Energy exchanging apparatus

Abstract

An energy exchanging apparatus is constructed to include an energy source adapted for providing/delivering energy, a shell provided around the energy source and adapted for delivering a fluid to make an energy exchanging action with the energy source, and a spiral member provided inside the shell and spirally extended around the periphery of the energy source and defining a spiral flow path for guiding the fluid spirally over the periphery of the energy source.

What is claimed is:  
     
         1 . An energy exchanging apparatus comprising: 
 an energy source adapted for providing energy;    a shell provided around said energy source and adapted for delivering a fluid over the periphery of said energy source to make an energy exchanging action with said energy source; and    a spiral member provided between said energy source and said shell, said spiral member defining a spiral flow path adapted for guiding a fluid over the periphery of said energy source.    
     
     
         2 . The energy exchanging apparatus as claimed in  claim 1 , wherein said energy source comprises a plurality of fins respectively protruded into said spiral flow path.  
     
     
         3 . The energy exchanging apparatus as claimed in  claim 1 , wherein said energy source delivers a cooling agent.  
     
     
         4 . The energy exchanging apparatus as claimed in  claim 1 , wherein said energy source is an electric heating tube.  
     
     
         5 . The energy exchanging apparatus as claimed in  claim 1 , wherein said energy source is adapted to transmit infrared light and ultraviolet light and said energy source is made of transparent materials.  
     
     
         6 . The energy exchanging apparatus as claimed in  claim 1 , wherein said energy source is adapted to transmit a high voltage.  
     
     
         7 . The energy exchanging apparatus as claimed in  claim 1 , wherein said shell has one end terminating in an inlet, and an opposite end terminating in an outlet.  
     
     
         8 . The energy exchanging apparatus as claimed in  claim 1  further comprising sealing member sealed between said shell and said energy source.  
     
     
         9 . The energy exchanging apparatus as claimed in  claim 1 , wherein said shell comprises a plurality of fins protruded from an inside wall thereof and suspended in said spiral flow path.  
     
     
         10 . The energy exchanging apparatus as claimed in  claim 1 , wherein said spiral member is extended spirally around the periphery of said energy source.  
     
     
         11 . The energy exchanging apparatus as claimed in  claim 1 , wherein said spiral member comprises a plurality of fins respectively projecting into said flow path.  
     
     
         12 . The energy exchanging apparatus as claimed in  claim 1 , wherein said spiral member is formed integral with an inside wall of said shell.  
     
     
         13 . The energy exchanging apparatus as claimed in  claim 1 , wherein said spiral member is formed of at least two sub-spiral member.
