<p>PROBLEM TO BE SOLVED: To provide an ebullient cooling device which is simple in structure and can circulate refrigerant at a low cost. SOLUTION: In the device 1, a radiator 4, which has a plurality of refrigerant condensing pipes 9 and radiating fins 10, is located on 1 both sides of a refrigerant bath 3. The refrigerant condensing pipes 9 are bent into U-shapes, both open ends 9a and 9b of which are inserted into round holes made in a wall of a bath body 5 to be opened to a communication chamber 8 and are integrally connected thereto, together with the refrigerant bath 3 by brazing. With respect to the refrigerant condensing pipes 9, however, a positional relationship between one open end 9a and the other open end 9b is the vertical one relative to the refrigerant bath 3, and one open end 9a positioned at an upper position has an open cross section area (pipe diameter) than the other open end 9b positioned at a lower position.</p> |
