A heat exchanger is a device that transfers heat between two fluids without mixing them, ensuring efficient energy use. It is widely used in industries such as power generation, HVAC, chemical processing, and oil refining. By recovering and reusing heat, it helps improve system efficiency, reduce energy costs, and support sustainable operations. https://www.heatexchanger.co.in/Heat-Exchanger-Blog-Details/role-of-heat-exchangers-in-industries/
