Multi-flow passage device

Abstract

A multi-flow passage device capable of surely performing a desired treatment, such as heat exchange or chemical reaction, even to large amounts of medium is provided. A multi-flow passage device 1 according to the present invention is constituted by stacking units for performing heat exchange or chemical reaction of the introduced medium in a thickness direction, and a flow passage 9 for allowing the flowing medium in one unit 7 to flow in another unit 7 adjacent to the unit 7 is an external flow passage 8 provided outside of one unit 7 and another unit 7.

1 . A multi-flow passage device constituted by stacking units for performing heat exchange or chemical reaction of the introduced medium in a thickness direction,
 wherein a flow passage for allowing the flowing medium in one unit to flow in another unit adjacent to the unit is an external flow passage provided outside of one unit and another unit.   
     
     
         2 . The multi-flow passage device according to  claim 1 , wherein the external flow passage is provided in contact with the side surface of the unit. 
     
     
         3 . The multi-flow passage device according to  claim 1 , wherein inside the external flow passage, a redistribution means for mixing the medium flowing out of one unit and allowing the medium to be redistributed to another unit is provided. 
     
     
         4 . The multi-flow passage device according to  claim 3 , wherein the redistribution means comprises a porous plate which is disposed inside the external flow passage so as to intersect with the medium flowing direction and through which the medium is allowed to pass. 
     
     
         5 . The multi-flow passage device according to  claim 2 , wherein inside the external flow passage, a redistribution means for mixing the medium flowing out of one unit and allowing the medium to be redistributed to another unit is provided.
