Designing the Most Effective Heat Exchanger
The 3D-printing method is ideal for high-temperature, high-pressure heat exchangers because the exchanger itself is composed of a single block—there are no welded or brazed joints that can fail, Narayanan said. In addition to maintaining strength, a 3D-printed exchanger must resist gas corrosion, meaning material choice is important.
