What type of heat exchanger consists primarily of a bundle of tubes encased in a shell?

Explanation:
The main idea is recognizing the construction that defines the exchanger. A shell-and-tube heat exchanger is identified by a bundle of tubes enclosed inside a larger shell. One fluid runs through the tubes, while the other flows around the tubes inside the shell, allowing heat transfer between the two. This design yields a large surface area and is well-suited for high pressures and temperatures, with the ability to clean or inspect the tube side. Plate-type exchangers, by contrast, use flat plates forming narrow channels between them, not a tube bundle in a shell. The other named variants don’t describe the tube-bundle-in-shell arrangement, so the correct type is the shell-and-tube design.
