Heat Exchanger Design

A heat exchanger is a device that transfers heat between two or more fluids without them mixing. It’s commonly used in heating, cooling, and energy recovery applications. In design, engineers consider factors like flow arrangement (counterflow, parallel flow), surface area, material, and thermal properties to maximize efficiency. The goal is to effectively transfer heat while minimizing energy loss and ensuring safety. Common examples include radiators in cars and HVAC systems in buildings, where they help maintain comfortable temperatures by efficiently managing heat transfer.
