Abstract

A method of forming a component for a heat exchanger is disclosed. The method comprises machining a portion of a metal sheet to form a plurality of protrusions, and forming apertures in the portion of the metal sheet so as to form a plurality of ribs defined by adjacent ones of the apertures, wherein at least one protrusion is located on each of said ribs.

First claim

The invention claimed is:

1. A method of forming a component for a heat exchanger, the method comprising
grinding a portion of a metal sheet to form a plurality of protrusions; and then
forming elongate apertures in the portion of the metal sheet so as to form a plurality of elongate ribs defined between adjacent ones of the apertures;
wherein at least one protrusion is located on each of said elongate ribs;
wherein the plurality of protrusions include a plurality of pins.

2. The method of claim 1 , wherein the plurality of protrusions include protrusions having at least one of: chevron, teardrop, linear, diamond, oval, circular or airfoil cross sections.

3. The method of claim 1 , wherein the step of forming apertures comprises cutting the metal sheet at locations where protrusions are not present.

4. The method of claim 1 , wherein the plurality of ribs comprises at least 10 ribs.

5. The method of claim 1 , wherein the ribs defined by the apertures formed in the metal sheet have a regular geometric pattern.

6. The method of claim 1 , wherein the plurality of protrusions are formed in a regular geometric pattern.

7. The method of claim 1 , wherein the component is a heat exchanger plate for a laminate heat exchanger.

8. The method of claim 1 , comprising cutting the metal sheet to have an outer profile and an inner profile suitable for use in a heat exchanger and prior to said step of grinding the portion of the metal sheet.

9. The method of claim 1 , wherein said grinding a portion of a metal sheet to form a plurality of protrusions comprises removing material from a surface of the portion to leave the plurality of protrusions upstanding.

10. The method of claim 1 , wherein the plurality of ribs comprises at least 20 ribs.

11. The method of claim 1 , wherein each elongate rib is defined between two adjacent elongate apertures so that the rib has elongate side edges defined by the adjacent apertures.

12. The method of claim 1 , wherein a plurality of the protrusions are located along opposing elongated sides of each elongate aperture.

13. A method of forming a component for a heat exchanger, the method comprising
grinding a portion of a metal sheet to form a plurality of protrusions; and then
forming elongate apertures in the portion of the metal sheet so as to form a plurality of elongate ribs defined by adjacent ones of the elongate apertures;
wherein at least one protrusion is located on each of said elongate ribs.
