<p><P>PROBLEM TO BE SOLVED: To provide a plate-type heat exchanger capable of efficiently exchanging heat by securing circulation performance of a heat-exchanged medium without accumulating impurities even when the heat-exchanged medium including the impurities is circulated. <P>SOLUTION: In this plate-type heat exchanger which comprises a plurality of heat transfer plates having heat transfer portions on which a plurality of projections and recesses are alternately formed on both of front and rear faces, and in which the plurality of heat transfer plates are stacked in the state where the heat transfer portions are opposed to each other, and first spaces for circulating a heat exchange medium and second spaces for circulating the heat-exchanged medium are alternately formed at heat transfer portions as boundaries, the first space is formed between the heat transfer portions where the projections are crossongly butted, and the second space is formed between heat transfer portions where areas provided with the projections and recesses are kept in non-contact with each other. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
