How do I choose a heat exchanger?
Main Criteria for Heat Exchanger Sizing and Selection For a gasketed plate heat exchanger, the gaskets must be compatible with the fluids in the unit.
Thermal fluid characteristics and product mix.
If the heating or cooling fluid is susceptible to fouling, a corrosion resistant material may be needed.
What is the most efficient heat 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. With high viscosities, a special tubular may be required.
What are the different types of heat exchangers?
Types of Heat ExchangersShell and tube heat exchangers.Double pipe heat exchangers.Plate heat exchangers.Condensers, evaporators, and boilers.
How many types of exchangers are there?
The two main types are finned and unfinned tubular. With a finned tubular heat exchanger, both fluids are unmixed, the one between the fins is guided in a direction transverse to the tube flow direction. In the unfinned exchanger heat can be exchanged in all directions, and the fluid can mix.
What is exchanger and types?
Types. Double pipe heat exchangers are the simplest exchangers used in industries. … Double-pipe heat exchanger (a) When the other fluid flows into the annular gap between two tubes, one fluid flows through the smaller pipe. The flow may be a current flow or parallel flow in a double pipe heat exchanger.
What is a 1/2 Heat Exchanger?
Shell and tube heat exchanger design. … Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fluid in the tubes passes through the fluid in the shell. In a single pass heat exchanger, the fluid goes in one end of each tube and out the other.
