Abstract

Disclosed is a micro mixer which includes a mixing plate (14) with a first channel-forming section and a second channel-forming section. The first channel-forming section has a first channel formed for a first fluid to flow therethrough, while the second channel-forming section has a second channel formed for a second fluid to flow therethrough. Between the first channel-forming section and the second channel-forming section, there is provided a combined channel in which the first fluid and the second fluid merge with each other. The outlet of the first channel and the outlet of the second channel are opposed to each other with the combined channel disposed therebetween. The position of the outlet of the first channel facing the center axis of the combined channel is included in or the same as the position of the outlet of the second channel facing the center axis.

Claims

1. A micro mixer, configured to mix more than two types of fluids, wherein the micro mixer comprises:

a mixing plate having a first channel-forming section and a second channel-forming section, a first channel for a first fluid to flow therethrough is formed at the first channel-forming section, a second channel for a second fluid to flow therethrough is formed at the second channel-forming section; and

a combined channel disposed between the first channel-forming section and the second channel-forming section and at which the first fluid and the second fluid are merged, wherein an outlet of the first channel and an outlet of the second channel are opposed to each other with the combined channel disposed therebetween, and a position of the outlet of the first channel facing a center axis of the combined channel is included in or the same as a position of the outlet of the second channel facing the center axis,

wherein the mixing plate consists of a pair of plates, a width of the combined channel is configured by adjusting a distance between the pair of plates.

2. The micro mixer according to claim 1, wherein a center axis of a cross-section of the outlet of the first channel and a center axis of a cross-section of the outlet of the second channel are the same.

3. The micro mixer according to claim 1, wherein an outlet surface of the first channel is parallel to an outlet surface of the second channel.

4. The micro mixer according to claim 1, wherein the outlet of the first channel is one of a plurality of outlets, the outlet of the second channel is one of a plurality of outlets, and the outlets of the first channel and the outlets of the second channel are configured oppose to each other and in a one-to-one relationship.

5. The micro mixer according to claim 4, wherein the combined channel is formed in an elongated shape, at a side surface of a pair of opposite side surfaces which form the combined channel, the plurality of outlets of the first channel are arranged side by side along a longitudinal direction of the combined channel, and at another side surface of the pair of opposite side surfaces, the plurality of outlets of the second channel are arranged side by side along the longitudinal direction of the combined channel.

6. The micro mixer according to claim 1, further comprising a temperature control plate laminated to the mixing plate, wherein the temperature control plate comprises a first medium channel for a first medium to flow therethrough, a second medium channel for a second medium to flow therethrough, and a heat insulating section disposed between the first medium channel and the second medium channel,

in a condition that the mixing plate and the temperature control plate are laminated, the first channel-forming section and the first medium channel are disposed to correspond to a lamination direction, and the second channel-forming section and the second medium channel are disposed to correspond to the lamination direction.

7. The micro mixer according to claim 1, wherein in the first channel and the second channel, a cross-section area of the outlet is smaller than a cross-section area of the inlet.

8. The micro mixer according to claim 2, wherein an outlet surface of the first channel is parallel to an outlet surface of the second channel.
