Abstract
A U-tube heat exchanger wherein a tube support plate divides the interior of a tube-exterior fluid chamber into a curved-tube chamber on a second end side including curved-tube sections of the U-tubes, and a chamber on a first end side. A second partition wall divides the interior of the chamber on the first end side inside the tube-exterior fluid chamber into a first straight-tube chamber including inlet-side straight-tube sections of the U-tubes, and a second straight-tube chamber including outlet-side straight-tube sections of the U-tubes. An opening penetrating from the first straight-tube chamber into the second straight-tube chamber is formed in the second partition wall. First passage holes, which penetrate from the first straight-tube chamber into the curved-tube chamber, and second passage holes, which penetrate from the second straight-tube chamber into the curved-tube chamber, are formed in the tube support plate.
