A hairpin heat exchanger is an advanced and compact thermal system designed to facilitate efficient heat transfer between two fluids. The exchanger consists of U-shaped tubes that allow hot and cold fluids to flow in opposite directions (countercurrent flow), maximizing heat transfer efficiency. Its key advantages include compact design, high heat transfer efficiency, durability, and ... https://www.finfancooler.com/Heat-Exchanger/Hairpin-Type-Heat-Exchanger/
