Which heat exchanger type consists of tubes containing one fluid and a shell containing another fluid, with the shell forming the outer surface?

Which heat exchanger type consists of tubes containing one fluid and a shell containing another fluid, with the shell forming the outer surface?

• A. Shell and Tube Type Heat Exchangers
• B. Straight Tube
• C. U-Tube
• D. Multi-Pass HXR

Answer: (A)

Heat exchangers transfer heat between two fluids without mixing them, and the shell-and-tube type is defined by a large shell that surrounds a bundle of tubes. One fluid flows through the tubes while the other flows on the shell side around those tubes, with the shell forming the outer boundary of the unit. This arrangement precisely matches the description: a fluid inside tubes and the other fluid contained by the outer shell. It’s a robust, widely used design for handling high pressures and temperatures, and it can be arranged in various ways (multi-pass, different tube layouts) to optimize heat transfer. The other options describe different tube configurations or flow arrangements, but they don’t define the overall shell-surrounded-tubes geometry as clearly as the shell-and-tube type.
