Shell and tube condenser and shell and tube condenser heat exchange tubes (multiple versions)

摘要

The present invention group relates to a heat exchange device, and more particularly to a condensing device. The technical result of the present invention group is that the risk of increasing thermal resistance is reduced between the heat transfer fluid on the tube side and the shell side of the shell-and-tube condenser. The condenser includes a housing including a tube having a groove on an outer surface thereof, a baffle, and a tube side and shell side heat transfer fluid supply port and a discharge port manifold. In contrast to the prior art, the outside of the tube is coated with a material with a low wetting coefficient, and the distance between the baffles is reduced from the shell side heat transfer fluid supply manifold to the shell side heat transfer fluid discharge manifold. Yes. Furthermore, this condenser differs from the prior art in that the tube has a protubal balance on its inner surface and the inner surface is coated with a material having a high viscosity resistance coefficient.
