Abstract:
A cooling device for boiling and condensing refrigerant, the cooling device cooling a heat-generating member contained within a housing, comprising:a first heat exchanger in which refrigerant flows, said first heat exchanger being disposed inside said housing to perform heat exchange between said refrigerant flowing therethrough and high-temperature first fluid within said housing; a second heat exchanger in which refrigerant flows, said second heat exchanger having upper and lower tanks extending in a tank longitudinal direction and a plurality of tubes through which said upper and lower tanks communicate with each other, said second heat exchanger being disposed outside said housing to perform heat exchange between said refrigerant flowing therethrough and low-temperature second fluid outside said housing; a first connection pipe through which gas refrigerant boiled in said first heat exchanger is introduced into said upper tank of said second heat exchanger; and a second connection pipe through which liquid refrigerant condensed in said second heat exchanger is returned to said first heat exchanger from said lower tank of said second heat exchanger, wherein: said first connection pipe has a plurality of first branched pipes connected to said upper tank of said second heat exchanger in a T-shape; and said second connection pipe is connected to said lower tank of said second heat exchanger in such a manner that position relationships of said first branched pipes relative to said second connection pipe are left-right unsymmetrical.
