  • a heat exchanger of the prior art has sector columnar tank chambers 1 to 4.
  • the tank chambers 1 and 4 are separated from each other by a partition wall 5, while the tank chambers 2 and 3 are separated from each other by a partition wall 6.
  • the tank chambers 1 and 2 are provided with inlet pipes 7 and 8, respectively, while the tank chambers 3 and 4 are provided with outlet pipes 9 and 10, respectively.
  • a cap 11 is provided on the tank chamber 1.
  • the tank chambers 1 and 3 are connected to each other by annular tubes 12.
  • the tank chambers 2 and 4 are connected to each other by annular tubes 13.
  • Fin plates 14 are attached to the annular tubes 12, 13 and are arranged radially.
  • the annular tubes 12 and the fin plates 14 in combination constitute a first heat exchanging unit 15 while the annular tubes 13 in cooperation with the fin plates 14 constitute a second heat exchanging unit 16.
  • the first and the second heat exchanging units 15 and 16 are arrayed in the axial direction.
  • Side walls 17 and 18 are secured by means of bolts 19 to both sides of the tank chambers 1 to 4.
  • a reference numeral 20 designates a shaft extending through the side wall 17 and connected to a prime mover (not shown).
