Abstract

In a channel structure of a channel device, first confluence channels of a plurality of first channels include a plurality of first confluence channels arranged along a second board front surface, first confluence portions of the first channels in each of first boards are configured of a plurality of first confluence portion through-holes that penetrate the first board, and second first-liquid introduction channel and second second-liquid introduction channels of a plurality of second channels are arranged along the second board front surface and are located in an area that is deviated from the first confluence channels in a view in a direction along a stacking direction of the first board and the second board.

First claim

1 . A channel device comprising:
a channel structure having therein a plurality of first channels and a plurality of second channels, the plurality of the first channels and the plurality of the second channels allowing a first liquid and a second liquid to join and flow through the first and second channels, respectively, wherein each of the plurality of the first channels includes: a first first-liquid introduction channel into which the first liquid is introduced; a first second-liquid introduction channel into which the second liquid is introduced; a first confluence portion connected to both a downstream end of the first first-liquid introduction channel and a downstream end of the first second-liquid introduction channel to cause the first liquid flowing through the first first-liquid introduction channel and the second liquid flowing through the first second-liquid introduction channel to join together; and a first confluence channel connected to the first confluence portion on a downstream side of the first confluence portion to allow a liquid mixture of the first liquid and the second liquid having joined at the first confluence portion to flow through the first confluence channel, each of the plurality of the second channels includes: a second first-liquid introduction channel into which the first liquid is introduced; a second second-liquid introduction channel into which the second liquid is introduced; a second confluence portion connected to both a downstream end of the second first-liquid introduction channel and a downstream end of the second second-liquid introduction channel to cause the first liquid flowing through the second first-liquid introduction channel and the second liquid flowing through the second second-liquid introduction channel to join together; and a second confluence channel connected to the second confluence portion on a downstream side of the second confluence portion to allow a liquid mixture of the first liquid and the second liquid having joined at the second confluence portion to flow through the second confluence channel, the channel structure includes a plurality of first boards and a plurality of second boards, and the first board and the second board are stacked alternately along respective thickness directions of the first board and the second board, each of the plurality of the first boards has a first board front surface and a first board back surface, and the first board front surface is one surface of the first board in the thickness direction of the first board while the first board back surface is the other surface opposite to the first board front surface, each of the plurality of the second boards has a second board front surface and a second board back surface, and the second board front surface is one surface of the second board in the thickness direction of the second board, the one surface being in close contact with the first board back surface of the first board stacked on the second board, while the second board back surface is the other surface opposite to the second board front surface, the other surface being in close contact with the first board front surface of the first board on which the second board is stacked, the first first-liquid introduction channels of the plurality of the first channels include a plurality of the first first-liquid introduction channels arranged along the first board front surface of each of the plurality of the first boards, the first second-liquid introduction channels of the plurality of the first channels include a plurality of the first second-liquid introduction channels arranged along the first board front surface of each of the plurality of the first boards, the first confluence channels of the plurality of the first channels include a plurality of the first confluence channels arranged along the second board front surface of each of the plurality of the second boards, the first confluence portions of the plurality of the first channels in each of the first boards are configured of a plurality of first confluence portion through-holes that penetrate the first board in the thickness direction of the first board, and the second first-liquid introduction channels of the plurality of the second channels and the second second-liquid introduction channels of the plurality of the second channels are arranged along the respective second board front surfaces of the plurality of the second boards, and are located in an area that is deviated from the plurality of the first confluence channels in a view in a direction along a stacking direction of the first board and the second board.

2 . The channel device according to claim 1 , wherein
the second confluence portions of the plurality of the second channels in each of the first boards are configured of a plurality of second confluence portion through-holes that penetrate the first board in the thickness direction of the first board, the second confluence channels of the plurality of the second channels include a plurality of the second confluence channels arranged along the first board front surface of each of the plurality of the first boards, and the plurality of the second confluence channels arranged along the first board front surface are located in an area that is deviated from the plurality of the first first-liquid introduction channels and the plurality of the first second-liquid introduction channels in a view in the direction along the stacking direction.

3 . The channel device according to claim 2 , wherein
the plurality of the first first-liquid introduction channels arranged along the first board front surface of each of the plurality of the first boards are configured of a plurality of first first-liquid introduction grooves formed on at least one of the first board front surface and the second board back surface in close contact with the first board front surface, the plurality of the first second-liquid introduction channels arranged along the first board front surface of each of the plurality of the first boards are configured of a plurality of first second-liquid introduction grooves formed on at least one of the first board front surface and the second board back surface in close contact with the first board front surface, the plurality of the first confluence channels arranged along the second board front surface of each of the plurality of the second boards are configured of a plurality of first confluence grooves formed on at least one of the second board front surface and the first board back surface in close contact with the second board front surface, the plurality of the second first-liquid introduction channels arranged along the second board front surface of each of the plurality of the second boards are configured of a plurality of second first-liquid introduction grooves formed on at least one of the second board front surface and the first board back surface in close contact with the second board front surface, the plurality of the second second-liquid introduction channels arranged along the second board front surface of each of the plurality of the second boards are configured of a plurality of second second-liquid introduction grooves formed on at least one of the second board front surface and the first board back surface in close contact with the second board front surface, and the plurality of the second confluence channels arranged along the first board front surface of each of the plurality of the first boards are configured of a plurality of second confluence grooves formed on at least one of the first board front surface and the second board back surface in close contact with the first board front surface.

4 . The channel device according to claim 3 , wherein
the first first-liquid introduction groove constituting the first first-liquid introd
