An airfoil having a leading edge and a trailing edge is provided. The airfoil includes a rear cooling path connected to the trailing edge to discharge air to the trailing edge, a plurality of cooling fins formed in the rear cooling path, and a flow guide rod connecting the cooling fins to support the cooling fins, wherein each of the plurality of cooling fins includes an upper fin portion protruding upward from an upper portion of the flow guide rod, a lower fin portion protruding downward from a lower portion of the flow guide rod, and an intermediate fin portion inserted through the flow guide rod.

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.
