    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 cooling unit. 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： A heat receiver includes a casing defining a flow passage on a thermal conductive plate. The thermal conductive plate is received on an electronic component. The thermal conductive plate serves to transfer heat to coolant in the flow passage. At least two inflow nozzles extend into the casing to have discharge openings opposed to the upstream end of the flow passage. The coolant flows into the flow passage through the inflow nozzles. At least two streams of the coolant are thus generated in the flow passage. The streams widely expand or spread in the flow passage. The coolant flows through the flow passage without stagnating. The coolant can thus absorb the heat of the thermal conductive plate in an efficient manner. This results in an efficient heat absorption of the heat receiver.

    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.

    摘要： A heat exchanger allows establishment of first and second flat spaces, namely parallel flat spaces along a reference. The heat exchanger is inserted in a closed circulating loop for coolant. The first and second flat spaces have a cross-section larger than that of a cylindrical duct of the closed circulating loop. These flat spaces serve as a flow passage for the coolant. An increased cross-section enables a reduction in the flow speed of the coolant. The coolant is allowed to slowly flow through the first and second flat spaces. The coolant thus contacts with the first and second plates and the third and fourth plates for a longer time. The heat of the coolant is sufficiently transferred to the first and second plates and the third and fourth plates. The efficiency of heat radiation is enhanced.
