ABSTRACT:
An electronic equipment has a cooling structure in which air discharged from heat sinks can be recovered without any leakage and compact blow ducts and discharge ducts are disposed in a narrow space. A supply opening and a discharge opening for cooling air are independently formed in a heat sink. A plurality of supply branched ducts and discharge branched ducts are combined in a comb-like shape along the axis of the ducts. Ejection openings for cooling air are formed on each of the supply branched ducts in positions corresponding to each of the heat sinks. Such ejection openings are closely connected to the supply openings for cooling air of the heat sinks. On the other hand, recovery openings for cooling air are formed on each of the refrigerant discharge ducts in a position corresponding to each of the heat sinks. Such recovery openings are closely connected to the discharge openings for gas refrigerant of the heat sinks.
