## Abstract

A heat exchanger has a turbulating insert arranged between a pair of plates. The turbulating insert is permeable to fluid flow in both a high-pressure-drop direction and a low-pressure drop direction. One portion of the turbulating insert has the high-pressure-drop direction oriented at a non-zero angle to the high-pressure-drop direction of another portion. A method of making the heat exchanger includes forming a turbulating insert, removing a portion of the turbulating insert to create a cavity within the turbulating insert, placing the remaining turbulating insert into a stamped first plate, and placing the removed portion of the turbulating insert into the cavity at a non-zero angle of rotation relative to the remaining turbulating insert.

## Claims

### Claim 1

A method of making a heat exchanger, comprising:
forming a turbulating insert;
removing a portion of the turbulating insert to create an aperture within the remaining turbulating insert;
placing the remaining turbulating insert into a stamped first plate;
placing the removed portion of the turbulating insert into the aperture of the remaining turbulating insert; and
joining a stamped second plate to the stamped first plate to enclose the turbulating insert within a fluid volume created between the stamped first plate and the stamped second plate.

### Claim 2 (depends on 1)

The method of claim 1, wherein the removed portion of the turbulating insert is placed into the aperture at a non-zero angle of rotation relative to the remaining turbulating insert.

### Claim 3 (depends on 2)

The method of claim 2, wherein the non-zero angle is ninety degrees.

### Claim 4 (depends on 1)

The method of claim 1, wherein the removed portion of the turbulating insert exhibits rotational symmetry.

### Claim 5 (depends on 4)

The method of claim 4, wherein the removed portion of the turbulating insert has a square shape.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
forming a locating hole into the removed portion of the turbulating insert; and
using the locating hole to orient the removed portion of the turbulating insert within the aperture at a non-zero angle of rotation relative to the remaining turbulating insert.

### Claim 7 (depends on 6)

The method of claim 6, wherein using the locating hole to orient the removed portion of the turbulating insert within the aperture includes receiving a projection formed into the stamped first plate into the locating hole.

### Claim 8 (depends on 1)

The method of claim 1, wherein joining a stamped second plate to the stamped first plate includes either overlapping an outer perimeter of the first plate with an outer perimeter of the second plate or nesting the outer perimeter of the second plate within the outer perimeter of the first plate.

### Claim 9 (depends on 1)

The method of claim 1, wherein forming the turbulating insert includes lancing and offsetting a metal sheet at regular intervals and rolling the metal sheet to create corrugations.
