PROBLEM TO BE SOLVED: To uniformly disperse an absorbing solution over an internal peripheral surface of an outer pipe in an absorption refrigerating machine. SOLUTION: An outer pipe 42 is coaxially provided on an outer periphery of part of a circulation pipe through which a heat medium is circulated, and a solution sprinkling pipe 49 is inserted into an evaporation absorption chamber 43, penetrating an upper end surface of the outer pipe. An annular solution reception pan 47 is provided along an internal peripheral surface of the outer pipe 42, and a plurality of sprinkling holes are provided in an equal interval along a boundary with the outer pipe 42. Just under the solution reception pan 47 a lath 60 is disposed over the outer pipe internal peripheral surface and is slantingly mounted such that each mesh of the lath is a line symmetrical with respect to a vertical line, and the number of meshes in a peripheral direction of the lath 60 is multiple times of the number of the sprinkling holes or the same number as those of the sprinkling holes. The absorbing solution flowing down from the sprinkling holes is uniformly distributed over the entire of the internal peripheral surface of the outer pipe 42 where the sprinkling holes and the lath 60 are properly disposed, and hence the absorbing solution is uniformly mixed and falls down for a long period of time, whereby the solution forms a uniform flow. Thus, an evaporated refrigerant is effectually absorbed through a circulation pipe wall, and hence cooling capability is effectually demonstrated.
