Abstract

A heat exchanger plate having a planar plate having an inlet and outlet proximate to a first edge of the heat exchanger plate. The planar plate having a plurality of ribs and a plurality of channels, with the plurality of channels being in a plane different from the planar plate. The plurality of channels being in fluid communication from the inlet to the outlet permitting fluid flow from the inlet to the outlet. A protrusion coupled to the planar plate proximate to the first edge of the heat exchanger plate and laterally extending from an axis, with the heat exchanger plate being susceptible to bending about the axis.

First claim

What is claimed is:

1. A heat exchanger plat; comprising:
a planar plate having an inlet and outlet proximate to a first edge of the heat exchanger plate and having a central rib extending along the length of the heat exchanger plate and separating the planar plate into an inlet side and an outlet side;
the heat exchanger plate having a plurality of ribs and a plurality of channels, with a base of the plurality of channels being in a plane different from the planar plate, the plurality of channels being in fluid communication from the inlet to the outlet permitting fluid flow from the inlet to the outlet; and
a protrusion coupled to the planar plate proximate to the first edge of the heat exchanger plate and extending away from an axis, with the heat exchanger plate being susceptible to bending about the axis and the axis extends in line with the central rib.

2. The heat exchanger plate according to claim 1 , wherein the planar plate provides a U-shaped fluid flow path from the inlet to the outlet.

3. The heat exchanger plate according to claim 1 , wherein the protrusion laterally extends away from the axis and intersects the axis, the protrusion being bar shaped with a centrally positioned pimple-shaped projection that projects from the protrusion along the central rib towards an edge of the heat exchanger plate that is opposed to the first edge.

4. The heat exchanger plate according to claim 1 , wherein the protrusion is a longitudinal shaped dimple positioned adjacent to the first edge of the heat exchanger plate and laterally extending away from the axis, the longitudinal shaped dimple intersecting the axis along which the heat exchanger plate is susceptible to bending.

5. The heat exchanger plate according to claim 1 , wherein the protrusion has a triangular shape and extends from the first edge of the heat exchanger plate, the apex of the triangular shaped protrusion being proximate to and in line with the central rib.

6. The heat exchanger plate according to claim 1 , wherein the protrusion laterally extends away from the axis and the protrusion is a flange extending from the first edge of the heat exchange plate.

7. The heat exchanger plate according to claim 1 , wherein the protrusion has a triangular shape and is coupled adjacent to the first edge of the heat exchanger plate, the apex of the triangular shaped protrusion being proximate to and in line with the central rib.

8. The heat exchanger plate according to claim 1 , wherein the protrusion comprises a first protrusion and a second protrusion, the first protrusion being longitudinal in shape and coupled to the planar plate proximate to the first edge of the heat exchanger plate and laterally extending away from the axis, with the heat exchanger plate being susceptible to bending about the axis; and the second protrusion being V-shaped with the apex of the V-shaped protrusion being aligned with the central rib of the heat exchanger plate.

9. The heat exchanger plate according to claim 1 , further comprising a protuberance positioned in the channel proximate to an edge opposed to the first edge, the protuberance intersects the axis about which the heat exchanger plate is susceptible to bending and extends laterally away towards the longitudinal edges of the heat exchanger plate.

10. A heat exchanger plate, comprising:
a planar plate having an inlet and outlet proximate to a first edge of the heat exchanger plate;
the heat exchanger plate having a plurality of ribs and a plurality of channels, with a base of the plurality of channels being in a plane different from the planar plate,
the plurality of channels being in fluid communication from the inlet to the outlet permitting fluid flow from the inlet to the outlet;
a protrusion coupled to the planar plate proximate to the first edge of the heat exchanger plate and extending away from an axis, with the heat exchanger plate being susceptible to bending about the axis; and
a plurality of nipples formed in the channel and extending in the fluid passage.

11. The heat exchanger plate according to claim 10 , wherein the plurality of nipples are formed proximate to an edge opposed to the first edge.

12. The heat exchanger plate according to claim 10 , wherein the heat exchanger plate has a manifold portion and a heat exchanger portion, the heat exchanger plate provided with a plurality of protrusions between the manifold portion and the heat exchange portion; and
wherein the heat exchanger is susceptible to bending in between the manifold portion and the heat exchanger portion.

13. The heat exchanger plate according to claim 12 , wherein the axis about which the heat exchanger plate is susceptible to bending is perpendicular to the length of the heat exchanger plate.

14. The heat exchanger plate according to claim 12 , wherein the plurality of protrusions are at an angle from the length of the heat exchanger plate.

15. A heat exchanger plate, comprising:
a planar plate;
a plurality of ribs and a plurality of channels formed into the planar plate such that a base of the plurality of channels is in a plane different from the planar plate;
an inlet and an outlet connected to the plurality of channels; and
a protrusion formed on the planar plate and separate from the plurality of channels, and the protrusion extending perpendicularly to and away from a central rib of the plurality of ribs.

16. The heat exchanger plate of claim 15 , wherein the protrusion is formed as a dimple in the planar plate separate from the plurality of channels.

17. The heat exchanger plate of claim 15 , wherein the protrusion further extends in the direction of the central rib.

18. The heat exchanger plate of claim 15 , wherein the protrusion is formed as a bent edge of the planar plate.

19. The heat exchanger plate of claim 15 , further comprising a protuberance positioned in one or more of the plurality of channels on an end of the heat exchanger plate opposite the protrusion and the protuberance extending perpendicularly to the central rib.
