heat exchanger

A heat exchanger is a device that transfers heat between two fluids—liquids or gases—without mixing them. It’s commonly used in systems like air conditioners, car radiators, and industrial processes. The fluids flow through separate channels or pipes, with heat passing through a barrier, allowing one fluid to cool down while the other heats up. This efficient transfer of heat helps regulate temperature, save energy, and improve performance in various applications. Essentially, a heat exchanger acts as a bridge that moves thermal energy efficiently from one place to another.
