HEAT EXCHANGER AND PRODUCTION METHOD FOR HEAT EXCHANGER
First Claim
1. :
- A heat exchanger that allows at least a first fluid and a second fluid to exchange heat therebetween while allowing those fluids to circulate,the heat exchanger comprising a stacking block having therein a first flow path that allows the first fluid to circulate and a second flow path that allows the second fluid to circulate,wherein the stacking block has;
a first plate surface being a plate surface on one side;
a second plate surface being a plate surface on the opposite side to the first plate surface;
a first flow path plate formed with a plurality of first through holes having a constant shape;
a second flow path plate formed with a plurality of second through holes having the same constant shape as the first through holes;
a first seal plate stacked on the second plate surface; and
a second seal plate stacked on a plate surface of the second flow path plate on the opposite side to the first flow path plate,wherein in the first flow path plate, the first through holes are arranged so as to line up in a constant arrangement pattern in a first direction in which the first flow path allows the first fluid to flow,wherein in the second flow path plate, the second through holes are arranged so as to line up in the first direction in the same constant arrangement pattern as the first through holes, andwherein each of the first through holes has regions overlapping with the second through holes located on both sides of the first through hole in the first direction, and the first flow path is formed by the first through holes and the second through holes being alternately connected in the first direction in the regions where those through holes overlap.

Abstract
A heat exchanger including a stacking block, including: a first plate surface; a second plate surface opposite to the first plate surface; and first and second flow path plates including respective plural first and second through holes that have a standard shape. The first through holes are arranged to line up in a standard array pattern in a first direction in which a first flow path causes a first fluid to flow. The second through holes are arranged in the first direction in the same standard array pattern as the first through holes. Each of the first through holes have an area with a same overlap with the second through holes positioned on both sides of the first through holes, in the first direction. The first flow path is formed by the first and second through holes being mutually joined in the first direction, in the areas of overlap.

14. :
- A method for producing a heat exchanger that allows at least a first fluid and a second fluid to exchange heat therebetween while allowing those fluids to circulate, the method being provided with a stacking block forming step for forming a stacking block having therein a first flow path that allows the first fluid to circulate and a second flow path that allows the second fluid to circulate,
wherein the stacking block forming step includes a first flow path forming step for forming the first flow path in the stacking block, and a second flow path forming step for forming the second flow path in the stacking block, wherein the first flow path forming step has;
a first through hole forming step for forming a plurality of first through holes having a constant shape in a first flow path plate so as to line up in a constant arrangement pattern in a first direction in which the first flow path allows the first fluid to flow;
a second through hole forming step for forming a plurality of second through holes having the same constant shape as the first through holes in a second flow path plate so as to line up in the same constant arrangement pattern as the arrangement pattern of the first through holes; and
a first stacking step for stacking the second flow path plate to the first flow path plate, and for stacking a first seal plate to a plate surface of the first flow path plate on the opposite side to the second flow path plate so as to seal the openings of the plurality of first through holes formed in the plate surface, and stacking a second seal plate to a plate surface of the second flow path plate on the opposite side to the first flow path plate so as to seal the openings of the plurality of second through holes formed in the plate surface, andwherein in the first stacking step, the second flow path plate is stacked to the first flow path plate so that each of the first through holes partially overlaps with the second through holes located on both sides of the first through holes in the first direction, and the first flow path is formed by the first through holes and the second through holes being alternately connected in the first direction in the regions where those through holes overlap. - View Dependent Claims (15, 16, 17)
