Abstract

An evaporator arrangement ( 1 ) for evaporating liquid fuel for a mobile fuel-operated heating device, comprising: an evaporator unit ( 5 ) for distributing and evaporating liquid fuel; and at least one fuel supply line ( 6 ) for delivering liquid fuel to the evaporator unit ( 5 ). The evaporator unit ( 5 ) has at least one first section (B 1 ) made of a metal wire mesh ( 8 ).

First claim

The invention claimed is:

1. An evaporator arrangement for evaporating liquid fuel for a mobile, fuel-operated heating device, having:
an evaporator body for distributing and evaporating liquid fuel and at least one fuel supply line for supplying liquid fuel to the evaporator body, wherein the evaporator body has at least a first region from a knitted metal wire fabric, and wherein the knitted metal wire fabric in the first region comprises a plastically deformed and compressed knitted metal wire fabric.

2. The evaporator arrangement as claimed in claim 1 , wherein the evaporator body has at least one additional region comprising knitted metal wire fabric having a porosity which is different from the first region.

3. The evaporator arrangement as claimed in claim 2 , wherein the knitted metal wire fabric has in the at least one additional region a degree of compression which is different from the knitted metal wire fabric in the first region and/or a different wire thickness.

4. The evaporator arrangement as claimed in claim 1 , wherein the knitted metal wire fabric is formed from a flat knitted fabric and/or a round knitted fabric.

5. The evaporator arrangement as claimed in claim 1 , wherein the wires of the knitted metal wire fabric are at least partially welded, soldered or sintered to each other.

6. The evaporator arrangement as claimed in claim 1 , wherein the evaporator body has at least a second region comprising a nonwoven metal fabric, a woven metal fabric, a metal braiding and/or a meshed metal fabric.

7. The evaporator arrangement as claimed in claim 6 , wherein the second region is connected to the first region by means of sintering, soldering or welding.

8. The evaporator arrangement as claimed in claim 1 , wherein the wires of the knitted metal wire fabric have a round or a flattened cross-sectional shape.

9. The evaporator arrangement as claimed in s claim 1 , wherein the evaporator arrangement has a cup-shaped evaporator accommodation in which the evaporator body is received and in which the fuel supply line opens.

10. The evaporator arrangement as claimed in one of claim 1 , wherein the evaporator arrangement has a rod-like evaporator holder against the outer periphery of which the evaporator body rests.

11. The evaporator arrangement as claimed in claim 1 , wherein a combustion air supply is provided for supplying combustion air to a side of the evaporator body facing away from the fuel supply line.

12. Mobile heating device having an evaporator arrangement as claimed in claim 1 .
