Abstract

Disclosed are a heat exchange reactor and a method of manufacturing the same, and a method of manufacturing a heat exchange reactor includes: preparing lateral plates provided with a plurality of slits formed in parallel in a longitudinal direction; disposing two lateral plates to be spaced apart from each other while facing each other in a vertical direction; forming a plurality of flow path channels by inserting flow path partition plates into one or more slits of the two lateral plates in a horizontal direction; forming a plurality of flow path channels by inserting printed circuit heat exchange plates, which autonomously include one or more heat exchange flow paths therein, into one or more slits of the two lateral plates in a horizontal direction; and bonding the lateral plates, the flow path partition plates, and the printed circuit heat exchange plates.

First claim

What is claimed is:

1. A method of manufacturing a heat exchange reactor; comprising:
preparing two lateral plates provided with a plurality of slits formed in parallel in a longitudinal direction, wherein the slits are not formed in opposed end parts of the two lateral plates, wherein the slits are divided into slits for inserting flow path partition plates and slits for inserting printed circuit heat exchange plates;
disposing the two lateral plates, extending in a vertical direction and spaced apart from each other while facing each other;
forming a plurality of first flow path channels by inserting flow path partition plates into one or more slits of the slits for inserting flow path partition plates of the two lateral plates in a horizontal direction;
forming a plurality of second flow path channels dividing the plurality of first flow path channels by inserting printed circuit heat exchange plates, which autonomously include one or more heat exchange flow paths therein, into one or more slits of the slits for inserting printed circuit heat exchange plates of the two lateral plates in the horizontal direction;
bonding the lateral plates, the flow path partition plates, and the printed circuit heat exchange plates; and
cutting the opposed end parts of the two lateral plates, in which the slits are not formed, after bonding the lateral plates, the flow path partition plates, and the printed circuit heat exchange plates, such that the lateral plates do not extend beyond the flow path partition plates and the printed circuit heat exchange plates in the longitudinal direction.

2. The method of claim 1 , wherein the two lateral plates are finished by the printed circuit heat exchange plates so that upper ends and lower ends of the two lateral plates are connected with each other, so that the printed circuit heat exchange plates are configured as an upper plate and a lower plate as the heat exchange reactor.

3. The method of claim 1 , wherein the flow path partition plates and the printed circuit heat exchange plates are alternately disposed.

4. The method of claim 1 , wherein thicknesses of each flow path partition plate and each slit for inserting the flow path partition plate are 0.1 to 0.5 mm respectively.

5. The method of claim 1 , wherein thicknesses of each printed circuit heat exchange plate and each slit for inserting the printed circuit heat exchange plate are 1 to 3 mm respectively.

6. The method of claim 1 , wherein a thickness of each lateral plate is 1 to 3 mm.

7. The method of claim 1 , wherein a length of each end part of each lateral plate is 5 to 10 mm.

8. The method of claim 1 , further comprising:
detachably inserting a heat exchange pin structure body having a shape, in which ribs and grooves are repeatedly connected, into one or more flow path channels of the plurality of second flow path channels.

9. The method of claim 8 , wherein the heat exchange pin structure body is a heat exchange pin structure body for reaction on which a catalyst is coated or supported.
