Abstract:
A boiling cooler for cooling a heating element, the boiling cooler comprising:a refrigerant vessel storing liquid refrigerant therein, the refrigerant vessel having a boiling portion where the liquid refrigerant boils to produce refrigerant vapor, and defining therein a vapor outflow passage through which the refrigerant vapor flows toward first and second outlet portions provided at opposite ends of the vapor outflow passage; a first radiator disposed at a first end side of the refrigerant vessel to communicate with the first outlet portion of the vapor outflow passage; and a second radiator disposed at a second end side of the refrigerant vessel, opposite to the first side, to communicate with the second outlet portion of the vapor outflow passage, wherein; each of the first and second radiators includes a heat exchange part having a vapor passage in which the refrigerant vapor from the vapor outflow passage flows to perform heat exchange with liquid coolant, and a tank defining a refrigerant chamber that communicates with the refrigerant vessel and stores therein the liquid refrigerant with a liquid surface; the vapor passage of the heat exchange part is provided above the liquid surface stored in the tank; and the vapor outflow passage is provided in the refrigerant vessel to extend in a direction crossing with a vertical direction.
