Abstract

A fluid dispersing device includes a tubular first wall portion with an axis extending in a first direction defined as a central axis, and a second wall portion separated downward from the first wall portion. The second wall portion includes at least one circular member and a disk-like member each having a flat surface for causing a fluid passing through an inner space of the first wall portion to collide therewith. The disk-like member is separated downward from the at least one circular member. The at least one circular member has an outer diameter equal to or smaller than an inner diameter of the first wall portion. The disk-like member has an outer diameter equal to or smaller than an outer diameter of the closest circular member.

First claim

What is claimed is:

1. A fluid dispersing device comprising:
a first wall portion which is a tube, with an axis extending in a first direction defined as a central axis; and
a second wall portion separated downward from the first wall portion,
the second wall portion including at least one flat annular plate member and a disk-like member each having a continuous flat surface for causing a fluid which passes through an inner space of the first wall portion to collide therewith,
the disk-like member being separated downward from the flat annular plate member,
the flat annular plate member having an outer diameter equal to or smaller than an inner diameter of the first wall portion, and
the disk-like member having an outer diameter equal to or smaller than an outer diameter of the closest flat annular plate member,

wherein
the continuous flat surface of the at least one flat annular plate member is configured such that none of the fluid is allowed to pass through the at least one flat annular plate member, and
the continuous flat surface of the disk-like member is configured such that none of the fluid is allowed to pass through the disk-like member.

2. The fluid dispersing device according to claim 1 , wherein:
the flat annular plate member includes a first flat annular plate member having a first outer diameter and a first inner diameter, and a second flat annular plate member having a second outer diameter and a second inner diameter and separated from the first flat annular plate member downward in the first direction;
the first outer diameter is equal to or smaller than the inner diameter of the first wall portion;
the second outer diameter is smaller than the first outer diameter; and
the second inner diameter is equal to or smaller than the first inner diameter.

3. The fluid dispersing device according to claim 1 , wherein the first wall portion has an outer wall surface to be brought into contact with an inner wall surface of a pipe which is an installation portion so that the first wall portion is fixed to the pipe.

4. A fluid dispersing device comprising:
a tubular first wall portion with an axis extending in a first direction defined as a central axis; and
a second wall portion separated downward from the first wall portion, the second wall portion including a conical helical member and a disk-like member,
the disk-like member having a continuous flat surface for causing a fluid which passes through an inner space of the first wall portion to collide therewith,
the conical helical member forming a conical shape with an outer diameter and an inner diameter decreased gradually from an upstream side to a downstream side while making a circle about the central axis, the conical helical member having a continuous curved surface for causing the fluid to collide therewith, and
the disk-like member being located on the downstream side of the conical helical member,

wherein
the continuous curved surface of the conical helical member is configured such that none of the fluid is allowed to pass through the conical helical member, and
the continuous flat surface of the disk-like member is configured such that none of the fluid is allowed to pass through the disk-like member.

5. The fluid dispersing device according to claim 4 , wherein the first wall portion has an outer wall surface to be brought into contact with an inner wall surface of a pipe which is an installation portion so that the first wall portion is fixed to the pipe.

6. A heat treatment device utilizing heat exchange between a first fluid and a second fluid, the device comprising:
a heat exchange unit including a first heat transfer body including a plurality of first channels through which the first fluid flows, and a second heat transfer body including a plurality of second channels through which the second fluid flows, the first heat transfer body and the second heat transfer body being stacked with each other; and
a fluid introduction part having a space with an open surface on which openings of the respective first channels in the heat exchange unit are open, and introducing the externally-introduced first fluid to the respective first channels,
the fluid introduction part including the fluid dispersing device according to claim 1 to disperse the externally-introduced first fluid in the space.

7. A heat treatment device utilizing heat exchange between a first fluid and a second fluid, the device comprising:
a heat exchange unit including a first heat transfer body including a plurality of first channels through which the first fluid flows, and a second heat transfer body including a plurality of second channels through which the second fluid flows, the first heat transfer body and the second heat transfer body being stacked with each other; and
a fluid introduction part having a space with an open surface on which openings of the respective first channels in the heat exchange unit are open, and introducing the externally-introduced first fluid to the respective first channels,
the fluid introduction part including the fluid dispersing device according to claim 4 to disperse the externally-introduced first fluid in the space.
