Heat exchanger types

Do you know the different types of heat exchangers? What are the types of heat exchange? What type of heat exchanger is more efficient? Do heat exchangers really save energy? There are three primary classifications of heat exchangers according.

Heat exchanger Flow arrangement.

Double pipe heat exchangers are the simplest exchangers used in industries. One of the widest uses of heat exchangers is for air conditioning. Other design characteristics available for this type of heat exchanger include finned tubes , single- or two-phase heat transfer , countercurrent flow , cocurrent flow , or crossflow arrangements , and single , two , or multiple pass configurations.

There are four main types of tube layout , which are, triangular (30), rotated triangular (60), square (90) and rotated square (45). The triangular patterns are employed to give greater heat transfer as they force the fluid to flow in a more turbulent fashion around the tubing. Plate and shell heat exchanger. A third type of heat exchanger is a plate and shell heat exchanger , which combines plate heat exchanger with shell and tube heat exchanger technologies.

The heart of the heat exchanger contains a fully welded circular plate pack made by pressing and cutting round plates and welding them together.

In the parallel-flow arrangement, the hot and cold fluids enter at the same en flow in the same direction, and leave at the same end. In the counter-flow arrangement, the fluids enter. DIRECT CONTACT TYPE HEAT EXCHNAGER : In direct contact type heat exchanger both hot fluid. REGENERATIVE OR STORAGE TYPE HEAT EXCHANGER : When flow of fluid is. But of the three, the counter flow heat exchanger design is the most efficient when comparing heat transfer rate per unit surface area.

All heat exchangers are used to transfer heat from one fluid to another. Many different exchanger configurations can be easily created by different combinations of front en shell and rear end.

Shell and Tube Exchangers – are the most widely used exchangers in a variety of industries.

This has given rise to certain standards for the design of heat shell and tube exchangers. TEMA (Tubular Exchangers Manufacturers Association) standards are most widely recognized heat exchangers design standards. In the simplest heat exchanger ,. Parallel-flow and counterflow.

The fluids can also flow in perpendicular directions which is known as cross flow. The shell-and-tube heat exchanger is composed of a shell containing. It is widely used in the process industries as well as in many types of HVAC equipment.

Uses for these workhorses of heat transfer include heat removal in chillers, condensers, and reboilers, process stream cooling, and as critical parts of evaporative cooling and refrigeration systems. TEMA B and TEMA R are similar in requirements and typically require features like, confined gaskets joints,. Fixed tubesheet heat exchanger. This is a very popular version as the heads can be removed to clean the inside of the tubes.

The front head piping must be unbolted to allow the removal of the front hea if this is undesired this can be avoided by applying a type A front head.
