A radiator with reduced thermal inertia, based on the principle of phase changing, using a non-toxic, non-flammable fluid with reduced environmental impact. The radiator is provided by means of vertical pipes which engage a collector containing a pipe bundle-type exchanger with smooth or finned pipes, internally crossed by the thermo-vector fluid of the system, and which heat the intermediate vector fluid, bringing it to the biphasic state. The vector fluid evaporates, rising up the vertical pipes, flowing through the channels obtained in the extruded profiles of the vertical pipes themselves. The fluid re-descends, condensing on the walls, returning into contact with the hot pipes of the exchanger in order to re-evaporate and rise back up the vertical pipes. The film of condensed liquid provides the required heat exchange. The terminal is further equipped with mechanical parts which allow the inserting of temperature sensors for possible monitoring and control of consumption and system operation and control thereof, by means of on-board electronic control devices (electric valves) and remote devices suitably operating in radio-frequency.

Hydronic/biphasic radiator with reduced thermal inertia and low environmental impact

A radiator of the thermosiphon type comprising a collector situated in the lowest part of the radiator, and adapted to contain an intermediate vector fluid, an external heat source, placed within the collector, wherein the intermediate vector fluid is adapted to evaporate on contact with a hot surface of the external heat source, at least one vertical tube containing therein one or more channels () connected to the collector and communicating with the same, characterized in that said collector and said channels are dimensioned so that each section thereof crossed by the intermediate vector fluid, excluding the thickness of the liquid film of moisture, has the smallest linear direction which is twice bigger than the diameter db of an intermediate fluid vapor bubble which, during operation, detaches itself from the hot surface of the external source during boiling of the intermediate fluid.

Biphasic heat exchange radiator with optimisation of the boiling transient

A tubular section bar () for a biphasic&#x2267;radiator comprising a tubular body () having a perimeter surface, a surface lug (-) protruding from at least one portion of said perimeter surface; each lug is perpendicular to the perimeter surface and has a height (H); two consecutive lugs are arranged at a reciprocal distance (D) and so that the relation between the reciprocal distance (D) and height (H) is greater or equal to 1.4 (D:H&#x2267;1,4).
