A convector for air cooling of a fluid flowing in a pipe, comprising: a path for a cooling air flow comprising an inlet from and an outlet towards the environment, a heat exchange section comprising at least one tube bundle defining a heat exchange surface, said section being provided in said path for the air flow, fan means producing said air flow along said path, so that said air flow externally invests said tube bundle on said; heat exchange surface, a humidifying section arranged in said path, upstream of said heat exchange section, where water is atomized to be invested by the air flow, characterized by comprising a wetting device for wetting directly with water a portion of the heat exchange surface of said tube bundle to further cool said portion of tube bundle.

Combined convector

The convector includes at least one finned tube bundle () in the tubes of which a fluid to be cooled is made to circulate and at least one fan () producing an air flow that strikes the outside of said finned tubes. The convector includes an adiabatic chamber () through which a air flow (F) passes, positioned upstream of the tube bundle (), inside which water is nebulized and vaporized. The adiabatic chamber () is defined by side walls () and by at least two evaporation honeycomb fill packs ().
