Abstract

A printed circuit-type heat exchanger includes a vaporizer having a structure in which one or more A-channel plates and one or more B-channel plates are sequentially stacked, to vaporize a fluid A with heat exchange through the A-fluid channels. A gas-liquid separator separates the fluid A into a vaporized gas and a non-vaporized liquid and includes a gas outlet for the vaporized gas and a liquid outlet for non-vaporized liquid. A super heater, having the same structure as the vaporizer, super heats the vaporized gas with heat exchange through the A-fluid channels and discharges the superheated gas through a gas outlet communicating with the outside. A first intermediate plate is disposed between the vaporizer and the gas-liquid separator to separate the vaporizer from the gas-liquid separator, and a second intermediate plate is disposed between the gas-liquid separator and the super heater to separate the super heater from the gas-liquid separator.

First claim

What is claimed is:

1. A printed circuit-type heat exchanger in which an A-fluid channel and a B-fluid channel are formed to exchange heat between a fluid A and a fluid B, the heat exchanger comprising:
a vaporizer having a structure in which one or more A-channel plates and one or more B-channel plates are sequentially stacked, the A-channel plates of the vaporizer each having an A-fluid channel and the B-channel plates of the vaporizer each having an B-fluid channel intersecting with the A-fluid channel of the vaporizer, the vaporizer configured to vaporize the fluid A with heat exchange through the A-fluid channels and to pass the vaporized fluid A through an A-fluid outlet;
a gas-liquid separator provided next to the vaporizer to separate the fluid A transferred from the vaporizer into a vaporized gas and a non-vaporized liquid, the gas-liquid separator including:
an upper side,
a lower side disposed opposite to the upper side,
lateral sides respectively connecting opposite ends of the upper side to opposite ends of the lower side,
a gas outlet formed through the upper side and configured to pass the vaporized gas of the fluid A outside the gas-liquid separator in a first direction,
a liquid outlet formed through the lower side and configured to discharge the non-vaporized liquid of the fluid A outside the gas-liquid separator in a direction opposite to the first direction,
an internal space to perform a gas-liquid separating function, the internal space extending in the first direction from the upper side to the lower side and extending between the lateral sides in a second direction perpendicular to the first direction, and
a baffle for separating a gas in the fluid A transferred from the vaporizer, the baffle disposed inside the internal space on the upper side of the gas-liquid separator, the baffle being disposed adjacent to the gas outlet formed on the upper side of the gas-liquid separator and opposite to the liquid outlet formed on the lower side of the gas-liquid separator to improve the gas-liquid separating function; and
a super heater provided next to the gas-liquid separator having a structure in which one or more A-channel plates and one or more B-channel plates are sequentially stacked, the A-channel plates of the super heater each having an A-fluid channel and the B-channel plates of the super heater each having a B-fluid channel intersecting with the A-fluid channel of the super heater, the super heater configured to super heat the vaporized gas transferred from the gas-liquid separator with heat exchange through the A-fluid channels, and including a gas outlet formed on one side through which the superheated gas is discharged,
wherein the baffle includes a continuous surface facing toward the A-fluid outlet of the vaporizer, the continuous surface extending from the upper side of the gas-liquid separator toward the lower side of the gas-liquid separator and extending between the lateral sides of the gas-liquid separator.

2. The printed circuit-type heat exchanger of claim 1 , further comprising:
a first intermediate plate disposed between the vaporizer and the gas-liquid separator to separate the vaporizer from the gas-liquid separator, the first intermediate plate including a fluid connection path so that the A-fluid outlet of the vaporizer communicates with the gas-liquid separator.

3. The printed circuit-type heat exchanger of claim 1 , further comprising:
a second intermediate plate disposed between the gas-liquid separator and the super heater to separate the super heater from the gas-liquid separator, the second intermediate plate including a fluid connection path so that an inlet of the super heater for the vaporized fluid A communicates with the gas-liquid separator.

4. The printed circuit-type heat exchanger of claim 1 , wherein the gas-liquid separator has a sufficient width to separate the vaporizer and the super heater by a predetermined distance in a third direction perpendicular to both the first and second directions.

5. The printed circuit-type heat exchanger of claim 1 , wherein the baffle is disposed adjacent to the gas outlet of the gas-liquid separator.

6. The printed circuit-type heat exchanger of claim 1 , wherein the vaporizer is detachably attached to one side of the gas-liquid separator.

7. The printed circuit-type heat exchanger of claim 1 , wherein the super heater is detachably attached to one side of the gas-liquid separator.

8. The printed circuit-type heat exchanger of claim 1 , wherein the A-fluid channel of each A-channel plate includes a series of bends in alternating directions.

9. The printed circuit-type heat exchanger of claim 8 , wherein the bends form a continuous path following a zigzag pattern.
