Today we’re going to explain how exchangers...exchange heat. We’ll look at concentric tubes, finned tubes, plate heat exchangers, and shell-and-tube heat exchangers. And we’ll look at some equations to help us sort through heat transfer and decide what heat exchangers are best suited for our designs.
