WebAs its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. Web2.7 HEAT TRANSFER ENHANCEMENT USING FINS We use a fin on a solid object to increase convective heat transfer by increasing surface area. The fin must be made of a good thermal conductor. Examples of this type of heat transfer enhancement include: Heat sinks on electrical equipment
