Condenser for refrigeration systems

Abstract

A condenser for refrigeration systems containing a refrigerant gas and applied to refrigeration appliances of the type comprising an internally refrigerated cabinet (G) presenting external walls ( 20 ) which are at least partially defined in a metallic and comprise at least one condensation coil (S) formed by a plurality of tube extensions ( 10 ) for conducting refrigerant gas and which are generally rectilinear and mutually coplanar, each of said tube extensions ( 10 ) being seated and retained inside a respective groove ( 21 ), which is formed by bending the metallic plate of a respective external wall ( 20 ) of the cabinet (G).

1 . A condenser for refrigeration systems containing a refrigerant gas and applied to refrigeration appliances of the type comprising an internally refrigerated cabinet (G) presenting external walls ( 20 ) which are at least partially defined in a metallic plate, characterized in that it comprises at least one condensation coil (S) formed by a plurality of tube extensions ( 10 ) for conducting a refrigerant gas, each of said tube extensions ( 10 ) being seated and retained inside a respective groove ( 21 ), which is formed by bending the metallic plate of a respective external wall ( 20 ) of the cabinet (G).  
   
   
       2 . The condenser as set forth in  claim 1 , characterized in that each groove ( 21 ) presents a cross section that is configured and dimensioned to contact more than half the external perimeter of the tube extension ( 10 ) that is seated and retained inside said groove ( 21 ).  
   
   
       3 . The condenser as set forth in  claim 2 , characterized in that each groove ( 21 ) presents an opening ( 21   a ) with a width smaller than the largest transversal dimension of the tube extension ( 10 ), taken at a direction that is parallel to the respective external wall ( 20 ).  
   
   
       4 . The condenser as set forth in  claim 3 , characterized in that the tube extensions ( 1 ) and the grooves ( 21 ) present a circular cross section.  
   
   
       5 . The condenser as set forth in  claim 1 , characterized in that the depth of the groove ( 21 ) is substantially similar to the largest transversal dimension of the tube extension ( 10 ), taken at a direction that is orthogonal to the respective external wall ( 20 ).  
   
   
       6 . The condenser as set forth in  claim 1 , characterized in that the groove ( 21 ) opens to the outside of the respective external wall ( 20 ) of the cabinet (G).  
   
   
       7 . The condenser as set forth in  claim 1 , characterized in that it comprises a condensation coil (S), whose tube extensions ( 10 ) are seated and retained in grooves ( 21 ), which are defined on an external wall ( 20 ) provided at the rear part of the cabinet (G).  
   
   
       8 . The condenser as set forth in  claim 7 , characterized in that it comprises an additional condensation coil (SI) arranged in series with the condensation coil (S) and whose tube extensions ( 10 ) are seated and affixed against the flat inner face of an external wall ( 20 ) that defines the top of the cabinet (G).  
   
   
       9 . The condenser as set forth in  claim 7 , characterized in that it comprises an additional condensation coil (S 2 ) arranged in series with the condensation coil (S) and whose tube extensions ( 10 ) are seated and affixed against the flat inner face of an external wall ( 20 ) that defines the bottom of the cabinet (G).  
   
   
       10 . The condenser as set forth in  claim 1 , characterized in that the grooves ( 21 ) are rectilinear and mutually coplanar.  
   
   
       11 . The condenser as set forth in  claim 8 , characterized in that it comprises an additional condensation coil (S 2 ) arranged in series with the condensation coil (S) and whose tube extensions ( 10 ) are seated and affixed against the flat inner face of an external wall ( 20 ) that defines the bottom of the cabinet (G).
