Patent ID: 7495911

Claim:
An active heat-dissipating type of power supply apparatus comprising: a casing including a first side with at least one first airflow opening; a first airflow channel and a second airflow channel defined within said casing, said second airflow channel using said first airflow opening as one of an inlet and an outlet; plural electronic components mounted within said casing and disposed in said first airflow channel; an airflow driving device disposed on said first side of said casing and including an airflow gate; a power input device disposed on said first side of said casing and in said second airflow channel; and a heat-insulating plate disposed between said electronic components and said power input device, wherein a gap is formed between a sidewall of said airflow driving device and said heat-insulating plate, and said second airflow channel is communicated with said first airflow channel through said gap; wherein a cooling air is pumped by said airflow driving device to be introduced into said second airflow channel through one of said first airflow opening and said airflow gate, so that the heat generated from said power input device is removed by said cooling air and exhausted through the other one of said first airflow opening and said airflow gate.
