A hairpin heat exchanger is a type of tubular heat exchanger designed with two or more tubes bent into a U-shape, resembling a hairpin. This configuration allows efficient heat transfer between two fluids—one flowing through the inner tubes and the other through the shell side. The design supports counterflow or parallel flow, ensuring excellent thermal performance even under high-pre... https://www.unitedheatexchangers.com/blog/what-is-a-hairpin-heat-exchanger/
