a space-forming part having a space facing channel openings of the respective first channels; a first opening located in the space-forming part and having a first aperture; a flow-regulating part installed in the space in the space-forming part to regulate a flow of the first fluid; and an attachment part for removably attaching the flow-regulating part through the first aperture, wherein the space in the space-forming part is a space in which first fluid led out of the respective channel openings flows together, or a space from which the first fluid flowing together is introduced to the respective channel openings, and in a state in which the flow-regulating part is fixed in the space-forming part, the flow-regulating part is opposed to the plural channel openings. ## Claims ### Claim 1 A heat treatment apparatus using heat exchange between a first fluid and a second fluid, the apparatus comprising: a heat exchange unit including a plurality of first channels through which the first fluid flows and a plurality of second channels through which the second fluid flows; a space-forming part having a space facing channel openings of the respective first channels; a first opening located in the space-forming part and having a first aperture; a flow-regulating part installed in the space in the space-forming part to regulate a flow of the first fluid; and an attachment part for removably attaching the flow-regulating part through the first aperture, wherein the space in the space-forming part is a space in which the first fluid led out of the respective channel openings flows together, or a space from which the first fluid flowing together is introduced to the respective channel openings, and in a state in which the flow-regulating part is fixed in the space-forming part, the flow-regulating part is opposed to the plural channel openings. ### Claim 2 (depends on 1) The heat treatment apparatus according to claim 1, wherein an extending direction of a central axis of the first aperture is different from an open direction of the respective channel openings. ### Claim 3 (depends on 1) The heat treatment apparatus according to claim 1, wherein the flow-regulating part has a cylindrical shape. ### Claim 4 (depends on 1) The heat treatment apparatus according to claim 1, wherein the flow-regulating part is a porous member provided with a plurality of holes through which the first fluid can flow. ### Claim 5 (depends on 1) The heat treatment apparatus according to claim 1, wherein the first opening includes a first connection part connected to and released from an external pipe outside the apparatus through which the first fluid flows. ### Claim 6 (depends on 5) The heat treatment apparatus according to claim 5, wherein: the attachment pan includes an engaging part integrally provided at one end of the flow-regulating part so as to have a length from a central axis of the flow-regulating part greater than a radius of the first aperture, and an engaged part provided in the first connection part and engaged with the engaging part; and in a state in which the engaging part engages with the engaged part, the first connection part is connected to the external pipe outside the apparatus so as to fix the flow-regulating part. ### Claim 7 (depends on 1) The heat treatment apparatus according to claim 1, further comprising: a second opening including a first connection part connected to and released from an external pipe outside the apparatus through which the first fluid flows; and a shielding plate capable of shielding the first aperture, wherein the first opening includes a second connection pan connected to and released from the shielding plate. ### Claim 8 (depends on 7) The heat treatment apparatus according to claim 7, wherein: the attachment part includes an engaging part integrally provided at one end of the flow-regulating part so as to have a length from a central axis of the flow-regulating part greater than a radius of the first aperture, and an engaged part provided in the second connection part and engaged with the engaging part; and in a state in which the engaging part engages with the engaged part, the second connection part is connected to the shielding part so as to fix the flow-regulating part. ### Claim 9 (depends on 7) The heat treatment apparatus according to claim 7, wherein: the first opening is opposed to the second opening on an identical axis; and another end of the flow-regulating part is introduced into a second aperture of the second opening in the state in which the flow-regulating part is fixed in the space-forming part.
