Heat exchange method for melting plate candle

Abstract

The present invention relates to melting plate candles which employ heat conductive elements to distribute heat from a burning flame at a wick to a support plate for a solid fuel and to the body of said solid fuel, so as to more rapidly liquefy the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to increase the efficiency of consumption thereof and to more rapidly release volatile materials contained within said fuels. The heat conductive support plate is configured so as to have a capillary pedestal upon the surface thereof, which cooperatively engages a wick holder comprising a preferably consumable wick and heat conductive fins which conduct heat from a flame upon said wick to said support plate, said wick holder further engaging said capillary pedestal in such a locking manner as to resist accidental removal from said pedestal. The fuel may be provided in various forms, configured to cooperatively engage said wick holder and support plate, and may comprise various volatile materials. The capillary pedestal, in conjunction with the wick holder, causes rapid and complete flow of the liquefied fuel to said wick.

       12 . The candle of  claim 10 , wherein said support plate further comprises a heat conductive portion by which heat is conducted from a flame upon said wick to said solid fuel element, whereby a pool of heated liquid fuel is created, said support plate being configured to cause the flow of said heated liquid fuel toward said wick holder.  
   
   
       13 . The candle of  claim 9 , wherein said support plate is treated so as to be self cleaning.  
   
   
       14 . A candle consisting of a fuel holder comprising a heat conductive surface shaped to hold and melt a solid fuel material included in a replaceable solid fuel element further comprising a wick holder including a wick and heat fins, and to form a pool of liquid fuel, said surface further comprising a capillary pedestal which lockingly engages said wick holder, wherein said heat fins are configured so as to come in close proximity to the hottest portion of a flame on said wick and to conduct heat from said flame to said fuel element, the tips of said heat fins being connected by heat conductive means passing directly through the hottest portion of said flame, and wherein said surface is shaped so as to cause said pool of liquid fuel to flow to said wick.  
   
   
       15 . The candle of  claim 14 , wherein said replaceable fuel element is configured to cooperatively engage said wick holder.  
   
   
       16 . The candle of  claim 14 , wherein said replaceable fuel element further comprises one or more volatile active materials.  
   
   
       17 . The candle of  claim 14 , wherein the replaceable fuel element further comprises a starter bump on the top surface thereof, in close proximity but not in contact with said wick for ease of lighting said wick.  
   
   
       18 . The candle of  claim 15 , wherein said heat conductive surface further comprises raised heat conductive areas.  
   
   
       19 . The candle of  claim 14 , wherein said heat conductive surface is treated so as to be self cleaning.
