Abstract

The invention relates to a module for a heat pump, comprising an adsorption-desorption region, wherein in the region a bundle of pipes through which fluid can flow is arranged and a housing encloses the pipe bundle and a movable working medium in a sealing manner, wherein a supporting structure forms a mechanical support of a wall of the housing against the action of an external pressure.

First claim

The invention claimed is:

1. A module for a heat pump, comprising:
a housing;
an adsorption/desorption region, wherein in the adsorption/desorption region, a bundle of tubes through which fluid can flow is arranged;
a supporting structure that forms a mechanical support for a wall of the housing against an action of an external pressure;
a first tube sheet having first rim holes that each retain a first end of respective tubes of the bundle of tubes; and
a second tube sheet having second rim holes that each retain a second end of the respective tubes of the bundle of tubes,
wherein the housing encloses the bundle of tubes and a movable working medium in a sealing manner, and
wherein the supporting structure is arranged parallel to a longitudinal extent of the bundle of tubes, the longitudinal extent of the bundle of tubes being a direction from the first end of the respective tubes to the second end of the respective tubes, such that the supporting structure extends from the first tube sheet to the second tube sheet.

2. The module as claimed in claim 1 , further comprising a condensation/evaporation region that is provided in the housing and in which the bundle of tubes through which the fluid can flow is arranged, wherein the working medium is movable between the adsorption/desorption region and the condensation/evaporation region.

3. The module as claimed in claim 2 , wherein in the condensation/evaporation region, there is no support by the bundle of tubes for an accumulation and release of the working medium.

4. The module as claimed in claim 2 , wherein the adsorption/desorption region occupies a larger proportion of the module than the condensation/evaporation region, and wherein a ratio of the volumes taken up by each of these regions within the housing is between 2 and 4.

5. The module as claimed in claim 2 , wherein the supporting structure is positioned between the adsorption/desorption region and the condensation/evaporation region.

6. The module as claimed in claim 5 , further comprising a second supporting structure, the second supporting structure being positioned in the adsorption/desorption region.

7. The module as claimed in claim 1 , further comprising an adsorber structure comprising:
an adsorbent, wherein the working medium can be adsorbed and desorbed on the adsorbent, and the adsorbent is thermally connected to at least one tube of the bundle of tubes in the adsorption/desorption region,
wherein the adsorbent is formed as at least one shaped body which directly adjoins a tube wall of the at least one tube of the bundle of tubes.

8. The module as claimed in claim 7 , wherein the at least one shaped body forms a mechanical support for a wall of the housing against the action of the external pressure.

9. The module as claimed in claim 7 , wherein the at least one shaped body rests against the tube wall of the at least one tube of the bundle of tubes under the action of a force by frictional engagement.

10. The module as claimed in claim 9 , wherein at least one of the two, namely the tube or the shaped body, has a substantially wedge-shaped cross section, wherein, in particular, at least one of the two is held under the action of a force in a wedging direction.

11. The module as claimed in claim 7 , wherein the at least one tube of the bundle of tubes is designed as a flat tube and the at least one shaped body adjoins a broad side of the flat tube.

12. The module as claimed in claim 7 , wherein the tube is designed substantially as a round tube or polygonal tube, wherein the tube is embedded in two or more shaped bodies.

13. The module as claimed in claim 7 , wherein the flat tube is composed of an iron-based alloy which is coated for the purpose of joining and/or for corrosion resistance.

14. The module as claimed in claim 13 , wherein the shaped bodies in which the tube is embedded have a polygonal, in particular hexagonal, external outline overall.

15. The module as claimed in claim 14 , wherein the shaped bodies are adhesively bonded to the tubes by means of a thermoplastic adhesive, e.g. a silicone-based adhesive.

16. The module as claimed in claim 15 , wherein the adhesive has a low density of uncrosslinked molecules.

17. The module as claimed in claim 13 , wherein the shaped body is of substantially plate-shaped design, wherein it has in each case a plurality of indentations for partially surrounding some of the tubes.

18. The module as claimed in claim 1 , wherein the housing wall is composed of an iron-based alloy, and wherein the housing wall is painted on the outside.

19. The module as claimed in claim 1 , wherein no Ti-stabilized steels and/or stainless steels are used in assembling a tube/sheet and a sheet/housing joint by soft soldering.

20. The module as claimed in claim 1 , wherein the housing is embodied as a single-shell housing formed by hydroforming.

21. The module as claimed in claim 7 , wherein the at least one shaped body is a plate-shaped body.

22. A module for a heat pump, comprising:
a housing;
an adsorption/desorption region, wherein in the adsorption/desorption region, a bundle of tubes through which fluid can flow is arranged; and
a supporting structure that forms a mechanical support for a wall of the housing against an action of an external pressure,
wherein the housing encloses the bundle of tubes and a movable working medium in a sealing manner, and
wherein the supporting structure is arranged parallel to a longitudinal extent of the bundle of tubes,

the module further comprising an adsorber structure comprising:
an adsorbent, wherein the working medium can be adsorbed and desorbed on the adsorbent, and the adsorbent is thermally connected to at least one tube of the bundle of tubes in the adsorption/desorption region,
wherein the adsorbent is formed as at least one shaped body which directly adjoins a tube wall of the at least one tube of the bundle of tubes,
wherein the at least one shaped body is a plate-shaped body, and
wherein an upper surface of the plate-shaped body has first recesses that form steam ducts and a lower surface of the plate-shaped body has second recesses that form predetermined breaking points.

23. A module for a heat pump, comprising:
a housing;
an adsorption/desorption region, wherein in the adsorption/desorption region, a bundle of tubes through which fluid can flow is arranged; and
a supporting structure that forms a mechanical support for a wall of the housing against an action of an external pressure,
wherein the housing encloses the bundle of tubes and a movable working medium in a sealing manner, and
wherein the supporting structure is arranged parallel to a longitudinal extent of the bundle of tubes

the module further comprising an adsorber structure comprising:
an adsorbent, wherein the working medium can be adsorbed and desorbed on the adsorbent, and the adsorbent is thermally connected to at least one tube of the bundle of tubes in the adsorption/desorption region,
