<p>PURPOSE:To prevent corrosion or damage of a tube due to the contact of a turbulence facilitating part of a reflector with the inner wall of the tube and to prevent leakage of a heat exchange medium. CONSTITUTION:A tube 4 has an expanded-tube part 18 formed in the end part on the second tank 3 side. A reflector 21 has a wave-shaped turbulence facilitating part 23 being inserted into the tube 4 and also has a linear free end part 33 in the end part of the turbulence facilitating part 23. A guide 24 formed at the free end part 33 is disposed inside the expanded-tube part 18 and a space between this guide 24 and the inner wall of the expanded-tube part 18 is made smaller than a space between the turbulence facilitating part 23 and the inner wall of a non-expanded-tube part of the tube 4.</p> |
