A heat exchanger is a device that transfers heat between two fluids without mixing them, ensuring efficient energy utilization. It is widely used in industries such as power generation, HVAC, oil refining, and chemical processing. By recovering waste heat and optimizing temperature control, it enhances system performance, reduces energy consumption, and supports sustainable operations. https://www.heatexchanger.co.in/Heat-Exchanger-Blog-Details/role-of-heat-exchangers-in-industries/
