Radiant module for a heating device for rooms, and method to produce said radiant module

Abstract

Radiant module and relative method of production, for a heating device for rooms, comprising two heat-conductor plates, respectively first and second, associated with each other to define a central portion inside which a heated heat-carrying fluid flows. The first heat-conductor plate comprises lateral walls which develop from the central portion away from the second heat-conductor plate, to define a channel inside the radiant module which develops and narrows from the lower part of the radiant module towards its upper part and through which a flow of heated air is accelerated and guided.

         6 . The radiant module as in  claim 1 , wherein said lateral walls are substantially symmetrical with respect to a longitudinal axis of said first heat-conductor plate. 
     
     
         7 . A heating device for rooms, comprising one or more radiant modules as in  claim 1 , wherein said radiant modules are connected fluid-dynamically with each other by connection means, wherein said heated heat-carrying fluid is able to flow, through said connection means, from one to the other of said radiant modules in order to heat the air of the surrounding environment, and wherein the lateral walls of the first heat-conductor plate of each radiant module are two, are substantially symmetrical with respect to a vertical axis of the first heat-conductor plate, and are shaped substantially orthogonal to the plane on which said second plate lies so as to extend towards the second heat-conductor plate of the adjacent radiant module and to define a channel, laterally closed and open at the top and at the bottom, which narrows from the lower to the upper part thereof. 
     
     
         8 . Device as in  claim 7 , wherein said lateral walls are distanced from the corresponding first heat-conductor plate by a distance substantially equal to the distance between the heat-conductor plates of two adjacent radiant modules. 
     
     
         9 . A method to produce a radiant module for a heating device for rooms, provided with two heat-conductor plates, respectively first and second, wherein said method comprises a coupling step, in which said heat-conductor plates are associated with each other so as to define a central portion inside which a heated heat-carrying fluid is made to flow, the method also comprising a shaping step, in which at least a first heat-conductor plate is shaped so as to define two lateral vertical walls, substantially symmetrical with respect to a vertical axis of the first heat-conductor plate, which develop from said central portion away from said second heat-conductor plate, substantially orthogonal to the plane on which said second plate lies and towards an adjacent module, in order to define a vertical channel inside the radiant module, the channel being laterally closed by the walls, frontally closed by the second plate of an adjacent module and open at the top and at the bottom, which develops from the lower part of said radiant module towards the upper part thereof and through which a flow of heated air is able to be accelerated and guided. 
     
     
         10 . The method as in  claim 9 , wherein the shaping step is carried out before the coupling step. 
     
     
         11 . The method as in  claim 9 , wherein the shaping step is carried out after the coupling step.
