Summary: | PROBLEM TO BE SOLVED: To provide a flooded-double tube evaporator capable of suppressing the rise of moisture density in refrigerant solution by efficiently taking out the refrigerant solution with a high moisture density from the inside of a refrigerant liquid chamber 16 while preventing a convection mixing on the axial inside front and rear sides of the tubular refrigerant liquid chamber 16. SOLUTION: The refrigerant liquid in refrigerant vapor evaporated from the refrigerant solution in the refrigerant liquid chamber 6 is releasably collected in a vapor-liquid separator 21 and returned to the inside of the refrigerant liquid chamber 16 through a refrigerant liquid feed pipe 18. A refrigerant solution feed port 19 is provided at the axial one end part of the outer tube 14, and a refrigerant vapor outlet 24 for discharging the refrigerant vapor and a refrigerant solution outlet 20 for taking out the refrigerant solution are provided the end part of the vapor-liquid separator 21 on the same side as the axial other end of the outer tube. The refrigerant solution and refrigerant vapor are allowed to flow in the refrigerant liquid chamber 16 and the vapor-liquid separator 21 along the axial direction of the tube. A partition body 15 for axially partitioning at least an upper side portion in the refrigerant liquid chamber 16 into front and rear parts and a dam-like member 26 for axially partitioning the bottom side portion of the vapor-liquid separator 21 into front and rear parts are installed.
