FIELD: heating.
SUBSTANCE: heat exchanger comprising a bundle of tubes, placed inside a body, made with an elastic end structure put into compressed condition to form a plug, at least partially, on opposite sides of the heat exchange chamber. The specified elastic end structure comprises one or more edge segments stretching between the inner wall of the body and the outer border of the tube bundle. The edge segment includes a combination of materials, having different compression characteristics, providing for reinforced support to edge segments.
EFFECT: improved sealing properties of a heat exchanger.
