Abstract
A method for forming a heat exchanger plate includes providing a precursor having a body with a first face and a second face opposite the first face and at least one internal passageway; and pluralities of first and second fin precursors respectively protruding from the first and second faces. First and second fin height profiles are formed by removing material from the respective fin precursors via wire electro-discharge machining.

A method for forming a heat exchanger plate, the method comprising:
- providing a precursor having:
- a body with a first face and a second face opposite the first face and at least one internal passageway;
- a plurality of first fin precursors protruding from the first face;
- and
- a plurality of second fin precursors protruding from the second face;
- and
- forming a first fin height profile of a first plurality of fins by removing material from the first fin precursors via wire electro-discharge machining;
- and
- forming a second fin height profile of a second plurality of fins by removing material from the second fin precursors via wire electro-discharge machining.
