AI Technical Summary
Technical Problem
Existing heat exchangers face challenges in achieving optimal surface finish and wall thickness control, leading to inefficiencies in heat transfer, turbulence, and increased weight due to rough surfaces and thicker walls.
Method used
A method of electroforming heat exchangers involves polishing a conductive mandrel surface to a smooth finish (rms < 32 microinches) and electroforming a heat exchanger with thin walls (3-4 mils) to integrate tubes and manifolds as a monolithic unit, reducing porosity and turbulence.
Benefits of technology
The method results in improved heat transfer, reduced weight, and lower manufacturing costs by achieving smoother surfaces and thinner walls, enhancing thermal conductivity and structural integrity.

Abstract
To provide an additive heat exchanger and a method of forming.SOLUTION: A method of electroforming can be used to prepare a heat exchanger by electroforming the heat exchanger on a mandrel having a smooth and conductive surface. The mandrel is in the shape of at least part of the heat exchanger, and is removed from the electroformed heat exchanger.SELECTED DRAWING: Figure 2
