ABSTRACT:
A cooling device includes a refrigerant tank in which liquid refrigerant is boiled, and a radiator in which gas refrigerant is condensed. A connection pipe is formed in the radiator so that refrigerant communicates between the refrigerant tank and the radiator. An interior of the connection pipe is partitioned into a first communication passage and a second communication passage, and a restriction plate is provided between the first communication passage and a refrigerant-condensing passage of the radiator to prevent liquid refrigerant from flowing into the refrigerant-condensing passage. Thus, when heat-generating amount of a heat-generating member becomes larger so that liquid refrigerant is vehemently boiled in the refrigerant tank and a part of liquid refrigerant is blown upwardly together with refrigerant vapor, the restriction plate prevents the liquid refrigerant from flowing into the refrigerant-condensing passage of the radiator while gas refrigerant readily passes through the restriction plate.
