PURPOSE: An evaporator is provided to improve productivity and improving an evaporating operation by reducing the thicknesses of films formed on the inner walls of evaporating tubes. CONSTITUTION: An evaporator includes a housing(1), a plurality of upper plates(7), a plurality of evaporating tubes(9), and a heating unit. An inlet introduces liquid to a storing space(S1) which is the upper part of an upper plate, and the liquid flows along the inner wall of the evaporating tubes to be evaporated. A tubular adapter is combined with the upper side of the evaporating tubes. The adapter includes a main body and a cover. The main body is composed of a tube combining part, a hooking part, and a liquid distributing part. The tube combining part is inserted into one evaporating tube. The hooking part limits the insertion of the tube combining part with respect to the evaporating tube. The liquid distributing part is divided from the tube combining part by the hooking part. One or more liquid inlets are perforated at the lateral side of the adapter cover. The lower part of the adapter cover is fixed to the hooking part to secure a cylindrical filling space.
