Heat Exchanger Structure

Abstract

The heat exchanger structure comprises a frame ( 2 ) inside which is arranged, parallel with each other, a plurality of radiating components ( 3 ) in which each radiating component ( 3 ) comprises a pair of basic components ( 3 a and 3 b ) coupled with each other symmetrically. The frame ( 2 ) is provided with at least one first cold liquid inlet duct ( 5 ) positioned below the base of the frame itself and at least one second hot liquid outlet duct ( 6 ) positioned above the top of the structure. Each basic component ( 3 a or 3 b ) comprises a plate ( 30 ) with, on its inner side, a plurality of primary wings ( 31 ) spaced equally from each other and positioned orthogonally to the plate itself and on the outer side a series of secondary wings ( 32 ) which are also positioned orthogonally to the plate ( 30 ) and spaced equally from each other but closer to each other with respect to the primary wings ( 31 ). Besides, the plate ( 30 ) is equipped with two projections ( 30 a and 30 b ) forming an arch, opposite each other and designed to couple with the corresponding projection present in the other basic component forming a channel ( 350 ).

Heat exchanger structure according to  claim 1 , characterised by the fact that the said first duct ( 5 ) is connected with the space ( 34 ) of each radiating component ( 3 ) by means of a first passage ( 35 ) present in the duct itself and through which the liquid from the duct ( 5 ) enters the first channel ( 350 ) created by the coupling of the projections ( 30   a ) in each radiating component present in the frame ( 2 ). 
   
   
       6 . Heat exchanger structure according to  claim 1 , characterised by the fact that the said second duct ( 6 ) is also connected to the space ( 34 ) in each radiating component ( 3 ) by means of a second passage ( 36 ) present in the duct ( 6 ) and through which the liquid from the second channel ( 350 ) created by the coupling of the projections ( 30   b ) exits into the duct ( 6 ) on the opposite side of the plate with respect to the passage ( 35 ). 
   
   
       7 . Heat exchanger structure according to  claim 1 , characterised by the fact that it is equipped with two first cold liquid inlet ducts ( 5 ) in the plurality of radiating components and two second ducts ( 6 ) for the liquid outlet that in the meantime has been heated by the plurality of radiating components. 
   
   
       8 . Heat exchanger structure according to  claim 1 , characterised by the fact that each basic component ( 3   a,    3   b ) is produced in extruded or moulded metal. 
   
   
       9 . Heat exchanger structure according to  claim 1 , characterised by the fact that it is achieved by the assembly of two basic components to obtain a radiating component ( 3 ) and the arrangement of a plurality of radiating components that are arranged vertically and parallel with each other for the overall structure.
