Abstract

A heat exchanger plate, where the plate is provided with a heat transfer surface having a corrugated pattern with a plurality of ridges and valleys, and where the heat exchanger plate is provided with a plurality of guiding sections, and where each guiding section has a first guiding surface and a second guiding surface, where the first and second guiding surfaces are perpendicular to each other. A heat exchanger having a plurality of heat exchanger plates is also disclosed. The advantage of this heat exchanger plate is that it allows for an improved alignment of the heat exchanger plates.

First claim

The invention claimed is:

1. A heat exchanger plate configured to be used together with other heat exchanger plates in a heat exchanger, the heat exchanger plate possessing a perimeter edge and comprising a heat transfer surface having a corrugated pattern with a plurality of ridges and valleys, the heat exchanger plate and said other heat exchanger plates each comprising at least two separated guiding sections, the two separated guiding sections of the heat exchanger plate being of a same configuration as the two separated guiding sections of said other heat exchanger plates, wherein each guiding section comprises a first guiding surface and a second guiding surface, wherein the first and second guiding surfaces are perpendicular to each other, one of the two guiding sections being configured to define a first structure and the other of the two guiding sections being configured to define a second structure, the first and second structures possessing respective configurations different from one another, and the first structure of the heat exchanger plate being configured to be fitted into the second structure of an adjacent heat exchanger plate, where the first guiding structure and the second guiding structure are spaced from the perimeter edge of the heat exchanger plate.

2. The heat exchanger plate according to claim 1 , wherein the first guiding surface and the second guiding surface are straight guiding surfaces.

3. The heat exchanger plate according to claim 1 or claim 2 , wherein each of the guiding sections is provided at a respective corner of the heat exchanger plate.

4. The heat exchanger plate according to claim 1 or claim 2 , wherein the guiding sections further comprise a third guiding surface and a fourth guiding surface, wherein the third and fourth guiding surfaces are also perpendicular to each other.

5. The heat exchanger plate according to claim 4 , wherein the third guiding surface and the fourth guiding surface are straight guiding surfaces.

6. The heat exchanger plate according to claim 4 , wherein the first and the third guiding surfaces are parallel to each other, and the second and the fourth guiding surfaces are parallel to each other.

7. The heat exchanger plate according to claim 4 , wherein the third and fourth guiding surfaces are positioned between a basis surface level and a recessed corner surface.

8. The heat exchanger plate according to claim 1 or claim 2 , wherein the guiding sections further comprise a recessed surface being parallel to a basis surface level of the heat exchanger plate, the recessed surface having a pressing depth that is greater than the corrugated pattern of the heat transfer surface of the heat exchanger plate.

9. The heat exchanger plate according to claim 1 or claim 2 , wherein the first and second guiding surfaces are comprised on a support knob.

10. The heat exchanger plate according to claim 1 or claim 2 , wherein the first and second guiding surfaces are comprised on two different support knobs.

11. A heat exchanger comprising a plurality of heat exchanger plates according to claim 1 or claim 2 .

12. The heat exchanger plate according to claim 1 , wherein one of the guiding sections includes an upstanding support knob, and including a first surface positioned immediately adjacent one side of the upstanding support knob and recessed relative to the upstanding support knob, and a second surface positioned immediately adjacent an opposite side of the upstanding support knob and recessed relative to the upstanding support knob, the first guiding surface being provided on one side of the upstanding support knob and the second guiding surface being provided on another side of the upstanding support knob.

13. The heat exchanger plate according to claim 1 , wherein one of the guiding sections includes first and second spaced apart upstanding support knobs, and including a surface positioned between the first and second spaced apart upstanding support knobs and recessed relative to the first and second spaced apart upstanding support knobs, the first guiding surface being provided on one side of the first upstanding support knob and the second guiding surface being provided on one side of the second upstanding support knob.

14. A heat exchanger comprising a plurality of heat exchanger plates each possessing a perimeter edge, the plurality of heat exchanger plates including a first heat exchanger plate and a second heat exchanger plate that are adjacent to each other, each heat exchanger plate possessing:
a heat transfer surface having a corrugated pattern with a plurality of ridges and valleys, and
first and second guiding sections, the first and second guiding sections each having a first guiding surface and a second guiding surface that are perpendicular to each other,
the first and second guiding sections defining respective structures, the structure defined by the first guiding section of the first heat exchanger plate being fitted into the structure defined by the second guiding section of the second heat exchanger plate so that the first guiding surface of the first guiding section of the first heat exchanger plate contacts a surface of the second guiding section of the adjacent second heat exchanger plate that is opposite the first guiding surface of the second guiding section of the second heat exchanger plate, and the second guiding surface of the first guiding section of the first heat exchanger plate contacts a surface of the second guiding section of the adjacent second heat exchanger plate that is opposite the second guiding surface of the second guiding section of the second heat exchanger plate to align the first and second heat exchanger plates, where the first guiding structure and the second guiding structure are spaced from the perimeter edge of the respective heat exchanger plate.

15. The heat exchanger according to claim 14 , wherein the first guiding surface of the second guiding section of the first heat exchanger plate contacts a surface of the first guiding section of the adjacent second heat exchanger plate that is opposite the first guiding surface of the first guiding section of the second heat exchanger plate, and the second guiding surface of the second guiding section of the first heat exchanger plate contacts a surface of the first guiding section of the adjacent second heat exchanger plate that is opposite the second guiding surface of the first guiding section of the second heat exchanger plate to align the first and second heat exchanger plates in only one direction.

16. The heat exchanger according to claim 14 , wherein the first guiding surface and the second guiding surface of each guiding section are straight guiding surfaces.
