Heat exchangers are vital devices used to transfer heat between two or more fluids without mixing them. Common types include shell-and-tube, plate, air-cooled, double-pipe, spiral, and finned-tube exchangers. Each type serves specific applications based on temperature, pressure, and fluid properties. Flow configurations like counterflow, parallel flow, and crossflow impact efficiency.... https://alaquainc.com/heat-exchanger-types-benefits-and-applications-explained/
