Abstract
Tubes are provided substantially upright on an upper surface of a refrigerant container by inserting lower end portions thereof into inserting holes of the refrigerant container The tube A, differed from the tubes B, has a trumpet shape which is suddenly increased in its passage cross section towards the lower end opening portion. Thus, most of refrigerant vapor boiled and evaporated in the refrigerant container can be collectively introduced into the tube A located within the boiling area. The refrigerant vapor entered a header tank from the tube A is diffused in the header tank and is introduced into the tubes B located out of the boiling area. The condensate produced by cooling the refrigerant vapor upon passing through the tubes B can be circulated into the refrigerant container
