Evaporator burner for a mobile heating device

Abstract

An evaporator burner for a mobile heating device is provided, with: a combustion chamber surrounding a combustion space for converting fuel with combustion air; an evaporator receiving portion for receiving an evaporator body for evaporating liquid fuel, the evaporator receiving portion being arranged at a rear side of the combustion space; a burner cap which closes the combustion space at the rear side of the evaporator receiving portion and which is connected to the combustion chamber; and a fuel pipe for supplying fuel to the evaporator body, the fuel pipe opening into the evaporator receiving portion. The fuel pipe is thermally coupled to the burner cap and the burner cap is provided with an air heat exchanger for cooling the burner cap over which supplied combustion air is guidable during operation.

1 . An evaporator burner for a mobile heating device, comprising:
 a combustion chamber surrounding a combustion space for converting fuel with combustion air;   an evaporator receiving portion for receiving an evaporator body for evaporating liquid fuel, the evaporator receiving portion being arranged at a rear side of the combustion space;   a burner cap which closes the combustion space at the rear side of the evaporator receiving portion and which is connected to the combustion chamber; and   a fuel pipe for supplying fuel to the evaporator body, the fuel pipe opening into the evaporator receiving portion;   wherein the fuel pipe is thermally coupled to the burner cap and the burner cap is provided with an air heat exchanger for cooling the burner cap over which supplied combustion air is guidable during operation.   
     
     
         2 . The evaporator burner according to  claim 1 , wherein the burner cap is connected to the combustion chamber only via one substantially line-shaped junction. 
     
     
         3 . The evaporator burner according to  claim 1 , wherein the air heat exchanger comprises a plurality of heat exchanger fins. 
     
     
         4 . The evaporator burner according to  claim 1 , wherein the air heat exchanger is arranged in the combustion air supply upstream of the combustion space. 
     
     
         5 . The evaporator burner according to  claim 1 , wherein the burner cap is made from aluminum or from an aluminum alloy. 
     
     
         6 . The evaporator burner according to  claim 1 , wherein the burner cap and the evaporator receiving portion are formed as separate components. 
     
     
         7 . The evaporator burner according to  claim 6 , wherein the burner cap and the evaporator receiving portion are arranged spatially spaced from each other. 
     
     
         8 . The evaporator burner according to  claim 1 , wherein the combustion chamber comprises a plurality of holes for supply of combustion air into the combustion space.
