摘要： An electronic component generates heat in an electronic apparatus. The heat of the electronic component is transferred to a thermal conductive plate of a heat receiver in a liquid coolingunit. The heat is transferred to coolant from the thermal conductive plate. The temperature of the coolant rises. The heat exchanger absorbs heat of the coolant. The coolant gets cooled. The heat of the electronic component is also transferred to the printed wiring board. The heat spreads over the printed wiring board through a wiring pattern in the printed wiring board. Since the tank or/and pump is placed at a position outside the printed wiring board, the heat cannot be transferred to the tank or/and the pump. This results in prevention of rise in the temperature of the coolant in the tank or/and the pump. The efficiency of heat radiation can thus be enhanced.

摘要： An electronic apparatus includes an enclosure enclosing a liquid cooling unit. The liquid cooling unit includes a heat receiver received on an electronic component. Heat of the electronic component is transferred to the heat receiver. The heat of the heat receiver is transferred to the coolant flowing through the flow passage of the heat receiver. The electronic component gets cooled. The coolant flows into a tank in the liquid cooling unit. The tank stores the coolant and air. The air inlet is formed in the enclosure. Fresh air is introduced into the enclosure through the air inlet. Since the tank is opposed to the air inlet, the tank is exposed to the fresh air. The heat of the coolant in the tank is thus radiated into the air. The coolant gets cooled in an efficient manner. The efficiency of heat radiation is enhanced in this manner.
