What are concentric tube heat exchangers used for?
Concentric Tube (or Pipe) Heat Exchangers are used in a variety of industries for purposes such as material processing, food preparation, and air-conditioning.
What is a multiple pipe heat exchanger?
Double Pipe Heat Exchanger is a hairpin heat exchanger may have only one inside pipe, it may have multiple inside tubes, but it will always have the doubling back feature shown. The pipes are usually doubled back multiple times as shown in the diagram at the left, in order to make the overall more compact.
What are the two 2 possible arrangements for a concentric tube heat exchanger?
The two possible arrangements would be parallel flow and counterflow.
What are concentric pipes?
A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn’t need to remain level.
What is the most effective heat exchanger?
Plate exchanger
Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important. However, a plate heat exchanger regenerator is restricted to low viscosities.
What is a pipe heat exchanger?
The double pipe heat exchanger is, in its simplest form, one pipe held concentrically inside of a larger pipe (thus the name “double pipe”). The inner pipe acts as the conductive barrier, where one fluid flows through this inner pipe and another flows around it through the outer pipe, forming an annulus shape.
What is the difference between double pipe and shell-and-tube heat exchanger?
Double pipe heat exchanger consists of two concentric pipes of different diameters. One pipe is for hot fluid and another is for cold fluid. Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present. One fluid hot or cold flow in shell and other hot or cold flow in the tubes.
What are the types of heat exchanger?

What are the four types of heat transfer?
Various heat transfer mechanisms exist, including convection, conduction, thermal radiation, and evaporative cooling.
