Abstract

In an example, a condenser apparatus to condense vapored fluid has a gas inlet, a mesh, a cooling element, and a gas outlet. The mesh is configured to carry a layer of condensed fluid. The cooling element is configured to cool the layer of condensed fluid. The mesh is configured to let pass through vapored fluid and to create bubbles including vapored fluid in the layer of condensed fluid.

First claim

The invention claimed is:

1. A condenser apparatus to condense vapored fluid, the condenser apparatus comprising:
a gas inlet to receive vapored fluid,
a mesh vertically arranged above the gas inlet, the mesh to support a layer of condensed fluid on a side of the mesh opposite the gas inlet, prevent the condensed fluid from passing through, let the vapored fluid pass through, and create bubbles including the vapored fluid in the layer of condensed fluid,
a cooling element vertically arranged above the mesh to cool the layer of condensed fluid, and
a gas outlet vertically arranged above the cooling element.

2. The condenser apparatus according to claim 1 , wherein the gas inlet, the mesh, the cooling element and the gas outlet are vertically arranged above each other in this order.

3. The condenser apparatus according to claim 1 , wherein the condenser apparatus comprises a condensed fluid spillway to spill condensed fluid.

4. The condenser apparatus according to claim 3 , wherein the condensed fluid spillway is arranged between the cooling element and the gas outlet.

5. The condenser apparatus according to claim 3 , wherein the condensed fluid spillway is to limit a thickness of the layer of condensed fluid supported by the mesh.

6. The condenser apparatus according to claim 3 , wherein the condensed fluid spillway is vertically arranged above the mesh.

7. The condenser apparatus according to claim 3 , wherein the mesh, the cooling element, and the condensed fluid spillway are vertically arranged above each other in this order.

8. The condenser apparatus according to claim 1 , wherein the cooling element is a contact cooling element, wherein the cooling element is to immerse in the layer of condensed fluid supported by the mesh.

9. The condenser apparatus according to claim 1 , wherein the mesh comprises at least one of stainless steel fibers, brass fibers, glass fibers, sintered brass and sintered glass.

10. The condenser apparatus according to claim 1 , wherein the mesh comprises a mesh size of at least one of 1 μm, 5 μm, 10 μm, 50 μm, 100μ, 200μ, 300μ, 500μ and 1000μ.

11. The condenser apparatus according to claim 1 , wherein the fluid comprises oil.

12. A method of condensing vapored fluid by a condenser apparatus, the condenser apparatus comprising a gas inlet, a mesh vertically arranged above the gas inlet, a cooling element vertically arranged above the mesh, and a gas outlet vertically arranged above the cooling element;
the method comprising:
supporting, by the mesh, a layer of condensed fluid on a side of the mesh opposite the gas inlet;
cooling, by the cooling element, the layer of condensed fluid;
preventing the condensed fluid from passing through the mesh;
receiving, through the gas inlet, vapored fluid;
passing the vapored fluid through the mesh; and
creating, by the mesh, bubbles including the vapored fluid in the layer of condensed fluid.

13. The method of condensing vapored fluid according to claim 12 , the method further comprising immersing the cooling element in the layer of condensed fluid supported by the mesh.

14. The method of condensing vapored fluid according to claim 12 , wherein the method further comprises limiting, by a spillway, a thickness of the layer of condensed fluid.

15. The method of condensing vapored fluid according to claim 14 , wherein the spillway is arranged between the cooling element and the gas outlet.

16. The method of condensing vapored fluid according to claim 14 , wherein the spillway is vertically arranged above the mesh.

17. The method of condensing vapored fluid according to claim 14 , wherein the mesh, the cooling element, and the condensed fluid spillway are vertically arranged above each other in this order.

18. A printing system comprising
a printer to print using a printing fluid; and
a condenser apparatus to condense vapored printing fluid, the condenser apparatus comprising:
a gas inlet to receive the vapored printing fluid,
a mesh vertically arranged above the gas inlet, the mesh to support a layer of condensed printing fluid on a side of the mesh opposite the gas inlet, prevent the condensed printing fluid from passing through, let the vapored printing fluid pass through, and create bubbles including the vapored printing fluid in the layer of condensed printing fluid,
a cooling element vertically arranged above the mesh to cool the layer of condensed printing fluid, and
a gas outlet vertically arranged above the cooling element.

19. The printing system according to claim 18 , the condenser apparatus further comprising:
a spillway vertically arranged above the cooling element to limit a thickness of the layer of condensed printing fluid supported by the mesh.

20. The printing system according to claim 18 , wherein the spillway is arranged between the cooling element and the gas outlet.
