air with the central processing unit. The cooling fan will create the air circulation passing through the central processing unit.
