Patent ID: 7701715

Claim:
An electronic apparatus comprising: an enclosure having an air inlet and an air outlet; a printed wiring board enclosed in the enclosure and located between the air inlet and the air outlet; an electronic component enclosed in the enclosure, the electronic component being mounted on the printed wiring board; a closed circulating loop for coolant; a heat receiver enclosed in the enclosure, the heat receiver having a thermal conductive plate received on the electronic component, the heat receiver being inserted in the closed circulating loop so as to define a flow passage on the thermal conductive plate; a heat exchanger enclosed in the enclosure, the heat exchanger being inserted in the closed circulating loop to radiate heat of the coolant into air; a tank enclosed in the enclosure and located between the air inlet and the printed wiring board, the tank being inserted in the closed circulating loop so as to store the coolant and air in the closed circulating loop; and a fan enclosed in the enclosure, to generate an airflow in the enclosure from the air inlet to the air outlet, the airflow flowing from the air inlet to the tank, the printed wiring board, the fan, the heat exchanger, and then the air outlet.
