<p>PROBLEM TO BE SOLVED: To provide an ebullient cooling apparatus, in which interference between refrigerant vapor and condensate in a heat radiation tube 9 is reduced, and refrigerant circulation power is ensured. SOLUTION: A radiation tube 9 is separated in an evaporation tube 9A and a condensation tube 9B. In the tube 9A, the insertion length L1 of the upper end inserted in a header 10 is set longer than a sheet thickness t1 of the header 10. In the tube 9B, the insertion length L2 of the upper end inserted in the header 10 is set equal to the thickness t1 of the header 10. Accordingly, the volume of condensate flowing from the header 10 through the tube 9A into the tube 9A becomes smaller, and the volume of condensate circulating through the tube 9B back to a refrigerant vessel is increased. As a result, a high volume of boiled and vaporized refrigerant flows into the tube 9A to circulate smoothly.</p> |
