Fluid circulation device

Abstract

Provided is a fluid circulation device capable of preventing that efficiency of a treatment by a fluid circulation is significantly lowered, even in a case where a blockage has occurred in a micro-channel, to prevent lowering of an operating rate. The fluid circulation device 1 is provided with a structure body 2 comprising: a plural number of second flow passages 22 extended in a direction, and at the same time, arranged so as to be lined up in a direction intersecting the direction, each for circulating a second fluid; and introduction part-communicating parts 75 , first to third communicating parts 78, 79 and 80 for linking second flow passages 22 adjacent to each other in the arrangement direction of the plural number of second flow passages 22 to allow communicating with each other; formed therein.

What is claimed is: 
     
         1 . A fluid circulation device for circulating a fluid comprising a structure body which comprises:
 a plural number of micro-channels extended in a direction, and at the same time, arranged so as to be lined up in a direction intersecting the direction, each for circulating the fluid; and   at least one communicating part for linking micro-channels adjacent to each other in an arrangement direction of the plural number of micro-channels to each other, to allow communicating with each other; formed inside of the structure body.   
     
     
         2 . The fluid circulation device according to  claim 1 , wherein:
 the plural number of micro-channels comprises a plural number of first micro-channels extended in a direction, and at the same time, arranged so as to be lined up in a direction intersecting the direction in the structure body, each for circulating the first fluid, and a plural number of second micro-channels disposed in a parallel direction vertical both to the extended direction of the first fluid passages and the arrangement direction of the first fluid passages in the structure body, with being spaced from the row of the plural number of first micro-channels, and at the same time, arranged in parallel with the row of the first micro-channels, each for circulating the second fluid;   the structure body comprises an arrangement area with the plural number of first micro-channels arranged therein, and a non-arrangement area positioned outside the arrangement area, with no first micro-channel arranged therein, when the structure body is viewed from the parallel direction; and   the at least one communicating part comprises a non-arrangement area-communicating part which is provided to the non-arrangement area, allowing second micro-channels adjacent to each other to communicate with each other.   
     
     
         3 . The fluid circulation device according to  claim 2 , wherein:
 each of the second micro-channels comprises an introduction part which is a part disposed in the non-arrangement area, and is a part extended over a predetermined area in a side downstream from an inlet of the second micro-channel; and   the non-arrangement area-communicating part allows the introduction parts of the second micro-channels adjacent to each other to communicate with each other.   
     
     
         4 . The fluid circulation device according to  claim 1 , wherein:
 each of the micro-channels comprises a curving part and a downstream part which follows the curving part downstream; and   the at least one communicating part comprises a downstream part-communicating part for allowing the downstream parts of the micro-channels adjacent to each other to communicate with each other.   
     
     
         5 . The fluid circulation device according to  claim 1 , wherein:
 the plural number of micro-channels comprises a plural number of first micro-channels extended in a direction, and at the same time, arranged so as to be lined up in a direction intersecting the direction in the structure body, each for circulating the first fluid, and a plural number of second micro-channels disposed in a parallel direction vertical both to the extended direction of the first fluid passages and the arrangement direction of the first fluid passages in the structure body, with being spaced from the row of the plural number of first micro-channels, and at the same time, arranged in parallel with the row of the first micro-channels, each for circulating the second fluid;   the structure body comprises an arrangement area with the plural number of first micro-channels arranged therein, and a non-arrangement area positioned outside the arrangement area, with no first micro-channel arranged therein, when the structure body is viewed from the parallel direction;   the at least one communicating part comprises a plural number of arrangement area-communicating parts which are provided to the arrangement area, allowing parts of adjacent second micro-channels disposed in the arrangement area to communicate with each other;   the plural number of arrangement area-communicating parts are lined up in a direction intersecting the first flow passage which overlaps with the arrangement area-communicating parts, when the structure body is viewed from the parallel direction.   
     
     
         6 . The fluid circulation device according to  claim 1 , wherein the communicating part has a width equal to or less than a flow passage width of the micro-channel. 
     
     
         7 . The fluid circulation device according to  claim 2 , wherein:
 each of the micro-channels comprises a curving part and a downstream part which follows the curving part downstream; and   the at least one communicating part comprises a downstream part-communicating part for allowing the downstream parts of the micro-channels adjacent to each other to communicate with each other.   
     
     
         8 . The fluid circulation device according to  claim 3 , wherein:
 each of the micro-channels comprises a curving part and a downstream part which follows the curving part downstream; and   the at least one communicating part comprises a downstream part-communicating part for allowing the downstream parts of the micro-channels adjacent to each other to communicate with each other.
