A Heat Exchanger is a device designed to transfer heat between two or more fluids without mixing them. It is widely used in industries, HVAC systems, power plants, and chemical processes to efficiently heat or cool fluids. Heat exchangers come in various types, including shell-and-tube, plate, air-cooled, and double-pipe, depending on the application and process requirements. https://www.heatexchanger.co.in/Heat-Exchanger-Blog-Details/role-of-heat-exchangers-in-industries/
