摘要
The group of inventions relates to heat exchange apparatus, and more particularly to condenser devices. The technical result of the group of inventions is that of reducing the risk of an increase in thermal resistance between the tube-side and shell-side heat transfer fluids of a shell and tube condenser. A condenser comprises a housing with tubes that have grooves on the outer surface thereof, baffles, and inlet and outlet manifolds for tube-side and shell-side heat transfer fluids. In contrast to the prior art, the tubes are coated on the outside with a material having a low wetting coefficient, and the distance between the baffles decreases from the shell-side heat transfer fluid inlet manifold to the shell-side heat transfer fluid outlet manifold. The condenser further differs from the prior art in that the tubes have protuberances on the inner surface thereof and are coated on the inside with a material having a high adhesion resistance coefficient.
