Heat Exchanger
A Heat Exchanger is a device that transfers heat between two fluids without mixing them, like a car radiator cooling engine fluid with outside air. In buildings and industrial settings, these devices are crucial for heating, cooling, and temperature control. They're found everywhere from home furnaces to large industrial plants. Think of it like a special radiator that can either warm things up or cool them down, depending on what's needed. Companies often look for people who can design, install, maintain, or repair these systems.
