Method of increasing heat exchange surfaces and active surfaces of metal elements including, in particular, heat exchange surfaces

Abstract

The unique character of the method of remelting of a surface in the presence of a steam channel is related to the fact that during the remelting process a processed element is subject to vibrations. The vibrations parameters are uniform at any given point of the remelted element. The element surface remelting method is unique since the process is performed at a temperature below the ebullition temperature and duting the remelting process the element being processed is subject to vibrations. The surface is remelted using a laser or electron beam.

1 . The unique character of the invention is related to the fact that it increases heat the exchange surface of elements made of metal and metal alloys through remelting of a surface in the presence of a steam channel while the remelted element is subject to vibrations. 
     
     
         2 . The unique character of the method described in claim no.  1  is related to the fact that vibration parameters are the same at any point of the element. 
     
     
         3 . The unique character of the invention is related to the fact that it increases the active surface including, in particular, the heat exchange surface of elements made of metal or metal alloys, through remelting at a temperature below the ebullition temperature. At the same time the remelted element is subject to vibrations. 
     
     
         4 . The unique character of the method described in claim no.  3  is related to the fact that vibration parameters, frequency and amplitude, are selected to ensure uniformity thereof at any given point of the element. 
     
     
         5 . The unique character of the method described in claim no.  3  is related to the fact that a surface is remelted using a laser beam. 
     
     
         6 . The unique character of the method described in claim no.  3  is related to the fact that a surface is remelted using a beam of electrons.
