In a heat exchanger, a thin tube plate is reinforced by means of a heavy support plate spaced therefrom. The tubes are fixed to the tube plate and pass through enlarged openings in the support plate but are anchored to the support plate by anchoring devices which allow the liquid to be heated to pass from the chamber provided between the two plates through the annular passages between the tubes and the enlarged openings of the support plate.
