<p><P>PROBLEM TO BE SOLVED: To provide a solution spraying structure of a multiplate type heat exchanger for uniformly spraying a solution, and improving heat exchange efficiency while restraining cost. <P>SOLUTION: In this multiplate type heat exchanger, elements 4 formed by mutually superposing two plate-like bodies 5 and 6 of applying recess-projection work to both surfaces, are superposed in a plurality between a pair of rectangular side plates 2 and 3, and an element inside space 7 inside of the respective elements 4 is formed as a passage for passing one of a heat transfer medium, and an element outside space 8 between the respective elements is formed as a passage for passing the other solution medium. Upper end recessed parts 4a are formed by upwardly extending both ends of an upper end horizontal part having a maximum width of the respective elements 4, and the upper end recessed parts 4a of the respective elements 4 are mutually watertightly joined, and an upper part of the rectangular side plates 2 and 3 and the upper end recessed parts 4a of the outermost side both elements 4 are watertightly joined. An upward opening solution medium storage tank 12 is formed of the respective upper end recessed parts 4a and the upper part of a pair of side plates 2 and 3, and communicating holes 13 and 14 for communicating with the element outside space 8 from the storage tank 12 are arranged in a plurality of rows in the plate-like bodies 5 and 6 for forming the upper end recessed parts 4a. <P>COPYRIGHT: (C)2004,JPO</p> |
