PROBLEM TO BE SOLVED: To provide a boiling cooling device in which the heat radiating area of a condensing section can be made larger as compared with the whole physical constitution of the device and which can be assembled easily. SOLUTION: In a boiling cooling device, a coolant tank 3 and bursting tubes 4 are respectively formed of extruded sections and arranged in nearly parallel with each other in the same direction. The tubes 4 constitute a condensing section together with heat radiating fins 5 and the tubes 4 and fins 5 are alternately piled upon another in a plurality of stages. Headers 6 are composed of a header 6A to which one opened end sections of the tank 3 and tubes 4 are assembled and another header 6B to which the other opened end sections 3 of the tank 3 and tubes 4 are assembled. Each header 6 is formed in a flat hollow shape by only joining the peripheries of two plate members 6 press- worked in rectangular shapes to each other and one plate member 6b has openings into which the opened end sections of the tank 3 and tubes 4 are inserted. |
