Abstract

An evaporator comprising an evaporator body ( 3 ) surrounded by an evaporator housing ( 5 ), wherein the evaporator housing ( 5 ) is provided with a feed line ( 1 ) for feeding a liquid into the evaporator housing ( 5 ) and with an outlet ( 6 ) for emitting any vapour produced,
wherein the evaporator body ( 3 ) comprises a multiplicity of plates ( 7 ) which are arranged in a planar manner one above another, wherein a void ( 8 ) is formed in each case between adjacent plates ( 7 ), wherein each of the voids ( 8 ) is fluidically connected to the outlet,

wherein a liquid distributor is interconnected between the feed line ( 1 ) and the evaporator body ( 3 ), wherein the liquid distributor branches off from the feed line ( 1 ) in the direction of the evaporator body ( 3 ) in at least two distributor lines (VR), and

wherein each distributor line (VR) is connected to at least one void ( 8 ).

First claim

The invention claimed is:

1. An evaporator comprising an evaporator body surrounded by an evaporator housing, wherein the evaporator housing is provided with a feed line for feeding a liquid into the evaporator housing and then into the evaporator with an outlet for emitting any vapour produced,
wherein the evaporator body comprises a multiplicity of closed plates which are arranged in a planar manner one above another, wherein at least one separate void is formed in each case between adjacent closed plates, wherein each of the separate voids is fluidically connected to the outlet,
wherein a liquid distributor is interconnected between the feed line and the evaporator body, wherein the liquid distributor branches off from the feed line in the direction of the evaporator body in at least two distributor lines (VR), and
wherein each distributor line (VR) is connected to at least one separate void,
wherein a cross-sectional area of the feed line corresponds substantially to the sum of the cross-sectional areas of the distributor lines (VR).

2. The evaporator according to claim 1 , wherein a pressure loss between an end, facing the evaporator body, of the feed line and an end, facing the evaporator body, of each distributor line (VR) is substantially the same.

3. The evaporator according to claim 1 , wherein the distributor lines (VR) are substantially the same length and have the same cross section.

4. The evaporator according to claim 1 , wherein a pre-distributor structure is connected between the feed line and the distributor lines (VR), the feed line splitting up in a tree-like manner into a multiplicity of feed end lines in said pre-distributor structure, wherein each of the feed end lines is divided into at least two distributor lines (VR).

5. The evaporator according to claim 1 , wherein each distributor line (VR) leads into a cavity (VK), wherein the cavity (VK) is connected to a multiplicity of the voids.

6. The evaporator according to claim 5 , wherein the distributor lines (VR) extend in a plane perpendicular to the feed line and lead into the cavities (VK) perpendicularly to the extension direction.

7. The evaporator according to claim 6 , wherein an aperture plate (B 1 ) is arranged between the cavities (VK) and the channels (K).

8. The evaporator according to claim 5 , wherein an aperture plate (B 1 ) is arranged between the cavities (VK) and the channels (K).

9. The evaporator according to claim 1 , wherein the closed plates are provided with flow guiding elements.

10. The evaporator according to claim 1 , wherein channels (K) are formed integrally on the closed plates, wherein adjacent closed plates butt against one another directly in regions between the channels (K) such that a multiplicity of separate voids are formed between two adjacent closed plates, said voids being fluidically connected to the feed line and the outlet (A).

11. The evaporator according to claim 10 , wherein the channels (K) extend in parallel.

12. The evaporator according to claim 11 , wherein an aperture plate (B 1 ) is arranged between the cavities (VK) and the channels (K).

13. The evaporator according to claim 10 , wherein an aperture plate (B 1 ) is arranged between the cavities (VK) and the channels (K).
